En studie av metodbyte vid sintring av hårdmetaller till mikrovågsintring samt dess ekonomiska fördelar : Självständigt arbete i teknisk fysik med materialvetenskap & Självständigt arbete i kemiteknik

The aim with this study was to investigate the effects a change of manufacturing process would have on the mechanical properties of drill bits made of a WC/Co composite used for stone cutting. The method used today is sintering, where the material is heated in a conventional sintering oven. The other method was microwave sintering, where the material is heated by radiation in the microwave region. Also an investigation of the manufacturing cost were made.The main difference between the two heating methods is that the conventional way is a rather slow process and the microwave method is very fast. The material is also heated homogeniously in the method with mirowaves, aposed to the case with the conventional sintering where the material is heated from the outside in.This makes the material harder and more wear resistent.

Med siktet inställt på bragd, hinder och hopp : En granskning av handikappidrottens plats i det mediala rummet

Purpose/Aim: The aim of this study is to (1) analyze the amount of exposure disability sports get in Swedens biggest newspaper (Aftonbladet), (2) look at how Aftonbladet portraits disability sports and it?s athletes, and finally (3)  to see if there has occurred any change over time (during the last eight years). Material/Method: The first method used is a quantitative analysis to measure exposure.The second method is a quantitative content analysis which is used to analyze how disability sports are portrait.The third method is rhetorical and is also used to analyze how disability sports are portrayed. Main results: The study has shown that disability sports get very little exposure in Aftonbladet. The articles in the newspaper that cover disability sports are portrayed from a personal point of view without much focus on the athletes achievements regarding his or her sport.

Korta musikresor (KMR) : Mot en teori om KMR som en musikterapeutisk metod

This study was conducted in the Master program at The Music Pedagogical Center (MPC) at The Royal College of Music in Stockholm. Korta musikresor (Short Music Journeys) is the Swedish term used for a receptive method of music therapy adapted from the tradition of The Bonny Method of Guided Imagery and Music (BMGIM) and the theory and practice of Expressive Arts Therapy. The KMR method uses carefully selected short pieces of music, lasting between 2 and 5 minutes, to work on various psychological problems and life- crises. The music session is conducted in a slightly altered state of consciousness with a clear focus being established beforehand in a verbal dialogue with the psychotherapist. There is also the possibility of using artwork to process and explore the imagery after the music listening.

Vädrets påverkan på byggarbetsplatsen

This exam report contains studies about how the weather affects the construction site from a planning and productivity perspective. In 1960?s the contractors started to build during the winter, since then the demands to obtain a good construction has been higher on both the contractor and then promoter.In this report you will see how the different actors at the construction site handle the weather problems. By several interviews of the actors at the construction site there have been opinions about the weather situation which has been collected. To get a wide perspective of the problem, field studies from four different construction sites been made.Weather statistics over Halmstad is a mayor part of this report.

En jämförelse avseende beståndsgående-och stickvägsgående gallringsmaskiner

The purpose of this report is to investigate and compare the difference between stand-thinning machines and strip-road thinning machines, and how they affect the stand on behalf of future growth, theoretical economic result, wind impact, snow pressure and density of stand. The investigation is regarding the first commercial thinning of pine stands, after pre-commercial thinning that was well conducted. The investigation area was located near Katrineholm, Sweden. The measurements that were measured were strength of thinning and amounts of wind throws, snow-breaks and hauling damages. The results that emerged, was that thinning with strip-road machines had a significantly higher strength of thinning over all, as compared with the stand- thinning machines (45 percent versus 30 percent). Comparisons between wind-throws, snow-breaks and hauling damages of the stand could not establish any significant differences between the two methods that were investigated. Conclusions, over all, were that if forest owners want to have more timber volume left for second thinning and final cut of the stand, the forest owners should choose the method with stand-thinning machines. From the point of view of gentle treatment of the stand and ground damages the choice should be the same. However, the method with strip-road thinning machines is the most common and accessible method in Sweden. Most likely it is the most economical way to manage the stand for forest owners in present time. If the method with stand-thinning machines is becoming more common in Sweden, it is suggested for forest owners to consider the stand-thinning method as a candidate for treatment due to economic aspects..

Datormodellering av en värmelagrande betongväggs inverkan på det termiska klimatet i ett växthus

This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.

Dekoration av plasttallrikar

A group of two people, Jelena Durkan and Johan von Heideken, have worked together on an assignment from the company August Lundh AB. The company manufactures plastic products for all sizes of catering establishments. The basis for this thesis is a pre-study which shows that many of the users would be more drawn to the plates that the company manufactures, if there was a motif on the plates.This thesis will present the method of application for the motif that best benefits the company, with regard to the requirements placed on the motif, application method and the costs. The group found five relevant methods that were more carefully examined and compared to each other. Those are:Laser engraving, Hot-stamping, Injection molding, In-mould labeling and Pad-printing.The tools that have been used to solve this problem are: Requirement specification, QFD and OEE.

Spam : den nya tidens onlinegissel

This thesis takes on a broader perspective of the modern age phenomenon we call spam. One of the aims of this thesis is to present and to compare the variety of methods used in the day-to-day fight against spam, as far they have evolved today, but also to present and discuss some alternative methods for suggested future use. The properties of a common e-mail spam are analyzed to show how the components that make up the structure in an e-mail can be used to classify spam. Furthermore I explain the naïve Bayesian classification methods, the signature-based method, the commonly used rule-based method and the challenge and response method and discuss these. The widespread use of blacklists is also explained and a close new variant to blacklisting, Turntide is presented and discussed.

Byte av systemutvecklingsmetod : En verksamhetsnytta eller en nödvändighet?

 AbstractSystem methodology is in the very heart of system development, it is a crucial part of how you define your work, how you choose to approach the actual problem at hand and how to solve it. Researchers in the system development field has shown that not all methods in theory are in compliance with how it is practiced by the companies who use them. In our thesis we have studied a larger international IT- company and one of their local offices in Sweden, who some years back changed their system development method from a more traditional to an agile one. Our aim of this study has been to establish whether both of these methods has differed between theory and in actual use, and if so, why this has occurred and what the underlying rationality might have been to promote this change. Our questions that we sought to answer were; 1.

MÄTNING AV LJUDIMMISSION FRÅN VINDKRAFT. VIDAREUTVECKLING AV METOD FÖR MÄTNING

The Swedish government have a goal that wind turbines shall produce 30 TWh by the year 2020, compared to about 3,5 TWh produced in Sweden during 2010. To minimize the disturbance that wind turbines create the Swedish Environmental Protection Agency has stated a guideline value that noise from wind turbines at nearby residents shouldn?t exceed 40 dBA, at 8 m/s wind speed. With advanced calculation models, like Nord 2000, the emitted sound from future wind turbines can be calculated at an early stage to optimize the power production without exceeding the 40 dBA. When the turbines have been built there is a need to verify that they really are within the guideline.

Utomhuspedagogik : Lärares tankar och erfarenheter av utomhuspedagogik

Abstract This research is about outdoor education as a pedagogical method, and its purpose is to find out six teachers thoughts about outdoor learning, and their experiences about this method.Many philosophers and advocates for the outdoor education claims that learning is best acquired when children uses all their senses and that school subjects that are thought in the classrooms also can be thought outdoors.  Studies have shown that children´s health and learning ability increase when they are thought outdoors.Interviews and observations have been done.My questions are: How do the teachers practice outdoor education in their classes and what is the result? Which subjects do they use in outdoor education? Do the teachers see any obstacles using the outdoor method and why do the not use it to a greater extent? Keywords: Outdoor education, outdoor mathematics, learning and effects, children, thoughts and expiriences. .

Behövs kommunal fritid?: en kritisk diskursanalys om fritidschefers egen syn

Uppsatsen hade som syfte att belysa om kommunal fritid behövs. Undersökningen bestod av samtal med fyra fritidschefer på deras fritidskontor. Samtalen tolkades hermeneutiskt och analyserades med Faircloughs kritiska diskursanalys (Winter Jørgensen & Philipps, 2000). Som teori utgicks från Habermas diskursteori (Habermas, 1995). Analysen visar att kommunal fritid är stadd under stark förändring och har gått från "inte" till att "vara".

Aktuariella vinster och förluster : Valet av redovisningsmetod enligt IAS 19 samt borttagandet av korridormetoden

Background to problem: Pensions play a big role in people's lives when life expectancy continues to increase. Companies can choose different ways of reporting their pension plans, and within the defined benefit pension plan poses the actuarial gains and losses that can be reported based on three different methods. Only one method will exist from 2013, how will the companies that use the other two handle the new situation?Purpose: Investigate why different companies have chosen to report its actuarial gains and losses along the corridor approach, directly against income or directly in equity. How will the companies that use the corridor method manage the situation when it will only be allowed to report in other comprehensive income as of 2013 and how will this affect them.Methodology: Data was collected through qualitative questionnaires sent to companies listed on Nasdaq OMX Nordic Stockholm, Large Cap and Mid Cap, and a qualitative interview.

Inventering av röjningsobjekt från helikopter :

In time with HolmenSkog district Egenskog Norrköping´s decreasing mountain of cleaning, the office started to look around for new alternative cleaning strategies to lower the costs connected with cleaning. One option was to make the inventory strategy more effective and after a phonecall with the head of the district, Jonnie Friberg, the planning started to try inventory in pictures taken from a helicopter. The pictures was at last taken from a digtal camera and the vegetationheight was mesured with a laser. The gear was supplied from Kallax Flyg AB, Luleå. In the trial 15 stands was selected depended on age and different mixtures between pine (Pinus sylvestris), spruce (Picea abies) and birch (Betula pubescense and Betula pendula).
