När tippen blir toppen -En studie om soptippars omvandling : Hur blir de en tillgång och för vem?
A high degree of urbanization with growing cities has raised a need of transforming closed landfill sites for giving them new uses. This study aims to investigate how old landfills can be re-used, what has lead to the new uses, and for what and whom the transformed site will be an asset. The method used is a case study of four different landfills in Stockholm county, Sweden. The case study is analyzed in the light of former studies regarding re-use of degraded urban areas, so called brownfields, and in particular studies and reports of landfill re-use. The result indicates that old landfill sites is identified as an area with possible values if transformed properly, in the case study area especially as green structure and recreation areas.
Konstruktionsforslag for kabelprovningsutrustning av serieresonanstyp
In order to decrease the disturbance from a cable testing equipment, the company Ericsson Network Technologies in Falun determined to design a new series resonant test system with a lower frequency. The new equipment is of series resonant type with a system frequency of 500 Hz. This equipment consists of an inductor, a capacitor and a voltage source. The voltage source is the same as the old one, the cable acts as the capacitor but the inductor has to be designed especially for the new equipment. In this thesis work several air coil inductor types were examined.
Webb-tv ? en konkurrent eller ett komplement till linjär tv? : En studie av hur SVT och TV4 ser på sin webb-tv
The linear televison have dominated the supply of moving pictures, but this is about to change with the possibility to consume it via the Internet.I n this thesis we have studied how the two Swedish tv-network companies, SVT and TV4 are working with their web TV and if their online services have affected the linear TV. To limit the size of the study we chose two network companies that provide the most popular tv channels and web services in Sweden. To gather data from these two companies we conducted qualitative interviews with people at the networks. We came to the conclusion that SVT and TV4 doesn't find that their web TV services (called SVT Play and TV4 Play) are competing with the linear TV. They rather regard them as assets to broaden their services.
Metod för dosoptimering av digitalt detektorsystem i klinisk drift
The county of Dalarna is at present carrying through a process of digitalization where traditional x-ray film is being replaced with digital detectors. Earlier used methods for dose optimization turned out not being sufficient. This report presents a method to harmonize dose levels between x- ray sites equipped with Fujifilm imaging plate systems. An exposure index, S, related to the dose level of the examination is computed to every x-ray image. S turned out to be inversely proportional to the detector dose used at the examination.
Lek hos Stinkpadda (Bufo callamita): jämförelse av restaurerade och ickerestaurerade hällkar
The natterjack toad (Bufo calamita) is one of three species of toads living in Sweden. During the last decades declines in population numbers have been detected and are thought to be primarily due to loss of habitat, overgrown breeding ponds and competition from common toad (Bufo bufo) and common frog (Rana temporaria). In 2012 20 ponds in the location of Glommeskallen in Smögen were restored by clearing the ponds from overgrowth. The aim of this study was to investigate if natterjack toads used the restored ponds and if the restoration had made an impact on the natterjack population on the location. Presence of common toad and common frog was recorded, as was the presence of eggs and larvae of any of the three species.
Textilhantverkets betydelse i Uppåkra - en studie av Uppåkra och närliggande agrarboplatser
This survey deals with textile production and how it was carried out during the late Iron Age,with main focus on a central place, Uppåkra. A comparison has been carried out betweenUppåkra and two agrarian settlements, Fosie and V. Karaby, from the nearby landscape toinvestigate whether any variation in production can be detected. The value of textiles has alsobeen investigated to determine whether a potential specialization in production may have ledto a surplus.An analytical and comparative method has been used with focus on the context of thematerial.The results show that the textile production vary at the different sites, and that a need fordifferent types of textiles has existed. At Uppåkra, the possibility to produce fine threads andtextiles existed as demonstated by the findings of small and lightweighted spindle whorls.This suggests that the production may have included both fine and coarse textiles.

Analys av systemfaktorers påverkan på tillförlitligheten i distributionsnät
In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.
DNS prestanda
Use of computers and computer networks is nowadays a part of everyday life. You do not use them only at home when you sit at you computer, but you can use them all the time everywhere. This can involve everything from surf to any website when you are at home, to checking your email on your mobile when you are on your way to work. Most people do not think about how it really works when they try to access a web page by typing the address into their browser, but something that most people probably notice is how long it can sometimes take to access a web page.All items which are directly connected to the IP network have a unique IP address that is used to make it possible to communicate. The IP address is either a period separated sequence of digits representing 32 bits or a colon separated sequence of digits representing 128 bits, depending on whether the address is an IPv4 or IPv6 address.

Marknadsföra Innovationer: Hur länken mellan teknologisk innovation och värdeskapande är avgörande för framgång
Near Field Communication, NFC, is a short-range wireless communication technology that enables data exchange between devices in a secure way. A NFC phone has the potential to enable the convergence of wallet, phone and keys, but as many other technological innovations, the launch is struggling. We have discovered that technological innovation is only the first step. For an innovation to be adapted, there need to be business model innovation too. Many actors form the ecosystem of NFC and the business model for each service is still an unsolved problem.
Spelar representativ demokrati någon roll? : En fallstudie av nätverket Leader Linné
It has become popular for political scientists to discuss the transformation from government to governance and the networks? greater influence on public policymaking. However, this debate lacks methodological, empirical and theoretical research about the relationship between governance networks and representative democracy. The main objective of this essay is to understand the relationship between governance networks and representative democracy through a case study of the governance network Leader Linné. The theoretical framework includes four analysis models about the relationship between governance networks and representative democracy that are analysed by five factors connected to representative democracy.
Karlshamn-Wislanda Jernväg : Maktelit och nätverk i Karlshamns stad vid banans tillblivelse 1855-1874
The aim of this essay was to describe the power elite of the Swedish town Karlshamn, and its influences on the local political process before the realization of the narrow-gauge railway Karlshamn-Wislanda-Jernväg. During the mid 19th century, a revolutionary period began in the Swedish pre-industrial epoch. The political and institutional regulatory frameworks were disassembled and restructured, away from protectionism and centrally controlled administration, for the benefit of free trade, local self-government and liberalism. The changes were carried through during times marked by a drastic increasing native population and upcoming demands for adjustments to meet the growth of the industrial-, trade- and labour markets. An essential industrial development factor was the building of the national railway network, which started after some important decisions in the Swedish Riksdag during the 1850´s.
I jakt på tillämpning : Om F.O.V. Fabrics möjligheter att understödja kommersialiseringen av algbatteriforskning
The purpose of this essay is to explore the actor network of a high technology company in the textile industry called F.O.V. Fabrics. The background for doing this is a recent project, which we choose to call the Salt & Paper Battery Group, aiming to commercialize a newly discovered technology ? a battery based on cellulose from an alga. We start by examining a range of network theories in order to eventually shape a framework of our own.
Digital Storytelling
The purpose of this paper is to analyze and map out the cyber culture of the Internet and its all users, identity, design theories and services. How people communicate and how they build up their identities are some of the baselines. I will also discuss the important aspects of Interaction design and how this can be used in a Community for digital storytelling.
The Internet, or new media, was founded in the 60?s by some great philosophers (McLuhan, Rheingold, Lambert and more). With influence from their books I will discuss and analyze what kind of media the Internet is and how it can be seen as extensions to our senses, as McLuhan claims.
