    An interactive NASTRAN preprocessor

    A Langley Research Center version of NASTRAN Level 15.1.0 designed to provide the analyst with an added tool for debugging massive NASTRAN input data is described. The program checks all NASTRAN input data cards and displays on a CRT the graphic representation of the undeformed structure. In addition, the program permits the display and alteration of input data and allows reexecution without physically resubmitting the job. Core requirements on the CDC 6000 computer are approximately 77,000 octal words of central memory

    Computer program provides improved longitudinal response analysis for axisymmetric launch vehicles

    Get PDF
    Computer program calculates axisymmetric launch vehicle steady-state response to axisymmetric sinusoidal loads. A finite element technique is utilized to construct the total launch vehicle stiffness matrix and mass matrix by subdividing the prototype structure into a set of axisymmetric shell components, fluid components, and spring-mass components

    Community Response Strategies for Environmental Problems of Water Supply and Wastewater Disposal in Fairbanks, Alaska

    This report examines the history of the response strategies of the Fairbanks, Alaska, community to problems of water supply and wastewater disposal. Fairbanks is significant since it is the largest settlement in the northern subarctic and arctic regions of North America. Today, the City of Fairbanks and the surrounding urban area have a combined population of over 40,000

    Biology and Fishery for Atlantic Thread Herring, Opisthonema oglinum, along the North Carolina Coast

    Get PDF
    Thread herrings, Opisthonema spp., are small, nearshore, pelagic clupeid fishes that form dense, surface schools in tropical to subtropical coastal waters. Ecologically, thread herrings form an important forage base for many large, predatory fishes (Finucane and Vaught, 1986). Commercially, thread herrings are targeted by artisanal to moderate-sized seine fisheries off the coasts of Ecuador and Peru (Patterson and Santos, 1992), Costa Rica (Stevenson and Carranza, 1981), Venezuela, the continental margins of the Caribbean, the Gulf of Mexico, and near the islands of Cuba, Hispaniola, Puerto Rico, Jamaica, and Trinidad (Reintjes, 1978). Most of the catch is reduced to fish meal and fish oil (Patterson and Santos, 1992), although minor quantities are used for human consumption (Reintjes, 1978)

    The Anchorage, Alaska Veterans Court and Recidivism: July 6, 2004 – December 31, 2010

    Get PDF
    In July 2004 Anchorage, Alaska started one of the first veterans courts in the United States. That court has now been in continuous operation for over seven years. This Comment briefly describes the steps taken to establish the Alaska Veterans Court and how the court operates. An overview of the characteristics of participants in and graduates from the court is provided, followed by statistics concerning the effect of the court on recidivism. Several potential future areas of study concerning this court are also identified. The Comment concludes by highlighting the importance of the court and by noting that the benefits provided by the court are currently limited by the absence of funding from any source

    The Deleuzian Revolution: Ten Innovations in Difference and Repetition

    Get PDF
    Difference and Repetition might be said to have brought about a Deleuzian Revolution in philosophy comparable to Kant’s Copernican Revolution. Kant had denounced the three great terminal points of traditional metaphysics – self, world and God – as transcendent illusions, and Deleuze pushes Kant’s revolution to its limit by positing a transcendental field that excludes the coherence of the self, world and God in favour of an immanent and differential plane of impersonal individuations and pre-individual singularities. In the process, he introduces numerous conceptual innovations into philosophy: the becoming of concepts; a transformation of the form of the question; an insistence that philosophy must start in the middle; an attempt to think in terms of multiplicities; the development of a new logic and a new metaphysics based on a concept of difference; a new conception of space as intensive rather than extensive; a conception of time as a pure and empty form; and an understanding of philosophy as a system in heterogenesis – that is, a system that entails a perpetual genesis of the heterogeneous, an incessant production of the new. Keywords: concepts, becoming, multiplicity, singularity, the middle [au milieu], difference, intensity, time, system, the ne
