FEM?modeller för expansionsanalys av piplines
REINERTSEN AS performs expansion and buckling analyses of pipelines using ANSYS, afinite element modelling and analysis tool. In an expansion analysis the pipeline is modelledwith thin?walled pipe elements called PIPE20 which allows plastic deformation. However, ina recent analysis the results retrieved from the PIPE20 element were incorrect for strainsabout 1 percent. One main issue was that the PIPE20 element overestimated the strains.The purpose with this Master Thesis was to become familiar with the theories and analysismethods used in pipeline design.

Konceptstudie av drivmodul till bandskotare med hybriddrift
BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.
Hur uppfattas pcSKOG AB och pcSKOG-gård av privata skogsägare? : en undersökning av en programvara för privatskogsbruket
pcSKOG-gård is a computerised manager plan for private forest owners, developed by the
pcSKOG AB. The program is based on forest stand data, joined with a map of the forest and
GIS-applications. The purpose is to offer a program for private forest owners managing the
forest and with the possibility of updating the actual status of the forest.
The company pcSKOG AB is the leading producer of programs for forest management and
has developed the program since 1997. The program is currently the most common program
used by private forest owners in Sweden.
The aim of this thesis, leading to MSc in forestry, is to investigate the purpose of the private forest owners when purchasing the pcSKOG-gård. The thesis also studies how private forest owners use the program, what they use it for and how the private forest owners state that the program has achieved to fulfil their expectations.
The thesis is also a market research concerning the knowledge and attitudes the private forest owners have about the program and associated services.
The study material has been collected during two phases.
Kognitionsforskning i djurhållningen: grisars kognition och dess tillämpning vid slaktsvinshållning
Pigs are often mentioned as relatively intelligent animals when compared to other nonhuman species. Despite this knowledge, the vast majority of pigs are kept under conditions that lack opportunities to satisfy their cognitive needs. Therefore, a need to evaluate the present scientific studies about pig cognition was acknowledged, in order to evaluate to what extent the knowledge is applied in the husbandry of finishing pigs. If a considerable lack of application was determined, suggestions about how to use the obtained information to improve pig welfare were also to be made.
A synthesis of the present literature was made, and it could be concluded that a considerable amount of studies had been carried out in the present area. The pigs of today appear to have the same behavioural and cognitive needs as their ancestor, the wild boar.

Inventering av bergborrade brunnar för dricksvatten i område med risk för salt grundvatten : en utredning av grundvattensituationen i Vreta-Ytternäs i Uppsala kommun
The city of Uppsala and its surroundings are a very expansive area. A prerequisite for a sustainable development of the area is well-functioning supply of drinking water. In Uppsala municipality, the Uppsala esker and Vattholma esker are the groundwater storages for drinking water. Besides the eskers, other sources of qualitative groundwater in the Uppsala municipality are relatively poor and more than half of the area consists of ground conditions with a risk of saline groundwater. The neighbourhood of Vreta-Ytternäs is situated 10 km south of Uppsala, in the area with risk of saline groundwater but outside the municipal water supply.
Regelstyrd 3D-projektering vid insättning av trappor i
trävolymer
Moelven Byggmodul AB är ett företag som arbetar med industriell tillverkning av volymbyggda trähus. En kritisk konstruktionsdel som utsätts för stora variationer mellan projekten är trappor. Ett projekteringsverktyg som underlättar arbetet med trappor skulle innebära att tidsödande arbete elimineras då de nuvarande arbetsmetoderna inte alltid är konsekventa. Under 2007 tog Sandberg fram en teoretisk demonstrator som i ord och bilder beskriver ett sådant projekteringsverktyg för trappor. Syftet med detta examensarbete har varit att undersöka om ett hjälpmedel för regelstyrd 3D-projektering vid insättning av trappor i en trävolym kan parametriseras i AutoCAD Architecture 2008 (ACA2008).
Mobilapplikationer som marknadsföringsverktyg för B2B? : En studie i mobilapplikationers inverkan på kundrelationer & kundvärde
Mobilapplikationer har på bara några år kommit att bli en naturlig del i marknadsföringsmixen för många företag som vänder sig till slutkonsumenter. Nu spås företagsapplikationer, mobilapplikationer skapade för företagsanvändare, stå inför sitt stora genombrott. Det verkar bland forskare och praktiker finns en allmänt utbredd åsikt om att mobilapplikationer har stor potential att bli en kraftfull B2B-marknadsföringskanal. Trots detta har mobilapplikationer ännu inte fått något omfattande genomslag inom B2B- sektorn och det råder stor osäkerhet kring hur de möjligheterna som mobilapplikationer har potential för ska tas tillvara.Syftet med den här uppsatsen är att försöka räta ut några av dessa frågetecken genom att utreda hur en mobilapplikation används som marknadsföringskanal av ett svensk B2B- företag, och utifrån detta undersöka mobilapplikationers potential som marknadsföringskanal utifrån två för B2B-marknadsföringsområdet centrala teoretiska perspektiv: relationsmarknadsföring och värdeskapande. För att kunna göra detta har vi genomfört en fallstudie av hur ett svenskt B2B- företag, ABB använder sig av mobilapplikationer i marknadsföringssyfte.
Hållfasthetsegenskaper i gjutjärn : tensile properties of cast iron
In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.
Cypern, EU:s halva medlemsstat
Since the 1st of May 2004 Cyprus is part of the European Union. The Republic of Cyprus as a whole is part of the Union, but all of the advantages of the Union membership cannot be enjoyed in all parts of the country. Since December 1963 the Cypriot administration has been separated into two, a Greek Cypriot and a Turkish Cypriot, and since 1974 the country is also territorially divided. The Greek Cypriot political administration is considered to be the legitimate representative of the Republic of Cyprus, the Turkish Cypriot administration is only recognised by Turkey. Since the disruption of the country in 1963 the UN has been trying to get the Cypriot parties to agree upon a peace solution in order to reunite the country.
Automatisering av flexibel fixtur
This thesis was conducted at Linköping University and SAAB Aerostructures, Linköping, and focuses on the automation of flexible fixturing in machining applications. At Linköping University a project called "Koofix" is conducted with support from Strategiska stiftelsen and several manufacturing industries including SAAB Aerostructures. The purpose of this project is to develop a more cost-effective, flexible, technique for fixation of workpieces during processing and assembly.Fixtures are an important part during the machining process, especially if you process the parts with high accuracy. Today a large number of fixtures are used at SAAB and they would prefer to reduce the number of fixtures by using flexible fixtures instead. SAAB uses one fixture for each article and this result in a high fixture cost and it also takes time to design and construct a new fixture.There are several advantages with using a flexible fixture such as that you can process workpieces with different length, height and thickness in the same fixture.
Utrustning för precisionsmätningar i 3D för undervattensapplikationer
WesDyne TRC är ett helägt dotterbolag till kärnkraftsteknologiföretaget Westinghouse Nuclear och arbetar främst med oförstörade provning och visuella inspektioner av reaktortankar. Inom kärnkraftsindustrin finns ett starkt intresse och behov av att kunna utföra noggranna geometriska uppmätningar inuti en reaktortank. I detta arbete utfördes först en förstudie där lämpliga tekniker undersöktes för att finna den mest lämpade för ändamålet. Den teknik som ansågs ha störst potential var aktiv triangulering med laser. Efter vidare fördjupning inom området utvecklades och konstruerades en prototyp med tillhörande programmering, som därefter testades och verifierades.
Tillståndsprövning - för lantbruk med djurhållning : en intervju undersökning med länsstyrelserna i Kalmar- och Hallands län.
The task of making a correct application for B- activities is the foundry time consuming
task. Information and facts concerning your entire business activity shall be attached into
a description of environmental consequences, which will be the basis for the decision
making whether the activities shall be granted a permission to practise environmentally
hazardous actions or not.
When the Environmental Act were established 1999, the permission process became
more extensor. With this study I want to give an insight about how these applications are
made. The methods I have used to collect information are a study literature where the
Environmental Act has been the focus, and qualitative interviews with two County
Administrative Board. I used the Environmental Act to understand why permission is
needed and the interviews to give me insight in how the work is done.
My conclusion is that it is very unusual that an application is granted without
complements.
