Enhancements in Markovian Dynamics
… On the first half of this dissertation we study enhancements on the theory of hidden Markov modeling. These include three branches: 1) a robust as well as a closed-form parameter estimation solution to the expectation maximization (EM) process of HMMs for the case of elliptically symmetrical …

Enhancements to Hierarchical Pathfinding Algorithms
… Planning Competition, and implemented several enhancements to experiment with the tradeoff between memory usage and search speed. Our program returns the refined low-level path incrementally, therefore reduces the first-move lag in large maps. We cache the low-level edge paths during runtime to …

Starlogo camera controls and enhancements
The purpose of this research and development project was to further develop Starlogo, a block based programming environment to allow students to create 3D games and simulations to help them learn programming. I improved the Sarlogo "camera", a representation of the view within a 3D world. Starlogo …

Algorithmic enhancements to polynomial matrix factorisations
In broadband array processing applications, an extension of the eigenvalue decomposition (EVD) to parahermitian Laurent polynomial matrices - named the polynomial matrix EVD (PEVD) - has proven to be a useful tool for the decomposition of spacetime covariance matrices and their associated …

Reconstruction Enhancements with Optical Scanning Holography
Optical scanning holography (OSH) [1] has the benefit of recording the entire three-dimensional (3-D) volume of a specimen in the form of a two-dimensional (2-D) hologram. Reconstruction of the original volume can be accomplished by applying digital reconstruction or decoding techniques to the …

Assessing the Moral Evaluations of Pharmacological Enhancements
… on the ways in which the use of pharmacological enhancements should affect our moral evaluations. I’m concerned with this central question: how should our decision to enhance or not affect our evaluation of the act or person in question? I discuss a number of moral evaluations including deontic …

DIMTEST Enhancements and Some Parametric IRT Asymptotics
The joint consistency of item and ability parameter estimation remains a challenging problem in IRT parametric modeling. Although many simulation studies have been conducted on the item and ability parameter estimates obtained by joint maximum likelihood estimation which is implemented in LOGIST …

Performance enhancements for a dynamic invariant detector
Dynamic invariant detection is the identification of the likely properties about a program based on observed variable values during program execution. While other dynamic invariant detectors use a brute force algorithm, Daikon adds powerful optimizations to provide more scalable invariant detection …

Enhancements to Transportation Analysis and Simulation Systems
Urban travel demand forecasting and traffic assignment models are important tools in developing transportation plans for a metropolitan area. These tools provide forecasts of urban travel patterns under various transportation supply conditions. The predicted travel patterns then provide useful …

Network Theoretic Analyses and Enhancements of Evolutionary Algorithms
<p>Information in evolutionary algorithms is available at multiple levels; however most analyses focus on the individual level. This dissertation extracts useful information from networks and communities formed by examining interrelationships between individuals in the populations as they change …

Physical Testing of Potential Football Helmet Design Enhancements
<p>Football is a much loved sport in the United States. Unfortunately, it is also hard on the players and puts them at very high risk of concussion. To combat this an inventor in Santa Barbara brought a new design to Cal Poly to be tested.</p> <p>The design was tested in small scale first in order …

The resolution enhancements of real-time captured images
The resolution enhancement of real-time captured images is a problem that this thesis addresses in three ways. First, an improved color filter array interpolation algorithm is proposed, which offers high accuracy with reasonable performance. Second, the thesis discusses a mechanism in which …

A simulation study of reordering-resilient TCP enhancements
TCP traffic makes up a large portion of the Internet's load. The throughput TCP connections are able to obtain depends heavily on the underlying network providing in-order packet delivery. IP networks do not guarantee in-order delivery, but the design of hardware, networks, protocols have been …

Scale-up and Measurement Enhancements of a BioGenerator Bioreactor
Renewable energies in the form of wind and solar have seen steadfast growth across the world, however the abundance of these technologies that demonstrate short-term variability in power output threatens power grid stability and necessitates the use of fossil fuels for rapid throttling capability. …

Fast VMZ : code enhancements for video mosaicing and summarization
Video Mosaicing and Summarization (VMZ) is a novel image processing pipeline that summarizes the content of a long sequence of geospatial or biomedical videos using a few coverage maps or mini mosaics. The existing VMZ algorithm uses Normalized Cross-Correlation (NCC), Structure Tensor (ST), …

Optimization of enhancements to aluminum-based structural energetic materials
Warhead casings are most often made of steel due to its low cost, high strength, good manufacturability, and ability to produce dense high-speed fragments. However, inert steel does not improve blast wave characteristics. In fact, it significantly reduces peak blast pressure and impulse as energy …
