Islastens inverkan på brottsannolikheten för glidning och stjälpning av betongdammar
There are many old dams in Sweden and, since few dams are constructed today, the main task in risk assessment on the existing dams is often to reduce the risk of failure. RIDAS (Swedish Guidelines on Dam Safety) is used when designing new dams and assess the existing ones. The guidelines include stability requirements for different failure modes, e.g. overturning and sliding, which imply that the load effect from e.g. uplift and ice load need to be less than the resisting loads or moments.
Flexibel utemöbel
Att produktion sker med hänsyn till människa och natur är viktigt för möbelföretaget KLONG. Detta har gett till följd att en ny kollektion av möbler utvecklats med fokus på knock-down. Vilket innebär att produkten är anpassad och konstruerad på ett sådant sätt att möbeln går att plocka isär och sammansättningen av produkten kan ske så nära slutkonsument som möjligt.Dessa produktionsförändringar får inte påverka produkten negativt så den förlorar sin identitet, möbelns formspråk ska uttrycka KLONG.Mitt arbete avser ett projekt där utemöbler har utvecklats åt KLONG utifrån krav på bl.a. produktion, distribution och funktion.Projektet påbörjades genom att utföra en grundlig analys av KLONG och deras produkter. Därefter utvecklades via designprocessen en flexibel knock-down möbel som via sin design förmedlar KLONG samt uppfyller sin funktion och innehar miljösmart distribution och tillverkning. .
Kontrollsystem för implementering av en samhällsansvarsstrategi - En undersökning av SPP Livförsäkring AB
Corporate responsibility is a popular phenomenon of today. The interest for the subject is extensive and means for implementing corporate responsibility strategies within organizations are demanded. There are studies showing how management control systems can be used in order to implement general strategies into organizations. Still, management control systems designed for the implementation of corporate responsibility strategies, in particular, are not provided by the current academia. The aim of this paper is to contribute to studies within management control systems by studying the management control system specifically designed to implement corporate responsibility strategies.
Ekonomiska styrmedel för förpackningsavfall : En studie om vad som påverkar återvinningen i EU
In 1994 the EU directive of packaging waste was adopted. The result was that all EU member states developed different systems to manage packaging waste and recycling. This paper examines the various systems and the factors that affect the level of recycling. This is done by a cross-sectional study between countries. The results of my study suggest that take-back system generates less recycling than other systems, the mandatory deposit system can affect the recycling in a positive way.
Styrelsens användning av styrmedel -en jämförelse mellan entreprenöriella och icke-entreprenöriella företag
Management control systems are a popular area of research and a lot of new research has been done over the past years. This development has been looking into new situations and circumstances, and interdisciplinary studies are being made to further understand the connection between different fields of study. A new field of study that has grown significantly over the past few years is the connection between management control systems and entrepreneurship. Leading researchers have proposed a number of questions for further research and one of them is the board of directors? use of management control systems in entrepreneurial firms.The purpose of this study was to examine the differences and similarities in the board of directors? use of management control systems between entrepreneurial and non-entrepreneurial firms.The study was conducted as a deductive qualitative study through interviews with respondents from entrepreneurial and non-entrepreneurial firms.
Att testa kvalitet : En validerande informationsinsamlingsmetod för ökad kunskapsåterföring
This master thesis has been carried out at Scania R&D at the department for Powertrain Control System Development during the winter of 2010/2011. In the thesis the writer examine and evaluate the existing method for collecting information from the tests carried out during the development of the Powertrain Control Systems software. It also contains suggestions for how a new method that enhance the validation elements could look like.The master thesis uses Vicentes theories of the ecological approach and theories of how knowledge sharing of tacit and technical information works within an organization and between the organization and its customers. First a workplace analysis at Scania R&D is carried out to see how Powertrain Control Systems work and how they test their software. Second a control task analysis, where the aims decided on after the interviews, is compared to the existing method.
Den ena boplatsvallen är den andra lik? : Miljöarkeologisk intra-site studie av boplatsvallar vid Lillsjön, Anundsjö sn., Ångermanland
Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements, used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.
Förenliga motsatser? : En jämförande studie om aggregering och deliberation i två e-petitionssystem
This essay sets out to compare political participation in two e-petition systems: The Malmö initiative in Malmö, Sweden, and Better Reykjavik in Reykjavik, Iceland. The main question of the essay concerns the aggregative and deliberative qualities of the Malmö initiative and Better Reykjavik, as well as the relationship between aggregation and deliberation. This main question is divided into four subqueries that lead the empirical analysis. These are: (1) Which similarities and differences in terms of design are there between the Malmö initiative and Better Reykjavik? (2) To what extent have these systems mobilized an aggregative political participation? (3) What similarities and differences are there concerning aspects of deliberation? and (4) What is the correlation between aggregation and deliberation like in the two e-petition systems?The method in use is a comparative cross-sectional study with a 'most similar research design'.

Teknologier för fordonsdiagnostik
The capacity to extract information from vehicles has the potential to be very beneficial. Performing analysis on information about fuel usage, emission values and other driving properties of a vehicle can lead to great economic and environmental benefits.This report contains descriptions of two prominent systems for retrieving information of this nature from a vehicle, On-Board Diagnostics and FMS-Standard, and of an implementation of FMS-Standard.The conclusion drawn after this investigation is that these systems do indeed offer access to the benefits mentioned earlier, although to varying degrees and with differing prioritisation..
Vilka kvalitetsfaktorer anses viktigast vid inköp av grönsaker och frukt för återförsäljare i Sverige :
Since Sweden joined the European Union all Swedish fruit and vegetables are classified according to EU Quality standards. One important function is the product description and how it can facilitate the trade; for example in better comparing prices and also to guarantee the quality of the product. This quality standards or product descriptions are written as words of an Act and obligatory for all countries that has joined the EU.
It?s often a demand from the customers to be certificated according to some of many certificating systems. One example is the common worldwide GLOBAL GAP-certification system created by the organisation EUREP which represents the leading European retail traders.
Kartläggning av en arbetsprocess i förändring : Hur distribution över tid, individer och artefakter kan användas för analys vid införandet av Lean Thinking i verksamheten
Lantmäteriets stödenhet Utveckling och IT (UIT) ska inför ett mer agilt arbetssätt. Den agila arbetsmetoden ifråga är Lean Thinking, den västerländska adaptionen av Toyota Production System. För att underlätta vid en övergång till det nya arbetssättet, kartläggs de inledande faserna i projektarbetet, då dessa saknar specifika anvisningar i den nuvarande projektstyrningsmodellen, Praktisk projektstyrning (PPS). Utifrån kartläggningen utfördes så en tvåstegsanalys, den första utifrån ett distribuerat kognitivt perspektiv och sedan utifrån de fem huvudprinciper från Lean Thinking. Resultatet från analysen resulterade sedan i ett antal förändringspunkter som UIT kan använda sig av vid bytet av arbetssätt.
Kvinnodominerade och mansdominerade yrken - En studie utifrån icke traditionella yrkesval
In this thesis I am going to study how women experience working in a male-dominated occupation and how men experience working in a female-dominated occupation. I have chosen a qualitative method, interviewing four women and four men. By using this method I have gained a deeper understanding of what it is like having a non-traditional occupation. In the background I have looked into the unequal distribution of power between the sexes as well as the entrance of women on the labour-market, where the law of equality has had a major impact on the strive towards a more equal distribution according to sex. The theoretical part includes different theories where gender is focused, both when it comes to the biological differences as well as the segregation of sexes that prevails in society and here socialization heavily influences the choice of a vocation.
Småhuset ? val av bergvärme, fjärrvärme eller pellets
This thesis describes the new construction of a small house and it includes studies of three heating systems: geothermal heating, district heating and pellet. The purpose of this thesis is to project a small house which can manage Building Regulations, BBR conditions and then examine three possible heating systems for the small house. This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.
