Organically Deposited Metallic Films For Device Fabrication, Thomas J. O'Keefe, M. Stroder, Matthew O'Keefe

Materials Science and Engineering Faculty Research & Creative Works

Advances in integrated circuit density, speed and complexity are dependent on lower resistance, finer line width on-chip interconnections. Methods for incorporating copper interconnects into IC fabrication processes have been developed which accomplish this objective but most of these methods use some form of blanket metal deposition that requires mechanical and/or chemical removal of excess material. To date, investigations into the selective deposition of conductor materials for device fabrication have met with limited success. A new process for selectively depositing metallic conductors using inexpensive, organic-based chemical solutions could potentially force a paradigm shift in the deposition of metals for microelectronic applications. …

A Transaction Model For Mobile Computing, Sanjay Kumar Madria, Bharat Bhargava

Computer Science Faculty Research & Creative Works

We introduce a prewrite operation before a write operation in a mobile transaction to improve data availability. A prewrite operation does not update the state of a data object but only makes visible the value that the data object will have after the commit of the transaction. Once the transaction has read all the values and declares all the prewrites, it can precommit at a mobile host. The remaining transaction's execution is shifted to the stationary host. Writes on a database consume both time and resources at the stationary host and are therefore delayed. A pre-committed transaction's prewrite values are …

Optical Digital Fragmentation Measuring Systems -- Inherent Sources Of Error, Norbert H. Maerz, Wei Zhou

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Automated optical imaging systems of measuring fragmentation are increasingly being used in the mining, comminution, and materials handling industries. These methods have been well received in many of the industries involved. Considering that in many of these applications there are no alternative ways of sizing material, having even a rudimentary measurement of size distributions allows evaluations of explosive, blast design, detonator performance, crusher and milling performance, and material degradation due to transport.

Optical methods have inherent limitations, which reflect on accuracy, precision, and reproducibility of measurement results. This stems from the fact that there are myriads of variables, which affect …

An Interlibrary Loan System On The World Wide Web, Schubert Shou Boon Foo, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Inter-Library Loan (ILL) service is one of the services provided by libraries that offers users a way to access library resources beyond their affiliated libraries. Additionally, it allows participating libraries to share and maximize their resources. This work examines the ILL process used by libraries in Singapore and proposes that the existing paper-based manual system be replaced by a Web-based ILL system. Such a Web-based system has been successfully designed and implemented at the Nanyang Technological University. The paper presents an overview of the system requirements and architecture, implementation details and demonstrates the feasibility and advantages of the new system.

Child Sexual Abuse In Ireland: An Historical And Anthropological Note, Kevin Lalor

Articles

Child sexual abuse in Ireland has entered the public domain only in the last twenty years. This process was accelerated by a number of high profile cases which became public in the mid 1990s. Prior to the recent past, few references to child sexual abuse in Ireland exist. The first written evidence is found in the Penitentials of the early Christian period. Penance is specified for those that “misuse” children. Mention of adult child sexual relations is also found in the Brehon law texts. Historians, sociologists and anthropologists of childhood suggest that patterns of child rearing vary across time and …

The Changing Nature Of Theory And Practice In Marketing: On The Value Of Synchrony, Aidan O'Driscoll, John Murray

Articles

Any academic discipline with a closely associated area of professional endeavour is profoundly affected by the relationship between its theory and practice. Synchrony in theory and practice adds value to the management of enterprise and to the advance of the discipline. Mindful of this assertion, this article explores the changing nature of theory and practice in marketing. It examines current trends in marketing practice which are occurring as a result of change in markets, technology and organisations. It assesses the state of theory in six subfields of marketing. It also considers developments in closely related management disciplines as well as …

Computer Science Faculty Research & Creative Works

Everyone is talking about Java. The driving force for this chatter is Java''s simplicity and potential power. Java is programming language, and a language for the intranet and the World Wide Web (WWW). Java is a Write On one platform and Run on Many platforms (WORM) language. For network-friendly, platform-independent applications, Java (originally Oak) is an object oriented programming language. Java source code is compiled into a virtual machine code or bytecode. This makes the Java platform independent. It can be placed on a Web site, and executed on the client side on a PC-Intel, Mac, Motorola or UNIX-Solaris machine …

Dc Link Stabilized Field Oriented Control Of Electric Propulsion Systems, Keith Corzine, S. D. Sudhoff, Steven F. Glover, H. J. Hegner, H. N. Robey

Electrical and Computer Engineering Faculty Research & Creative Works

Induction motor based electric propulsion systems can be used in a wide variety of applications including locomotives, hybrid electric vehicles, and ships. Field oriented control of these drives is attractive since it allows the torque to be tightly and nearly instantaneously controlled. However, such systems can be prone to negative impedance instability of the DC link. This paper examines this type of instability and sets forth a readily implemented albeit nonlinear control strategy to mitigate this potential problem.

Rose Ausländer (1901-1988): Austria-Hungary/Germany, Kathrin M. Bower

Languages, Literatures, and Cultures Faculty Publications

Rose Ausländer was born Rosalie Beatrice Scherzer on 11 May 1901 into a German-speaking Jewish family. She spent her childhood in Czernowitz, the capital of Bukovina, a province of the Austro-Hungarian Empire. After World War I, Bukovina was incorporated into Romania, and at the end of World War II was annexed by the Soviet Union. Rosalie Scherzer studied literature and philosophy at the university in Czernowitz but never completed a degree, largely because of the family's poverty after her father's death in 1920. To help alleviate this economic situation, she emigrated to the United States in 1921 with lgnaz Ausländer. …

Contribution Of Externally Bonded Frp To Shear Capacity Of Rc Flexural Members, Ahmed Khalifa, William J. Gold, Antonio Nanni, M. I. Abdel Aziz

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Fiber reinforced polymer (FRP) materials are continuing to show great promise for use in strengthening reinforced concrete structures. These materials are an excellent option for use as external reinforcing because of their light weight, resistance to corrosion, and high strength. Externally bonded FRP sheets have been used to increase moment capacity of flexural members and to improve confinement in compression members. Investigations into the use of externally bonded FRP sheets for shear strengthening have also been conducted and have been shown to be viable. The objectives of this study were to review the current research on shear strengthening with FRP …

Optimizing Multiagent, Multi-Injected Swell Modifier, Marshall B. Addison, Thomas M. Petry

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Interactions of expansive clay soils with transportation facilities have caused billions of dollars of damage. In the process of determining agents and methodologies to overcome expansive clay behavior, multiple injections of chemical agents into the subgrade to modify clay behavior are most promising. A study was conducted to optimize a potassium-rich solution of four parts. The modifying solution has been injected into expansive clay subgrades with success since the early 1970s. A laboratory methodology was developed to inject specimens multiple times and to conduct swell tests. Screening tests were conducted to evaluate linear effects that each of the four constituents …

Hybrid Control Of Seismic Structures With Optimal Placement Of Control Devices, Franklin Y. Cheng, Hongping Jiang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

A theoretical study is carried out for optimal controller placement and effectiveness of a hybrid seismic response control system comprising a viscous fluid damper and a servovalve-controlled hydraulic actuator. A stochastic seismic response of controlled structures is first investigated with nonorthogonal damping and stiffness; then a statistical method for optimal placement of control devices on seismic-resistant structures is developed. With such placement, a hybrid system can achieve greater performance in that much less control force is required to reduce structural seismic response to a given level. This study also shows the hybrid system is superior to both active and passive …

Recent Research And Developments In Cold-Formed Steel Framing, Roger A. Laboube, Wei Wen Yu

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Recent research studies at the University of Missouri-Rolla (UMR) have focused on developing a better understanding of the behavior of cold-formed steel members and truss assemblies. This research was initiated by the more widespread use of cold-formed steel in the residential construction market, and the need to provide structurally reliable, as well as highly economical design solutions. Steel trusses are commonly assembled using C-shaped sections and self-drilling screws. Based on UMR findings, appropriate design recommendations have been proposed for the web and chord members of a truss. Also of concern is the introduction of large holes in the webs of …

Characterization Of Generalized Haar Spaces, M. Bartelt, W. Li

Mathematics & Statistics Faculty Publications

We say that a subset G of C₀(T, ℝ^k) is rotation-invariant if [Qg: g ∈ G]=G for any k x k orthogonal matrix Q. Let G be a rotation-invariant finite-dimensional subspace of C₀(T, ℝ^k) on a connected, locally compact, metric space T. We prove that G is a generalized Haar subspace if and only if P_G(ƒ) is strongly unique of order 2 whenever P_G(ƒ) is a singleton.

Gangs, Drugs, And Delinquency, Tina Renea Engstrom

Dissertations and Theses @ UNI

The main objective of this thesis is to study the link between gangs, drug use, and delinquency. Previous literature suggests that social learning and social control theories commonly provide theoretical contexts for explaining deviant behavior. The present research applies the principles of Sutherland's (1949) theory of differential association and Hirschi' s (1969) theory of social control to the delinquent behavior of gang members and their drug involvement. The present study does not attempt to explain why youths become gang members. Rather, this research uses an integration of social learning and social control theories to explain why gang members become involved …

Database Security: Evaluation Of A Multi-Policy Access Control Model, Fei Dong

Dissertations and Theses @ UNI

As an increasing number of organizations become dependent on access to their data stored in the database, the need for adequate security measures is becoming more and more critical. Enforcing data protection means safeguarding data from unauthorized or improper disclosures or modifications. Access control policies should be independent of the mechanisms that will implement the physical control of access: this allows control mechanism to be available for different policies. Although considerable work was done on access control models and related mechanisms for databases (Castano & Fugini, 1994), current access control models and mechanisms are not flexible enough to meet the …

Recycling Economic Development: Observing The Wage And Occupational Structure Of The Plastics Industry, Dawn Marie Dungan

Dissertations and Theses @ UNI

This thesis provides an exploratory analysis of the occupational and wage structures of a predefined set of plastics companies in Iowa. Characteristics of the occupational and wage structures of recycling and nonrecycling based companies in the plastics industry in Iowa were compared to a standard established by the 1992 Iowa Statewide Wage Survey. The theory of the diminishing middle was used as the guiding framework from which to draw assumptions. The plastics industry was defined as all companies in the state of Iowa engaging in any combination of collection, processing, or manufacturing of recycled or raw plastic products for economic …

An Integrated Approach To Determining The Sequence Of Machining Operations For Prismatic Parts With Interacting Features, Alan C. Lin, Shou Yee Lin, Das Diganta, Wen F. Lu

Mechanical and Aerospace Engineering Faculty Research & Creative Works

This paper proposed a framework for integrating artificial intelligence (AI) techniques and mechanistic models in the task of generating process plans for prismatic parts. The main issue of process planning addressed in this paper is the determination of the operation sequence for mechanical parts containing interacting features where machining of one feature might adversely affect the surface quality of other features. The informed graph-search strategy in AI is used to achieve the function of operation sequence planning. The search graph is built by considering alternative machining operations in converting a blank stock into the final part configuration. Several heuristic functions …

Sensory Changes In Adults With Unilateral Transtibial Amputation, Judith B. Kosasih, Barbara Silver-Thorn

Biomedical Engineering Faculty Research and Publications

The purpose of this study was to describe the sensory changes in adults with unilateral transtibial amputation

(TTA), as any loss of sensation may have significant impact on the successful use of a prosthesis. Sensory modalities of light touch, deep pressure, vibration, and superficial pain (pinprick) were examined on the residual and contralateral limbs of 16 veterans with TTA. Six subjects demonstrated normal sensation on the contralateral limb and impaired sensation of superficial pain, vibration, and/or light touch on the residual limb. Superficial pain was the most frequently impaired sensation, and vibration and superficial pain sensation appeared to be age-dependent, …

Understanding The "Public Interest" Justification For Government Actions, Paul R. Verkuil

Articles

The article examines the concept of "public interest" as a justification for government actions, arguing that while the term has historically been a cornerstone of administrative law, its meaning has become increasingly ambiguous and subjective over time. The author traces the evolution of the public interest standard, from its origins in the New Deal era to its current use, and questions whether it can still serve as an objective standard for evaluating government behavior. The analysis highlights the tension between the public interest as a justification for government action and its susceptibility to political and bureaucratic influence.

Mapping Mediation: The Risks Of Riskin's Grid, Kimberlee K. Kovach, Lela P. Love

Articles

We use maps for orientation and guidance. A topographical map and compass guide us through unmarked terrain. To pass a bar exam, law students follow a course carefully mapped out by BAR/ BRI. To understand political configurations, we study maps of the world, indicating countries and states and their boundaries. Maps are important. They create paradigms or "boxes" within which to operate safely and efficiently. The universe a map depicts-what is put in and what is left out-must have an internal cohesion, logic, and accuracy. If not, maps misguide their users.
