This is a study in the field of Music Information Retrieval (MIR) concerning classification of musicgenre. The study uses a music listening experiment and Machine learning methods to determinewhether or not the drum sounds from different songs contain sufficient information to classifygenre.MIR methods are used to extract data from the audio signals. The data is used together with theclassification results of the listening experiment to train different Machine learning algorithms toclassify the songs in different genres.The results indicate that using only drum sounds for genre classifications works well, both forlisteners and for Machine learning methods..

The company have design an machine that exist in six example that runs in the production. To be able to use the machine the company have to work out a CE-marking. The process that summed up all the document that needs for the machine to make a CE-marking. The documentation includes a total drawing over the machine and a risk analysis performed by a group employers on the company.

Deposits can be formed in the paper machine due to sticky materials from wood and recycled paper. These deposits get stuck on process equipment and cause the product quality to deteriorate and the efficiency of the paper machine is reduced. The purpose of this thesis is to increase the understanding about deposits among machine operators, and to suggest methods that can be used to reduce the amount of deposits formed in Bravikens paper machines.To fulfill the purpose of the thesis a pre-study, a literature review and interviews with machine operators and production staff, were carried out. These methods led to the planning and creation of an education about deposits for machine operators.The education about deposits for machine operators consisted of an interactive lecture to introduce the subject of deposits and a subsequent discussion. This approach was chosen to give the machine operators the opportunity to discuss their work situation on the paper machines related to their new knowledge about deposits.

Resignations are common in all business sectors and can also be found among forest machine operators in the forest business. As the industry today faces a lack of forest machine operators it is justified to determine why machine operators choose to quit their jobs. The aim of this study was to a) find out the number of machine operators that have resigned b) identify and analyse the cause for these resignations c) identify the reasons why the machine operators started to work in the forest and d) give suggestions on different measures that will limit resignations amongst forest machine operators. A questionnaire was sent to machine operators who have quit working as employees, contractors or as employees for contractors with Holmen Skog during 2003-2007. 32 machine operators responded to the questionnaire. Interviews were made with 10 machine operators who had answered the questionnaire to gather more qualitative data. The results of the study indicate that fewer forest machine operators change profession than employees in other occupations in Sweden.

Our greatest interest within crop farming is to grow sugarbeets, that?s why we want to write about something new in this sector. We heard that a new concept had come to Sweden so we wanted to find out everything about this machine. This new technique was a self-propelled cleaning loader for sugarbeets. This machine is supposed to replace a loader and a cleaning machine when the sugarbeets is going to be loaded, cleaned and delivered to the sugerbeet factory. The cleaning loader picks up the sugarbeets with rollers from the pile, which is placed close to the road.

AbstractWe have been honored to work with a company called Frimeko AB. Frimeko is located in Halmstad where they make and sell furniture for school and office environment. Our task is to construct a new, more modern sewing machine table for schools. The task is to use the same function as before, ease the storage and production of sewing machine.Efforts to develop the new sewing machine table resulted in that we came up with an innovative design that the company is pleased with.During this project the group has used the method from ?Fredy Olsson Konstruktion? .

When harvesting ley you hope to get a fast drying and a faster harvest. If there is a system with round bales, you need to have a dry matter close to 45 %. To make this as fast as possible, there is made a machine which pick up the grass with an pick-up. It turn the grass over and put it behind the machine (figure 2 and 4). There are few tests to prove the efficiency of this machine.

This study has been performed with the help of forest machine operators in order to improve the forestry planning at Holmen Skog Örnsköldsvik-region. For Holmen Skog forestry planning is basic for a successful forestry. In a survey I have investigated what can be improved in some areas that are planned for harvesting. The result of the investigation will be used to support the machine operators as much as possible. The study has generated 49.5 % of responses and because of this low response rate, no clear conclusions to anyone else except the responding machine operators can be drawn. It has been proved that there are some details in the forestry planning system that are inadequate, such as marked routs for trails, tractor paths and buffer zones against streams. The quality of forestry planning varies greatly between different locations, as much as 50 % of the responding machine operators thought so. Over 40 % of the responding machine operators claim that the information from Holmen is insufficient. One thing that would improve the forestry planning within Holmen would be to educate all forestry planners and then do continuous follow-ups..

Facial expressions are a part of our body language that helps us to clarify the verbal communication between humans. We use our facial expressions every day, both consciously and unconsciously, to express emotions and attitudes depending on the situation. The hypothesis of the study is: Given a facial expression, how well can Microsoft Kinect, as an input method, determine a person?s feelings with the two algorithms Naive Bayes and Sequential Minimal Optimization? The feelings are limited to happy, sad, surprised and disgusted. With the help of Kinect, a person?s facial data, both coordinates of the face and parameterized data, were saved and used for Machine learning.

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.

This thesis presents the results of the implementation and evaluation of two Machine learning algorithms [Baz98, GB97]based on notions from Rough Set theory [Paw82]. Both algorithms were implemented and tested using the Weka [WF00]software framework. The main purpose for doing this was to investigate whether the experimental results obtained in [Baz98]could be reproduced, by implementing both algorithms in a framework that provided common functionalities needed by both. As a result of this thesis, a Rough Set framework accompanying the Weka system was designed and implemented, as well as three methods for discretization and three classi cation methods. The results of the evaluation did not match those obtained by the original authors.

The comprehensive goal in this study was to examine important factors in an introduction of a new machine team. The aim was to identify what elements should be part of an introduction program for new machine team. The examination was done together with Stora Enso Skog. A new machine team and their supervisors where analyzed during a six month period. The evaluation was done with open interviews of the team members and their supervisors. The main question was what should be included in an introduction program to develop a successful machine team as effective as possible? Interviews of the new team and analyses gave good indications how the procedure should be done.

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.
