Pipelined analog to digital converters (ADCs) are very important building
blocks in many electronic systems such as high quality video systems, high
performance digital communication systems and high speed data acquisi ...
A new method is presented to compress switching information in large digital
circuits. This is combined with an efficient approach of generating the noise
signatures of cells in a digital library that results in an acc ...
A tuning technique which tunes the continuous time filter very accurately is proposed in this thesis. This technique overcomes the problem of master slave mismatch, thus tuning the filter accurately. The mismatch minimiz ...
The main achievement of this thesis is the development of a two-sheet charge simulation
model with space charge creation by trap-to-band impact ionization to describe the
electrical characteristics of alternating-curre ...
Semi-supervised clustering aims to improve clustering performance by considering user supervision in the form of pairwise constraints. In this paper, we study the active learning problem of selecting pairwise must-link a ...
We developed and investigated machine learning methods that require
minimal preprocessing of the input data, use few training examples, run fast, and
still obtain high levels of accuracy.
Most approaches to designing ...
An active-matrix electroluminescent (AMEL) design tool has been developed for
the simulation of AMEL display devices. The AMEL design tool is a software package
that simulates AMEL device operation using a lumped param ...
An active object system is a transition-based object-oriented system suitable
for the design of various concurrent systems. An AOS consists of a collection
of interacting objects, where the behavior of each object is d ...
With the increased attention on high efficiency and energy savings, power electronic
energy conversion equipment is increasingly incorporated in all levels of the power system.
The drawback of such equipment is the gen ...
Long bridges tend to develop large deformations under the
action of intense dynamical loads such as wind or earthquakes.
Unless these deformations are controlled in some fashion, the
structure might suffer damage or e ...
Knowledge workers are struggling in the information flood. There is a growing interest in intelligent desktop environments that help knowledge workers organize their daily life. Intelligent desktop environments allow the ...
Partial programming is a field of study where users specify an outline or skeleton of a program,
but leave various parts undefined. The undefined parts are then completed by an external
mechanism to form a complete pro ...
Increasing densities on magnetic data storage devices leads to problems of
severe intersymbol interference (ISI), additive noise and non-linearities. Advanced
detection strategies for magnetic recording channels fall i ...
Oversampling analog-to-digital and digital-to-analog converters are gaining more
popularity in many signal processing applications. Delta-sigma modulators are used in practical applications of oversampling systems becau ...
This thesis presents an adaptive modulation scheme using a Walsh-code
modulator. The Walsh-code modulator consists of a dynamic demultiplexer and
predetermined sets of orthogonal Walsh-Hadamard codes. The demultiplexer ...
The thesis presents a new algorithm and structure that is to be used in conjunction
with a specially modified CMOS Gilbert cell mixer to remove time-varying DC offsets
in direct conversion receivers. In our approach, t ...
As the number of mobile devices accessing large-scale WLANs such as campus
and metropolitan area networks increases, the need for load balancing among the
cells becomes crucial. In addition, the network must also suppo ...

This thesis presents an adaptive model reference controller for a highly
maneuverable high performance aircraft, in particular, a modified F18. An adaptive
controller is developed to maneuver an aircraft at a high angl ...
A general discrete-time, adaptive, multidimensional framework is introduced
for estimating the motion of one or several object features from their successive
non-linear projections on an image plane. The motion model c ...
