This thesis presents a modular, general-purpose interconnection network simulator called NETSIM developed as an extension to YACSIM, a C-language based process-oriented discrete event simulator. NETSIM is capable of simulating a wide range of switch architectures and network topologies. A NETSIM model can be simulated in a stand-alone mode with the ...

Representation of an abstract system by a mathematical object such as a matrix or a differential equation is important because much of the analysis is done via representations. For discrete-time input-output systems, infinite-matrix kernel representation is the most general representation. We use the notion of finite-horizon systems to characterize ...

Linear multiuser detectors have been developed for CDMA systems to maintain a balance between the performance and computational complexity of the detectors. However for a system with a large number of users and huge data block length, the cubic complexity of these naive algorithms is computationally prohibitive for real time estimation of transmitted ...

Process design for integrated circuit manufacturing has traditionally been implemented with little simulation prior to fabrication. As with circuit design of a decade ago, the available simulation tools were mainframe-based, often incompatible, and lacked accurate physical models. Recent developments in process and device simulation allow accurate ...

In this thesis, a methodology and techniques for the design of a laser range imaging device (LRID) for robotic applications are presented. Furthermore, a prototype incorporating the concepts presented has been successfully tested in the laboratory. In this LRID, the range is determined by the shift in phase in the return of a modulated laser beam ...

This dissertation develops several new results on wavelet design using both traditional and new optimization criteria. We consider three different design problems: two problems address explicit optimization of function properties, and the third problem addresses optimization of filter properties. The first design is a generalization of the maximally ...

Digital transmission over copper loops is studied. Models are found of main sources of interference, including near-end crosstalk (NEXT), far-end crosstalk (FEXT), impulse noise (IN) and intersymbol interference (ISI). Importance Sampling theory is introduced, and an explanation is given of how it can be used to efficiently estimate the bit error ...

Because of the electrical insulating properties of polyimide, it is widely used in the packaging of semiconductor chips. However, it has been documented that the electrical resistivity can be decreased by several orders of magnitude to about 0.1--1 O-cm when irradiated with ultraviolet laser light. This unique property of polyimide can be exploited ...

As robotics has begun to spread from the accessible arenas of laboratories and industry into more dangerous and remote environments such as space or hazardous waste remediation tanks, the need for autonomous and intelligent robotic fault detection and fault tolerance has increased. Our original fault detection and tolerance algorithms enabled the ...

The metal-insulator transition observed in krypton-fluoride laser irradiated polyimide is used as a method to study the three dimensional percolation theory of random resistor networks. Values for the percolation threshold and conductivity critical exponent were measured and found to be 0.31 $\pm$ 0.06 for the percolation threshold of a three dimensional ...
