Dean’s MessageI am very pleased to communicate withyou again in this second issue of CUAEngineer. After launching the inauguralissue of the CUA Engineer last year, ourschool has received many complimentsfrom its readers including our faculty, staff,students and alumni and also from administratorsof engineering schools around thecountry. We would like to thank you foryour support and hope to continue toenhance both the size and the quality ofthis publication to meet your expectation.Like the previous year, 2006–2007 has been an exciting one filled withactivities. We continued to expand our academic programs and researchcollaboration with universities in Asia. Highlights of the academic year2006–2007 are presented as follows.■ In the fall semester of 2006, the school welcomed 86 new undergraduatestudents including nine transfer students, representing an 83 percentincrease in new undergraduate students as compared to last year. Thegraduate enrollment has been steady in the last three years. At the schooldiploma distribution ceremony in May 2007, the school granted 40 bachelor’sdegrees, 79 master’s degrees and three doctoral degrees to the graduates.The names of the graduates are listed on the back page of this issue.■ Our faculty continued to be very active in research in terms of researchproposal submission, journal publication and conference participation.The number of published papers and submitted proposals increased substantiallyfrom last year, as reported in the faculty section of this issue.Two members of our faculty received the prestigious National ScienceFoundation CAREER awards for their research. In addition, two engineeringfaculty members received the 2007 CUA provost’s awards for excellencein teaching and research, respectively. See the articles in this issue formore information about the above award recipients.■ At the 2006 annual homecoming luncheon in October 2006, DavidDidion, B.M.E. 1963, M.M.E. 1963, D.Engr. 1972, received the 2006Engineering Distinguished Alumni Achievement Award. About 80 peopleattended the luncheon. For full story please turn to page 7.■ The school continued to carry out activities for the maintenance of the ABETaccreditation and has actively prepared for the upcoming re-accreditationvisit in October 2007. The engineering chairs will submit their self-studyreports to ABET by July 1, 2007, and will start finalizing the details for thevisit. After registering for the Fundamental Examination (FE) in June 2006,the engineering juniors took the exam in October 2006. The exam resultsthat I received from NCEES in April 2007 showed some score improvementas compared to last year. The FE results have been incorporated into theoutcome assessment of our engineering programs.■ Three new faculty members—an assistant professor of electrical engineeringand computer science, an assistant professor of civil engineering andan assistant professor of biomedical engineering—join our school inSeptember 2007. Two new staff members joined the school to fill thenewly created receptionist position and the vacant position of the assistantto the dean for project management. Please read the new faculty andstaff section for more details.■ I am happy to inform you that a new faculty fellowship program wasestablished thanks to a generous donation made by the Burns family,four of whose members graduated from our school. This fellowship,named the Burns Faculty Fellowship, will be awarded annually to juniorengineering faculty members to support their research activities. Pleaseread the related article in this issue to learn more about the Burns familyand this new fellowship program.■ For 11 days in October 2006, I visited five major cities of China and severalmajor Chinese universities including Tsinghua University, PekingUniversity, Southeast University, Yangzhou University, the Hong KongUniversity of Science and Technology and the Hong Kong PolytechnicUniversity (PolyU). During the trip, we signed memoranda of understandingwith the above universities for potential collaborative educationalprograms and faculty research collaboration. For more information aboutthe above trip and the established student exchange program, pleaseread the related stories in this issue.■ During a 10-day trip In March 2007, I traveled to Singapore andMalaysia to visit The National University of Singapore and the NanyangUniversity of Singapore and three campuses of the INTI College inMalaysia. See related stories for more details.■ In April 2007 the school signed a MOU with the International Universityof the Vietnam National University-Ho Chi Minh City in Ho Chi Minh City,Vietnam, for CUA and HCMIU to start exploring 2+2 and 4+1 degreeprograms. CUA requested and received approval from the CUA AcademicSenate Undergraduate Board to establish the 2+2 programs with theabove university partners. See related article for more details.■ The off-campus master’s degree programs, including the EngineeringManagement Program and the on-site programs at NIH and NSWC-Carderock, are going strong with good enrollment. Recently the schoolwon a proposal for an on-site graduate program at the Department ofthe Army-Fort Belvoir and will start offering courses there in the fallsemester of 2007.As presented above, the school has done very well in the academic year2006–2007 in all aspects including enrollment, research, fundraising andprogram development and we are very proud of its success. I am happy towitness the seeds we planted in the educational programs in Asia in thelast several years began to germinate into some concrete educational programsand international collaboration as the school moves into a new eraof engineering education aiming at producing global leaders. I hope you willenjoy reading this second issue of CUA Engineer and as always I look forwardto receiving your feedback.Charles Cuong NguyenDean, School of Engineeringnguyen@cua.edufall2007 | 1

cuaengineerFaculty ProfileLasering in on DifferencesGiven that Assistant Professor of Mechanical Engineering John Judge hasthree children under the age of five, it’s fitting that when describing hisresearch, he channels Sesame Street and its classic line: “One of thesethings is not like the others.”In fact, Judge has spent his research career looking for things that arenot as they appear — specifically for that one thing that is not like theothers, even if the differences are hidden to the naked eye. Judge findsthose subtle differences — often in micromechanical systems that couldfit on the head of a pin — by looking at vibration.Judge, who received both the 2007 provost’s teaching award and theBurns Faculty Fellowship, says his research focuses on how small differencesin the shape or size of one part of a micromechanical system, whenall parts are ostensibly identical, can translate into huge differences in thesystems’ vibration behavior. Understanding these effects is crucial fordeveloping new uses for micro- and nanotechnology, such as tiny, ultrafastmechanical resonators for filtering and processing electrical signals, orultra-sensitive arrays of sensors for chemical and biological agents.These days, Judge is using vibration to spot pieces of earth that are notlike the others — plots that may be hiding land mines or improvised explosivedevices, roadside bombs that have been a major weapon of insurgents inIraq. He and a colleague, Assistant Professor of Mechanical Engineering JoeVignola, have created a five-axis laser that detects subtle changes in vibration.Its beam projects down onto a section of ground, and sends a reading to acomputer indicating any abnormal vibration.“You look at the ground and it all looks identical to the naked eye,” Judgesays. “But if you measure how the ground vibrates, the land right above alandmine vibrates differently from undisturbed ground.” In addition to militaryapplications, the technology could aid humanitarian efforts as a land minedetector in places like Vietnam, where villagers and children are still beingkilled or maimed by long-forgotten land mines.Other laser systems currently in development require up to three lasersto gain an accurate reading of a target. Judge’s laser boasts both accuracyand versatility — operating on three moving axes so that one laser canassess an area, moving up and down, front to back, and left to right. Tworotational axes allow a mirror to further direct the laser’s beam, so measurementscan be made from any angle. It’s like having three lasers for theprice of one. Given that vibration-detection lasers can run $200,000 permachine, that’s a serious cost benefit.Judge and Vignola are also working on adding a telescope lens to alaser, to allow it to measure vibration from up to 100 meters away. It couldprovide lifesaving technology for armed forces in Iraq and Afghanistan,where a significant number of fatalities are the result of hidden roadsidebombs. “There’s a rock by the side of the road, but is it really a rock or is itan IED disguised as a rock?” Judge asks. In Judge’s vision, a soldier couldpoint the laser at the object from a safe distance and find the answer —before his convoy is on top of it.Sometimes, being “not like the others” has its benefits. Luckily, Judgeknows when to be different.Assistant Professor John Judge2 | cuaengineer

cuaengineerFaculty ProfileTeaching Signals to ShareWhen most people pick up a cell phone, they’re not thinking about the other160 million users in the United States sharing the air space. They’re justtrying to make a call.Lucky for them, CUA electrical engineering professor Phil Regalia is notmost people.“Everyone has to learn to peaceably coexist in the same radio spectrum,”Regalia says of the ever-expanding, wireless-phone market. And it’s anedict easier said than done.For an increasingly contentious band of rival networks, getting their pieceof the airwave pie has become a game of “who can shout the loudest.”“It’s sort of like being in a crowded room of reporters, where you’re tryingto ask questions at the microphone,” Regalia explains. “There is all thiscommotion — everyone’s talking at once — and then one person gets tospeak again and everyone else eventually quiets down.”For years, cell phone providers have all broadcast simultaneously, sharingthe same radio frequency, through a technique called “code division multipleaccess,” based on assigning separate signature codes to each user, until amaximum number of distinguishable codes are allotted.But the United States and nations across the world are rapidly reaching apoint of frequency saturation, as the number of these wireless deviceskeeps expanding.“Pretty soon, everything will be wireless so the issue of getting that manywireless transmitters to function simultaneously is a big, open problem,”Regalia says. “There’s not going to be enough periods of silence left.”In other words, the shouting match has left everyone short of breath. Thatmeans it won’t be enough for networks to simply cooperate “peaceably,”they’re going to have be smarter about the ways they share their resources.The National Science Foundation seems to agree: It recently providedRegalia with a three-year, $120,000 grant to study more intelligent ways toshare the radio resource spectrum of these high-occupancy channels.Currently, each network user is “taught” to send its signals in between oraround other users’ signals, so they can transmit simultaneously. But thesesimultaneous signals are treated as interference, and this lowers the usabledata rate, or how much information can be sent.The professor likens this to a “wifi” hotspot, like the local Starbucks,where too many customers are trying to use the Internet on their laptops atonce, slowing down the whole system.Regalia’s research focuses instead on how the wave forms are behaving,so that networks can understand the behavior and make more intelligentchoices such that a message passes through as though there were nointerference. The basic technique was first discovered in the 1980s anddubbed “dirty paper coding,” based on the analogy of finding the remainingwhite space on paper that already has writing, or is “dirty.” In this way,existing messages on the paper need not impede the paper from carryingadditional messages. The method lay dormant for many years since its successfulapplication is dependent on resolving many technical problems incoding and radio modulation, whose solutions are the goal of ProfessorRegalia’s research.While he acknowledges the problem of shrinking capacity, Regalia takescomfort in the notion that necessity is the mother of invention. And he’shard at work to ensure she provides some offspring.fall2007 | 3

cuaengineerStudy Abroad Program Established with Hong Kong Polytechnic UniversityBeginning January 2008, CUA engineering studentswith an interest in the global classroom will get achance to pack their bags—and their T-squares—to participate in a rite of passage so often elusive toundergraduate engineers: a semester abroad.Historically, juniors in the CUA School ofEngineering resigned themselves to trading in astudy abroad program for a semester in PangbornHall in an engineering classroom. Like nursingprograms and other academic pursuits thatrequire specific, intensive science and mathcourses, engineering requirements made it difficult,if not impossible, for CUA engineering students toexperience life, culture and academics in anothercountry. However thanks to a memorandum ofunderstanding that the school signed with theHong Kong Polytechnic University in 2006, onJan. 16, 2007 Dean Nguyen and CUA ProvostJohn Convey and Alex Wai, Ph.D., dean of theFaculty of Engineering of PolyU signed an agreementto establish a student exchange programbetween the two institutions.Under this program, qualified engineeringstudents at CUA may study abroad at PolyU duringthe second semester of their junior year. The CUAengineering programs—biomedical, civil, electricaland mechanical engineering and computerscience—have developed modified curricula fortheir study abroad students to ensure that theycan graduate on time. In particular, coursesapproved against the modified curricula andtaken by the study abroad students can betransferred to the CUA degree programs. Sinceparticipating students will pay full-time tuition atThe MOU signing ceremony at the Hong Kong Polytechnic UniversityCUA for the study abroad and will not pay tuitionat PolyU, there will be no change in their existingfinancial aid arrangement in terms of their federaland CUA grants and scholarships. The studyabroad program is also financially attractivebecause the monthly expense including roomand board at PolyU is about $660 as comparedto that of $1,100 at CUA. Students from PolyUcan come to study at CUA under similar arrangementsto the CUA students. Language is not abarrier because all courses are in English atPolyU as Hong Kong was under the Englishinfluence for many years.PolyU is a public university with 12,000 studentsand excellent instructional and research facilities.Hong Kong, where PolyU is located, is a verydynamic and prosperous metropolitan citywith fabulous sightseeing attractions and internationalcuisine.“This study abroad program was established toeffectively deal with the impact of globalization onfuture engineering workforces. Students participatingin this program will gain global knowledge thatwill undoubtedly enhance their job market valuewhen they graduate. The combination of a solidengineering education at CUA and a semesterabroad at an application-oriented institution likePolyU with excellent laboratory facilities willprovide the participating students with a uniqueengineering education,” says Dean Nguyen.Dean Nguyen at his presentation to faculty and students at Southeast University inNanjing, ChinaDean Nguyen with faculty and students of Southeast University in Nanjing, China4 | cuaengineer

cuaengineerSchool of Engineering Explores Research and Educational Opportunities inChina, Singapore and MalaysiaDean Nguyen has traveled extensively throughout Asia over the last two yearsvisiting more than five Asian countries, forging relationships with universitypresidents and faculty and crafting memoranda of understanding (MOU) withmajor engineering institutions. The established relations would includesemester-abroad options and dual-attendance programs such as a 2+2bachelor program, with two years of study at CUA and two years at a partnerschool. As a result of last year’s trip to Asia, a proposal for the establishmentof 2+2 programs with two universities in Vietnam and Taiwan wasrecently approved by the Undergraduate Board of the CUA Academic Senate.Nguyen is also working to establish another option known as a 4+1 bachelor’s/master’sprogram, enabling a student to simultaneously receive a bachelor’sdegree at one university and a master’s degree at the partnering university.The partnership will also encourage faculty collaborations betweenschools, including sabbatical leaves and joint authorship of research papers.These partnerships will provide a mechanism, allowing for the best andbrightest Asian students to attend CUA for a semester in the semesterabroadoption or two years in the 2+2 programs—and hopefully entice themto return for graduate school. Drawing qualified graduate students fromother countries to pursue master’s and doctoral (Ph.D.) degrees at CUA is along-term objective of these programs, according to Dean Nguyen, who saysthere is a shortage of qualified graduate students to fill these degree programs.And given that approximately 70 percent of the faculty members atthese partner universities earned their advanced degrees at major U.S. universities,says Nguyen, it makes sense to advertise CUA as a top choice forforeign engineers looking to continue their education in the United States.Last fall, the dean’s city-hopping schedule packed six universities in fourcities into just 11 days. The trip began in Beijing at what Nguyen refers toas the “Harvard and MIT of China,” Tsinghua University and PekingUniversity, where the country’s prestigious engineering schools are located.Accompanied by Professor Frank Pao, the engineering school’s director ofdevelopment of international engineering programs, Nguyen then traveledfrom Beijing to Hong Kong, stopping along the way in Nanjing, Yangzhou andShanghai. During the fall semester of his trip, he visited SoutheastUniversity, Yangzhou University, the Hong Kong University of Science andTechnology and the Hong Kong Polytechnic University. At each institution,the dean met with university presidents, as well as deans and engineeringprofessors, offering presentations about CUA, its academic programs andpartnership opportunities to each school. At a result of this trip, the deansigned memoranda of understanding (MOU) with Southeast University andHong Kong Polytechnic University to explore educational and researchopportunities between the institutions.Continuing to expand the scope of the CUA international programs, thedean traveled to universities in Singapore and Malaysia during the springsemester. In Singapore, he visited the National University of Singapore andthe Nanyang University of Singapore, and in Malaysia, three campuses ofthe INTI College. As a result of this trip, the School of Engineering signeda MOU with the INTI College to explore the development of 2+2 and 4+1programs with this college. The dean is exploring a student exchangeprogram with Nanyang University of Singapore.Dean Nguyen says he plans to ease his globetrotting travels after avisit to schools in Bangalore, India, sometime in the next year. His choiceof partnering countries and universities is strategic and follows one hotlydebated business trend: outsourcing. Asian countries, along with India,have become the major recipient of a diffusion of engineering work asmore American companies shift production overseas.“We need to look to the future and prepare for that,” Nguyen says.“We’re going to train our students to not only become competent engineers,but also to have great potential to become managers and leaders in theengineering global market.” He is confident that a CUA student who boastsengineering-abroad studies in China, Vietnam or another foreign countrywill make them a more attractive candidate in the professional world.And one CUA engineering professor, in particular, may take some pride inthe dean’s most recent pick of partnering schools: Associate Professor ofCivil Engineering Lu Sun is a graduate of one of the engineering school’slatest partners, Southeast University in Nanjing, China.Dean Nguyen received an honorary professorship from President Lui of SoutheastUniversity in Nanjing, China.Signing ceremony of MOU between CUA and INTI College, Subang, Malaysiafall2007 | 5

cuaengineerCollaborative 2+2 Programs Approved for Taiwan and VietnamIn May 2007, the undergraduate board of the CUAAcademic Senate approved a proposal submittedby the School of Engineering, SOE, to establish2+2 programs with two universities in Asia: TheFu Jen Catholic University, FJCU, in Taiwan andthe International University of the VietnamNational University-Ho Chi Minh City, HCMIU, inVietnam. The approved 2+2 programs with thetwo Asian universities will enable the SOE toaccept Asian students who complete the firsttwo years at their home institutions and intendto complete the last two years at the SOE in adegree program.The establishment of the 2+2 programs isthe result of the following up of a memorandumof understanding, MOU, that the SOE signedwith the FJCU during Dean Nguyen’s trip toTaiwan last year and an MOU with the HCMIUin April 2007.Students from FJCU and HCMIU who wish tobe admitted to the 2+2 programs must successfullypass two evaluation stages, the first withthe CUA Office of Undergraduate Admissions(OUA) and the second with the SOE. They mustEngineering Faculty Earn Nearly $2 Million in GrantsThis past academic year, five members of the CUA engineering school wereawarded significant grants from the National Science Foundation and theU.S. Department of Veterans Affairs’ Rehabilitation Research and DevelopmentService totaling almost $2 million.The awards include two NSF Faculty Early Career Development, CAREER,Program awards and an Early Career Award from the Wallace H. CoulterFoundation. The NSF CAREER award seeks to honor young scientists whoseactivities best integrate the realms of research and education, building thebasis for long-term contributions to their fields. It is considered the foundation’smost prestigious award in early career development.“The School of Engineering is thrilled to have three members of ourfaculty distinguished for their work at such an early age in their careers,”said Dean Nguyen. “They have joined a team of cutting-edge scientists, asPeter Lum, Phillip Regalia, Otto Wilson and Lu Sun6 | cuaengineerapply to OUA as international transfer students.Their admissibility to CUA will be first evaluatedby the admission criteria set by OUA for transferand international students, which may includeGPA, equivalent SAT scores and English proficiency.After the students meet the standards ofthe OUA as general international transfer applicants,their credentials will be further evaluatedby the SOE. This second evaluation may considerletters of recommendation from former teachers,knowledge of relevant technical subjects andprospects for success at the School of Engineering.The students will not be officially admitted to theproposed 2+2 program until they are approved byboth OUA and the SOE.These 2+2 programs are the first-ever internationalprograms established at the SOE. DeanCharles Nguyen reacted enthusiastically to theUndergraduate Board’s approval of the 2+2 programs.“These programs will not only enhancethe diversity and internationality of our school,but also potentially help resolve the shortage ofqualified graduate students and research assistants.We hope to encourage the participatingstudents to continue their graduate studies withus after they finish.” The SOE expects to welcomethe first group of students from Vietnam inSeptember 2007.Dean Nguyen and the administrators of Saigon TechnologyUniversity in Ho Chi Minh City, Vietnamevidenced by other grants recently awarded to their colleagues.”Lu Sun, associate professor of civil engineering, has been awarded a fiveyear,$410,000 NSF CAREER award to study the effects of vehicle traffic onhighway design. Otto Wilson, assistant professor of biomedical engineering,has been awarded a five-year, $450,000 NSF CAREER award, titled “BoneInspiration in Research and Education.” Wilson will use the unique structureand function of bone to develop materials to stimulate bone healing andmodeling at the whole tissue, cell and molecular levels.Assistant Professor of Biomedical Engineering Jessica Ramella-Romanhas been awarded a $230,000 Early Career Award from the Wallace H.Coulter Foundation that will fund two years of research related to measuringoxygen levels in the retina of diabetes patients.Two other engineering faculty members, Phillip Regalia, professor ofelectrical engineering and computer science, and Peter Lum, assistant professorof biomedical engineering, recently received separate grants from theNSF and Veterans Affairs, respectively, totaling almost $700,000.Regalia has been awarded an NSF award for research totaling $120,000. Thethree-year grant, titled “MUCHO: Two problems in Multi-User Communicationsfor High Occupancy channels,” will study the specific problems created by theovercrowding of modern wireless devices sharing limited wavelengths.Lum has been awarded a three-year, $562,000 grant from the Departmentof Veterans Affairs’ Rehabilitation Research and Development Service to furtherdevelop neurorehabilitation abilities in stroke victims. The grant, titled“Extension of the MIME robotic system for stroke rehabilitation,” will workto improve arm function following a stroke.

cuaengineerBurns Faculty Fellowship Established to Support Junior FacultyA new faculty fellowship has been established through a generous donationof the Burns family — four of whom are graduates of the CUA School ofEngineering: Robert Burns (BME ’51) and his three sons Matt (BEE ’80),Mark (BEE ’82) and John (BEE ’85). This new faculty fellowship program isthe latest addition to the school’s faculty awards that aim to recognize andsupport excellent faculty. In 2001 the school established the Kaman’sfaculty excellence awards from an endowment of Charles H Kaman (B.A.E. ’40).Sixty years ago, in 1947, Bob Burns returned home from serving in WorldWar II, and enrolled in engineering classes at CUA on the GI Bill. He graduatedwith a Bachelor of Mechanical Engineering degree in 1951 and worked foran engineering firm in Washington, D.C. He helped the firm open a branchoffice in Philadelphia, where it was working on a project for the localairport. When the project was completed, Burns stayed to start his ownfirm in Philadelphia.Years later, when he began discussing college with his sons, Burns toldthem they could go to college anywhere they wanted — as long as it wasCatholic University. Today their family business, the Burns Group, is a multidisciplinaryengineering and design-build firm in Philadelphia with expertisein aviation and transit.The Burns family has been loyal to CUA during the last 60 years. BobBurns served on the Alumni Association’s Board of Governors and chaired adonor recognition society for the Annual Fund in the early 1980s. The familymembers have been generous annual donors to the university. In March2007, the family announced its desire to establish an endowment for a facultyfellowship program at CUA to support the research of junior faculty of theSchool of Engineering. In April 2007, Dean Nguyen, accompanied by MarkRoberts, development director, visited the Burns family at the Burns Group’sheadquarters in Philadelphia where they met Bob, Betty and Matt Burns andone of the dean’s former students, John Burns, who received an electricalMark Burns (BBE ’82), Matt Burns (BEE ’80), Dean Charles Nguyen and Mr. and Mrs.Robert Burns (BME ’51) at Commencement 2007. Not pictured is John Burns (BEE ’85).engineering degree in 1985. At the visit, the dean thanked the family membersfor their generous donation. Later the family members attended the2007 diploma distribution ceremony at the School of Engineering where thedean formally announced the inaugural of the Burns Faculty Fellowship programand gave the family an appreciation plaque. At a diploma distributionceremony that spring, Matt Burns presented award plaques to the inauguralBurns Fellows, John Judge and Zhaoyang Wang, who both are assistant professorof mechanical engineering.To be named a Burns Fellow, faculty members must submit a proposaloutlining their research plan, and be chosen by a selection committeeconsisting of the members of the school’s executive committee. The payoutof the endowment will be used to subsidize the expenses of the researchactivities of the Burns Fellows. The school expects to award up to two Burnsfellowships every academic year.Didion Honored with 2006 Engineering Distinguished Alumni AwardEngineering alumnus David Didion, B.M.E. ’63,M.M.E. ’63, D.Engr.’72, received the 2006Engineering Distinguished Alumni Award and washonored at a Homecoming luncheon sponsoredby the School of Engineering in October 2006.Dean Nguyen and David Didon, D.Engr., at the homecomingluncheonEstablished by the School of Engineering in 2004,this award has been used to annually honor worthyengineering alumni for their achievementsand contributions in their fields. Nominations forthis award can be made by faculty, students andstaff to the school executive committee thatmakes the selection and recommendation to thedean for his final approval.Dean Nguyen presented Didion with a plaquesignifying the award at the luncheon attended byabout 90 alumni, faculty, staff, students and CUAadministrators. After accepting the plaque, Didiongave a speech summarizing his experience withthe faculty of the School of Engineering and howhis CUA education has shaped his principles andcareer. Describing his reaction to learning of thehonor, he said “This is the best phone call Ireceived from the dean’s office.”Didion received his bachelor, master’s andDoctor of Engineering degrees from CUA, andthen served on CUA’s engineering faculty from1962 to 1971, before joining the National Instituteof Standards and Technology in 1971. He wasnamed a NIST Fellow in 1995 and retired fromfull-time service in 2002. He presently serves onthe CUA Mechanical Engineering Advisory Board.A private engineering consultant, Didion alsoteaches mechanical engineering courses forthe part-time Master’s degree programs atJohns Hopkins University and at the Universityof Maryland . He is a recipient of numerousawards, including the Hall Gold Award from theU.K. Institute of Refrigeration and the first GustavLorentzen Award from the International Instituteof Refrigeration. He is a Fellow of the AmericanSociety of Mechanical Engineering and theAmerican Society of Heating, Refrigerating andAir Conditioning Engineers.

cuaengineerCheckups Via CyberspaceFor low-income patients, gaining access to medical care can be difficult,but for low-income seniors, just getting to that place of service is often thehardest part.That’s why collaboration between the biomedical engineering departmentand the nursing school is bringing a nurse to their homes — virtually — andchanging the face of health care.Through a grant from the Department of Commerce, biomedical engineeringdepartment chair Binh Tran and Associate Professor of Nursing Kathy Buckleyhave spent the last two years shaping the idea of telehealth. Taking 25 patientsat a time, they focused on seniors at the Edgewood Community who sufferedfrom diabetes and high blood pressure. They provided seniors with a bloodpressure cuff, a weight scale and glucometer — all hooked up to a computerbox that attached to the phone line, and by extension, their very own nursingstaff. Patients take measurements every day that are automatically uploadedto a CUA server, where nurses can examine the data for any irregularities.On a weekly basis, nursing students gather patient’s data and make a“virtual house call” through a video phone.“The goal is to teach these patients to manage themselves and changetheir habits,” Tran says. The daily measurements and video phone interactionprovide constant feedback that keeps patients motivated. And for seniorswho often have no easy access to transportation and then, in many cases,spend hours sitting in a waiting room, having a virtual phone call is “almostKathy Buckley, Ph.D., responding to a patient through the Telehealth systemlike having a nurse on call,” Tran says, noting that if a patient calls with aquestion or problem, the nursing staff will respond within 24 hours.Patients enrolled in the program have their virtual nursing staff for threemonths before a new group of patients come into the program. The hope isthat after 90 days, patients can monitor themselves.Tran expects this telehealth system eventually to be the working modelfor larger outpatient care facilities that are able to serve large numbers ofseniors at one time.A Special Gathering Place: School of Engineering’s Alumni Garden Opens in Spring 2008Engineering’s Alumni Garden10 | cuaengineerAlumni, faculty and students will join Dean Nguyen and senior universityofficials May 2008 to dedicate the School of Engineering’s Alumni Garden. Thegarden is located on the exterior ground level of Pangborn Hall.“The Alumni Garden will be a special gathering place for our Engineeringcommunity. We envision an outdoor café, where students and faculty canrelax or study between classes,” said Dean Nguyen. “We will have wirelessInternet access, music playing through speakers in the background, andlighted walkways.”Crews began work last spring on the brick walkways and stone walls. Newlandscaping with trees and shrubs was planted. Wrought-iron tables and chairswere added this summer. Renovations will be completed in early fall.“The Alumni Garden will be a constant reminder to our students that greatthings are ahead of them,” Dean Nguyen said. “Our alumni are at the top oftheir fields. Some have become the ambassador to a foreign country, CEOof an international firm, a United States Navy Admiral, president of a university,and excellent faculty at other universities. We have named this garden inhonor of our alumni to celebrate their accomplishments.”The School of Engineering will inscribe the names of selected alumni andfaculty on the stone walls of the garden. Parents will also be able to honortheir son or daughter’s graduation by adding their child’s name to the “Wallof Achievement.”This is the latest capital improvement to Pangborn Hall, home to theengineering school since 1961. In 2003 Very Reverend David M. Connell,C.M., university president, dedicated a newly renovated Anthony J. ScullenRoom, named for a former dean. The Scullen Room is used for conferences,seminars and special events.

cuaengineerProfessors Offer Hope for Spinal Cord PatientsCUA assistant professors of biomedical engineeringJessica Ramella-Roman and Joseph Hidler havereceived a $150,000 grant from the Christopherand Dana Reeve Foundation to conduct medicalresearch in the care of persons with spinal injuries.Complications from pressure sores — one ofthe biggest problems facing spinal cord injuryvictims — led to the 2004 death of actorChristopher Reeve, who suffered a spinal cordinjury in 1995. One of the factors that Ramella-Roman and Hidler believe leads to pressure soresis a condition called autonomic dysreflexia, whichoften occurs in individuals with spinal cord injuriesin their upper back or neck.Since the lower extremities can no longercommunicate with the brain due to the injury,the body’s natural neurological response incorrectlyresponds to any stressful stimulation —even the need to urinate — by constricting theblood vessels in parts of the body below theinjury site. Because blood flow is reduced, lessoxygen reaches soft tissues such as the skin,ultimately leading to pressure sores.To investigate this phenomenon, Ramella-Roman has invented a novel fiber-optics-basedsensor that measures the oxygen levels in softtissue up to a centimeter under the skin. She andHidler will use the device on a group of spinalcord-injured subjects to measure the extent towhich autonomic dysreflexia is causing changesin skin oxygen levels and thus making the patients’skin more susceptible to pressure sores.The two professors’ previous research on onepatient in whom they artificially induced a singleepisode of autonomic disreflexia found that oxygenlevels dropped by as much as 40 percent in thelower extremities and blood flow dropped by asmuch as 60 percent.One of the possible results of the researchfindings will be to educate individuals with spinalcord injuries on perceiving and ultimately controllingepisodes of autonomic dysreflexia, whichmay result in the prevention of pressure ulcers.Center for Environment and Energy CreatedCivil engineering Professor Hsien Ping Pao thinkshe’s found the way to curb global warming, onebatch of fertilizer at a time.Last December, the School of Engineeringlaunched a new Center for Environment andEnergy under Pao’s direction. It is the formalizedunion of two colleagues who first started sharingnotes on the subject of global climate change 10years ago, when now Visiting Professor JerryShang worked for the U.S. Department ofEnergy. Shang now joins the center — andCUA’s faculty — as the center’s chief scientist.Shang and Pao are specifically interestedin the science of carbon sequestration, whichinvolves taking CO2 from power plants andremoving the carbon through scrubbing andconverting it into a water soluble fertilizer thateventually breaks down, leading the carbon tounderground aquifers, and eventually turning itinto limestone, a stable form of carbon. Shangcalls sequestration an environmental “win-win,”because it removes carbon from the air andprovides fertilizer.Pao refers to this form of carbon sequestration,as “Mother Nature’s Carbon Tax,” but says it hasnot been researched outside of China. SomeChinese fertilizer companies actually producecarbon to add to fertilizer, but Pao and Shang’smethod would utilize carbon that would otherwisebe polluting the air and adding to thegreenhouse effect.The center is pursuing funding from the UnitedNations and the World Bank, two internationalinstitutions that Pao believes will see the benefitof this system, especially for developing countriesthat rely heavily on agricultural production.The center will offer workshops as well asshort academic courses for students andoutside professionals and civil servants, inthe hope of educating those in the field aboutcarbon sequestration. Pao says the center willcollaborate with a professor at Western KentuckyUniversity, likely doing the bulk of their fieldwork using a smokestack in that region.The benefits of this form of sequestrationcould be huge, says Pao, who notes that morethan 50 percent of America’s power plants arefueled by coal, an available and cheap sourceof fuel. If Pao and Shang’s theory holds, “thenwe can still use coal,” Pao explains.The pair plans to expand the center in thecoming year, devoting funding and resourcesto proving their theory.fall2007 | 11

cuaengineerIEEE Student ChapterWhat do an X-box and an iPod have in common?Besides mass-consumer appeal, they both havefound their way into the creative designs of CUAelectrical engineers.The CUA student chapter of the Institute ofElectrical and Electronics Engineers had a busyacademic year, putting a new spin on a classicphysics experiment, working with U.S. veteransat the National Rehabilitation Hospital, and ofcourse, launching a few rockets.The Rubens’ Tube, also known as the standingwave flame tube, is a classic physics experimentfor electrical engineering students demonstratinga standing wave. It shows the relationship betweensound waves and air pressure. A length of pipeis perforated along the top and sealed at bothends—one seal attached to a small speaker, theother to a gas grill. Once the speaker is turnedon, pressure changes caused by the soundwaves will cause the flames to heighten in someareas and to lower in others. That’s where theiPod comes in. This year, IEEE students hookedthat speaker up to the mp3 player, watchingpressure changes brought by classic rock.IEEE students also helped turn entertainmentinto rehabilitation, working with CUA professorsin the Center for Applied Biomechanics andRehabilitation Research. The center has deviseda way to control a Microsoft X-Box video gamesystem so that soldiers with amputations cantrain their muscles in a fun, engaging manner.An artificial hand can be opened, closed ororientated by the amputee contracting theremaining muscles on his upper arm, but inorder to accurately control the artificial hand,a high level of skill is required to turn thosedriving muscles on and off. Through intensivetraining, people can learn how to turn muscleson and off in a highly efficient manner. CABBR,with the help of IEEE students, hoping tomake that intensive training a little moreentertaining — and giving veterans a chanceto enjoy a pastime so many Americans takefor granted: playing video games.

Seeing and recording an array ofimages, however, offers possibilities for visualinformation beyond the temporal. Department ofElectrical Engineering and Computer ScienceAssociate Professor Mark Miroztnik andAssistant Professor Scott Mathews, along with amultidisciplinary, multi-site team of researchers,have married the “fly’s eye imaging system” toa computerized camera system, a PracticalEnhanced Resolution Integrated Optical DigitalImaging Camera, dubbed PERIODIC. “Arrayimaging systems are an important step in thedesign of optical-digital integrated imagingsystems,” says Miroztnik. “They outperformsingle-lens systems while maintaining a thinform and a wide angle of view.”The PERIODIC camera system resembles acircuit-board sandwich, with the array of lenseson the front and green circuit boards in the middlecarrying information to a computer. Mirotznikexplains, “The optical sensor and software componentswork in concert to solve underlyingcomplex image registration and reconstructionproblems in near real-time and produce highdefinition, multi-layer images.”The prototype, funded by a DisruptiveTechnology Office challenge grant, greatlyimproves the resolution and dynamic range ofimagery, removes glare and performs spectralfiltering. It has moved the emerging “array imagingparadigm,” Miroztnik says, “toward systemsthat can maximize the information content ofimages relative to a set of prescribed imagingtasks.” Such tasks include iris recognition biometricsachieved through super-resolution, glarereduction through polarization, extended depth offocus by changing the focal point of lenses andcombining those images, and enhanced dynamicrange through the use of neutral density filters.Miroztnik and his team are particularly gratifiedby application of the technology to burninjury assessment. “The most critical factorsdetermining whether or not burn patients recoverare rapid assessment of the degree of burnsand quick, appropriate treatment,” saysMiroztnik. Severe burns destroy subcutaneousblood vessels, decreasing the flow of blood totissues, which can result in the death of tissueand loss of limbs as well as significantly increasingthe chance of life-threatening infection.“Using multi-spectral imaging through a 1650 nmspectral filter, we can accurately measure bloodoxygen levels in a patient’s skin and give doctorsthe rapid evaluation of the extent of tissue damagethey need to initiate appropriate treatment.”“With the PERIODIC camera system, we’veopened the door on the design and versatility oflenslet array systems,” Miroztnik concludes, “butwe’re looking forward to considering many moreaspects—the use of diffractives, GPU integrationand the difficult nonlinear numerical optimizationproblem of joint approaches for registration andreconstruction.”12 | cuaengineer

cuaengineerA Capitol Idea for Repairing FrescoesOverlays of data on images of walls for the Capitol buildingfresco deterioration projectProfessor Vignola working on the Capitol building frescodeterioration detection projectMost Americans may not realize this, but you don’t have to travel to Italy toview an original fresco. More than 100,000 square feet of space is coveredwith the plaster artwork in the nation’s Capitol building, and one CUA professoris helping to ensure those frescoes are preserved for future generations.Mechanical engineering Assistant Professor Joe Vignola is using somevery state-of-the-art laser technology to help preserve the centuries-old art.Frescoes, a type of mural painting that dates back to the pre-Christian era,are created by mixing dried pigment into wet plaster. They can last forthousands of years without fading in color, but are vulnerable to plasterfailure, water damage and decay.For centuries restoration teams have tried to repair frescoes, often byinjecting plaster directly into the frescoes to bond them back to the wall.Restoring a fresco is relatively easy, says Vignola. Determining which areasof a massive fresco are vulnerable, on the other hand, can be the trickyFor ASME Students, a National ClassroomASME students tour Capitol Power plant.Professor Vignola working on the Capitol building frescodeterioration detection projectpart. Historically, restoration teams have relied on a “tapping and listening”method, detecting loose areas by listening for a hollow sound — anarguably subjective system.That’s where Vignola’s laser comes in. By bouncing laser beams off thefresco surface, Vignola can get a computer reading that detects vibration ina fresco. The degree to which a given area of plaster resists motion givesan extremely accurate reading of a fresco’s structural integrity. The greaterthe vibration, the likelier that a fresco is about to fail.Vignola was contacted by the U.S. Capitol curator five years ago and hasbeen assessing portions of the capital’s frescoes ever since. He estimatesthat so far he’s covered about 7,000 square feet of fresco, thanks to a grantfrom the architect of the Capitol. But there’s still quite a bit of plaster left tocover and Vignola plans to keep looking for trouble spots.Mechanical engineering students know firsthand that Capitol Hill is full ofhot air. Last fall, members of the student chapter of the American Society ofMechanical Engineers toured the Capitol Power Plant, observing systemssuch as boilers, heat exchangers and pollution control systems. The purpose ofthe visit was to examine how theoretical knowledge of mechanical engineeringapplications is put into practice.But why stop there when things are just heating up?Interest from the visit was so high that club organizers scheduled afollow-up trip to the Potomac Generation Station in Alexandria, Va., duringthe spring semester so that students could examine a full-scale city powergeneration station in action.ASME also took to the skies, visiting the National Air and Space MuseumSteven F. Udvar-Hazy center located at the Dulles international airport. TheUdvar-Hazy is unlike most other museums in that every item exhibited isthe real thing — not merely an artist’s rendition or a display model.Students were able to see up close some of the most influential aircraft andaerospace related memorabilia from the last 100 years, including the SR-71, the Space Shuttle and jumpsuits from the U2 spy plane missions.fall2007 | 13

cuaengineerJunior electrical engineering student Brandon Gooddemonstrates the Train and Play systemTraining to Play, Playing to TrainEverybody knows that kids who play video gamescan move a mouse or joystick like lightning. Themotions themselves may be repetitive, but whocares? It’s fun.What if someone brought the fun of a videogame to the repetitive tasks of physical therapy?With a start-up grant of $8,500, electrical engineeringAssistant Professor Scott Mathews, incollaboration with the National RehabilitationHospital, is doing just that: exploring ways tobring the fun and challenge of video games to therepetitive tasks that comprise physical therapy.For amputees—especially soldiers returningfrom Iraq—facing the prospect and promise oflearning to use technologically advanced prosthetics,the prospects look a little brighter.“We call it ‘train and play,’ ” says Mathews,attaching electrodes that used to be connected toa joystick to his biceps and triceps. “Amputeesmust retrain remaining muscles to control thefunctions of lost muscles through the prostheticinterface. Instead of hours of boring repetition,we want them to be able to just plug into thevideo and have fun.”Mathews, who designed the circuitry, flexeshis arm, sending out an electrical impulse thattravels down the wires to the X-box monitor. Onscreen a box moves from left to right, up anddown, until Mathews succeeds in placing it inthe open space and goes on to the next one.“The electrode is reading the muscle activity inwhat would be an amputee’s stump,” he says.“It’s not easy to learn, but once the muscleshave been trained, the prosthesis can be fitted.”The technology has utility not only foramputees, Mathews says. “We think this type oftherapy could help many people with all kinds ofcognitive/muscular issues—children with attentiondeficit and hyperactivity disorder to helpthem learn to focus; people with cerebral palsy,to train them to flex specific muscles and gainsome control over their movements.”The next step for the train and play model is aclinical trial. Then Mathews hopes to tap fundingto create more refined circuitry that controlsmore complex video games to help amputeesgain fine motor control. Says Mathews. “Wewant to move beyond button pushing to morecomplicated motions. For amputees holding acup of coffee is a miracle.” A miracle worthworking—and playing—for.Hovercraft to Uncover LandminesMechanical engineering and computer science seniors usually look forwardto one key rite of design-passage: creating and building a hovercraft. Thisyear, mechanical engineering Assistant Professor Joe Vignola gave hisstudents an additional challenge: use their powers for good.“I felt very strongly that we needed to focus senior design on doingsomething useful,” Vignola says.This year, design students were asked to conceptually develop a prototypehovercraft for autonomous detection of landmines. The hovercraft would notbe radio controlled, but rather it would make its own decisions and navigateand survey on its own. This was the first time that students were asked todesign a hovercraft that was not manually operated by a driver.“Landmines are an atrocious problem in the Third World,” Vignola says,often in places that haven’t seen active warfare in decades. It’s not armedforces that suffer, Vignola notes, but rather local children and villagers whocan be severely maimed or killed by stepping on an old landmine.Students were asked to focus solely on the structure of the hovercraft,not on developing new landmine detection technology. The primary goal ofthe design exercise was to create a new type of platform that could carryexisting technology into areas that would be hazardous for humans to ventureinto. The technology operating inside the hovercraft would find suspiciousburied objects and mark them with a GPS signal.The project to build this prototype, that is a collaboration betweenmechanical engineering and computer science, has been an important one,says Vignola, noting that the days of mechanical engineers working in avacuum no longer exist.Seniors finished a workable prototype and next year’s design class willpick up where the previous group of designers left off, beginning to buildthe structure. They’ll have some money to work with: a $62,000 grant fromthe U.S. State Department Office of Humanitarian Demining. The rising seniordesign class will spend the fall assembling and testing the hovercraft, inadvance of a scheduled demonstration in March at a military testing facility.Image of a Hovercraft prototype14 | cuaengineer

cuaengineerStealth Senior DesignTwo CUA electrical engineering seniors may have found a solution to a sophisticated electromagneticproblem that has long perplexed engineers. They hope to have those findings published in a peerreview journal this year.Daniel Brosius and Christopher Ratto decided to take a closer look at frequency selective surfacesas part of their electrical engineering and computer science year-long senior design project.The phrase “frequency selective surfaces” may sound like engineering jargon, but it is at the heartof defense technology. Military planes and ships use extensive radar to communicate with their headquarters,gather information and detect enemy coordinates. But this radar makes an otherwise stealthyplane or naval ship easily detected by an enemy’s own radar. Frequency selective surfaces allow theship’s antenna to operate and its radar to function, while deflecting enemy radar to avoid detection. Inother words, the ship or plane is encased in a surface material that selectively lets only certain, desiredfrequencies pass through.By doing so, says electrical engineering Assistant Professor Scott Mathews, “You create a plane orship that is nearly invisible to enemy radar, but still has fully functional radar.”Engineers solved the “forward” problem of selective surfaces years ago. They are now able to determinewhat frequencies will pass through a given surface’s geometry—as well as what frequencies thatgeometry will deflect or absorb. And so they can build a particular shape with those known variables inmind. But working from the other direction—taking a known radar and creating a geometric patternbased on that radar—has long eluded engineers.“Ships designers want to say ‘Here’s the radar that my ship uses. What pattern do I need to makemy ship invisible and make my radar still work?” say Matthews. “That is the inverse problem and noone’s completely solved it yet.”Brosius and Ratto set about to solve that far more complex inverse problem: Given a desired electromagneticperformance that you want to allow through, what shape or what geometry must be created toget that performance?Brosius and Ratto used an iterative method employing the Mat Lab program and an algorithm forsolving the forward problem, known as the “Periodic Method of Moments” or PMM. They started bymaking a random guess as to the desired geometry and then entered the guess into the PMM.Depending on the outcome, they continued making changes to the geometry, each one bringing themhopefully closer to the sought-after result. By making modifications that brought them closer to theirend goal, the pair eventually created the geometry that matched the desired frequency. They then builtseveral frequency selective surfaces and measured their electromagnetic performance to see if theactual results matched up with the desired performance.It did.“This work is really, really sophisticated stuff,” says Matthews. “They’re two of the brightest studentswe’ve had come through here in a long time.”Mathews, in collaboration with Associate Professor Mark Mirotznik, receives funding from the Officeof Naval Research to study frequency selective surfaces.Nagel FoundationFosters BiomedicalInnovations2007–2008 Nagel Scholars with Dr. and Mrs. Dan andIngeborg SoberNine CUA biomedical engineers have beenselected as Nagel Scholars for the 2007–2008school year, an honor which, for the lastdecade has been synonymous with enterpriseand academic excellence.Since 1998, the CUA biomedical engineeringdepartment has received generous support fromthe Edward M. Nagel Foundation to recognizeand offer financial support to the program’s topscholars. To date, the foundation has providedCUA — one of just six universities in the nationaffiliated with the organization — with morethan $500,000 in scholarships. Nagel Scholarsare required to have demonstrated outstandingacademic achievement, service and communityinvolvement. They are also chosen for theirentrepreneurial acumen and industry in thefield. The average GPA among the comingyear’s designated scholars is a 3.78.The 2007–08 Nagel scholars are: CaitlinMatyas (’08), Bradley Miller (’08), ThomasGiuliani (’09), Emily Casadaban (’09), TheresaMurray (’10), Megan Jamiokowski (’10),Katherine Rucky (’10), Jenna Graham (’11),Patrick Noonan (’11). Scholars receive a $5,000scholarship for each of their four years of undergraduatestudy.Recent graduates of the Nagel scholar programhave found places of distinction in both doctoralprograms and industry. For example, StephanieKennedy, a 2003–2005 Nagel scholar, is attendingDuke University on full academic scholarship,where she is earning a Ph.D. in biomedicalengineering in the area of biomedical imaging.Lindsay DiRomualdo, a 2003–2004 scholar, isnow working for Medtronic Corporation in thearea of biomedical implants.fall2007 | 15

cuaengineerBiomedical Design Center Keeps GrowingBiomedical ConferencePuts CUA on the MapThis past spring, the biomedical engineeringdepartment hosted the Southern BiomedicalEngineering Conference at CUA — the firsttime CUA has hosted such a gathering. Eightyengineers, academics and students participatedin the conference, and graduate or undergraduatestudents comprised about half of thatnumber. Faculty and members of industryand government, including speakers fromJohnson & Johnson and the U.S. Food andDrug Administration, attended the three-dayconference. Of the attendees who had submittedabstracts in advance of the conference, 50presented their papers, which will be publishedin a volume in the coming months.In 2003, CUA’s biomedical engineering created theBiomedical Engineering Design Center in PangbornHall to answer the need for a dedicated designspace for biomedical engineering students to conductsenior design projects. A fabrication spacewas installed, along with three work stations fordesign teams.In the past four years, the number of CUA biomedicalengineering students has nearly doubled,and the design center itself has expandedtwice more to accommodate more design teamsand the current 65 undergraduate biomedicalengineering majors. The center now featureseight work stations, each capable of supportingdesign teams of three to four students. Eachworkstation is equipped with state-of-the-artequipment for computing design, fabrication andproto-typing, and testing equipment.For students in their junior and senior yearcompleting design projects, and for Binh Tran,the department chair, having a fabrication spaceinside the renovated studio was critical. Transays he believes biomedical engineers need tolearn how to build models, not just create adesign in a computer and then send it off to amachine shop to be constructed. So now designstudents have access to drill bits, lathes, bandsaws and raw materials and are expected tocreate a 3-D working proto-type of their designby the end of a one-semester design studio.Tran also sees this studio as a means to bringCUA into the forefront of the nation’s biomedicalengineering programs.“We want to be competitive in national designcompetitions,” Tran says. “These renovationshave enabled us to participate in those competitions.”It has also better enabled the school tobring those competitions and conferences toCUA’s campus. This year, CUA hosted a biomedicalconference (see sidebar) bringing students,professors and professionals from across thecountry for several days of discussions andpaper presentations on contemporary topics inbiomedical engineering.Given the steady growth of the biomedicalengineering department, the current studio mayneed to be expanded yet again before too long.But for Tran, those are welcome growing pains.CUA Engineers Place Third in National Design Competition.Two CUA biomedical engineering students aim to take the heavy lifting out of the medical profession —and they are earning national accolades along the way.The two students set out to find a safer, more efficient way to transport patients from the hospitalbed to various testing areas as part of their junior design project two years ago. Transferring patientswho are immobile or obese from hospital bed to gurney to MRI table can place a physical strain onhealth care workers and risk injury to the patient — not to mention take up critical time. The students,Afshin Nabili and Roland Dinga, continued the project the following semester as part of an independentstudy under the direction of department chair Binh Tran.After finishing the design and prototype, they entered the project, “Patient Imaging TransferringSystem (PITS),” in the Accessible Medical Instrumentation National Student Design Competition. Nabiliand Dinga’s design was judged against more than 50 designs from around the country, most of themsubmitted by seniors who had spent two design semesters completing their final product. The pairplaced third in their category, patient transfer-and-positioning device, and earned a $500 prize.The goal was to design a system in which the patient never has to get out of bed — technically.This could be achieved by designing a new kind of gurney with a detachable surface. The top portionremains under the patient whether they are in a hospital bed or on the gurney. The patient can be slideasily from bed to gurney and locked into place. The PITS device also can be converted into a wheelchairfor better transport. Once at the lab, the removable portion slides from gurney to testing table.The students designed the material to be compatible with MRI equipment.“There’s definitely a gap in the marketplace,” says Tran. “There’s nothing like it out there right now.”Which is why Tran is in the process of getting the design patented. The patent disclosure is currentlybeing reviewed by the university’s patent committee, which will make a recommendation soon as towhether to sponsor the patent application.16 | cuaengineer

Concrete Canoe Team In ActionEach year students from CUA’s student chapter of the American Society ofCivil Engineers, join students from universities around the country in theConcrete Canoe Competition.Students build their vessels out of concrete, reinforced according tocertain preset rules and challenging specifications that change every year.Long enough to carry four, the canoes must pass a swamp test beforestudents are allowed to take it out in deeper water. In this test, thecanoes must continue to float after being intentionally filled with water.The concrete mix must be sufficiently light without the addition of anybuoyant materials such as Styrofoam. In addition, the concrete mustalso be strong enough to survive several in-water competitions carryingup to four students.Engineering Week 2007Among the student projects demonstrated during Engineering Week2007, the electrical engineering students pictured below used theancient—a flame—and the modern—a popular mp3 player—to bringa classic electrical engineering experiment to life. They created a‘Ruben’s Tube,’ also known as the standing wave flame tube, whichshows the relationship between sound waves and air pressure. For a fullexplantation of this experiment see page 12.As always, the hard-working students were more than ready at theend of the week to kick up their heels at the annual ball, as the onespictured below seem to be doing quite well. Students put on the dog fordancing, conversing and dining at Maggiano’s, a D.C. Italian eatery. Allwork and no play? No way. At the ball Dean Nguyen announced thatelectrical engineering was the winner of the Engineer’s Week 2007.Engineering week IEEE Ruben Tubes Project2006–2007 concrete canoe team building their craftEngineering week ballTwo hardy canoeists test out the boat’s ease of use, speed under paddle and maneuverabilityfall2007 | 25
