Consortia Vs Reform: Creating Congruence, Margaret Landesman, Johann Van Reenen

University Libraries & Learning Sciences Faculty and Staff Publications

The inability of research libraries to offer the collections their users desire has become more pronounced each year. In response, libraries have moved in two directions: the rapidly growing consortial movement and the movement to advocate and support reforms in scholarly communication. However, if libraries do not pay careful attention, these two directions may, at least partially, cancel one another out.

A Neural Network Methodology For Path Planning And Coordination Of Car-Like Robots, Prasanna Venkatesan Sadagopan

Masters Theses

"A car-like indoor mobile robot is a kinematically constrained robot that can be modeled as a 2D object translating and rotating in the horizontal plane among well- defined obstacles. The kinematic constraints impose that the linear velocity of the robot is along its main axis (no sideways motion is possible) and restrict the range of admissible values for the steering angle. The goal of this study is to combine neural network techniques and motion planning algorithms to create a new methodology for coordinating the motion of multiple car-like robots avoiding collision with polygonal obstacles in a work environment. An incremental …

Thickness Variation Of Self-Processing Acrylamide-Based Photopolymer And Reflection Holography, F. O'Neill, Justin Lawrence, J. Sheridan

Articles

There are many types of holographic recording material. The acrylamide-based recording material examined here has one significant advantage: it is self-processing. This simplifies the recording process and enables holographic interferometry to be carried out without the need for complex realignment procedures. However, the effect that the polymerization process has on the grating thickness must be examined. This question is fundamental to the material's use in holographic optical elements, as thickness variations affect the replay conditions of the produced elements. This paper presents a study of this thickness variation and reports for the first time the production of reflection holographic gratings …

Production Of A Signal By Irradiated Cells Which Leads To A Response In Unirradiated Cells Characteristic Of Initiation Of Apoptosis, Fiona Lyng, C. Seymour, C. Mothersill

Articles

This study investigated the ability of medium from irradiated cells to induce early events in the apoptotic cascade, such as mobilization of intracellular calcium, loss of mitochondrial membrane potential and increase in reactive oxygen species, in cells which were never exposed to radiation. Medium from irradiated human keratinocytes was harvested and transferred to unirradiated keratinocytes. Endpoints characteristic of the initiation of apoptosis were monitored for a period of 24 h following medium transfer. Clonogenic survival was also measured. Rapid calcium fluxes (within 30 s), loss of mitochondrial membrane potential, increases in reactive oxygen species (from 6 h after medium transfer), …

An Extension Of Zermelo's Model For Ranking By Paired Comparisons, Christopher P. Grant, Gregory R. Conner

Faculty Publications

In 1929, Zermelo proposed a probabilistic model for ranking by paired comparisons and showed that this model produces a unique ranking of the objects under consideration when the outcome matrix is irreducible. When the matrix is reducible, the model may yield only a partial ordering of the objects. In this paper, we analyse a natural extension of Zermelo's model resulting from a singular perturbation. We show that this extension produces a ranking for arbitrary (nonnegative) outcome matrices and retains several of the desirable properties of the original model. In addition, we discuss computational techniques and provide examples of their use.

Dan Cooper, American Designer (1901-1965), Diane Joyce Montenegro

Open Access Master's Theses

Dan Cooper (1901-1965) merits greater attention than he has received for his contributions to twentieth-century American interior design. During his forty-one-year career, he was a keen observer of changes in American society and was in the vanguard of interior designers offering attractive and usable products.

From 1924 to 1965, Cooper decorated the interiors of large private residences, hotels, public spaces, government housing projects, and corporate headquarters as well as several modes of transport. He helped validate his chosen profession by setting standards and advocating solid business practices. He offered furniture, fabrics, and accessories for almost every pocket book.

Bismuth(Iii) Oxide Perchlorate Promoted Rearrangement Of Epoxides To Aldehydes And Ketones, Ram Mohan, Andrew Anderson, Jesse Blazek, Parie Garg, Brian Payne

Scholarship

Aryl-substituted epoxides and aliphatic epoxides with a tertiary epoxide carbon undergo smooth rearrangement in the presence of 10–50 mol% bismuth(III) oxide perchlorate, BiOClO₄•xH₂O, to give carbonyl compounds. The rearrangement is regioselective with aryl substituted epoxides and a single carbonyl compound arising from cleavage of benzylic C―O bond is formed. BiOClO_4•xH₂O is relatively non-toxic, insensitive to air and inexpensive, making this catalyst an attractive alternative to more corrosive and toxic Lewis acids such as BF₃•Et₂O or InCl₃ currently used to effect epoxide rearrangements.

The Discovery-Oriented Approach To Organic Chemistry. 3. Boron-Trifluoride Catalyzed Rearrangement Of Cis- And Trans-Stilbene Oxides. An Exercise In 1H Nmr Spectroscopy For Sophomore Organic Laboratories, Ram Mohan, Erik Sgariglia, Regina Schopp, Kostas Gavardinas

Scholarship

Epoxides, or oxiranes, are among the most versatile intermediates in organic synthesis. Yet very few examples of laboratory experiments involving reactions of epoxides are to be found in lab texts. We have developed a discovery-oriented laboratory experiment that involves the rearrangement of both cis- and trans-stilbene oxides with boron trifluoride etherate. The identity of the product can be easily determined by ¹H NMR spectroscopy and, in case of the trans isomer, by preparation of the semicarbazone derivative as well. In spite of the simplicity of the experiment, the element of discovery ensures that student interest and enthusiasm are retained.

Scene-Based Nonuniformity Correction With Video Sequences And Registration, Russell C. Hardie, Majeed M. Hayat, Earnest Armstrong, Brian Yasuda

Electrical and Computer Engineering Faculty Research and Publications

We describe a new, to our knowledge, scene-based nonuniformity correction algorithm for array detectors. The algorithm relies on the ability to register a sequence of observed frames in the presence of the fixed-pattern noise caused by pixel-to-pixel nonuniformity. In low-to-moderate levels of nonuniformity, sufficiently accurate registration may be possible with standard scene-based registration techniques. If the registration is accurate, and motion exists between the frames, then groups of independent detectors can be identified that observe the same irradiance (or true scene value). These detector outputs are averaged to generate estimates of the true scene values. With these scene estimates, and …

Relative Impact Of Various Sources Of Pharmacokinetic And Pharmacodynamic Variability On Warfarin Response, Shashikanth Gannu

Open Access Master's Theses

Warfarin is widely used oral anticoagulant and its pharrnacokinetic (PK) and pharrnacodynamic (PD) properties have been extensively studied. It has a narrow therapeutic index and displays poor quality of treatment due to its complex pharmacology and wide inter and intraindividual variability in the dose-response relationship.

This study developed an integrated PK-PD model using STELLA® to describe the dose concentration- effect relationship for warfarin. This model used previously reported\ population PK and PD models and parameter values to generate dose-response data. A one compartment stereo-specific semi-physiological PK model with zero-order drug input was linked to an indirect PD model describing the …

Stochastic Stability Of The Continuous-Time Extended Kalman Filter, K. Reif, S. Gunther, Edwin E. Yaz, R. Unbehauen

Electrical and Computer Engineering Faculty Research and Publications

he error behaviour of the extended Kalman filter is analysed. It is proved that the estimation error remains bounded if the system satisfies a detectability condition and both the initial estimation error and the disturbing noise terms are small enough. Moreover, some selected cases with both bounded and unbounded estimation error are demonstrated by numerical simulations.

A Predictive Fuzzy-Neural Autopilot For The Guidance Of Small Motorised Marine Craft, Ralph Richter

School of Engineering, Computing and Mathematics Theses

This thesis investigates the design and evaluation of a control system, that is able to adapt quickly to changes in environment and steering characteristics. This type of controller is particularly suited for applications with wide-ranging working conditions such as those experienced by small motorised craft. A small motorised craft is assumed to be highly agile and prone to disturbances, being thrown off-course very easily when travelling at high speed 'but rather heavy and sluggish at low speeds. Unlike large vessels, the steering characteristics of the craft will change tremendously with a change in forward speed. Any new design of autopilot …

The Use Of Two Mixture Fractions To Treat Coal Combustion Products In Turbulent Pulverized-Coal Flames, Daniel V. Flores, Thomas H. Fletcher

Faculty Publications

Previous coal combustion models using assumed-shape PDF's to treat turbulence-chemistry interactions have used only one progress variable to treat products from coal reactions. This assumes that the products of all coal reactions have the same composition. However. the composition of the combustion products of coal particles is known to vary with burnout, especially between devclatilization and char oxidation. In this work, two progress variables were implemented which distinguish between the products of devolatilization and those of char oxidation. This new approach requires as input the specified volatile content and elemental release during devolatilization. The values for these parameters were estimated …

What We Do When We Do What We Do And Why We Do It, Leo Katz

San Diego Law Review

But what exactly am I talking about when I speak of symmetry and asymmetry in law and ethics? It may be clear enough what those notions mean in geometry, but how are they to be understood in law, or

for that matter in ethics, more generally? Let me start with symmetry- its meaning and the benefits of exploring it. Rather than try to define the

term, however, I will offer what I think is a pretty self-explanatory example of the phenomenon as it arises in law and ethics. It is an example that has fascinated me for quite some time: …

Exploring And Exploiting Models Of The Fitness Landscape: A Case Against Evolutionary Optimization, Jonathan Paul Moore

School of Engineering, Computing and Mathematics Theses

In recent years, the theories of natural selection and biological evolution have proved popular metaphors for understanding and solving optimization problems in engineering design. This thesis identifies some fundamental problems associated with this use of such metaphors. Key objections are the failure of evolutionary optimization techniques to represent explicitly the goal of the optimization process, and poor use of knowledge developed during the process. It is also suggested that convergent behaviour of an optimization algorithm is an undesirable quality if the algorithm is to be applied to multimodal problems. An alternative approach to optimization is suggested, based on the explicit …
