Videospelsbranschen växer ständigt och globalt omsätter den idag flera hundra miljarder kronor. Bakom varje enskild speltitel ligger omfattande investeringar av både tid och kapital. Upphovsrätten är den immaterialrätt som ger skydd åt videospel. Att spelutvecklarna kan erbjudas ett effektivt skydd är essentiellt för branschens fortsatta utveckling. Omfattningen av, och formerna för, det upphovsrä
Suveränitetsprincipen fastställer att varje stat fritt får råda över sina interna angelägenheter, utan inblandning från andra stater. Det internationella samfundet har också enats kring att människor ska skyddas från kränkningar av mänskliga rättigheter. Humanitära katastrofer som sker inom en stats gränser belyser en konflikt mellan dessa två fundament inom folkrätten. Utomstående stater ställs iThe principle of sovereignty implies that every state has the right to control its internal affairs, without interference from other states. The international community has also agreed that people should be protected from human rights violations. Mass atrocities that occur within the borders of a state highlights a conflict between these two cornerstones of international law. External states are f
Denna uppsats handlar om skatterättslig hemvist för juridiska personer. Sådan hemvist är avgörande för att bestämma hur en person ska beskattas i ett visst land. I Sverige tillämpar vi registrering av bolag som enda hemvistbegrepp. Detta är vi nästan helt unika med. Ett betydligt vanligare hemvistbegrepp länder tillämpar är verklig ledning, eller ”place of Effective Management”. Detta är dessutom This paper concerns fiscal residence for persons other than natural persons. Such person’s residence needs to be decided in order to determine how it should be properly taxed. Sweden uses registration for corporations as the sole residence concept. This makes us almost completely unique. A vastly more common concept among other countries is “place of Effective Management”. This concept was also us
Plaster som används för dagligt bruk består till stor del av fossila ämnen. Med ökad efterfrågan och produktion för varje år, är en hållbar utveckling för plaster en växande utmaning. Ett av de stora problemen är förbrukningen av de icke förnyelsebara fossila källorna, vilket medför att förr eller senare behövs alternativ till de konventionella plasterna. Med detta problem i åtanke, så fokuserar dPlastics for everyday use are made from fossile resources. With the demand for plastics increasing every year, a sustainable development for plastic products is a growing challenge. A major issue is the depletion of the non-renewable fossile resources, which means that sooner or later alternatives to the conventional plastics are needed. With this problem in mind, this work focuses on the developm
As interest in social vulnerability to hazards grows, more indices are formulated for identifying and mapping population groups that may experience differential consequences from natural hazards. However, less attention has been given to the underlying choices researchers make when creating these indices. With the aim to contribute to understanding the issues surrounding social vulnerability indic
Nowadays, many evacuation models exist in the market, and new models are continuously released with new features. How to assess the usability and reliability of model results becomes an issue for both developers and users. Therefore, verification and validation (V&V) protocols were introduced in the assessment process of evacuation models. To conduct V&V of a model, a widely accepted test
Connecting science to political agenda-setting is essential for a sustainable transition and acceptable politics. This task is complicated by phenomena like post-truth, for which facts are a non-issue. However, post-truth is not the only issue. The practice of political spin, in which the significance of facts is reconstructed according to specific interests poses another threat to scientific cred
In the construction of high-speed railways, an important starting point is to make as little Intrusion on land as possible, therefore it is of high importance to carefully investigate which construction alternatives are the most advantageous. The purpose of this work is to compare and evaluate land use and building on viaduct. The work will be based on literature and interview studies. Sections of
In the later Middle Ages there was a vivid activity of preaching at the Abbey of Vadstena. Apart from the ordinary Sunday preaching at High Mass, or in connection to it, there were a number of feasts due to the saints. At heart of the medieval pastoral theology was The Way of Salvation and the conundrum was how to make people understand how to correct their living in order to get into Heaven as qu
Allting är uppbyggt av atomer, inte bara träd, djur eller bläcket i dessa bokstäver, utan även astronomiska objekt så som stjärnor och planeter. Stjärnor är i princip extremt varma och kompakta moln av atomer, som skickar ut ljus i alla riktningar. Astronomer är intresserade av vilken sammansättning av atomer som bygger upp stjärnor eftersom detta hjälper dem att förstå hur stjärnor och galaxer biStellar abundances are important for understanding the chemical evolution of galaxies and provide us with constraints on stellar evolution and supernova nucleosynthesis. To determine stellar abundances accurately, atomic data is crucial. This data is incomplete for many elements, especially in the infrared region. In particular, hyperfine structure (hfs) data in the near-infrared region is lacking
Previous studies clarified that the electron enriched NADH and NADPH by RBC glycolysis could be used in an extracellular chemical reaction, where electron energies are extracted by an electron mediator methylene blue (MB). The reduced form of MB permeates the phospholipid bilayer of liposomes and reduce encapsulated ferric methemoglobin (metHb) to ferrous hemoglobin. Moreover, in vitro screening s
This master thesis project has been performed in cooperation with TAC, a building automation company in Malmö and the Department of Automatic Control at LTH. TAC has experienced problems for some time with their PID controllers. This master thesis has therefore investigated the use of PID control at TAC, the problems with the existing controllers. The thesis also describes a new PID controller tha
Allteftersom företag har börjat att ompröva sättet de designar, tillverkar och avyttrar produkter inom ramarna för hållbar utveckling så har tillverkare av akustiska produkter varit långsamma ur startblocken. Majoriteten av akustiska produkter är fortfarande primärt sammansatta av nyråvara från petrokemiska resurser, vilka har en signifikant påverkan på miljön. Det är problematiskt ur både en miljAs industries have begun to rethink the way they design, make and dispose of products for the purpose of sustainable development, manufacturers of acoustic products have been slow off the mark. The majority of acoustic products are still made of primarily virgin material made from petrochemical resources, which have a significant impact on the environment. This is problematic from an environmental

Obtaining DNA sequences is a time-consuming task, which typically requires one or several days for completion. One way of reducing analysis times is to be satisfied with long-range sequence patterns on the order of thousands of base pairs. DNA barcoding is a DNA-characterising technique that works according to this principle. It does so by using fluorescence microscopy to visualise long-range sequ
In this thesis a framework for finding anomalies in streaming data is proposed. The framework proposed is not necessarily applicable only to problems in anomaly detection, but could be applied to other problems as well. There are three main concepts at play in the framework: (i) Active Learning, a learning algorithm which can query a human specialist for labels of instance such that the model can
Sent i oktober 2012 så orsakade orkanen Sandy stor skada på de Karibiska öarna men senare även i USA, New Jersey, då som ett extratropiskt system. Vädersystemet var annorlunda på många vis jämfört med en "normal" orkan med avseende på dess bana, avsaknaden av ett öga och dess enorma storlek. Dessa egenskaper berodde alla på den rådande cirkulationen i den övre troposfären. Det var växelvIn late October 2012 hurricane Sandy caused a lot of damage to the islands in the Caribbean Sea and later on (as an extratropical cyclone) to the United States; New Jersey. The system was different in many ways relative to “normal” hurricanes, e.g. its track, its lack of eye at times it was classified as a hurricane and its great size which all partly was due to the prevailing circulations in the
Popular science Climate change impacts on water balance of the Mediterranean region Some regions and ecosystems are more sensitive than others in the face of a climate change. Mediterranean region which is the problematic of this thesis is one of those regions. Even now regions is showing differences on its hydrological pattern because of temperature rise.

It is essential to model the water balance of this region in order to better understand the impacts of climate change. The water balance expresses the net result of the flow of water from atmosphere to the surface and vice versa. It is one of the
