The title of this essay is ?Collaboration between social services and schools?. Research shows that many children and youth who are badly treated are not noticed and do not receive the help that they need. This could be due to the lack of collaboration between different authorities and professionals. The purpose of this study is to describe and analyze how the social services and schools are collaborating in terms of children and youth who are badly treated or is at risk of being badly treated and to identify what factors make collaboration possible and hinder it.

Genom vår undersökning ville vi ta reda på om SALSA, Vodafones data warehouse tillgodoser användarnas informationsbehov. Som stöd för vår analys jämförde vi befintliga teorier inom områdena information samt data warehouse, med tillämpning i verkligheten genom vårt referensföretag. Undersökningen har utförts genom skriftliga intervjuer samt enkäter, där två olika undersökningsgrupper ingått. Den ena gruppen har utgjorts av SALSAs utvecklare och den andra av SALSAs användare. Den hypotes som vi arbetat med är "SALSA tillgodoser användarnas informationsbehov" med underfrågorna "Vilka krav kan användarna rimligen ställa på SALSA?", "Vilken information saknar användarna att få fram från SALSA?", "Vilka förslag på förbättringar gällande SALSA har användarna?" samt "Räcker användarforum för att framföra användarnas synpunkter på SALSA?". Då vi analyserat och bearbetat materialet från enkätundersökningen samt besvarat våra frågeställningar, har vi verifierat vår hypotes.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

Däremot kan dator/Internet vara nödvändigt i vissa moment i undervisning för att uppnå den moderna tidens krav.Nyckelord: Data/Internet, IKT, IKT som verktyg i undervisning, IKT utveckling, datakunskap.

With numerous applications in both military and civilian life, the demand for accurate 3D models of real world environments increases rapidly. Using an airborne laser scanner for the raw data acquisition and robust methods for data processing, the researchers at the Swedish Defence Research Agency (FOI) in Linköping hope to fully automate the modeling process.The work of this thesis has mainly been focused on three areas: ground estimation, image segmentation and classification. Procedures have in each of these areas been developed, leading to a new algorithm for ground estimation, a number of segmentation methods as well as a full comparison of various decision values for an object based classification. The ground estimation algorithm developed has yielded good results compared to the method based on active contours previously elaborated at FOI. The computational effort needed by the new method has been greatly reduced compared to the former, as performance, particularly in urban areas, has been improved.

The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

SAAB Security and defense solutions i Järfälla har ett system som används av militären för övervakning av flygplan. Systemet visar på en datorskärm en karta över Europa där flygplanen visas med markeringar från data som samlats in av radars. Då data samlas in med en låg frekvens visas ytterligare en markering som kallas målspår. Dessa målspår beräknas fram med tunga matematiska beräkningar och sköts av datorns processor.Det finns ett önskemål om att flytta dessa beräkningar till datorns Grafikkort med hjälp av OpenCL och därmed frigöra processorns resurser. OpenCL har implementerats med två olika Java bindings och prestandaskillnader mellan dessa samt de ursprungliga beräkningarna har undersökts.

This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.

This study deals with some contested issues regarding prehistoric cultural development in Amazonia and the colonial impact on the native inhabitants of the area. It focuses on the relation between groups belonging the language families of Tupí and Gê, on one hand, and the different ecological zones that they inhabit, on the other. GIS mapping is used to visualise the distribution and movements of these groups in relation to ecology and the impact of European colonization. GIS is shown to be a useful methodology for analysing historical data derived from written sources and maps. The results of these analyses are discussed in the light of different theoretical perspectives.

Bakgrund och problem: I takt med att allt mer information genereras har en problematik uppkommit kring hur man skall hantera denna i organisationernas IT-infrastruktur. Utbudssidan hävdar att deras nya lösningar kommer att revolutionera möjligheterna kring analys av alla olika former av data. Tillgång bättre information och förbättrade analysmöjligheter kan få stora konsekvenser för ekonomistyrningen förutsatt att det används på rätt sätt. Syfte: Vårt syfte är att identifiera och beskriva innebörden av begreppet Big Data samt hur de teknologier och verktyg som finns kan stödja ekonomistyrning. För att sätta området i ett större sammanhang har vi studerat begreppet utifrån tre aktörers perspektiv.

Very often the interesting variables are explained by several underlying variables and in statistical analyses it is common to study the relationship between variables and groups of variables. Because of this multivariate analysis is commonly used in both science and industry. There are two problem with both univariate and multivariate analyses. One is when the variables are correlated. The other is when the number variables of exceeds the number of observations which makes the matrices algebra used in the analysis impossible to execute.

There is a need for productivities data and data for different types of machines for comminution of logging residues. The lack of data and studies on GROT comminution makes it difficult to evaluate different chains for handling of residue fuels and make system analyses.Four types of machines with three different working principles were compared at six studies during winter conditions. Three to eleven trials during 9.5 to 30.7 minutes were made on each machine. Samples from the produced material at each study were sieved to determine the size distribution of the comminuted material. Samples were also taken from the studies for determination of moisture content.

People are constantly using there friends in order to ask for a favor or to get hold of some information. This is usually done unconsciously and it is just viewed as everyday life behavior. The function and the use of these links definitely have a value, which means that it can be viewed as a form of capital. But this capital is not caught in the traditional theories of physical capital or human capital; it demands it?s on theorization.

The thesis is an examination of the methods that are appropriate and long-term choice to obtain clamping force and secure screw joints in production. The employer, Scania CV AB, transmission manufactures axle gears to all trucks produced in Södertälje. One of the most common assembly elements is screw joints, where the clamping force is essential to achieve a secure joint. Current methods to secure the joint is due much of the friction effect and is an indirect method to measure the clamping force. The clampforce accuracy becomes more widely with torque angle control.
