The amount of information stored on the internet grows daily and naturally the requirements on the systems used to search for and analyse information increases. As a part in meeting the raised requirements this study investigates if it is possible for a automatised text analysis system to distinguish certain groups and categories of words in a text, and more specifically investigate if it is possible to distinguish words with a high information value from words with a low information value. This is important to enable optimizations of systems for global surveillance and information retrieval. The study is carried out using word spaces, which are often used in text analysis to model language. The distributional character of certain categories of words is examined by studying the intrinsic dimensionality of the space, locally around different words.

We have performed a case study on Acne Jeans, a creative Swedish fashion company, which initiated a cooperation with the Swedish venture capital firm Öresund. The aim of our paper was to examine what motivates a venture capital firm to transform the management control system of a creative company, into a more formal system of control. Main results: Öresund did not have an excessive impact on the management control system of Acne Jeans, due to three main reasons. First of all, Acne Jeans had a satisfactory management control system prior to the cooperation. Furthermore, the relationship between the two parties was characterized by mutual trust.

As a part of the fight against the global warming the energy production needs to be more efficient and redirected towards sustainable options. One alternative is cogeneration, which means that electricity and heat is produced in one plant. The purpose with this survey is to examine if there are any commercial available combined heat and power techniques, based on combustion of solid moist biomass, which are suitable to small-scale applications. The technique must be able to produce between 2 and 10 MW thermal and the heat demand is a Swedish district-heating system. When already published reports had been studied, the Organic Rankine Cycle (ORC) was chosen as the most suitable technique.

Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

Denna studie jämför hur Capital Asset Pricing Model (CAPM) och Fama-French trefaktorsmodell förklarar och förutspår avkastning på en global aktiemarknad. CAPM utgår ifrån att investerarna förväntar sig en riskfri ränta adderat marknadspremien multiplicerat med företagens exponering mot marknaden. Fama-Frenchs är en utvidgning av CAPM modellen, där företagens storlek och book-to-market-värde läggs till som förklarande variabler för avkastning. Genom regressionsmodeller och prediktioner för portföljer indelade i storlek och book-to-market jämförs modellerna. Fama-French tycks vara genomgående bättre på att förklara och förutspå avkastning under perioden 1990m07-2013m02 för samtliga portföljer, förutom portföljen för stora företag med medelhögt book-to-market värde.

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

In the year 1800, about 5 % of the world population lived in cities (World Wide Fund for Nature, 2012, 3). Today that number is about 70 % in Europe and North America, and in 2050 it is expected to be 86 % in the developed world and 67 % in the developing world (www, UN, 2009). In addition, the global population is expected to increase with 2.2 billion people until 2050. As a result of the population increase more food has to be produced which requires more transport from the countryside to the cities. However, this flow of resources faces some difficulties.

In Stockholm, Johanneshov the Slaughterhouse area (Slakthusområdet) can be found. A number of companies have gathered there providing the Stockholmers with meat products. This area has a great need for cooling to supply large cold storages. To facilitate this, a central cooling system has been built, supplying the area with effective and safe cooling.The aim of this master thesis study is to give hints to energy efficient and reliable changes that can be put in place at a low marginal cost depending on the future activities in the area. The suggested changes will be presented to the company Bravida (managing the system), which also desires a deeper understanding of the energy flows through the central cooling system.Firstly visiting the site with proper guidance, we have then tried to understand the function of the system including which machines and media that are used.

Inbyggda system blir allt vanligare i dagens samhälle. De inbyggda systemen finns i nästan allt nuförtiden, från diverse fordon till leksaker för barn.Dagens teknik innebär bland annat att gårdagens lösningar kan realiseras på en bråkdel av den tidigare ytan. Allt mer blir ytmonterat med mindre och mer komplexa kretsar. Detta är inte alltid till utvecklarnas fördel då montering av prototypkort blir en svår och/eller dyr process.Målet är att ta fram ett inbyggt system med en ARM-processor. Systemet ska innehålla USB-OTG, ethernet, minne av olika slag som FRAM och microSD samt en display med pekskärm för användargränssnitt.

The aim of this study is to examine the possibilities to use gamification to reach thepolitical goals for the transportation system in the Stockholm region. The study has aninterdisciplinary approach and is based around two main building blocks: gamificationand the transportation system in the Stockholm region. The first part examinesgamification. This includes contemporary use, debate, academic definition and aninvestigation of how gamified applications should be developed. One of the mainfindings is a suggestion that gamification should be seen as a process rather that a setof predefined game mechanics that can be applied to any activity.

Obesity is a growing global health problem among both humans and cats with the risk of several medical conditions as a result. This can be detected and prevented by body condition assessment methods in order to visualize and detect possible or potential weight problems in cats.To achieve the best results, owner and cat should be introduced to this as soon as possible in their contact with veterinary care.Purina Body Condition System and Walthams Feline Body Mass Index are both morphometric assessment methods that are quick, relatively cheap and simple to perform. 20 cats with owners and a veterinary nurse student participated in a study to compare pet owners and a veterinary nurse student's assessment of the Purina Body Condition System and WALTHAM's Feline Body Mass Index. The body condition assessment methods were compared with each other, and it was investigated which method was preferred, the body condition distribution among the studied cats and if long-haired cats' body condition was more often misjudged. Results of the study showed a significant difference between pet owners and the veterinary nurse student's assessment of Purina BCS with a difference in median of 1.

The most common method for identifying merchandise in the commerce is by barcodes. Symbian OS is an advanced operating system aimed at cell phones and the most commonly used in smart phones. Opportunities to a full range of new services are given through barcode recognition in a Symbian OS based device. Therefore the purpose of this degree project was to create an application which would contribute to a future solution aimed at shopping where the cell phone constitutes a reader of items? identification numbers.

The purpose of this study was to create a picture of Södra´s round wood transporters usage, and positive or negative experiences of the KOLA-system. The KOLA-system, owned and managed by SDC, is a program for handling timber orders and displaying their locations on digital maps. The study was conducted as a twenty-three question internet-based survey. Of those asked to complete the survey, 57 percent chose to answer the questions. The results of the study indicated that several of the transporters found the system quite good and used it to a large extent. The system also had many deficiencies however, and there was clear potential for further increasing the usage of the system.

The topic of this master thesis in legal science is state law and constitutional law, or more specific judicalization, with the division of power and thus increased individual legal rights in various forms. Sweden has traditionally had a weak constitutional protection for the individual?s legal rights. The public power has been concentrated to the government and the courts have only played a marginal role. Since the implementation of the European convention of legal rights and with the ever-increasing importance of the legal system of the European Union, the Swedish legal system gone through changes of historical dimensions.This master thesis is based on the legal dogmatic method where laws, preparatory work, case law and doctrines have been systemized.

På senare år har debatten om företags sociala ansvar rönt uppmärksamhet både i media och i företagsvärlden. Från omgivningen ställs allt större krav på att företag skall integrera etiska och sociala hänsyn i sin verksamhet och ta ett socialt ansvar för de konsekvenser som företagens verksamhet medför för människa och miljö. I stort handlar det om krav på att införliva även andra värden än monetär lönsamhet och effektivitet i företagsvärlden. Med den ökade makten som globala företag har i världen är det knappast förvånande att också ökat ansvar krävs av dem. Men vad är egentligen socialt ansvar? Hur kan företagen ta ansvar och hur långt bör det ansvaret sträcka sig? Ett ökat ansvarstagande medför ett ökat anseende för företagen och kananvändas för att stärka företagets varumärke.
