The purpose of this study has been to investigate advantages and problems with distributionsystem metering in substations. This report is a study in cooperation with Göteborg Energi.The analyses in this report are made for GENAB, a subsidiary company of Göteborg Energi.To analyse advantages and problems in advance is interesting information for GENAB. Theresult of the report could be based upon whether installation of metering in distributionsubstations will be implemented and in that case which kind of measurement that is relevant.The most relevant and strategic place to implement measurement is at the distributionsubstations on the secondary side (400V), this is due to the placement of the currenttransformers. The measurements in this study involve current, voltage, power, power factor,temperature, energy and power quality.Measuring instruments that are relevant to implement are intended to measure current,voltage, power, power factor, energy and, possibly, power quality in the same measuring unit.It is desirable to have a measuring instrument that measures both energy and power qualitybut since it is most often a cost question, it can be established that energy meters have a lowercost.Metering in distribution substations gives a better illustration of the power network. Thisresults in many advantages for GENAB.

Staphylococcus pseudintermedius (S. pseudintermedius) är en opportunist som ingår i hundars normalflora och den bakterie som oftast orsakar pyodermi hos hund. En alltför frikostig användning av antibiotika inom veterinärmedicinen har selekterat fram nya resistenta bakterier som meticillinresistenta S. pseudintermedius (MRSP). Det är en bakterie som i vissa fall visat sig vara resistent mot alla större antibiotikagrupper som används inom veterinärmedicinen.

Idag implementeras övervakningstjänster allt mer i olika verksamheter, särskilt inom transportbranschen. Implementeringen av övervakningstjänster möjliggör en bättre säkerhet och effektivare arbetsgång i form av att man som företag kan se bränsleförbrukning, lastbilars position och planera rutter utifrån leveransplats. Vi ville få kunskap om hur man övervakar anställda inom andra branscher och hur de anställda reagerar på övervakningen och utförde därför en bakgrundsundersökning där vi läste olika fallstudier från bland annat hemtjänsten, försäljningsbranschen och grundskolan. Vår frågeställning blev var går gränsen för acceptabel övervakning? Vi besvarade den genom att utföra intervjuer i två omgångar med tio respektive sex chaufförer som körde för företag i Bohuslän samt via en bakgrundsundersökning.

Uppsatsen syftar till att undersöka former och frekvens av IKT i ett kommunikativt syfte i skolan.I bakgrunden presenteras att kommunikation med datorerna sätter sin prägel på människors liv och Internet påverkar i hög grad den dagliga tillvaron. Hur tillgången till datorer är i svenska hem och skola samt vilken betydelse datorns placering i har arbetssituationen belyses.I den teoretiska bakgrunden beskrivs vad kommunikation och information är, att vi alltid kommunicerar men det är skillnad på de medel som används. Här belyses även datorns betydelse för kommunikation inom informations- och kommunikationstekniken (IKT). Här exemplifieras vidare datorn i ett pedagogiskt syfte och dess användning inom skolan samt att kringmiljön är viktig.Studien är huvudsakligen baserad på en kvantitativ metodinriktning i form av en enkätundersökning där lärare och elever vid tre skolor i sex olika klasser svarar på frågor kring datorns nyttjande både inom skolan och i hemmet.Resultatet visar att både elever och lärare är frekventa användare av datorer och kommunicerar via IKT i olika former. Båda grupperna är positiva till att i ökad grad kommunicera via IKT.

The largest project at the AICG lab at Linköping University, Cognitive models for virtual characters, focuses on creating an agent architecture for intelligent, virtual characters. The goal is to create an agent that acts naturally and gives a realistic user experience. The purpose of this thesis is to develop and implement an appropriate learning model that fits the existing agent architecture using an agile project methodology. The model developed can be seen as an online unsupervised reinforcement learning model that enhances experiences through reward. The model is based on Maes model where new effects are created depending on whether the agent is fulfilling its goals or not.The model we have developed is based on constant monitoring of the system.

I samarbete med Skanska Sverige AB, Region Hus Stockholm Bostäder har detta examensarbete upprättats. Examensarbetet handlar om bedömning och uppföljning av de allmänna kostnaderna, (AK), inom regionen.  Inom husbyggnation är de allmänna kostnaderna en del av projektets totalkostnad och är i de flesta fall svåra att beräkna. Delar av Region Hus Stockholm Bostäder har arbetat med att ta fram erfarenhetsvärden och nyckeltal, för att få ökade kunskaper om AK i projekten och därigenom underlätta bedömningarna för prissättning i kommande projekt. Syftet är att försöka bidra till högre produktivitet genom att göra bättre bedömning, uppföljning och erfarenhetsåterföring med hjälp rekommendationer. Målet är ta fram en generell beskrivning av en rekommenderad arbetsrutin som ska ha en ?best practice? funktion för framtida arbeten.

The aim of the present thesis is to find deeper knowledge about women?s experiences of sexuality, desire and pleasure during childbirth. In this thesis there are statements of women?s different kinds of pleasurable and sexual feelings and experiences during birth. Furthermore, factors that may influence some women?s feelings and experiences of a sexual kind are discussed in relation to the common notion that women above all feel fear and pain when giving birth.

Farmers are constantly facing changes, and the exposure to risk requires monitoring these changes. Financial risks, institutional risks, market risks and production risks are the different risk categories that the farmers face. Production risks stems from factors the farmer cannot affect or is beyond his control. The crop?s output is the basis for the primary income of agricultural operations, which is why it is important for farmer to manage their production risk. A tool to reduce the consequences of production risks is crop insurance.

In this final thesis a study about welfare indicators in the Swedish milk production has been carried out. The system Swedish Animal Welfare Monitoring Scheme developed by the Swedish Dairy Association has been used as a base and the EU project WELFARE QUALITY® has also been used as a source of information. Focus groups have been used as a qualitative investigating method. This included four focus groups, two with farm auditors from the two different dairies and two with dairy farmers. This method was chosen because in this way one can study how a conversation about a given subject takes form in a respectable way.

According to the Water Framework Directive of the European Union, macrophytes should be used as indicators in the ecological and environmental monitoring of lakes. In the member state Sweden the Environmental Protection Agency has elaborated assessment criteria for determining lake status based on macrophytes. The main focus of this thesis is to evaluate the efficiency of the assessment criteria for macrophytes. In addition the concordance between the ecological status classes of the four quality factors included was analysed.The assessment criteria for macrophytes are based on the total phosphorus preference of the respective species. The focus is thus mainly on the nutrient level of the investigated lakes and the environmental problem monitored is eutrophication.

The market is developing and a growing competition increases pressure on companies to maintain their competitive advantage. Working with cost savings is a way to enhance earnings in a short term but also in a longer perspective. Volvo Powertrain Production Köping has an overall goal; to reduce costs by nine percentages in three years. To achieve the goal, Volvo Powertrain Production Köping works with World Class Manufacturing where the Department of Processing Technology constitutes an important part.Volvo Powertrain Production Köping lacks a standard for how savings within the metal cutting tool area are to be calculated. This makes it difficult to control and monitor their business outcome but it also causes difficulties in controlling the tool suppliers? outcome.

The RoHS Directive was introduced in order to restrict hazardous substances in Electrical and Electronic Equipment, EEE. It currently restricts the use of six hazardous substances/compounds; cadmium, lead, mercury, hexavalent chromium, PBB, and PBDE. The RoHS Directive currently includes category 1-7 and 10 in the categories of EEE listed in Annex 1A to the WEEE-Directive (Waste of EEE). The aim with the report is to investigate and elucidate prospects and obstacles to increase the scope of RoHS. This report mainly considers the inclusion of product categories 8 (Medical Devices) and 9 (Monitoring and Control Instruments).

The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.

The number of weaned piglets per sow and year is a good measurement of sow productivity since it is affected by the number of piglets born alive, the pre weaning mortality (i.e. mortality of live born piglets between birth and weaning) and the number of litters per sow and year. This measure is also closely connected to the number of piglets produced per year, which partly determines the profitability of the piglet producer. During this study, eleven successful piglet-producing herds were visited. Eight of the producers were Swedish and three of the producers were Danish.

Half of Sweden?s 140 000-150 000 sows are culled and replaced by 75 000 gilts annually. Culling of old sows is necessary and allows new breeding material to enter the herd. However, many of the culled sows are young, and have not yet become profitable at the time for culling. Therefore, it is an important question for the pig industry, how to raise gilts to sows with a high and sustainable production level.
