Prediktering av komponenters mognad/kvalitet utifrån felkodsutfall
This master thesis has been carried out at Scania R&D at the department of Powertrain Control System Development during the winter 2011/2012. The purpose of the thesis was to produce a method that with the result of troubles codes from the field testing would be able to say something about the maturation of a component, in this case the VGT, variable geometry turbocharger. To start with, it was necessary to investigate hich information was available. After the information been summed up in tables and charts, this so that it was possible to understand the huge amount of data, the calculations started.Since the thesis was about maturation of a component the proportions were calculated of components that had a trouble code in contrast of those who passed the test without a trouble code. This Thesis includes background information about basic of statistics and about the company Scania and its testing process.
Förekomst av penicillinkänslighet hos blododlingsisolat av Staphylococcus aureus
Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.
Effekter av 2 timmars fysisk träning per vecka på uthållighetsstyrka, kondition, rörlighet och kroppssammansättning. : En 7 veckors interventionsstudie på personer med stillasittande arbete.
Studien avser att studera effekterna av arbetsplatsförlagd fysisk träning 2 x 60 minuter/vecka i 7 veckor hos personer med stillasittande arbete påVO2max, rörlighet, uthållighetsstyrka och kroppssammansättning. Vi använder oss av en kvantitativ metod som består av datainsamling genom tester före och efter träningsperioden för både interventionsgruppen (n=25) och kontrollgruppen (n=11). Resultaten visar på signifikanta skillnader hos interventionsgruppen på variablerna VO2max (p=0), visceralt fett (p=0,001), fettmassa (p=0,001), vikt (p=0.006), Body Mass Index, BMI (p=0,005), uthållighetsstyrka enligt Sörensens isometriska uthållighetstest (SIU) (p=0) och Trunk Curl Static Endurance test (TCST) (p=0,045), rörlighet i halsrygg (p=0,010) och rörlighet i hamstringsmuskulatur via Sit and reach test (p=0). Inga skillnader ses i blodtryck och, skelettmuskelmassa i armar, bål och ben. Inga signifikanta skillnader ses hos kontrollgruppen oavsett variabel. Slutsatser av studien är att man kan se effekter genom denna typ av intervention på flera olika variabler och förslag till framtida forskning är att försöka utesluta samverkan av andra faktorer för att ge en mer exakt bild av den fysiska träningens effekter på arbetsplatsförlagd träning..
CFD simulering av en fyrtakts Otto motorcykel motor
This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.
LCC-kalkyler i byggbranschen : förutsättningar och tolkning av resultat
Background:Life-cycle costing (LCC) is an investment calculation that takes intoaccount operating costs throughout the investee lifecycle. LCC calculations are mainly usedto evaluate investments that have no revenue side. Attempts to apply the LCC calculations forbuilding-related investments have occurred since the 1980s. Despite the advantages ofusing LCC calculations, use has not passed through in full. The main obstacles have beenidentified as a lack of relevant input data, and insufficient experience of workingwith LCC calculations.
Skillnaden i perception mellan hockeyspelare på professionell kontra icke professionell nivå
Purpose: The purposes of the current study were to investigate whether there were any differences in the perceptual ability between professional and non-professional ice-hockey players and whether professional players are better at distinguishing, paying attention to and concentrating on what is important during intense physical activity. Method: Twenty male ice-hockey players (10 from both the Swedish first and third divisions) participated in the study. Wingate test were used for physiological measurements while three psychological tests were presented in front of the participants. Stroop, Flanker and Fast counting tests were used to measure perceptual and coping abilities during intense physical activity and the differences between the two groups. Results: Fast counting and Flanker word 2 tests showed a significant difference between the two groups, whereby the professional groups was faster and more accurate than the non-professional group in answering.
Hygienisering av torkat bioavfall
The main project Dry preservation of food waste from households includes a new technique concerning drying and storage of dried biowaste as well as a study of the sorting of household waste and further usage of the dried biowaste. A question asked in the project is, can the dried biowaste be used as a soil amendment? If organic waste is used as a soil amendment, precaution concerning hygienic safety risks has to be accounted for. The objective of this M. Sc.
Observiaire och film som analysmetod för cykeltrafik : En fallstudie på Götgatan i Stockholm där omställningen till supercykelbana utreds
The goal of this thesis is to analyse whether the method ?Observiaire? is of any use for traffic analysis. The method consists of analysing film material, preferably before and after changes are made to an area, by answering a survey for the users that are observed within the population. The method also opens up for deeper qualitative analyses which are rooted in the quantitative data collected from the survey-study. In this study we analyse the method by applying it to the case study of the changes made at Götgatan in Stockholm, where a green wave was implemented and the bicycle road widened.

Undersökning och utformning av ett generellt datainsamlingssystem i LabVIEW
This report is the result of a diploma work made at IMT at US in Linköping. The purpose of this piece of work is to investigate the possibility to design a general program for data-acquisition using LabVIEW, suiting different hardwares and connections. Great importance has been attached to communication with serialport, using bluetooth, because different wireless PPG-instruments has been developed parallel to this project. These PPG-circuits uses this type of serialcommunication. Communication with USB, GPIB and analog connection has also been examined and analog communication has been tested practically.
Ledarskapsstilar : En studie över skillnader i ledarskapsstilar mellan Sverige och Grekland
The recent globalization has to some extent reduced the importance of specific cultures and instead creates a focus on the variation these different cultures provide. Under these circumstances the leader must adapt his leadership to face these new circumstances. The organisations today have to face these new leadership challenges which the global expansion brings. This is a prerequisite for organizations if they want to succeed and be more competitive in a more demanding environment.There are still big differences between the business cultures. There are also differences in the companies? home arena, between groups in the society and all the way down on a family level.
Karriärpaketet -Ur den sökandes perspektiv
Vår undersökning syftar till att få reda på hur en ung vuxen, runt 20-25 år upplever att använda karriärpaketet och om de får nya tankar eller idéer efter användandet. Vi undrar även om detta valstöd kan ersätta en vägledare. Vi utgår från den sökandes perspektiv.
Vår undersökning bygger på data som vi erhållit genom kvalitativa intervjuer med fyra unga vuxna i ålder mellan 21-24.

Avancerad scenarioanalys för ambulansplanering
This paper describes the development of a simulation model for the ambulance flow in the Västra Götalands-region of Sweden, and an analysis tool for the output of the simulation model. The aim of the simulation model was to be able to evaluate the outcome from changes in the ambulance operations, such as a reorganization of ambulances or an increase in intensity of the ambulance calls. This evaluation is meant to serve as decision support for the strategic planning of the ambulance operations. The analysis tool was developed to visualize the abundant geographical data produced by the simulation model in a meaningful way. The simulation model was validated against historical data which showed that the dispatch time for the highest prioritized ambulance calls corresponds well with historical data.
Vilket bränsle går du på? : En kvantitativ studie om användandet av kosttillskott
Syfte och frågeställningar Syftet var att undersöka användandet av kosttillskott bland 200 motionärer i Stockholm. Frågeställningarna löd enligt följande:Skiljer sig användandet av kosttillskott mellan män och kvinnor?Skiljer sig användandet av kosttillskott beroende på hur många gånger man tränar per vecka?Metod Studien baseras på en kvantitativ tvärsnittsstudie bestående av enkäter, där de tillfrågade bestod av motionärer i Stockholm. Enkäten innehöll; en kort förklaring till vad kosttillskott är, bakgrundsfrågor (kön, ålder, träningsform, träningsduration) samt frågor om kosttillskott (om man använder, vilken stort samt av vilken orsak). All data analyserades därefter i SPSS där vi använde både chi- 2 test och envägs ANOVA test.
