Experimentell konstruktion av pickupsystem anpassat för trummor med hjälp av MATLAB
For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.
Service Level Management : Equalize unloadingencrustation at Stora Enso ? Skoghalls bruk
The report is part of the university´engineer program within Industrial Organization and Economics with specialization in Logistics and Managment at Jönköping´s university.Skoghall´s mill underlies a large supply chain, which means there should be a lot of areas in need of small improvement measures. This report illustrates a small part of one of these areas and is focused on the loading distribution services in the terminal Vänern.At the moment there´s a very unequal load of the load carriers SECU box and Container at the terminal. Skoghall´s mill has the desire to equalize the high and low load levels of the 2 loading carriers named previously. One of the options to solve the problem is to set a limit of how much the carriers can load per week or per day. The mill also wants it to be investigated if the proposition would influence the customers in any way and if both the company and its customers could handle a lower level of delivery services in case the proposition was to be applied.The goal to be achieved with this thesis is to provide balance to the unequall loading of the 2 load carriers, SECU and Container, and investigate whether or not the Skoghall´s mill´s customers, could manage the lower degree of delivery service that the proposition would imply.For this goal to be achieved, random sample investigations were taken from orders of a customer that is provided with SECU load carriers and the same was made with a Container´s customer.
Interpersonell problematik och arbetsallians i psykoterapi : Klientens upplevelse och förändring av interpersonell problematik och dess relation till arbetsallians i psykoterapi
The purpose of this study was to examine interpersonal problems and its relationship to the working alliance in psychotherapy. To examine this, data was used from Umeå and Lund University psychology practice client database, which clients responded to by using the self-assessment scales Inventory of Interpersonal Problems Circumplex Scales and the Working Alliance Inventory. The sample consisted of 201 participants that answered the questionnaires both before and after psychotherapy. A second sample consisted of 93 clients who specifically sought help for interpersonal problems. Results showed that the level of interpersonal problems before and after psychotherapy changes.
Evaluation of lithium-heparintube analyses performance
Today, some kind of laboratory results is required for around 70% of the diagnostics and follow-ups for diseases. In many of the cases the time from sampling to a result is very critical. Therefore the discussion of how to improve this situation has begun. For many analyses serum has been the routine choice for a long time but now it is disputed. After blood collection in a serum tube it is essential to wait 30-60 minutes before centrifugation and analysis of the sample, a long time for someone in an acute state.
Inkomstfördelning och ekonomisk utveckling -en studie av forna sovjetstater
The economic development and industrialization that has taken place in many parts of the world during the past century has brought about a huge increase in economic welfare. During this process, it has repeatedly been debated whether the gains from economic development are shared by everyone or just a few. In the field of economics, vast research has been conducted on this particular subject ever since the 1950?s. The most famous contribution might be said to be Simon Kuznets article, Growth and Income Inequality from 1955 and the ?inverted U?-hypothesis that was formulated on the basis of that article.

Skogs- och energibolagens attityd till förnybara drivmedel vid upphandling av transporttjänster i norra Sverige
Sweden's government is dedicated to the goal of having a vehicle fleet that is independent of fossil fuels by 2030. Achieving these goals requires, among other things, new types of fuel that give lower net emissions of carbon dioxide. The present market includes stations offering lowlevel blends of renewable fuels in conventional diesel as well as some stations offering renewable fuels only.
The purpose of this study is to survey purchasers? attitudes to the use renewable fuels in roundwood and bioenergy transport in forest- and energy companies.
The study was based on qualitative interviews through a combination of face-to-face meetings and telephone interviews with each sample group. The total number of respondents was ten (10), consisting of five (5) from forest companies and five (5) from energy companies.
Transport service purchasers were generally positive to renewable fuels and considered these necessary in the future.
Barn i familjehem: En studie, om långtidsplacerade barns fysiska och psykiska hälsa, tonårsgraviditet, skolgång samt om föäldrarnas psykiska hälsa och mortalitet, i en undersökningskommun
The main purpose of the study was to analyse the well being of children placed in foster care for at least two years, in one sample municipality. An assessment was made of how the social service admistrated and took responsibility for these children in terms of schooling, physical and mental health. To further understand the situation of the children three areas of investigation were added concerning; teenage pregnancy, the mental health and mortality of the biological parents. To receive answers to those questions a qualitative interview method was used, with structured questions to social workers working with foster care. The author also studied journal notes and child investigations to receive a more comprehensive picture.
Bryggor - En studie av bryggors förekomst i publika bolag och påverkan på träffsäkerhet i analytikerestimat av EPS
Previous studies have shown that there is a relationship between voluntary disclosure and analysts' forecast accuracy. However, there has been no research conducted specifically on bridges. Bridges contain information on how components such as price, volume, foreign exchange rates and acquisitions have impacted the financial performance between two periods. The main purpose of this thesis is to investigate the usage of bridges in quarterly financial information of companies listed on Nasdaq Stockholm. We provide a descriptive mapping of bridges and find that 30 out of 268 companies are presenting bridges as a part of their voluntary disclosures, with large firms being the most frequent users.
Att kommersialisera och sa?lja en plats : en analys av resereklam, representationer och geografiska fo?resta?llningar
Pictures are often used when marketing a tourist destination. Photographs of a place, a destination, are used to convince customers and stimulate daydreaming in order to turn a potential customer into a real customer. For some people the photographic representations of a place is the only one they experience. With this in mind, it is reasonable to question how representations of places and geographical imaginations are being (re)produced when marketing a destination by using photographs. This paper aims to study how representations of place and people are used when marketing a tourist destination via travel commercial.

Tro, Hopp och Tveksamhet : En studie om profil, image och kommunikation för Svenska kyrkan Västerås
What does the Swedish church Västerås stand for today according to the employees and how do they want to profile themselves to the target group? What image and what expectations does the target group have of the Swedish church Västerås? How can the Swedish church Västerås communicate uniform, with the intent to create mutual value with the target group?The purpose of the study is to make recommendations to the Swedish church Västerås for their prospective communication plan by examining their profile and target group's image and expectations of the organization. The study also aims to examine how the Swedish church Västerås can communicate their brand uniform.The study applies a qualitative research with deductive approach. Data were collected through semi-structured interviews with a sample of the employees and focus groups with a sample of the target group.Better match between profile and image means that SkVs employees better understand the organization and can communicate more uniform which leads to a stronger brand identity. If SkV understands what is relevant for their target group, they can reduce the total cost of customer delivered value and thus increase the total value.
