Swedish farmers have the possibility to be subsidized by EU rural development programme for grazing animals on pastures to promote the biodiversity of flora and fauna. The environmental remedy sometimes does not allow supplementary feed and at the same time the Swedish Animal Welfare Act and the Swedish Agricultural Board?s regulations for animal welfare and protection states that animals, in this case horses, shall be fed with food of good quality and adapted for the species. The regulations also state that they should have an individual feeding regime that enables them to maintain a normal body condition. The aim with this master thesis has been to investigate if it is possible to keep Gotland ponies on extensive pastures, during late spring and summer and still maintain animal welfare. The horses were assessed every fourth week using a welfare assessment protocol developed in line with the Welfare Quality® project (submitted, Viksten et al) where physical, behavioural and resourcebased parameters were observed. Twelve one-year old stallions of the breed Gotland ponies purchased from different breeders were used in the study.

At Saab Aerospace in Linköping, components for measurement systems to the fighter aircraft JAS 39 Gripen are developed. In this activity you sometimes want to record the traffic transmitted on the data busses that connects different sys-tems. This traffic on the data busses is using the military standard MIL-STD-1553. This project has aimed to create a system for recording and sending 1553-data. The system is used on an ordinary personal computer, equipped with a recon- figurable I/O card that among others has a programmable logic circuit (FPGA).

Hearing is considered to be the most important sense for the communication between people. Several studies have shown that hearing loss can lead to deterioration in quality of life, reduced social activities, feelings of alienation and hence the increasing incidence of depression symptoms.An early audiological rehabilitation is a prerequisite for proper communication among people with hearing loss. Knowledge has been shown to be of great importance and structured learning and individually targeted approach can be expected to facilitate the audiological rehabilitation.The purpose of this study was to examine the effect of an educational effort for people with hearing loss where the effort was made in the distance within the audiological rehabilitation and was followed-up by professional phone support, through a randomized controlled study.The study group consisted of 69 hearing aid users who were randomized by an independent person into two groups, an intervention group and a control group. The intervention group (n = 33) had access to the book "When the sounds are weaker - on hearing and hearing aids". The group received weekly topic-based information related to the different chapters of the book, in five rounds.

Vi lagrar data mer än någonsin. Idag lagrar vi enligt analysföretaget IDC1 (2007) upp emot 36 gånger mer information än vad vi gjorde under 1998. Men få tänker på säkerheten vid lagring av data. Med säkerhet menar vi här säkerheten att datan som lagrats fortfarande kommer att kunna öppnas om 15 -20 år. Med format i denna studie syftar vi huvudsakligen på filformat. HTML, JPEG, GIF, etc. är exempel på filformat i vilket information kodas för att kunna lagras.

This thesis investigate how energy efficient measures has spread throughout the data centers in Sweden. These questions are put up against a theoretical use of such concepts such as green IT, technological evolution, large technical systems and knowledge dissemination. These theories are used to answer the questions that are encountered during the study, such as how green IT is approached, how big of a role environmental thinking has had in the evolvement of these new technologies. The study has been conducted in a longitudinal manner, it is an observation of the phenomenon that is data centers over a longer period of time. 23 non structured interviews spanning over 27.5 hours of recorded material have been conducted alongside a study of archived material.

Simuleringar används i många sammanhang för att underlätta förståelsen för händelser och förlopp som annars kan vara svåra att överblicka. Ofta är det mycket data som ska förmedlas till användaren.I de fall visuella representationer av simuleringen ska visas i realtid måste data sållas bort så att en interaktiv bildfrekvens uppnås samtidigt som betydelsefull information inte får försvinna.Vid Totalförsvarets forskningsinstitut, FOI, används simulering och visualisering som ett verktyg för att studera de komplexa duellsituationerna mellan medel och motmedel (telekrigduellen). Ett verktyg har i detta arbete tagits fram för att kunna använda sig av de stora geografiska områden som behövs i simuleringarna.Resultatet av arbetet är en applikation som utifrån geografisk kartdata skapar ett 3D-landskap som lämpar sig för realtidssimulering..

Arbetet beskriver ett systemutvecklingsarbete som innehåller kravfångst, analys och design av en data warehouse/business intelligencelösning till Svenska bordtennisförbundet. Svenska bordtennisförbundet/SBTF/ behöver utöka sitt beslutsunderlag för att kunna fatta strategiska beslut. SBTF behöver även få bättre kontroll på sin verksamhet för att kunna sätta, utvärdera och följa upp mål. SBTF önskar lösa detta genom att skapa ett data warehouse till vilket data från de olika systemen laddas för att därefter kunna presenteras för användarna genom business intelligence. I kravspecifikationen framkom att klubbarnas medlemsregister, alla tävlingsspelare, all träningsstatistik och de matcher som spelats i Sverige sedan 2011 var det dataunderlag som skulle ingå i ett data warehouse.

Torstensson, Niklas (2012): Anledningar till olikheter mellan Svenska kommuners skolkvalitet (Causes behind the differences in Swedish municipality´s quality of school) Örebro University.This essay is an explorative case study that will compare four Swedish municipalities quality of local school system against the municipality ´s backgrounddata and a governing document: Skolplan. This study begins in a previous benchmarking study made by one of Sweden?s teachers unions Lärarförbundet. This is a statistical study that ranked the Swedish municipalities against each other?s according to their accomplishments in a number of areas related to their school systems.

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

The Swedish building contractor JMRegion Öst would like to to investigatethe possibilities of developing andstreamlining the production of singlefamilyhouses. JM are producing singlefamilyhouses with prefabricated framesat a rate of about two houses per week.During construction, the different tasksare performed by JM?s own productionstaff but also by varioussubcontractors.When examining the schedules of recentlyproduced projects, it appears that allthe houses are more or less completedeight weeks before the customer moves into the house. During those eight weeksseveral operations are conducted such asinspections, installation of appliancesand cleaning procedures. The inspectionperiod constitutes between 25 and 35% ofthe complete construction period.By conducting interviews, it has beendiscovered that this final phase is anessential security buffer for delays anderrors that often occur.

Syftet med denna rapport är att undersöka vilka riskfaktorer det sociotekniska systemet bidrar med vid inmatning av producerade data till en specifik databas. Denna undersökning använder STAMP-metoden (Systems Theoretic Accidents Models and Processes) för att finna riskfaktorer i systemet. Metoden utgår från att samla data om systemet genom intervju, observation samt analys av annan dokumentation kring databasen för att sedan applicera STAMP-analys på dessa. Resultaten pekade på ett antal riskfaktorer vid inmatningen av producerade data, dessa kretsade primärt kring problem med existerande säkerhetsåtgärder, avsaknad av träning samt bristande kommunikation. Resultaten ledde till en slutsats om förbättringsåtgärder på dessa punkter.

Today Scania give a high priority to the continuous improvements on the quality of their vehicles. To follow up the flaws in product quality, which are recognized by the repairs at the local workshops, material requests are carried through to be able to analyze the defects at the plant in Södertälje ? in purpose to improve the product quality. The material requests are also carried through to compensate the workshop for their expenses and to check that they are working according to the company?s warranty manual.Due to local routines and different distribution structures at the different markets the lead times and the costs caused by the flow of material are hard to estimate.

The aim of this study was to describe the mental and social causes to obesity among children and adolescents, their consequences and what preventive interventions that are used. The method used by the authors was to search for scientific articles in the database Medline, using the keywords: obesity, overweight, child, body image, social, family, school, depression, nursing, quality of life, social support, prevention and support. The study was performed as a literature review, with a descriptive design, and the result contained 22 scientific articles. The main result of this study showed that obesity among children and adolescents is not only an individual problem, it affects the whole family. The main causes to obesity among children and adolescents are the socioeconomic status of the family, their lifestyle, and even gender to a certain degree.

Transportation of pigs might be a welfare problem. Stress during and after transportation can negatively affect the meat quality or cause carcass damages, which leads to major economic losses every year. The transportation chain can be divided into several stages; loading, transport and unloading. This literature review focuses on unloading of pigs from a transport. When arriving at an abattoir pigs can be fatigued and need to be as smoothly unloaded as possible.

An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.
