Aggregation Is One Of The Challenges In Learning Probabilistic Relational Models, Saleh M., Jane Jaleel Stephan, Lamia Abed Noor

Iraqi Journal of Computers, Communications, Control and Systems Engineering

Aggregation is a tool used in presenting the multiple instances of an individual attribute in a single value that characterizes the groups represented. However, probabilistic relational models are constructed from relational data base; these data are interrelated with different cardinalities so it is needed for aggregation in some situations in order to convert the relation cardinality from “many” to “one”. This paper will shed light on the role of aggregation in learning probabilistic relational models through presenting two aggregate functions one is conventional and the other is proposed and compare their effects on the produced models. The results produced from …

Improving Hiding Information Process Based On Ga Technique With Secure Extraction Process, Lina Saeed, Susan S. Ghazoul

Iraqi Journal of Computers, Communications, Control and Systems Engineering

In this paper we propose a new method of hiding information that produces a stego-image which is totally indistinguishable from the original image to extract the hiding message. GA is used as an efficient method to minimize the number of different bits between the cover image and the stego-image as minimum as possible by embedding the message in random locations of cover image, and then modifying the locations containing changed information in original image (cover) to improve stego-image quality. To satisfy excellent security we used a crypto-key which contains encrypted locations from hiding process. This key is used to extract …

Quantification Of Uncertainty Associated With Injecting Carbon Dioxide, And Design Of Ecbm Reservoir In Appalachian Basin Coals, Jesma Mohan

Graduate Theses, Dissertations, and Problem Reports (ETD)

There are tremendous coal bed methane resources throughout the world. However, with conventional production methods, 40-80% of methane is left behind as unrecoverable. Enhanced coal bed methane (ECBM) recovery by injection of Carbon dioxide (CO2) is motivated by the dual benefits of improved gas recovery and green house gas storage. In practice, this technology is relatively new, still in the early stage of development, and the economic performance of ECBM has yet to be verified. Due to the complexity of CBM reservoirs, the production performance involves significant uncertainties. It is imperative to quantify the uncertainty of production performance in order …

Design And Development Of A Prototype Of Dual Modality Pet/Optical Breast Cancer Margin Specification Imager, Krishna Nandanavanam

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis is an attempt to develop a prototype of a breast cancer imager to assess the margins of excised breast tissue. This device is proposed to be used to assure that the entire cancerous lesion has been removed by imaging the intensity of a radio labeled tracer and inspecting for a noncancerous margin in the volume of the tissue sample. The dual modality PET/optical breast cancer specification imager uses a pair of small PET detectors to measure the bioactivity of an excised sample of tissue. A co-registered optical image is taken to allow the surgeon to visually correlate the …

Reframing Antitrust In Light Of Scientific Revolution: Accounting For Transaction Costs In Rule Of Reason Analysis, Alan J. Meese

Faculty Publications

This Article contends that modern rule of reason analysis, informed by workable competition’s partial equilibrium trade-off paradigm, is suitable for evaluating only a subset of agreements that may reduce transaction costs. The Article distinguishes between “technological” and “non-technological” transaction costs. Technological transaction costs entail the bargaining and information costs first emphasized by Ronald Coase, while non-technological transaction costs result from more fundamental departures from perfect competition, departures creating a risk of opportunism that accompanies relationship-specific investments. Modern law does accurately assess restraints that may reduce technological transaction costs—costs that are analogous to the sort of production costs recognized by the …

Is Punishment Relevant After All? A Prescription For Informing Juries Of The Consequence Of Conviction, Jeffrey Bellin

Faculty Publications

The American jury, once heralded as “the great corrective of law in its actual administration,” has suffered numerous setbacks in the modern era. As a result, jurors have largely become bystanders in a criminal justice system that relies on increasingly severe punishments to incarcerate tens of thousands of offenders each year. The overwhelming majority of cases are resolved short of trial and, even when trials occur, jurors are instructed to find only the facts necessary for legal guilt. Apart from this narrow task, jurors need not, in the eyes of the law, concern themselves with whether a conviction and subsequent …

The Effect Of Dividing Attention On The Maintenance Of Object Representations, Jillian Christine Mayer

Theses

Numerous theories have been developed in explanation of object perception, such as Feature Integration Theory, which posits that an object is perceived after two stages: a pre-attentive stage and a focused attention stage. It is during the focused attention stage that a representation of the perceived object is formed. Theories such as object file theory account for the maintenance of these object representations following their creation. Evidence for object file theory has been provided by studies of the object specific preview benefit. This thesis seeks to examine the effect that dividing attention has on the maintenance of object representations. Using …

The Influence Of Auditory Cues On Visual Spatial Perception, Joseph W. Geeseman

Theses

Traditional psychophysical studies have been primarily unimodal experiments due to the ease in which a single sense can be isolated in a laboratory setting. This study, however, presents participants with auditory and visual stimuli to better understand the interaction of the two senses in visuospatial perception. Visual stimuli, presented as Gaussian distributed blobs, moved laterally across a computer monitor to a central location and "bounced" back to their starting position. During this passage across the screen, a brief auditory "click" was presented via headphones. Participants were asked to respond to the bounce of the ball, and response latency was recorded. …

The Life Space Interview In Therapeutic Crisis Intervention: An Action Research Study On Its Implementation In A Suburban High School, Susan J. Flood

Education Doctoral

Students with emotional and behavioral disabilities experience less school success than any other subgroup of students. The educational system is the only institution mandated to serve children and youth with emotional disabilities; however, for approximately 51% of these students, the educational experience ends with the decision to drop out of school. For novice teachers, an early experience with a disruptive student can end their career, while even experienced teachers may feel daunted by student behavior. Educators are searching for more effective means of working with students with emotional needs whose unresolved conflicts can escalate into classroom disruption, lack of student …

Photonic Crystal Design And Fabrication Assisted By Tunable Femtosecond Oscillator Laser, Kristofer B. Ohlinger

Theses and Dissertations - UTB/UTPA

Photonic Crystals have the potential for engineered light interaction as directed by the photonic bandgap, a property that details the prohibited propagation region and ultimately the ability to guide light. A so called, photonics-on-chip, would incorporate arbitrary light guiding with functional elements in one package. The realization of such a device is subject to the fabrication paradigms implemented and this thesis is concerned with holographic lithography as a means for creating polymer photonics crystal templates and two-photon polymerization for incorporating light guiding pathways.

In this thesis, the design of the to-be-fabricated structures has been co-opted by computational exploration of the …

The Conservative Conversation, Heather Hall

Theses and Dissertations - UTB/UTPA

The conservative movement is defined by its ideology as well as its rhetoric. Richard Weaver’s conversion to the Right offers an opportunity to define conservatism and conservative rhetoric through his hierarchy of argumentation, and his examination of Plato’s Phaedrus allows an examination of the speaker’s nature and the nature of rhetoric. Glenn Beck, one of today’s most controversial conservative representatives, also deserves examination for his ideology and rhetoric. Both Richard Weaver and Glenn Beck bear scrutiny as influential members of the conservative movement and the role their rhetoric has in the conservative conversation today.

Predicting College Student Classroom Performance With A Simple Metacomprehension Scale, Amber Lee Klein

Theses and Dissertations - UTB/UTPA

The present study investigated the relationship between college student metacomprehension and the error of predicted classroom performance. College student metacomprehension was evaluated using the Metacomprehension Scale (MCS) designed by Moore, Zabrucky, and Commander (1997a). Prior to an examination administered by a course instructor, covering course content, students predicted the percentage score he/she expected to achieve. The predicted score was subtracted from the obtained score generating an error score. It was hypothesized that error of predicted classroom performance is a function of student metacomprehension, as measured by the MCS. Results indicate the MCS was not a reliable indicator of student predicted …

Provide Visual Structure For Students With Asd, Tina Taylor

Faculty Publications

World renowned animal scientist and autism self-advocate Temple Grandin said, "People on the autism/Asperger spectrum have uneven skills. They are often good at one type of learning and bad at another. Educators need to work on building up the area of strength." She explains that three cognitive areas of strength are those who are visual thinkers, pattern thinkers, and word thinkers. Visual thinkers are more inclined to think in pictures rather than words. They may excel in graphic design, industrial design, animation, geometry, or trigonometry. Pattern thinkers have abstract visual thoughts where they can see patterns and relationships between numbers. …

Multi-Threshold Cmos Circuit Design Methodology From 2d To 3d, Ross Josiah Thian

Graduate Theses and Dissertations

A new and exciting approach in digital IC design in order to accommodate the Moore's law is 3D chip stacking. Chip stacking offers more transistors per chip, reduced wire lengths, and increased memory access bandwidths. This thesis demonstrates that traditional 2D design flow can be adapted for 3D chip stacking. 3D chip stacking has a serious drawback: heat generation. Die-on-die architecture reduces exposed surface area for heat dissipation. In order to reduce heat generation, a low power technique named Multi-Threshold CMOS (MTCMOS) was incorporated in this work. MTCMOS required designing a power management unit (to control when and which gates …

A Methodology For Implementing Rf Bists In Production Testing To Replace Rf Conventional Tests, Deepa Mannath

Time Cost Evaluation For Executing Rfid Authentication Protocols, Kevin Chiew, Yingjiu Li, Tieyan Li, Robert H. Deng, Manfred Aigner

Research Collection School Of Computing and Information Systems

There are various reader/tag authentication protocols proposed for the security of RFID systems. Such a protocol normally contains several rounds of conversations between a tag and a reader and involves cryptographic operations at both reader and tag sides. Currently there is a lack of benchmarks that provide a fair comparison platform for (a) the time cost of cryptographic operations at the tag side and (b) the time cost of data exchange between a reader and a tag, making it impossible to evaluate the total time cost for executing a protocol. Based on our experiments implemented on IAIK UHF tag emulators …
