Fjärrvärme, vad annars? : Fjärrvärme och dess alternativ

AbstractBackgroundThe Swedish district heat market of today is a subject being discussed regarding the reasonableness of the heat district supplier?s price settings. The issue is currently on a government level where a new investigation is being executed at the time of writing. Many real estate owners are growing tired of the situation where the heat district suppliers are taking advantage of their monopoly position, thus feeling that the price of district heating has been increasing far too much for many years. The market can be described as a natural monopoly because the real estate owner has no possibility to choose another supplier if they are unsatisfied with the present.

Mekanisk integration av en IR-detektor i en Stirlingkylare

The master thesis ?Mechanical Integration of an IR-detector in a Micro Cooler? has beenperformed at FLIR Systems AB in Danderyd. FLIR Systems is a world leader in the design,manufacture and marketing of thermal imaging camera systems.The thesis project is divided into to two areas, Production Method and Noise.The Production Method concerns the positioning of a detector on the cold finger within the IRcamera.The detector has to be positiond with very high accuracy at the center of the cold finger,so it can be placed in line with the optical axis to avoid movement of the picture during zooming.The positioning of the detector is at present done with the help of specially designed guides on aplate on top of the cold finger. The design workes well but the special machining needed for thisplate is very expensive.The goal concerning the production method was to derive a new more cost effective method forthe assembling and positioning of the detector on the cold finger by replacing the guides on theplate with a reusable equipment or some other alignement operation.Several concept ideas have been generated with the help of concept generation methods in theform of concept classification trees and concept combinational tables. Two of these conceptswere selected to be further refined.

Ask the Library is a Swedish online reference service that is run by the country?s public libraries. The postmodern theories of Jean-François Lyotard are used to study how information is managed and transmitted within the service.

Utvärdering av simulatorer och emulatorer för inbyggda system

Uppdragsgivaren Saab Electronic Defence Systems i Jönköping erbjuder ett flertal produkter främst inom avioniksystem. För att kunna utvärdera och kontrollera produktens design i ett tidigt skede så kan en simulering av systemets beteende och att felsöka så tidigt som möjligt vara ett möjligt alternativ. En systemsimulering kan innebära att mjukvaruutveckling och felsökning kan påbörjas långt innan hårdvaruprototypen är tillgänglig, med samma storlek och komplexitet som systemet.Andra fördelar med simulering är att det går enklare att fastställa orsaken till systemkrasch, hitta de längsta exekveringstiderna och göra felinjiceringar. Syftet med detta examensarbete är att testa och utvärdera hur simulatorer och emulatorer är som utvecklings- och testverktyg.Rapporten innehåller en marknadsundersökning där tio stycken emulatorer och simulatorer hittades. Av dessa valdes två stycken ut, Wind River Simics och Imperas OVPSim.

Vi har i alla fall tipsbolag : En studie av möjligheterna att styra med belöningssystem inom kommunal verksamhet

Background: The use of reward systems can be of strategic importance as well as an affective mean of control for the organization in its work to achieve its goals. The municipal sector is characterized by its transparency and its responsibility for the taxpayer?s money. We therefore wonder which possibilities the municipal sector has to use reward systems as a men of control. Purpose: We intend to research the possibilities that the reward system offer as a mean of control for employees at the higher municipal level, with a special focus on commitment and motivation.

Contemporary Challenges of Public Pension Systems and Their Effects on Pension Reform Choices in European and Candidate countries

The process of European Integration and creation of the single market revealed many questions and boundaries on the development and improvement of the European Social Policy. Pension?s sustainability has become the priority issue especially during the EU enlargement processes. Different policy instruments and institutions available to governments of Member States in realization of social objectives resulted in a growing diversity of pension polices which produced different combinations of public and private provisions - ?private-public hybrids? , with the state exercising different degrees of influence in their development.

Har du tid? En studie av mellanchefers handlingsutrymme på Tetra Pak Dairy & Beverage Systems AB

Mellanchefer sitter idag på en position där de är tvungna att förhålla sig till ett stort antal faktorer som påverkar dem i deras arbete. Deras situation passar därför alldeles utmärkt för att undersöka aspekter som har med begreppet handlingsutrymme att göra. Vi har med hjälp av Tetra Pak Dairy & Beverage Systems AB tagit reda på vilka faktorer som påverkar deras mellanchefers handlingsutrymme. Detta gjordes genom att inledningsvis identifiera ett antal övergripande ämnesområden som ansågs påverka handlingsutrymmet i hög grad. Ämnesområdena fick sedan ligga till grund för de kvalitativa intervjuer vi använde oss av för att få in vårt empiriska material.

Användbarheten av två modeller i två olika företag, en studie av lean production : Fallstudier vid SKF Couplings systems och AQ Parkoprint

This study is about to see whether the two models representing the strategies of lean production is to use and apply in different companies. The models are structured in two different ways in which one of them is checking the softer elements of lean production in the form of leadership and strategies. This model is called Lesat and is based on interviewquestions. The second model, called "learning to see" is about identifying flows. This, together shall then give an idea of how mature companies are when it comes to a whole in the concept of lean production, and susceptibility to use these models to their respective companies. The study is conducted in two companies, SKF couplings systems and AQ parkoprint.

Självbild: påverkan och motståndskraft ur ett utvecklingsekologiskt perspektiv

Our paper is a study about youth and their self-images. During our practical training period we found that the problems young people had always were connected with their self-image. We therefore wanted to find out what youth believe influence their self-image. The purpose of our study was to examine young people and their self-images in a perspective of the ecological systems model. Essential issues have been what self-images young people have, what they consider influence their self-image most, how they think they can resist influence from the environment and how they would like to be influenced by the environment if they could decide themselves.

Solcellsdrivning av distribuerade inbyggda system

The high level of energy consumption that the industrialised countries have reached and thepollution that this brings has long been a cause for analysis and debate, development and usageof so called renewable energy sources is therefore more important than ever. The energy in theelectromagnetic radiation from the sun is an interesting alternative. One way of harvesting thisenergy is by using solar cells, devices that generate DC current when exposed to electromagneticradiation.The goal of this master?s thesis was to design a solar powered power supply to Syntronic AB?sMidrange platform. The envisioned application is a stand-alone distributed embedded system,for example a node-based temperature monitoring system.

Vad ridskolor lär ut om hästens beteende

The horses have been in the care of humans for about 5000-7000 years. But even though the horses have been domesticated and artificial selected for such a long time their natural behaviours and instincts still remains. In the rich countries there are many people who have the opportunity to ride either on their own horses or at riding schools. Many of these people have not grown up on farms and have no experience of handling big animals. This can lead to implications of the horses? welfare.

Adaptiv varvtalsstyrning vid användning av en lastbils kraftuttag

Med ett växande fokus på ett långsiktigt hållbart samhälle som tar ansvar för miljön strävar fordonstillverkare efter att sänka energiförbrukningen på sina fordon. Detta arbete behandlar hur man kan sänka bränsleförbrukningen för lastbilar med påbyggnader. En påbyggnad kan t.ex. vara en kran, en lastväxlare eller en betongpump. En metod för att sänka energiförbrukningen är att sänka det varvtal som lastbilens dieselmotor arbetar vid.
