Fabriksplanering ur ett hållbarhetsperspektiv
In the last decades the continuous work for more sustainable manufacturing has become a large part of the manufacturing companies? operations. It is also well known that the factory planning shapes the manufacturing process to a great extent. Consequently it is logical to assume that the manufacturing companies? factory planning process plays a major role in the work for increased sustainability.
Support Vector Machines for Classification applied to Facial Expression Analysis and Remote Sensing
The subject of this thesis is the application of Support Vector Machines on two totally different applications, facial expressions recognition and remote sensing.The basic idea of kernel algorithms is to transpose input data in a higher dimensional space, the feature space, in which linear operations on the data can be processed more easily. These operations in the feature space can be expressed in terms of input data thanks to the kernel functions. Support Vector Machines is a classifier using this kernel method by computing, in the feature space and on basis of examples of the different classes, hyperplanes that separate the classes. The hyperplanes in the feature space correspond to non linear surfaces in the input space.Concerning facial expressions, the aim is to train and test a classifier able to recognise, on basis of some pictures of faces, which emotion (among these six ones: anger, disgust, fear, joy, sad, and surprise) that is expressed by the person in the picture. In this application, each picture has to be seen has a point in an N-dimensional space where N is the number of pixels in the image.The second application is the detection of camouflage nets hidden in vegetation using a hyperspectral image taken by an aircraft.
Träning med mål och coachning för patienter med knäartros
Aim: To investigate if physical exercise in combination with coaching will reduce pain and improve knee function in patients with mild to moderate osteoarthritis in the knee compared to physical exercise alone.Method: The study consisted of 42 patients who were randomized to either an intervention group or a control group. Both groups followed a standardized training program at home, but the intervention group received additional support with regard to the aim of their training, as well as extra coaching during the training period of ten weeks. A Visual Analog Scale (VAS) was used to evaluate the patients? pain. A 10 metre walking test, the Index of Muscle Function (IMF) and the Knee injury and Osteoarthritis Outcome Score (KOOS) were also used to evaluate knee function.

Dimensioneringen av revisionens budget
This study represents the different factors that may have an influence on the budgetproposal in the local government for the revision. The revision in the local government is an important part of councillors and public insight into the different activities. The budget for revision decides how much of the activities runned by the local government can be observed by the elected representative accountant. The aim of the study is to see how the following variable affect the dimension of the budget appointed for revision. We have used Institutional theory, theory that contains the role-play between guardians and advocates and Agent theory with help of accountability.The dissertation is written in Swedish..
Modeller för brösthöjdsålder för tall och gran :
The purpose of this study was to develop two types of prediction models for Scots Pine
and Norway Spruce. The first type for calculation of the stump diameter under bark the
year the tree reached breast height (Dstubh130). The second type for calculation of the
annual difference, e.g. the number of growth years between stump height (0.2 m) and
breast height (1.3 meters above ground level). The primary thought with these prediction
models is to obtain the breast height age in the trees on basis of the number of annual
rings at stump.

In that way the user can increase and decrease the fan speed, even when the user not is home.
Broms- och styrsystem för möbeljalusier
This report is the result of a master thesis at the Department of Mechanical Engineering, Division of Industrial and Economical Development, at Linköping University of Technology. The project was carried out on behalf of Fanerami AB, Mjölby and includes 20 weeks of full time schedule work.Cabinets with vertical mounted roller shutters all share the same problem, namely weight balancing. A roller shutter has an equilibrium area where the sum of the different forces acting on the shutter equals zero. As the shutter leaves that area it will pick up speed as it falls towards the bottom. When the shutter hits the bottom of the cabinet there is a potential risk of getting fingers caught and in this project a solution to prevent this from happening was to be presented.In this project, three concepts have been generated with the following different purposes:?In concept 1 the risk of getting any fingers caught when the shutter closes was to be eliminated in an efficient and inexpensive way.?In concept 2 the roller shutter had to be balanced at all time providing the possibility to keep the cabinet open in any position.?The last and most challenging task was to create a remote controlled TV cabinet.
Fysisk självkänsla hos barn och ungdomar med Aspergers syndrom
Background: It is common that children and adolecsents with Aspergers syndrome have impaired motor skills and are less physically active than neurotypical children and adolecsents. Studies conducted on neurotypical children shows that children and adolecsents who are regular physical active also have a good motor control and a good physical self-esteem. The purpose of this study was to investigate the physical self-esteem of children and adolescents with Aspergers syndrome. Study Group: 36 children and adolescents aged 9-15 years with a diagnosis of Aspergers syndrome was asked to participate in the survey. 18 children, 16 boys and 2 girls, responded to the questionnarie about physical self-esteem which 17 of the answers could be used in the study.
Inhalationssedering på CIVA : en retrospektiv beskrivning
Bakgrund: Patienter som ventilatorvårdas på intensivvårdsavdelning behöver ofta någon form av lätt sömn (sedering) för att tolerera endotrachealtuben och ventilatorbehandling. De traditionella intravenösa läkemedel som ges har lång halveringstid och det är stor risk för kvardröjande effekter. Syfte: Denna pilotstudie syftar till att studera sederingsdjupet enligt MAAS hos de patienter som blivit sederade med inhalationsgas, kontrollera vakenhetsgraden enligt GCS hos dessa patienter efter avslutad sedering, samt beskriva vilka patientgrupperna är som fått inhalationssedering. Metod: Journalgranskning där resultatet har analyserats och kategoriserats, därefter har en sambandsanalys gjorts. Resultat: I resultatet identifierades 3 patientkategorier som fått isofluransedering: patienter med hotad luftväg som förväntats behöva kort sederingstid och snabb väckning, patienter som var svåra att sedera optimalt med intravenös metod samt patienter med organsvikt där risk för ackumulation och/ eller förlängd elimination av läkemedel förelåg.
Svenska Basketbollförbundets Regionsutvecklingsprojekt U15 : En studie av förändringsprocessen för regionsutvecklingsprojektet och regionsledarnas attityder till organisationsförändringen
In 2009, the Swedish Basketball Federation started a Region U15 development project in order to change the structure of the regional organization to get into a more transparent and similar operations throughout the country. My purpose is to study the attitudes to the change among the region leaders in the regional operations and evaluate the change from an organizational perspective. The study is primarily based on the following questions: What are the experiences of the change process among the region leaders in the regional organization? How involved have region leaders been in the changing process? Which are the positive and negative aspects with the regional operation today? What can be done further to develop the regional operation and to what extent do the organizational change follow general organizational theories? In my study, a qualitative method was used in terms of interviews with 8 regional leaders to understand their attitude to the project and the changing process. To analyze the results of the region leaders ?responses, a transcription have been made.
Energiåtervinning av turbintätningsånga : En fältstudie hos Bomhus Energi AB
HiGtech är en projektgrupp på Högskolan i Gävle vilka konstruerar och bygger energisnåla tävlingsfordon. Ett av fordonen tävlar i Shell Eco Marathons prototypklass för bensindrivna förbränningsmotorer och drivs av en på högskolan konstruerad motor. Motorns effekt överförs till en kedjetransmission via en inköpt och modifierad centrifugalkoppling. Den nuvarande centrifugalkopplingen väger cirka 1,5 kg. Då en stor faktor för tävlingsresultatet är fordonets rullmotstånd, vilken beror av fordonets vikt, har målet med detta arbete varit att konstruera en specialanpassad centrifugalkoppling, vars vikt endast är hälften så stor som motorns nuvarande koppling.
