Developing A Distributed Java-Based Speech Recognition Engine, Tony Ayers, Brian Nolan 2017 Institute of Technology Blanchardstown

Developing A Distributed Java-Based Speech Recognition Engine, Tony Ayers, Brian Nolan

The ITB Journal

The development of speech recognition engines has traditionally been the territory of low-level development languages such as C. Until recently Java may not have been considered a candidate language for the development of such a speech engine, due to its security restrictions which limited its sound processing features. The release of the Java Sound API as part of the Java Media Framework and the subsequent integration of the Sound API into the standard Java development kit provides the necessary sound processing tools to Java to perform speech recognition. This paper documents our development of a speech recognition engine using the ...

Power Efficient High Temperature Asynchronous Microcontroller Design, Nathan William Kuhns

Theses and Dissertations

There is an increasing demand for dependable and efficient digital circuitry capable of operating in high temperature environments. Extreme temperatures have adverse effects on traditional silicon synchronous systems because of the changes in delay and setup and hold times caused by the variances in each device’s threshold voltage. This dissertation focuses on the design of the major functionality of an asynchronous 8051 microcontroller in Raytheon’s high temperature Silicon Carbide process, rated for operation over 300ºC. The microcontroller is designed in NULL Convention Logic, for which the traditional bus architecture used for data transfer would consume a large amount ...


Hexarray: A Novel Self-Reconfigurable Hardware System, Fady Hussein 2017 Boise State University

Hexarray: A Novel Self-Reconfigurable Hardware System, Fady Hussein

Boise State University Theses and Dissertations

Evolvable hardware (EHW) is a powerful autonomous system for adapting and finding solutions within a changing environment. EHW consists of two main components: a reconfigurable hardware core and an evolutionary algorithm. The majority of prior research focuses on improving either the reconfigurable hardware or the evolutionary algorithm in place, but not both. Thus, current implementations suffer from being application oriented and having slow reconfiguration times, low efficiencies, and less routing flexibility. In this work, a novel evolvable hardware platform is proposed that combines a novel reconfigurable hardware core and a novel evolutionary algorithm.

The proposed reconfigurable hardware core is a ...

Characterization Of Neural Network Backpropagation On Chiplet-Based Gpu Architectures, Colin A. Weinshenker 2017 College of William and Mary

Characterization Of Neural Network Backpropagation On Chiplet-Based Gpu Architectures, Colin A. Weinshenker

Undergraduate Honors Theses

Advances in parallel computing architectures (e.g., Graphics Processing Units (GPUs)) have had great success in helping meet the performance and energy-efficiency demands of many high-performance computing (HPC) applications. DRAM bandwidth is generally a critical performance bottleneck for many of such applications. With the advances in memory technology, the DRAM bandwidth bottleneck is shifting towards other parts of the system hierarchy (e.g., interconnects). We identify neural network backpropagation as one application where the interconnect network is one of the biggest performance bottlenecks. We show that the interconnect bottleneck for backpropagation can be significantly alleviated if computing cores and caching ...


Metafork: A Compilation Framework For Concurrency Models Targeting Hardware Accelerators, Xiaohui Chen 2017 The University of Western Ontario

Metafork: A Compilation Framework For Concurrency Models Targeting Hardware Accelerators, Xiaohui Chen

Electronic Thesis and Dissertation Repository

Parallel programming is gaining ground in various domains due to the tremendous computational power that it brings; however, it also requires a substantial code crafting effort to achieve performance improvement. Unfortunately, in most cases, performance tuning has to be accomplished manually by programmers. We argue that automated tuning is necessary due to the combination of the following factors. First, code optimization is machine-dependent. That is, optimization preferred on one machine may be not suitable for another machine. Second, as the possible optimization search space increases, manually finding an optimized configuration is hard. Therefore, developing new compiler techniques for optimizing applications ...


Funny Games - A Definition For And Study Of Comic Videogames, Eric Guardara 2017 Long Island University

Funny Games - A Definition For And Study Of Comic Videogames, Eric Guardara

Post & Beyond

In this project, I define the genre of Comic Games and discuss its categorical independence of other genres. Until now, this genre has not been clearly defined in the videogame medium. I have conducted research and compiled games that are generally accepted as being humorous. I then weeded out games that simply contain humor and categorized the remaining works that are at their core Comic Games. Comic Games are those whose primary and prolonged purpose are to evoke laughter from the user. This is different than humorous games that passively include humor. A Comic Game is one that is predominantly ...

Promoting Information Resources To Students: Using Wordpress To Maintain Library Data Sets, Derek Stadler 2017 CUNY La Guardia Community College

Promoting Information Resources To Students: Using Wordpress To Maintain Library Data Sets, Derek Stadler

Publications and Research

Although it began as a blog tool, WordPress has grown into a complete content management system with thousands of interactive themes available. Since it uses the MySQL database management system, the open-source software suits the needs of library websites by aggregating a college library’s complete database inventory. Rather than update several HTML pages within a site when new vendors are added or a URL is changed, information from vendors can be maintained in a database table and then displayed to students, highlighting available resources and information. The presentation highlights the use of some simple WordPress plugins to manage many ...


Contextual Model-Based Collaborative Filtering For Recommender Systems, Dennis E. Bachmann 2017 The University of Western Ontario

Contextual Model-Based Collaborative Filtering For Recommender Systems, Dennis E. Bachmann

Electronic Thesis and Dissertation Repository

Recommender systems have dramatically changed the way we consume content. Internet applications rely on these systems to help users navigate among the ever-increasing number of choices available. However, most current systems ignore that user preferences can change according to context, resulting in recommendations that do not fit user interests. Context-aware models have been proposed to address this issue, but these models have problems of their own. The ever-increasing speed at which data are generated presents a scalability challenge for single-model approaches. Moreover, the complexity of these models prevents small players from adapting and implementing contextual models that meet their needs ...

Generating A Normalized Database Using Class Normalization, Daniel Sushil Sudhindaran

UNF Theses and Dissertations

Relational databases are the most popular databases used by enterprise applications to store persistent data to this day. It gives a lot of flexibility and efficiency. A process called database normalization helps make sure that the database is free from redundancies and update anomalies. In a Database-First approach to software development, the database is designed first, and then an Object-Relational Mapping (ORM) tool is used to generate the programming classes (data layer) to interact with the database. Finally, the business logic code is written to interact with the data layer to persist the business data to the database. However, in ...
