Semantic Web technology has attracted much interest for its ability to integrate and deliver information from different sources, and increasingly, geodata are being published as triple data according to the graph structure laid out in the Resource Description Framework (RDF). Although the Semantic Web already contains a large volume of geotagged information, there is still a lack of suitable geome

The world as we know it today has evolved to be a very connected space, where not only ICT’s (information & communication technologies) have made it easy to interact with individuals around the globe at any time, but also developments in air travel allow to reach ever more distant destinations. Many go as far as describing the world as shrinking or small; it seems that at least it feels smalle

In recent decades, industrialized economies have significantly increased their R&D efforts while economic growth rates have been relatively stable. This goes against the conclusions of most previous economic models of endogenous growth. In this paper, an endogenous growth model has been created in which technology is treated as an income-compensated factor of production. The purpose is to crea

Denna uppsats undersöker hur den svenska barnrättsorganisationen Bris skapar förtroende och visar försiktighet i sina livechattar, som riktar sig direkt till barn och unga under 18 år. Syftet är att undersöka vilka språkliga strategier som kuratorer på Bris använder i sina svar till barnen för att skapa kontakt och närhet, men samtidigt visa respekt och hålla distans. I undersökningen utgår jag fr

The emerging market for meat substitutes has largely been filled with different types of soy products. Although soy usually has a lower environmental impact than meat, soy is not entirely unproblematic. Deforestation and global transportations are two negative effects of the increasing production of soybeans. One of these meat substitutes is tempeh: an Indonesian mold-fermented food usually made o

With a growing trend of electrification of vehicles there is a need for more flexible and advantageous charging options that reduce EV limitations. To overcome these limitations,dynamic charge through Electric Road Systems (ERS) is in development, and fast charging stations are being deployed all over the world. This thesis focuses on combining the use of both technologies, attempting to use an EL

Det har länge funnits ett fokus på att uppnå en säker och trivsam arbetsmiljö. Den fysiska arbetsmiljön har i över 100 år haft arbetslagstiftning och tillsyn för att skydda de anställda på svenska företag. Det var först år 2001 som regeringen gjorde en sammanslagning av Arbetarskyddsstyrelsen och Yrkesinspektionen som skapade Arbetsmiljöverket. Samma år beslutades det om en stor satsning på den ps

En diofantisk ekvation är en polynomekvation i två eller flera variabler, där polynomet har heltalskoefficienter och man söker heltalslösningar. Det enklaste (och kanske mest praktiskt användbara) fallet är det linjära, ax+by=c. I sådant fall är det enkelt att hitta lösningar (x,y), eller visa att inga lösningar existerar, med hjälp av Euklides algoritm eller kedjebråk. För diofantiska ekvationer This thesis deals with some special types of Diophantine equations. Two classic cases of Fermat's equation are shown to have no nontrivial integer solutions, using two different approaches. The rest of the thesis deals with some instances of y^2=x^3+k, commonly known as Mordell's equation. In most cases, no integer solutions exist.

In this paper we investigate whether a modern approach to identifying the desirable locations to launder money, the Walker Attractiveness Index, is suitable, and compare its projected results with those revealed by the Panama Papers leak. We find that the model does a poor job at predicting the real-world results, and propose that it be revised. To this we provide some policy recommendations that

Urbanization is a process where rural population move to urban places for better job opportunities and facilities. This is a natural process and more or less unavoidable. But when this process takes place rapidly and at large -scale, the urban cities will undergo various changes that will impact the environment. Rapid and large-scale urbanization is mainly observed in developing countries of Asia

In 2013 Kenya implemented their devolution, which is the process of devolving political functions, fiscal resources and administrative responsibilities to sub-national units. The central reason behind this constitutional change was to address the chronic ethnic conflicts of Kenya. A part of the ethnic conflict in Kenya is the plague of corruption, where it has divided the people of Kenya, putting

The purpose of this study has been to look at four peoples life stories about their experiences of drug use over time as well as to share their individual attitudes, and possible experiences, of drug-related support and treatment. The life stories of these four people were collected through semi structured interviews, after which they were analyzed based on narrative aspects conveyed in their stor

In this thesis we test the performance of hedge funds against several fund specific variables, mainly fund size. As a measure of the hedge funds performance we employ both excess and risk-adjusted returns. The first part the thesis employs unbalanced panel regressions where hedge funds excess returns are run on several fund specific variables. In the second part several financial performance measu

This bachelor degree project started out with the question of how future transportation is going to look like and what steps we need to take to ensure that the combustion engine will be in the past. The changes we need to do is evident; electric vehicles are a fast-moving industry, and a global adoption is just a few years ahead. The biggest holdback for accepting electric vehicles is battery capa

The dissertation examines the underpricing of sponsor-backed (private equity backed and venture capital backed) and non-sponsor backed initial public offerings (IPOs) listed on all US stock exchanges between January 1997 and December 2017. The authors identify 403 PE-backed IPOs, 179 VC-backed IPOs and 1469 non-sponsor (non-PE and non-VC) backed IPOs. Evidence suggests that PE-backed firms are lar

At the time for the starting point of this master thesis, the Electrolux Healthy Home department where at a high extent looking into how a system of products that could communicate with one another could give the user a better experience in the home. Products that where looked into for coupling where for example an air purifier with a robotic vacuum-cleaner, maybe also coupled with any other

This paper examines which asset classes that has given the highest risk-adjusted returns during the period of 1914-2013, with a focus on financial crises. The portfolios have been produced by calculation and optimization of the Sharpe ratio as a measure of risk-adjusted returns. The analysis included Sweden, the U.S and Japan and consisted of 9 different asset classes: global stocks, domestic stoc

När vi letar efter exoplaneter finns det ett antal olika metoder för att hitta dem. Den mest framgångsrika är transitmetoden där ljusstyrkan hos en stjärna studeras under en längre tid. När en planet passerar mellan sin stjärna och en observatör kan en minsking i stjärnans ljusstyrka ses. Uppreras detta i regelbunda intervall kan slutsatsen att det finns en planet runt stjärnan dras. Genom att stuA transit is a phenomenon where a planet passes between its host star and an observer blocking out part of the light from the star. This decrease can be measured and used to gain information about the planet. The Kepler and TESS telescopes are examples of space telescopes using the transit method to detect exoplanets. For systems with more than one planet around the same star variations between th

This project was based on a thesis about how product semiotics and aesthetics has defined a design standard for many products. Hence the development for those products may have stagnated. The proj- ect began by researching different products and domains to see how designers throughout the years had “thought outside the box”, to then try to see how much I could push towards that direction. The fi
