The purpose of this master?s thesis is to evaluate anew method for load-shedding, the voltage controlled underfrequency load-sheddingdeveloped by ABB. This report presents a comparison between conventionalunderfrequency load-shedding and this new method for load-shedding.

In this report a system for Rapid Control Prototyping, RCP, is evaluated through animplementation of the motor control methods Field Oriented Control, FOC, and Space VectorPulse Width Modulation, SVPWM. The evaluation emphasizes on time-consumption andresource utilization on the used hardware and on usability for of software.A new mechatronic laboratory is under development at ABB Corporate Research in Västerås. Itwill be used for both mechanical and motion control design using existing and new hardware.The control structure in a traditional robot system will be interfaced to a rapid prototypingsystem which should allow easy changes to algorithms at different levels in the system.The system designated for this project comes from National Instruments and constitutesLabVIEW Real-time and FPGA module as the software tools. The hardware is a NI Single-Board RIO (Reconfigurable Input Output), sbRIO, development board including a Field-Programmable Gate Array, FPGA, from Xilinx and a microprocessor from FreescaleSemiconductor. Graphical programming is performed in the LabVIEW environment, andthrough Xilinx tools the LabVIEW FPGA code is compiled to VHDL code.A pre-study was carried out to clarify the concept of RCP and investigate different systems forRCP and their traits.

Young people?s political influence has been surveyed, studied and discussed several times in Sweden during the last decade. There is a fear among the politicians that the young people are not interested in politics, especially not in party politics. On the other hand there is, among the youngsters a feeling of invisibility, not being seen or heard or for that sake respected. There are a lot of formal possibilities for young people?s political influence, but there are not as many real possibilities or situations to actually practice these possibilities.

In relation to the development of IT-products it is very important that the software supplier is aware not only of the target group but also the field of application. Usability should characterize the whole IT-design process as, in relation to this context, design includes more than merely those aspects which are visible to and thus can be interpreted by the naked eye. The study examines the specific qualities and properties that substantiate the usability and the demands that a customer rightfully expects from an IT-product. The user and the customer are highlighted in the same context in order to demonstrate that it is through the customer that an IT-product is defined as being useful. Thus, from this perspective, the user and customer can be considered as being the same person.

Strong relationships are something that is really important for companies to succeed with, in purpose to increase and protect their market shares. After major research on the subject, it has been found that variables like exchange of relationship, trust, control mutability, satisfaction and commitment are important in the establishment of measuring a relationship. The purpose with this thesis was to: increase the knowledge on how companies measure, and then consequently evaluate, their relationships. To answer the purpose of the study we chose to do a case study at Stadium AB, which is a retailing concern with a high level of customer contact on a daily basis. The conclusion is that trust most likely is the key variable in measuring relationships.

Vid utveckling av nya system finns det flera olika modeller/metoder att använda sig av, till exempel prototyping eller vattenfallsmodellen. Denna uppsats beskriver hur utvecklingen avett webbaserat system för registrering av datorer kan ske med hjälp av vattenfallsmetoden. Fokus på detta arbete ligger förutom själva utvecklandet av registret också på dokumenteringen av de olika stegen som följts enligt vattenfallsmodellen. Detta arbeteförsöker också svara på om denna modell är lämplig att använda vid utvecklingen av liknande system. Uppsatsen tar också upp fördelar och nackdelar om kan uppkomma vid användandet av denna modell..

Children's Need In Focus (BBIC) is a processing and documentation system used in child welfare cases to investigate, plan and monitor interventions. The BBIC has had a breakthrough in Sweden and out of the country's 290 municipalities, there are 284 that use the system daily as a tool in cases involving children. The purpose of this study was to examine how social workers experience the BBIC as a working system and what strengths and weaknesses there are in the BBIC concept. We wanted our study to examine how the BBIC could possibly enhance the quality of childcare matters, but also how the BBIC could potentially increase children's participation in cases. We have performed qualitative interviews with eight social workers who work in four different municipalities where the BBIC is applied daily.

ROS är ett produktnära system som stödjer planering och återrapportering i stålverket. Sandvik vill undersöka möjligheterna att modernisera användargränssnittet på detta system som idag är terminalbaserat till ett modernt grafiskt interface. Två metoder analyseras, den ena innebär att använda en kommersiell produkt för screen scraping och den andra metoden är Web Services Integration Toolkit som är freeware. Resultatet från analysen visar att Web Services Integration Toolkit klarar av att uppfylla de mål som är satta. En testkörning av Web Services Integration Toolkit görs också på ROS och resultat visar att metoden fungerar även fungerar i praktiken..

Subclinical mastitis (SCM) is a well-known problem in the dairy sector, where it causes severe economic losses mainly due to reduced milk production. This is a problem not only in the western world but also in developing countries. Surveys from different developing countries have shown a SCM prevalence of 52.4 ? 88.6 % at cow level and 26.7 ? 63.2 % at quarter-level. To combat mastitis is important to optimize the milk production of the cow.

To render outdoor scenes with lots of vegetation in real time is a big challenge. This problem has important applications in the areas of visualization and simulation. Some progress has been made the last years, but a previously unsolved difficulty has been to combine high rendering quality with abundant variation in scenes. I present a method to mathematically generate and render vegetation in real time, with implementation in the scene graph Gizmo3D. The most important quality of the method is its ability to render scenes with many unique specimens with very low aliasing.

 The aim of this paper was to investigate how many students studying Swesdish as a foreign language, at secondary school level, in Tierps kommun, that have dropped out and their reasons for doing so. The reason for this is the report from Skolverket, stating that the rate of drop outs at this level is very high. To investigate this, a quantitative method was used. A questionnaire was sent out to all the students that dropped out 2005-2008. The result showed that the two main reasons for leaving their studies were that the individuals had found a job or thought the studies were too hard. The research also showed that the majority of the students had not been in contact with Career counseller prior to ending their studies. We came to the conclusion that there might be a need for developing the teaching and to work out routines for guidance at drop out situations.

This study was about disability organisations opinion concerning ICF: s importance in their work to receive the same recognition and human rights for their members as citizens. The aim has been to elucidate disability organisations awareness about and use/non use of ICF and to increase the understanding of ICF: s importance for recognition and redistribution. Three different methods have been used: literature study, questionnaire survey, both on counties' (27) - and national (26) level and interviews (5) on national level. There is also a distinct difference between the disability organisations that represents people with visible impairments, who don?t think that ICF is so useful and they that represent people with invisible impairments, who thinks that ICF is a useful tool.

 SammanfattningKravhanteringsprocessen är en av de viktigaste faserna vid utvecklandet av ett IT-system. Kravhantering är alltså grundläggande för att utveckla ett stabilt system som uppfyller beställarens önskemål. Med en väl utförd kravhantering som grund får man ett system som är fritt från bristfälliga fel, utvecklandet av systemet går även till på ett effektivare sätt. Vid byggandet av ett system eftersträvar man alltid en framgångsrik mjukvara. Kravhantering ses som den viktigaste faktorn vid utvecklandet av ett IT-system.Föreliggande studie genomförs som en litteraturstudie där undersöks vilka brister som är vanligt förekommande under kravhanteringsprocessen.

This paper examines the European Commission?s, newly established, ?Register of interest representatives? The analysis is divided in two parts, first I analyze the registers purpose, the kind, and detail, of information it contains and the different kinds of groups that are supposed to register. After that I analyze the organizations in the register more thoroughly, using a database of my own creation. The database was constructed with information drawn from the register, as well as information from external sources. Regarding the design and purpose of the register, I find that improvements in the design are needed, if the register is to fulfill its purpose.

The computer consultant company Create in Lund AB wishes to facilitate their invoice routines, as it at present is required that the administration finds and compares information from two different systems.The purpose of this thesis is to develop an invoice management system that simplifies the invoice management process for the administration at Create. During the development of the system, I have chosen to follow the software development process Unified Process and also tried to find design patterns that can be applied to the integration.The result of my project is a self-contained application developed using the Java programming language that communicates with the databases of the other two systems and presents relevant information to the user as a set of invoices. Of the 23 design patterns I studied, I used four of them in the invoice management system. However I couldn?t find any connection between any design pattern and the integration of systems.
