A generic applications subroutine library for the MPP

A new methodology to increase the utility of the Massively Parallel Processor (MPP) was developed, and is presented as an addition to the current methods of using the MPP. This methodology provides for the development of an MPP side abstraction layer that is callable from any host side high level language. Routines in the abstraction layer have the option of using a powerful software tool for accessing the stager as virtual memory. An additional abstraction layer that allows for remote access to the MPP via DECnet is discussed. This integrated approach to programming the MPP is a valuable tool for the implementation of interactive user driver systems that require the computational capabilities of the MPP as well as a controlled user view. It is expected that this methodology will be used to integrate the MPP into many such systems, and thus promote greater use of the MPP by scientific researchers who are accustomed to user friendly environments

Asteroseismic study of solar-like stars: A method of estimating stellar age

Asteroseismology, as a tool to use the indirect information contained in stellar oscillations to probe the stellar interiors, is an active field of research presently. Stellar age, as a fundamental property of star apart from its mass, is most difficult to estimate. In addition, the estimating of stellar age can provide the chance to study the time evolution of astronomical phenomena. In our poster, we summarize our previous work and further present a method to determine age of low-mass main-sequence star.Comment: 2 pages, 1 figures, submitted to IAUS25

Animated computer graphics models of space and earth sciences data generated via the massively parallel processor

The capability was developed of rapidly producing visual representations of large, complex, multi-dimensional space and earth sciences data sets via the implementation of computer graphics modeling techniques on the Massively Parallel Processor (MPP) by employing techniques recently developed for typically non-scientific applications. Such capabilities can provide a new and valuable tool for the understanding of complex scientific data, and a new application of parallel computing via the MPP. A prototype system with such capabilities was developed and integrated into the National Space Science Data Center's (NSSDC) Pilot Climate Data System (PCDS) data-independent environment for computer graphics data display to provide easy access to users. While developing these capabilities, several problems had to be solved independently of the actual use of the MPP, all of which are outlined

A Way Out: The History of the Outing Program from the Haskell Institute to the Phoenix Indian School

From the earliest years of the United States, its leaders wrestled with the perceived need to assimilate Indian peoples into American society. Many believed that Indians in their natural condition were cultural primitives incapable of taking part in national life. However, with proper guidance they could be elevated to a level of civilization that would allow them to join the national family. After the conclusion of the Indian Wars in the 1880\u27s, the United States government began to address the continued Indian problem by establishing Indian boarding schools. Indian children attended school to learn to behave as white, Christian and productive members of society. Students attending the off-reservation boarding schools, like the Haskell Institute in Lawrence, Kansas and the Phoenix Indian School in Phoenix, Arizona were taught the fundamentals of education and a trade so they could eventually provide for themselves and their families without government support. In order to further reinforce these principles, students participated in the outing program, where they could work for local white families. This program allowed students to develop working relationships with whites, earn spending money, and practice what they learned at school in a practical setting. While this program was initially designed to quickly assimilate native children into white, middle class society, the program ensnared Native Americans in a constant state of wage labor. Students who graduated from the boarding schools often could not find jobs within their trade and many who returned home were ostracized for not knowing their traditional language and customs. These students, being caught between two worlds, were essentially assimilated as unskilled and inexpensive laborers willing to work for white employers. The outing program partially achieved the goal of assimilation, but Indians did not achieve equal standing with whites. Instead, the outing program assimilated Indians by becoming common laborers for whites

A Transition Program for Hearing-Impaired Students: Their Perceptions of the Process of Change

This study was conducted in an effort to gain an understanding of the experiences of hearing- impaired students participating in a year-long transition program, specifically addressing students\u27 own perceptions of personal change. Ten hearing-impaired students volunteered to participate as informants in the qualitative study. A series of in-depth interviews was conducted throughout the course of the transition program. Videotapes and transcripts of the interviews were then analyzed to assess patterns or themes of experiences and change common to the informants. A number of themes or dimensions of change occurring over time were found to be consistent for all informants, including issues of identity, personal values, family and social relationships, communication, plans and expectations for the future, and perceptions of change. Segments from inter views are presented, and implications are dis cussed for the issues of transition program development, as well as enhancement of psychosocial development

The Varied carols I hear : The music of the New Deal in the West

The Federal Music Project and subsequent WPA Music Programs served as components of President Franklin D. Roosevelt\u27s New Deal efforts to combat the economic devastation precipitated by the Great Depression. Operating during the years 1936 to 1943, these programs that engaged unemployed musicians mirrored similar efforts of the Federal Theatre, Art and Writers\u27 Projects. Though the Federal Music Project proved to be the largest of the cultural programs in terms of both employment and attendance, to date it has received the least attention from scholars. This dissertation demonstrates that, given the societal landscape of 1930s America, a regional perspective is imperative to an analysis of the music programs. And, contrary to earlier histories, the Federal Music Projects and WPA Music Programs of the West were successful in expressing the ethnic and cultural diversity of the region, thus achieving a primary goal of the Roosevelt administration

Sodium bicarbonate improves 4 km time trial cycling performance when individualised to time to peak blood bicarbonate in trained male cyclists

The aim of this study was to investigate the effects of sodium bicarbonate (NaHCO3) on 4 km cycling time trial (TT) performance when individualised to a predetermined time to peak blood bicarbonate (HCO3−). Eleven male trained cyclists volunteered for this study (height 1.82 ± 0.80 m, body mass (BM) 86.4 ± 12.9 kg, age 32 ± 9 years, peak power output (PPO) 382 ± 22 W). Two trials were initially conducted to identify time to peak HCO3− following both 0.2 g.kg−1 BM (SBC2) and 0.3 g.kg−1 BM (SBC3) NaHCO3. Thereafter, on three separate occasions using a randomised, double-blind, crossover design, participants completed a 4 km TT following ingestion of either SBC2, SBC3, or a taste-matched placebo (PLA) containing 0.07 g.kg−1 BM sodium chloride (NaCl) at the predetermined individual time to peak HCO3−. Both SBC2 (−8.3 ± 3.5 s; p < 0.001, d = 0.64) and SBC3 (−8.6 ± 5.4 s; p = 0.003, d = 0.66) reduced the time to complete the 4 km TT, with no difference between SBC conditions (mean differ- ence = 0.2 ± 0.2 s; p = 0.87, d = 0.02). These findings suggest trained cyclists may benefit from individualising NaHCO3 ingestion to time to peak HCO3− to enhance 4 km TT performance
