Abstract CORDIC (Coordinate Rotation Digital Computer) is an iterative algorithm for the calculation of a two-dimensional vector in circular, linear or hyperbolic coordinate systems. This paper presents a survey of known CORDIC algorithms and architectures for the rotation and vectoring mode in the circular cordinate system. In addition an implementation of the differential CORDIC algorithm in VHDL has been done. The implementation is designed to keep the fast timing and throughput characteristic known for on-line redundant arithmetic..

Hur läroböcker är utformade och vilket innehåll de har är inte en slump, utan ett resultat av åratal av forskning och ett samhälle i konstant förändring. Idag tar vi det som en självklarhet att ett stort kapitel i biologiundervisningen, såväl på högstadiet som i gymnasiet, tas upp av evolutionen, det vill säga läran om livets utveckling. Så har det inte alltid varit.Denna undersökning ämnar till att se om det finns ett samband mellan sekulariseringen av skolan och hur ämnet evolution har formats i biologiläroböckerna för högstadiet och gymnasiet. En textanalys har gjorts av 20 läroböcker från olika stadier och tidsperioder, resultaten har sammanställts och diskuterats.Sammanfattningsvis kan konstateras att biologiböckernas innehåll har förändrats i takt med dels sekulariseringen av den svenska skolan och dels olika skolreformer som gjorts under 1900-talet. Till detta kan vi addera de framsteg som naturvetenskapen gjort från andra halvan av 1800-talet fram till idag.

The purpose of this study is to find out why the EU has not yet implemented the EuropeanCivil Peace Corps (ECPC), which the EU Parliament took a resolution about in 1999. Themore specific questions posed are whether the concept of ECPC has been redefined, whetherthe issue of ECPC has been prevented from coming up for discussion and decision-making,and what this has meant for the non-implementation. Steven Lukes' theory about the threedimensions of power is used in combination with a discourse analysis method. The materialused is documents from the EU Parliament's decisions and debate about ECPC, and ECPCfeasibility studies. In the analysis I find one "law and order"-discourse and one "peaceknowledge"-discourse.

Problem discussion: Long-term supplier relationships have become more common. Hence, supplier evaluation is a critical activity for many companies. However, making a relevant supplier evaluation is time consuming. Therefore, it is important to decide which of the suppliers to put an extra effort on. Should all suppliers be evaluated in the same way? Previous, focus has been on purchasing of direct material.

Good business relations can contribute to the success of IT-outsourcing, and create new business opportunities. Despite a sharply increasing trend to outsource IT-operations there is a high degree of failures related. The cause may be that some important factors have not been taken into account. The purpose is to investigate elationships within IT-outsourcing and test if specific factors identified by previous research are being concerned in IT-outsourcing relationships and also to investigate the view IT-outsourcing customers and suppliers have on business. Research shows that business relationships are widespread throughout companies. It demonstrated that a small number of business relationships can have a major impact on a company's financial performance and may create stability. Business relationships can be divided into an arm's length relationships and strategic alliances depending on the degree of involvement.

The aim of this thesis is to assess the strategic importance of Central Asia as a whole and interests of great powers in the region in particular within the theoretical framework chosen. The work shows Central Asia as an area of the New Great Game, analogue of the original Great Game which was played out between the British Empire and Tsarist Russia in XIX century. The parallels between the original Great Game and the New Great Game are drawn in order to understand the scope and the true intentions of the players of the latter one. Also, the security issues in the contemporary Central Asia are explored and analyzed to provide with the background for future predictions. Furthermore, the indirect purpose of the thesis is to examine whether the international system has changed from that of two centuries ago by comparing the structure of the international systems at the time of two Games.

This study was carried out in Ronneby municipality during May 2006. I chose to compare three senior schools with regards to the implementation of objective orientated directives based on the teachers understanding of the task, motivation, resources allocated and their significance for the disparity between boys? and girls? grades.I carried out nine in-depth interviews: three at each senior school. From the interviews it emerged that teachers perceive objectives differently from parents and students. Teachers claim that they understand the directives but say that they lack the resources.

When a decision is to be made on what long term strategic forest management plan to use, consideration must often be taken to multiple objectives. Such decisions are very complex and a promising approach to handle them is by Multiple Criteria Decision Analyses (MCDA). The study is based on the problem that the MCDA that have been implemented into forest management planning have only had capacity to compare and evaluate a limited number of management plans; which means that there is a risk the most suitable plan is missed. The aim with this study was to test the applicability of combining the MCDA tools: the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and the Analytic Hierarchy Process (AHP) for including consideration to multi-objectives into strategic forest management planning. The study was based on the process of creating and selecting a management plan, using Heureka PlanWise, suitable for all the major objectives found in the forest holdings of a municipality in northern Sweden.

The aim of the study was to examine prerequisites for the changes that are taking place within working with Intimate Partner Violence in Va?stra Hisingen (a municipal district in Gothenburg, Sweden). My research questions concerned incentives for the new features, their practical consequences and prerequisites for implementation. The study has been performed by three focus group interviews with different parts of the organization represented. The work material has then been analyzed using Implementation Theory, Human Service Organization Theory and theories on breaking up.

The study addresses the field of design as a profession and examines the views on strategic management in a design project among nine selected graphic designers. The graphic designers who participate in the study are permanently employed at design companies in Stockholm. The study has a qualitative approach and the method is based on face-to-face interviews. We have chosen to examine this subject due to the opinion among professionals that strategic management in the design industry has increased during the last decades. There is a belief that strategic management in some cases are used too extensively as a way for design companies to make more money.

Detta arbete utgör specifikation, implementation och utvärdering av ett läroverktyg sett till hur man säkerställer att en ensam utvecklare lyckas i varje enskild problemdomän. Detta nås genom en metodik för kravinsamling och specificering grundad i Co-Creation, designmönster och kodstrukturering som stöd i själva utvecklingen samt agil utvecklingsmetod sett ur perspektivet av en ensam utvecklare..

Lean has been studied intensely since the 1980s and it has been tested and successfully implemented in a wide variety of businesses. This thesis aims to examine the potential effects of a Lean implementation on meeting efficiency, a topic that has gotten little attention in the research community. First, a number of meeting problems are introduced, as they are perceived from the company that is the subject of the study. Second, the potential of introducing Lean in a meeting process is evaluated using the Lean Thinking principles. Third, the wastes that are generated from the meeting problems are identified.

The aim of this paper is to explain and compare non-compliance of two EU-directives, ?the quality of bathing water? and ?the working time directive?. This study answers the questions: Why didn?t Sweden implement the directive on bathing water quality and the working time directive correctly? Are the reasons for non-compliance the same or different in the two cases? The paper is designed as a case study and with an explanatory attempt we explain why the two directives weren?t implemented correctly in Sweden. The theoretical approach is based on both general- and EU-specific implementation theories.

The development in electronics increases the demand for good design methods and design tools in the field of electrical engeneering. To improve their design methods Ericsson Microwave Systems AB is interested in using computer tools to create a link between the specification and the implementation of a digital system in a FPGA. Xilinx System Generator for DSP is a tool for implementing a model of a digital signalprocessing algorithm in a Xilinx FPGA. To evaluate Xilinx System Generator two testcases has been designed. The testcases are selected to represent the FPGA designs made at Ericsson Microwave Systems.

The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.
