When an atomic/molecular system controlled by an external field (to imprint information on it, such as preparing a qubit), is brought near a plasmonic nanostructure, the control problem changes. On one hand, the field experienced by the atom is modified due to the plasmon effect…
There has been a wide spread research in the field of sports biomechanics, providing useful information about the risk of injuries in various sports. This information is beneficial in educating athletes and professional trainers about the possible risk of injuries and providing …
This research investigates the performance of Castillo-Grone's Mimetic (CGM) difference operators in 2D and 3D fully curvilinear grids. A software package is provided that assists the user in generating Laplacian operator in fully curvilinear grids using higher order CGM operato…
Knowledge-Based Decision Support System (K-BDSS) are a group of tools capable of displaying variations and their relevant details, a variety of filtered knowledge, integrating traditional DSS with the advances of expert systems and various analyses of the available knowledge. Th…
Depending on the role of software in everyday life, the cost of a software failure can sometimes be unaffordable. During system execution, errors may occur in system components and failures may be manifested due to these errors. These errors differ with respect to their effects …
Efficient and reliable techniques for power delivery and utilization are needed to account for the increased penetration of renewable energy sources in electric power systems. Such methods are also required for current and future demands of plug-in electric vehicles and high-pow…
We developed a novel large-stroke deformable mirror for focus control and spherical aberration correction. The mirrors fabricated using MEMS technology provide full range (150-200 μm in tissue) of focus scanning at high numerical aperture (N.A.=0.5-0.7) for confocal microscopy a…
This dissertation proposes new optimization algorithms targeting protein-protein docking which is an important class of problems in computational structural biology. The ultimate goal of docking methods is to predict the 3-dimensional structure of a stable protein-protein comple…
Electrocardiogram (ECG) is an important biomedical tool for the diagnosis of heart disorders. Recent studies have worked a lot on designing automatic diagnosis systems to help physicians. However, automatic study of ECG patterns and heart rate variability is difficult due to the…
To secure today's computer systems, it is critical to have different intrusion detection sensors embedded in them. The complexity of distributed computer systems makes it difficult to determine the appropriate choice and placement of these detectors because there are many possib…
Scope and Method of Study. Described is an uncooled surface-micromachined thermoelectric (TE) infrared detector that features P-doped polysilicon/Nichrome (Cr20-Ni80) as the thermocouple material pair embedded in Parylene-N, which isolates the hot junction from the substrate. Si…
It has been known for a long time that as neurons within the brain fire, some measurable electrical activities is produced. Electroencephalography (EEG) is one way of measuring and recording of the electrical signals produced by these electrical activities via some sensor arrays…
The design and development of embedded hard real-time (RT) systems is one of the most complex software development practices, because of the criticality and timeliness required for these systems. One critical aspect of RT systems is the production of outputs before the specified…
Security in travel is primary concern for everyone. This project presents an automotive localization system using GPS and GSM-SMS services. When the vehicle is involved in an accident immediately an SMS will send to predefined numbers with GPS location by using vibration sensor.…
Software refactoring is the process of changing a software system in a manner that does not alter its external behavior and yet improving its internal structure. Model-Driven Architecture and the popularity of the UML have enabled the application of refactoring at model-level wh…
In this work we present numerical methods that are suitable for studying a variety of electrochemical systems, such as charging kinetics of porous electrodes used in energy storage devices (e.g. supercapacitors, batteries, or fuel cells), calculation of binding energies in biomo…
Reduced scaling of feature sizes and process variations in CMOS nano-technologies introduce manufacturing anomalies that reduce yield, and this trend is predicted to get worse for emerging technologies. In addition, it takes more time to be resolved these issues compared to prev…
The earthquake of Northridge, CA in 1994 caused damages in steel moment frame buildings due to the brittle fractures in beam to column connections. This led to the modifications and improvements in the connection detailing used prior to the Northbridge earthquake. These improvem…
