A Parallel Processor System for Nuclear Shell-Model Calculations

This thesis describes the design and implementation of a dedicated parallel processor system for nuclear shell-model calculations. The purpose of these calculations is to determine nuclear energy eigenvalues by the tridiagonalisation of the nuclear Hamiltonian matrix using the Lanczos method. The Theoretical Nuclear Structure group at Glasgow University's Physics Department would normally perform this type of calculation on a high-performance main-frame computer. However these machines have limitations which restrict the number and scope of the calculations that can be performed. The Shell Model Processor system consists of a Multiple Microprocessor Unit (MMPU) driven by a highly pipelined dedicated front-end processor. The MMPU has a modular, moderately coupled, MIMD architecture based on autonomous processing modules. The elements within the system communicate via three shared buses. The front-end is responsible for determining the position of non-zero elements within the Hamiltonian matrix. Once the position of an element has been found it is passed to one of the free processing modules within the MMPU. The processing module then determines the value of the matrix element and performs the appropriate arithmetic to accumulate the resultant Lanczos vector. Two such processing modules have been developed. The most recently developed module is based on two MC68000 16/32 bit microprocessors. In addition there are two supervisory processor modules, one of which controls the front-end and also assists it in its function. The other module has privileged system capabilities and is responsible for supervising the system as a whole. The system has been successfully tested and performance figures are presented. The future expansion of the system to allow it to perform larger calculations is also discussed

Qcompiler: quantum compilation with CSD method

In this paper, we present a general quantum computation compiler, which maps any given quantum algorithm to a quantum circuit consisting a sequential set of elementary quantum logic gates based on recursive cosine-sine decomposition. The resulting quantum circuit diagram is provided by directly linking the package output written in LaTex to Qcircuit.tex $$. We illustrate the use of the Qcompiler package through various examples with full details of the derived quantum circuits. Besides its generality and simplicity, Qcompiler produces quantum circuits which reflect the symmetry of the systems under study

Protecting the Past: A Comparative Study of the Antiquities Laws in the Mid-South

Governmental efforts to protect antiquities can be found in the early twentieth century; however, the most significant policy efforts began in the late 1960s and early 1970s. This manuscript focuses on the properties/items protected under current statutes in Arkansas, Louisiana, and Texas and provides background on major federal policies. Moreover, it addresses the penalties imposed for violating these regulations. The efforts made to enforce these rules are also addressed along with suggestions for improving implementation of antiquities policies in all three states

Twelve‐year tillage and crop rotation effects on yields and soil chemical properties in northeast Iowa

Long‐term tillage and crop management studies may be useful for determining crop production practices that are conducive to securing a sustainable agriculture. Objectives of this field study were to evaluate the combined effects of crop rotation and tillage practices on yield and changes in soil chemical properties after 12 years of research on the Clyde‐Kenyon‐Floyd soil association in northeastern Iowa. Continuous corn (Zea mays L.) and a corn‐soybean [Glycine max L. (Herr.)] rotation were grown using moldboard plowing, chisel plowing, ridge‐tillage, or no‐tillage methods. Tillage and crop rotation effects on soil pH, Bray P1, 1M NH4OAc exchangeable K, Ca, and Mg, total C, and total N in the top 200 mm were evaluated. Profile NO3‐N concentrations were also measured in spring and autumn of 1988. Crop yields and N use efficiencies were used to assess sustainability. Bray P1 levels increased, but exchangeable K decreased for all cropping and tillage methods. Nutrient stratification was evident for no‐tillage and ridge‐tillage methods, while the moldboard plowing treatment had the most uniform soil test levels within the 200 mm management zone. Chisel plowing incorporated fertilizer to a depth of 100 mm. Soil pH was lower with continuous corn than with crop rotation because of greater and more frequent N applications. Profile NO3‐N concentrations were significantly different for sampling depth and among tillage methods in spring 1988. In autumn the concentrations were significantly different for sampling depth and for a rotation by tillage interaction. Estimated N use efficiencies were 40 and 50 kg grain per kg N for continuous corn, and 48 and 69 kg grain per kg N for rotated corn in 1988 and 1989, respectively. The results suggest that P fertilizer rates can be reduced, but K rates should probably be increased to maintain soil‐test levels for this soil association. Crop rotation and reduced tillage methods such as ridge‐tillage or chisel plowing appear to meet the criteria for sustainable agriculture on these soils

Pay Increases Subsequent to FMLA Leave: The Role of Organizational Justice

Research indicates the importance of studying organizational justice and its impact. Further, research has indicated a relationship between perceptions of organizational justice and pay increase decisions. However, the present research is the first to incorporate the Family and Medical Leave Act (FMLA) leave into the equation. In short, this research addressed whether an employee\u27s absence for FMLA-covered reasons impacts the perceived justice of subsequent pay increases for that employee. Specifically, it was hypothesized that the employee\u27s length of absence, tenure, performance, and/or pay increase would impact justice perceptions. Participants evaluated vignettes manipulating these factors, then rated the fairness of pay increase decisions. Results revealed that the employee\u27s performance interacted with the amount of pay increase to account for the largest amount of variance injustice perceptions. However, a main effect for pay increase, an interaction between performance and the length of the employee\u27s leave, and an interaction between performance, tenure, the length of the employee\u27s leave, and the pay increase decision were observed. Finally, among employees who received a full pay increase, performance was the strongest predictor of justice perceptions

Implementation of Raman spectroscopy at manufacturing scale: Overcoming modeling challenges while implementing advanced process control

In order to improve glycation control in our new high intensity platform process, we investigated implementation of Raman spectroscopy to monitor and control glucose at low levels throughout the process. Using Raman allows a way to measure glucose near real time which in turn allows for a more responsive and flexible control algorithm. Prior literature has shown connections between elevated glucose levels and glycation when in presence of high protein concentrations, which was indicative of our process. Using Raman along with advanced process control (APC), allowed us the flexibility to reduce glycation back towards historical process levels. We will share a case study of how Raman models were built using the RXN2-785 system and later deemed unresponsive due to high levels of fluorescence on day 5 of a 14 day process. We will discuss potential sources of the fluorescence and provide a multi-product comparison for perspective. Additional development effort was required in tight time frame to derive a manufacturing ready solution to this challenging problem. We will describe what that solution was and how we were able to successfully create new models with errors acceptable within our process control strategy design. Lastly, we will demonstrate how controlling glucose at lower levels during the process impacted glycation. Our work ended with two engineering runs at 17,000L scale where we used Raman spectroscopy to successfully monitor and control glucose at a lower set point and effectively lower glycation by 40% of its original value

State Regulation of Franchising: The Washington Experience Revisited

Thirty-six years ago, and one year after Washington became the second state in the nation to enact a statute regulating franchise relationships, Professor Donald S. Chisum wrote the seminal article on franchising in Washington, State Regulation of Franchising: The Washington Experience. Professor Chisum\u27s article has been one of the few reference sources for Washington franchise law, and it has been the primary source relied on by courts addressing claims under Washington\u27s Franchise Investment Protection Act (FIPA). Since Professor Chisum originally published his article, the Federal Trade Commission (FTC) has promulgated and amended regulations governing the sale of franchises nationally, and two different groups have drafted uniform franchise acts. In Washington, the legislature significantly amended FIPA in 1991, and courts have addressed some of the unresolved issues under the statute. This Article assesses the changed state of franchise law in Washington. Part II considers the economic impact of franchising and the need for a review of franchising in Washington. Part III reviews the historical foundation for Washington\u27s current franchise laws, the context in which they were created, and the changes to franchise law that drive our modem understanding of FIPA today. Part IV addresses the current regulatory scheme in Washington, including practical considerations such as franchise registration, disclosure, and state enforcement powers. Finally, Part V addresses civil liability for violations of FIPA\u27s registration, disclosure, and relationship provisions
