Rum för musik på biblioteket: En fallstudie av Bibliotek 10 i Helsingfors
The aim of this master's thesis is to study how the design of the music library space affects how it is used and its role as an arena for culture. This is done in form of a case study of Library 10 in Helsinki, a public library branch that specializes in music and information technology. The backdrop to the study is the changing context for cultural activity in the information society and the role of public libraries as public space and meeting place. By analyzing the distribution of space in the library, the distribution of functions and artefacts and the spatial use of the room, I interpret the ways in which this distributional logic produces a unique place for music and culture. I discuss the music library design in a space and place perspective, utilizing theoretical tools from cultural geography and the space theories of Henri Lefebvre.
Spårvagnstrafik i Västerås? : En förstudie i förutsättningarna för modern spårvagnstrafik
Läns- och lokaltrafikens branschorganisation Svensk Kollektivtrafik har som mål att år 2020 ha fördubblat kollektivtrafikresandet från 2006 års siffror. En sådan förändring kommer inte att ske av sig självt utan ett målmedvetet arbete kommer att krävas för att göra kollektivtrafiken mer attraktiv. En alltmer aktuell utveckling av kollektivtrafiken är att flera svenska städer har mer eller mindre långtgångna planer på att införa spårvagnstrafik. Detta examensarbetes syfte är att utreda förutsättningarna för en spårvägsetablering i Västerås Stad. Arbetet delas in i litteraturstudie, fallstudie, enkätstudie samt intervjustudie.

Applikationsintegrering : en analys av metoder och teknik
Abstract In the contemporary world of information technology you find a multitude of applications and systems covering a broad spectrum of areas of need in different companies. One effect of this multitude of programs is the difficulty to make them exchange information with each other or to collaborate, since they are developed by different programming languages for different platforms, with different standards and different data formats. Our aim with this work is to describe how it is possible to tie these programs together to make them actually communicate with each other in order to exchange information, share their native methods and also to become a part of the overall business processes. In this integration task you will, among other things, find different levels of application integration such as data level, method level, application interface level and user interface level integration. Application integration also involves hardware components, called middleware, that facilitate the physical connection between applications.
Analys av framtidens system för hantering av avloppsvatten och matavfall i Eskilstuna
Wastewater treatment is increasingly controlled by the Swedish environmental quality objectives, adopted by the Swedish parliament. There is a need for a sewage system that can fulfill stringent requirements concerning the environment, recycling and resource use and hygiene. Additional environmental aspects in recent years are the impact of climate change, new knowledge about the effects of pharmaceuticals in water, the need for improved wastewater treatment and increased recycling of nutrients to agriculture. This report has, from a future scenario of the year 2050, analyzed seven different systems for wastewater treatment and treatment of compostable biowaste from households in Eskilstuna. A future scenario was chosen based on that within a forty year period new challenges may arise which can result in higher demands on sewage treatment than those we see today. Another reason why the future scenario was established is that changes in wastewater treatment systems are slow to establish. The analysis is mainly focused on the economical aspects but environmental aspects such as emissions to receiving waters and potential recycling of plant nutrients has also been evaluated briefly.
Skolan i universum - att förklara det ofattbara : Astronomiundervisningen i skolan på 1900-talet
This is a study in how astronomy has been taught and is being taught in Swedish schools from 1905 to this date with an emphasis on the latest 30 years. It concerns the regulations and methodical recommendations/curricula for Swedish junior high school/Swedish Comprehensive school for the years 1905, 1933, 1955, 1958, 1962, 1969, 1980 and 1994. The matter of integrating astronomy with other subjects and different methodical approaches is also considered. The problem with textbooks written only for one subject when the teacher tries to integrate subjects is emphasised.Physics textbook analysis shows that astronomy teaching has over the years developed, from being based on observations, to become more and more theoretical. It also shows that the amount of practical exercises has been fairly constant in physics textbooks during the seventies end eighties but now in the nineties varies a lot from textbook to textbook. The amount of liberty the textbook gives the pupil in finding knowledge and answers himself in the practical parts of astronomy was at its lowest during the seventies.
The Low Line : ett gestaltningsförslag med inspiration från The High Line
In the summer of 2009 the High Line opened in New York, a park built on an out-of use elevated rail viaduct. The park meanders its way through the buildings and allows the visitor to see the city from a totally different perspecive than we are used to.I have made a Design proposal in Eriksdalslunden, Stockholm, with inspiration from the High Line. The proposal is based on design ideas of a park I logically call the Low Line, as the place isn't elevated as in New York, but lowered. The two places have some similarities, mainly the strong urban identity and the tracks crossing both areas. They also have very obvious differences, above all the fact that Eriksdalslunden is situated in a swale and is defined in a third dimension by the high bridges that crosses the area.The High Line is designed by James Corner Field Operations, and they have been working using their motto 'Keep it Simple, Keep it Wild, Keep it Quiet and Keep it Slow' during the whole process, words that normally aren't associated to Manhattan.
Relevans och svårigheter i användandet av vardagsteknik i dagliga aktiviteter hos yngre vuxna
Vi lever i ett informations- och teknologisamhälle och i våra dagliga aktiviteter omges vi av vardagsteknik (VT) på olika sätt och i olika svårighetsgrad. Denna VT kan innefatta allt från brödrost till mer avancerade datasystem och tjänster. Tidigare studier visar att personer med kognitiv funktionsnedsättning kan uppleva svårigheter i användandet av VT i sina dagliga aktiviteter. Dock finns inga studier som visar relevans och svårigheter med VT för yngre vuxna utan kognitiv funktionsnedsättning. Därför vill vi med den här studien beskriva relevans och svårigheter i användandet av VT hos yngre vuxna utan kända kognitiva funktionsnedsättningar.
En IT-forensikers kamp mot IT-brottsligheten : En studie om arbetssätt hos polisens IT-forensiker
The use of information technology (IT) is exploding. Today, it is in our daily routines to use some kind of information technology. The increase of users increases the number of cyber crimes, ie, crimes that in some way involve IT. As the cyber crimes grow in numbers, the workload for technical investigator increases, these are called digital crime investigators. The thesis is about how police digital crime investigators work and what problems they may encounter during an investigation.

Lärare, digitalteknik och motivation : En studie om vilka aspekter som påverkar lärares motivation att använda digitalteknik i undervisningen
Studiens syfte är att utveckla kunskap om lärares motivation till användning av digitalteknik i undervisningen. Ämnet belyses genom frågeställningarna; Vilken förståelse har lärare för den digitala teknikens roll i undervisningen? och Vilka aspekter påverkar lärarnas motivation till användning av digitalteknik i undervisningen? I studien deltar fem verksamma lärare som undervisar i årskurs 1-6. Utifrån semistrukturerade kvalitativa intervjuer beskrivs och kategoriseras aspekter som påverkar lärarnas motivation till att använda digitalteknik i undervisningen. Studien visar att tvetydighet präglar lärarnas förståelse för den digitala tekniken. Lärarna uppvisar en förståelse för teknikens möjligheter och utnyttjar den för personlig utveckling och som informationsbank.Det framkommer dock inte lika frekvent att den digitala tekniken används i undervisningssituationen. Det är flera aspekter som påverkar lärarnas drivkraft att använda digitalteknik i undervisningen.
Marknadsanalys av ett svenskt transportsystem med höghastighetsgodståg.
In Sweden plans to build high speed railways have been around since the early 1990s and the planshave developed to be more precised since. The future Swedish high-speed rail network is supposedto consist of two lines. Götalandsbanan; from Stockholm to Gothenburg, and Europabanan fromJönköping through the Öresund Region to Hamburg.The description of the aim to build high-speed railways in Sweden has in former reports always beento achieve rapid passenger traffic between big Scandinavian cities and Europe. There are almostnothing mentioned about the possibilities of high-speed transports of cargo on these railways. Thisstudy aims to clarify the freight transport market for Götalandsbanan and Europabanan.Today there is only one transport system with high-speed freight trains.
Miljöarbete inom den civila luftfarten
The main environmental problem for aviation is the great amount of exhaust gases, mainly nitrogen oxides, carbon monoxide, carbon dioxide and hydrocarbons - mostly "greenhouse gases" leading to climate changes. I decided to sort out what is being done to decrease these problems and what regulations there are concerning air pollution by the means of searching the internet and using publications from aviation authorities for current figures. I chose to scrutinize authorities on political, authority and company level, resulting in summarizing the work of UN and EU respectively, ICAO (International Civil Aviation Organization), JAA (Joint Aviation Authorities) and LFV (Swedish Civil Aviation Authority), and finally SAS, representing the airline companies. Conclusion that I have drawn are thatthere are regulations for air pollution, written down in ICAO's Annex 16, that are to be followed. Secondly, LFV are environmentally controlling their nineteen airports and since economy is an important reason for not giving priority to environmental issues in aviation emission charge and noise charge are added to the landing fees.
Könsselektering av spermier från lantbrukets husdjur
Millions of preselected progeny have been born since the development of The Beltsville Sperm Sexing Technology 1986. The method is based on flow cytometry and sorting is done on the basis of DNA difference of the X- and Y-chromosomes. Preselection of progeny provides an opportunity to obtain genetic gain and increased production as well as increased animal welfare and decreased environmental impact. However, the method is associated with low fertility, high costs and uncertainty whether the sorting process contributes to DNA damage and thereby results in genetically impaired progeny. Today, sex sorted sperm is only commercially available in the bovine industry, due to the fact that bull sperm is more suitable for selection than sperm from other species.
Datahantering vid dynamiska webbteknologier : PHP eller ASP?
The last couple of years the use of Internet has changed in the way that the web pages can be affected of the person that uses them. Because of this dynamic Internet technology has emerged that makes it possible for a web page to receive information from a web browser. This information can then be used to affect the appearance of the page. PHP and ASP are two dynamic Internet technologies. They are integrated in HTML and are executed on the web server.
