This project is about development of virtual drums for iPhone and iPad. The project aims to provide the company Toontrack AB with a good foundation to build drumbased apps. The focus has been on getting a quick response when playing and that user interfaces should be easy to use, intuitive and customizable. The result is impressive and both audio and graphics are of excellent quality thanks to good collaboration with Toontrack, that previously has developed drum-based software. The drum kit offers a variety of articulations and even the ability to play various dynamics, although the screens are not pressure sensitive..

By transcribing one drum solo recorded and performed by myself and another performed by Philly Jo Jones, a drummer I?ve heard and listened to through out my life, I try to find answers to the question: How much are we influenced by the music and the musicians we listen to?My experiment starts with me recording a improvised drum solo and then transcribing it. Then I found and transcribed a drumsolo by Philly Jo Jones that I had not heard before. The results of these experiments showed some interesting similarities between my own playing style and Philly Jo Jones and I learned a lot about what stuck with me from listening to him playing, and what didn?t..

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..

En studie i hur man kan arrangera, spela in och mixa slagverk i rollen som trumset. Artisten Nasimiyu Murumbas andra album Dig Deep innehåller en låt med trumset, Raise Your Arrow. Övriga har slagverk som täcker upp funktioner som trumsetet har. Processen beskrivs ur producentperspektiv med redovisning av arrangemang och analys av Raise Your Arrow samt tre av albumets övriga låtar, Free Ones, Dig Deep samt The Biggest Drum. Dessa analyseras från tre utgångspunkter: arrangemangmässig, konstnärlig och teknisk.

In this thesis you will be able tofollow the design work of a drumtest. A tool that by having a rotatingdrum with equally positioned obstacleswill simulate the conditions a mountainbike rim will pass through.Initially there is a specification ofsome parameters and requirements thatthe design had to fulfill. There is alsosome brief background information aboutwhy a drum test is required for abicycle rim manufacturers and about thecompany Innolite Design AB that thisthesis is done for. After that itfollows an extract from conceptgeneration with the chosen concepts andsolutions but also some of the conceptsthat were not chosen.The thesis also contain a part where thereader cangain a deeper understanding of how thedesign works as well as some moredetailed facts about how the choice ofmaterials, their thicknesses, etc. havebeen made.

Syftet med den här uppsatsen är att redovisa för de effekter som kan sespå odlingssystem samt livssituation hos småbrukande bönder i Östra Afrika efter ett införande av en liten biogasanläggning kallad "floating drum". Anläggningen genererar rötrester som används som gödslingsmedel i odlingssystem och biogas som bränsle i matlagningssituationer. Resultatet baseras på uppgifter från litteratur, fältstudier och en enkätundersökning. Uppsatsen har sin utgångspunkt från en fältstudie hos en småbrukande familj på landsbygden. Studien genomfördes i ett område som heter Kadongo och ligger i nordvästra Kenya.

The purpose of this project is to get a fully functional, automatic steering system and a variable breaking system with an emergency breaking function to an off road vehicle. This off road vehicle is supposed to work as an aid in military situations. A team of two, Sebastian Attervall and Nichlas Gustafsson, got an order from Jonas Nyårds and the PreeRunners Project to construct a steering system that could manoeuvre an off road vehicle without any human involvement. To make this possible the vehicle would be guided by onboard sensors, cameras and computers. The team where also assigned to construct an automatic breaking system, there also no human would be involved.

This final thesis aim to create a support that can decrease the uncertainty when planning the cable drum flanges lines that produces cable drums in the interval 100 to 320cm in diameter at Vida Packaging in Hestra. The purpose attains through finding an optimal batch size that minimizes the total storage cost and order prime cost, without degenerate delivery capacity to the customer. Through survey the sale and stock balance development during 2005 and 2006 for cable drums in Hestra and give alternative suggestions how to plan the production after installing a new cable drum flanges line. The study also explores different ways of working during product change in existing nailing line, to minimize the order prime cost. Vida Packaging in Hestra is a part of the Vida group, which is Sweden?s largest privately owned sawmill group with seven sawmills placed all around southern Sweden.

The continuous process of urbanization results in demands on research and development for ecological and sustainable city development. Because of this, the current systems for wastewater treatment may have to be improved. In order to evaluate new technologies for municipal wastewater treatment, a development project has been initiated for the new district Hammarby Sjöstad in Stockholm. The project is lead by the company Stockholm Water. High environmental standards have been put up for the district, as it must be twice as good as an ordinary new district.

The thesis in product development ? mechanical design includes 15 credits and was carried out during the spring of 2014 at Semcon in Eskilstuna. The task is to construct a special machine for positioning and orientation of a key blank found in six different shapes, the construction is a part of a larger machine for encoding the key blank where a pick- and-place device or robot pick up the key blank and deliver it further in the process. The entire construction is designed for ASSA OEM Gothenburg.In order to accomplish the project the first step was to analyze the existing solutions to similar problems on the market in a current situation analysis to create an understanding of the problem. This was followed by a flow analysis and a functional analysis to get a deeper understanding of the problem and structuring the machine's process flow and its features.

Syftet med arbetet är att ta reda på hur trummisar kan lösa mentala blockeringar i sitt musikutövande. I mitt arbete vill jag belysa vikten av expressivt spel och vikten av mentala aspekter i musikutövandet. Det är viktigt att arbeta med mentala "övningar" precis som det är viktigt med praktiska övningar. Musiker värmer ofta upp fysiskt inför en spelning men hur många värmer upp mentalt? Mina forskningsfrågor är: - Hur kan man påverka trumsetselevers musikaliska utveckling med hjälp av expressiva och mentala övningar? - Vilken roll spelar mentala övningar och förberedelser för professionella trummisar? Jag har intervjuat två etablerade trummisar och trumsetslärare, en vid musikhögskolan i Malmö och den andra en verksam trummis i Stockholm och före detta lärare på Musikhögskolan i Malmö.

This is a study of the way power relationships change when women start to play candombe in Montevideo, Uruguay. Candombe is a type of music, which is traditionally played by men within the black minority in the country. This study has been done with an intersectional point of view, taking the social categories gender, class and ethnicity in account. The method used was participatory observation in a field study made in Montevideo between November 2008 and February 2009.This study?s main conclusions are that the power relationships change with the participation of women in candombe in several important ways: The women legitimize an alternative way to be a woman when they take the men?s role as a drum player.

This report is the result of a thesis as been implemented during the spring term 2009 atthe University of Gävle.The company Bruks produces mobile chippers which are used for chipping loggingslash, roundwood and parts of trees. The chipper is powered by a separate diesel engineand the chipper can be assembled on trucks, trailers or some other carrier vehicles.When the chip has passed the chipper drum, the chip is collected in an integrated binwhich is mounted on the vehicles frame with dumping yokes. When these dumpingyokes were designed they were probably created with large material dimensions. Theaim with the degree project is hence to study the strengths of materials and, if possible,to suggest an arrangement that can decrease the total weight on the dumping yoke onBruks´ mobile chippers 805 CT.The CAD-program Pro/ENGINEER was used during the project for outlining the 2Ddrawings,as distributed of constructors on Bruks, to solid 3D-parts. The three-dimensionalassembly from Pro/ENGINEER was transferred to Pro/MECHANICA.

Studiens syfte har varit att, utifrån ett lärarperspektiv, bidra till ökad kunskap om hur IKT används i textilslöjden och hur förutsättningarna för detta ser ut. Avsikten var främst att ta reda på hur lärare använder sig av de resurser som finns på skolorna och i sina klassrum men även vad de skulle önskat att de hade tillgång till. Studien gjordes på några mellan- och högstadieskolor runt om i Sverige och datamaterialet insamlades genom kvalitativa intervjuer med fyra stycken verksamma textillärare. Fokus i intervjuerna var att finna positiva och/eller negativa aspekter med digitala verktyg i textilslöjden, hur lärares undervisning förändras, samt om slöjdens arbetsprocess förändras vid arbete med digitala verktyg. Resultatet visade att de intervjuade lärarna använde sig av IKT olika mycket men har många liknande tankar kring att det är tidssparande, inspirerande och utvecklande för eleverna att arbeta med i olika sammanhang.
