Fundamental Concepts in Electrical and Computer Engineering with Practical Design Problems

Second Edition

by Reza Adhami, Peter M. Meenen, III, and Dennis Hite

2007

In many cases, the beginning engineering student is thrown into upper-level engineering courses without an adequate introduction to the basic material. This, at best, causes undue stress on the student as they feel unprepared when faced with unfamiliar material, and at worst, results in students dropping out of the program or changing majors when they discover that their chosen field of engineering is not what they thought it was. The purpose of this text is to introduce the student to a general cross-section of the field of electrical and computer engineering. The text is aimed at incoming freshmen, and as such, assumes that the reader has a limited to nonexistent background in electrical engineering and knowledge of no more than pre-calculus in the field of mathematics. By exposing s...

Vision-based Robot Navigation

Quest for Intelligent Approaches Using a Sparse Distributed Memory

by Mateus Mendes, A. Paulo Coimbra, & Manuel M. Crisostomo

2012

Starting with a summary of the history of Artificial Intelligence, this book makes the bridge to the modern debate on the definition of Intelligence and the path to building Intelligent Machines. Since the definition of Intelligence is itself subject to open debate, the quest for Intelligent machines is pursuing a moving target. Apparently, intelligent behaviour is, to a great extent, the result of using a sophisticated associative memory, more than the result of heavy processing. The book describes theories on how the brain works, associative memory models and how a particular model - the Sparse Distributed Memory (SDM) - can be used to navigate a robot based on visual memories. Other robot navigation methods are also comprehensively revised and compared to the method proposed. The per...

Head-Order Techniques and Other Pragmatics of Lambda Calculus Graph Reduction

by Nikos B. Troullinos

2011

The operational aspects of Lambda Calculus are studied as a fundamental basis for high-order functional computation. We consider systems having full reduction semantics, i.e., equivalence-preserving transformations of functions. The historic lineage from Eval-Apply to SECD to RTNF/RTLF culminates in the techniques of normal-order graph Head Order Reduction (HOR). By using a scalar mechanism to artificially bind relatively free variables, HOR makes it relatively effortless to reduce expressions beyond weak normal form and to allow expression-level results while exhibiting a well-behaved linear self-modifying code structure. Several variations of HOR are presented and compared to other efficient reducers, with and without sharing, including a conservative breadth-first one which mechanically...

Performance Evaluation of Vision Algorithms on FPGA

by Mahendra Gunathilaka Samarawickrama

2010

The modern FPGAs enable system designers to develop high-performance computing (HPC) applications with a large amount of parallelism. Real-time image processing is such a requirement that demands much more processing power than a conventional processor can deliver. In this research, we implemented software and hardware based architectures on FPGA to achieve real-time image processing. Furthermore, we benchmark and compare our implemented architectures with existing architectures. The operational structures of those systems consist of on-chip processors or custom vision coprocessors implemented in a parallel manner with efficient memory and bus architectures. The performance properties such as the accuracy, throughput and efficiency are measured and presented. According to results, FPGA ...

Arduino for the Cloud

Arduino Yun and Dragino Yun Shield

by Claus Kuhnel

2015

Arduino for the Cloud considers the Arduino Yun and the Dragino Yun Shield as components closing the gap between a typical microcontroller application and connection to the cloud. Arduino Yun combines the classic Arduino with an Atheros AR9331 system-on-a-chip (SoC) for wireless access points and routers platforms, which uses the Linux distribution Linino (OpenWRT) operating system. The Dragino Yun Shield expands any Arduino with network capabilities by the Atheros AR9331.The combination of microcontroller and Linux device supports the whole chain from sensor to software applications in the cloud by hardware and software. This book deals with the Arduino and the Linux device and their interaction, without the need of detailed Linux knowledge.

Visualization of Interface Metaphor for Software

An Engineering Approach

by Dinesh S. Katre

2011

This book presents a comprehensive process for visualization of interface metaphor for software. It is helpful in designing interactive user interfaces with magical super-affordances and definitive user experiences. As per the ancient Indian Vedic literature, metaphors are always conceived out of Vastu (entities having existence in our world). The visualization process given in the book shows how metaphorization could help in innovating highly experiential user interfaces, as one can create Avastu (non entities) by combining different objects and imaginative properties together. The main highlights of this process are selection and dissection of interface metaphor, pre-facto analysis, qualitative and quantitative evaluation, mapping between user and application domain lexicons, specialized...

R^² - Heaps with Suspended Relaxation for Manipulating Priority Queues and a New Algorithm for Reweighting Graphs

by Ruth Shrairman

2004

This research is dedicated to two main problems in finding shortest paths in the graphs. The first problem is to find shortest paths from an origin to all other vertices in non-negatively weighted graph. The second problem is the same, except it is allowed that some edges are negative. This is a more difficult problem that can be solved by relatively complicated algorithms. We attack the first problem by introducing a new data structure - Relaxed Heaps that implements efficiently two main operations critical for the improvement of Dijkstra's shortest path algorithm. R²heaps with suspended relaxation proposed in this research gives the best known worst-case time bounds of O(1) for a decrease_key operation and O(logn) for a delete_min operation. That results in the best worst-case running...

Acquisition and Reproduction of Color Images

Colorimetric and Multispectral Approaches

by Jon Hardeberg

2001

The goal of the work reported in this dissertation is to develop methods for the acquisition and reproduction of high quality digital color images. To reach this goal it is necessary to understand and control the way in which the different devices involved in the entire color imaging chain treat colors. Therefore we addressed the problem of colorimetric characterization of scanners and printers, providing efficient and colorimetrically accurate means of conversion between a device-independent color space such as the CIELAB space, and the device-dependent color spaces of a scanner and a printer. First, we propose a new method for the colorimetric characterization of color scanners. It consists of applying a non-linear correction to the scanner RGB values followed by a 3rd order 3D polynom...

The ALISA Shape Module

Adaptive Shape Recognition using a Radial Feature Token

by Glenn C. Becker

2002

Shape classification is a challenging image processing problem because shapes can occur in any position, at any orientation, and at any scale in an image. Shapes can also be obscured by gaps in their boundaries, occlusions, and noise. General shape classifiers often suffer from low precision, and specialized shape classifiers rely on specific features, like vertices or connected boundaries, making them difficult to generalize. The objective of this research is to design, implement, and test a general, high-precision two-dimensional shape classifier that is invariant to translation, scale, and rotation, as well as robust to gaps in the shape boundary, occlusions, and noise. To achieve this objective, the radial feature token (RFT) is implemented as the ALISA Shape Module, which learns to cl...

Oracle DBA 101

A Beginner’s Guide

by Rao R. Uppaluri

2000

There is a dearth of Oracle Database Administrators inspite of having a large number of Oracle Programmers/Analysts. It is not difficult to rationalise the reason for this. Oracle Database Administration (DBA) is relatively harder to grasp and the concepts are subtle. There are a handful of books, all exhaustive treatises, on this topic, in addition to those by Oracle Corporation. There are no elementary books to smoothly introduce this fascinating topic. The present book, "Oracle DBA 101: A Beginner’s Guide" is expected to fill this vital gap. At the beginner’s level, it deals with all important aspects of Oracle DBA in a simplified manner. This is a Teacher’s as well as Student’s tool for an introductory course on the topic.

2020 Web Vision

How the Internet will Revolutionize Future Homes, Business and Society

by Robert D. Oberst

2001

At the dawn of a new millennium, faith in technology soared following the successful eradication of the potentially paralyzing Y2K bug. Young dot-coms with little experience and possessing few assets other than a concept, flourished boasting market values in the millions and even billions of dollars. Then reality settled in as the market crashed and over a hundred dot-coms perished. The highflying NASDAQ dropped over 60% and the longest economic expansion teetered on the brink of recession. Despite the disconcerting scenario, this was not the demise of the Web, but merely the conclusion of its innocent childhood or the first stage of meteoric growth. After all, the Web was only 10 years old. There were still trillions of dollars worth of opportunities, as the more rigorous applicatio...

In the last ten years there has been an explosion in the use of computer technology in many facets of our lives. Many industries such as finance, manufacturing, and retail have embraced modern technological advances through the use of advanced computer and telecommunication technology. Unfortunately, the international health care community has been quite slow to effectively integrate new computer technology into the daily care of patients. Nevertheless, governments across the world are developing strategic plans and allocating financial resources to support the use of technology in healthcare. Medical Informatics Around The World: An International Perspective Focusing On Training Issues provides a global snapshot into such activities in 13 different countries (Australia, China, Hong Ko...

An Evaluation of Computer Based Training for Police Radar Operators

by Paul E. Konschak

2003

The purpose of this study was to examine two instructional methods for delivering a radar operators training class for members of a municipal police department. The first method examined was the traditional classroom-based training with a certified radar instructor. The second method was a computer-based training (CBT) course based on the instructional material from the classroom-based course. The CBT course was administered on CD-ROM using the police department s Windows© based computers. This study compared the two methods of delivery to determine if the CBT course was as effective as the traditional classroom-based course.Effectiveness was measured by the completion times of the two courses, examination scores, and overall participant satisfaction levels. These measures were conducted u...

Gesture Generation by Imitation

From Human Behavior to Computer Character Animation

by Michael Kipp

2005

In an effort to extend traditional human-computer interfaces research has introduced embodied agents to utilize the modalities of everyday human-human communication, like facial expression, gestures and body postures. However, giving computer agents a human-like body introduces new challenges. Since human users are very sensitive and critical concerning bodily behavior the agents must act naturally and individually in order to be believable. This dissertation focuses on conversational gestures. It shows how to generate conversational gestures for an animated embodied agent based on annotated text input. The central idea is to imitate the gestural behavior of a human individual. Using TV show recordings as empirical data, gestural key parameters are extracte...

Success Factors Among Community College Students in an Online Learning Environment

by Paula B. Doherty

2000

Little is known about student success in online learning environments, especially how the predisposing characteristics that the learner brings to the learning environment may differentially affect student outcomes. This study explored the question of whether a student's "readiness" to be a self-directed learner is a predictor of student success in an online community college curriculum. The specific goal of this investigation was to determine whether there was a significant relationship between self-directed learning readiness-as measured by Guglielmino's (1977) Self-Directed Learning Readiness Scale (SDLRS)- and student success-as measured by course completion, grade point average (GPA) and student satisfaction, the latter assessed by student responses to an opinion poll. The subject...

Effects of Computer-Based Cooperative Learning on the Problem Solving Skills of Grade Six Students

by Steven Poris

2000

This study was designed to determine if sixth-grade students' problem solving skills were improved by means of their experience with a computer-based logical puzzle game designed to increase reasoning skills, and, in turn, problem solving ability. Students worked on this game either in cooperative learning pairs or alone. Baseline and post-experimental problem-solving ability was measured through the administration of a Problem Solving Test; Form A was utilized as a pretest for this purpose, Form B was used as a post-test. Comparisons of problem-solving ability based upon post-test scores (Form B) were made among four groups of students (N = 106): Group 1: Students (n = 26) who worked on the computer-based puzzle game in cooperative learning pairs Group 2: Students (n = 27) ...

Displacement Mapping and Volume Rendering Graphics Hardware

by Michael C. Doggett

2002

This dissertation introduces new hardware architectures for more realistic surface rendering of three dimensional objects and the rendering of volumetric datasets. Surface rendering is dealt with in the first part of the dissertation where the architectures for displacement map rendering in hardware are proposed. This work represents the first to appear in scientific literature on displacement map hardware rendering. Where possible these architectures propose components that integrate into currently available pipelines and make use of existing units in those pipelines. Displacement map rendering in hardware is a desired feature currently under development by most graphics hardware vendors. The first architecture is scan-line based and works just before rasterization and the second adaptiv...

Software-Agents and Liberal Order

An Inquiry along the Borderline between Economics and Computer Science

by Dirk N Wagner

2000

"Liberal order and software-agents" - long-established ideas and modern technology are bridged. The impulse for undertaking this effort comes from the observation that it becomes difficult for computer science alone to create order for and within machines. The growing complexity of computer systems, open networks like the Internet, and the increasingly social role of software entities push the traditional quest for total global control out of reach. Economic theory of social order offers extensive experience with such conditions, so that it can complement and guide research in computer science. It is shown that a common understanding between economics and computer science's sub-field of distributed artificial intelligence is possible on the level of software-agents. On this basis, four fun...

A Reactive Approach to Comprehensive Global Garbage Detection

by Sylvain R Y Louboutin

1999

Comprehensive global garbage detection (GGD) in object-oriented distributed systems, i.e., GGD intrinsically able to detect distributed cycles of garbage, has mostly been addressed via graph tracing algorithms. Graph tracing algorithms must account for every live object in the system before any resource can actually be reclaimed which compromises both their scalability and robustness in a distributed environment. Alternative non-comprehensive approaches trade-off comprehensiveness for scalability and robustness under the assumptions that distributed cycles of garbage are rare and that all comprehensive algorithms are necessarily unscalable. This thesis contends instead that distributed cycles of garbage are as likely to occur as local cycles and that a comprehensive alternative to g...

Separating Data from Instructions

Investigating a New Programming Paradigm

by Yasushi Kambayashi

2002

We have experienced different theories of software construction paradigms in the last few decades; such as "structured programming" in the 1970's and "object-oriented programming" in the 1980's. The object-oriented paradigm is considered a standard for many software development activities, from the analysis phase to various support phases. There is little quantitative research, however, regarding the question whether object-oriented programming improves productivity. Many assume that object-oriented programming is more productive than traditional structured programming. This assumption lacks concrete, empirical data that support such belief. This dissertation identifies problems in the current object-oriented programming practice, and then presents an alternative paradigm to help overcome ...

by Maria Mercedes T. Rodrigo

2003

Both public and private schools in the Philippines are using information technology (IT) as a tool to improve teaching and learning. While both government and private sector initiatives indicate national commitment to IT in education, there is little up-to-date information on how extensively the Philippines are using computers and for what purposes. The researcher s goals were to determine the extent to which Metro Manila public and private schools used IT and to determine how these results compared with analogous data on schools in other developing and developed countries. The researcher gathered data with mail-in questionnaires adapted from the International Assoc...

A Model of Freshman Use of Microcomputers Related to Intellectual and Social Development

by Daniel R. Judd

2002

The purpose of this study was to determine the relationship between freshmen's use of microcomputers and their social and intellectual development in a university environment. A review of related literature describes the theoretical foundation of this research and identifies questionnaire items for measuring the critical variables of microcomputer use and student development. To conduct the study, data obtained from 400 freshman students prior to entering Utah State University (USU) in the fall of 1996 were compared to data collected from the same students during Spring Quarter of 1997.

Correlation Between Levels of Depression and Time Spent in Communications Activities, Information-gathering Activities, and Personal Transactions

by Marie Napoli

2000

This dissertation studied the correlation between the number of hours spent by seniors on the internet in three categories of online activities and the seniors' levels of depression. The subjects were men and women age fifty-five and older living in an active retirement community. The three categories of online activities were communications activities, information-gathering activities, and personal transactions. Number of hours spent online was measured by a self-reporting questionnaire. Level of depression was measured by administration of the Beck Depression Inventory-II. Spearman's rho was used as the correlation coefficient. Level of significance was .05. No significant correlation was found between the variable level of depression and the three categories of online activities. Fur...

Application of Scheduling Theory to Spacecraft Constellations

by Christopher J. Graham

2000

In this thesis we advance the state-of the practice in the Space Mission Operations domain by leveraging single spacecraft technologies along with classical scheduling frameworks and notation to create a scheduler for a constellation of spacecraft. We define a scheduling product that is focused on the problem of scheduling networked groups of spacecraft, called constellations. Within this thesis we show that the constellation schedule problem is a very complex problem, and the application of heuristics is one approach that allow us to schedule successfully. Our first objective, comprising chapters 1, 2, and 3, is to describe the spacecraft constellation domain and the objectives of the thesis. This background provides a foundation for understanding the constellation scheduling problem doma...

Information Theoretic Approach to Logic Functions Minimization

by Denis V. Popel

2000

Information theory methods are of wide use in contemporary logic design, but their proper application to Computer Aided Design (CAD) is rather impossible without strong theoretical and practical justification. Our research is focused on logic function minimization which is an essential component of any system for digital circuit design. The well-known information theory methods to minimize logic functions should be improved and developed towards new problems appeared while increasing the number of CAD applications. We report new results on logic functions minimization by information theory standpoint. We have developed an information theoretic model of recursive decomposition of logic functions. Based on this model, a novel technique for efficient Decision Tree design of various types (AND...

An IT and Security Comparison Decision Support System for Wireless LANs

802.11 infosec and WiFi LAN comparison

by Kevin T. Reynolds, CISSP, PMP

2004

Are all Wireless LANs equal? A network administrator is faced with a plethora of wireless services, complex radio issues, and products for wireless data. There are brand new protocols and products that could become obsolete a day after installation! Over 40% of all deployed WLANs do not even have minimum security activated, exposing the company's network and records to easy outsider access.The WLAN industry is characterized by rapidly changing, incomplete or proprietary standards, which can impact interoperability goals. There are complicated ownership costs, performance limitations, and security configurations that exist for WLANs which many network administrators may not understand or know how to compare. This dissertation presents a decision support system (DSS) that enables a nov...

Context Mediation among Knowledge Discovery Components

by Alex Buchner

2004

Context Mediation is a field of research that is concerned with the interchange of information across different environments, which provides a vehicle to bridge semantic gaps among disparate entities. Knowledge Discovery is concerned with the extraction of actionable information from large databases. A challenge that has received relatively little attention is knowledge discovery in a highly disparate environment, that is multiple heterogeneous data sources, multiple domain knowledge sources and multiple knowledge patterns. This thesis tackles the problem of semantic interoperability among data, domain knowledge and knowledge patterns in a knowledge discovery process using context mediation. Context fundamentals are introduced, which encompasses the concepts of context identity, sem...

On-line Virtual Museums: An Application of an On-line VR Museum for the Parthenon Marbles

Internet: A Means of Cultural Repatriation

by Kleio Tzanaki

2004

Among the most debated archaeological problems is the repatriation of cultural objects that have been removed from the country of origin and then dispersed in Museums around the world. The need for the return of cultural objects to their homelands is not only derived from the people they belong to, but also from those they appreciate their value and have archaeological interest in them. However, there are a number of problems revolved around most cases, which prohibit the cultural repatriation to be achieved. The case of the Parthenon Marbles is one of the best-known claims for the repatriation of cultural property, as its sculptures, which constitute an integral part of it, have been removed from the temple and are stored in different Museums. Towards the problem of cultural repatriation...

A Machine Translation Approach to Cross Language Text Retrieval

by Maria Gabriela Fernández-Diaz

2005

Cross Language Text Retrieval (CLTR) has been defined as the retrieval of documents in a language different from that of the original query. To make this possible some kind of mechanism has to be applied in order to translate the information contained in the source sentence. Many different approaches have been carried out with the purpose of transferring the information from the source language query to the target language one. Though all these methods deal with a way of translating as much information as possible from the source query, little research has been conducted in relation to the field of Machine Translation (MT). The purpose of this research work is to determine the feasibility of using MT techniques for CLTR. Specifically, I will describe how a MT system has been adapted withou...

The Relationships Between Job Characteristics, Job Satisfaction, and Turnover Intention Among Software Developers

by Dr. Timothy Lee Doré

2005

Software developer turnover can have disastrous effects on an organization due to the loss of business process knowledge, as well as acquired technical skills. Annual rates of turnover in information technology (IT) departments have been estimated at 20% or more with the cost of replacing technology workers ranging from 1.5 to 2.5 times annual salaries. This study purposely focused only on software developers as opposed to IT employees in general due to the critical nature of their work. The factors leading to turnover intention in this field are poorly understood; therefore, this study was designed to further understand the relationships between job characteristics, job satisfaction, and turnover intention among software developers. 326 web surveys were completed that contained questions...

Introduction to Quantum Computation

by Ioan Burda

2005

Introduction to Quantum Computation is an introduction to a new rapidly developing theory of quantum computing. The book is a comprehensive introduction to the main ideas and techniques of quantum computation. It begins with the basics of classical theory of computation: NP-complete problems, Boolean circuits, Finite state machine, Turing machine and the idea of complexity of an algorithm. The general quantum formalism (pure states, qubit, superposition, evolution of quantum system, entanglement, multi-qubit system ...) and complex algorithm examples are also presented. Matlab is a well known in engineer academia as matrix computing environment, which makes it well suited for simulating quantum algorithms. The (Quantum Computer Toolbox) QCT is written entirely in the Matlab and m-files ar...

The Development and Use of an Instrument to Measure Adult Learners’ Perceived Levels of Computer Competence, Attitudes Toward Computers, and Attitudes Toward e-Learning Within a Corporate Environment

by Steven R. Yacovelli

2005

While "e-learning" has proliferated in our society, the problem exists that many corporations are delving into e-learning without fully understanding end users’ self-reported computer competence or attitudes toward e-learning or computers in general, which could ultimately impact the success of e-learning at an organization. Studies have been done to examine these phenomena, but the vast majority center around the academic environment, and many are deemed archaic due to advances in technology. To examine this problem, this research study’s goal was to develop a valid and reliable instrument that measures self-reported computer competence, overall attitudes toward computers, and attitudes toward e-learning appropriate for the corporate, adult learner. The author reviewed various investig...

An Open Design for Computer-Aided Algorithmic Music Composition

athenaCL

by Christopher Ariza

2005

This dissertation introduces a new design for a computer-aided algorithmic music composition system. Rather than exploring specific algorithms, this study focuses on system and component design. The design introduced here is demonstrated through its implementation in athenaCL, a modular, polyphonic, poly-paradigm algorithmic music composition system in a cross-platform interactive command-line environment. The athenaCL system offers an open-source, object-oriented composition tool written in Python. The system can be scripted and embedded, and includes integrated instrument libraries, post-tonal and microtonal pitch modeling tools, multiple-format graphical outputs, and musical output in Csound, MIDI, audio file, XML, and text formats. Software design analysis is framed within a broad his...
