Swarm behavior indicates the direct or indirect interactions among relatively simple agents to perform a particular task that is unknown to the individual agent. The study of swarm behavior originates from the research of swarms in...
In this research, two important concepts concerning parallel robots are investigated: compliance and fault tolerance. First, we address the issue of synthesizing a suitable compliance. This is an important problem since a well-designed...
The demand for high-speed mobile wireless communications is rapidly growing. MIMO technology promises to be a key technique for achieving the high date capacity and spectral efficiency for wireless communication systems of the near...
Many phenomena in ecology, evolution, and organismal biology relate to how a system changes through time. Unfortunately, most of the statistical methods that are common in these fields represent samples as static scalars or vectors....
Image segmentation is one of the most important categories of image processing. The purpose of image segmentation is to divide an original image into homogeneous regions. It can be applied as a pre-processing stage for other image...
Filtering is an important aspect of the modern power system. By reducing the effects of harmonics, power transmission and utilization becomes more efficient. This research examines the use of neural networks for the estimation and...
The prediction of any aspect of the future has always fascinated mankind because of the possible benefits of this knowledge, especially financial benefits. From year to year, many stockholders would like to be able to know if the price...
Two leading theories exist to explain the progenitor models of Type Ia supernovae. In the single-degenerate scenario (SDS), a carbon-oxygen white dwarf slowly accretes matter from a non-degenerate binary companion that is exceeding its...
We study the evolution of the collapsing core of a 15 solar mass blue supergiant supernova progenitor from the moment shortly after core bounce until 1.5 seconds later. We present a sample of two- and three-dimensional hydrodynamic...
Noctiluca Miliaris is a single cell, multi-membrane organism that has bioluminescent capabilities. This luminescent ability is closely associated with the flash triggering potential produced by an excitable membrane under active...
Next generation sequencing can rapidly analyze entire genomes in just hours. However, due to the nature of the sequencing process, errors may arise which limit the accuracy of the reads obtained. Luckily, modern sequencing technologies...
We outline a new approach to objectively locate and define mesoscale oceanic features from satellite derived ocean color data. Modern edge detection algorithms are robust and accurate for most applications, oceanic satellite observations...
Mines pose a major threat to the fleet. Finding and clearing minefields is an extremely important but difficult task. In response, systems have been produced to scan the sea floor for mines. A tow fish, used in mine countermeasures by...
Waveform distortions in power systems are inherently time-varying due to continuous changes in system configurations, load types, and load levels. The time-varying nature of waveform distortions requires a real time tool to process that...
Prediction markets have been demonstrated to be accurate predictors of the outcomes of future events. They have been successfully used to predict the outcomes of sporting events, political elections and even business decisions. Their...
Wavelets are mathematical functions that cut up data into different frequency components, and then study each component with a resolution matched to its scale. Wavelets are an extremely useful tool for coding images and other real...
This thesis explores possible improvements in the construction of Delaunay Triangulations on the Sphere by designing and implementing a parallel alternative to the software package STRIPACK. First, it gives an introduction to Delaunay...
In this master's thesis a performance analysis of Optical CDMA systems is conducted. This is accomplished by simulating and analyzing various CDMA code sequences. These are modified and implemented for all optical networks, in OCDMA...
To increase autonomous ground vehicle (AGV) safety and efficiency on outdoor terrains the control system should have settings for individual terrains. A first step in such a terrain-dependent control system is classification of the...
Nios Embedded processors provide a powerful, robust platform for developing and implementing complex algorithms. The unique custom instruction feature of Nios processors could be used to enhance the performance of these algorithms...
The development of robust thermal barrier coating (TBC) systems is crucial in many high-temperature applications. The performance of a TBC system is significantly limited by microstructural evolution mechanisms, such as sintering at...
The advent of geometric morphometrics and the revitalization of artificial neural networks have created powerful new tools to classify morphological structures to groups. Although these two approaches have already been combined, there...
This dissertation addresses the synthesis of antenna arrays using the Cross-Entropy (CE) method, marking the first application of the CE method for solving electromagnetic optimization problems. The CE method is a general stochastic...
In experimental and computational science and engineering, there are a host of practical problems where some tell-tale signs appear well before a critical event of interest surfaces, e.g., the occurrence of tumor is preceded by gradual...
This work implements inverse methods in various polymer characterization problems. In the first topic, a new approach is proposed to infer the comonomer content using Crystaf method considering and quantifying the associated uncertainty....
Different sources of uncertainties have been inevitably induced into the environmental modeling due to different reasons such as the variability in the future climate state, incomplete knowledge and complexity of the nature system, and...
Energy harvesting and alternative renewable energy techniques are currently some of the most sought after research topics for engineers and scientists. Global warming has forced the researchers to abandon the rampant use of coal...
Recently the Wavelet Transform has gained a lot of popularity in the field of signal processing. This is due to its capability of providing both time and frequency information simultaneously, hence giving a time-frequency representation...
