This report describes a project, which was carried out as a final thesis covering 30 ECTS during the final semester of the Master of Science programme Industrial Design. The assignment was issued by Fagerhults Belysning AB in Habo. The assignment was to design a family of products in which LED was to be used as a source of light. The main focus in the initial part of the project was to find a way to design the inside of armature which was suitable for LED technology. An armature, already in the range of products at Fagerhult, with the desired qualities that was to be strived after was the Zintra. The lighting source of the Zintra is a compact fluorescent lamp.

I den här uppsatsen undersökts hur greppet mise en abyme kan användas som ett dekonstruktivt verktyg i fiktionen. De tre romanerna som ligger till grund för uppsatsen är Montecore - en unik tiger av Jonas Hassen Khemiri, Sara Stridsbergs Drömfakulteten: tillägg till sexualteorin samt If on a Winter?s Night a Traveler av Italo Calvino.Gemensamt för romanerna är att de alla genom att kommentera sin egen tillkomst och låta boken uppträda i boken skapar en osäkerhet i frågan om vad som är sanning och inte i de respektive berättelserna. Sanningen rubbas och dekonstrueras om vartannat genom användandet av mise en abyme..

The purpose of this Master's thesis is to find possible explanations of variation in light scattering in a fine paper. Samples were collected from each second tambour during a time period of two weeks from a paper machine at MoDo Paper, Husum. Two data sets, consisting of 20 and 95 observations, were selected for extensive analysises of tensile and structual properties. The data was evaluated with multivariate data techniques using the programs Simca and Extract. The results of PCA- and PLS- analysises pointed out 3 of 52 variables as important for the variations in light scattering.

The urban heat island is an area restricted to a city center where the temperatureis higher than its surrounding environment. The greatest temperature difference isfound at night when the weather is calm and the sky is clear of clouds. There are twomajor causes behind this phenomena and the first one is the use of energy forheating of houses. The heat leaks through the walls of the buildings and warms upthe surrounding mass of air. The second one is the use of building material whichstore the suns radiation on daytime and releases the heat during night.

There are many different recommendations on how to keep pelargoniums over winter, but most of the recommendations suggest ?the higher the temperature, the more light and water the pelargonium needs?. The purpose with this paper is to try to explain the best and the worst results that are achieved with different storage alternatives of zonal pelargoniums. The results are based on an orientating investigation carried out in January-February, and a questionnaire that members of the Swedish Pelargonium Society answered to. Both the orientating investigation and the questionnaire showed that zonal pelargoniums are best stored light and cold but frost free. They should be irrigated according to their needs which is when the soil is dry, about every second to third week. Zonal pelargoniums are very resistant to drought and can survive without water for at least 44 days, both when kept under light and cold as well as under light and warm.

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 purpose of this study is to survey and evaluate if the individual contrast sensitivity and preferences for horizontal and vertical lighting level correspond to the values that standard SS-EN 12464-1 recommends for the workplace- and surrounding light levels.This study examines if lighting should be adapted after the individuals? need or if a general value can be found that will cover every individuals? need for a workplace and surrounding light level. This study also examines if parameters like sex, age and/or glasses/lenses have an effect on the amount of lighting that the test subjects need. Lastly we compared the values concerning the relationship between workplace- and surrounding light levels with standard SS-EN 12464-1?s recommendations.The study is carried out with an experimental design that surveys 220 test subjects who were chosen by a selection of convenience.

This report examines the prerequisites for LEDs to replace other technologies indifferent applications. How does the different technologies for light generationwork and what are the advantages and disadvantages? The various technologieslimitations and characteristics provides the opportunities for the LEDs.This report describes a test-construction built to examine what practical arrangementscan be built with modern light emitting diodes, in order to showsome of the possibilities. The construction consists of three different applications,a high power lamp based on cold white LEDs, one based on warm whiteLEDs for the evaluation of the light characteristics and a RGB-LED based lampable to mix any colors quickly and seamlessly. The test construction also containsthe essential peripherals including control-electronics, optics and a custombuilt watercooling solution.The potential for LEDs is huge but it is complicated to build LED based applicationsdue to the limitations which mainly includes the electronics and theneccesary cooling.

Animals in zoos live in more barren environments than their conspecifics in nature. In nature, elephants spend more than 75 % of the day foraging and have been observed lying down two hours during night. Stereotypies are common in many different species in zoos. Stereotypic behaviors may constitute up to 50 % of the daily activity budget of zoo elephants. Modern zoos try to reduce stereotypic behaviors by means of environmental enrichment.

To give a realistic impression in a driving simulator for nighttime driving, there are many challenging aspects to consider. One of the most important aspects is the illumination caused by the headlights of the own vehicle. To give a realistic impression there is the need to consider the characteristics of the headlight in use to be able to represent main and dipped beam, but also to represent different models and types of headlights. Another important aspect is the dazzling effects caused by the light cast by other vehicles upon the driver. These effects are not only important to give a realistic and visually appealing simulation, but also to simulate blinding effects which may affect the drivers ability to perceive the traffic environment to a large degree.

För att Swepart Transmission AB ska fortsätta att hålla en hög standard på produkter som levereras till kunder, ska monteringslinan för Power Take-Off säkras. Budgeten som är avsatt till att kvalitetssäkra monteringslinan är 500 000 kr. Pick-to-Light och Pick-to-Voice är system som kan användas för att kvalitetssäkra monteringen av Power Take-Off. Systemen jämfördes med systemet med monteringskort som används i nuläget. Det mest lämpliga att införa har visat sig vara Pick-to-Light.I samband med införandet av detta system måste utredningar göras för vilka komponenter som behöver sensorer och vilka som kan säkras på andra sätt.

This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.

In order to reduce the number of casualties and injured from accidents the rescue service must become more efficient and flexible. It is noted that far more people is injured and killed in traffic accidents than from fires. During the daytime the number of accidents in about three times higher than during the night, even so today the number of fire fighters on duty is the same day and night.Two computer models for simulation of different locations of the rescue services are used to determine the best options for placement of the rescue services. A cost-benefit analysis is also used to determine if today's fire stations are efficient for the society from an economical point of view.The results of the different models are that the fire station in Lund is misplaced. The number of ladders in Malmö can be reduced.

AbstractMy task was to prepare the already designed heating list ?Stayhot? for manufacturing.I started with drawing the whole list in the CAD-program. It became obvious that some of the designed components had to be changed to work in practice.A turnable reflector couldn?t be combined with the isolation. The suggested light emitting diodes wouldn?t give enough light, so I cut them out and the problem with light remains to be solved.

Gotland is an island with a rich history. One unique thing about it is the picturestones. There are, today, 565 known stones and fragments found on the island of various dating. The dating time spans from 400 ad to 1100 ad. This essay is meant to discuss the dating issue of the early picture stones dated to 400-700 ad and discuss the relevance and validity of the today?s dating.
