Nostalgiska Ljud

Det finns ljud som är på väg att försvinna i takt med teknologins utveckling. Dagens ungdomar har aldrig hört ljud från den äldre teknologin, som den äldre generationen har fått växa upp med såsom skrivmaskinen, modemet m.m. Dessa produkter gav ifrån sig ett speciellt ljud som numera inte hörs lika mycket idag. Men vad händer när tekniken utvecklas till den grad att ljud blir en säkerhetsfråga? Förutom teknikljud finns det ljud från förhistoriska och nyligen utdöda djur som forskare har lyckats återskapa genom studier av kvarlevornas anatomi.

Skattereduktion : Bör arbetskostnaden regleras i lag

The Income Tax Act is enacted what criteria must be met to obtain a tax reduction of household work. Household work is the common term for ROT- and RUT-works. The purpose of the tax reduction is to increase job opportunities and to discourage that undocumented work performs.It is only for the labor cost as tax reduction is given for. The concept of labor cost is defined in law as it is not comprised of cost of materials, equipment or travel. The preliminary work provides no closer explanation what the labor cost includes.

Utvärdering av den biologiska reningen av processavloppsvattnet vid GE Healthcare i Uppsala

GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity. Therefore it seemed necessary to evaluate a newly installed biological process technique, which is the background of this thesis. The evaluated biological treatment process was built in 2003 and consists of a biological reactor filled with moving bed carriers with a high surface area for biological growth. At the time of the project the biological wastewater treatment plant consisted of a flow equalization facility and two following parallel biological processes; a biological reactor with moving bed carriers and a tower trickling filter.The aim of this thesis was to survey the function of the biological reactor with respect to the reduction of organic matter.

Bullerreduktion av hytt på Volvodumprar : Undersökning, mätning och analys

Too high levels of noise lead to various health problems and cost society billions of SEK peryear. In this thesis we have examined a model of the A40E articulated hauler at VolvoConstruction Equipment in Braås. We have tried to reduce cabin noise in an articulated hauler,while also providing a way on how to proceed with a machine when the cabin does not measureup to the sound requirement. The best way to find leaks were with a reference source of model4205 and its speaker HP 1001 from Brüel & Kjaer in the cab and then walk around and listen towhere the reference source was more prominent. In this way, we found that the edges and theplugs were sensitive areas.

Minimiaktiekapitalet i Sverige: En konsekvensstudie av ett slopande av aktiekapitalkravet

In 2007 the Swedish government appointed a commission of inquiry with the task to submit a proposal of reduction in the requirement of a minimum legal capital for private limited liability companies. The commission of inquiry?s main proposal involved a reduction to SEK 50,000 compared to the prevailing SEK 100,000. Following a complementary proposal from the Justice Department suggesting a reduction to SEK 1, this paper aims at providing an understanding of the function and purpose of a minimum legal capital and the consequences that follows from an abolition of the statutory capital requirement. The thesis concludes that the legal capital?s main purpose is that of a standard contract internalizing the shareholder?s risk in business.

Mating behaviour and hierarchy among male warthogs (Phacochoerus africanus) in Kenya

Warthogs live under natural conditions in matriarchal groups, bachelor groups and yearling groups. Just like all pig species do warthogs have a complex behaviour repertoire. The semi-wild warthog population at Kichwa Tembo Lodge, outside Masai Mara National Reserve, lives in a fenced area with access to food all over the year and is protected from predators. The aim of this study was to observe the male warthogs? mating behaviour and their hierarchy during the mating season.

Ordermusiken

This thesis strives to demonstrate my increasingly phenomenological approach to musical composition in relation to the extensive body of musical works connected in different ways to the poetry collection ORDER by the Swedish author and play-wright Lars Norén. The hand, the touch, the voice, the space (environment) and its philosophical implications are scrutinised from a poetic perspective (my poetics). The question of language (the word), the sign (text), sound/noise/music and its immanent bodily qualities are focused and questioned in my own work as well as in primarily two case studies of the music of Pierluigi Billone (1960-) and Morton Feldman (1926-1987).The text reflects the emancipatory process my music has undergone the last 4- 5 years: moving away from language and text (representation) to body and sound, although preserving and nurturing the extended idea of the sign (as signification of sound and body) as a possible embodied vehicle in my composing and artistic thinking.The reader is invited through the extensive use of sketches and work methods to witness and follow this process as a manifestation of the ?doing? rather than the presentation or construction of an analysis in an academic sense.The thesis offers no solution and it fails to encapsulate all of the so-called ORDER-MUSIC (the music that is connected with Norén's collection of poetry) Instead it proposes a possible way of ?opening? the process to a basically phenomenological methodology inside the musical field of score based chamber music..

En studie i realtidsgenererat binauralt ljud

Många av dagens dator och TV-spelsljud är anpassade för högtalaruppspelning, i många fall även flerkanalssystem som 5.1 surround och liknande. Få spel är anpassade för uppspelning genom hörlurar och för att få en bra ljudlokalisering i hörlurar behövs ofta någon form av surroundhörlurar. Vi tror att man kan skapa trovärdig (Riktnings)återgivning av ljud i hörlurar genom bara två ljudkanaler genom så kallat binauralt ljud. Vi kommer i detta arbete att beskriva de faktorer som spelar roll i vår stereohörsel, varför de fungerar samt vilka svagheter som finns i detta system. Vi kommer att skapa ett system för att behandla realtidsgenererat binauralt ljud för spel och beskriva de verktyg vi valt och den generella arbetsprocessen.

Optimal högtalarplacering i en lastbilshytt

This Degree Project was about finding the best loudspeaker placement in a heavyweight truck and also the best suited loudspeaker for this task. The project took place in Södertälje, Sweden, on behalf of Scania CV AB. The goal was to create a new listening environment in a truck cabinet.The results were accomplished by the performance of a few different tasks. First a benchmark was made on Scanias top competitors. Second a listening test was made to get an apprehension of what people find lacking in the sound reproduction of the sound system.

Kostnadsbesparingar på EM7 : Omkonstruktioner för billigare tillverkning

This thesis describes how a cost reduction project was done on the Packsize ondemand packing machine EM7. The cost reduction was achieved by making minorredesigns of the EM7.The project began by studying the EM7´s structure and function by working on itsassembly line. A short literature study on the subject Design for Manufacturing wasalso done.By working on the assembly line and by speaking with staff from production anddevelopment departments, a number of ideas for reducing manufacturing costs arose.Estimations of the potential cost reduction size for each proposal were done incollaboration with vendors and the purchasing department. Based on the size of the cost reduction, technical risk, impact on the assembly lineand the development time the various proposals were ranked. The two highestranked proposals were selected for further development towards finished solutions.One of the ideas that were selected to develop in to a finished solution meant thatsome of the pneumatic valves were replaced with others.

Reduktion av föroreningar i processvatten från en äggfabrik i Brasilien : Kväve- och fosforrening i anlagda våtmarker.

A water treatment unit consisting of two aeration basins, two settling tanks, a residence basinand a horizontal subsurface flow wetland were used to treat wastewater from an eggprocessing factory in Brazil. The aim of this paper was to determine the efficiency of thesystem in reducing nitrogen, phosphorus, BOD5 and TSS (among other parameters) andgetting a further understanding on different kinds of constructed treatment wetlands as well astheir nitrogen and phosphorus removal processes. The wastewater from the factory consistedof process water from manufacturing and water used for cleaning, no stormwater or sewagewater entered the system. Tests were taken three times a month from October 2013 ?til April2014.

En studie av etiken bakom australiensisk missbrukarvård enligt harm reductionmetoder

Syfte: Syftet med vår uppsats är att belysa den etiska dimensionen av harm reductionanknuten missbrukarvård. Till vår hjälp har vi haft etiska teorier och sociologen Zygmunt Baumans begrepp. Frågeställningar: Vi har använt oss av två huvudfrågor som vi därunder bryter ner i konkreta frågor. 1 Hur ser de etiska resonemangen ut hos personal verksam inom harm reductionanknuten missbrukarvård?Vilken typ av etik använder de sig av? Har de centrala etiska principer, vilka? Hur ser de på etik och moral? Följer de etiskt formulerade regler? Hur ser de på prohibition? Hur ser de på drogbruk? Hur ser de på människan? Vad driver dem i deras arbete? Hur ser de på harm reductions påverkan på samhället?2 Hur kan man förstå harm reductionmetoders framväxt ur Baumans sociologiska perspektiv?Hur kan harm reductionmetoder kopplas till det senmoderna samhället? Hur kan harm reduction rättfärdigas etiskt utifrån ett sociologiskt perspektiv? Hur kan harm reductions förklarar sociologiskt? Vilka förutsättningar fanns för att harm reduction skulle kunna utvecklas? Hur kan Baumans begrepp förklara harm reductions ställning i det senmoderna samhället? Metod: Vi har använt oss av en kvalitativ metod med intervjuer som redskap.

OMBYGGNAD AV TRAFIKPLATS : Ekhagsmotet i Jönköping

We have the tradition in Sweden to build villas and houses with a wooden framework. It has become natural for us because we have so much forest in our country. Building with wood has advantages, it is easy to process, but also disadvantages, as it is sensitive to moisture.Finland has long made use of the thermal blocks to build villas. It is a type of bricks that are a bit like a sandwich element, with a core of EPS and concrete on both sides of the core material. The concrete is hollow, so that after the walls has been bricked up you pour concrete into the hollow bricks.The issue of this report is to find out if concrete can be an alternative to wood as framework material in villas.
