I denna uppsats kommer vi dokumentera vidareutvecklingen av Softwerk AB?s Content Management System kallat AppCMS. I dagsläget innefattar AppCMS plattformarna iOS, Android och Windows Phone. Kunderna till Softwerk AB har dock uttryckt ett behov av att även kunna nå ut till sina användare med en webbaserad samt en utskrivningsbar lösning. AppCMS?s exportformat har därför analyserats för att undersöka möjligheten till att återanvända det existerande exportformatet från AppCMS  även för dessa plattformarna.

Context. Performance and resource usage is often an important factor for database driven services. Depending on the purpose of the application, choosing the wrong type of database may require unnecessary hardware upgrades or replacements. Objectives. This study investigates the differences in performance and resource usage between different SQL- and NoSQL-databases. The study is a comparison that focuses on how the databases perform in different applications.

This master thesis work was done at Saab Underwater Systems AB, a company at the cutting edge of underwater technology. Here torpedoes and other underwater vehicles are developed and manufactured. The major customers are navies of different countries, mostly the Swedish navy. The aim of this master thesis is to develop, construct and evaluate an automatic Trim System for Unmanned Underwater Vehicles. The task of the system is to change the position of the centre of mass and the vehicle?s total mass or volume.

The paper discusses the problems contemporary Swedish art criticism faces when judging performance art and interactive art. Problems include among others that performance art is collectively ignored in Swedish newspaper art criticism. This prevents art critics from fair contextualising of contemporary performance art. Down in the rabbit hole, performance by Tris Vonna-Michell and its reception exemplifies these problems. Performance and interactive art seems to be disturbing art critics.

Under de senaste åren har webbplatser blivit allt mer komplexa och informationen som ska visas och hanteras allt större. För att underlätta hantering och administration av dessa system har många CMS-system vuxit fram. Dessa system kan skilja sig mycket beträffande pris och funktionalitet, allt från mindre open source system till stora komplexa kommersiellt drivna system. Detta arbete bygger på att skräddarsy ett CMS-system för administration och hantering av innehåll på diverse artist sidor, som hanteras av ett medieföretag. Systemet använder tekniker som JavaScript, PHP, MySQL som grund för dess uppbyggnad.

Många lärosäten använder idag fler än en lärplattform, ibland inom en och samma institution, program eller kurs. Uppsatsens syfte var därför att ta fram riktlinjer för vad som bör beaktas vid val av lärplattform för att fylla organisationens behov och passa dess förutsättningar. Undersökningen genomfördes med en kvalitativ datainsamlingsmetod där vi genom intervjuer med fem lärare vid Linnéuniversitetet samlade in deras krav. Resultatet blev en checklista som listar lärarnas krav och genom att kritiskt granskat litteratur kan vi rekommendera organisationer vad de bör överväga inför implementationen av en lärplattform..

Konsultverksamheter har idag en stor mängd system och leverantörer att välja mellan vid val av att bli återförsäljare till ett nytt system. Denna mängd av system kan vid vissa tillfällen ställa till osäkerhet i form av vilket system som passar bäst in i verksamhetens portfolio. Genom en effektiv utvärdering kan dock detta avhjälpas och det system som passar bäst för verksamhet väljas. Uppsatsen bygger på en kvalitativ litteraturstudie där också en intervju utförts. Vidare har de teoretiska utgångspunkterna hämtats utifrån modeller såsom Standardsystem i Verksamheter och Välja och Förvalta Standardsystem. Dessa modeller ligger sedermera till grund för den modell som presenteras i uppsatsen och förenklar konsultverksamheternas problematik med att fatta ett genomarbetat val av system till sin portfolio..

This thesis concerns waste management on construction sites and was conducted on behalf of ICA Fastigheter.Areas of concern:How can an environmentally-efficient waste management system on construction sites be defined? What potential exists for exploiting the waste resources that are generated?How can the waste management be optimised by reducing the quantity of waste and by optimal sorting?How can the client of a project influence the waste management?The purpose of the work was to investigate sustainable waste management in the building and construction sector and to highlight waste as a resource from an environmental and economic perspective.The aim of the work was to define an environmentally-efficient waste management system, to analyse the potential that exists in waste management and to draw up guidelines for optimal waste management.The method consisted of a literature study, two visits to construction sites and four interviews.An environmentally-efficient waste management system means that the waste is managed in the following order of priority:Prevention     Reuse  Recycling     Energy recoveryLandfill     The prevention of waste is an important area that has not been adequately explored by the building and construction industry. The quantities of waste could decrease with the implementation of measures such as ordering materials in the dimensions required, prefabricated components, logistics centres with Just-In-Time deliveries, less and improved packaging and less wrapping. The reuse of waste materials and temporary apparatus as well as the use of a return pallet system are examples of reuse that reduces the quantities of waste.In most cases the source sorting work is a matter of course and the proportion going to landfill is down at a low level. The source sorting can be optimised by sorting all materials that can be reused and recycled to use them as a resource.

The purpose with this essay is to examine how arts and politics integrate to raise urgent messages and call upon social changes. Performance art as an artistic manifestation against the surveillance society has been studied to clarify this integration and through an empirical examination of the anarchistic performance group The Surveillance Camera Players. This group formed in New York City 1996 as a manifestation against the increased use of surveillance cameras in public places in Manhattan. Through performance in front of these cameras, The Surveillance Camera Players are able to express their protest against the surveillance society which, occurring to them, violates citizens constitutionally right to privacy. The development and signification of the surveillance society are examined through theoretical perspective by foremost Michel Foucault, but also by contemporary scientist in that field.

This thesis examines underpricing and the long run performance of IPO firms on the Swedish equity market during 1994-2010. We further investigate whether any correlation exist between underpricing and post-IPO performance during 36 months. We use a sample of 80 IPO firms. To examine the aftermarket performance we compare total return of each firm with a matching industry index. In order to strengthen our analysis, we run a second test, comparing actual return for each firm with expected return, adjusted for firm specific risk.

The climate issue is a significant question, and the problem is mainly caused by human activities. Everyone can help to counteract the enhanced Greenhouse effect by reducing the amounts of energy they use and by not consuming more products then they need.Schools are some of societies many consumers and therefore contribute to the Greenhouse effect. The School also has an important task; to teach and disseminate knowledge and information about the climate and the environment. According to the Swedish National Agency for Education, Skolverket, must all schools regularly consider the environment and sustainable development throughout the entire education process. Unfortunately, this is not the case for many schools in Sweden today.One of many tools that can be used to coordinate environmental work and initiatives, and also to make it more efficient, is environmental management systems.

Försvarets materielverk (FMV) står inför en omfattande ominriktning av verksamheten med tillhörande omorganisation. Den nya verksamheten innefattar att leverera tjänsten försvarslogistik till Försvarsmakten (FM). Då det inte finns någon entydig definition för vad försvarslogistik är så har detta arbete inriktats att utarbeta ett förslag till en sådan definition. Dessutom har en procedur skapats som identifierar relevanta prestandamått för ett godtyckligt försvarslogistiskt system, s.k. Key Performance Indicators (KPI), som kan användas för att påvisa om försvarslogistiken är effektiv eller inte.

The main purpose of this Master Thesis has been to evaluate whether active fund management is profitable on Emerging Markets. The material used to examine this consists of 106 actively managed funds, with varying length during the period 1988-2006 and who uses MSCI Emerging Markets (MSCI EM) as benchmark index. The thesis has been written under the supervision of the Asset Management Department of Länsförsäkringar AB (LFAB) and the Department of Production Economics, Linköping Institute of Technology. Apart from the main purpose, the methodology used is also meant to form a template for in-depth or similar studies, preferably by the assigner of this survey, LFAB.The results shows that the median manager underperforms the MSCI EM throughout the whole period, which leads to the conclusion is that active management on Emerging Markets is not profitable. A grouping of the funds based on tracking error still shows that a majority of the managers in all of the groups underperforms against the benchmark.

The purpose of this thesis is to examine how the Management Control System is affected by a change in the owner structure from family owned to not-family owned. The study also tries to identify explaining factors behind the possible effects to the Management Control System. The study is based on a comprehensive case study on the company Alcro-Beckers which, in year 2001, was acquired from the owner Lindéngruppen fully owned by Ulf G Lindén. The acquirer was the non-family owned company Kemira OY, a Finnish stock listed group. The empirical foundation mainly comes from interviews conducted with people who were/are directly connected to the company, either as employees or as representatives for the owner.

This thesis compares the impact on disk performance in a GNU/Linux  environmentwith three encryption algorithms: AES,  Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that  is  drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..
