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 …

Photometric Stability And Subpixel Sensitivity Of A Back-Illuminated Ccd, Albert Piterman Jan 2002

Photometric Stability And Subpixel Sensitivity Of A Back-Illuminated Ccd, Albert Piterman

Theses

Characterization of scientific-grade CCDs is extremely important if one hopes to attain very precise quantitative results. A number of characterization methods exist that yield accurate and fast properties in order to make simple measurements. As CCDs are pushed to the their operating limit, other, esoteric tests are required. In this situation, such tests become the determining factors for usability of CCDs. The research presented in this dissertation describes two such tests. This work first examines the ultimate signal-to-noise achievable with a back-illuminated CCD. The focus of this research is on the ability of the tested sensor to reach and continuously …

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 Jan 2002

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 …

A Hybrid System Theoretic Approach For Admission Controller Design In Multimedia Networks, Sarangapani Jagannathan Jan 2002

A Hybrid System Theoretic Approach For Admission Controller Design In Multimedia Networks, Sarangapani Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

A novel real-time discrete-event admission control (AC) scheme for high-speed networks is proposed with the aim of attaining a desired quality of service (QoS) and high network utilization. The AC uses the available capacity from a novel adaptive bandwidth estimation scheme, a congestion indicator derived from a congestion controller, peak bit/cell rate (PBR/PCR) estimate from new sources, along with the desired QoS metrics, and makes decisions whether to 'admit' or 'reject' new sources. The novel aspect of the proposed approach is the application of hybrid system theory to prove the performance of the admission controller, stability and the development of …

Deep Structures Wet Etched Into Lithium Niobate Using A Physical Mask, Andrew Randles Jan 2002

Deep Structures Wet Etched Into Lithium Niobate Using A Physical Mask, Andrew Randles

Theses

The present work is an investigation and characterization of a new technique for etching and masking Lithium niobate (LiNb03) to realize high aspect ratio trenches. LiNb03 is a single crystal optically clear (from 350 nm to 5 micometer wavelength), piezoelectric material. It is also inert to most reactants and has a high curie temperature (the temperature that a material loses its piezoelectric effect). These properties allow LiNb03 to be used as a sensor or actuator in harsh environments. To realize this actuator/sensor a multilevel lithium niobate deep etching technique is currently unavailable. The present work uses a chrome gold mask …

Experimental Evaluation Of Impulse Turbine Designs For Chain Testing Systems, Aaron Donlon Jan 2002

Experimental Evaluation Of Impulse Turbine Designs For Chain Testing Systems, Aaron Donlon

Theses

There are several ways to test automotive timing chains for wear in a laboratory environment. One novel method proposed by Borg-Warner Morse TEC uses fluid jets striking an impeller blade. The momentum of the oil striking and deflected by the impeller blade is used to produce a torque. This torque is transmitted to the system through the timing chain. A previous theoretical design study (conducted elsewhere) evaluated some of the design factors as they related to machine performance and ultimately to the torque loads applied to the chain.
