Omkonstruktion av treaxlig plockrobot och dess plockverktyg
This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.
Äldres individuella behov borde ligga till grund : En studie om dagstidningars framställning av äldre med omsorgsbehov
This bachelor´s thesis wants to look closer at librarians´ experiences of comics, manga and graphic novels. In order to bring these experiences forward qualitative interviews and the method of phenomenography was used. The material was then examend againstna theory of previous research, revealing that the problems librarians in Sweden face with these media are largely the same as the problems faced by librarians in other parts of the world. It also became clear that the participating librarians held a positive attitude to the presence of comics, manga and graphic novles in their libraries..
Psykisk ohälsa bland barn och ungdomar i socialtjänstens öppenvård. : En kvantitativ studie om psykisk ohälsa, kön och socioekonomi i Södermalm och Rinkeby-Kista utförd med ?the Strengths and Difficulties Questionnaire?(SDQ)
The aim of this quantitative study is to describe the prevalence of mental health problems within the group of children and adolescents who receive support from two in home care units within the social services of Rinkeby-Kista and Södermalm stadsdelsförvaltning in Stockholm. Another purpose is to examine whether socioeconomic background and/or gender are associated with the prevalence of poor mental health, or mental health problems of a specific kind, in the studied population. Mental health is measured with the SDQ, a behavioral screening questionnaire that is widely used in Sweden and internationally. The study is based on data collected by the two units, which routinely screen children and adolescents with the SDQ. The main results of this study indicate that mental health problems are common in the studied population.
Statusbedömning och förbättringsförslag för startkedjemaskineri, startkedja och linspel för stränggjutningsmaskin
The main goal with the master thesis has been to do a status evaluation of the chain machinery with its start chain and wire to secure the production on a short basis due to that a reconstruction is not planned at this time. An evaluation of the condition of the start chain and the rollers in the chain depository has been done. An offer has been requested for a new start chain and the evaluation of the start chains may be a basis for the decision taking. The production has been able to go on, although it has arisen some problems which have been difficult to find the causes for. There is no gathered ?picture? of the machinery status and a mapping of each machinery has been compiled of comprehensive logs.

"Jag tycker det är en snäll typ av marknadsföring" : - En kritisk diskursanalys om content marketing i podcasts.
The aim of this study was to investigate in what way content marketing can be understood through podcasts as an alternative marketing tool. The material which the study was based on is Ölpodden, a podcast initiated by Carlsberg Sweden. The study intended to shed light on the interdiscursivity that emerges when brands are communicated through podcasts. Another aim was to understand how relationships and identities are constructed through the podcast by examining its intended audience. In order to achieve this a critical discourse analysis was used as both underlining theory and comprehensive method.
Hur påverkar förtätningen stadens grönstruktur? :
Urban density is not new, but rather one side of the continous processes of change underway in the city. During the urbanizing boom of the industrialization, when the cities grew bigger, the first spaces to be built on were vacant and planted areas in the interior of the district. The gardens that once were there were replaced by yardhouses. The idea of urban density is that a dense city means less distance between residential areas and workplaces, resulting in fewer shipments and travelers, which ultimately leads to lower energy consumption and lower emissions. Urban density may lead to shorter
distances, but not necessarily.
In the wake of urban density the greenstructures of the city is shattered.
The possibilities for green areas to contribute to the health of the city and its inhabitants is dramatically reduced.
Våga tro? ? en studie om förortsungdomars tankar kring framtida karriärval
Nowadays in our society we find it hard for some groups of people to integrate in society. It?s known by media, that the suburbs are presented by a negative view, which often highlights the social problems in these suburbs. We can see that the suburbs still get associated with social problems such as segregation, different attitudes and behaviors, cultural conflicts, poorness etc. This kind of presentation of the suburbs affects not only the society but also the individual living and the personal perception of the individual.
Monitoring and pest control of Fruit flies in Thailand : new knowledge for integrated pest management
Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.
Läsande lyssnare ? lyssnande läsare. En kvalitativ studie av ljudboksanvändare
The purpose of this thesis is to investigate peoples experience when listening at audio books. During recent years the use of audio books has increased significantly. With that knowledge and the fact that this is an almost unexplored area within Library- and Information science our interest grew even stronger. The thesis is based on two different theories. To be able to place audio books in a context we have applied a media- consumption perspective by asking questions like when, where and how the media-consumption takes place.

Miljöpåverkansbedömning vid tillverkning av etanol från cellulosabaserade råvaror : ekologisk gård självförsörjande med drivmedel
Fuel produced from renewable resources is of big interest. In this project the difference between a few different renewable materials are compared on the matter of environmental load when ethanol is produced. The renewable materials that are compared are Salix, straw and reed canary-grass (rörflen). The cellulose in the material is cut down to small pieces and then hydrolysed so that the sugar from the cellulose can be fermented into ethanol.
Tha amount of ethanols that is studied in this work is the smount of ethanol needed to cultivate 1000 ha. The functional unit in the report is 1000 ha.
Zilent Ocean : EL-KONVERTERING AV INOMBORDSMOTORER TILL SEGELBÅTAR

Zilent Ocean is an extensive project within Development engineering program at Halmstad University.
Carnegie: En studie av tillämpningen av "verkliga värden"
A recent development in the field of accounting has been an increasing use of fair values in financial reporting. In 2005, this development was reinforced in Sweden by the adoption of the International Financial Reporting Standards. The aim of this thesis is to discuss the problems related to the use of fair values, through a case study of the Swedish investment bank Carnegie. In May 2007, Carnegie announced that the result had been overly stated by 630 MSEK, due to the valuation of derivatives within the trading department. The empirical material consists of documents produced in the legal process between Carnegie and the Swedish Financial Supervisory Authority.
