21. DOF = Degrees of Freedom E = Atmospheric Entry Time - Eric M. Queen; Jill L. Prince; Prasun N. Desai
A multi-body flight simulation for the Phoenix Mars Lander has been developed that includes high fidelity six degree-of-freedom rigid-body models for the parachute and lander system. The simulation provides attitude and rate history predictions of all bodies throughout the flight, as well as loads on each of the connecting lines. In so doing, a realistic behavior of the descending parachute/lander system dynamics can be simulated that allows assessment of the Phoenix descent performance and identification of potential sensitivities for landing. This simulation provides a complete end-to-end capability of modeling the entire entry, descent, and landing sequence for the mission. Time...

22. PROBABILITY-BASED INVERSE MODELING ALGORITHM FOR INDOOR POLLUTANT SOURCE TRACKING - Xiang Liu; Zhiqiang Zhai
Building indoor environment quality (IEQ) has received growing attentions lately because of the extended time people spend indoors and the increasing reports of health problems related to poor indoor environments. Recent alarms to potential terrorist attacks with airborne chemical and biological agents (CBA) have further highlighted the research needs on building vulnerability and protection. To maintain a healthful and safe indoor environment, it is crucial to identifying contaminant source locations, strengths and release histories. Accurate and prompt identification of contaminant sources ensures that the contaminant sources can be quickly removed and contaminated spaces can be effectively isolated and cleaned. This...

El objetivo principal del trabajo consiste en la formulación y estructuración del concepto de operador de historial de salud electrónico I-HSE, para llevarlo a un esquema de oferta de servicios tecnológicos. El proyecto incluye tres aspectos dentro de su alcance: estudio de factibilidad, el diseño del servicio y el plan de implementación. La solución propuesta resuelve la ubicuidad de la información de cada paciente, requerida para su atención, a través de un servicio de intermediación integral que incluye un diseño de interoperabilidad organizado con bases de datos federativas y estándares de intercambio de información en salud. Todo esto enmarcado en...

24. with simplified relations between the state of deformation and their histories. In terms of the anisotropy - Myoung-gyu Lee A; R. H. Wagoner B; J. K. Lee C; K. Chung D; H. Y. Kim E
Magnesium alloy sheets have been extending their field of applications to automotive and elec-tronic industries taking advantage of their excellent light weight property. In addition to well-known lower formability, magnesium alloys have unique mechanical properties which have not been thor-oughly studied: high in-plane anisotropy/asymmetry of yield stress and hardening response. The rea-son of the unusual mechanical behavior of magnesium alloys has been understood by the limited symmetry crystal structure of HCP metals and thus by deformation twinning. In this paper, the phenomenological continuum plasticity models considering the unusual plastic behavior of magne-sium alloy sheet were developed for a finite element...

25. Knowledge Management and the Semantic Web: From Scenario to Technology
In 2001, Tim Berners-Lee, James Hendler, and Ora Lassila wrote a seminal article inwhich they envisioned the Semantic Web.1 The article’s general tenor, and particu-larly their scenario demonstrating how the Semantic Web might be used, was directed toward identifying and using services on the Web. The pursuit of this vision continues. This article describes a complementary vision— a vision of the Semantic Web as a knowledge man-agement environment. All knowledge workers—whether they’re histori-ans, physicists, financial advisors, or simply indi-viduals researching a topic for personal reasons— share certain characteristic activities. One of the chief among these activities is the need to...

27. Resource Management under Traditional Tenure: The Political Ecology of a Contemporary Problem, New Georgia Islands, Solomon Islands - John Mckinnon
High rates of population growth, increased competition for access to resources, growing strains on traditional tenure systems and the wish to improve standards of living combine to threaten the tenor of everyday life. The need to maintain the environment, a reliable supply offood for domestic consump tion and a continuing flow of cash income makes it necessary to plan for a better future. Largely because people cannot agree on how to resolve tenure problems their ability to manage resources is limited. Oral rules and histories which provide the basis of tenurial rights to land and reefs are often confused and...

28. North atlantic fisheries in change: From Organic Associations to Cybernetic Organizations Jahn Petter Johnsen - Barbara Neis
Abstract During the 1990s radical changes took place in marine ecosystems, fisheries and fishing communities around the North Atlantic. Social-ecological restructuring involving interactive changes in marine ecosystems, harvest tech-nologies, fisheries science, management practices and goals, fishing households and communities and markets radically transformed fisheries associations. This article draws on insights from multiple sources, including a series of career his-tory and other semi-structured interviews with fishers from Newfoundland and Labrador and Norway. These insights are presented in the form of career histories of two fishers, one from North Norway and one from Labrador on Canada’s east coast. These career histories are...

29. Linguistics of the Tibeto-Burman Area Volume 16:1 — Spring 1993 Rhythm and Vocalic Drift in Munda and Mon-Khmer - Patricia Donegan
Opposite rhythmic principles are responsible for the opposite typological tendencies of the Southeast Asian (Mon-Khmer) and Indie (Munda) branches of the Austroasiatic language family. The phonological divergence between Mon-Khmer and Munda is largely the result of stress-timing in Mon-Khmer and mora-timing in Munda; their vowel phonologies, especially, show how the two branches represent opposite phonological types. Mon-Khmer and Munda differ sharply in their vowel phoneme inventories, and also in the kinds of phonological processes that have applied throughout their histories. The phoneme inventories and process types of Mon-Khmer and Munda parallel those of other stress- and mora-timed languages, respectively, and...

30. Epilepsy Case Studies - Edward Faught Mda B
Seizures are the second most common neurologic condition, after headache. All physicians encounter patients who have seizures and may be called on to treat them. Therefore, a basic knowledge of seizure types, causes, and treatment strategies is useful. It also is helpful to be able to recognize some of the common epilepsy syndromes. This article reviews the definitions and terminology of seizures and epilepsy syndromes and uses case histories to describe typical scenarios likely to be encountered by primary care physicians and neurologists. Definitions A seizure is a brief disturbance of cerebral function, lasting from seconds to a few minutes,...

31. Protagonistas de la historia vasca (1923-1950)
Del 21 al 31 de mayo de 1984 se celebraron en los salones de la Diputación Foral de Gipuzkoa, organizado por Eusko Ikaskuntza unas mesas abiertas en las que participaron organizaciones sindicales y fuerzas políticas con protagonismo ideológico durante el período 1923-1950. Los protagonisas repasaron hechos y acontecimientos de la reciente historia vasca, desde la Dictadura de Primo de Rivera hasta la Guerra Civil y la Postguerra (1950)

39. La chiesa extraurbana di Tuscolo. Prime ipotesi di identificazione. - Beolchini, Valeria
Gli scavi condotti a partire dal 1994 dall 'Escuela Española de Historia y Argueolgía en Roma-CSIC nell'area dell'antico e abbandonato sito di Tuscolo hanno restituito consistenti tracce di fasi insediative databili ai secoli centrali del medioevo, in misura superiore ad ogni più rosea previsione. All 'inizio delle ricerche gli archeologi nutrivano infatti ben poche speranze di poter ancora rinvenire in situ resti significativi dell'abitato di XI-XII secolo, a causa delle testimonianze fornite in tal senso sia dalle fonti storiche coeve, sia dai diari di scavo relativi alle campagne archeologiche condotte al Tuscolo a partire dal XVIII secolo.
