Message from Chairman’s Office
Since 1923 the Fenn College of Engineering has provided high quality
undergraduate and graduate engineering programs to students in Northeast Ohio
and beyond. Then in 1964 the College served as the nucleus around which the
State of Ohio established Cleveland State University with its six colleges.
Electrical and Computer Engineering (ECE) is the largest of Fenn College’s six
departments, and it offers two undergraduate degree programs (a BS in
Electrical Engineering and a BS in Computer Engineering), two master’s degree
programs (an MS in Electrical Engineering with an emphasis in either electrical
engineering or computer engineering, and an MS in Software Engineering), and
a Doctoral Degree program.
Besides teaching and conducting research in the more traditional areas of
communications, controls, power electronics, power systems, and digital systems, recent recruitment of faculty in
the areas of computer engineering, software engineering, MEMs, and sensors has greatly expanded ECE’s range
of courses, degrees, and research activities. In addition to its nine research laboratories, the Department’s faculty
play major roles as both leaders and researchers in the college-wide Center for Research in Electronics and
Aerospace Technology (CREATE), as well as in the state-funded multi-university and multi-business $23
million-dollar Wright Center for Sensor Systems Engineering.
Academic programs in the Department of Electrical and Computer Engineering emphasize a blend of practical
experience and academic achievement, and our students often have the opportunity to work on real problems in
industry, in academic research, and at the NASA Glenn Research Center.
ECE’s students come from within and beyond Northeast Ohio, and from many countries, thus collectively
representing a rich mixture of cultures and languages. Graduates of the ECE degree programs are frequently hired
by prominent companies and government agencies such as Rockwell Automation, GE, Motorola, Microsoft,
ABB, Qualcomm, and NASA.
If you have further questions, please contact the Department of Electrical and Computer Engineering at
216-687-2589 to schedule an appointment with our undergraduate or graduate academic advisors, or to talk to us
in general about our activities.

Cleveland State University
Cleveland State University is a state-assisted, comprehensive,
metropolitan university. Cleveland State has about 16,000
students enrolled in 200 major fields of study at the
undergraduate and graduate levels as well as professional
certificate and continuing education programs.
By action of the Ohio General Assembly in 1964, Cleveland
State was created in 1965 to provide quality education at
reasonable cost to the citizens of northeast Ohio. Cleveland
State was created out of the buildings, faculty, staff, and
curriculum of the former Fenn College, a private institution of
2,500 students that was founded in 1923. Later, in 1969, the
Cleveland-Marshall College of Law was merged into
Cleveland State University. Since then, the university has
developed into a comprehensive university with eight colleges:
the College of Liberal Arts and Social Sciences, the College of
Science, the Nance College of Business Administration, the
College of Education and Human Services, the Fenn College of
Engineering, the Maxine Goodman Levin College of Urban
Affairs, the Cleveland-Marshall College of Law, and the
College of Graduate Studies.
Now CSU attracts students from many states in the nation and
many counties of the world.

The Fenn College of Engineering
and the Department of Electrical
and Computer Engineering
Long before the founding of Cleveland State University, the
Fenn College of Engineering had established a reputation for
excellence as early as 1890 when the first engineering course
was offered by the forerunner of Fenn College. The college
consists of six departments: Chemical and Biomedical
Engineering, Civil and Environmental Engineering, Electrical
and Computer Engineering, Industrial and Manufacturing
Engineering, Mechanical Engineering, and Engineering
Technology. The Department of Electrical and Computer
Engineering is the largest of them, both in the numbers of
faculty and students.
The department offers both undergraduate and graduate
degrees, including Bachelor of Electrical Engineering (BEE),
Bachelor of Computer Engineering (BCE), Master of Science
in Electrical Engineering (MSEE, with emphasis in either
electrical engineering or computer engineering), Master of
Science in Software Engineering (MSSE), and Doctor of
Engineering (DE).
Our degree programs emphasize a blend of practical experience
and academic achievement. Our programs are interdisciplinary
and closely related to advances in technology.
Faculty research is often sponsored by farsighted organizations
and industries seeking to explore technology challenges.
Computer network security and privacy, high efficiency
modulation and coding techniques, advanced control
algorithms and techniques, embedded systems, micro electrical
and mechanical systems (MEMS), biomedical sensors and
wireless sensor networks are just a few of the areas recently
investigated. Students often have opportunity to work on real
problems in industry and at the NASA Glenn Research Center,
through funded researches or internships.

Science (CIS). The program is the successor to the Graduate
Certificate Program in Software Engineering and is intended
for both practicing professionals, as well as full-time students
in the areas of software engineering, computer engineering,
electrical engineering, computer science, or information
management. The program introduces students to current and
best practices in the engineering of software systems. A
6
distinguishing feature is its emphasis on the architecture,
design, quality, management, and economic aspects of software
engineering. Students take a project from start to completion,
learning the requirements of specific deliverables and the
development life cycle. Critical management issues, such as
risk assessment, project planning, and market analysis, are also
covered. The program exposes students to new technological
developments in an advancing field and how to apply their
knowledge in the workplace. Graduates meet the demands of
industry and address the needs of information technology
professionals, in general, and software engineers, in particular.
The Electrical and Computer Engineering Department recently
commissioned a new state-of-the-art Software Engineering
instructional laboratory, fully equipped with hardware and

Research and Scholarly Projects
Project Title: Design and Prototyping of High Performance
Control Systems for MEMS Gyroscopes
Sponsor: Ohio ICE
Research Team: Dr. Lili Dong (faculty; PI), David Avanesian
(graduate student), Qing Zheng (doctoral student).
Project Description: MEMS gyroscopes are one of the most
important types of silicon-based angular rate sensors on a
micrometer or millimeter scale with micro-resolution. The
higher performance requirements of the MEMS vibratory-rate
gyroscopes in aerospace and military applications require the
development of advanced control technologies to achieve
performance robustness against modeling uncertainties and
disturbance attenuation. This project produced an advanced
control strategy and theoretical proof of the controller on the
MEMS gyroscope. The simulation results verified the
robustness and effectiveness of the controller.

Project Title: Dynamics and Control of Flywheel Energy
Storage System
Sponsor: Department of Energy
Research Team: Dr. Lili Dong (faculty), Baixi Su-Alexander
(graduate student), Rick Rarick (graduate student), Silu You
(graduate student)
Project Description: A flywheel is an ideal electromechanical
energy storage device for its fast charging and discharging
capabilities, high-energy efficiencies, and relatively long life
span. The key component of the flywheel system is a
high-speed rotor that can transfer energy to and from an energy
source (such as solar array). However, the high speed is rarely
achieved because of potentially damaging rotor vibrations at
critical speeds. The objective of the project is to develop a
novel control strategy for effectively reducing the magnitude of
the vibration of the rotor, increasing the speed of the rotor
steadily, compensating all defects and perturbations that affect
the behavior of the flywheel system, and achieving a high
performance of the flywheel in a robust fashion.

Project Title: Active Disturbance Rejection Control
Sponsors: NASA, various industrial partners, and a venture
capital firm.
Research Team: Zhiqiang Gao (faculty; PI), Anthony Roberts,
Qing Zheng and Gang Tian (graduate students), Dapeng Ye
(Visiting Scholar)
Project Description: The aim of our research in the last 15
years has been to find solutions to real industrial control
problems, not just pure theory. These problems often have a
large amount of unknown dynamics and they are in general
nonlinear and time varying, making them almost insolvable in
the existing model-based framework of modern control theory.
At the 2004 American Control Conference we organized a
forum to discuss the big theory-practice gap. In simpler terms,
our approach is to use a very simple model (say, a double
integrator for 2nd order systems) for the controller design and
treat any discrepancy between this model and the plant
(unknown, nonlinear, and time-varying) as disturbance to be
estimated and rejected. The result is a high performance control
system that is tuned by adjusting only one parameter: the loop
bandwidth. We have tested this algorithm on countless
applications with great success. For more details, see

Project Title: Biogeography-based Optimization of Multiple
Related Complex Systems
Sponsor: National Science Foundation
Research Team: Dan Simon (faculty; PI), Jeffrey Abell
(General Motors; co-PI), Mehmet Ergezer (graduate student),
other students TBD
Project Description: The purpose of this collaboration is to
develop a new population-based algorithm for the optimization
of multiple related complex systems. The complex systems that
we optimize are sets of requirements that are specified for
multiple related product designs. The optimization algorithm
that we develop is biogeography-based optimization (BBO),
which is based on the mathematics of biogeography.
Biogeography is the study of the distribution, migration,
speciation, and extinction of biological species. Biogeography
is nature’s way of distributing species, and is analogous to
general problem solutions. A good solution to some problem is
analogous to a habitable island, and a poor solution represents
an island that is less friendly to life. Good solutions resist
change more than poor solutions, just as habitable islands resist
immigration due to their many species. Good solutions share
features with poor solutions, just as habitable islands share
species with other islands via emigration. This means that poor
solutions accept new features from good solutions. This
addition of new features to poor solutions may raise the quality
of those solutions. This is the essence of BBO.
Project Title: Robotic Swarms
Sponsor: CSU Undergraduate research grant
Research Team: Dan Simon (faculty; PI), Rick Rarick
(graduate student), Maria Baker (undergraduate student), Chris
Churavy (undergraduate student), Samarth Mehta
(undergraduate student), Ishu Pradhan (undergraduate student),
Steven Shanfelt (undergraduate student), Nina Sheidegger
(undergraduate student)

sensors, including ultrasonic sensors for obstacle detection, a
camera, radio transceivers, wall-following sensors, a
gyroscope, wheel encoders, and a LCD display. Each robot
takes a different path through the building, communicating its

the base station.
Project Title: Sinusoid Motor Drive Compensation
Sponsor: Arcus Technology

Project Title: Optimal Robot Trajectory Planning Using
Evolutionary Algorithms
Sponsor: Cleveland State University
Research Team: Dan Simon (faculty; PI), Bhanu Gouda
(graduate student)
Project Description: An optimal trajectory planning approach
using evolutionary methods is developed for an industrial
manipulator. Minimum energy consumption is used as a
criterion for trajectory generation, and is achieved using genetic
algorithms as an optimization tool. Cubic splines are used to

Project Title: Optimal Filtering for Stream Flow Forecasting
Sponsor: Cleveland State University
Research Team: Dan Simon (faculty; PI), Vinay Kantamneni
(graduate student)
Project Description: Streamflow forecasting models are
developed and optimal filtering techniques are applied to
update soil moisture values and to improve streamflow
predictions. Kalman and H-infinity filters are used to update
daily estimates of soil water content. Updated soil moisture
storages are then used to predict daily streamflow. The output
from the estimators is compared with the model output without
state updating, the simulation results from the National
Weather Service, and the observed streamflow. It is seen that
Kalman and H-infinity filtering provide improved streamflow
forecasting compared with existing methods.
Project Title: A Microcomputer-Controlled Calorie Monitor
for Human Powered Vehicles
Sponsor: Cleveland State University
Research Team: Dan Simon (faculty; PI), Gary Siegmund
(graduate student)
Project Description: The amount of calories expended during
an exercise interval is a primary indication of training intensity
and effectiveness. If the exercise apparatus is a human powered
vehicle, the potential exists for effectively measuring several
parameters of the training session. Unfortunately, existing
monitoring systems are either invasive or inaccurate. This work
describes the design of an energy monitoring system that
displays the cumulative calories expended during a riding
interval, without requiring attachments to the body of the
participant, or modification of the vehicle.
Project Title: Fuzzy Logic Control for an Autonomous Mobile
Robot
Sponsor: Cleveland State University
Research Team: Dan Simon (faculty; PI), Vamsi Mohan Peri
(graduate student)
Project Description: An autonomous wall-following robot is
designed. The wall-following controller is a two input, two
output system. The inputs are two proximity measurements to
the wall, and the outputs are the speeds of the two rear wheels.
For the embedded fuzzy logic controller, the behavior must be
approximately encoded for the target processor, and then
downloaded to the chip for execution. The target system is a
small mobile robot equipped with an embedded microcontroller
based on a Microchip microcontroller. The robot is driven by
two independent servo motors. Three ultrasonic range sensors
are used by the robot: two on one side (the controller inputs)
and one in the front (for emergency stop in case of an obstacle).
Since all the control circuitry and computation are embedded in
the robot, it is self contained and travels without the need for
any data link to external processors such as a PC. The detection
of a wall by the sensors activates the controller which attempts
to align the robot with the wall at a specified reference distance.
Once aligned, the robot follows the wall and attempts to
maintain alignment by compensating for lateral drift.
Project Title: Health Parameter Estimation of Turbofan
Aircraft Engine
Sponsor: NASA
Research Team: Dan Simon (faculty; PI), Srikiran Kosanam
(graduate student)
Project Description: Aircraft health monitoring has been a
challenging task for over decades. In turbofan jet engines the
parameters which describe the health of the engine cannot be
measured explicitly. One possible solution to this problem is
Kalman filter. The traditional Kalman filter is optimal as long
as the modeling of the plant is accurate. We show a way of
linearizing the jet engine model so that theoretically proven
estimation techniques can be applied to this problem. We
present the application of Kalman filter to health parameter
monitoring of the gas turbine engine. It is shown that the
standard Kalman filter will not be robust enough if there are
uncertainties in the modeling of the plant. A new filter is
developed which addresses the uncertainties in the process
noise and measurement noise covariances. A hybrid gradient
descent algorithm is used to tune the new filter gain. This filter
is then implemented for the health parameter estimation. The
results show significant decrease in the estimation error
covariance. It is shown that advanced search algorithms like
genetic algorithms prove to be superior to hybrid gradient
descent in searching for better minima.

Project Title: Analysis and Implementation of a Dimmable
Low Frequency Electronic HID Ballast
Sponsor: General Electric Lighting
Research Team: Ana V. Stankovic (faculty; PI), Prerana
Kulkarni (graduate student)
Project Description: This project focuses on the analysis,
design and implementation of dimmable low frequency
electronic High-Intensity-Discharge (HID) ballast, using the
variable dc link voltage with constant switching frequency
technique. Where previously this dimming technique was used
for high frequency ballasts, in this application, the technique is
applied to low frequency square wave electronic HID ballast, to
dim high pressure sodium (HPS) lamp. Low frequency
operation ensures an acoustic resonance free operation, low
switching losses, better efficiency and thus low cost.

obstacles to realizing this potential, however: the methods and
tools available for constructing sensornet software are too
brittle, and require specialized training to use effectively. This
CAREER project is investigating ways to overcome these
obstacles. In particular, this project involves creating
programming and middleware artifacts, specification and
reasoning techniques, and toolsets that can be easily used by

frequency synchronization algorithms have been proposed by
Shi & Serpedin and Morelli & Mengali used for general OFDM
system that is based on IFFT/FFT pair. We modified these two
algorithms to suit to our system. Especially, we improved the
first algorithm to extend the frequency acquisition range. These
two schemes are based on the transmission of a training symbol

Project Title: Stabilization of Immobilized Enzymes for
Implantable Glucose Monitoring Devices
Sponsor: American Diabetes Association
Research Team: Siu-Tung Yau (faculty, PI), Research
assistant (TBD)
Project Description: In the USA, 20.8 million people have
diabetes. More than 200 000 Americans die from this chronic
disease annually. Effective treatment of diabetes requires
accurate monitoring of glucose in the patient’s blood. The
approach of continuous-glucose-monitoring could provide
diabetics with a complete glucose profile with instantaneous
fluctuations throughout the day, allowing optimized insulin
therapy and metabolic control, which drastically reduce the risk
of chronic complications. To implement this approach, the
glucose sensor needs to be implanted in the patient’s body to
facilitate periodic and frequent glucose measurement. One of
the main obstacles for the development of implantable glucose
biosensors is the inherent instability of the enzyme
immobilized on the electrodes of the sensors as the sensing
element. When immobilized on an electrode and subjected to
in-vivo conditions, enzymes will become unstable and will lose
their sensing ability, making long-term implant tasks
unrealistic. This project is proposed to overcome this crucial
obstacle using a spatial confinement approach. Enzymes will be
assembled into spatially confining fabricated on electrodes,
which will increase the stability of the enzymes and enable
them to perform sensing tasks under long-term in-vivo
conditions. Prototype glucose biosensors and glucose biofuel
cells, which could be used as the power supply for implanted
sensors, will be constructed and tested under long-term in-vitro
condition. The successful completion of the project will be a
substantial advance toward making implantable
glucose-sensing devices, which can be further developed for
the artificial pancreas.

techniques are used to preserve the activities of the enzymes.
The enzyme-immobilized silicon wafer is used as the sensing
electrode in the construction of biosensors used to detect
chemical substances that are important in biomedicine, human
health, food processing, environment protection and national
security. A particularly emphasized study is the construction of
biosensors for implantable applications. Here, glucose oxidase,
the enzyme that is used as the sensing element in commercial
glucose sensors, is immobilized on silicon wafers, whose
performance as sensing electrode is tested under long-term in
vivo conditions.
Project Title: Nanoparticle-Based (Enzymeless) Sensors
Sponsor: Cleveland State University
Research Team: Siu-Tung Yau (faculty, PI), Yongki Choi
(graduate student)
Project Description: The newly-discovered colloidal silicon
nanoparticles are used as the sensing element for non-enzyme
sensors. With this kind of sensor, we have demonstrated direct
electrochemical amperometric detection of different forms of
sugar (glucose, fructose and lactose), dopamine, hydrogen
peroxide and phenol. In the sensing of glucose, the sensor
showed exclusive detection of glucose in the presence of
interfering species within the physiological concentration
ranges of these substances. The sensor also showed negligible
electrode poisoning and detection stability over a 14-week
period of repeated use. A comparison between the glucose
detection characteristics of the nanoparticle-based sensor and
those of the enzyme-based sensor shows an enhanced
amperometric response of the particle sensor. Our results reveal
several advantages of using the silicon nanoparticle in
bioelectronics. This particle-based sensor is being developed
for applications in food processing, biomedicine and
environmental monitoring.
Project Title: Biofuel Cells

Project Description: In this project, the two criteria that
determine the performance of a biofuel cell, namely, high
output current and enzyme stability are addressed. High current
density is obtained with enhanced electron transfer at the
enzyme-electrode interface using different immobilization
techniques, which also enhance the stability of enzymes. We
have constructed double-compartment biofuel cell operating on
ethanol and single-compartment (membrane-less) biofuel cell
operating on glucose. The objective of this project is to realize
miniature biofuel cells that can be used as implantable power
supplies.

Research Team: Siu-Tung Yau (faculty, PI), Yongki Choi
(graduate student)
Project Description: Here, we prepare novel bulk electronic
materials using nanoscale objects as active centers. Recently,
we have prepared a two-phase composite material by mixing
the polymer Nafion with an electroactive molecule, potassium
ferricyanide. The current-voltage characteristic of the material
22
shows a metal-like electrical conduction about zero-bias. The
conductance is found to be proportional to the concentration of
the potassium ferricyanide molecule and temperature. A
conductance peak is present at a low bias voltage, providing a
region of negative differential resistance. Other nanoscale
objects such as semiconductor quantum dots and proteins are
also used as active substances in our studies.

Project Description: Mobile networks are vulnerable to the
presence of extreme conditions such as network partitions (due
to high node speeds) and strong interference (in urban
environments). As existing link and network layer solutions do
not take these extreme conditions into consideration, it is

dependable subnet under such situations. The goal of this
project is to investigate the performance of mobile wireless
networks in highly stressed environment and to seek novel
methods to survive the stress and achieve a reasonable
performance.

Project Title: Byzantine Fault Tolerance for Long Running,
Non-deterministic Applications (from 9/1/2008)
Sponsor: National Science Foundation, Major Research
Instrumentation Grant
Research Team: Wenbing Zhao, Honglei Zhang, Hua Chai
Project Description: In this project, we aim to develop
efficient techniques to ensure strong replica consistency and the
long-term dependability of Web-based mission-critical systems,
including Web services and online database systems. In
particular, we focus on three sub-projects: (1) We propose
novel methods to reconcile the seemingly conflicting
requirements of strong replica consistency and the
independence of each individual replica in a Byzantine
fault-tolerant (BFT) system. For many applications, including
security services, it is ultimately important for each replica to
make decisions based on its own, possibly randomized, input.
The method proposed in this project will be urgently needed for
these types of applications to maintain strong replica
consistency while preserving their robustness. (2) We will
investigate the possibility of using software transactional
memory (STM) as a way to ease the programming complexity
and to increase the degree of concurrency obtainable for large
scale replicated distributed systems. (3) We propose a new
migration-based proactive recovery scheme that achieves a
very small vulnerability window, and hence, helps achieve
long-term dependability of mission critical systems. To assess
the practicality of our techniques, and to gain better insight on
the problems, we plan to build a prototype of a BFT
infrastructure and to perform empirical experimental study in
both local and wide area network environments.

Sponsor: Cleveland State University, Faculty Research
Development Award
Research Team: Wenbing Zhao, Honglei Zhang, Hua Chai,
Bo Chen, and Srikanth Dropati
Project Description: The Web services platform has been
adopted by virtually all businesses and government
organizations as the distributed computing platform of choice
23
due to its strong interoperability, loose-coupling, and
extensibility design. In this project, we focus on developing
fault and intrusion tolerance frameworks that have the
following characteristics: (1) the design of the dependability
mechanisms are conformant to the design principles of Web
services; (2) the mechanisms are backward compatible with
WS-standards; (3) the frameworks incur minimum overhead
and require minimum changes to the application programs. The
frameworks support both generic Web services and specific
Web services applications such as transactional applications
and wireless Web services applications.
Project Title: A Reservation-Based Extended Transaction
Protocol (completed)
Sponsor: Cleveland State University, Faculty Startup Award
Research Team: Wenbing Zhao (in collaboration with Dr.
Louise Moser and Dr. P. Michael Melliar-Smith at UCSB)
Project Description: Existing extended transaction protocols
typically rely on compensating transactions to handle
exceptional conditions. In this project, we identified a number
of issues with compensation-based extended transaction
protocols, and proposed a reservation-based extended
transaction protocol that addresses those issues. Moreover, we
introduced a set of properties, analogous to the ACID
properties of traditional transactions that are more appropriate
for business activities that span multiple enterprises. In addition,
we compared our reservation protocol with other extended
transaction protocols for coordinating business activities, and
carried performance analyses.

these systems in 802.11 networks to see which strategy works
best in this new environment.
