AbstractIn order to investigate whether people living in Linköping city feel that the built environment affects their exercise habits, a quantitative cross-sectional study with qualitative elements was conducted. A questionnaire was the chosen approach in which information about exercise habits, education level, built environment was requested. The selected group was people working at Skatteverket in Linköping where many people work and where age, gender and education level varies. The built environment does affect the exercise habits, where major proportions choose to exercise in areas considered inviting. The majority of the respondents had a tertiary education, and many lived in the city of Linköping.

Deferred shading är en renderingsteknik som har blivit allt mer populär i och med att hårdvaraukraven för tekniken inte längre är ett hinder. Ett problem med deferred shading är fortfarande hur transparenta objekt ska hanteras. Rapporten utvärderar två olika deferred pipelines som hanterar transparent geometri på olika sätt, de två renderingsmetoderna är Inferred Lighting samt Light Pre Pass med framåtrendering för hantering av transparent geometri..

The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.

My bachelor?s dissertation concerns the creation of a proposal for interior decoration of the Boland High School?s canteen. I have been in contact with personnel, students and the school principal through the duration of the project. In the end, substantive changes of lighting, interior decoration and movement were proposed for the canteen. In the proposal I have focused on accentuating the school?s profile, on creating smaller spatial configurations within the larger configuration of the room, lowering the noise level, creating a good movement flow, increase the number of seats and creating a pleasant environment in which to eat..

In this thesis is studied the electrical load of Paradisskolan with respect to power quality and energy consumption. The school's owner Trollhättans Tomt AB is also interested to know if they can reduce their costs by changing to smaller meter fuses. A recurring ground fault that?s been recorded from powerpanel A1A has been investigated. The school's equipped with an electrical bonding system, harmonic filters for the third harmonic currents, TN-S system from feeding transformer and groundfault monitoring.

Handling, loading, transport time and unloading in connection to transport of farm animals affect animal welfare. Induced effects include both psychological and physiological stress responses in animals. The physiological parameters may be measured through blood analysis while behavioural changes often manifest themselves through increased vocalisation, escape attempts and apathy. Physiological parameters are additional parameters of importance when measuring animal stress responses. The handlers behavior during transport has been shown to have major impact on animal welfare and the quality of meat. Animal friendly handling and driving of animals create a more manageable work environment for the handlers. To further increase animal welfare in connection to transport, stables should be built with well adapted drift passage and ramps on the transport vehicle.

Effektbelysning i trafikmiljö är ett nytt angreppssätt i strävan mot Nollvisionen, som är utgångspunkten för trafiksäkerhetsarbetet i Sverige. Upp emot 70 procent av de statliga belysningsanläggningarna har nått sin tekniska livslängd samtidigt som kraven på kombinationen av funktion, estetik och kvalitet har ökat i moderna belysningsanläggningar. Tidigare forskning beskriver ett samband mellan visuella kvaliteter och trafiksäkerhet och den här uppsatsen syftar till att undersöka hur gestaltning med effektbelysning i trafikmiljö kan öka trafiksäkerheten. Uppsatsen avgränsas till belysningsanläggningar i storskaliga trafikmiljöer och behandlar exempel på trafikplatser och vägbroar i Sverige och Danmark. För att få en bild av hur effektbelysningen gestaltats i dessa trafikmiljöer presenteras och undersöks befintliga belysningsanläggningar genom samtal med de involverade ljusdesignerna.

This thesis examines how to improve the exhibition of products within retail for clothes and gift articles. The purpose is to investigate and test how light sources and different directions of light affect how the products are perceived regarding their exhibition. Our question formulations are:To what degree does the level of light in combination with the background of the interior design of a shop affect whether a product is perceived more or less attractive?What can we recommend to make the exhibition of products more attractive? From our observations shops nowadays have relatively high levels of light when they expose products on vertical areas. We have looked on the recommendation from ?Energimyndigheten? in order to see what they think is important when designing retail lightening.

The report describes the thesis I, Philip Bergstrom, have done at the University of Gotland. The work comprises 15 credits and is at bachelor level and has been done in collaboration with Lyktan Bankeryd Belysning.The project consists of developing the design of a kitchen lamp for the Swedish home following the catchwords stripped French bistro that will fit into the Lyktan Bankeryd lighting spring collection 2013, and it should not look too alike any existing lamp on the market today.The work includes analysis of the company's current products and the image the company wants to project, analysis of three other companies' products to draw inspiration from, and a simple ergonomic study of the lights in the kitchen.The final result achieves the demands made and fits well in the intended environment, there is also the possibility for further development of both a floor lamp and a wall lamp..

Bakgrund: Kunderna inom armaturbranschen är idag mer involverade och konkurrensen för företagen är mer intensiv. Till följd av nya samarbetsformer har dessutom de enskilda leverantörerna förlorat möjligheten till direkt kontakt med slutkunden eftersom återförsäljare anlitas istället. Jobbet att kommunicera är därför mer krävande och svårhanterligt samtidigt som förutsättningen för leverantörens långsiktiga överlevnad är att de kan nå fram med sitt budskap.Problemformulering: Vilka värdeskapande samarbetsformer är viktiga för långsiktig överlevnad för armaturleverantörer?Syfte: Att mäta huruvida olika tillvägagångssätt av samarbetsformer och marknadsföringsstrategier påverkar armaturleverantörernas långsiktiga överlevnad. Metod: Undersökningen genomförs deduktivt där empirisk data samlas in med hjälp av metodtriangulering där både kvalitativa och kvantitativa metoder används.

Today's communication solution between the vehicle and trailer is one many see as anon-viable solution, then breakdowns on both the lights and cables are common. Now, anew innovation enters the market, a system that can transmit wireless control signalsbetween the vehicle and trailer.Parvus and Zap, the two solutions that the projekt group has come up with during thisthesis work carried out over the last year on Utvecklingsingenjörsprogrammet.Technologists Peter Jägevall and Christopher Åberg has developed this project on theirown. The group has developed various concepts and chosen to work on, two of them.The project has resulted in this report and a prototypeThe solution that the group has developed is a wireless communication between vehicleand trailer. The project team has developed new power-efficient LED lighting fixtures inorder to implement an internal power source in the trailer. The result of this has becomea maintenance-free and wireless product to trailers.

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..
