    An optimal control approach to pilot/vehicle analysis and Neal-Smith criteria

    Get PDF
    The approach of Neal and Smith was merged with the advances in pilot modeling by means of optimal control techniques. While confirming the findings of Neal and Smith, a methodology that explicitly includes the pilot's objective in attitude tracking was developed. More importantly, the method yields the required system bandwidth along with a better pilot model directly applicable to closed-loop analysis of systems in any order

    Arkansas Small-Grain Cultivar Performance Tests 2004-2005

    Get PDF
    Small-grain cultivar performance tests are conducted each year in Arkansas by the Arkansas Agricultural Experiment Station, Department of Crop, Soil and Environmental Sciences. The tests provide information to companies developing cultivars and/or marketing seed within the state and aid the Arkansas Cooperative Extension Service in formulating cultivar recommendations for smallgrain producers

    The Optimal Single Copy Measurement for the Hidden Subgroup Problem

    Full text link
    The optimization of measurements for the state distinction problem has recently been applied to the theory of quantum algorithms with considerable successes, including efficient new quantum algorithms for the non-abelian hidden subgroup problem. Previous work has identified the optimal single copy measurement for the hidden subgroup problem over abelian groups as well as for the non-abelian problem in the setting where the subgroups are restricted to be all conjugate to each other. Here we describe the optimal single copy measurement for the hidden subgroup problem when all of the subgroups of the group are given with equal a priori probability. The optimal measurement is seen to be a hybrid of the two previously discovered single copy optimal measurements for the hidden subgroup problem.Comment: 8 pages. Error in main proof fixe

    Alfabetizaciones apropiadas: O paradoxo das alfabetizações críticas, políticas e metodologias de uma era pós-verdad

    Since 2016, there has been a proliferation of discourse around what has come to be called “post-truth.” Much of this discourse references critical literacies as a proposed means by which to disrupt post-truth across educational policy, pedagogy, and methodology. In this paper, I highlight the paradoxical degree of overlap between post-truth and the critical literacy approaches espoused to combat it. Left underexplored, these appropriated literacies may do more to embolden than to dismantle post-truth. I first typify three “first wave” responses to post-truth, exploring the affordances and limitations of each. I then provide recommendations for augmenting these responses through a renewed emphasis on power, domination, and liberation in critical literacies as a response to post-truth.Desde 2016, ha habido una proliferación de discursos sobre lo que se ha denominado “posverdad.” Gran parte de este discurso hace referencia a las alfabetizaciones críticas como un medio propuesto para interrumpir la posverdad a través de la política educativa, la pedagogía y metodología. En este artículo, resalto el grado paradójico de superposición entre los enfoques de alfabetización posverdad y crítica propugnados para combatirla. Si se deja de explorar, estas alfabetizaciones apropiadas pueden hacer más para envalentonar que desmantelar la posverdad. Primero tipifico tres respuestas de “primera movimiento” a lapos verdad, explorando las posibilidades y limitaciones de cada una. Luego ofrezco recomendaciones para aumentar estas respuestas a través de un énfasis renovado en el poder, la dominación y la liberación en las alfabetizaciones críticas como respuesta a la posverdad.Desde 2016, tem havido uma proliferação de discursos sobre o que se denominou “pós-verdad.” A parte de seu discurso tem como referência as palavras-chave como uma proposta de ensino para o ensino pós-graduado a través da política educacional, pedagogia e metodologia. Este artigo é sobre o paradigma da superposição entre as enfoques de alfabetização pós-verão e crítica propugnados para combatirla. Si se importa de explorar, estas alfabetizaciones apropiá-las são mais importantes para envalentar que desmantelam a tarde posterior. Primero tipifico tres respuestas de “primera movimento” a la verdad posterior, explorando as posibilidades e limitaciones de cada una. O primeiro a oferecer recomendações para aumentar as respostas a um novo poder sobre o poder, a dominação e a libertação nas alfabetizações como uma resposta pós-verdad

    Research on graphite reinforced glass matrix composites

    Get PDF
    A composite that can be used at temperatures up to 875 K with mechanical properties equal or superior to graphite fiber reinforced epoxy composites is presented. The composite system consist of graphite fiber, uniaxially or biaxially, reinforced borosilicate glass. The mechanical and thermal properties of such a graphite fiber reinforced glass composite are described, and the system is shown to offer promise as a high performance structural material. Specific properties that were measured were: a modified borosilicate glass uniaxially reinforced by Hercules HMS graphite fiber has a three-point flexural strength of 1030 MPa, a four-point flexural strength of 964 MPa, an elastic modulus of 199 GPa and a failure strain of 0.0052. The preparation and properties of similar composites with Hercules HTS, Celanese DG-102, Thornel 300 and Thornel Pitch graphite fibers are also described

    PREFERENCES OF MID-ATLANTIC SEAFOOD BUYERS TOWARD FARM-RAISED HYBRID STRIPED BASS

    A market survey of three mid-Atlantic food-fish market levels was conducted to provide information on finfish buyers' market characteristics, finfish attribute preferences, and buyers' attitudes toward farm-raised hybrid striped bass. Results showed that most firms are located in the suburban areas, and they purchased their fish from producers and wholesalers. Quality was rated as the most important finfish attribute; and, aside from restaurants, buyers are generally familiar with hybrid striped bass and indicated that it could easily be substituted for wild striped bass. Most buyers were either not sure or feel hybrid striped bass could not substitute for other fish species although they all expressed a willingness to offer farm-raised hybrid striped bass. Finally, the possibility of fish farmers selling directly to all market levels has great potential if the fish size is around two to three pounds and the form is whole for the wholesaler and retailer and fillet for the restaurants.Consumer/Household Economics,
