Agent-Based Architecture for Web Deployment of Multi-Agents as Conversational Interfaces.

Description: Agent-based architecture explains the rationale and basis for developing agents that can interact with users through natural language query/answer patterns developed systematically using AIML (artificial intelligence mark-up language) scripts. This thesis research document also explains the architecture for VISTA (virtual interactive story-telling agents), which is used for interactive querying in educational and recreational purposes. Agents are very effective as conversational interfaces when… more

Analysis and expression of the cotton gene for the D-12 fatty acid desaturases 2-4 (FAD2-4)

Description: A genomic clone containing a 16.9-kb segment of cotton DNA was found to encompass a D-12 fatty acid desaturases (FAD2-4) gene. The FAD2-4 gene has a single, large intron of 2,780 bp in its 5'-untranslated region, just 12 bp upstream from the ATG initiation codon of the FAD2-4 opening reading frame. A number of prospective promoter elements, including several light-responsive sequences, occur in the 5'-flanking region. The coding region of the gene is 1155 bp with no introns, and would encode… more

Analysis of Japanese Exports and Imports of Rice

Description: This research shows that the Japanese rice policy has affected the volume of exported and imported rice; moreover, multilateral and bilateral agreements have also affected Japanese rice policy. Japan's institution of subsidies and trade barriers has made its rice products too expensive for foreign trade and its domestic consumers. Since the WTO agreement has forced Japan to open its market gradually over six years, Japan may be unable to compete internationally because of its limited land, high… more

Ballistic Deposition: Global Scaling and Local Time Series.

Description: Complexity can emerge from extremely simple rules. A paradigmatic example of this is the model of ballistic deposition (BD), a simple model of sedimentary rock growth. In two separate Problem-in-Lieu-of Thesis studies, BD was investigated numerically in (1+1)-D on a lattice. Both studies are combined in this document. For problem I, the global interface roughening (IR) process was studied in terms of effective scaling exponents for a generalized BD model. The model used incorporates a tunable p… more

Benchmark-based Page Replacement (BBPR) Strategy: A New Web Cache Page Replacement Strategy

Description: World Wide Web caching is widely used through today's Internet. When correctly deployed, Web caching systems can lead to significant bandwidth savings, network load reduction, server load balancing, and higher content availability. A document replacement algorithm that can lower retrieval latency and yield high hit ratio is the key to the effectiveness of proxy caches. More than twenty cache algorithms have been employed in academic studies and in corporate communities as well. But there are so… more

Content-Based Image Retrieval by Integration of Metadata Encoded Multimedia Features in Constructing a Video Summarizer Application.

Description: Content-based image retrieval (CBIR) is the retrieval of images from a collection by means of internal feature measures of the information content of the images. In CBIR systems, text media is usually used only to retrieve exemplar images for further searching by image feature content. This research work describes a new method for integrating multimedia text and image content features to increase the retrieval performance of the system. I am exploring the content-based features of an image extr… more

Deposition and Characterization of Pentacene Film.

Description: Many organic materials have been studied to be used as semiconductors, few of them being pentacene and polythiophene. Organic semiconductors have been investigated to make organic thin film transistors. Pentacene has been used in the active region of the transistors. Transistors fabricated with pentacene do not have very high mobility. But in some applications, high mobility is not needed. In such application other properties of organic transistors are used, such as, ease of production and flex… more

DICOM Image Scrubbing Software Library/Utility

Description: This software is aimed at providing user-friendly, easy-to-use environment for the user to scrub (de-identify/modify) the DICOM header information. Some tools either anonymize or default the values without the user interaction. The user doesn't have the flexibility to edit the header information. One cannot scrub set of images simultaneously (batch scrubbing). This motivated to develop a tool/utility that can scrub a set of images in a single step more efficiently. This document also addresses … more

Enigmatic Realms

Description: The use of copper in my work has opened up an entirely new conceptual and esthetic world. I have expanded my vocabulary of visual imagery based on the nature of how copper reacts with fire. The organic beauty harmonizes so gracefully with the manufactured material. This new material has certainly opened up a refreshing platform on which to further develop my ideas.

Fashion Circles

Description: Through this body of work and this paper the possibilities of using Fashion Design to express the concepts of the circle has been explored. This was done with three questions in mind: How can I use the shape of the circle as inspiration for fashion design? How can I express related words and phrases in my design? and How can I use the colors black and white to emphasize the concept of my design. To answer these questions I have created two groups of garments: one was inspired by circular object… more

The Feasibility of Multicasting in RMI

Description: Due to the growing need of the Internet and networking technologies, simple, powerful, easily maintained distributed applications needed to be developed. These kinds of applications can benefit greatly from distributed computing concepts. Despite its powerful mechanisms, Jini has yet to be accepted in mainstream Java development. Until that happens, we need to find better Remote Method Invocation (RMI) solutions. Feasibility of implementation of Multicasting in RMI is worked in this paper. Mult… more

Industrial Landscapes: Humanity Coexisting with Nature

Description: The focus of this project was on creating images of our industrial landscape and shows the coexistence of culture and nature. I confronted the landscape from a position that is accepting of our present landscape. While not idealizing the present industrial landscape I wanted to depict it in a way that is not devoid of beauty. I believe that no matter how the land is altered a certain grace still comes through in any landscape. In not idealizing or criticizing I wanted to show industrial areas i… more

Organic Revelations

Description: Recently my creative process has led to a new area of investigation and exploration. I have discovered that I enjoy the unexpected occurrences that happen while painting. I have an appreciation for the parts of my works that do not follow the preliminary sketch and are produced more subconsciously. While usually this aspect has been restricted by the adherence to a preliminary sketch and narrative, the new works explore these occurrences more fully. In the new works, I worked in a more spontane… more
