Användande av diffusionsspärr vid tilläggsisolering av äldre byggnader med trästomme

In the current situation a big part ofthe settlements that exist in Sweden isin need of renovation and energyefficiency in order to survive.Therefore, also many of the older houseswith a wooden structure are in a need ofenergy efficiency, which can be done ina variety of ways, including addinginsulation.This project deals with whether the useof a diffusion Barrier or a vaporBarrier affects a wall structure byadding insulation to an older house witha timber frame. The insulation materialswhich are concidered in thisinvestigation are mineral wool and woodfiber insulation. Efforts are focused onthe effects of moisture on theseinsulation materials.To demonstrate the differences thatarise the moisture measurement programWUFI have been used to simulate avariety of wall designs. These designsare developed in consultation with theconstruction carers who are active inthe industry.Using WUFI graphs illustrating themoisture levels of the wall structureswere obtained and from these conclusionsvould be drawn. The work demonstratesthe differences that arise when using adiffusion Barrier or vapor Barrier inwall construction.

Utformning av sidoområden med hänsyn till vägens livscykelkostnad

Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash Barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various Barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a Barrier and without a Barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside Barriers in use today. A mathematical model for calculating the life cycle costs of different Barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a Barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a Barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.

Bullertunneln : En utredning kring en ny bullerlösning vid trafikleder

The purpose of this Master Thesis has been to investigate the possibilities for a new type of noise reduction solution that could decrease the negative effects resulting from larger traffic roads. The idea has been to construct a noise Barrier with a roof ? like a tunnel placed on a road. The choice of material has been focused on transparent materials in order to lower visual intrusion and Barrier effects. This project idea is called the Noise tunnel.After having investigated the current offer of noise solutions, it has been concluded that these solutions rarely provide a sufficient level of noise reduction ? at least not when government regulations of acceptable noise levels are applied.

The Consumer as Barrier vs. The Consumer as Partner

First objective: To bring forward managers? perceptions of the underserved consumers in emerging markets. Second objective: To reveal what implications managers? perceptions of underserved consumers in emerging markets provide for branding in these markets. Our study indicates that managers? perceptions are still lacking consumer insights within five elements (value, loyalty, purchasing power, consumers and consumption).

Patent och företags storlek - finns det en tröskel till inträde?

Several studies have investigated the relationship between different measures of innovative activity, such as patent statistics and R&D expenditures and some have looked deeper into the differences between large and small firms regarding number of patents issued per employee or per R&D dollar. In this paper, the objective is to find out if there are any indications of a Barrier to entry (due to economical factors, lack of knowledge etc) for small firms to get into the field of patent handling. The approach is to first set up a hypothesis based on some simple assumptions about how firms would make decisions about whether to apply for a patent or not and thereafter use econometric methods in an empirical investigation. The data used for this study are figures on number of employees, number of patents granted and R&D expenditures for the Swedish firms in the pulp and paper industry. The main conclusion is that, based on the analysis of the data from this rather limited group of firms, no such Barrier can be seen..

Utveckling av programvara till ett inbyggt styrsystem

This thesis considers the development of the software for an, newly developed, embedded real-time control system, based on a Periferal Interface Controller (PIC). The control system is developed to be used for several different applications. In this thesis work, software for two different applications are developed. The first task is a time controlled system, while the other task is implementation of aPI-/PID-controller. A user interface is also developed and implemented.The time controlled system is an automatic horse feeder, which is used for feeding horses at certain predefined points in time.

?Tvärtom kan det gagna att vara bipolär. Kreativitet och sånt.? : - En kvalitativ studie om hinder och möjligheter för personer med ett psykiskt funktionshinder att komma ut på den reguljära arbetsmarknaden

Our aim of this study was to investigate Barriers and opportunities for people with mental disorders getting in to the labor market. This from experiences by people whose daily job contains work rehabilitation for this group in particular. On the basis of five qualitative interviews the results showed that prejudices towards people with mental disorders are a Barrier for them to get a wage labor. Furthermore the results showed that low self-esteem within the target group and also high educational demands becomes a Barrier to a wage labor. The results also showed that to focus on the healthy aspects may serve as an opportunity for people with mental disorders to get in to the labor market and be able to have a paid job.

Solel från ljudbarriär : längs Annetorpsvägen i Hyllie, Malmö

City of Malmö has ambitions for the district Hyllie to become a demonstrative area ofsustainable urban development. As a part of this the following report aims to investigate the potential in using noise Barriers combined with photovoltaics along Annetorpsvägen to generate solar electricity. To quantify the losses that shadows from buildings along the roadmight cause, a 3D-model of the area was constructed in SketchUp. This digital model made it possible to simulate shadows and how they change over the year. A reference model of a photovoltaic noise Barrier (PVNB) was constructed and used to find the dates on which the solar cells are shadowed depending on building heights and positioning of the Barrier.The results show that two lengths with a total distance of 400 meters is appropriate for applying photovoltaic noise Barriers.

Aim: The aim of the literature review was to describe how the nursing staff experienced their situation about their work with oral health in persons with psychical disabilities. Method: The study has been done as an overview and the data has been analysed with content analysis. Result: Two head categories were identified; Barrier that influence the ability to perform the work with oral health and Barrier that influence the performance of the work with oral health.

Hinder för fysisk aktivtet hos ungdomar i övre tonåren

AbstractEmilia Rönnberg.Barriers to physical activity in adolescents in their late teens. Vetenskaplig C- uppsats HT 12 Physical activity has been essential to human health and well-being since several thousand years. In Sweden, it has been shown that both adults and young people are less physically active than the rest of Europe- a large proportion of young people today do not meet the recommendations for physical activity (60 minutes per day). The purpose of this study was to determine what proportion of young people, i.e. high school students, did not meet the recommendations for physical activity.

Miljö- och kvalitetscertifiering som konkurrensfördel

Under senare tid har det på den svenska livsmedelsmarknaden växt olika miljö- och kvalitetsmärkningar som grundar sig på olika kriterier. Vi har i denna uppsats valt att studera två av dessa: Svenskt Sigill coh SVENSKODLAT. Syftet med denna uppsats är därför att ur ett producentperspektiv, undersöka huruvida Svenskt Sigill och SVENSKODLAT certifieringarna kan utgöra en strategisk konkurrensfördel. Vi har identifierat tre aspekter som var och en i varierande grad kan sägas bidra till att de båda certifieringar vi studerat skapar konkurrensfördelar. Dessa tre aspekter vilka vi sammanfattat i en ABC-modell är: adding value, Barrier to entry och cost saving.

Inträdes- och utträdesbarriärer : småföretagens rörlighet på den gotländska bankmarknaden

The main purpose of this study was to investigate which enter- and exit Barriers that exist on the banking market for small enterprises located within the region of Gotland. The reason was to examine and identify which Barriers that could affect the mobility among small enterprise bank customers on the bank market. To identify the Barriers, the study was carried out partly by a quantitative survey with 33 small business owners respondents located at three different concentrated small enterprise areas within the region of Gotland. And partly by qualitative interviews that were conducted with two employees at Länsförsäkringar Gotland Bank.The result indicated that the enter Barrier mostly depended on the aspect that business owners of small enterprises believed that bank switching were complicated. The business owners did also consider bank switching as time demanding.
