SMS Institute of Technology, L ucknow Department of Electronics & Co mmunication feel about retina scanning sec urity measures being used? Consider these factors carefully before your decision. WHERE IS RETINA SCANNING USED? Retina scanning is mainly used for places that require a high level of security, for instance power plants, military installations & other secure government sites. Retina scan computer access is sometimes used for computers that have top-level security informations. A number of other com panies are starting to use the t echnology, including banks (this pla ce the technology in ATMs) & prisons. THE FUTURE OF RETINA SCANNING The future impact of retina scanning is likely to be felt mostly in the medical field, rather than the security field. Retina scanning can hel p doctors diagnose a number of diseases & may help many diseases be diagnosed much earlier than they otherwi se would be. Scientists are currently researching ways in which retina scanning can help medical professionals & there is likely to be some breakthrough in the future. There is also talk of having nationwide screening services. In term of security, there will also be improvement in retina scan technology. These improvements are likely to achieve a quicker reading t ime if the retina & making the retina scanner more user-friendly. Retina scanning will probably start to be used by a wider range of companies & corporation that do not necessary have high security needs. However, this will probably bring up issues of privac y & intrussiveness and as retina scan security becomes more prevalent. Hyper threading technology in core processors Modern processors can handle only one instruction from one program at any given point of time. Each instruction that is sent to the proce ssor is called a thread. Today's Intel Hyper-Threading Technology (Intel HT Technolog y) delivers thread-level parallelism on each processor, resulting in more efficient use of processor resources, hi gher processing output and improved performance on multi-threaded software. An Intel processor and chipset combined with an OS and BIOS supporting Intel HT Technology allows us to: ‣ Run demanding applications simultaneously while maintaining system responsiveness to the opti - mum. ‣ Keep systems more secure, efficient, and manageable while minimizing impact on productivity. ‣ Provide room for future business growth and new solution capabilities. The figure 1 above tells us about the usage of different cores o f the processor that take up multipl e threads or instructions at one go and operate upon them producing th e required output. This is a pro minent feature of Intel Core-i3 processor. The figure 2 tells us about th e usage of the same 4 cores of t he single processor but this time each core can access multiple threads, thus having an advantage over the C orei3 processor. A typical feature of Corei5 & i7 processors. TURBO BOOST TECHNOLOGY The new Intel's Turbo Boost Technology covers all our problems related to Fast System Booting, Processing & Termination. This new technical complexity developed by Electroni cs & Micro processing Engineers at the Intel Corporations, has revolutionized the modern Tech Era and has helped a lot with Speedy and Reliable Multitasking Processing. TDP- THERMAL DESIGN POWER Thermal Design Power merely indicates the power limit or percentage usage of core(s) of a processo r that are currently into operational state in form of bars as shown above. By the figure, it's quite clear that in the Previous Generations of Processing the Active Cores had n o advantage of having the Processi ng Power Sharing from the Idle Co res. But in the Core-i5 &i7 process ors, if Aman Srivastava EC - III year the Active Cores are operating then the Idle Cores provide a Shari ng of the Processing Power to them resulting in ULTRA HIGH SPEED COMPUTA- TION, QUANTIZATION, PROCESSING AND LOTS MORE!! ADVANTAGES The major advantage of Hyper threading moulded or amalgamat ed with the Turbo Boost Technolog y is that the performance of the sy stem increases to about five to ten times yet with a negligible increase in the power or energy consumption due to the use of Nanotechnology that allows the fabricators to hang over with millions of transistors on just a 45nm chip. Rest is the fact that takes care of the performance that at Nanoscale, the behaviour of the materials abruptly changes and thus at the stake of Maximum Performance and Energy Efficiency along with the Mini mum Heat Dissipation the new Core processors are not just Faster, t hey are Smarter too!! 14 Electronics Spectra, 2010
SMS Institute of Technology, L ucknow Claytronics : Turning dream into real Department of Electronics & Co mmunication Sudhanshu Singh EC - III year Transmission and reception of sound energy by telephone was followed by a revolution in electronics and its digitalization. Pictures along with sound were then transported successfully from one place to another along with miniaturization of electronics. Such developments inspire scientists and engineers to think about human teleportation. Teleportation is the transfer of matter from one place to another instantaneously, either by paranormal means or through technological artifice. Matter teleportation, however, is still a day dream, but along these lines researcher have come up with a new science called Claytronics. The idea is to create a small robot of a few millimeters which can organise itself into a shape that is determined remotely. Claytronics is an emerging field of engineering, drawing on nano technology and computer engineering. Claytronics or programmable matter refers to an assembly of tiny components called claytronic atoms or catoms, which could assume the form of any object, depending on the programs controlling the Claytronics. This term also refers to the art of making clay caricatures of public figures, begun in 1996 by an Indian Charuvi Agrawal. CLAYTRONICS is a concept that combines nanotechnology and modular programmable robotics to create what is also called programmable matter, programmable grit, dyn amic physical rendering or synthetic reality. Very small components, called claytronic atoms or catoms, have the ability to move and morph into shapes controlled by a communication network. Claytronics is a form a progra m- mable matter that takes the concept of modular robots to a new extreme. One of the primary goals of Claytronics is to form the basis for a new media type, pario. Pario, a logical extension of audio and video is a media type used to reproduce moving 3D objects in the real world. Claytronics is a name for an instance of programmable matter whose p rimary function is to organize itself into the shape of an object and render its outer surface to match the visual appearance of that object. Clayt ronics is made up of individual components, called catoms—for Claytronic atoms— that can move in three dimensions (in relation to other catoms), adhere to other catoms to maintain a 3D shape, and compute state information (with possible assistance from other catoms in the ensemble). Each catom is a selfcontained unit with a CPU, an energy store, a network device, a video output device, one or more sensor s, a means of locomotion, and a mec hanism for adhering to other catoms. A Claytronics system forms a shape through the interaction of the individual catoms. For example, suppose we wish to synthesize a physic al “copy” of a person. The catoms would first localize themselves with respect to the ensemble. Once localized, they would form an hierarical network in a distributed fashion. The hiera rical structure is necessary to deal with the scale of the ensemble; it helps to improve locality and to facili tate the planning and coordination tasks. The goal (in this case, mimicking a human form) would then be specified abstractly, perhaps as a series of “snapshots”. or as a collection of virtual deforming “forces”, and then broadcast to the catoms. Compilation of the specification into local actions would then provide each catom with a local plan for achieving the desired global shape. At this point, the Catoms would start to move around each other using forces generated on-board, either magnetically or electrostatically, and adhere to each other using, for example, a nanofiber-adhesive mechanism. Finally, the catoms on the surface would display an image, rendering the color and texture characteristics of the source object. If the source object begins to move, a concise description of the movements would be broadcast allow ing the catoms to update their pos itions by moving around each other. T he end result is the global effec t of a single coordinated system. The core concepts in Claytronics are hardly new; from science f iction to realized reconfigurable rob ots to proposed modular robots, scien tists and writers have contemplated the automatic synthesis of 3D objects. However, technology has finall y reached a point where we can for the first time realistically build a system guided by design principles which will allow it to ultimately scale to millions of sub-millimeter catoms. The resulting ensemble can be viewed as either a form of programmable matter suited for implementing pario or as a swarm Fig. 1 15 Electronics Spectra, 2010
