Pulsed River Flooding Effects On Sediment Deposition In Breton Sound Estuary, Louisiana, Katherine Wheelock

LSU Master's Theses

Louisiana's deltaic coast is a dynamic sedimentary environment made vulnerable by Mississippi River channelization, which restricts freshwater, sediment, and nutrient inputs to adjacent estuaries. Freshwater diversions now reconnect some estuaries with historic fluvial sources, like Breton Sound basin, which receives Mississippi River suspended loads through the Caernarvon freshwater diversion. The project objectives were to quantify short-term sediment accumulation using sediment traps, evaluate sediment trap effectiveness, and compare long-term deposition using feldspar horizon markers and 210Pb dating to the annual sediment trap deposition. Magnitude and variations of sediment deposition at 14 sites were compared during an 18-month study in the upper …

Soil Particle-Size Analysis: A Comparison Of Two Methods, Lauren Williams-Caudle, Kristofor Brye, E. Moye Rutledge

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Knowing the proportion of particle sizes in soil is important to soil scientists and agronomists. The mixture of sand, silt, and clay influences water movement, solute transport, nutrient retention, and many other properties and processes in soil. The standard method for particle size determination is a somewhat time-consuming process. An equally accurate but shorter method would be appealing for many reasons. The objective of this study was to compare a standard method of particle-size analysis using a hydrometer to an abbreviated hydrometer method, which, instead of 12 h for the standard method, requires about 3 h to complete. Twenty-four soil …

Characterization Of The Interaction Of Gamma Cyclodextrin With Single-Walled Carbon Nanotubes, Gordon Chambers, Clodagh Carroll, Garrett Farrell, Alan Dalton, Mary Mcnamara, Marc In Het Panhuis, Hugh Byrne

Articles

In this study a number of composite-like samples of ç-cyclodextrin and HiPco carbon nanotubes were prepared. The first sample was prepared by a simple grinding procedure, which has been reported to cut HiPco carbon nanotubes. The other samples were obtained via a refluxing procedure analogous to similar studies on other fullerenes and ç-cyclodextrin. The samples were analyzed using absorption and Raman spectroscopy, and differential scanning calorimetry. The results presented show clear evidence of an intermolecular interaction between ç-cyclodextrin and single-walled carbon nanotubes.

The Lotic Intersite Nitrogen experiment (LINX) was a coordinated study of the relationships between North American biomes and factors governing ammonium uptake in streams. Our objective was to relate inter-biome variability of ammonium uptake to physical, chemical and biological processes. 2. Data were collected from 11 streams ranging from arctic to tropical and from desert to rainforest. Measurements at each site included physical, hydraulic and chemical characteristics, biological parameters, whole-stream metabolism and ammonium uptake. Ammonium uptake was measured by injection of '5~-ammonium and downstream measurements of 15N-ammonium concentration. 3. We found no general, statistically significant relationships that explained the variability …

Selberg's Trace Formula On The K-Regular Tree And Applications, Audrey Terras, Dorothy Wallace

Dartmouth Scholarship

We survey graph theoretic analogues of the Selberg trace and pretrace formulas along with some applications. This paper includes a review of the basic geometry of a k-regular tree E (symmetry group, geodesies, horocycles, and the analogue of the Laplace operator). A detailed discussion of the spherical functions is given. The spherical and horocycle transforms are considered (along with three basic examples, which may be viewed as a short table of these transforms). Two versions of the pretrace formula for a finite connected k-regular graph ×□Γ\Ξ are given along with two applications. The first application is to obtain an asymptotic …

Doe 1 V. City Of Murrieta: How The California Court Of Appeal Missed The Mark On Vicarious Liability For Sexual Torts Committed By On-Duty Police Officers, Tara L. Pennington

University of San Francisco Law Review

The California Supreme Court held that the first situation involves such a powerful use of authority that the city employing the officer can be held vicariously liable for his sexual torts. However, in Doe 1 v. City of Murrieta, the California Court of Appeal decided that the City cannot be held vicariously liable in the second situation.

Two papers examine risk management and its application to decision making as well as what researchers have learned over the past few decades in their theoretical investigations of risk. The remaining chapters examine how risk plays out in the particular markets in which it has a significant presence, including casino gambling enterprises, agricultural markets, auctions, and health insurance.

Retribution For Rats: Cooperation, Punishment, And Atonement, Michael A. Simons

Faculty Publications

(Excerpt)

To mobsters, he is a "rat"; to drug dealers, a "snitch." To school children, he is a "tattletale"; to corporate executives, a "whistleblower." To cops, he is an "informant"; to prosecutors, a "cooperator." By whatever name he is known, the person who betrays his associates to the authorities is almost universally reviled. In movies, on television, in literature, the cooperator embodies all that society holds in contempt: he is disloyal, deceitful, greedy, selfish, and weak.

The cooperator, though, has long been a mainstay of our criminal justice system. For centuries, criminal defendants have received leniency in return for testimony …

New Modified Smith Predictor Designs, Pauline Sourdille, Aidan O'Dwyer

Conference papers

By combining several existing modified Smith predictor structures, presented in a literature review, a generalised form of the Smith predictor is proposed. From this structure, excellent servo and regulator responses can be obtained by specifying three controller dynamic elements. Two new modified Smith predictor structures are presented with their associated tuning rules. The results of the simulations indicate that the two new designs give better overall responses than the original Smith predictor.

Comparison Of Process Identification Techniques In The Time And Frequency Domains, Tony Kealy, Aidan O'Dwyer

Conference papers

This paper describes ten methods to identify a mathematical model for a real process with a time delay. The process is the Process Trainer, PT326 from Feedback Instruments Limited. Six of the methods use step response data and one of the methods uses impulse response data for identification. Two of the methods use frequency response data and the final method uses information from relay-based experiments. The best results are obtained using a combined analytical and gradient method [6] in the frequency-domain and, in the time-domain, using the two-point algorithm [1] and a method proposed by Suganda et al. [5].

Analytical Ise Calculation And Optimum Control System Design, Tony Kealy, Aidan O'Dwyer

Conference papers

In control system theory, a performance index is a quantitative measure of the performance of a system and is chosen so that emphasis is given to the important system parameters. In this paper, the authors demonstrate two methods to determine analytically the ISE performance index value for a FOPDT process model under PI control. The ability of proportional/integral (PI) and proportional/integral/derivative (PID) controllers to compensate most practical industrial processes has led to their wide acceptance in industrial applications. The most direct way to set up PI/PID controller parameters is the use of tuning rules. The second part of this paper …

Theses and Dissertations

In Ecuador, there is a grave socioeconomic nutritional problem, and it is seen clearest in Imbabura province in the communities of Cuambo and La Rinconada. One of the biggest problems is inadequate food, due principally to the poor food storage and conservation habits. Considering this problem, it is necessary to deepen the knowledge of improved traditional techniques for storing and conserving food, through which families can store and manage their product better, controlling and avoiding losses due to insects, rodents, and climate, and guaranteeing conservation of the same. The investigation was oriented to implement alternative, improved storage and conservation technologies …

Legal Separation: The Relationship Between Law School And The Central University In The Late Nineteenth Century, Mark Bartholomew

Journal Articles

Using Yale Law School as an example, this Article describes the interaction between university-affiliated law schools and the larger university during a crucial period in the development of legal education: the last third of the nineteenth century. At the same time, the Article contrasts Yale with other law schools of the day to show what made Yale unique and how Yale’s nineteenth-century idiosyncrasies would come to shape legal education at other schools in the twentieth century. Part I examines the university administration’s attitude toward the law school and how it typified law school-university relations in the late nineteenth century. Part …

Differentiating Instruction Using Authentic, Performance Assessments And Technology Integration, Cynthia Seberg

Graduate Research Papers

A major challenge in education today is to be able to reach and teach all learners. Methodologies and strategies come and go. The philosophy of differentiated instruction, while not new, is being bandied about as the answer to working with all students of all abilities. The beliefs associated with differentiated instruction envelope methodologies and strategies associated with authentic assessment, performance-based assessment, and technology integration.

A common bond inherent within these philosophies is the growing emphasis on assessing students based on their ability to perform real-life tasks, and technology integration is the connecting link. Educators must become facilitators of meaningful learning …

Motivating Students With Digital Portfolios, Rochelle Christine Duwa

Graduate Research Papers

As the drop out rates of high schools across the country reach 30 percent, the need for teachers to be able to motivate students becomes increasingly important. Alternative assessments (especially performance based) have become a popular trend in schools and have proven to give a more accurate display of students' skills and knowledge than standardized tests. This paper investigates the different kinds of digital or electronic portfolios, and the process of creating and implementing digital portfolios in order to help determine the role they could play as a method of alternative assessment as well as motivating students.

Putting The Best Possible Teacher In The Classroom : Through Reflection And Self-Evaluation, Renee Fisher

Graduate Research Papers

Over the span of five months, an elementary school teacher uses reflection and self-evaluation methods to review her teaching. The process encourages improvement in areas concurrent with the Iowa Teaching Standards. Including a current portfolio, the teacher uses the medium of videotape to self-evaluate her teaching style and the evaluation by building administrator. Current research in teacher evaluation lends support to the need for self-evaluation. The completed portfolio becomes a working document chronicling the teacher's work in the classroom and career field. The results show the improvement that has occurred, along with areas to advance in.

Graduate Research Papers

As I study leadership and reflect on the possibility of becoming a school administrator, I am convinced that my personal priorities and values will be challenged and must be clear. An administrative position encompasses a wide variety of responsibilities, skills, and wisdom. Most importantly the role also requires effective judgments and decisions to be made that are financially and legally sound. I continue to be introduced to many new perceptions and views of administrative leadership. Theories of leadership qualities and actions abound. I realize the importance of studying and understanding many different leadership ideas and approaches. It is important to …

Address Register Assignment For Reducing Code Size, M. Kandemir, M. J. Irwin, G. Chen, J. Ramanujam

Faculty Publications

In DSP processors, minimizing the amount of address calculations is critical for reducing code size and improving performance since studies of programs have shown that instructions that manipulate address registers constitute a significant portion of the overall instruction count (up to 55%). This work presents a compiler-based optimization strategy to reduce the code size in embedded systems. Our strategy maximizes the use of indirect addressing modes with post-increment and post-decrement capabilities available in DSP processors. These modes can be exploited by ensuring that successive references to variables access consecutive memory locations. To achieve this spatial locality, our approach uses both …

The Perception Of Harmony In Combinations Of Blinking Visual Stimuli., Katharine Tepe, Donald J. Polzella, Greg C. Elvers

Psychology Faculty Publications

Research on the perception of musical harmony indicates that combinations of tones tend to be judged consonant when their respective frequencies are reducible to simple ratios. This phenomenon was studied in the visual mode by using combinations of two blinking lights as stimuli. Eight, two-light combinations were created whose frequency ratios corresponded to those of eight common musical intervals, e.g., octave, fifth. In a pair comparison task, participants judged which one of two, two-light combinations appeared more harmonious or blended. The judgments were compared to those obtained from studies of musical harmony by regressing the scaled auditory preferences onto the …
