Hellfire And Damnation Through Crime Or Bliss Through Faith: A Look At Faith-Based Corrections, Gregory Paul Warren Wuthrich
Hellfire And Damnation Through Crime Or Bliss Through Faith: A Look At Faith-Based Corrections, Gregory Paul Warren Wuthrich
UNLV Retrospective Theses & Dissertations
The latest movement in trying to combat the U.S. crime problem is through "faith-based" corrections. These programs are in the infancy stages and minimal data are present at this time to illustrate true effectiveness of such programs. This study is a theoretical evaluation of such programs and incorporates a framework from Gary LaFree (1988). Results indicate that "faith-based" programs tend to be one dimensional and in order for them to work properly they must be set up in conjunction with other institutional changes. Often other theories can incorporate the dimension of religion, yet religion alone, such as through "faith-based" programs, …
A Label Based Routing Protocol For Wireless Sensor Networks, Naoto Kimura
A Label Based Routing Protocol For Wireless Sensor Networks, Naoto Kimura
UNLV Retrospective Theses & Dissertations
One of the challenging issues in wireless sensor networks is to acquire, process, and transmit information using the least amount of battery power; In response to this problem, a novel routing scheme for wireless sensor networks, called "Information Dissemination via Label Forwarding (IDLF)", is presented. IDLF consists of three information exchanging stages. In the first stage, a label is disseminated by a source. After a sink receives the label, it replies a request to the source. By exchanging a label and request, a data path between a source and sink is formed. Finally, an actual data is transmitted through the …
Design And Implementation Of A Fast Fourier Transform Architecture Using Twiddle Factor Based Decomposition Algorithm, Bhaarath Kumar
Design And Implementation Of A Fast Fourier Transform Architecture Using Twiddle Factor Based Decomposition Algorithm, Bhaarath Kumar
UNLV Retrospective Theses & Dissertations
With the advent of signal processing and wireless communication mobile platform devices, the necessity for data transformation from one form to another becomes an unavoidable aspect. One such mathematical tool that is widely used for transforming time and frequency domain signals is Fourier Transform. Fast Fourier Transform (FFT) is perhaps the fastest way to achieve transformation. Many algorithms and architectures have been designed over the years in an attempt to make FFT algorithms more efficient and to target many applications; The main objective of our work is to design, simulate and implement an architecture based on the Twiddle-Factor-Based decomposition FFT …
Non-Lithographic Fabrication Of Nickel Based Antidot System For Potential Gmr Device Applications, Saurabh Amitabha Mookerjea
Non-Lithographic Fabrication Of Nickel Based Antidot System For Potential Gmr Device Applications, Saurabh Amitabha Mookerjea
UNLV Retrospective Theses & Dissertations
The antidot system is an interesting material for applications in GMR (Giant Magnetoresistance) device technology. Such devices have been the subject of investigation for its physics during the past fifteen years; however there has not been any focus towards application in GMR technology. The objective of this thesis is to develop a optimum device configuration as well as process technology for GMR applications of antidot structures. This thesis describes two different non-lithographic techniques for the fabrication of nickel based antidot systems. The first technique uses an alumina template as a mask to etch holes on the underneath nickel. Preliminary data …
A Gis Based Tool To Determine Optimal Routes, Rajeev Naroor
A Gis Based Tool To Determine Optimal Routes, Rajeev Naroor
UNLV Retrospective Theses & Dissertations
Travel in urban and suburban areas is an important activity in an individual's daily time budget. Each trip is preceded by a planning process for selecting a "desirable" or an optimal route from the origin to destination. "Optimal" can take many forms, such as shortest time, shortest distance, least total cost, or safest/most reliable path. Reliable paths are of interest because of the impacts of congestion on travel tomes, and the resultant variability in travel times. A model to help identify optimal travel paths based on travel time variability is developed in this research; Congestion on streets is one of …

Study On Immobilizing Radionuclides In Apatite-Based Host Phase Materials, Gunanda Weduge Chinthaka Silva
UNLV Retrospective Theses & Dissertations
Fluorapatite is well known for its properties such as high thermal stability, chemical durability and its resistibility to radiation damage. These properties have been taken into account when it was considered as waste form material for fluoride salts like Cs, Sr and rare earths. The research as described in this thesis was carried out in order to determine the feasibility of incorporating other elements into fluorapatite as surrogate for nuclear waste without affecting any of its properties, especially the thermal stability. The aim was to accomplish incorporations in a way so that some of the calcium ions in the fluorapatite …
Design Of Fuzzy Logic Based Adaptive Traffic Signal Controller, Murali Mohan Ande
Design Of Fuzzy Logic Based Adaptive Traffic Signal Controller, Murali Mohan Ande
UNLV Retrospective Theses & Dissertations
Traffic control of street intersections is one of the most critical elements in providing an efficient flow of traffic in urban networks. Conventionally, pretimed controllers are used, but they cannot respond to real time fluctuations in traffic demand. Traffic actuated signals provide an improvement over pretimed controllers, but their performance deteriorates under heavy traffic conditions. These conditions necessitate the development of a controller that responds to actual traffic demand in real time, with the objective of minimizing vehicle delays, number of stops, etc. Fuzzy logic provides the potential for development of a system that would address these needs; The objective …

The purpose of this study is to identify critical factors for successful Six-Sigma implementation by using the Analytical Hierarchy Process (AHP) approach. Twenty-one experts, consisting of three-project champions and eighteen-black belts from five multinational companies (Singapore, Japan, and USA) locating in Thailand, were interviewed. The study has gone through four phases, including: (1) determining critical factors and performance measures in Six-Sigma implementation; (2) structuring the problem and building the AHP model; (3) collecting data from expert interviews; and (4) determining the normalized priority weights of individual factors and sub-factors. Expert Choice software was used to compute the normalized and unique …
Generic Construction Of (Identity-Based) Perfect Concurrent Signatures, Sherman S. M. Chow, Willy Susilo
Generic Construction Of (Identity-Based) Perfect Concurrent Signatures, Sherman S. M. Chow, Willy Susilo
Faculty of Informatics - Papers (Archive)
The notion of concurrent signatures was recently introduced by Chen, Kudla and Paterson. In concurrent signature schemes, two entities can produce two signatures that are not binding, until one of the parties releases an extra piece of information (namely the keystone). Subsequently, it was noted that the concurrent signature scheme proposed in the seminal paper cannot provide perfect ambiguity. Then, the notion of perfect concurrent signatures was introduced. In this paper, we define the notion of identity-based (or ID-based) perfect concurrent signature schemes. We provide the first generic construction of (ID-based) perfect concurrent signature schemes from ring signature schemes. …

Cancelable Key-Based Fingerprint Templates, Russell Ang, Reihaneh Safavi-Naini, Luke F. Mcaven
Faculty of Informatics - Papers (Archive)
Biometric based authentication can provide strong security guarantee about the identity of users. Security of biometric data is particularly important as compromise of the data will be permanent. Cancelable biometrics store a non-invertible transformed version of the biometric data and so if the storage is compromised the biometric data remains safe. Cancelable biometrics also provide a higher level of privacy by allowing many templates for the same biometric data and hence non-linkability of user's data stored in different databases. We define how to measure the success of a particular transformation and matching algorithm for fingerprints. We consider a key-dependent geometric …

This paper proposes a model-based adaptive control methodology for piezoelectric actuation systems to follow specified motion trajectories. This is motivated by a search for an effective control strategy to deal with the problem of parametric uncertainties such as disturbance and hysteresis effects. The proposed adaptive law is formulated by combining a parameter compensator and a conventional PD feedback control for a system to drive its position tracking error converging to zero. The fundamental concept lies in the properties of a quasinatural potential function, which allows a saturated position error function in the control formulation. Implementation of the control law requires …

Embedding capacity, distortion and resilience to attacks are three key indicators to the performance of any image watermarking systems. Study has shown that Quantization Index Modulation (QIM) can in general achieve higher embedding capacity than Spread Spectrum (SS) systems at the same level of distortion. However, QIM is more sensitive to simple attacks such as Additive White Gaussian Noise (AWGN), Uniform Distribution Noise (UDN), and JPEG compression. This paper proposed a system to decompose the host signal into the embedding signal that is designed to be resilient to attacks and the correction signal. QIM is applied on the embedding signal …

Conveying distinctive and coherent brand associations is a key concern of modem brand management. Brands with a concise, consumer-relevant, and unique brand image are preferred by consumers. This study considers the contribution brand names can provide to building customer based brand equity. Recent cognitive theories of conceptual combination fonn the theoretical basis for analyzing consumer reactions toward brand names. Following these theories, three techniques to integrate brand name and product are developed. Reaction time measurements and association tests show that the techniques presented are an effective and efficient means to convey a brand's image.

Adoption Of The Disclosure-Based Regulation For Investor Protection In The Primary Share Market In Bangladesh: Putting The Cart Before The Horse?, S M. Solaiman
Faculty of Law - Papers (Archive)
The Bangladesh securities market, despite ifs operation of half of a century, remains in embryonic form. The market has been suffering from a chronic lack of investor confidence since 1997 following an unprecedented share scam. Ever since, the government has been striving in vain to promote investment by progressively offering incentives to investors and corporations. The government watchdog unexpectedly introduced the Disclosure-Based Regulation (DBR) in January 1999 to protect investors from the misfeasance of other players in the market for Initial Public Offerings. Recent studies have identified some problems in the market, which are unfavourable for the new regime. In …

Barriers In The Adoption Of A Market Orientation By Locally Based Non-Profit Organisations (Npos), Gary I. Noble
Barriers In The Adoption Of A Market Orientation By Locally Based Non-Profit Organisations (Npos), Gary I. Noble
Faculty of Commerce - Papers (Archive)
The need for non-profit organisations (NPOs) to adopt a ‘market orientation’ has been promoted widely in the academic literature. To date, research in this area has focussed on either measuring the degree of market orientation within an NPO or detailing the financial and other benefits that accrue from a market orientation. Although this body of research acknowledges there are barriers to the adoption of a market orientation no study has identified the nature of these barriers. This study contributes to our knowledge by identifying what managers of small locally based NPOs perceive as the main barriers to the adoption of …
Evaluation Of Concept Lattices In A Web-Based Mail Browser, Shaun Domingo, Peter W. Eklund
Evaluation Of Concept Lattices In A Web-Based Mail Browser, Shaun Domingo, Peter W. Eklund
Faculty of Commerce - Papers (Archive)
Concept lattices assist human understanding in three ways: firstly, by collecting formal concepts that contain maximal sets of objects with shared attributes; secondly, the relatedness of concepts is revealed by providing a hierarchy of formal concepts in the information space. Finally, the concept lattice (drawn as a line diagram) reveals inferences that can automatically derive association rules. Therefore, a major hypothesis of the application of concept lattices is that they visually assist in understanding the structure of information contained within an information space. However, there has been little in the way of empirical tests to substantiate this hypothesis. This paper …

Articulating Knowledge Work: The Contributions Of Activity Theory And Task-Based Knowledge Management, Henry Linger, Frada Burstein, Helen M. Hasan
Faculty of Commerce - Papers (Archive)
This chapter addresses issues of knowledge work in organisations with a concern that mainstream knowledge management (KM) has fallen short of expectations. The real nature of knowledge work remains hidden, and thus inaccessible, to those who are trying to improve organisational outcomes through KM practices. The authors have conducted independent research within a new discourse on knowledge work in the context of modem complex organisations, the results of which are converging to a common understanding of this critical phenomenon. Their two theoretical frameworks, one task-based and one activity-based, are described here as eminently suited to this research. Two sets of …

The impact of many well intentioned technology integration projects has not always been viewed favourably. In fact, many projects are destined to fail from the outset by not considering fundamental IT system inves tment risks (technical failure, data failure, user failure, organizational failure) [Lyytinen & Hirschiem, 1987]. With any new technology ‘an element of uncertainty exists in the minds of decision makers with respect to the successful adoption of them’ [Bagozzi et al, 1992]. Uncertainty towards adopting new technologies is not solely the domain of decision makers. Apart from chief technology and information officers, system administrators and help desk personnel, …

The chitosan/polyaniline (PANi) semi-interpenetrating network polymers (semi-IPN)s were prepared under different pH conditions. Changes of structural properties were investigated using Fourier transform infrared (FT-IR) spectroscopy, Solid-state 13C NMR and wide angle X-ray diffraction (WAXD). The spectroscopic studies revealed that the PANi had converted to its pH-switched, emeraldine salt (ES) form when prepared from solutions of pH

Polythiophene, one of the most extensively studied conducting polymers, was selected as an actuator material due to its chemical and electrochemical stability both in air and moisture. In this work, poly(3-methylthiophene) based actuators were constructed electrochemically with a tubular geometrical configuration. The actuation behaviour was investigated regarding to the actuation strain generated, the stress produced and work per cycle performed by poly(3-methylthiophene) actuators. The effect of potential sweep rate and different electrolytes (ionic liquid and organic solvent) on the actuation performance were also explored. Poly(3-methylthiophene) actuators show an increase in actuation strain with an increase in applied load.

This paper presents theoretical and experimental investigation of mechanical-electrical properties of conducting polymers based bimorph sensors. A material parameter, hCP , is proposed to represent linear relationship between induction charge and the applied external deformation. Based on this assumption, a constitutive equation for bimorph sensors under steady-state external loadings are constructed and then solved. Mechanical-electrical properties of bimorph sensors are experimentally studied using both vibration-amplitude sweep mode and frequency sweep mode. The material parameter hCP , is identified by comparing theoretical analysis and experimental results. The applications of conducting polymers based bimorph sensors in smart structures are also …

The high-temperature creep-deformation behavior of a Ni-based M963 superalloy has been investigated over a broad stress range of 80 to 600 MPa at high temperatures (800 °C to 975 °C). The detailed dislocation configurations at different creep stages are examined through transmission electron microscopy (TEM). The results show that the deformation mechanism is stress and temperature dependent and mainly consists of three dislocation-controlling mechanisms: stacking faults and dislocation-pair shearing, dislocation bowing and Orowan looping, and dislocation climb.

The Conceptual Interface Between Secondary And University Mathematics: A Schema-Based Analysis, Mohan Chinnappan
Faculty of Education - Papers (Archive)
In this paper I provide a theoretical analysis of difficulties experienced by students in having to transfer concepts they have learnt in high school to university mathematics. This analysis is based on the assumption that mathematical knowledge can be represented in the form of organised structures called schemas. The organisational quality of students’ mathematical schemas is a function of spread of network and strength of links between pieces of information. Well-developed schemas are argued here to facilitate assimilation of university mathematical concepts and the use of this new information in the solution of novel problems.
