Communication Protocol For Wireless Sensor Networks, Edgar Herbert Jr Callaway Jan 2002

Communication Protocol For Wireless Sensor Networks, Edgar Herbert Jr Callaway

Electronic Theses and Dissertations 2000 - 2009

Many wireless network applications, such as wireless computing on local area networks, employ data throughput as a primary performance metric. The data throughput on such networks has therefore been increasing in recent years. However, there are other potential wireless network applications, such as industrial monitoring and control, consumer home automation, and military remote sensing, that have relaxed throughput requirements, often measured in bits/day. Such networks have power consumption and cost as primary performance metrics, rather than data throughput, and have been called wireless sensor networks. This work describes a physical layer, a data link layer, and a network layer design …

Comparative Study Of Attribute Selection Techniques For Cbr-Based Software Quality Classification Models, Laurent Quoc Viet Nguyen

Electronic Theses and Dissertations 2000 - 2009

To achieve high reliability in software-based systems, software metrics-based quality classification models have been explored in the literature. However, the collection of software metrics may be a hard and long process, and some metrics may not be helpful or may be harmful to the classification models, deteriorating the models' accuracies. Hence, methodologies have been developed to select the most significant metrics in order to build accurate and efficient classification models. Case-Based Reasoning is the classification technique used in this thesis. Since it does not provide any metric selection mechanisms, some metric selection techniques were studied. In the context of CBR, …

Design And Construction Of A High-Sensitivity Capacitance-Based Quartz Dilatometer, George Emerson Timmins Jan 2002

Design And Construction Of A High-Sensitivity Capacitance-Based Quartz Dilatometer, George Emerson Timmins

Electronic Theses and Dissertations 2000 - 2009

A high sensitivity capacitance dilatometer constructed solely of fused quartz was designed to study phase transitions of sub-millimeter sized samples from 4 to 300 K. The minimal thermal expansion contribution from quartz reduced the overall magnitude of the background by a factor of 10. As a consequence, the increased resolution of the data provided greater sensitivity than has been capable with metallic capacitance dilatometers. A one millimeter long single crystal of La1.67Sr0.33NiO 4 was analyzed from 80 to 300 K. Our highly reproducible measurements reveal phase transitions at similar temperatures to those observed with magnetization and specific heat measurement techniques.

Energy-Efficient Protocols For Wireless Sensor Networks, Kemei. Du Jan 2002

Energy-Efficient Protocols For Wireless Sensor Networks, Kemei. Du

Electronic Theses and Dissertations 2000 - 2009

This thesis describes energy-conserving techniques in wireless sensor networks. In wireless sensor networks the sensor nodes gather information and send the information to a base station periodically. Some important messages need be broadcast to all nodes. Due to the limited battery capacity in sensor nodes, energy efficiency is becoming a major challenging problem in these power-constrained networks. Chain-based protocols construct a transmission chain connecting all nodes to save energy dissipation of data transmission. We propose a multiple-chain scheme for all-to-all broadcasting. Furthermore, we develop an energy-efficient chain-construction algorithm which uses a sequence of insertions to minimize the energy consumption along …

Building The Beaver And Lake Erie Canal: The Politics Of Public Improvements In Pennsylvania, 1783-1845., William David Mccarthy

Graduate Theses, Dissertations, and Problem Reports (ETD)

Patterns of commerce and settlement in colonial America were shaped by watercourses and portages. Road building skills were primitive and boating represented the most effective means of moving bulk freight and passengers. Traders and frontiersmen leading the advance of European settlement into the Appalachian Mountains therefore adopted the shortest crossings between watersheds. Natural conditions in Pennsylvania did not promote an orderly advance westward and produced isolated clusters of settlement around Philadelphia and Pittsburgh, with small and widespread settlements in Northwest Pennsylvania. State leaders were hard pressed to define the limits of Pennsylvania until the end of the eighteenth century, and …

Development Of Mechanistic-Empirical Damage Assessment Procedures For Crc Pavements With Emphasis On Traffic Loading Characteristics., Olga I. Selezneva

Graduate Theses, Dissertations, and Problem Reports (ETD)

Edge punchout has been long recognized as the prevailing mode of structural failure in Continuously Reinforced Concrete Pavements (CRCP) and yet, has remained relatively unexplored and unexplained. The existing design and evaluation procedures for CRCP employ American Association of State Highway Transportation Officials (AASHTO) equations for the jointed concrete pavements and the Equivalent Single Axle Load (ESAL) approach that will neither predict nor address edge punchouts. A comprehensive procedure for prediction of CRCP structural deterioration based on fundamental mechanical principles was developed in this study. This procedure directly considers the key design factors and site conditions affecting formation of edge …

Technologies Of A "New World" Citizenship: American Frontier Narratives In The Late-Twentieth Century., Catherine Courtney Gouge

Graduate Theses, Dissertations, and Problem Reports (ETD)

Many contemporary American narratives about frontiers emphasize the displacement of the American Dream of infinite resources to a space that is always just beyond our reach and underscore the effect of the frontier as a means for Americans to organize a psychic identity, an identity that achieves stability and coherence through images of exploring and colonizing the frontier. Such texts invoke images of power and control to suggest that to be American we must find and pursue frontiers. Each of the late-twentieth century American narratives I look at in this project testifies to the enduring power of the concept of …
