MULTIPLEXED PHOTOMETRY AND FLUORIMETRY USING MULTIPLE FREQUENCY CHANNELS

by

Advisor: Dr. Amar Basu

Major: Electrical Engineering

Degree: Doctor of Philosophy

Multispectral photometry and fluorimetry are useful for quantifying and distinguishing samples during flow injection analysis, flow cytometry, and ratiometric absorbance measurement. However, multispectral detectors, including spectrometers, typically require arrayed or multiple light detectors, optical components, and path alignments, all of which increases the size and cost of the detection system. Several previous efforts have attempted the use of time division multiplexing or frequency division multiplexing (FDM) techniques to minimize both size …

Emerging Design Methodology And Its Implementation Through Rns And Qca, Omar Dajani

Wayne State University Dissertations

Digital logic technology has been changing dramatically from integrated circuits, to a Very Large Scale Integrated circuits (VLSI) and to a nanotechnology logic circuits. Research focused on increasing the speed and reducing the size of the circuit design. Residue Number System (RNS) architecture has ability to support high speed concurrent arithmetic applications. To reduce the size, Quantum-Dot Cellular Automata (QCA) has become one of the new nanotechnology research field and has received a lot of attention within the engineering community due to its small size and ultralow power.

In the last decade, residue number system has received increased attention due …

Supervisory Controller Validation For A Plug-In Parallel-Through-The-Road Hybrid Electric Vehicle By Software-In-The-Loop Testing, Love Lor

Wayne State University Theses

The goal of this research is to develop an operational supervisory controller for Wayne State University Hybrid Warriors' hybrid electric vehicle architecture that can be transitioned easily to a hardware-in-the-loop testing environment for the 2011-2014 EcoCAR2 competition. It serves to demonstrate how model-based design, specifically software-in-the-loop testing, is effective for the initial steps in design, verification, and validation of a supervisory control strategy. Overall, the supervisory controller aims to meet all safety and functional requirements while reducing fuel consumption. The thesis starts by presenting a plug-in parallel-through-the-road architecture and its powertrain hardware components. Next, characteristics and capabilities of all significant …

ABSTRACT

MODELING OF MOUSE EYE AND ERRORS IN OCULAR PARAMETERS AFFECTING REFRACTIVE STATE

by

GURINDER BAWA

September 2013

Advisor: Dr. Ivan Avrutsky

Major: Electrical Engineering

Degree: Doctor of Philosophy

Rodents eye are particularly used to study refractive error state of an eye and development of refractive eye. Genetic organization of rodents is similar to that of humans, which makes them interesting candidates to be researched upon. From rodents family mice models are encouraged over rats because of availability of genetically engineered models. Despite of extensive work that has been performed on mice and rat models, still no one is able …

Real Time Estimation, Quantization, And Remote Control Of Permanent Magnet Dc Motors, Mohammad Obeidat

Wayne State University Dissertations

Establishing real-time models for electric motors is of importance for capturing authentic dynamic behavior of the motors to improve control performance, enhance robustness, and support diagnosis. Quantized sensors are less expensive and remote controlled motors mandate signal quantization. Such limitations on observations introduce challenging issues in motor parameter estimation. This dissertation develops estimators for model parameters of permanent magnet direct current motors (PMDC) using quantized speed measurements. A typical linearized model structure of PMDC motors is used as a benchmark platform to demonstrate the technology, its key properties, and benefits. Convergence properties are established. Simulations and experimental studies are performed …

Opacity Of Discrete Event Systems: Analysis And Control, Majed Mohamed Ben Kalefa

Wayne State University Dissertations

The exchange of sensitive information in many systems over a network can be manipulated

by unauthorized access. Opacity is a property to investigate security and

privacy problems in such systems. Opacity characterizes whether a secret information

of a system can be inferred by an unauthorized user. One approach to verify security

and privacy properties using opacity problem is to model the system that may leak confidential

information as a discrete event system. The problem that has not investigated

intensively is the enforcement of opacity properties by supervisory control. In other

words, constructing a minimally restrictive supervisor to limit the system's …
