State-copying and Recomputation in Parallel Constraint Programming with Global Constraints

In this paper we discuss parallelization and distribution of problems modeled in a constraint programming (CP) framework. We focus on parallelization of depth-first search methods, since search is the most time-consuming task in CP. The current hardware development is moving towards multi-core processors and the cost of building distributed systems is shrinking. Hence, parallelization and distribu

Carsim: A System to Visualize Written Road Accident Reports as Animated 3D Scenes

This paper describes a system to create animated 3D scenes of car accidents from reports written in Swedish. The system has been developed using news reports of varying size and complexity. The text-to-scene conversion process consists of two stages. An information extraction module creates a structured representation of the accident and a visual simulator generates and animates the scene. We firs

Study of alternative strategies to the task clarification activity of the market-pull product development process model

A very large majority of the current product development process models put forward in textbooks present a homogenous structure, what Ulrich & Eppinger [1] call the market-pull model, presented as a generic one, while other possible product development process models are merely seen as variants. This paper focuses on the task clarification and derived activities (mainly the systematic search f

Unshrouded rotor tip clearance effects in expander cycle turbines

Steady flow in axial one-stage turbines is assessed numerically and experimentally. The simulations are performed on coarse meshes using a standard numerical approach (3D, steady state, kε-turbulence model, wall function at solid boundaries). In order to allow for conclusions drawn from these rapid numerical studies, the approach was compared with an explicit LDA (Laser Doppler anemometry) mapping

Neural network prediction of polyproline type II secondary structures

This study considers detection of polyproline type II secondary structures from protein sequences. This difficult problem was handled with multilayer perceptron neural networks, which were found to be useful for such bioinformatics studies. Polyproline II secondary structures have not previously been tried to be predicted from sequences.

The long-term consequence of anterior cruciate ligament and meniscus injuries: osteoarthritis.

The objectives of this study are to review the long-term consequences of injuries to the anterior cruciate ligament and menisci, the pathogenic mechanisms, and the causes. of the considerable variability in outcome. Injuries of the anterior cruciate ligament and menisci are common in both athletes and the general population. At 10 to 20 years after the diagnosis, on average, 50% of those with a di

Distinct and overlapping patterns of cytokine regulation of thymic and bone marrow-derived NK cell development.

Although bone marrow (BM) represents the main site for postnatal NK cell development, recently a distinct thymic-dependent NK cell pathway was identified. These studies were designed to investigate the role of cytokines in regulation of thymic NK cells and to compare with established regulatory pathways of BM-dependent NK cell compartment. The common cytokine receptor gamma-chain (Il2rg) essential

Chimney grafts preserve visceral flow and allow safe stenting of juxtarenal aortic occlusion.

OBJECTIVE: Chimney grafts have proven useful for urgent endovascular repair of juxtarenal aortic aneurysms. Stenting of juxtarenal aortic occlusive disease is not routinely advocated due to the risk of visceral artery obstruction. We report on the potential applicability of chimney grafts in 10 patients with juxtarenal aortic stenosis or occlusion. To our best knowledge, chimney grafts have not be

“The green political consumer of food: A critical analysis of the research and policies”

Abstract in UndeterminedThis paper reviews the current literature on political and ethical consumers, and relates it to the topic of sustainable food consumption. A first aim is to problematise a somewhat simplistic view of the political and ethical consumer found in the literature. The paper sheds light on some of the dilemmas that confront green political consumers. We indicate that most existin

Minimum-energy broadcasting in wireless networks in the d-dimensional Euclidean space (the alpha

We consider the problem of minimizing the total energy assigned to nodes of wireless network so that broadcasting from the source node to all other nodes is possible. This problem has been extensively studied especially under the assumption that the nodes correspond to points in the Euclidean two- or three-dimensional space and the broadcast range of a node is proportional to at most the α root of

Vanished History : The Holocaust in Czech and Slovak Historical Culture

Bohemia and Moravia, today part of the Czech Republic, was the first territory with a majority of non-German speakers occupied by Hitler’s Third Reich on the eve of the World War II. Tens of thousands of Jewish inhabitants in the so called Protectorate of Bohemia and Moravia soon felt the tragic consequences of Nazi racial politics. Not all Czechs, however, remained passive bystanders during the g

Strategic growth of industrial design consultancy: a study of changes in ID consultancy in a post-industrial society I

Based on a study of Swedish and Finnish industrial design consultancies (IDCs) we discuss how changes in industry have affected id-consultancies cope with growth, organizational and management issues. The traditional industrial designer worked in a small consultancy mainly with clients focusing on mass-produced products. The clients were basically domestic even if they operated worldwide. Investme

Multicast routing for ad hoc networks with a quality of service scheme for session efficiency

The conceptual shift in expectations of wireless users from voice towards multimedia, from availability towards acceptable quality, and from stand-alone towards group-oriented computing has a big impact on the needs of today's networks in terms of mobility, quality of service (QoS) support, and multicasting. Ad hoc networks can provide users with these features. However, it is necessary to develop

Muscle Cooling and Performance: A Review

Objectives: Skeletal muscle performance is determined by muscle temperature. This paperpresents a review of the research literature to contribute to a better understanding of thephysiological mechanisms of muscle fatigue and performance in cold exposure and in repetitiveor sustained physical exertion in terms of isometric maximal force production,electromyographic activities, and gait ground react

Occupational value and relationships to meaning and health: Elaborations of the ValMO-model.

Abstract This study investigates the theoretical assumption of the Value and Meaning in Occupations model. The aim was to explore the relationship between occupational value, perceived meaning, and subjective health in a sample of individuals of working age, 50 men and 250 women. Frequency of experienced values in occupations was assessed through the Occupational Value instrument with pre-defined
