This essay will cover the Swedish electoral system with a focus on the proportional representation andthe process involved from the conversion of votes to seats in the parliament. This process consists ofseveral methods which are created by political decisions as well as mathematical formulas and is notalways perfect in terms of equalization. An increment of six adjustment seats would have made thegeneral election of 2010 more proportioned. Despite this, the Swedish electoral system is wellconstructed and the essay will highlight areas which could be subject for improvement as well asexplaining fundamental concepts of the process..

Safety and risk management currently have a starting point based on the negative outcome of safety, thus the lack of safety. The starting point for the thesis is to find a way to measure the positive outcome of safety through ergonomic aspects regarding chemical plants that are covered of the Seveso II Directive.Through a literature study of safety and ergonomics fourteen key aspects of safety were found. Safety Performance Indicators (SPI's) are used to assess the fourteen identified proactive indicators of safety. An analysis in three steps - called risk status assessment - is design to give an SPI its value. A pilot study of the risk status assessment was performed at the ethanol producer Lantmännen Agroetanol in Norrköping, Sweden..

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..

AbstractWith increasing population and increasing demands for comfort and thus an increase in energy demand, it is necessary to examine various energy-efficiency measures. This work deals with the ability to control the flow through the heating system to achieve the desired comfort with as little energy as possibleA heating system contains of different parts, roughly speaking, you can divide it to three main components: Heat source, Distribution and Heat emitters. All components are working together to bring heat to the building. What is examined in this report are different ways of adjusting the flow and supply temperature and how it affects comfort and energy use in a building.At today ?s date the conventional method is to use a high flow through the heating system, which affects pressure drop and cooling of the fluid.

Ergonomi innebär läran om människan i arbete, det vill säga samspelet mellan människa och arbetsredskap. Med detta som bakgrund kan man konstatera att det ställs höga krav på att arbetsstolen skall komplettera brukaren för att uppnå ett optimalt ergonomiskt sittande.Syftet med denna rapport är att ge en inblick i sittergonomi och utformningen av arbetsstolar. För att uppnå ett ergonomiskt sittande menar ergonomer att man skall sitta med en öppen höftvinkel, vilket leder till ett dynamiskt sittande. Det dynamiska sittandet gör att brukaren har ett rörligt och aktivt sittande. Detta kan till viss del uppnås genom ett sittande enligt principen för balansstolen.

This master thesis is commissioned by Permobil AB. The report describes thoroughly the developing process of an adjustable backrest for wheelchairs. The target group for the backrest are people that suffer from scoliosis or other spinal diseases. Because of insufficient pressure distribution usage of traditional backrests is not an option for them.The current solution has got a frame that is made by several adjustable links that is held in place by friction. Between the links velcro tapes are attached that is adjusts the depth.

Bath has been a part of human history for a long time. Today bathing/swimming inmunicipal pools is for people of all ages and it is possible to take swimming courses,exercise or enjoy recreation. The municipal indoor pool of Hogdalen in Sweden wasbuild in the sixties and has had problems with high levels of heterotrophic bacteria. Thefacility has two larger pools, one adventure park for young kids, two smaller bath tubsand a jacuzzi. To improve water quality UV light and coal filter were installed inOctober 2009 to the already existing purification system.

Together with Attends in Aneby a thesis of 15 ECTS (credits) have been undertaken. The assignment was to develop a new incontinence product for single use. Users of the product value comfort, flexibility, softness, comfort and a discreet product. Users are for individuals with incontinence problems that usually receive the products via prescription. The product must also have an attractive price and good quality from the purchase / originator's perspective.Currently there are two models that Attends supplies, which the project intends to develop, (Slips / Briefs and Pull On's).

Today we spend a lot of time at our place of work. Changes in the Swedish labour market have caused illness for many people. This has contributed to that many people have been reported sick. The purpose with this study was to investigate and deskribe factors the staff, at a social insurance office, identify as important for health at a place of work. Ten employees at the social insurance office took part in the study.

To invent an optimized product is a complicated process. This process is only half of the work. It is equally important to develop a production system that can produce the product in an  efficient and ergonomic way.After several evaluations of conceptual and detailed drawings a final idea has come to light.The idea intends, to the maximum extent, utilize the facility in a more efficient way through moving assembly lines and stations closer to the flock section and the stock for complete products. To make the production better, stations are placed in more logical places given the assignment they are supposed to accomplish. This improves the material flow radically.

Examensarbetet genomfördes åt företaget Corus Byggsystem AB. Ett företag placerat i Halmstad som tillverkar profilplåt och lättbalk till tak och fasader. Företaget erbjuder även god rådgivning och skapar optimala lösningar för kunden.I företagets produktion finns det en maskin som pressar specialbalkar. Denna arbetsplats är varken produktionseffektiv eller ergonomiskt riktig då materialet och balkarna lyftes manuellt, i vissa fall även över huvudet. På tunga arbetsplatser är det oerhört viktigt att se över ergonomin, både för att förbättra säkerheten och för att öka produktionsvolymen.

The project in question is a joint effort between students at Karlstad University and Marcus Norström at the company Hovercraft solutions. The project is divided into two parts, one focusing on the purely technical aspects of engineering the product and one focusing on the design aspects of the product development. The project described in this report is the design of the product. The assignment from Hovercraft solutions is regarding design engineering of a cabin for the hovercraft 380TD from the manufacturer Griffon hovercraft. The product lacks a cabin and none is offered from Griffon at the time being. 380TD is a relatively small hovercraft with a length of 6.8 metres and a width of 3.8 metres.The surface available for the cabin is not much different from the body of a car.Because of this, research has been focused primarily on car bodies.The product development process used in the project is following a systematic approach.From a chosen concept, the project was finalized with a CAD-modell as well as a detailed prototype.The weight target of 80 kg was reached and the ergonomic aspects were considered developing the sight field, roof- and entrance height.    .

Injuries and sick-leave is a common feature for reinforcement workers today. This is mainlydue to the fact that reinforcement work is done in an exposed environment with many stressfactors and highly repetitive work. These operations are often carried out in unsuitableworking positions, these positions creates a major burden on the bones and joints and causesmicro- damages on muscles. With repetitive work these injuries are not given time to healproperly and will gradually become worse.The body will not be able to handle the stress of working in a work environment such as thisand musculoskeletal disorders can be a result of this. The injury will make itself known aspain in the musculoskeletal system and causes reduced movability; the injured worker willtherefore not be able to perform the same work tasks as before.

This examination is about storyline and children who has problem to focus and concentrate in school. The premier aim of this survey is to look into the storylinemethod and investigate what it means methodical. I am also going to look more into how this children feels about this method and how they adjust to it.In my empirical examintion through qualitative interviews with teatchers and also questionnaires with thirtynine children participated i got a great result. My conclusions is that this method can be demanding and also confusing for this children but the good part is that it is subjectintegrated and it is easy to motivate this children.This examintation has given me an insight how teatchers can teatch in a storyline inspirated education.The storylinemethod is aiming to individual adjustment and these children maybe needs that moust of all..
