Prestation vid sönderdelning av GROT med olika typer av maskiner
There is a need for productivities data and data for different types of machines for comminution of logging residues. The lack of data and studies on GROT comminution makes it difficult to evaluate different chains for handling of residue fuels and make system analyses.Four types of machines with three different working principles were compared at six studies during winter conditions. Three to eleven trials during 9.5 to 30.7 minutes were made on each machine. Samples from the produced material at each study were sieved to determine the size distribution of the comminuted material. Samples were also taken from the studies for determination of moisture content.

Varför väljer elever att söka maskinprogrammet?
Abstract The main aim for this research is to come to an understanding for why young people choose to apply for the machine program when the time comes for the students to make their choice of upper secondary school program. The second aim for this research is to try and come to an understanding on how to make the machine program more interesting for future students to apply to. The method of this research is quality method with the usage of interviews. With a total of six students in the first grade going on a school in the middle part of the country I tried to get answers to my questions. There are many things that affect students when they are facing what gymnasium program to choose and a very common answer by students in this study is that friends and work after school are some of the reasons for why students choose, for example, the machine program. The study also shows that parents has less influence of the students choice of gymnasium program and in fact, all students in this study made the choice to pick the machine program as their gymnasium program, but not always the machine program as their first choice. With the comparison of similar studies with my study the results are often in line with what other scientist have come up with.
Perceptuell identifiering av musikgenre
This is a study in the field of Music Information Retrieval (MIR) concerning classification of musicgenre.

Rengöringsmaskin av produktionslina : Rengöring av band i produktion
The project was carried out with SwedSafe AB, engaged in hearing and manufacture of earplugs. Since the company is a world leader in the sale of these products, it is important that they keep a higher level of quality of these products.Production of earplugs is currently a automated manufacturing process that is divided into four conveyor belts and one of the conveyor belts is what will be affected in the project. The belt affected during this process is exposed to various elements such as filling, closing, fermentation and extraction of products. Because the belt gets dirty, degraded products and the work environment is affected. To increase the quality of products and improve the working environment requires an automatic cleaning process, which collects dirt from the belt.The aim of the project is to design a machine that prevents the belt from becoming dirty, preserve molds clean and improve the working environment without disrupting production.

Handledande samtal i förskolan : -kompetensutveckling eller akut problemlösning?
Preschool is a place that is continually undergoing change at a rapid pace and developing the skills of our educators is essential for their ability to keep up with these changes. Guidance conversations can be used as a vital tool for the educators competence development.The purpose of this essay is to investigate how educators, special educators and preschool principals think and reason about the use of guidance conversations in preschool.A qualitative method has been used in the shape of interviews with educators, special educators and preschool principals working within different districts of a medium sized city in the south of Sweden.These interviews revealed that the use of guidance conversations is often controlled by specific needs and is used when a problem arises amongst the children. There are many expectations on the special educators role in these conversations, one of which is the role of conversation leader with the purpose of guiding the conversation amongst involved parties and give them the tools they need to resolve problems by themselves instead of delivering packaged solutions..
Skogsbrukets framtida arbetskraftsförsörjning : skogsmaskinföraryrkets attraktionskraft
The scarcity of qualified forest machine operators as well as the increased competition for competent machine operators among others from the mining industry in Norrland, were the reasons to investigate what attracts and what deters active and potential forest machine operators to the occupation. An interview study was conducted among four groups with four persons in each group. The groups were students in year 1 and 3 respectively at a forestry school at upper secondary school level as well as employees of a forest company and employees of contractors. The majority of all respondents were of the opinion that their interests in machines had been important for the choice of occupation. But for the active machine operators both the interest in the forest and their interest for machines have had importance for choosing this occupation.
