The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their Implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

The Swedish government has set up 16 environmental goals for Sweden to achieve. One ofthem is ?Living forests?, which is the foundation for the ?National strategy for the formalprotection of forests?. The ?National strategy? puts the private forest owner at the centre ofattention in order to achieve the environmental goal ?Living forests?.

The history of books and libraries in the Philippines starts after the arrival of the Spaniards in 1521. During the Spanish era, most of the libraries were established through the religious orders to support their own religious mission. The Americans came in the beginning of the 20th century and have had a decisive influence on the education system and the development of libraries in the Philippines. For the analysis, I have used the models of Michael H. Harris and Magnus Torstensson in their studies of library development.

Gränssnitt finns överallt i vår vardag. Du finner dem i hemmet, i biblioteket, i affären, på tågstationen och till och med i din ficka. Hur kan utvecklingen av ett gränssnitt se ut och vad kan göras för att effektivisera utvecklingen? Ett gränssnitt kan alltid utvecklas och bli bättre. En gräns måste emellertid sättas för när gränssnittet är redo att komma ut på marknaden.

Syftet med studien var att identifiera de faktorer i litteraturen som kan bidra till ökad följsamhet och som kan underlätta implementeringen vid tillämpningen av fallförebyggande träningsinterventioner som genomförs i hemmet.

Totalt inkluderades 16 studier.

The explosion of new digital media puts pressure for developments within copyright law both in Sweden and internationally. These developments are taking place on two different international areas: (1) WIPO which is a part of the UN family and (2) the EU where a new directive on copyright law is being prepared and probably implemented during 2001. The aim of this thesis is twofold: (1) to study which considerations libraries must make when handling the new digital media both under today's copyright laws and under those which are being developed internationally. (2) What will be the consequences, for Swedish libraries, if the new EU-directive on copyright law is implemented in Sweden? By analysing current copyright laws, international treaties and the proposal for a new EU-directive as well as the national debate the thesis brings attention to a number of central issues for libraries.

The purpose of this thesis is to examine and analyze why, in the case of Afghanistan, the government chose to establish a highly centralized political system, when from a democratic standpoint a less centralized system would be preferable.The time period that is examined span from 2001 when the so-called Bonn-Accord was signed, to the parliamentary elections held in 2005, a period often referred to as the Bonn-process.The theoretical framework examines both the complex relations between federalism and democracy, as well as the relation between federalism and the role of existent ethnic minorities. The theoretical framework is then used in order to explain why it would be problematic to create a federal system in Afghanistan under the present circumstances.The conclusions that can be drawn are the following: In case of the republic Afghanistan the creation and Implementation of a highly centralized political system was the only possible way for the government to be able to cope and practically deal with the problems of existent ethnic antagonism and regional warlords in order to create a stable political situation in the country..

The aim with this thesis is to study the risk management in construction projects at the Swedish Road Administration, SRA. Furthermore, the aim is to find the effects of the risk management. The theorem of this thesis is that the positive effects of the risk management in construction projects create additional value to the project. These additional values are that the project itself becomes resilient and that the project goals are achieved without any significant disturbances.This thesis shows that the risk management in construction projects do not follow the guidelines set out by the SRA. This is due to a lack of education in the method and a difficult method all together.

Today there are many studies that have shown positive results in the treatment of ICT at an early age. The focus of the studies vary, and they target everything from the actual Implementation of teaching resources in ICT, to student performance with ICT support. Regardless of the amount of studies on the subject, there is no precise strategy for how to implement, working with ICT, integrate ICT in different subjects, utilizing the hardware and software that is or how it will eventually respond to new technologies. This work will there by focusing on trying to develop a basis for further research and hopefully in the future to develop an ICT strategy at a national level.In order to provide a basis, a comparison was made of ten different schools. The schools were entered into a table showing the similarities and differences .

This paper aims to determine what is decisive for localisation of production units when a company engages in offshoring. By performing a case study on Electrolux and comparing the results with theoretical literature we discuss the implications for manufacturing companies in general. To facilitate a structured analysis we have developed a model dividing the localisation decision into five perspectives and four geographical levels. We have found that the determinants of localisation vary depending on the geographical level of the decision process. Since all geographical levels are interconnected, the analysis needed for a decision on all levels simultaneously is very comprehensive.

Examensarbetet belyser så väl fördelar som nackdelar under utveckling av USB-enheter med PIC processorn PIC16C745 som grund. Processorn används i detta projekt för att möjliggöra en effektiv distansövervakning via USB gränssnittet. I detta projekt har en USB-enhet konstruerats med uppgiften att leverera data från olika givare till en PC. Vidare publiceras dessa data på Internet via en webbserver. Givarna är av typen analoga och binära. Till de analoga givarna hör två stycken temperatur- och en ljusgivare.

The digitization in the Swedish health care sector is rapidly growing. This study investigates whether the digitalization in health care has led to higher quality and an increased value for patients. Interviews with staff in various health care professional categories were conducted to qualitatively study how the Implementation of digitization is perceived in practice by those directly involved. Furthermore, an observation was made, where a doctor was followed duringa workday to study the different digitalization software tools that are being used. Previous studies and other relevant literature accompanied the study of digitalization in health care. Organizational theories were compared with the practical organization management at the studied health care organization, as well as their dependence on other authorities and companies.

The purpose of this paper is to analyze the driving forces and barriers which may exist at the Implementation of green supply chain management (GSCM) within public organizations. Suggestions that may increase or reduce driving forces and barriers to public activities will also be provided, where such is found. The background of the study is that the public sector is such a major customer for many companies / providers, which makes the sector able to highly affect its suppliers. This essay is based on literature studies. The results showed that GSCM is a relatively unexplored area, especially applied on the public sector.

The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.

The purpose of my independent work was to develop and test a task-specific assessment matrix to the students writing logs that occurs in connection with their APL (workplace-based learning). The matrix is based on upper secondary school subject plan House building from The Swedish National Agency for Education and the four courses House building process, House building 1, House building 2 and House building 3 - conversion. Due to the matrix structure, I used the example matrix of Malmö University. The task-specific assessment must both serve as a guide for students in the Implementation of the log writing, and in the evaluation of the assessment work. Both students and teachers then get a common assessment tool for evaluation.
