Selected AbstractsThe generation of hexahedral meshes for assembly geometry: survey and progress,INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING, Issue 12 2001Timothy J. Tautges Abstract The finite element method is being used today to model component assemblies in a wide variety of application areas, including structural mechanics, fluid simulations, and others. Generating hexahedral meshes for these assemblies usually requires the use of geometry decomposition, with different meshing algorithms applied to different regions. While the primary motivation for this approach remains the lack of an automatic, reliable all-hexahedral meshing algorithm, requirements in mesh quality and mesh configuration for typical analyses are also factors. For these reasons, this approach is also sometimes required when producing other types of unstructured meshes. This paper will review progress to date in automating many parts of the hex meshing process, which has halved the time to produce all-hex meshes for large assemblies. Particular issues which have been exposed due to this progress will also be discussed, along with their applicability to the general unstructured meshing problem.

Southern, Scholastic Humanism and the Unification of Europe, Vol.JOURNAL OF RELIGIOUS HISTORY, Issue 3 2002I: Foundations Richard Southern's most recent book proposes an interpretation of the intellectual life of twelfth,century Europe that deserves both close attention and critical scrutiny. Particular issues questioned in this review are the dominant centrality of the "scholastic enterprise," Southern's idiosyncratic definition of "humanism," and his prolongation of the twelfth,century renaissance through most of the thirteenth. It is argued that Southern's interpretation has led to the undervaluation of regions of western Europe such as Germany, and of non,scholastic communities such as Benedictine monasticism. [source] Kinematics, Dynamics, Biomechanics: Evolution of Autonomy in Game AnimationCOMPUTER GRAPHICS FORUM, Issue 3 2005Steve Collins The believeable portrayal of character performances is critical in engaging the immersed player in interactive entertainment. The story, the emotion and the relationship between the player and the world they are interacting within are hugely dependent on how appropriately the world's characters look, move and behave. We're concerned here with the character's motion; with next generation game consoles like Xbox360TM and Playstation®3 the graphical representation of characters will take a major step forward which places even more emphasis on the motion of the character. The behavior of the character is driven by story and design which are adapted to game context by the game's AI system. The motion of the characters populating the game's world, however, is evolving to an interesting blend of kinematics, dynamics, biomechanics and AI drivenmotion planning. Our goal here is to present the technologies involved in creating what are essentially character automata, emotionless and largely brainless character shells that nevertheless exhibit enough "behavior" to move as directed while adapting to the environment through sensing and actuating responses. This abstracts the complexities of low level motion control, dynamics, collision detection etc. and allows the game's artificial intelligence system to direct these characters at a higher level. While much research has already been conducted in this area and some great results have been published, we will present the particular issues that face game developers working on current and next generation consoles, and how these technologies may be integrated into game production pipelines so to facilitate the creation of character performances in games. The challenges posed by the limited memory and CPU bandwidth (though this is changing somewhat with next generation) and the challenges of integrating these solutions with current game design approaches leads to some interesting problems, some of which the industry has solutions for and some others which still remain largely unsolved. [source] A Late Neolithic vertebrate food web based on stable isotope analysesINTERNATIONAL JOURNAL OF OSTEOARCHAEOLOGY, Issue 4 2006C. Bösl Abstract Stable carbon and nitrogen isotope analyses of bone collagen, and stable carbon and oxygen isotope analyses of the bone's structural carbonate, were performed on 120 individuals representing 33 vertebrate species, including a single human bone find, collected from the Late Neolithic settlement at Pestenacker, Bavaria, Germany. We were thus capable of reconstructing a rather complex food web and could also address particular issues, such as whether humans influenced the diet of their domestic animals as opposed to their wild relatives, or whether humans perhaps had to compete over food with their domesticates. A rather unexpected result was that freshwater fish, which could be captured in the nearby river Lech, a major tributary of the Danube, contributed to the human diet only occasionally. As for mammals, it was also possible to recognise different trophic levels for birds and aquatic vertebrates, applying stable isotope analyses to both bone collagen and structural carbonate. In the case of fish, ,18O values at least revealed a physiological regularity in terms of temperature preference, besides diet. Conceivably, variability of ,18O in surface water as reflected, for example, by species that avoided human settlements, may help to characterise past ecosystems and to define site catchment exploited by Neolithic man in the course of food acquisition.

[source] Post-flood field investigations in upland catchments after major flash floods: proposal of a methodology and illustrationsJOURNAL OF FLOOD RISK MANAGEMENT, Issue 4 2008E. Gaume Abstract Post-event survey and investigation is one way to gain experience on natural hazards. The importance of the systematisation and standardisation of such investigations and re-analysis is progressively recognised in all the geophysical sciences as shown by the growing number of scientific papers and programs on the subject. But how to proceed in the case of a flash floods, what type of data should be collected for what type of analyses and to explore which particular issues? To give a first answer to these questions, a methodology for post-flash flood field investigations has been developed under the EC FLOODsite project and tested under the EC HYDRATE project. This paper presents shortly the principles of this methodology and illustrates its application for the study of two major flash floods that occurred in November 1999 and September 2002 in the South of France. [source] Nontraditional Students, Accelerated Programs, Grade Expectations, and Instructor EvaluationsJOURNAL OF LEGAL STUDIES EDUCATION, Issue 2 2006Pamela Gershuny This article is intended as both a cautionary tale and an encouraging guide for instructors who are beginning to teach in accelerated programs designed to attract nontraditional students. This article is based, in part, on classroom action research conducted through surveys, observations, exams, and assessments, in an introductory business law course taught in two different universities. Initially, this article seeks to define and examine the particular issues of the nontraditional student using demographic and anecdotal data gathered on nontraditional students at the University of Cincinnati and traditional students at Southeast Missouri State University. Special attention is given to the role of gender and role strain in nontraditional students. Role strain has three dimensions: (1) role conflict from simultaneous, incompatible demands; (2) role overload (insufficient time to meet all demands); and (3) role contagion or preoccupation with one role while performing another. The article also examines the relationship between grade expectations/grade inflation and instructor evaluations. [source] Addressing individual difficulties in reading: issues relating to Reading Recovery and Pause, Prompt, PraiseLITERACY, Issue 1 2004Janice Wearmouth Recently the DfES has issued guidance on ways to address the needs of students who experience difficulties in literacy through Wave Three provision in the National Literacy Strategy (DfES, 2002). This guidance raises the issue of what kind of programmes might be initiated in mainstream schools that will improve what is available generally for pupils who experience difficulties. The original Literacy Taskforce report (1997) named Reading Recovery (RR) as one programme suitable for this purpose. It is not the only programme with 'proven' efficacy, however. This article compares RR and another New Zealand-based programme, Pause, Prompt, Praise (PPP) with which it has a number of characteristics in common, in order to examine particular issues which are important to ensure that a particular programme can meet individual children's literacy needs and also have the potential for adoption by LEAs and schools in the current national curricular context. These issues are the underpinning rationales, assumptions about the reading process and questions of resources, ownership and control (Openshaw et al., 2002). [source] Negotiating Multiple Roles in the Field: Dilemmas of Being an Employee/ResearcherNORTH AMERICAN DIALOGUE (ELECTRONIC), Issue 2 2007Ashley Spalding More North Americanists must consider the implications of combining paid work with research since funding for our projects is not keeping up with the rising number of anthropologists conducting research in North America. In this article, I reflect on my own paid work and dissertation research in a divided "mixed income" neighborhood in Tampa, Florida. I negotiated multiple roles conducting research with both middle-class homeowners and low-income renters while working as an employee in one of the neighborhood's low-income apartment complexes. Paid work has advantages beyond making research financially possible. For instance, it enables greater access and insight into particular issues. It can also complicate a researcher's role/s in numerous ways, including how she is perceived by different members of the communities in which she works, and the practical and ethical issues that result. [source] Anesthetic issues in pediatric liver transplantationPEDIATRIC TRANSPLANTATION, Issue 5 2005Francine S. Yudkowitz Abstract:, Pediatric liver transplantations are becoming increasingly more common. Recent advances in the surgical and anesthetic management of these cases have greatly improved the survival rate. In order to successfully manage the anesthesia in these patients, one needs to have a thorough understanding of the pathophysiology of end-stage liver disease and the subsequent anesthetic implications. It is also necessary to appreciate the stages of the surgical procedure, as each stage presents different dilemmas to the anesthesiologist. This article will review the pathophysiology of liver failure in pediatric patients and outline the particular issues related to each stage of liver transplantation, allowing for the anticipation and management of the derangements that occur during surgery. [source] How Issues Become (Re)constructed in the Media: Discursive Practices in the AstraZeneca MergerBRITISH JOURNAL OF MANAGEMENT, Issue 2 2002B. Hellgren In this article, we put forward a novel way of exploring difference and contradiction in merging organizations. We examine how the media (re)constructs meanings in a major cross-border merger. Based on an analysis of press coverage, we attempt to specify and illustrate how particular issues are (re)constructed in media texts through interpretations of ,winning' and ,losing'. We also show how specific discourses are drawn on in this (re)construction. In the merger studied, discourse based on economic and financial rationale dominated the media coverage. Discourse promoting nationalistic sentiments, however, provided an alternative discursive frame to the dominant rationalistic discourse. We argue that the two basic discourses are enacted in three analytically distinct discursive practices in the media: factualizing, rationalizing and emotionalizing. We suggest that the ability of different actors such as top managers to make use of different discursive strategies and resources in promoting their ,versions of reality' in the media (or public discussion) is a crucial avenue for research in this area.
