Dagens grafikkort är uppbyggda av kraftfulla multiprocessorer som gör dom ypperliga för att hantera parallelliserbara problem som skulle ta lång tid att utföra på en vanlig processor, så som exempelvis level-of-detail eller raytracing.Denna rapport presenterar en parallelliserbar level-of-detail algoritm för terränghöjdkartor samt implementerar denna för användning på grafikkort användande Nvidias CUDA API. Algoritmen delar upp den totala höjdkartan i sektioner som ytterligare delas upp i mindre block som beräknas parallellt på grafikkortet. Algoritmen räknar ut vertexpositioner, normaler och texturkoordinater för vardera block och skickar datan till applikationen som skapar vertex och indexbuffertar och renderar sektionerna. Implementationens prestanda och förmåga att reducera trianglar analyseras med två olika sorters culling-metoder; en metod som gallrar trianglar på sektionsnivå och en metod som gallrar på blocknivå.Resultaten visar att det är mycket fördelaktigt att låta grafikkortet hantera level-of-detail beräkningar på detta vis även om minneskopiering över grafikkortsbussen är ett problem, då det tar upp ungefär åttiofem procent av den totala tiden för att hantera en sektion. Beräkningarna i sig tar väldigt lite tid och det finns gott om utrymme för utveckling för att uppnå en så bra fördelningen av trianglar över terrängområdet som möjligt..

The purpose of this thesis is to evaluate the retrieval effectiveness on the European Unions official website EUROPA, depending on which language is used to formulate the search question. Our main concern were if you get access to the same information depending on which language is used to search information The European Union has so far eleven official languages, and with the forthcoming expansion with negotiations with thirteen new countries to affiliate to the union by May 1:st 2004, the official languages will be even more. We have made a comparison between Swedish and English, using 29 different topics from which we formulated 2x29 queries. The topics used were found at the Swedish Governments FAQ about the European Union, EUsvar. We wanted the topics to be as authentic as possible to avoid bias.

The United States use of Unmanned Combat Aerial Vehicles (UCAV) or drones for targeted killings of terrorists has been on the rise in recent years and the method has become the core element of president Obamas strategy in the war against terror. This study examines the deterrent effect of targeted killings on terrorism using UCAV/drones as a method of counterterrorism. Building on the literature on counterterrorism, UCAV, targeted killings, deterrence theory and statistics on terrorism the study provides a case study of the CIA drone operations in Pakistan between the years 2004-2010. The goal has been to analyze drone operations and the extent of terrorism from the beginning of the drone campaign until 2010. This as a means of identifying possible trends in terrorism activity due to the occurrence of drone strikes.

The aim of this study was to examine how adoptive parents related to parenting and how they related to their children?s biological origin. Issues that were used were how adoptive parents described their own parenting, how they described their own thoughts about their children eventually wanting to search their biological origin and how adoptive parents described the child´s country of birth attitudes towards adoptees wishes to search their biological origin. The method used was qualitative research interviews. The theory that was used for analyzing the collected data was attachment theory.

There is consensus in research, policy, business and many other areas around the benefits of creativity. Previous research shows that creativity is only spurred under certain conditions. Usually creativity is not associated with concepts such as control, deadline or cost effectiveness. Companies, by contrast, have the need for control and management of their operations, which implies that the two processes can be difficult to reconcile. A company that wants a high creativity while maintaining control and management is forced into a series of organizational compromises.

This paper describes the development of a simulation model for the ambulance flow in the Västra Götalands-region of Sweden, and an analysis tool for the output of the simulation model. The aim of the simulation model was to be able to evaluate the outcome from changes in the ambulance operations, such as a reorganization of ambulances or an increase in intensity of the ambulance calls. This evaluation is meant to serve as decision support for the strategic planning of the ambulance operations. The analysis tool was developed to visualize the abundant geographical data produced by the simulation model in a meaningful way. The simulation model was validated against historical data which showed that the dispatch time for the highest prioritized ambulance calls corresponds well with historical data.

Swedish agriculture has gone through big changes in the latest 60 years. The farm sizes have increased, which has led to raised tractor and machinery sizes and therefore increasing problems with soil compaction. A method to reduce these problems is to implement controlled traffic farming, CTF. All field operations are then concentrated to specific tracks by using GPS guidance. The aim of this work was to study how the tillage regime, with or without CTF, affects the soil, with the main focus on macroporosity. In Säby close to Uppsala, and Alnarp close to Malmö, randomized block trials has been carried out, and the data has mainly been taken from these trials.

But how can this be achieved? Are there step-by-step procedures? What´s included in the management process of IT-incidents? Is the size of the organization relevant to which model is to be chosen? Can the work of the writers of this essay result in a recommendation of a specific model for IT-incident management? These questions lead to the following essay question; How are IT-incidents managed?Purpose: The purpose of this thesis is to describe and discuss how IT incidents can be managed.Method: The writers of this essay have performed a case study at ICA, a Swedish food retail company. Eleven interviews with nine different persons have been carried out. The interviews are analyzed in the chapter called Resultat och analys.Conclusion: Our conclusion is that there are both similarities and differences in Dept.

This study aims to examine how performance management is compatible with the operations at Sida, Sweden?s International Development Cooperation Agency, by performing interviews with representatives from Sida. The public sector is facing increased demands on accounting, which has emerged as an institutionalized social norm in society. The nature of Sida?s operations, however, proves to be highly complex, rendering results based management difficult to implement.

Swedish forests are dominated by just two conifer species Norway spruce and Scotch pine. They are not able to achieve the highest possible production or fulfill industry demands for raw materials. The introduction of exotic conifers can potentially meet these shortcomings and present a relevant solution. This study was conducted in a block experiment with ten blocks planted in 1987 by SCA in North Sweden. The objective of the block experiment was to study if Black spruce is an appropriate alternative to Lodgepole pine, Norway spruce and Scotch pine on different site classes.

Computerized methods for searching pictures are becoming more common. With these it ispossible to make powerful search requests using a combination of terms and search oncomprehensive descriptions of the pictures. The descriptions can encompass various aspectsof the content and allow different interpretations and levels of detail.This essay is about how you can examine and describe the content of a picture from manypoints of view. We have tried to identify differences in searching behaviour, and studiedsome methods for indexing of pictures. Our concepts are taken from the philosophy of artand from theories about the meaning of languages.In the future perhaps libraries can make pictures and illustrations in books available to thepublic, in a sophisticated system, for the purpose of providing visual documentation forstudy, research or other kinds of exploitation..

Title: Locally Integrated Groups ? A special education alternative Author: Jennie Arvidsson Type of essay: Exam essay, second level (15 credits) Supervisor: Barbro Bruce, Examiner: Lisbeth Ohlsson Program: Special Education Program at Malmö Högskola, Sweden Date: 2012-01-12 Present study is an attempt to describe how staff perceive their working operations in seven locally integrated groups, for pupils in special educational needs. By submitting a questionnaire to all professions within the groups I have tried to find similarities and differences in their statements from both structured and unstructured questions. The study is an attempt to contribute knowledge about how these groups can be understood and developed, based on a special education perspective, systems theory and sense of coherence (KASAM). The results shows that there is a consensus among the majority of staff opinions of the systems? opportunities as well as dilemmas.

This essay is divided in several different parts, but all are tied up together by a fact that we want to increase productivity. We hope to do that by programming the PLC and to reach this with a better security for the person how are going to handle the cutting machine under it?s cutting process. We should as well look for some other ways to come up with better instructions and way to work and handle yourself during work. This programming is done in GRAPH7.

The purpose with this thesis is to research what function the National Library Catalogue of Sweden (LIBRIS) has as an information resource for Chinese language material. How is LIBRIS used as an information resource seen from the point of view of a users specific language need. This will be exemplified through an empirical survey of three user groups with different prerequisites concerning their knowledge in Chinese. Group A were beginners and had studied Chinese for one year. Group B were advanced students who were studying their third year of Chinese.
