Testing Programs That Contain OpenMP Directives

OpenMP is a standard of compiler directives for C and Fortran programs that allow a developer to parallelize existing code. In this master\u27s project, the topic of tests for code that has been parallelized using OpenMP is addressed. How should a developer test a program to make sure that the directives have not modified the expected results of the code

All the King’s Horses, All the King’s Elephants: The Fates of Royal Animals in Nepal’s Post-Monarchy Period

In May of 2008, Nepal’s 240-year-old monarchy was legally dissolved. In the wake of this dissolution, the new interim government sought to replace royal institutions, procedures, and ceremonies with new, parallel processes. One unexpected royal legacy that politicians needed to resolve was that of the former royal animals that had been connected to the position of the King. The king of Nepal and palace institutions had been responsible for the welfare of a range of animals: private royal horses, a palace dairy herd, elephants in Chitwan, and an aviary of pheasants. Many of Nepal’s ex-royal animals have survived for years after the monarchy’s collapse, and many of them were left vulnerable, with no one clearly responsible for or dedicated to them in the new political context. The peculiar and marginalized fates of Nepal’s ex-royal animals highlight the profound institutional complexity the monarchy once entailed, and the far-reaching consequences of its dissolution. They also reveal the grudging and complex ways that parliamentary politicians and bureaucrats have handled some of the more inconvenient legacies of the institution they eliminated

A preliminary design study of supersonic through-flow fan inlets

From Mach 3.20 cruise propulsion systems, preliminary design studies for two supersonic through-flow fan primary inlets and a single core inlet were undertaken. Method of characteristics and one dimensional performance techniques were applied to assess the potential improvements supersonic through-flow fan technology has over more conventional systems. A fixed geometry supersonic through-flow fan primary inlet was found to have better performance than a conventional inlet design on the basis of total pressure recovery, air flow, aerodynamic drag and size and weight

A supersonic through-flow fan engine airframe integration study

Engine airframe integration effects are investigated for supersonic through-flow fan engines installed on a Mach 3.20 supersonic cruise vehicle. Six different supersonic through-flow fan engine installations covering the effects of engine size, nacelle contour, nacelle placement, and approximate bypass plume effects are presented. The different supersonic through-flow fan installations are compared with a conventional turbine bypass engine configuration on the same basic airframe. The supersonic through-flow fan engine integrations are shown to be comparable to the turbine bypass engine configuration on the basis of installed nacelle wave drag. The supersonic through-flow fan engine airframe integrated vehicles have superior aerodynamic performance on the basis of maximum lift-to-drag ratio than the turbine bypass engine installation over the entire operating Mach number range from 1.10 to 3.20. When approximate bypass plume modeling is included, the supersonic through-flow fan engine configuration shows even larger improvements over the turbine bypass engine configuration

Returns to investors in stocks in new industries

We examine the returns to investors in publicly traded stock in new industries. We examine data from the United States on sellers of own-brand personal computers, airlines and airplane manufacturers, automobile manufacturers, railroads, and telegraphs. We find that a relatively small number of companies generate outstanding returns and many firms fail. Firms in new industries typically have high volatility of individual stocks' returns. Compared with indexes for the same period, expected returns of firms are higher for two industries, lower for one industry and roughly the same for two industries. Portfolios of firms in new industries generally have lower Sharpe ratios than the overall market.Investments
