Logic Functions From Three-Terminal Quantum Resistor Networks For Electron Wave Computing, Cheng-Hsiao Wu, Diwakar Ramamurthy Jan 2002

Logic Functions From Three-Terminal Quantum Resistor Networks For Electron Wave Computing, Cheng-Hsiao Wu, Diwakar Ramamurthy

Electrical and Computer Engineering Faculty Research & Creative Works

Electron transmission characteristics through a generalized three-terminal clean Aharonov-Bohm ring is investigated with an arbitrary terminal configuration. This three-terminal ring is shown to be the most basic quantum resistor network that is suitable for electron wave computing, as we demonstrate in this work. There are four basic classes of three-terminal rings. The scaling relation in each class is deduced. Thus the transmission characteristics in each class are valid from an atomic-scale-sized ring to a mesoscopic-scale-sized one, limited only by the electron phase-breaking length. The Buttiker symmetry rule is essential when searching for basic logic functions. Logic functions such as IF-THEN, …

You Are Likely To Be Eaten By A Grue: How Computer Games Are Consuming Modern Culture, Douglas Alexander Jan 2002

You Are Likely To Be Eaten By A Grue: How Computer Games Are Consuming Modern Culture, Douglas Alexander

Theses

Computer games represent an area of untapped, unappreciated potential in the human-computer relationship. Having long been considered "low culture" and unworthy of scholarly attention, the focus on games is intensifying as the field of ludology emerges. The first game was created forty years ago, and since then games have branched out from their traditionally young male user base and gained popularity with both adults and females. Violence in and addiction to games remain controversial topics, but the threat posed by games fades a bit in comparison to the fascinating insights they give us into literature, art, and cinema. Their cultural …

Aspects Of Cognition In Human Mate Selection, Michael J. Stasio Jan 2002

Aspects Of Cognition In Human Mate Selection, Michael J. Stasio

LSU Doctoral Dissertations

Evolutionary perspectives on human mating have provided testable hypotheses regarding what qualities people desire in their mates and why they want them. One study was conducted to replicate previous findings in mate preference using a more sophisticated paired comparison methodology to develop scales. Paired comparison scaling generally replicated gender differences in mate preferences consistent with evolutionary predictions. Further, decision-making reaction time (ms) suggested the presence of an underlying psychological continuum of selection criteria. A series of studies were then conducted applying the information processing approach (IPA) to investigate attention and knowledge organization in mate preference. The dot-probe paradigm was used …

A Quantitative Similarity Metric For Design-By-Analogy, Daniel A. Mcadams, Kristin L. Wood Jan 2002

A Quantitative Similarity Metric For Design-By-Analogy, Daniel A. Mcadams, Kristin L. Wood

Mechanical and Aerospace Engineering Faculty Research & Creative Works

During the design and development of new products, design engineers use many techniques to generate and define new and "good" concepts. Inherent in this search for solutions is the conscious and unconscious reliance on prior experience and knowledge, or design-by-analogy. In this paper, a quantitative metric for design-by-analogy is developed. This metric is based on the functional similarity of products. By using this product-similarity metric, designers are able to formalize and quantify design-by-analogy techniques during concept and layout design. The methods, as developed in this paper, allow a designer with limited experience to develop sophisticated solutions that enhance the overall …

Band Selection And Algorithm Development For Remote Sensing Of Wildfires, Andrew Fordham Jan 2002

Band Selection And Algorithm Development For Remote Sensing Of Wildfires, Andrew Fordham

Theses

The environmental damage and global change caused by wildfires are fast becoming issues of local, regional and global concern. Remote sensing techniques are an ideal tool to use for monitoring these threats. Unfortunately, most existing satellites were built for other purposes and are less than ideal for the problems associated with detecting, assessing and monitoring fires. This thesis examines the phenomenology of fires and rank orders several non-traditional detection strategies that have the promise of being more cost effective and less susceptible to false alarms than existing satellite systems and algorithms. The possibility of detecting fires with multi-band "color" measurements …

Elastic Ladar Modeling For Synthetic Imaging Applications, Robin Burton Jan 2002

Elastic Ladar Modeling For Synthetic Imaging Applications, Robin Burton

Theses

The Digital Imaging and Remote Sensing Image Generation (DIRSIG) model was developed to create synthetic images of remotely sensed scenes (Schott et al. 1999). It is a quantitative model based on first principles that calculates the radiance reaching the sensor from the visible region of the spectrum through to the long-wave. DIRSIG generates a very accurate representation of what a sensor would see by modeling all processes involved in the imaging chain. Currently, DIRSIG only models light from passive sources such as the sun, blackbody radiation due to the temperature of an object, and local incoherent illuminants. Active systems allow …

End To End Congestion Control In High-Speed Networks, Sarangapani Jagannathan Jan 2002

End To End Congestion Control In High-Speed Networks, Sarangapani Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

This paper proposes an adaptive methodology to prevent congestion in packet switched networks such as the Internet, where the internal network nodes convey very little information to the ingress nodes. Two architectures of preventing the congestion are presented: the first one when the traffic arrival rates, and bottleneck queue levels are known and the other when these are unknown. In the latter, the network traffic is estimated online using an adaptive system by measuring the buffer occupancy. In both architectures, the congestion is controlled by adjusting the transmission rates of non real-time and certain real-time sources in response to the …

Distributed Power Control In Wireless Communication Systems, Sarangapani Jagannathan, A. T. Chronopoulos, S. Ponipireddy

Electrical and Computer Engineering Faculty Research & Creative Works

Energy efficiency is a measure of performance in wireless networks. Therefore, controlling the transmitter power at a given node increases not only battery operating life, but also overall system capacity by successfully admitting new links. It is essential to find effective means of power control in point-to-point, broadcasting and multicasting scenarios. Wireless networking presents formidable challenges, and we consider the problem of unicast or point-to-point (peer-to-peer) communication in wireless networks in the presence of other nodes. We study the feasibility of admitting new links in an wireless network operating area while maintaining quality of service (QoS), in terms of signal-to-interference …
