This degree project was made in cooperation with AssiDomän Frövi and Charlotte Andersson and the main objectivehas been to create to ice cream pacbges from 250 gsm Frövi Light board. The paekages are intended to be easilyresealable while decreasing in size together with the ice cream. The project also describes the food packaging labelsand symbols currently present in the European common market.Both capsules utilize a separate lid for resealing. One of the paekages (Capsuie A) is indended to be cut along withthe ice cream and thereby decrease in size. The other one (Capsuie B) uses a series of flaps for contracting and expandingwhich enab1es adjusting of the size without cutting the package up.The design for Capsuie A is created both as a series of flavours with a super-hero theme intended for children andwith a colfee flavour for a maturer audience.

Today dairy farmers in Sweden are obligated to have lights turned on during night time in addition to the mandatory daylight inlet. This presents a cost for the production but many argue that it can be economically beneficial, especially in loose housing of dairy cows. In loose housing and even more so in herds with automatic milking, well functioning cow traffic during all hours of the day is crucial to optimise production. In order to keep the cow traffic flowing, lights may be an important management tool. It is also perceived among farmers with tied up stall that night light decreases the incidents of cows accidental stepping on their own or neighbours udders.

The aim of this study was to investigate the relationship between sleep, photoperiod, milk yield and hormones connected to milk formation. Variations of prolactin (PRL) and Insulin-Like growth factor-1 (IGF-1) in plasma were measured during two different light programs. The light programs consisted of either 24 hours of light (L24:D0) or four hours of light and 20 hours of darkness (L4:D20). Five cows of the Swedish Red breed were used in a cross-over experiment and each light program consisted of five days. Milk yield was measured at every milking and milk samples were analyzed with regard to fat, lactose and protein.

Discussing light and lighting in the night-time environment of Tensta, a Stockholm suburb built between 1962 and 1970, this thesis suggests that lighting should be designed for the outdoor environment as a whole. The feeling of safety and human perception are important components in this thesis. Starting with some comments on visual perception and how we adapt our sight to an interval of the visual input we get, makes it possible to understand that more light sometimes hides, rather than reveals, things. Amongst the dispersed houses, in the green parks of Tensta, this turns the pedestrian roads, lit by pole-top-mounted fixtures, into light tunnels in a dark surrounding. Talking about the feeling of safety I am inspired by, amongst others K. Lynch, B. Hjort and J.

To be examined in hospitals can sometimes be perceived aspainful by children. Therefore there is a need for something,which can distract children?s attention from their perceivedpain. During my graduation project, I discovered a designopportunity to work with suspended ceiling systems inexamination rooms, as there is not much to look at whilebeing examined.The result, Twig Ceiling is an interactive nature-inspiredbacklit module with colored LEDs. Twig Ceiling has onelayer of pattern that is visible when the module is not litand the second layer of pattern appears when turning onthe light.

Sleep is a vital part of life. Even so a lot of the mechanics regarding sleep is unknown. The dairy cattle of today live a stressful life, as their high milk yields forces them to eat large amounts of feed and spend a great portion of the day ruminating. Do they have time to get enough sleep? Which factors affecting the need of sleep in dairy cattle are largely un-known.

Bright Chest of DrawersThis project derives from a fascination of spaces which withonly light and shadow withhold a narrative value, which createsemotions and experiences with a minimum of objects. Iwanted to invesitigate light and lighting, and create a productthat can change the mood and experience of a spatial enviromentwith light. Questions I asked myself was: How do I relateto the spatial limitations that arise? How can I, with light asmy tool, give form to an immaterial value or state of mind?Will the object that illuminates be the most important factorof communication and meaning when I want to tell a story, oris it the light itself?The result became a chest of drawers that is lighted up frominside when you open the drawers. It serves a function as a unitfor storage of objects, but also makes us reflect of the importanceof objects, of how we define a spatial enviroment, andwhat we consider as private spaces in our home..

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.

The purpose of this thesis was to increase the understanding and discuss safety aspects in two stairwells on Nyforsgatan in Eskilstuna, where the buildings were built during the years 1965-1975. I have presented a proposal for improvement through lighting. I have through different methods, such as surveys, interviews, literature studies and observations, come to a conclusion: that there are opportunities for improvement through better lighting that allows orientation in space and creates a nice atmosphere which will remove the feeling of not being safe, e.g. dark corners and shadows. It has been an exciting process to gather enough of facts to rely on and to develop the lighting design for the environments.

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.

Use of lighting is crucial to make public urban places available during dark hours. Landscape architects participate in planning of lighting, but during our education there is very little taught on the subject. Through this study we approach the subject of lighting by looking into lighting methods for urban plant materials during winter. In this thesis we look into ways to emphasize the visible characters and experiences of urban plants during winter season using light. Target audience are landscape architect students and landscape architects without knowledge of lighting. The part of the thesis that describe basic conditions for, and visual characters of plants can be useful to lighting designers without knowledge in this subject. Working methods used were the following: ? Pre-study about light and lighting techniques through literature and dialogues. ? Compiling important visual winter plant characters through photography and literature. ? Outdoor light experiments with plants.

Lättelement located in Örnskoldsvik AB is one of Sweden's leading companies in the development of building elements in the form of roofs, walls and floors made ??out of light beams. The company has clients from Lund to Kiruna, and from Norway. This means that the elements have high standards when they have to take many different loads from wind and snow due to such wide geographic variation.The roof elements are structured so that the main body is made of light beams with an I?profile.

Då scenkomplexitet och ett högre antal ljuskällor blir vanligare inom spel har ett behov av algortimer för att hantera dessa scener, med bra prestanda, uppståt. En allt vanligare algoritm för detta är Deferred Shading. Rapporten utvärderar två olika metoder för Deferred Shading (traditionell Deferred Shading och Light pre-pass rendering)..
