HiGtech är en projektgrupp på Högskolan i Gävle vilka konstruerar och bygger energisnåla tävlingsfordon. Ett av fordonen tävlar i Shell Eco Marathons prototypklass för bensindrivna förbränningsmotorer och drivs av en på högskolan konstruerad motor. Motorns effekt överförs till en kedjetransmission via en inköpt och modifierad centrifugalkoppling. Den nuvarande centrifugalkopplingen väger cirka 1,5 kg. Då en stor faktor för tävlingsresultatet är fordonets rullmotstånd, vilken beror av fordonets vikt, har målet med detta arbete varit att konstruera en specialanpassad centrifugalkoppling, vars vikt endast är hälften så stor som motorns nuvarande koppling.

We have chosen to write our essay in collaboration with Varbergs kommun, where our starting point is to improve energy efficiency by management control. Their occupation separates from a pure profit driven corporation and therefore the management controls have to be adapted accordingly.  The reason why we have chosen to write an essay about the management control opportunities to improve the energy efficiency depends on two different reasons. The first reason is that we find it very interesting, how with support from the management control it is possible to improve different parts of the operation. And the second reason is that Varbergs kommun expressed a wish that they wanted to improve their energy efficiency process.The purpose of the essay is to describe and analyze the opportunities with support from the management control to help improving the process of energy efficiency in a municipal operation.

Here materials and products behaviour are tested and evaluated, being exposed to fire. For this task, UGNET is being used for control and surveillance of the testing furnace system. System hardware has been updated gradually through the years, while the software has been neglected.

This paper is a study and comparison between the two Wireless LAN (WLAN) standards HiperLAN/2 and IEEE 802.11a. WLANs are used instead or together with ordinary LANs to increase mobility in for example an office. HiperLAN/2 is an European standard developed by ETSI and the IEEEs standard is American. A WLAN-card consists roughly of a Medium Access Control (MAC), Physichal layer (PHY) and an antenna. The antenna is the same for the different standards.

Bakgrund och problemdiskussion: Under årens gång har det inträffat flera företagsskandaler. Det har sett bra ut på ytan men insidan har visat motsatsen. Fasaden kollapsar till följd av bristande kontroll. Intern styrning och kontroll och COSO:s Internal Controll ? Integrated Framework blir allt mer aktuellt för att få ordning och reda.

Hunden är människans bästa vän, men det är först på senare tid som hundens hälsoeffekter har börjat undersökas. Internationellt sätt används hundar i vården i en helt annan utsträckning än i Sverige. Hälsoeffekter i form av kortare vårdtid, snabbare rehabilitering och bättre egenvård har påvisats. Syftet med litteraturstudien var att beskriva patientens upplevelser av hundens närvaro i vårdandet. Studien var en litteraturstudie med 15 vetenskapliga artiklar.

If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.

The aim of the study was to understand professionals? perceptions and experiences of adolescent stress. In the study I interested myself further if you can identify gender-specific patterns in the professional stories about young people's stress and stress related illness. Five interviews were conducted with professionals in psychiatry and social work. The thesis took its incipience in social constructionism.

The demand for shorter lead-times and increased delivery reliability puts pressure on companies to provide more efficient logistic services. One strategy to deal with this demand is by outsourcing logistics to a third part. The development of logistics information systems enables increased control over business supply chains. This is why Green Cargo aims to create a Logistics Control Tower (LCT) solution to provide it?s customers with better information with higher availability.

The purpose of the study was to investigate how inventories of suspected polluted areas as a part of the planned control of existing companies cab be designed in order to achieve as great effect as possible. The study was conducted in cooperation with Piteå municipality. An analysis of regional inventory projects, local municipal strategies and a pilot study in Piteå was conducted. The experience from both the regional projects and the pilot study was that in order to achieve an effective control a number of factors were inportant: an efficient selection of companies, a good dialogue between the controlling agency and the companies, sufficient resources, education of municipal inspectors and guidance for decisionmaking. Another inportant result was that the municipal planning can prevent an efficient inventory if the control of city development projects is allowed to take time from the planned control.

Under de senaste åren har fetma ökat, 14% beräknas lida av fetma i dagens svenska samhälle. Många har gjort ett flertal viktminskningsförsök utan bestående resultat. Bariatrisk kirurgi är det som enligt forskning ger bäst viktminskningsresultat. Acceptance and commitment therapy (ACT) har tidigare visat sig vara effektiv i jämförelse med treatment as usual. Den här studien utforskar graden av terapeutstöd av ACT-baserad internetbehandling efter bariatrisk kirurgi vid en två-årsuppföljning.

This essay examines the differences between the mediation practices concering youth crime in the swedish cities of Kalmar and Växjö. The analysis are made with the use of quality interviews which we have linked together with the three theories of Social Control Theory, Restorative Justice and Transformative Mediation. There after we have compared the results with one and another. Results show that there both similarities and differences, both in the theoretical aspects and in the organisations, for example the coopiration with the prosecutors and the police..

The engine of JAS 39 Gripen, RM12, has recently been equipped with a new flameholder and a new engine inlet. This change has caused an increased noise level from the engine when the afterburner is in use. The noise level reaches its peak when the afterburner is partially used. The problem is thought to be unstable combustion in the regions around the flameholder. A solution to the problem has been proposed by Volvo Aero.

Today, "the digital library" is the common way of describing a managed collection of information, with associated services, stored in digital formats and accessible over a network. Digital libraries have mainly been developed at research libraries, but during the last few years public libraries have started to offer similar services.The aim of this Master's thesis is to study how the Swedish public libraries plan to develop their digital libraries according to their mission statements, and in what way they have implemented them at their web sites. 21 public libraries, the largest in each Swedish county, were investigated.The library mission statements are investigated to find out in what terms the digital libraries are described and to what extent. The library websites are examined with respect to what kind of digital services are offered, to what extent they supplement or replace the physical library, and if there are new digital services not found in the physical library.In most mission statements the digital library is referred to in sweeping terms like "IT activities" and "new media". However, a few of the libraries clearly regard the digital library as an important part of the future operations, speaking of it in well defined and extensive terms.The public library websites are relatively homogeneous when it comes to services supplementing physical library activities, like web access to the library catalogue and links to other library catalogues.

Mechanical ventilation is the most common type ofventilation in newly constructed office buildings. Therehas been an interest to utilize natural ventilationinstead of mechanical ventilation among architects andHVAC consultants in recent years. This is due to thesize of mechanical ventilation systems, which arespace consuming. The mechanical ventilation system isalso complex and requires maintenance. Furthermore,the fan uses a considerable amount of energy.
