Light has always fascinated humans but ever since the invention of the first light bulb, the use of artificial lighting has accelerated dramatically. Darkness has never been as rare as today and the overuse of lighting has created a new phenomenon called light pollution. Most living beings are biologically dependent on the recurrent twenty-four-hour rhythm of light and darkness, called the circadian cycle. Human beings are evolutionary developed after this circadian rhythm and the effects of constant artificial light is yet unknown. Scientists fear the consequences of constant lighting and what it means physically, mentally and philosophically for the human species.

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.

This treatise analysis what functions light has in theater. It was inspired by Rosalinda Krauss essay Sculpture in the Expanded Field but builds mostly on the following three books Linda Essig Lighting and the design idea (2nd ed), Nigel H. Morgan Stage lighting for theater designers and Francis Reid The stage lighting handbook (6th ed). It discovers nine unique functions of light (performance style, dramatic style, image,illumination, 3D space, 3D form, selectivity, environment, atmosphere) and develops a graphical mapping of them based on a mapping by Reid. The functions performance style, dramatic style, image are superior the others.

In this study, we investigate various lighting applications in a virtual environment, where we compare between light based in naturalism (natural light) and pictorialism (artistic light). The purpose of this study is to gain further knowledge in lighting, which is increasingly important for game graphics. Theory are examined to gather information and recommendations on how to use various light settings that convey different emotions. We then use this information to illuminate the environment that we have built. The environment is presented in Unreal 4 for respondents who are allowed to move around freely in the environment.

The main aim of this master thesis was to examine the visual ergonomics and the systematic work environment management concerning lighting issues for nurses within domiciliary care. Further aims were to examine a few existing lighting solutions, to come up with ideas for future possible lighting solutions, and to evaluate if the legal regulations for lighting is satisfying and if the regulations are obeyed in domiciliary nursing.The methods used were a questionnaire completed by 55 nurses, field studies of used lightings in cooperation with a student in industrial esign, test of ten existing lighting solutions in a laboratory environment, and a field test of five existing lighting solutions tested by nine nurses in the home of the patient.The result indicates that 40 % of the asked nurses were dissatisfied with the working light in the patient?s homes. All respondents reported poor working light close to the patient, 50 % reported that this problem occurred daily. One third reported that they had to work in uncomfortable working postures due to insufficient working light, and 15 % reported risk of making mistakes due to the same reason.

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.

This project measures the upper bound of exposure time for laser reflection detection in the software DotDetector. Via measurement of the exposure time for which distortion happens in a room lit with everyday light we conclude that the upper bound for exposure times are 100 milliseconds. This value does not change as long as the lighting in the room is the same. As future work this project proposes variable upper bounds depending on secondary lighting in the room. Also we propose automating the colour masking of the detection algorithm..

The master thesis deals with three completely different areas: the place, the light and the design, which all are parts of the subject landscape architecture. The Place in this paper is the graveyard, the Light is the artificial and the Design is an illumination. The common denominator is the graveyard at Galärvarvet in Stockholm, Galärvarvskyrkogården, where the three parts meet in a clear and outspoken need of new lighting. The problem formulation is: Is it possible for a graveyard to be looked upon and used as a park? How do the administrators and the designers reason in this matter and what are the consequences for example the illumination at a graveyard? This is being investigated and discussed in general and thereafter the thesis is specifically focussed on the needs and solutions for the graveyard at Galärvarvet. The thesis, which is mainly based on facts from litterature, location studies and interviews, contains of pure parts of fact, discussion parts, different types of analyses, reflections of the author, illustrations and photos from the graveyard at Galärvarvet and also a lighting proposal for the graveyard and its close environment. The purpose of this work is to show the connection between the usage of the graveyard and its illumination. All to simplify for the administrators, planners and designers. Hopefully this thesis will be of use in the deciscion making process for future lighting projects for the graveyard administration in Stockholm as a basis for their discussion and decision process for future lighting projects..

The background to this report is based on how architectural art through timesbeen treating daylight with greatest precision to take advantage of its good quality,and how the technical revolution with artificial lighting affects our way of workingwith daylighting today.The purpose of the study is to contribute to the knowledge how the daylightopening affects the perception of a room. The aim is to clarify how proportionsand placement affects how the incident light occurs in the room and how thataffects on how the room is perceived. The study is meant to be used by lightingplanners, and in terms of pleasantness, be able to create the best possible daylightenvironment..

The purpose of this study was to develop recommendations for using more efficient lighting and better graphic design to create a more uniform structure in the exhibition hall ?Road to the past? in Jönköping County Museum by answering the following questions at issue:1) How are the objects in the exhibition hall ?Road to the past? exposed today?2) How can you use lighting and graphic design to create structure in the exhibition and strengthen the expression in the exhibition?Our work is based on observations and open group interviews. We observed the exhibition hall ?Road to the past? during day and evening. In the same hall, we observed a guided tour that we followed up with open group interviews.

This degree project has been performed on commission by Örsjöbelysning AB. The task has been to study alighting armature and compare it to the demands of The Swan Ecolabel. The task was also to recommend adjustments to improve the environmental adaption of the product to meet the demands of The Swan Ecolabel. Furthermore the task has been to gather documentation on the elements of the lighting armature. Such documentation is required to obtain The Swan Ecolabel.

Today all buildings contain some form of home automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home automation in singlefamilyhomes and to choose a suitable home automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.

This is a degree project that takes up history, present-day situation and analyzes these, that in turn becomes basis for cunning, both for shape and lighting, plus gives a eye-opener through entire the work. Vetlanda municipality acquires alter Stortorget that lies my in downtown. The area is not so used and has a fairly dreary appearance. Here are potential and a lot of possibilities for development. When working with a task as Vetlanda center, it is easy to take water over your head, so it is important to limit yourself. History, a description of today?s appearance and work area limit to the design proposal has been given different weight for the job.

During our education to become lighting designers at Jönköping University, the artificial lighting has been in focus. Therefore we wanted to learn more about daylight. We chose to do this from a visual approach in open plan offices. Since daylight is part of the architects´ responsibility to master, we wanted to examine what architects think of when they plan daylight environments in open plan offices and how this is expressed in the buildings with focus on the visual factors.Our questions at issue are:What knowledge do architects have concerning daylight planning, and how do they use this knowledge in their practice?How well do the chosen daylight environments meet the end-users need of a good visual environment? The study consists of three case studies, carried out in the same way.

I denna rapport konstrueras inledningsvis hyperreella tal från reella tal. Vi definierar aritmetik för skuggor av hyperreella tal och presenterar en icke-standard teori för serier och konvergens utifrån denna konstruktion.Förfarandet generaliseras sedan genom att skapa en icke-standard modell till matematisk analys utifrån en mängdteoretisk modell i ZF, som ett led i konstruktionen presenteras teori för filter och ultraprodukter. Vi visar sedan transferprincipen och bygger upp internalitetsbegreppet för att studera relationer mellan standard ochicke-standard modellerna för att kunna härledda standardresultat från icke-standard resultat. Avslutningsvistillämpas teorin för att skapa en explicit icke-standard konstruktion av Brownsk rörelse och vi ger ett bevis föratt denna konstruktion är ekvivalent med standard formuleringen..
