Byte av kontaktdonsgränssnitt för Scania bromssystem

This master thesis was carried out at Scania in Södertälje, Sweden. It investigates the possibility of changing a connector interface that is used when there is a need for splicing the wheel speed sensor and thereby determine the consequences.The problems that exist with the current connector interface occur during assembly, as more time is required to complete a connection in a reliable manner. A complete connection requires joining the male and female connector, insert the connection into a protective retainer and then strap a cable tie on each end of the retainer. This process makes it more time consuming and it requires 20-30 seconds to complete the connection. Solving this problem would save time and enable easier assembly, therefore resulting in economical benefits.This thesis was accomplished through discussions with different sections at Scania, studying available documentations, observations during assembly, writing a requirement specification and contacting suppliers.The aforementioned methods resulted in four connector suggestions, the DT and DTMH connector from Deutsch, MCON connector from TE connectivity and MLK connector from Kostal, each of them compliant with the set demands of the surrounding environment.

Barnsjuksköterskors erfarenheter i möten med små underviktiga barn och deras föräldrar

The aim of child health care is to promote health and development for all children, to early identify problems that concern children´s growth and development and to prevent ill-health among children. Today in our society the proportion of children who are underweight are few.The aim with this study was to describe paediatric nurses experience in meeting with underweight children and their parents. Interviews were implemented and analyzed according to qualitative content analysis. Focus was placed on looking at differences and interpretations in the text content. The analyse resulted in six main categories, such as a need of sensitivity and a holistic view from the nurse, difficulties in handling the meeting because lack of tools.

Rening av avloppsvatten med anaerob membranbioreaktor och omvänd osmos

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

Dags för IT-boom i hotellbranschen?: Om hur svenska förstaklasshotell med hjälp av IT kan förbättra service för sina gäster

This thesis seeks to investigate how Swedish first class hotels by use of IT can improve customer service and thereby increase the share of loyal guests. The authors have conducted a qualitative study predominantly consisting of an interview-based case study at one of Stockholm?s largest independent hotels. To get a broader and more generalized picture of the hotel industry four smaller studies at other hotels in Stockholm were also conducted. The findings suggest that the use of IT can improve the communication between the hotel and its guests and make possible a continuing relationship between visits that strengthens guest commitment.

Design av PID-regulator baserad på kommersiell processormodul

The idea to develop  a platform for a PID-controller came from the need to control the temperature in  an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.

Wild boar paradise : What makes the Swedish wild boar reproduce more or less successfully?

Due to the growing wild boar (Sus scrofa L.) population in Sweden there has been an increase in wild boar related traffic accidents, damage on cropland, and conflicts regarding the management of the wild boar. Knowing what makes the wild boar reproduce and survive more or less successfully in different geographic areas is an important part of managing the population. According to previous studies the wild boars rate of increase varies from county to county. The aim of this study was to test, on the county scale level, if landscape composition and diversity as well as people and hunter densities might be the reason for this variation. The first hypothesis was that a big proportion of forests and cropland would increase the rate of increase.

Registrering av konstbilder: En översikt av forskning och praktik i en domänspecifik form av kunskapsorganisation

The purpose of this thesis is to present a review of research themes and practice in the field of art image registration. The objectives of the review are twofold. The primary task is to distinguish which problems, in regard to theory and practice, that have been dealt with in the field of art image registration and the secondary task is to investigate which discursive, institutional and tool-related factors have had an impact on theoretical discussions and practice in the art image domain. The empirical content in the review is structured according to four epistemological viewpoints and is analyzed with a domain analytical approach. The result of the study is that two major problems are frequently discussed in the art image domain, namely lack of standardization and which discourse is the best suited for registration of art images.

How the regulation could work is also discussed in the section with the results from the interviews. The discussions were produced by people whose background in one case or another can relate to the phenomena web bots. In that way this study was limited to few, but more profound interviews which would enable analyses of web bots existence.

Med fokus på möjligheterna istället för sjukdomen : en kvalitativ undersökning om validations- och reminiscensmetoden utifrån ett personalperspektiv

The purpose of our study has been to examine the methods of validation and reminiscences from an employee point of view. To answer our aim a qualitative disquisition with four assistant nurses and one pedagogue in craft was conducted. The result was divided into three different themes: the view on people with dementia, merits and demerits with the methods and to work with people with dementia. The analysis of the result was made from selected parts of the system theory and symbolic interaction theory.The result of our disquisition can be summarized in that all our interviewed persons above all only can see advantages with the methods and several express that they are good tools to use in their work with people with dementia. The majority of our interviewed persons make use of the methods in everyday, spontaneous, meetings with the elderly.

Är ökad pressfrihet dåliga nyheter för korruption? - En kvantitativ dataanalys som testar styrkan i sambandet mellan pressfrihet och korruption.

This paper aims to broaden the discussion on how press freedom can be a powerful tool in the war on corruption. Previous studies have shown a significant relationship between more press freedom and less corruption, it also shows that the causal link runs from press freedom to corruption and not the other way around. There are quite a few studies on the impact of a free press on corruption and therefore there is a lot more to be published on this issue.This paper looks at press freedom as one of the most important parts of a democratic society and that it plays a vital role in reducing corruption as both an informant on key issues and also as a ?watchdog? on society. But press freedom cannot be seen as an ?easy fix? in a country or the international community's struggle to reduce corruption.

Visualisering av svarstider mellan mobila klienter och datacenter

Rapporten är en sammanställning av gruppens samlade erfarenheter och lärdomar av ett projekt vars syfte var att utveckla ett verktyg som ska visualisera svarstider mellan mobila klienter och datacenter. Genom att använda kontinuerlig prototypning har gruppen kunnat arbeta på ett användarna sätt för att uppfylla kundens verkliga behov. För att uppnå detta användes utvecklingsmetodiken Kanban. Under projektets gång anpassades metodiken för att bättra passa in i arbetet.Projektets användartester har lett till sammanfattande erfarenheter om visualisering av data. Visualiseringar som projektgruppen ansetts tydliga uppfattades inte alltid på samma sätt av användarna.

Informationskällor under internationalisering : Svenska små företags tillvägagångssätt för att tillägna sig kunskap och information

There is an ongoing process where the free market within the European Union is expanding, partly through the incorporation of new member states, partly through the signing of association agreements with nearby countries and regions. When trade barriers are removed in different ways more companies consider an internationalization of the company. However, the procedure of the internationalization of companies is a rather new and unexplored area in the context of research. The focus of this study is therefore to examine how a few companies situated in Sweden, has proceeded while searching for knowledge during the internationalization process. Data has been collected through interviews that have been balanced with information from Internet and other sources.
