Applying Hessian Curves In Parallel To Improve Elliptic Curve Scalar Multiplication Hardware, F. B. Muhaya, Q. A. Al-Haijá, Lo'ai A. Tawalbeh Jan 2010

Applying Hessian Curves In Parallel To Improve Elliptic Curve Scalar Multiplication Hardware, F. B. Muhaya, Q. A. Al-Haijá, Lo'ai A. Tawalbeh

Computer Science Faculty Publications (Archived)

As a public key cryptography, Elliptic Curve Cryptography (ECC) is well known to be the most secure algorithms that can be used to protect information during the transmission. ECC in its arithmetic computations suffers from modular inversion operation. Modular Inversion is a main arithmetic and very long-time operation that performed by the ECC crypto-processor. The use of projective coordinates to define the Elliptic Curves (EC) instead of affine coordinates replaced the inversion operations by several multiplication operations. Many types of projective coordinates have been proposed for the elliptic curve E: y2 = x3 + ax + b which is defined …

An Intelligent Data-Centric Approach Toward Identification Of Conserved Motifs In Protein Sequences, Kathryn Dempsey Cooper, Benjamin Currall, Richard Hallworth, Hesham Ali Jan 2010

An Intelligent Data-Centric Approach Toward Identification Of Conserved Motifs In Protein Sequences, Kathryn Dempsey Cooper, Benjamin Currall, Richard Hallworth, Hesham Ali

Interdisciplinary Informatics Faculty Proceedings & Presentations

The continued integration of the computational and biological sciences has revolutionized genomic and proteomic studies. However, efficient collaboration between these fields requires the creation of shared standards. A common problem arises when biological input does not properly fit the expectations of the algorithm, which can result in misinterpretation of the output. This potential confounding of input/output is a drawback especially when regarding motif finding software. Here we propose a method for improving output by selecting input based upon evolutionary distance, domain architecture, and known function. This method improved detection of both known and unknown motifs in two separate case studies. …

The Role Of An Effective It Intervention For Microenterprises, Changsoo Song, Sajda Qureshi Jan 2010

The Role Of An Effective It Intervention For Microenterprises, Changsoo Song, Sajda Qureshi

Information Systems and Quantitative Analysis Faculty Proceedings & Presentations

Information technology (IT) interventions for micro-enterprises are fragmented and their approach lacks theoretical foundations. While various researchers have conducted studies on the effects of IT adoption in micro-enterprises, little research has been conducted to explain critical aspects of an effective IT intervention for micro-enterprises from a theoretical perspective. This study aims to fill this gap and empirically investigate how IT interventions can effectively facilitate the process of IT adoption by micro-enterprises. This paper suggests that effective IT interventions may have considerable potential for facilitating IT adoption among micro-enterprises across the United States and the world. Following an analysis of four …

Information Technology Adoption In Latin American Microenterprises, Travis Good, Mehruz Kamal, Sajda Qureshi, Nancy Jimenez Jan 2010

Information Technology Adoption In Latin American Microenterprises, Travis Good, Mehruz Kamal, Sajda Qureshi, Nancy Jimenez

Information Systems and Quantitative Analysis Faculty Proceedings & Presentations

The majority of businesses in developing regions across the world are microenterprises. In recent years, this form of business has been particularly resilient to economic downturns. While microenterprises are the least likely to succeed, when they do, their growth increases by a factor of 3.4% when they adopt technology. However, the challenges faced by microenterprises make it very difficult for them to adopt technology successfully. Existing theoretical models of ICT adoption have centered on intent to adopt in large organizations, and thus lack applicability to microenterprises, wherein the intent to adopt is an individual decision. This paper builds on prior …

Nonlinear Dynamic Analysis Of Mitral Valve Doppler Signals: Surrogate Data Analysis, Esma Uzunhi̇sarcikli Jan 2010

Nonlinear Dynamic Analysis Of Mitral Valve Doppler Signals: Surrogate Data Analysis, Esma Uzunhi̇sarcikli

Turkish Journal of Electrical Engineering and Computer Sciences

In our study, the nonlinear dynamics of mitral valve Doppler signals from 32 healthy and 28 patients with mitral valve stenosis was evaluated using by the computation of Lyapunov exponents, correlation dimension values and surrogate data analysis. Two chaotic features are compared for healthy and patient subjects. It was found that the largest Lyapunov exponent and correlation dimension values derived from patient subjects were larger than that of healthy subjects (\rho < 0.005). Surrogate data analysis was performed to determine the chaotic dynamics of Doppler signals. It was observed that the original and surrogate data have similar spectral features. Receiver operating characteristic (ROC) curves were used to evaluate the nonlinearity character Area Under the curve (AUC) values were obtained as 0.99 and 0.978 for the largest Lyapunov exponent and correlation dimension values, respectively. According to these results, Doppler signals have a nonlinear dynamic property and the largest Lyapunov exponent. Correlation dimension features can be used to detect the change in blood flow velocity of patients with mitral valve stenosis.

Real-Time Cinematic Design Of Visual Aspects In Computer-Generated Images, Juraj Obert Jan 2010

Real-Time Cinematic Design Of Visual Aspects In Computer-Generated Images, Juraj Obert

Electronic Theses and Dissertations

Creation of visually-pleasing images has always been one of the main goals of computer graphics. Two important components are necessary to achieve this goal --- artists who design visual aspects of an image (such as materials or lighting) and sophisticated algorithms that render the image. Traditionally, rendering has been of greater interest to researchers, while the design part has always been deemed as secondary. This has led to many inefficiencies, as artists, in order to create a stunning image, are often forced to resort to the traditional, creativity-baring, pipelines consisting of repeated rendering and parameter tweaking. Our work shifts the …

Spatio-Temporal Maximum Average Correlation Height Templates In Action Recognition And Video Summarization, Mikel Rodriguez Jan 2010

Spatio-Temporal Maximum Average Correlation Height Templates In Action Recognition And Video Summarization, Mikel Rodriguez

Electronic Theses and Dissertations

Action recognition represents one of the most difficult problems in computer vision given that it embodies the combination of several uncertain attributes, such as the subtle variability associated with individual human behavior and the challenges that come with viewpoint variations, scale changes and different temporal extents. Nevertheless, action recognition solutions are critical in a great number of domains, such video surveillance, assisted living environments, video search, interfaces, and virtual reality. In this dissertation, we investigate template-based action recognition algorithms that can incorporate the information contained in a set of training examples, and we explore how these algorithms perform in action …

Augmented Breast Tumor Classification By Perfusion Analysis, Bruce Yu-Sun Lin Jan 2010

Augmented Breast Tumor Classification By Perfusion Analysis, Bruce Yu-Sun Lin

LSU Doctoral Dissertations

Magnetic resonance and computed tomography imaging aid in the diagnosis and analysis of pathologic conditions. Blood flow, or perfusion, through a region of tissue can be computed from a time series of contrast-enhanced images. Perfusion is an important set of physiological parameters that reflect angiogenesis. In cancer, heightened angiogenesis is a key process in the growth and spread of tumorous masses. An automatic classification technique using recovered perfusion may prove to be a highly accurate diagnostic tool. Such a classification system would supplement existing histopathological tests, and help physicians to choose the most optimal treatment protocol. Perfusion is obtained through …

Applying The “Contextual Integrity” Model Of Privacy To Personal Blogs In The Blogoshere, Frances Grodzinsky, Herman T. Tavani Jan 2010

Applying The “Contextual Integrity” Model Of Privacy To Personal Blogs In The Blogoshere, Frances Grodzinsky, Herman T. Tavani

School of Computer Science & Engineering Faculty Publications

In this paper, we analyze some controversial aspects of blogging and the blogosphere from the perspective of privacy. In particular, we focus on Helen Nissenbaum’s theory of privacy as “contextual integrity” and apply it to personal blogs, in general, and the case of the “Washingtonienne” blogger, in particular. We examine the question of whether personal blogs that are not password protected can be considered “normatively private contexts” according to Nissenbaum’s principles of privacy. We argue that they cannot. Using Nissenbaum’s original model, we conclude that privacy expectations for those who disclose personal information in such blogs are unrealistic. We also …

An Adaptable Group Communication System, Vikram Reddy Kayathi Jan 2010

An Adaptable Group Communication System, Vikram Reddy Kayathi

LSU Master's Theses

Existing group communication systems like ISIS, Spread, Jgroups etc., provide group communication in a synchronous environment. They are built on top of TCP/IP or UDP and guarantee virtual synchrony and consistency. However, wide area distributed systems are inherently asynchronous. Existing group communication systems are not suitable for wide area deployment. They do not provide persistent communication; i.e., if a node gets temporarily disconnected, all messages directed to that node during that period are lost. Hence such systems are not suitable for deployment in disadvantaged networks. While, according to Brewer’s CAP theorem, it is impossible for a distributed computer system to …
