Monte Carlo simulation of the classical two-dimensional one component plasma

Monte Carlo simulation, lattice dynamics in the harmonic approximation, and solution of the hypernetted chain equation were used to study the classical two-dimensional one component plasma. The system consists of a single species of charged particles immersed in a uniform neutralizing background. The particles interact via a l/r potential, where r is the two dimensional separation. Equations of state were calculated for both the liquid and solid phases. Results of calculation of the thermodynamic functions and one and two particle correlation functions are presented

Report from the MPP Working Group to the NASA Associate Administrator for Space Science and Applications

NASA's Office of Space Science and Applications (OSSA) gave a select group of scientists the opportunity to test and implement their computational algorithms on the Massively Parallel Processor (MPP) located at Goddard Space Flight Center, beginning in late 1985. One year later, the Working Group presented its report, which addressed the following: algorithms, programming languages, architecture, programming environments, the way theory relates, and performance measured. The findings point to a number of demonstrated computational techniques for which the MPP architecture is ideally suited. For example, besides executing much faster on the MPP than on conventional computers, systolic VLSI simulation (where distances are short), lattice simulation, neural network simulation, and image problems were found to be easier to program on the MPP's architecture than on a CYBER 205 or even a VAX. The report also makes technical recommendations covering all aspects of MPP use, and recommendations concerning the future of the MPP and machines based on similar architectures, expansion of the Working Group, and study of the role of future parallel processors for space station, EOS, and the Great Observatories era

How do they do it? Understanding back office efficiency savings made by English councils

Purpose – The purpose of this paper is to illustrate the back office efficiency savings made by English councils during the 2004 Spending Review (SR04) period in order to consider the relationship between service delivery, audit and inspection and, efficiency programmes in local government. It considers three research questions: the use of secondary data, the relationship between efficiency savings and contextual factors, and the influence of audit and inspection in delivering efficient public services. Design/methodology/approach – Through statistical analysis the paper discusses the secondary analysis of publicly available sets of administrative data about local councils in England. These datasets are the annual efficiency statements (AES) taken from records made by each council. The paper discusses through the analysis of the AES the degree of efficiency savings and service improvements in English councils and whether efficiency savings are influenced by internal or external contextual factors. Findings – The paper illustrates that secondary data is a useful source of data, but finds that although councils have achieved the efficiency savings set there is no relationship with the contextual factors. The paper considers the influence of audit and inspection, suggesting that the focus has been on meeting the target rather than local needs. Originality/value – This paper aims to contribute to the debate regarding the use of performance indicators, audit and inspection and efficiency achievement within local government. The paper starts to explore the implication in the UK where, after a decade of use, the influence of these is reducing dramatically

The Luminous Convolution Model as an alternative to dark matter in spiral galaxies

The Luminous Convolution Model (LCM) demonstrates that it is possible to predict the rotation curves of spiral galaxies directly from estimates of the luminous matter. We consider two frame-dependent effects on the light observed from other galaxies: relative velocity and relative curvature. With one free parameter, we predict the rotation curves of twenty-three (23) galaxies represented in forty-two (42) data sets. Relative curvature effects rely upon knowledge of both the gravitational potential from luminous mass of the emitting galaxy and the receiving galaxy, and so each emitter galaxy is compared to four (4) different Milky Way luminous mass models. On average in this sample, the LCM is more successful than either dark matter or modified gravity models in fitting the observed rotation curve data. Implications of LCM constraints on populations synthesis modeling are discussed in this paper. This paper substantially expands the results in arXiv:1309.7370.Comment: Implications of LCM constraints on populations synthesis modeling are discussed in this paper.
