The purpose of this Master's thesis is to determine which of the three general classification schemes, DDC, SAB, and UDC is the most appropriate for classifying music documents. This is done by analysing and classifying 60 music documents such as recordings, scores and books about music. The codes resulting from the classification are analysed according to a number of evaluation criteria based on classification theory. The criteria focus on the systems specificity, exhaustivity, exclusivity, helpful sequence, hospitality, notation and that related classes are kept together. The study showed that the systems specificity in classification was of great importance in classifying music documents because of the diversity of music genres.

Each year, the coffee machines at Ericsson in Kista produce around 100 tons of ground coffee waste.The companies Coor Service Management, Löfbergs Lila and Selecta are all responsible for differentstages in the logistical chain in delivering coffee and, together with Ericsson, they want to increasetheir environmental benefit. The plan is to produce biogas through anaerobic digestion instead ofincinerating the coffee waste in a heating plant. The results are to be presented as different businesscases in which different biogas plants are compared with the reference case (heating plant),comparing costs and environmental impacts.There are two major environmental benefits from producing biogas; reduced carbon dioxideemissions from when fossile fule is replaced by carbon neutral biogas, and reduced emissions fromreturning digestate from the bio reactor to farmland instead of using industrial fertelizer.In order to determine the biogas potential in coffee waste, a couple of properties had to bedetermined in a laboratory. Properties such as the dry substance content, heating value, moisturecontent and ash content. The results show that 100 tons coffee waste could produce around 16 500Nm3 biogas which would contain 163 MWh.The biogas reactor and upgrade plant both need energy gas to function and uses around 14 MWh ofthe produced gas.

The aim of this paper is to examine how The Swedish Library Classification System, also known as the ?SAB-system?, has classified popular music. The investigation is limited to the classification category of ?Yx Jazz, Rock and Popular Music? within the SAB-system. The development of this category is studied.

To fulfill the climate target that EU and the Swedish government have decided to apply, it becomes increasingly important that the energy efficiency of existing buildings and making new buildings energy efficient as possible. Of Sweden?s total energy consumption in 2011 was 40% used by residential and service. Of the 40% of the energy consumption was 60% used for heating and domestic hot water. A report from year 2012 shows that one reason why the heating volume is so great could be due to underestimating on the energy consumption for the heating in the planning of the building.

During the past 30 years the fuels for energy production in heating and power plants have changed. Fossil fuels have decreased in usage whereas bio fuels in Sweden have increased with 60% since the 1970's. Different fuels affects combustion and the release of various substances and particles into the flue gas. This is caused by the diverse components and chemical structures of fossil fuels and bio fuels. When the flue gas leave the combustion chamber and enters the path to the chimney particles in the gas are being transported out of the combustion chamber.

A patient simulator for testing anaesthesia machines has been developed at Maquet Critical Care AB, to reduce costly and time-consuming experiments on animals. The device simulates human lungs regarding lung dynamics and volume, uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on the simulator are durability and size; the device shall be compact enough to be moveable.The resulting simulator fulfils the requirements and enables better repeatability and ability to test extreme cases than experiments on animals do.Uptake of the anaesthetic agent is achieved in a active carbon filter and controlled by regulating the flow. The flow is created by a regenerative blower and controlled using a proportional valve. The uptake can be set by the user or by a simple uptake model modified to recursively handle changes in the concentration of anaesthetic agent.Carbon dioxide is fed into the system from a tank by a mass flow regulator.

The housing sector uses 40 % of the energy in Sweden and half of the electricity usage. Theuse of energy is the main reason to the increasing rate of carbon dioxide in the atmosphere.This is the main motive but also a wish of higher safety, that is a higher rate of selfsufficientenergy production in Sweden, we want to decrease the need of using fossil fuel. Now whenthe energy price rise, the interest in energy issues increase and more people discuss thepossibility of reducing the usage of fossil fuel. A change to renewable energy such as sun,wind and water is the only solution where we can get a sustainable development.One way to contribute to a better use of energy is to build in the principle of passive house.The house is being built with a thick and tight insulation. If you use a heat-exchanger withhigh degree of efficiency and a final heating battery on the ventilation system, the heat fromlamps, devices and the ones living in the house should be enough to fulfil the criteria ofliving.

SammanfattningEn ånganna monterades i EGR (Exhaust Gas Recirculation) slingan på en 12,7 liters Scania Euro V motor (DC1306). En modell som beskriver Rankine cykel togs fram med vatten som köldmedium i simuleringsverktyget GT-Power. Ångpannan i GT-power modellen kalibrerades m.h.a experimentell data.Simuleringarna visade att det optimala ångtrycket, det trycket där högst effekt kan erhållas från expandern, är beroende av EGR temperaturen. Det innebär att ju högre EGR inloppstemperatur desto högre optimalt ångtryck. EGR temperaturen i punkt 2 i ESC cykeln är 514? C för denna motor, vilket resulterar i ett optimalt tryck på 120 bar enligt simuleringen.

The housing sector of today represents for almost 40% of the energy consumption, an energy consumption of which the major part consists of non-renewable energy sources. This is not sustainable and utilization of new energy-efficient technologies in buildings can be a step in the right direction, towards a sustainable energy society.This report has been made on behalf of and in cooperation with Älvstranden Utveckling AB in Gothenburg to examine how future energy-efficient technologies can affect the energy demand in energy-efficient multi-dwelling buildings.The report is based on Älvstrandens passive house, Hamnhuset, a house whose energy consumption is far below the BBR's requirements. The report looks at the opportunities for improvement within windows, insulation, solar energy technologies, as well as white goods. Computer simulations are then made to apply the selected technologies into a reference building. Technologies are selected from an energy efficient perspective and no account has been taken of other aspects such as the economy.

In the following study I probe the social world of hard-rock music. By conducting interviews with four young male enthusiasts of this music I try to develop a general picture of this social world, as well as of the basic elements on which this particular subculture is constructed. The identity of a hard-rocker is based upon a number of factors beyond just a preference for that music. Throughout the interviews I encountered many implicit norms that one must followed in order to be able to see oneself as a true hard-rocker. I also found that from the respondents? perspective, the mainstream culture has, throughout the history of metal music, used various ways to counter the spreading of this genre.

Vid studioinspelning av pop- och rockmusik bearbetas musiken ofta i efterhand. Det går att klippa i spåren, skapa loopar, lägga på instrumentspår i efterhand, lägga på effekter och mycket mer. Ett låtarrangemang kan lika gärna skapas vid mixningsprocessen i studion som i replokalen. Detta kan skapa en problematik när musiken sedan ska framföras på konsert. Vad gör man till exempel när en låt spelats in med åtta pålagda gitarrspår i studioversionen, men bandet bara har en gitarrist när den sedan ska framföras vid konsert? Jag har undersökt vilka problem och möjligheter som finns i ?översättningsprocessen? när studioinspelad musik arrangeras för livekonsert.

Uppsatsen undersöker hur de olika panoreringsteknikerna, direkt/ambient och direkt-överallt, för 5.1 surround uppfattas utav lyssnare. Enligt direkt/ambient ska alla direkta källor panoreras till frontkanalerna (L, C, R) och endast ambiens finnas i surroundkanalerna (Ls, Rs). Enligt direkt-överallt kan direkta källor panoreras till alla kanaler. Ljudstimuli i tre genrer har utav undertecknad framställts, rock/hårdrock, jazz/fusion och hip hop. Ett exempel enligt direkt/ambient och ett enligt direkt-överallt framställdes i varje genre.

In developing countries such as Vietnam the population consumes more animal products for example milk and meat than before which requires greater livestock production. Ruminants contributes to more methane emission which creates a dilemma between food production and its environmental impact. By feeding ruminants with nutritive crops which humans can not assimilate the animal performance will increase in terms of better growth and milk production without inpinging on food that can be consumed directly by humans. Increasing animal performance reduces methane emission in terms of amount of methane in kg-1 milk and meat which today is much greater in developing countries than developed countries. The aim of the study was to investigate tropical tannin-rich legumes for their potential as a feed supplement for ruminants made in vitro.

Syftet med den här uppsatsen är att studera om den nya Arenan kan komma att vara en bidragande faktor till säsongsförlängning i Kalmar. Eftersom den nya Arenan inte ännu är färdigbyggd, vill vi undersöka beslutsfattares syn på projektet samt hur ett sådant projekt kan komma att påverka Kalmar som destination.För att kunna studera verkligheten, utan att styras av redan befintliga teorier, valde vi i vår studie att använda oss av en induktiv ansats. Den större delen av vår datainsamling grundas på kvalitativa intervjuer, vilka vi kompletterade med diverse rapporter och skrivelser på hemsidor.Vår slutsats i den här uppsatsen är att den nya Arenan kan bidra till säsongsförlängning om verksamheten maxas. För att detta ska vara möjligt bör samtliga beslutsfattare börja spela i samma lag, klara och tydliga mål med projektet måste sättas upp och fokus bör läggas på hur ett projekt av den här storleken kan gynna hela Kalmar som destination, inte enbart en av de inblandade aktörerna..

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.
