During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.

The main purpose of this bachelor?s thesis is to examine how Swedish upper secondary school librarians and related staff relate to the online encyclopaedia Wikipedia. The research is placed in the all-embracing context of information literacy and source criticism on the Internet. The study was carried out in the form of qualitative interviews and based on two theoretical bases: firstly, the concept of cognitive authority stipulated by Patrick Wilson, and secondly the idea that Wikipedia has a draw towards late modern epistemological assumptions. The latter theory was also associated with the perceptions of knowledge among the library staff interviewed.

In Sweden whenever trains or maintenance workers want access to the railway system, their requests of usage and movements are being supervised, granted and handled by train dispatchers. The profession holds a key role in making the complex railway system work in terms of efficiency, safety and delivering on-time arrivals. This master thesis, delegated by the Swedish Transport Administration, has been carried out at the Division of Human Computer Interaction at Uppsala University and at the train traffic control center in Gävle. The aim has been to map what information the train dispatchers use in order to make safety-related decisions concerning their working goals. And further to describe and analyze how the train dispatchers, visavi their tools and systems in the work domain, gather necessary information.The result indicates a complex, diverse and spread out setting of different programs, procedures and tools that make satisfactory fulfilment of efficiency, safety and punctuality in relation to the time table hard.

 The number of hidden refugees in Sweden is estimated to be at least 15,000. The law, which only allows this group a very limited access to health care, can be considered to clash with the human rights and the ethical codes related to the health care professionals.The aim of the study was to examine how the personnel in public health care may experience treating hidden refugees and which ethical conflicts that may be connected to this. The study, which is of a qualitative descriptive design, is based on eight semi-structured interviews. The interviewees were trained nurses and mid-wives in an emergency room, a maternity ward and a health care centre for asylum seekers.The experience of treating hidden refugees amongst the informants was limited. The study proved that the knowledge of laws and guidelines regarding hidden refugees amongst the interviewed health care personnel was poor.

The economic situation in the Swedish agricultural industry is currently experiencing a development towards larger units. This progress occurs simultaneously as farmers in cooperation more frequently make investments to decrease risk exposure and to improve the financial result. The purpose with this thesis is to study which advantages and problems a group of farmers experience after a common investment in a small-scale seed production. The aim with this investment is to increase the level of vertical integration in their respective agricultural firms and the results will be analyzed from an economic point of view. At present, the farmers are all seed producers with considerable cultivation areas.

The aim of this essay is to create an understanding, of how teachers comprehend knowledge, grades and tests in a school context. It is important to get a grip of the different parts of the teacher?s reality. The test, the grades and knowledge are deeply connected as a part of a whole. The teachers view on knowledge can not be understood without asking about the practical parts of their work and understand how the different parts are dependent on each other.The main material consists of interviews with four teachers that work in a public mandatory school in the south suburbs of Stockholm.

Occupational Health Service (OHS) has an important role in society. It is designed to prevent illness and strengthen the health of workers. OHS operations and development are currently being studied at the School of Technology and Health at the Royal Institute of Technology in Sweden. One of the industries studied is the home maker service. During the 2010s were such employees one of the most ill groups in Sweden.This master's thesis in occupational environment development and change management focus on examining the special knowledge an OHS and its clients in one home maker service need to strengthen the workers of the industry and find out how the interaction between OHS and home maker service works and how it could be evolved.A qualitative study was conducted in a Swedish city on the basis of an organizational perspective.

The aim of this thesis is to study young people's views on support, knowledge and change. The eight participants in this interview study are between 14 and 19 years old and they share the experience of growing up in a family where a parent is a substance misuser or mentally ill.Childhood sociology has been used as a theoretical framework. The main finding is that emotional and practical support based on the young person's needs and knowledge based on the ideas of empowerment and agency promotes change. The four most important insights according to the young persons are: My parent has got a problem. It is not my problem.

The idea to develop  a platform for a PID-controller came from the need to control the temperature in  an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.

Övergången från CATIA V4 till CATIA V5 innebär nya möjligheter för konstruktörerna på Scania att arbeta med Knowledge Based Engineering, KBE, för att effektivisera och kvalitets-säkra sitt arbete. Då CATIA V5 är en ny plattform som innehåller verktyg med samlingsnamnet knowledgware, för att bygga in kunskap i modeller ville Scania undersöka potentialen i att arbeta med KBE, och hur detta skulle kunna ske på Scania. Vid traditionell produktutveckling tas en helt ny artikel fram vid behov och ofta innebär detta att arbete som tidigare utförts, görs om igen. Syftet med arbetet är därför att undersöka huruvida KBE i CATIA V5 kan erbjuda möjligheter att återanvända kunskap från tidigare arbete och samtidigt kvalitetssäkra denna, samt utreda vilka knowledgewarelicenser som i så fall kan vara lämpliga för Scania.För att göra detta har en litteraturstudie genomförts för att undersöka vad som har gjorts inom området, och även en intervjustudie har utförts inom R&D på Scania. Vidare har sakkunniga på Linköpings Universitet och Tekniska Högskolan i Jönköping intervjuats.

This thesis is a case study of the search function on the University of Uppsala?s web site. The search function in this study was chosen since it exists on a large and complex web site and there were apparent lacks in the old version of the search function. The thesis highlights some of the problems that can appear in the development of a search function on a local site. One interesting find is that one of the most difficult issues is organizational and not technical.

This thesis has created an image of the exchange of information among teachers in the Swedish upper secondary school. The study indicates that the exchange of information seems to be limited at all levels and the exchange that takes place outside the own teaching team occurs mainly through teachers personal networks. The study also shows barriers that may exist and the opportunities that an increased exchange may generate. From the picture that the empirical material provides and the theory that is presented a discussion is made around how IT can best support the organizational learning in schools. A concrete proposal is that at national level an IT platform should be created, which primarily focuses on materials that are created by its users and has an open architecture with a single login..

This thesis deals with information provision to the knowledge intense biotechnology businesses of Ideon Science Park in Lund, Sweden. Previous research concerning the information needs of Science Park companies has been conducted from the information provider s perspective. Instead, we apply a user perspective to find out what information needs these companies have, and how they prefer to acquire information. Central terms are: information, -needs, -acquisition, -consciousness, -strategy, small and medium sized enterprises, scientists and engineers, information (resources) management, networks, tacit knowledge, knowledge transfer and innovative milieux. The companies need scientific and business information; the latter is easily obtained within Ideon.

The report is the result of a master thesis at ENEA AB during the fall of 2009. Itaims to create a specification of flash memory management system which focuseson power efficiency and low RAM usage for embedded systems, and to design andimplement a prototype of such a system to facilitate further development toward thecreated specification. The system used by ENEA today is a Flash Translation Layer(FTL). It has a complex structure which prohibits modifications and customization,therefore a new flash memory management system needs to be developed.The suggested solution uses a translation layer called Metadata FTL (MFTL), wherefile system metadata and userdata are separated from each other in order to improveperformance. The partition holding userdata uses a block-level mapped translationlayer system called Fully Associative Sector Translation FTL.
