ABSTRACTThis project thesis has been written at the request of Mälardalens University, Västerås.The aeronautical engineering students at Mälardalens University and the pupils of Hässlö upper secondary school, all gets the opportunity to perform a computation lab with a real turbojet engine during their study. The goal of the lab from the University is that it should give the students applied experience from the theory part of which has been tought in the course ?Aircraft Engine Technology?.                      The pupils of the Hässlö upper secondary school are performing simpler calculations from the measured values of the equipment. This turbojet engine is located at Hässlö airport in the premises of Hässlö upper seconday school.Since the installation 1989, the engine has lost both thrust and reliability. This makes the theoretical computations made by the students inaccurate.

Genom den rådande utvecklingen inom svensk rundvirkeförsörjning, som går mot större och färre produktionsanläggningar, blir medeltransportavståndet allt längre. Detta ökar behovet av järnvägstransporter av virke och förändrar därmed de andelar som bil- och järnvägstransporter utgör av den totala virkesförsörjningen. Ytterligare påverkan på transportval åstadkoms av varierande järnvägsnät och industriplacering i förhållande till detta. Syftet med denna studie var att utveckla en simuleringsmodell för att kartlägga effekterna av systemkonfiguration och omvärldsfaktorer på leveransprecision, lagernivåer och ledtider i massavedsförsörjning. Metoden som användes var objektorienterad händelsestyrd simulering i kombination med linjärprogrammering. Styrningslogiken som användes baserades på systemstatus och tog beslut om allokering av transportresurser genom justerad schemaläggning av tåg, anpassningar i biltransporternas totala kapacitet samt omstyrning av flöden mellan industrier. Två system användes, baserade på järnvägens struktur för norra respektive södra Sverige.

Independent schools are a central issue in the school world, the perception of independent schools varies and many people express opinions about them in the media. An independent school is according to the National Agency a school that has a different principal than the county or municipality. Independent schools may not charge fees but their revenue comes from municipal grants from municipalities (Berglund 2007, p. 10). An independent school can be driven by an association, foundation or company and to run an independent school requires a permit from the Education Department.The purpose of this paper is to see how four principals at independent schools with a Muslim profile are working to strengthen their students? Muslim identity in relation to the society they live in and how schools work with value issues.

Under de senaste åren har sågverksindustrin påverkats starkt av det som närmast beskrivs som en finanskris. De rådande förhållandena ställer höga krav på sågverksföretagen och för överlevnad krävs ekonomisk uthållighet, effektiv produktion och hög grad av kostnadsmedvetenhet. AB Karl Hedin har haft en positiv utveckling, men som många andra företag i sågverksbranschen arbetar AB Karl Hedin ständigt mot effektivare produktion och ökad lönsamhet. En faktor för ökad lönsamhet kan vara förbättrat råvaruutnyttjande. Efter en lång tid med högt marknadsfokus ser därför AB Karl Hedin i Krylbo ett behov av att öka fokus på förbättrat sågutbyte.

The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

The abrupt and early weaning of intensively kept lambs may have serious animal welfare implications, but relatively little is known about this. Weaning includes the breaking of the mother-young bond and abrupt replacement of milk by solid food, often coinciding with changes in the (social) environment. Altogether, these changes are likely to affect lamb welfare significantly. This study aimed to establish how strong and persistent lamb welfare is impaired following abrupt weaning by means of measuring behaviour parameters indicative of affective state. Also, we investigated the existence of a diurnal rhythm in play behaviour, which is considered an important indicator of positive affect and good welfare.

We are heading towards a huge switch of how energy is produced with fossil fuels being replaced by renewable energy sources. It is not difficult to replace the energy you use in the house and there is no need for futuristic technology. There are already many established products on the market such as high efficiency vacuum solar collectors, heat pumps & small wind power stations that can supply the energy being used in a house. The company Sol & Energiteknik SE AB in Huskvarna has many different products which can reduce the need for an outside energy distributor. An average house in Sweden uses 15 000 kWh for heating, 5000 kWh for tap water and 5000 kWh for electricity.

This report has been performed for WSP Construction Design located at Arenavägen 7 in Stockholm. WSP Construction Design is one of the leading departments in Sweden in construction solutions regarding everything from building construction to industrial building. Great competencies regarding steel, wood and concrete constructions are available within the department which is well sought.Crane girders used in the industry are exposed to large loads that vary over time that includes instantaneous lifts and the crane girders movement which lead to the phenomenon fatigue in the crane girder and its ingoing welds. A control of fatigue needs to be performed after a certain lifespan measured in time which in turn is converted to a number of loadcycles. When the number of loadcycles amounts to a greater number the input welds resistance will have been reduced and the rate of utilization thereby increased.

Boulognerskogen is a park in the central of Skövde that have had a health resort, paths for strolling, outdoor-bath, outdoor-sport areas and events. During the 1970:th there was a lack of interest for the park and very few visited it. By a motion from a resident in Skövde wich proposes that a city playground will be build in Boulognerskogen gave me an opportunity to investigate how the potential of the park can be used to create a funny and nice place to visit for children in company with adults. By a program that contains the main goals and design program for a city playground in Boulognerskogen, I wanted to present a proposal that could meet childrens needs to play and to use the conditions of the place to create places to play in, and where children in company with adults could be together. To reach this, I wanted to try different methods that could lead to a proposal that was well supported by children and adults, and wich was possible to use by the local authority in their further actions. The methods that I used was therefor an important part of the work. I have choosen to define the concept "city playground" as a greater playground situated in the center of the town that are suitable for outings and as a meetingplace, with a varation in playground attractions and promote children and adults to be together, aiming at younger children in the ages of 1-10 years in company with adults, but should also give space to activities of other groups.

Sweden has today the highest moose (Alces alces) population in the world. The population has been very high since the late seventies and in the beginning of the eighties there was a big ?moose explosion?. The main food source for moose during the winter is young pine (Pinus sylvestris) and birch (Betula spp.). The high moose population has therefore lead to high damage on pine forests over big areas.

SCA har idag cirka 280 000 hektar beskogad med contortatall (Pinus contorta Dougl. ex Loud. var. latifolia Engelm). Stora delar av den arealen har kommit in i, eller är på väg in i, gallringsbar ålder.

The buying decision process describes how the consumer makes a purchase decision through a rational process (Markin, 1979) and an understanding for how consumers make a purchase decision can according to Sands et al. (2010) be obtained by increased knowledge for the information search process (the second part of the buying decision process) before a purchase. Today?s society offers great opportunity to obtain information (Rahim & Clemens, 2012; Bawden & Robinson, 2009) and by that there are in other words good opportunities for a rational acting by the consumers. However, there are factors working against that consumers act rationally and seek information prior to their purchases primarily in the form of the concept of information overload (Bawden & Robinson, 2009) which claims that consumers are limited in their information search because there is too much information but also other factors such as lack of time (Wood & Neal, 2009) and ability to find information (Slegers et al.

The market for security is one filled with great opportunities. The security services companies are numerous and diverse, the Swedish market is dominated by two large companies: Securitas Bevakning AB and Falck Security AB. In this study we have focused on the bigger of the two, Securitas. This report describes and analysis the security service branch and its surroundings in an involved manner. The target group of the result is mainly people within the security branch.

Sitka spruce (Picea sitchensis (Bong.) Carr) is just like Norway spruce (Picea abies) a species in thegenus picea. The natural range of Sitka spruce is a narrow strip along the west coast of North America. Itis the most coastal of all picea species, and very dependent on the mild and humid climate along thepacific coast.Sitka spruce has been grown a long time in the countries around the North Sea, particularly in GreatBritain where it currently is the most important species in British forestry. Sitka spruce has not beenplanted in Swedish forests to any large extent before the storm Gudrun in 2005. Several studies indicatethat the production of wood biomass is higher for Sitka spruce compared to Norway spruce.
