Chinese To English Introductory Cover Letter Generator, Jason L. Stine

Liberal Arts and Engineering Studies

The Chinese to English Introductory Cover Letter Generator allows Chinese computer users who know little to no English automatically generate a self-introductory cover letter in good English. As an example, professors in English-speaking countries are increasingly receiving emails from students abroad in countries like China, and these students often need to introduce themselves in order to support their reasons for their message. Unfortunately, more often than not these letters contain poorly written English. This software aims to help solve this issue. Using a combination of a “sentence template” system and intelligent natural language processing software, the program assembles each paragraph …

Active Pen Input And The Android Input Framework, Andrew S. Hughes

Master's Theses

User input has taken many forms since the conception of computers. In the past ten years, Tablet PCs have provided a natural writing experience for users with the advent of active pen input. Unfortunately, pen based input has yet to be adopted as an input method by any modern mobile operating system. This thesis investigates the addition of active pen based input to the Android mobile operating system.

The Android input framework was evaluated and modified to allow for active pen input events. Since active pens allow for their position to be detected without making contact with the screen, an …

Flexible Tuning Software: Beyond Equal Temperament, Erica Sponsler

Renée Crown University Honors Thesis Projects - All

The premise of this creative Capstone project was to develop a computer instrument that is capable of tuning itself flexibly in such a way as to not require a tempering of the Western scale, as is necessary for fixedly tuned instruments. The difficulty in creating such a system of tuning arises from the mathematical paradox of the musical harmonic series, which is the sequence of frequencies that sound naturally as overtones over a fundamental pitch. They follow a proportional pattern of 1:2, 2:3, 3:4, etc. These small-integer ratios of frequencies represent the consonant (in-tune) harmonic intervals. When an interval does …

A Wireless Sensor Network For Monitoring Physical Activity, Physiological Response, And Environmental Conditions, Michael Leon Pook

Boise State University Theses and Dissertations

Understanding movement is an important area of research for improving comfort and safety. Data collected from accelerometers and gyros attached to multiple parts of a body can be used to determine the type of physical activity in which an individual is engaging. Correlating this data with the individual's heart rate allows for the verification of the type of activity as well as observation of the amount of physical strain experienced during the activity. Additionally, data on environmental stimuli can be gathered in order to determine their effect on physical strain. Current research in the field has been limited by both …

Non-Blocking Hardware Coding For Embedded Systems, Derek Caleb Klein

Boise State University Theses and Dissertations

Embedded Systems can be found in devices that people use every day. In the pursuit of faster and smarter devices, more powerful processing units are needed in these embedded systems. A key component of powerful processing units is the supporting software. While the raw processing power of microcontroller has been continually advancing, the improvements in the supporting software for medium scale embedded systems have been lacking. This thesis focuses on improving the software on medium scale systems by discussing the practical application of non-blocking coding techniques. The basic concept of how non-blocking code improves the performance of a system is …

Reconfigurable Systems: A Potential Solution To The Von Neumann Bottleneck, Damian L. Miller

Senior Honors Theses

The difficulty of overcoming the disparity between processor speeds and data access speeds, a condition known as the von Neumann bottleneck, has been a source of consternation for computer hardware developers for many years.  Although a number of temporary solutions have been proposed and implemented in modern machines, these solutions have only managed to treat the major symptoms, rather than solve the root problem.  As the number of transistors on a chip roughly doubles every two years, the von Neumann bottleneck has continued to tighten in spite of these solutions, prompting some computer hardware professionals to advocate a paradigm shift …

Gpu-Based Global Illumination Using Lightcuts, Tong Zhang

Department of Computer Graphics Technology Degree Theses

Global Illumination aims to generate high quality images. But due to its high
requirements, it is usually quite slow. Research documented in this thesis was
intended to offer a hardware and software combined acceleration solution to
global illumination. The GPU (using CUDA) was the hardware part of the whole
method that applied parallelism to increase performance; the “Lightcuts”
algorithm proposed by Walter (2005) at SIGGRAPH 2005 acted as the software
method. As the results demonstrated in this thesis, this combined method offers
a satisfactory performance boost effect for relatively complex scenes.

Polygonal Spatial Clustering, Deepti Joshi

School of Computing: Dissertations, Theses, and Student Research

Clustering, the process of grouping together similar objects, is a fundamental task in data mining to help perform knowledge discovery in large datasets.  With the growing number of sensor networks, geospatial satellites, global positioning devices, and human networks tremendous amounts of spatio-temporal data that measure the state of the planet Earth are being collected every day.  This large amount of spatio-temporal data has increased the need for efficient spatial data mining techniques.  Furthermore, most of the anthropogenic objects in space are represented using polygons, for example – counties, census tracts, and watersheds.  Therefore, it is important to develop data mining …

Overcoming Pose Limitations Of A Skin-Cued Histograms Of Oriented Gradients Dismount Detector Through Contextual Use Of Skin Islands And Multiple Support Vector Machines, Jonathon R. Climer

Theses and Dissertations

This thesis provides a novel visualization method to analyze the impact that articulations in dismount pose and camera aspect angle have on histograms of oriented gradients (HOG) features and eventual detections. Insights from these relationships are used to identify limitations in a state of the art skin cued HOG dismount detector's ability to detect poses not in a standard upright stances. Improvements to detector performance are made by further leveraging available skin information, reducing false detections by an additional order of magnitude. In addition, a method is outlined for training supplemental support vector machines (SVMs) from computer generated data, for …

Virtual Battlespace Behavior Generation Through Class Imitation, Bryon K. Fryer Jr.

Theses and Dissertations

Military organizations need realistic training scenarios to ensure mission readiness. Developing the skills required to differentiate combatants from non-combatants is very important for ensuring the international law of armed conflict is upheld. In Simulated Training Environments, one of the open challenges is to correctly simulate the appearance and behavior of combatant and non-combatant agents in a realistic manner. This thesis outlines the construction of a data driven agent that is capable of imitating the behaviors of the Virtual BattleSpace 2 behavior classes while our agent is configured to advance to a geographically specific goal. The approach and the resulting agent …

An Architecture For Improving Timeliness And Relevance Of Cyber Incident Notifications, James L. Miller

Theses and Dissertations

This research proposes a communications architecture to deliver timely and relevant cyber incident notifications to dependent mission stakeholders. This architecture, modeled in Unified Modeling Language (UML), eschews the traditional method of pushing notifications via message as dictated in Air Force Instruction 33-138. It instead shifts to a pull or publish and subscribe method of making notifications. Shifting this paradigm improves the notification process by empowering mission owners to identify those resources on which they depend for mission accomplishment, provides a direct conduit between providing and dependent mission owners for notifications when an incident occurs, and provides a shared representation for …

Simultaneous Range/Velocity Detection With An Ultra-Wideband Random Noise Radar Through Fully Digital Cross-Correlation In The Time Domain, James R. Lievsay

Theses and Dissertations

This research effort examines the theory, application, and results of applying two-dimensional cross-correlation in the time domain to ultra-wideband (UWB) random noise waveforms for simultaneous range and velocity estimation. When applying common Doppler processing techniques to random noise waveforms for the purpose of velocity estimation, the velocity resolution degrades as the signal bandwidth or the target speed increase. To mitigate the degradation, the Doppler approximation is not utilized, and instead, wideband signal processing theory is applied in the time domain. The results show that by accurately interpolating each sample in the digitized reference signal, a target's velocity and range can …

The State Of Software Engineering Maturity And Licensure, Travis Lawrence Dean

Master's Theses

IEEE-CS is pursuing licensing for software engineers, but ACM believes that software engineering is too immature, and regulating the profession would be premature. In 1996, Norman Gibbs and Gary Ford from Carnegie Mellon University performed a qualitative survey of the maturity of the software engineering profession. I apply this model to the present state of the art in software engineering and analyze the results for 2010. I analyze the maturity of software engineering to determine that the profession is not yet ready for licensure. This is not because the infrastructure of software engineering is too immature, but because we have …

Data Mining Based Learning Algorithms For Semi-Supervised Object Identification And Tracking, Michael P. Dessauer

Doctoral Dissertations

Sensor exploitation (SE) is the crucial step in surveillance applications such as airport security and search and rescue operations. It allows localization and identification of movement in urban settings and can significantly boost knowledge gathering, interpretation and action. Data mining techniques offer the promise of precise and accurate knowledge acquisition techniques in high-dimensional data domains (and diminishing the “curse of dimensionality” prevalent in such datasets), coupled by algorithmic design in feature extraction, discriminative ranking, feature fusion and supervised learning (classification). Consequently, data mining techniques and algorithms can be used to refine and process captured data and to detect, recognize, classify, …

The scope of this investigation is confined to a staring sensor that records data of sub-pixel vehicles traveling horizontally across the ground. Statistical models of the targets and background are developed with noise and jitter effects. Threshold Change Detection, Duration Change Detection and Fast Adaptive Power Iteration (FAPI) Detection …

A New Approach To Algebraic Coding Theory Through The Applications Of Soft Sets, Florentin Smarandache, Mumtaz Ali

Branch Mathematics and Statistics Faculty and Staff Publications

Algebraic codes play a signifcant role in the minimisation of data corruption which caused by defects such as inference, noise channel, crosstalk, and packet loss. In this paper, we introduce soft codes (soft linear codes) through the application of soft sets which is an approximated collection of codes. We also discuss several types of soft codes such as type-1 soft codes, complete soft codes etc. Further, we construct the soft generator matrix and soft parity check matrix for the soft linear codes. Moreover, we develop two techniques for the decoding of soft codes.

Evidence Supporting Measure Of Similarity For Reducing The Complexity In Information Fusion, Florentin Smarandache, Jean Dezert, Xinde Li, Xinhan Huang

Branch Mathematics and Statistics Faculty and Staff Publications

This paper presents a new method for reducing the number of sources of evidence to combine in order to reduce the complexity of the fusion processing. Such a complexity reduction is often required in many applications where the real-time constraint and limited computing resources are of prime importance. The basic idea consists in selecting, among all sources available, only a subset of sources of evidence to combine. The selection is based on an evidence supporting measure of similarity (ESMS) criterion which is an efficient generic tool for outlier sources identification and rejection. The ESMS between two sources of evidence can …

Evidence Supporting Measure Of Similarity For Reducing The Complexity In Information Fusion, Xinde Li, Jean Dezert, Florentin Smarandache, Xinhan Huang

Branch Mathematics and Statistics Faculty and Staff Publications

This paper proposes a new solution for reducing the number of sources of evidence to be combined in order to diminish the complexity of the fusion process required in some applications where the real-time constraint and strong computing resource limitation are of prime importance. The basic idea consists in selecting, among the whole set of sources of evidence, only the biggest subset of sources which are not too contradicting based on a criterion of Evidence Supporting Measure of Similarity (ESMS) in order to process solely the coherent information received. The ESMS criterion serves actually as a generic tool for outlier …
