Syftet med detta examensarbete är att utveckla en datorlaboration baserat på aktiv ljudreglering för kursen reglerteknik allmän kurs för maskin och farkostteknik vid Kungliga Tekniska Högskolan KTH. Arbetet ska innefatta en utveckling av en matematisk modell av rörsystemet som ska regleras med en lead-lag regulator. Rörsystemet vid Marcus Wallenberg Laboratoriet ska användas som modellsystem, och den matematiska modellen ska baseras på mätningar insamlade på detta system.Den matematiska modellen skapades med hjälp av ett s.k. identifieringsexperiment och identifieringen baserades på en viktad minsta kvadratanpassning av insamlade frekvensdata. Modellen anpassades till en överföringsfunktion som visade sig ha ett nollställe i komplexa högra halvplanet, vilket motsvarar en svår bandbreddsbegränsning för den aktiva ljuddämpningen.

I den här slutreflektionen kommer ni att kunna läsa om vårt kandidatarbete i sin helhet. Ni får ta del av det koncept vi arbetade fram och strävade efter att realisera. Ni kommer att få följa med i arbetsprocessen där vi låter er få inblick i hur vi gick från idé till färdig produkt inom de tre avdelningarna programmering, grafik och ljud. Avslutningsvis kommer vi att reflektera över kandidatarbetstiden, både som grupp och på individnivå. Några av de frågeställningar vi tar upp handlar om hur vi har lyckats genomföra projektet trots bristande planering och utan någon hierarkisk ordning samt hur det har varit att arbeta i en grupp där majoriteten av medlemmarna har haft en ny roll för första gången i ett projekt.

Syftet med denna uppsats har varit att få en inblick i hur pianot används inom den svenska folkmusiken. Bakgrundskapitlet handlar om folkmusikgruppernas och instrumenteringens utveckling inom svensk folkmusik. Jag har intervjuat tre aktiva folkmusikpianister och lyssnat på och analyserat deras spel. Det följer även med en cd-skiva med ljudexempel från intervjutillfällena. Vi pratade om karaktärsdrag som de lyfter fram i spelet, om deras inställning till folkmusiktraditionen, pianots möjligheter och begränsningar samt vilken roll pianot har i den svenska folkmusiken.

The Swedish government ratified on May 1 2009 an amendment of marital law, resulting in same-sex marriage becoming legalized. With the rights of the Christian Swedish state church to officiate weddings originating from the same law, the church was thereby faced with two options: Either officially include same-sex couples in the Christian concept of holy matrimony and keep the right to officiate weddings; or give up the right to officiate weddings altogether. An official decision to accept the terms was reached on October 22 2009, but not without being preceded by an agitated medial debate.This research attempts to analyze the arguments of the debate in three stages: In the first stage the arguments are categorized according to their respective ideological standpoint. In the second stage these categories are examined from post-modern, social constructivist and socialization theory perspectives. Based on this, the third stage sees the arguments analyzed from a viewpoint based in the Copenhagen school concept of securization.The research concludes that the debate does not only simply feature two sides with differences of opinion; but rather that the arguments of the two opposing sides are founded in a common view of the other side as a fundamental threat to ones conception of a sound society..

In the last few years the environment becomes more watchful, even for us farmers. All agricultural enterprises that exceed 200 animal units must be tested according to regulation of environment. A farm business with 200 animal units and more is classed ?environmentally hazardous activities? and has to make an environmental impact assessment for the business you have today, and the activity after expansion. Before you can construct a building and expand the numbers of animals is a lot of applications to make. I have in this project restricted me to establish a environmental impact assessment and a consultation foundation. To make a environmental impact assessment is the big part of the application. The environmental impact assessment take a lot of time and you need skills for all the rules in the environmental code to be abele to make an environmental impact assessment approved. The environment codes purposes (1 kap 1 § Miljöbalken) is to rule the laws. The purpose of the environment code is to promote sustainable development which will assure a healthy and sound environment for present and future generations. Definitions of a ?environmentally hazardous activities? 9 kap 1§ Miljöbalken) shall mean the discharges of wastewater, solid matter or gas from land, buildings or structures onto land or into water areas or ground water.

Pet rabbits are increasing in popularity and the owners want the same treatment for them as they would want for a dog or a cat. However, the knowledge among clinical staff about these small animals is not always up to date. The aim of this paper is to highlight the needs of the pet rabbit and how these can be met regarding veterinary nursing. Pet rabbits are different from dogs and cats in several ways and their needs as patients differ as well. Rabbits are herbivorous prey animals. To avoid predators, they are very reluctant to show any sign of weakness for as long as they can.

This report describes a study of how the teachers in Sweden are working with the dialog in their classrooms. The aim was to find out how the teachers are using the dialog in their teaching. And if they think that the dialog has a meaning for the pupils learning, and how they think the pupils learn. Even the difficulties whit the use of dialog in the classrooms and which in the classroom should speak the most was examined. The methods that I used in this qualitative report were interviews and observations of four teachers in the primary school.The research questions in this report were:Which meaning do the teachers think that dialog affects the pupils learning?How does the teachers work whit dialog in their classrooms?Who is leading the dialog in the classroom?Which are the difficulties when working with dialog in the classrooms?I found out that the teachers view on knowledge belonged together with how they worked with the dialog.

The first company to send TV-commercial was the American company NBC, it was in the year of 1941. In Sweden, TV-commercials were first shown in 1987/88. TV 4 was the first channel to send commercial in Swedish television.TV has the advantage of showing both sound and picture, which makes TV the strongest channel of communication to mediate a message between a company and the consumer. Although TV-commercial is the most expensive choice to mediate a message, it is also the most effective one. (Persson, 1993)Almost everyone is exposed to TV-commercial daily.

The aim of this bachelor thesis is to find out how young adults experience the library and the space that they have access to. I used semi-structured interviews to find out about this and interviewed eight youths between the ages of 15 and 18 in a medium sized city in the province of Västra Götaland in Sweden. I then analyzed the material with the help of Goffman?s theory about front stage and back stage. I also did a small comparison with results from previous studies.The result showed that the youths generally liked the library and the staff but they had opinions on some issues.

As a guitarbuilder it is an advantage if you can control and understand what is creating the character of the tone. To approach this vast jungle of variables that controls the tone in a guitar, I built two guitars and in one, guitar 2, reduced the thickness of soundboard, back and sides.The purpose was to compare the guitars and establish if there was a significant difference and what it was, in the guitars ability to produce sound. The thought was also to try the thesis: loud but short, long but moderate tone. Also if a lighter built guitar has an advantage in producing a loud but short ton and vice versa.The instruments has been examined by five guitarist, one guitarbuilder and a professor in Speech, music and hearing at KTH in Stockholm.The relative obvious conclusion is that guitar 2 is a bit louder and has a clearer base and treble but the more part of the guitarists fancied guitar 1 better. This one has got more mass fore the tone to stay alive with.

Background: Sleeping is a condition that is necessary for all people because the body isgiven time to recover. Studies have shown that patients found it difficult to sleep during thehospital stay and it turned out to be several factors that disturbed the sleep during the night.The nurse should note the patient?s need for sleep and take into account environmental andother sleep disturbances to be able to implement nursing interventions. Purpose: The purposeof this study was to elucidate the factors that interfere with patient?s sleep duringhospitalization and nursing care to promote the patient?s ability to sleep.

The acoustics in a control room is a complicated phenomenon. Early reflections, reverberation time and area in the room are some of the problems. This report is about the reflection on the mixing console in a control room. The control room being built, these reflections are difficult to take into consideration since the mixing console is one of the very last items you place in the room. This report will explain three main measurements that were done in order to get the answer to the following question: Does the mixing console interfere the frequency curve at listening position? Three measurements were done and the difference between the measurements was that the microphone and the loudspeakers were placed in different places in the control room.

My objective for this project was to create a short but thrilling 2D-animation intended as promotion for an online comic book. The purpose of the project was to learn more about animation and graphics, to further my artistic skills and to learn how to work in Adobe After Effects. I also wanted to learn more about scheduling, project methods and how to handle stress. During the ten weeks of the project I have created the story, the storyboard, the character design, the backgrounds and the animation. The voice over was recorded with the help of a fellow student who also made the music and the sound effects.
