Effektmätning i pump
The interest for power and energy measurement has greatly raised with todays increasing electricity prices and enviromental awareness. In the search for energy efficient solutions, the measurements are more complex due to increasing of non linear components. Harmonics and non sinusoidal voltages put high demands on sampling and filtering. Meanwhile, the price must be controlled so the customer still will find it interesting to invest in smaller plants. ITT W&WW asks for a robust, heat resistant power meter with compact dimensions to allow mounting inside the casing of a pump.
Farmers´ decisions factors : a case study
This study examined the factors influencing dairy farmers´ decisions to invest in automated milking systems (AMS). The problem studied involves uncertainty, information and complexity for dairy farmers in specific decision contexts. The frame of reference in the thesis combines contingency theory and decision theory and is used in a qualitative analysis of a set interview with dairy farmers who have recently bought an AMS and salespersons from Delaval, one of the AMS suppliers.The aim of this study is to develop an understanding of the decision making processes of dairy farmers, and in particular to identify which types of factors influence the outcome of an investment decision in the technological development of a farm.The study uses Thompsons` (1967) theory about the structure that organizations develop to handle the input of information. Thus, interest is focused on how a farm business structure handles information in the AMS decision, investigating the differences in information with Delaval?s "feed first principle" system and Lely?s "free cow traffic" system.The results of the qualitative interviews with the dairy farmers who bought an AMS show that there are three important factors that influence the outcome: employees, suppliers and the owner.
Påverkan av ackulturation på invandrares upplevelse av arbetets mening: en fenomenologisk studie
The purpose of this phenomenological study was to facilitate increased understanding of immigrant's experience of the meaning of work with focus on how that meaning can change as a part of the acculturation process. Participants (n=13) from eight countries answered an open question. The responses were analysed using Meaning Construction Analysis (MCA)-Minerva and the individual's life-worlds were made visible and discussed. The themes meaning of work, work, unemployment, education, adjustment, immigration, Sweden/country of origin, dreams, possibilities and self appeared as jointly shared important aspects. The results indicate that work is of central importance, and although the individuals share certain experiences, the meaning associated with the themes is of a complex and individual nature..
Integration på arbetsmarknaden : Ett sysselsättningsprojekt om arbetsmarknadsproblematik för invandrare
Integration of the labor is becoming increasingly topical, with increasing immigration. Labour market integration has been proved to be problematic, partly due to linguistic and cultural differences between the migrant's home country and Sweden. Difficulties with labour market integration have resulted in high numbers of unemployment and dependence on social welfare. Projects VIAM is an employment project conducted by Folkhälsobyrån AB in Västerås, aimed at finding jobs for welfare dependency immigrants. The purpose of this study is to investigate how the informants on Folkhälsobyrån and administrators on the Social service in Västerås has experienced the work of the project VIAM, development issues and the informant´s and administrator´s perception of factors that are influencing immigrant´s employment situation in Västerås.
Ungas avhopp från kommunfullmäktige : En studie om unga fullmäktigeledamöters beslut att lämna sina uppdrag
Young councillors are currently under-represented in Sweden's municipalities. Young councillors are also stepping down in greater numbers than older members. This paper explores the reasons why young councillors choose to resign from their mission, so to identify possible remedies to the problematic trend of underrepresentation of younger people in local authorities in Sweden.This qualitative essay intends, through interviewing politically-active young people who has left their assignment, to study the reasons for resignations from elected posts. To see what could be the reason I have looked at previous studies and theories about opting out but also tried to remain open to identifying new and emerging trends previously undetected in existing surveys.The results showed that the political assignment proved to be too time-consuming, with young people choosing to spend their time on career and leisure. Those who resign from political life often express criticism towards the Municipal Council; they consider it tedious and many complain of having little influence.
Ger en kvinnlig CFO högre redovisningskvalitet?
The executives of a firm possess considerable influence over a company's financial reports. The numbers can be adjusted in a favorable direction by engaging in Earnings Management, which harms the reliability of the financial reporting. Previous research suggests that Earnings Management can differ between genders. In recent years the debate about a woman's role in the business world has received generous attention in media. Moreover, the presence of women in leading positions has become a relevant issue for firms.
RAFFLES CITY - Lokala och globala dimensioner av ett urbant komplex i Chengdu
In a time where many Asian metropolises experience an expansive development new urbanconditions are created and the already existing disappears or being replaced. Asian cities develop ata pace that is unprecedented in our history and which, through a western perspective can seemharsh. By focusing on an urban complex in Chengdu, capital of the southwestern province ofSichuan China, the study asks; is it possible to see this rapid urbanization from another perspective?The study examines the local and global dimensions of Raffels City, and how concepts such asnostalgia and authenticity, related to the city, can be understood in an urbanization that is so markedby massive demolitions. The study shows that these concepts can be expressed in several ways, andthat an awareness of them does not necessarily control the view of the city..
Duo - ny skola på Hälsingehöjden
A variety of demands have to be considered in the design of a new opera house in Galärvarvet. All possible viewpoints are important to be aware of, as is the need for the new building to be a contrast to the already existing opera house in Stockholm. The restricted site also makes a multitude of demands on the building's design.By rationalizing the layout and structure and also by making the footprint smaller, the complex building of over 30 000 square meters can be fitted and blended into the existing physical context. Unlike the existing opera house in Stockholm, the new opera house shows the rationality and the advanced technology that lies behind the scenes and becomes the character of the entire building. Through the dynamic façade, the new opera can convey any character it so desires, just like scenes do through different settings.
En studie av viltets påverkan på Skogssällskapets fastighet i Selesjö
This degree project investigates how elk, roe deer, red deer and fallow deer can affect an estate in Östergötland. The inventories performed within this project, were completed on an estate in Selesjö, northern Östergötland. This property is used to demonstrate wildlife management.
The methods used in this study were originally developed for areas larger than individual properties. Three inventories were completed in the study. These included the recording of the number of droppings and the amount of eaten pasturage, as well as the level of damage on young trees.
Analysis of CD4+ and CD8+ T-lymphocytes : A comparison between EPICS XL and Celldyn Sapphire
Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.

The female chiefs have grown in numbers, and because of that people have started to focus on whether there are any similarities or differences between the female and male leadership behaviors. The essay is about similarities and differences between female and male middle chief?s idea about effective leadership behavior.Our analysis is based on a qualitative study, where we have made four interviews with four chiefs in industrial companies.
Flyttprocessens påverkan på identiteten ? utveckling eller avveckling? : En fallstudie kring flytten av Hjalmar Lundbohmsgården i Kiruna
The purpose of the thesis is to investigate and analyze how three different actors linked to the urban transformation in the city of Kiruna, in this case LKAB, the Municipality of Kiruna and the County Administrative Board of Norrbotten, believe that the identity of a historical monument that is marked cultural heritage is affected by future relocation. The second part of the study is to investigate the impact the building might have on the city in the future. This study is based on the relocation of Hjalmar Lundbohmsgården.The study is based on a qualitative approach in which five informants from the three actors were interviewed. The interviews have been analyzed through thematic analysis, where a combination of theoretical thematic analysis and empirical thematic analysis was used. The result shows that the new location of Hjalmar Lundbohmsgården is preferred to be in a suitable context close to other cultural buildings. All informants agree that accessibility is a fundamental element in, which a synergistic effect is an increase in visitor numbers.
Posthuset blir hotell En studie av Centralposthuset i Göteborg och dess omvandling
This essay in Art History treats the former Central Post Office in Gothenburg, Sweden, and its recent transformation into a luxury hotel. The magnificent original building in neo-classical style, inaugurated in 1925, has been supplemented by a twelve stories high tower in postmodern style containing hotel rooms and suites, creating a complex architecture. The approach of this essay is that of ?lived architecture?, that is, how people experience and act in relation to the building. It is argued that the history of the building is rewritten in the marketing of the hotel and the management?s concept of creating a comfortable ?mini-world?for its guests.
Etablering av höstvete med reducerad jordbearbetning :
The payment for produced grain is constantly going down in price. It is important for farmers to become more effective in cultivating more land in a shorter time perspective. At the same time we have to calculate with the risk of getting lowered subsidies from the EU. This is why I would like to find out the possibilities for establishing winter wheat without ploughing.
I hope to find a difference in the number of plants due to different soil preparations. With this experiment I expect to find out whether I can establish winter wheat at a lower cost, with the same numbers of plants per square meter.
Quadrotor UAV : Konstruktion och användbarhetsstudie av en UAV i sensornätverk
Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.
