It is shown how irrigation scheduling and irri-gation technology together increase the irrigation efficiency..

A well known optimization-problem of multiprocessor system is scheduling of tasks. In this paper I use a variant of previous known algoritm, (Fast Critical Path) for scheduling real-time tasks on a multiprocessor system. This is made in a simulation study in MATLAB. The system architecture is assumed to be a MIMD- machine, (Multiple Instruction stream Multiple Data stream) with bus-typologi and message-architecture. Scheduling was made on this system where the number of processors varying from five to ten.

Det problem som denna uppsats hade för avsikt att besvara var varför hemautomation inte används i fler hem. Genom resultaten från en enkät som distribuerades kunde slutsatsen att kostnaden för de befintliga lösningar som finns på marknaden idag inte låg i den prisklass våra respondenter ansåg rimlig. Författarna utvecklade då problemet och ställde sig frågan om en hemautomationslösning verkligen måste ha en så hög kostnad som de befintliga lösningarna har idag. För att belysa detta problem implementerades en egen kostnadseffektiv lösning där respondenternas mest önskvärda funktioner togs i beaktande och en testmiljö implementerades utefter dessa. Resultatet blev en hemautomationslösning med stor potential och med en betydligt lägre kostnad än dagens befintliga lösningar..

The goal of this Master thesis has on the one hand been to create a simulation environment for robots, where not only the simulations in this work can be performed, but also similar robot simulations, and on the other hand to study regulators that can increase the possibilities of rejecting disturbances on an industrial robot. The robot model used has three degrees of freedom, corresponding to the three main links on ABB:s IRB7600. The simulation environment is created using Matlab, Simulink, and Robotics Toolbox. It is constructed in a general way and can be used for simulations of other robot objects created in Robotics Toolbox. A gain scheduling is added to the LQ-regulator, where the feedback matrix is varied depending on the arm position in the workspace.

In this essay I analyze the meaning of the concepts home and at home and the feeling of coming home. What is a home and what different interpretations are there regarding the concepts of home and being at home? What kinds of feelings are aroused by coming home? The world we live in offers great opportunities to travel, which in itself creates a perspective on the meanings of the concepts. The world we live in also forces people to move from their homes, families and countries due to various reasons, which creates various problems and a certain urgency concerning the concepts. I describe basic terms concerning the concepts, both regarding concrete definitions and more abstract notions, and then compare them with my own reflections.         Based on my writing project Coming home I discuss these questions in various ways.

Through analysis of the work of scheduling the doctors at the hospitals of Sundsvall,Gävle and Karolinska in Stockholm this thesis presents some conclusion about howand why a computer system would benefit these very tasks. The reason for doing thisis mainly to save money through more efficient scheduling, but also to minimizeerrors and maximize comfort for scheduler and doctor alike.Scheduling consists of collecting doctors? requests, assessing the need of staff,distribute the available doctors and make sure all tasks are covered throughout thescheduled period of time. The work is often very complex and involves manyvariables ranging from competence to personal whishes and economical constraints.Solving these problems takes a lot of time and energy which could be better spentcuring patients.The conclusion of this thesis is that there is reason to develop such a system to savetime and optimize resources. A description of the system is found in numerous lists ofroles, tasks and prototype sketches which combined shape the content andfunctionality.

The proportion of elderly people in Sweden is increasing. Many of these live at home and as their age increases so does the likelihood of health problems and the need for support, medical attention and care. Personnel working with home help provide a large part of this care, including areas of home-based care that are the responsibility of the district nurse. The purpose of this paper is to describe how home-help personnel perceive their work in the area of home-based care, as their views are an important factor in the ability to provide a care system that funktions successfully. The method employed here is phenomenografic and nine subjects from a home-help group have been interviewed.

This thesis is closely related to the Dynamically Self-Configuring Automotive System(DySCAS) project. DySCAS is a middleware for electronics in an automotive system. Thethesis work has been performed in cooperation with ENEA. Parts of the demonstrationplatform Self configurable High Availability and Policy based platform for Embeddedsystem (SHAPE) developed for the DySCAS project by ENEA have been used in theimplementation phase of this master thesis.The goal of this thesis was to evaluate how the Meteor MW, an offspring of the DySCASmiddleware, should handle QoS and to design a Quality of Service Manager (QoSM) for theMeteor MW that fulfilled hard real-time requirements. The thesis also had the objectiveof analysing and identifying the requirements on such a QoSM from a QoS perspective.Specifically the requirements to guarantee real-time support for applications running onthe MW.

Denna rapport behandlar en undersökning av olika lastbalanseringsalgoritmer i Linux Virtual Server. Undersökningen har gjorts i ett webbkluster (Apache var webbservern som användes) med tre heterogena noder, där operativsystemet var den detalj som skiljde dem åt. Operativsystemen som ingick i undersökningen var Windows Server 2008 R2, CentOS 6.2 och FreeBSD 9.0. De faktorer som undersöktes mellan de olika algoritmerna var klustrets genomsnittliga svarstid vid olika belastning och hur många anslutningar som kunde hanteras av klustret, detta gjordes med verktyget httperf.Undersökningen ger svar på hur ett heterogent webbklusters genomsnittligasvarstid och arbetskapacitet kan skilja sig åt beroende på vilken algoritm som används för lastbalansering. Resultatet visar att den genomsnittliga svarstiden håller sig låg tills en hastig stigning inträffar.

AbstractThe intention of our study was to examine the meaning of home of elderly women and men and how they experience their getting older. We also wanted to see how elderly women and men experience to receive home-help-service in their own home. The study was based on qualitative interviews with elderly women and men. The informants were five women and four men between the ages of 60-84 years. They all had everyday help from the home-help-service.

The aim with this thesis is to study how the phenomenon young people who run away from home (runaways) is presented in the research literature. The question at issue in our thesis is: How does research literature present the phenomenon of young people who run away from home? We have selected seven primary documents that we consider gives a broad picture of the knowledge about runaways. We have a postmodern and a hermeneutic approach in our thesis. Our material has been analyzed on the basis of social constructionist theory and the new sociological paradigm of childhood.

The aim of the study was to understand how the family home secretary reasons and thinks and how they express themselves in their actions towards the family home?s biological children. The method used is qualitative semi-structured interviews, involving six family home secretaries from four different municipalities. The results were analyzed with the help of two theories ? the theory of grassroots bureaucracy and the sociology of childhood theory.

The aim of this paper is to look into the occurrence of home schooling by choice in Sweden. It examines the subject of home education in order to provide an informative overview. It also looks into the legal aspects of the matter to see whether freedom of choice is an issue here when it comes to choosing a certain type of teaching for children of compulsory school age. A further purpose is to provide a comparison of home education in Sweden and in other countries such as the United States, England and Norway.In order to do this we have carried out a secondary analysis of previous research and have also interviewed teachers as well as people with experience of home educating their own children. To accomplish this, we had to look to England for literature and home educating families as home education is a much more common practise in England.The result of this paper strongly indicates that home schooling is not only a legally viable option to traditional schooling, both in Sweden and the other countries concerned, but that it is also a trend that is expected to increase.

The focus of this thesis is on what is considered to be a suitable foster home. For the study to be carried out an application had to be made to get access to the foster home assessments in a medium-sized municipality in Sweden. With the support of attachment theory and theory of standards different categories have been picked out and analyzed in foster home assessements that have been approved. The conclusion to what is considered to be a suitable foster home is a complex issue, as there are many factors that are interacting. Social workers seem to focus on the importance of a family?s ability to provide some kind of stability and security for a child who is considered to be placed within their home.
