This work is an experimental study where knock sensor placements are investigated using engine tests. The aim is to studythe quality of the signal from knock sensors and how the signal for engine control is affected at different sensor locations on Scanias, engine DC13. To find out at witch position on the engine youcan get a usable signal for engine control, the engine is running while the knock sensors with advanced measurement equipment is connected to the engine. Evaluation of signals from the knock sensors are made in the computer program Matlab. The program is producing a seriesof plots, from these plots it is visually possible to draw conclusions and find connections.

Abstract The purpose of this project is to develop a modular processor card which is intended to work as a platform for Kitron Development Karlskoga. The modular processor card is meant to be used as a control system in development projects, mainly in medical and industrial products. The processor card will consist of a central unit with the basic functions for a control system. Furthermore there will be complete modules with machine commodity and programming, to pick exactly the necessary functions for a specific application. With consideration to the specification of the development and the main unit, I chose an adequate microprocessor (AT90CAN32) as core and interface circuits to stated border areas. The construction is first completed in the program MultiSim and then remade in the program OrCAD Capture. The programming language C was used in the software model.

Inom förskolan finns många barn med ?störande? beteenden och förskollärare möter någon gång dessa barn. Syftet med denna studie var att undersöka hur förskollärare kan arbeta för att skapa en optimal lärandemiljö, både ur ett pedagogiskt och ur ett socialt perspektiv, för dessa barn. I studien kommer begreppet beteendeproblem, utifrån Socialstyrelsens (2010) benämning, att användas.Första delen av studien består av litteraturstudier. Nordahl, Sørlie, Manger och Tveit (2007) påvisar vikten av proaktiva strategier för att förebygga att beteendeproblem uppstår eller att existerande beteendeproblem förvärras.Den andra delen av undersökningen består av sju intervjuer med förskollärare.

During the last decade, the construction industry has focused on improving and optimising its production process. The construction industry is now facing larger changes regarding efficiency in their supply chain for the next decade. Many companies are now trying to optimise its supply chain together with its supplier. JM AB, which is one of the biggest construction companies in Sweden, is looking at different options to improve its own logistics together with their suppliers. One option is to use a terminal between JM and the suppliers to solve problems such as quality, custom service and inventory for the in production.

Fire is an important ecological factor, but its consumption of coarse woody debris, CWD, has hardly received any attention. In this study, I investigate the consumption in relation to the time of initial flame exposure and propensity for continued combustion of standing CWD of pine (Pinus sylvestris). Two types of CWD were studied. Firstly, wood that had been dead for one to ten years. Secondly, wood that had been dead for several decades. In the burning experiments, logs of approx.

This study focuses the gendered relations of the Military Academy of Karlberg. More specific the study is investigating the experiences among young women and men cadets of suppression techniques. The purpose of the study is to get more knowledge about the work climate and suppression techniques at the officers? training program 2007/2010. The research questions employed for the study were:- Do the women and men officer students/cadets have any experiences of master suppressiontechniques at the officers? training program?- What kind of master suppression techniques occur at the officer?s training program?- What kind of master suppression techniques do women experience?- What kind of master suppression techniques do men experience?The study is a survey and data were retrieved by a questionnaire sent out to the participants.

Examensarbete som bestod i att rita en låg- och mellanstadieskola i det nybyggda området Annedal. Skolan är programmerad för cirka 600 elever, sex årskurser med fyra klasser i varje årskurs, 25 elever i varje klass. Utöver de olika klassrummens hemklassrum breddades skolans program genom att låta specialklassrummen (slöjdsalar, idrottshall, mm) rita sig utåt och bli offentliga lokaler efter skoltid. Skolans program består alltså av 24 klassrum med tillhörande hemvister, två musiksalar, sal för träslöjd, sal för syslöjd, bibliotek, fullskalig idrottshall med fyra tillhörande omklädningsrum, en aula som rymmer hela skolan samt andra mer serviceinriktade skollokaler såsom matsal, skolkök och kontor för skolans administration.För att ta sig an skolans stora program användes en metod där skolan fick komma till som i ett collage. Olika väl fungerande rumsligheter från andra projekt blev inspirationskällor som införlivades och fogades in i byggnaden.Tanken om collaget blev även vägledande i utformningen av byggnadens estetik samt dess tekniska detaljer.

The aim of this study was to get a deeper understanding of how employees at NCC Construction Sverige AB experience health promotion activities. The purpose was to identify and uncover the process of meaning constitution concerning health promotion within each subjective individual. To achieve this deeper understanding the participants were asked to answer a carefully formulated phenomenological question in a self-report. The received reports where analysed according to the method of Meaning Constitution Analysis. The result showed that both office workers and construction workers exclusively refer health promotion to bodily functions even though there where some differences in type of activity they focused.

The aim of this study was to investigate the relationship between sleep, photoperiod, milk yield and hormones connected to milk formation. Variations of prolactin (PRL) and Insulin-Like growth factor-1 (IGF-1) in plasma were measured during two different light programs. The light programs consisted of either 24 hours of light (L24:D0) or four hours of light and 20 hours of darkness (L4:D20). Five cows of the Swedish Red breed were used in a cross-over experiment and each light program consisted of five days. Milk yield was measured at every milking and milk samples were analyzed with regard to fat, lactose and protein.

The Landscape Architecture Program at SLU, Ultuna provide several design courses. Within these courses, students are mainly introduced to one type of design process, a process based on the specific site and its conditions, known as Genius Loci. This report presents a course and a design methodology from Cornell University which aims to provide students with tools for a more conceptual way of thinking about design and architecture. The design method is presented in two stages. First an introduction to the course description and objectives.

AbstractIn urban societies people spend more and more time indoors, which put great demands on the indoor environment. If the ventilation is to manage the removal of unwanted substances in the indoor air, a good mixing of the air is required. The question arises that, whether the buoyancy forces will counteract a good mixing of the indoor air or not?This report aims to clear up the difficulties whether you need to consider the buoyancy forces or not, when adjusting a ventilation unit. For studying the indoor mixing of the air a two dimensional model is constructed in COMSOL Multiphysics.

In East Africa live two species of Griffon Vultures; Rüppel?s Griffon Vulture (Gyps rueppellii) and African White-backed Griffon Vulture (G. africanus). One of the apparently most important factors limiting the population of these birds is food supply. Griffon vultures nest for eight months of the year, and are during this period geographically tied down to the nesting place.

Costs of maintenance on agriculture machines is something that many farmers has a low knowledge of, it can depend on low interest or that the farmer don?t have enough time. To make it easier for the farmers they can use many computer programs which are available on the market. In this program they can calculate their costs of maintaince on their agriculture machines, for example STANK and JTI machine calculation program. Most of this program is using Svensson (1987) costs model whish was made in Sweden in the middle of 80 decade in a large study.

Anledningen till att jag valde att skriva om valet till gymnasiet är att jag blev nyfiken på vad som påverkar elevernas beslut och vad det är som tilll slut gör att de väljer som de gör. Nyfikenheten uppkom efter att jag själv varit i valet och kvalet när jag skulle välja program på gymnasiet. Mitt syfte är att genom en enkätundersökning och efterföljande intervjuer försöka få vetskap om vad som påverkar elevernas val till gymnasiet. Jag vill även försöka undersöka överhuvudtaget varför man väljer som man väljer. Jag har valt att koncentrera mig extra på det Naturvetenskapliga programmet och är därmed nyfiken på vad högstadieeleverna tror krävs av dem som väljer detta program.Jag vill även ta reda på vad för slags information om detta program man fått och från vem denna har kommit.

Sweden is the country that has got the largest amount of elderly in the adult population in the world. The physical activity level decreases as we grow old and we experience muscle mass loss and a bone density reduction. This leads to an increased risk for falls and subsequent fractures. The purpose of this study was to investigate whether an exercise program could affect muscle function and balance ability to prevent falls. 17 women (age 64-79) participated in this study and was assigned to a control group (n=7) and an intervention group (n=10).
