Dr. Suwan Runggeratigul
Assistant Professor
B.Eng. (1 st Class Honors) in Electrical Engineering, Chulalongkorn University, Thailand
M.Eng. & D.Eng. in Electronic Engineering, University of Tokyo, Japan
Areas of Specialization: Communications, Networks, Metaheuristics.
Research Interests:
WDM Network Design
Wavelength division multiplexing (WDM) is a
promising technology for supporting future broadband
networks, which are capable of providing high speed
multimedia services. The key concept of WDM is to
let users share a large amount of bandwidth in an
optical fiber by using different wavelengths. Important
design issues in WDM networks are the node
placement optimization, the routing and wavelength
assignment, and the wavelength converter
placement. Novel methods are needed to efficiently
solve these design problems.
Communication Network Design by Metaheuristics
Since communication network design is generally a
hard optimization problem with a very wide search
space, there is an enormous effort to apply modern
heuristic search methods (metaheuristics) to network
design problems. The well-known and commonly
used metaheuristics in the literature are simulated
annealing, tabu search, ant colony optimization, and
evolutionary algorithms including genetic algorithms
and memetic algorithms. Interesting research topics
include the study on the application of metaheuristics
and the performance comparison among several
methods for the solving of network design problems.
Dr. Toshiaki Kondo
Lecturer (Joined SIIT in October 2004)
B.Eng. in Mechanical Engineering, Tokyo Institute of Technology, Japan
M.Eng. in Information Processing, Tokyo Institute of Technology, Japan
M.Eng. in Image Processing, The University of Sydney, Australia
Ph.D. in Image Processing, National University of Singapore, Singapore
Areas of Specialization: Digital image processing, such as feature detection and segmentation in 2-D and 3-D.
Computer vision, such as depth estimation and motion estimation. Pattern recognition, such as human face
recognition.
Research Interests:
Digital Image Processing (especially Medical
Image Processing)
Feature detection and image segmentation are the
primary areas of my research interests. “Analysis of
3-D maxillofacial image data” is the title of my
doctoral dissertation, which focused on the analysis of
the human dentition and jawbone for orthodontic
treatment and surgery. The extraction of anatomical
features in retinal images is one of my recent
research topics.
