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.

In today?s modern society with high-speed connections covering the globe people are more than ever finding themselves gazing into the cold lights of the computer screen. On the other side a strange and exciting world yet to be explored awaits. Many are those who spend hour after hour running over green hills swimming in vast blue oceans in the lands of Azeroth, the playfield in the MMORPG game World of Warcraft. In media we often read and hear alarming reports on players stuck in this virtual world, ceasing to play a part in the real world.

This study aimed to investigate whether lambs show anticipatory behaviours in a holding pen prior to entering a known arena, whether the holding pen experience prior to the arena exposure affects their play expression in the arena and whether their behaviour (in home pen) is affected if arena access is denied. Twenty pair-housed male lambs (average 14 weeks old), were exposed, in chronological order, to five treatments. Holding pen treat-ment (HP-control): Each pair was led into a holding pen (2.7 m2) and remained there for 5 minutes before returning to their home pen (6 m2). Holding pen ? arena treatment (HP-A): Each pair was led into a holding pen for 5 min and then was allowed access into the arena (22 m2, containing two hanging chains, one ball and one platform) for 15 min before re-turning to their home pen.

The purpose of this study is to illustrate the impact on children's development around playing and how significance the formation of the schoolyards is focusing on how it inspire and calls to play within the children's. The study will also show how the youth workers experience the schoolyards and how they can incorporate the playground in their work to inspire the children's play and activities. The methods used in this study is based on both real conversations and by mail with educated youth workers and observations. The results shows that the schoolyard environment is very important for the children's play and development. The study reveals the importance of having nature like forest nearby and that the environment should be suited for everyone.

This social psychological qualitative study demonstrate how the children?s play begin and what significant important it has in the child?s identity progress. The main subject in this social- psychological study is the child?s self and how through imagination, creativity and spontaneity the human?s personal identity is discovered. However the study is based upon the children?s plays in day- care, the children whom are being objects for the study are from 3-6 years old.

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.

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.

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.

AimThe aim of the study was to develop a method for the survey of play movement demands and temporal patterns in order to enable a descriptive study of the defensive players in American Football. The overall aim was to  improve the understanding of how American Football is played to create opportunities for enhancement of current or developing new training methods to better suit football.MethodFifty plays from a Division 3 college football game on video from 2005 was divided into sequences of action for one player each from the defensive line, linebackers and defensive backs and analyzed with the video analyzing software cSwing. Every players sequence of action was recorded in a spreadsheet and noted on a scaled football field where distances were measured and together with time stamps from cSwing velocity was calculated.ResultsUsing this method it was possible to describe the play movement demands and temporal patterns which was the main task of the study. The defensive end worked on an average 4.61 seconds per play, the distance was 12.4 meters and average speed 2.5 m×s-1. The linebacker worked on an average 4.35 s per play, 13.7 m and at a mean speed of 3.0 m×s-1.

The purpose of the study is to contribute to the field of social access in children's free play in the pre-school class, by looking at how children are included and excluded and how power structures arises in the free time. In order to capture the events that occur among the children, observations were chosen as research method.The results show that the children wanted to play with each other, and that the most common way to facilitate play was to ask "Can I join?". There were also other strategies being practiced regularly. It was also common to exclude other children from playing, and this was especially when the children wanted to protect their ongoing game, or that someone was not allowed to join because he or she ruined it for the others.

Stage Design is design for action and contains décor, side-scenes and properties, as well as costume and grease-paint. The one responsible for this is the Stage Designer, who together with the Director, creates the best conditions for the actors to perform in. The stage, where the play takes place, could be either in a theater, an auditorium, or in another sort of room, at another place, inside or outside, and where the place itself inspires to theatrical performance and expressions. This type of theater is called Site-specific theatre. Two examples of this is the workshop ?Skogen sjunger? (eng.

The purpose of this essay is to examine the impact on children playing at a preschool yard that is designed with traditional playground equipment, and a nature-like yard without traditional playground equipment. How these respective environments influence children?s play, which other factors in the external environment that affect the game and whether the theories in the literature correspond with the results were important questions for the essay. To answer these questions a case study was applied onto two specific preschool centers, both located in Malmö. Through literature studies, inventories, observations and interviews with staff and children, a picture become clear of how the children use the yard and how their play is affected by the design of it.

Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.
