Wireless digital data system designers have formidable future design challenges in order to provide the mobile user with a quality of service comparable to that of a wireline system in such metrics as responsiveness, quality, and throughput. The goal of…

One way to reduce the complexity of the speech recognition is to use syntactic, semantic and pragmatic information to predict the next input of the user. In spoken dialogue systems pragmatic information can include knowledge about the dialogue domain, dialogue…

In the context of teleoperated mobile robotics, the use of video data is one of the most desirable sensing modalities for vehicle guidance. Unfortunately, maintaining reliable noise-free video transmission, especially in cost sensitive teleoperation applications is a frequent problem., We…

We present a novel approach to simulate the motion of vortex filaments in three dimensional, incompressible flows. We represent vortex filaments as thin tubes on a 3D-grid and use a Lagrangian vortex filament method to describe their motion within a…

This thesis considers an object-oriented approach to dimensional analysis for engineering design. A dimensional analysis system is developed which can be applied to the knowledge-based engineering design especially of electromagnetic devices. All the system is coded in C++. A shell…

Simulation is the technique by which a physical system can be represented mathematically by a computer program for the solution of a problem. This technique of problem solving is used when it is not feasible due to time, cost, or…

To facilitate proper recognition of a human's action from a video sequence, several key features must first be determined. Initially, the person performing the action must be isolated from the background scene. This information is then used to decipher pertinent…

The discipline of automated theorem proving encompasses techniques which allow us to find a justification of a logical statement expressing an assertion in some domain of knowledge. Beside obvious importance for mathematics, many of the tasks traditionally associated with human…

We study the problem of classifying stop and nasal consonants in continuous speech independently of the speaker. We consider some acoustic parameters computed from the auditory spectrogram, and other parameters computed from the speech waveform. The classification algorithm uses a…

A computer vision system which tracks and analyses living cells and their offspring from sequential two-dimensional images is described. The cells are segmented using a method which combines global thresholding, component labeling and noise filtering. The shapes of the cells…
