MESSAGE FROM

The Department HeadThe history of the Electrical and Computer Engineering Department spans over 100 years,

distinguishing itself as one of the oldest and strongest branches of Drexel University.

Drexel’s earliest records indicate that the first engineering student was enrolled in 1896 in

the Electrical Engineering Department, and our department awarded the first engineering

degree in the early 1900s. In recent years, we have witnessed a tremendous amount of

dynamic growth. Nine new tenure-track faculty members have joined our department dur-

ing the past few years, and we anticipate that this expansion will continue. We have

initiated several new master’s degree programs in Telecommunications Engineering,

Computer Engineering, and Software Engineering. These programs, combined with the

M.S. and Ph.D. programs in Electrical Engineering, provide our graduate students with

diverse and state-of-the-art degree options in some of the most exciting and rapidly

expanding technologies that are fueling our economy. We have seen a recent surge in

research awards and expenditures, and in FY 2000 the ECE Department achieved $9 mil-

lion in total research awards. This type of dramatic increase in research funding will

undoubtedly create many new opportunities for our faculty and graduate students.

Our faculty members enjoy excellent national and international reputations. They belong to

prestigious professional organizations, and they have received various national awards.

For example, we have a member of the National Academy of Engineering, twelve IEEE

Fellows, three NSF Presidential Young Investigator/Presidential Faculty Fellow awardees,

and four recent NSF CAREER awardees. The ECE Department is internationally recognized

for its research in a number of key areas, including telecommunications, information net-

working, computer architecture, computer networks, imaging and signal processing,

microwave and lightwave engineering, power systems engineering, controls, robotics,

neural networks, ultrasonics, and biomedical engineering. The department also houses

several nationally recognized research centers: the new Center for Telecommunications

and Information Networking, the Center for Microwave/Lightwave Engineering, the Center

for Electric Power Engineering, the Fiber Optics and Photonics Manufacturing Engineering

Center, and the Imaging and Computer Vision Center.

I invite you to visit us in person or via the web at www.ece.drexel.edu. Please feel free to

contact me or other members of the ECE faculty for further information.

With my best wishes,

ProfileDr. Cohen’s research interests are in computer vision, medicalimage processing, and applied stochastic processes.

Brain Mapping: The problem of registering data obtained fromdifferent modalities (CT, MRI, PET) is of paramount importancein finding anatomical dysfunctional regions in the brain and incomparing different individuals. The problems of brain size vari-ability, incomplete data sets, and non-aligned and transformeddata that are routinely encountered should be addressed. Thisnecessitates the use of invariant theory for modeling and align-ment. This work is sponsored by NIH under a resource centergrant. The work also extends to cross-modality registration of MRI with nuclear imaging for improving diagnostic cancer detection in the breast. Sponsored by a Drexel/MCP Hahnemannsynergy grant.

Analysis of Ultrasound Images for Tissue Characterization inHuman Organs: This work expands the limit of contemporaryclinical ultrasonography by employing a quantitative tissue (liverand breast) characterization method that assists the radiologist byextracting structural tissue information not seen on the B-scanimage under examination. A decomposition approach for the RFecho into the coherent and diffuse component, related to theresolvable and unresolvable scatterers in the liver and breast struc-ture, respectively, is used for estimating structural parameters ofthe liver and breast. For example, the average spacing of the liverlobules, the energy of the resolvable scatterers and unresolvablescatterers in the tissue, etc. Preliminary results on single parame-ters of the liver and breast tissue showed good discriminatingpower between cancerous and normal liver and breast tissue andbetween malignant and benign breast tissue using ROC analysis.Sponsored by the National Cancer Institute and NIH.

Face Modeling and Recognition: A new scheme for 2D facerecognition from 3D structure database is introduced. The 3Dfacial structure allows for the synthesis virtual image to bematched with the test image for face identification. The synthesisalgorithm is fast and generates realistic faces. It does not require alarge number of example views in the database and can identify aperson in the database from one or more arbitrary image view(s).Pose estimation is achieved through the use of a large set of fea-tures on the face and a distance map computed as a lookup tablefor a set of points and curves extracted from the test image. Amechanism is proposed to fuse the geometric-based face classifier


(the residual distance map error) with the intensity-based classifierfor achieving classification rates that surpass those obtained byeach classifier on its own. The fusion of these two metric allows forrobustness: to slight changes in facial expressions, which mightaffect locally some of the geometric features but does not greatlyaffect the intensity image; and to slight variations in illuminationconditions, which would impact the intensity metric but not thegeometric one.

ProfileBiomechanical and electromyographic correlates of step-down inhumans: The purpose of this project is to determine which sensoryparameters dominate the selection of the motor programs for step-down (toe first stepping) or ambulation (heel first stepping).Healthy subjects step from variable heights onto an instrumentedwalkway. Data is collected on the height of the step-down, the forcewith which the subject contacts the walkway, and muscle activity inorder to characterize the motor program selected by the subject.

Postural sway and its effects on stability of stance in the elderly:

The goal of this project is to develop a model of quiet and perturbedstance which will provide the appropriate measures needed to iden-tify people who are incipient “fallers.” Measurements of posturalsway are performed on an instrumented, movable force plate.

Cervico-ocular reflex (COR) and vestibulo-ocular reflex(VOR) effects on eye stability during passive movements: The pur-poses of this project are to determine whether the COR can substi-tute for a defective VOR in stabilizing the eyes during head andbody movements. This goal is one milestone in the long range aimof defining the influence of sensory systems on locomotion. Theexperiments involve testing of humans in a darkened environmentduring quiet standing on a platform which can be moved in a con-trolled manner. The subject’s head can be moved separately so thatangular perturbations can be applied independently to the headand neck.

Neural network description of plasticity in motor systems: Adescription of specific motor system plasticity using the frame-work of non-linear dynamical equations offers the possibility ofuseful models when considering large neuronal systems.

Profile Dr. Fromm investigates the following topics: bioinstrumentation,sensors, biotelemetry, and innovations in engineering education.

An Enhanced Educational Experience for Engineering Students,E4: This involves a major effort to evaluate and restructure theeducational experience of undergraduate engineering majors at thelower division level. Drs. Fromm and Quinn inaugurated the pro-gram. It is supported jointly by NSF and Drexel University. Theprogram covers a five-year period and involves a large number offaculty, staff, and students of diverse backgrounds and interests. Inaddition to enhancing the University’s program, this research anddevelopment is also intended to serve as a national model.

Gateway Engineering Education Coalition: Dr. Fromm is thePI for the Gateway Engineering Education Coalition, a collabora-tive program of 10 institutions that is headquartered at DrexelUniversity and supported by the Engineering Directorate of NSF.The Coalition is an extension and an expansion of the E4 Pro-gram, now institutionalized as “The Drexel Curriculum.” Itfocuses on course content, the development of full human poten-tial, and the emerging engineering professional of the 21st century.The objectives emphasize engaging students in engineering fromthe day they matriculate; making the study of engineering moreattractive, exciting, and fulfilling; developing students as emergingprofessional leaders; increasing the diversity of academic back-grounds and the percentage of women, minorities, and the dis-abled; and drawing engineering faculty to a dedicated investmentin the teaching of undergraduate students.

Instrumentation, Biosensors, Biotelemetry: The understandingof physiolgical systems and functions is greatly enhanced if onecan conduct studies in living systems while the multitude of natu-rally interacting forces are in operation. Projects involve the devel-opment of micro miniature sensors and transmitters for varyingpurposes and studies. The work is generic in character intendedinitially for the rigorous internal environment of physiologic sys-tems but is also applicable to other engineering investigations. Thelaboratory’s design and development of novel sensors and chroni-cally implantable transmitters have been applied touch studies asthe quantification of contractility of the oviducts in sub-humanprimates, relationships of such contractility to hormonal statesand therapies, the wave patterns of contractility, and their tempo-ral as well as spatial relationships.

ProfileDr. Kalata’s research examines the areas of stochastic and adaptivecontrol theory; estimation, identification, and decision theory;computer control and system design. His current projects involvereal-time control of stochastic processes that not only involveimplementation of Kalman Filters but also adaptive strategies forself-tuning and disturbance accommodation.

Real-time Control of Stochastic Systems: Real-time hardwarecontrol systems inherently have disturbances that require not onlynoise filtering but also disturbances accommodation controlstrategies in which the disturbances must be identified, filtered,and accommodated. The stochastic control algorithms are imple-mented via real-time computer control systems.

Practical Implementation of Kalman Filters: Kalman FilteringTheory has been one of the most revolutionary additions to Con-trol Theory. However, its complexity increases as the noiseprocesses become biased, colored, and correlated. Restructuringthe filtering problem removes the algorithm complexity and leadsto the simplest form of the Kalman Filter, which can be used in awide class of filtering problems.

Education B.Sc. E.E., Tel Aviv University 1977M.S. E.E., Drexel University 1985Ph.D., Drexel University 1987

ProfileDr. Kam’s research interests are in team decision and team estima-tion for multisensor architectures. These architectures combinedata and opinions that are supplied by many different agents.Their operation requires not only the monitoring of the externalenvironment that they try to sense, but also the monitoring of thevarious agents that supply them with data.

He applies his studies in team decision theory to mobile robotsand pattern recognition. Over the years, his lab has built severalmobile robots (tracked and wheeled autonomous vehicles andlegged machines), and they are used to study multi-sensor mapmaking, path planning, and vehicle control. He has studied andwritten about several complementary approaches to these tasks.The ultimate goal is to combine the strengths of several differentapproaches into one high-performance and robust architecture.Following a similar philosophy, he has been working on severalinteresting problems in pattern recognition, particularly in detect-ing intrusions in computer systems and administering multi-usercomputer networks (dynamic coalitions).

He recently started looking into supervisory control of dis-crete-event systems. He was motivated by problems in decentral-ized control of power systems that emerged from deregulation.One of the fascinating aspects of this line of study is that it unitesconcepts that were “reserved” to control theory (such as controlla-bility and observability) with concepts that “belong” to computerscience and linguistics (such as context-free languages.) He enjoysseeing disciplines interact.

Alexander M. Meystel Professor


Education M.S. E.E., Odessa Polytechnical Institute 1957Ph.D., ENIMS, Moscow 1965

ProfileDr. Meystel’s research interests are in the areas of intelligent con-trol, autonomous robots, learning systems, computer architecturesfor cognitive machines and manufacturing, and the theory ofknowledge representation.

From 1983 to 1987, he developed an outdoor autonomousmobile robot, based on a Dune-Buggy and funded by theU.S. Army. Through 1987-1990, he and his students constructedthe Intelligent Material Processing System for OSPREY machine.This spray-casting machine is an example of the class of objects forwhich the intelligent controllers are especially advantageous sincethe system to be controlled is not completely known. OSPREYmachines perform complicated configurations by spraying hotmetal that solidifies on a substrate moving in a sophisticated wayby a robotic arm. The process variables are being measured bynumerous sensors; nevertheless, the process is still not adequatelyrepresented.

Computer controller has been developed at the Laboratory ofApplied Machine Intelligence and Robotics (LAMIR). Thisinvolves using principles of artificial intelligence combined withcontrol theory techniques, and it provides joint control ofmechanical motion of the robotic arm as well as thermal andhydrodynamic processes of the metal spray. The research team ofLAMIR has developed a system for off-line planning, simulation,and animation of the OSPREY processes and an on-line fuzzy con-troller. The OSPREY process had never before been controlledwithout active involvement of a human operator. This intelligentcontroller can be applied for a variety of other systems withincomplete and/or inadequate knowledge representation.

His current research includes the development of massivelyparallel computer architectures for multiresolutional “multigranu-lar” knowledge processing in Intelligent Control Systems, whichinvolves learning, planning, and control of systems with incom-plete and/or inadequate knowledge representation. He and his stu-dents have developed a Nested Hierarchical Architecture for on-line robot learning control (project “Baby Robot”). A similarnested hierarchical control system is being explored for the project“Smart Plant,” which is partially funded by Fluor Daniel viaIMPACT Center.

ProfileDr. Miu’s research interests are in power distribution systemanalysis, automation, and control. The rapid restructuring of elec-

tric power utilities and the availability of customer choice intro-duces a new planning and operating environment for the nation’spower system infrastructure. From the standpoint of power distri-bution systems, this new environment pushes distributionautomation to the forefront as distribution systems are the firstand most prominent link customers have to the power system.

She addresses four main aspects in her research. First, the identi-fication of data requirements necessary for end-use applications,such as three-phase power flow and service restoration. Second,determination of meter placements in distribution networks. Third,the development of accurate load models to represent the distribu-tion loads, which in turn can be incorporated into load forecastingtechniques. Fourth, with specific interest in service-oriented func-tions, like service restoration, maintenance planning, and reliabilityimprovement, the development of problem formulations and effec-tive solution algorithms to represent accurately the behavior of theelectrical system and to reflect the new operating environmentwhich must consider appropriate costs and avoided costs.

ProfileDr. Zhang was a graduate research assistant and instructor in theDepartment of Electrical and Computer Engineering, StevensInstitute of Technology from 1997 to 2000. Since September of2000, he has been an Assistant Professor at Drexel University. Hisresearch interests lie in the area of signal processing for network-ing, a promising research topic. He has investigated the applica-tion of diversity combining, signal separation, and blind process-ing techniques to the random multiple medium access problem inan effort to increase the throughput/delay performance. Furthertopics include the joint optimization of the physical/data-linelayer, physical/network layer, and physical/transport layer proto-cols. His future research will focus on applying statistical signal,array processing, and adaptive signal processing principles to

achieve improvements in power and bandwidth, admission con-trol, scheduling, and resource allocation.
