Distributionell karaktär hos vissa kategorier av ord
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.
Nätbaserad utbildning för en hållbar besöksnäring
A system to regulate both quality and sustainability regarding Swedish tourism industry is under way. In order for the system to be successfull it needs to be accompanied by an education, in this case a net based education is studied.High requirements are demanded for a successful net based education for a sustainable tourism industry. This is valid both for the didactic area, which is how an education is structured and planned and in the organisational area, which is how and education best is implemented in a company. The aim with this study is to increase the understandings of which aspects that are important for developers if this net based education. The study was conducted at three hostels in Stockholm with surrondings. Both managers and employees participated in the study. The managers where interviewed and got to answer a questionniare.
Hur har EU:S regionalpolitik påverkat Sveriges regionalpolitik?
The purpose of the following essay is to analyze how the Swedish regional policy has been influenced by the regional policy in the EU. The study builds on the theoretical framework that is Europeanization, the top-down approach, which stipulates where you can find evidence of this influence. To obtain the information that I needed to answer my question formulations, which main question formulation are; in which way has the EU regional policy influenced the Swedish regional policy? I used the method of literature analysis. Both the theoretical framework alongside the chosen method pointed me to analyze the public debate in Sweden in the regional question.
Sverige och Art- och Habitatdirektivet - i samförstånd eller avvikande : En studie om reglerande dokuments roll i implementeringsprocessen
Within the political science literature that deals with the implementation process a central part has long been what is sometimes called the implementation deficit. This means that the effect of a policy decision doesn´t turn out as it was originally intended. The often used explanation is that the policy decisions moves through many levels during its implementation where different actors can change or alter the decision in various degrees. This phenomenon has gradually become more and more attended within the legislative process in the European Union and has been addressed in numerous studies. The purpose of this paper is to examine the implementation of The Habitats Directive, as its embodied in regulatory documents, in the Swedish multi-level system.
En analys av centralkylan i Slakthusområdet i Stockholm
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.
ARM i inbyggt system - med prototyp
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.
Hur har handeln med omvärlden påverkat det effektiva utbudet av arbetskraft i Sverige? - faktorinnehålls-analys för år 1995 och 2000
Through trading with countries that have a relative aboundant supply of labor, Sweden changes it's effective supply of labor, in a Factor Content perspective. This essay does two Factor Content analyses, one for year 1995 and one for 2000. The first comparison of these analyses shows that Sweden exports about 27 600 labor-years more year 2000 than 1995. However, since Factor Content analysis arguably underestimates the imported labor, some assumptions are made in order to correct for this. This correction has great importance for the final analysis.
Solenergi och värmelagring i kvarteret Lagern
Humanity stands before a huge challenge to lower its emissions of carbon dioxide and its use of energy at the same time as the global population is rising and the developing countries are being industrialized. A lot of newly built buildings are due to this challenge, designed to be more energy efficient but also use renewable energy resources instead of pollutant fossil fuels .Solar energy is one of the purest forms of energy that exists in abundant amounts, which is why it is most likely that it could come to play a major part in the future energy market. The main purpose of this report is to investigate the possibility to implement a sustainable energy system with solar thermal heat and heat storage as main sources of energy in the neighborhood ?kvarteret Lagern?, which is the area where the old football stadium ?Rasunda Stadion? was located. New developments within different heat storage techniques have opened up new approaches to enable buildings an all year round heat supply from solar energy. This report will focus on heat storage in boreholes. At the present here is only a preliminary plan of how the neighborhood is supposed to be designed.

The study aims toprovide an overview of the mostbeneficial bridge material from bothenvironmental and economic point ofview.The life-cycle analysis covers onlycarbon dioxide emissions, since it isthe most spoken of in today?s climateagenda. Furthermore, this study aims tohighlight which parts, of the systemboundary, that contributes to greatercarbon emissions for the wood- and theconcrete bridge.The life-cycle cost analysis wascalculated with a lifespan of 40 yearsand covers the basic cost of investment,operating and maintenance, anddecommissioning costs.The analyzed constructions in this studyare existing projects that are almostcompleted. Both bridges were designed tohandle loads up to 60 tons.
En studie i användbarhet: En kritisk analys av användbarhetsstudier i biblioteks- och informationsvetenskap
Usability studies are not a central field of research in library and information science. Although literature in library and information science treats the importance of usable user interfaces quite extensively, the literature does not significantly treat potential problems in measuring usability. The aim of this master thesis is to investigate, through a critical analysis, the methods used when conducting usability studies in library and information science. The critical analysis is based on potential problems in measuring usability identified through a literature review from the field of studies Human-Computer Interaction, the concept of usabilitys original domain. The material which is to be analysed, is chosen from one library and information science journal Journal of the American Society for Information Science and Technology.
Alarm på bryggan : trygghet och irritation
Arbetet på fartygsbryggor består till en stor del av kontrolluppgifter. Operatörerna, bryggteamet, har därför kontroll- och alarmsystem till förfogande. Samspelet mellan människa och system beror delvis på användarens kunskaper och erfarenheter och delvis på bryggdesign och teknikens användarvänlighet. Arbetets ämne är hanteringen av alarm och alarmsystem på fartygsbryggor. Syftet var att undersöka om det finns strategier för detta och i så fall att belysa hur dessa strategier ser ut. Därför undersöktes sju styrmäns erfarenheter med kvalitativa metoder, med halvstrukturerade intervjuer och med innehållsanalys.
Undersökning av Södra-transportörernas användande av KOLA-systemet
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.
Synen på arbetskraftens fria rörlighet - hot elle tillgång? ? en diskursanalys av Sveriges och EU-kommissionens tal om arbetskraftens fria rörlighet före och efter Europeiska Unionens östutvidgning 2004
The aim of this thesis is to study perceptions around the freedom of movement of workers within the EU before and after its enlargement in 2004, both on a Swedish and a European level. I have chosen to conduct my study using a discourse analysis as a structure for my theory and method. Theories based on previous research have also been used. My material consists of Communications from the European Commission, Swedish Command Papers as well as a research report. One of the main findings is that at a Swedish level, there is concern about how the free movement of workers will affect the labour market and welfare system.
Torkad eller gastät lagrad spannmål till värphöns : en fallstudie
The purpose with this study is to compare different systems of grain storage from a
financial point of view. Grain that is supposed to be fed to laying hens.
The systems that were compared were different airtight storage of grain and a system of
conventional storage.
To make this case study I choose to compare four different systems. In the case study
there was one system with bin drying of the grain, two systems with airtight storage of
the grain and one system where you buy dried grain during the season.
I made several of capital investment appraisal where I found the cost of each system,
then I took the cost and divided it with the total grain use and calculated the cost for
each kilogram of grain, and also the cost of the feed.
Then I compared the cost from my case study with the cost of buying feed.
All the systems except for one, gave a lower cost for the hen feed than buying feed from
a dealer The best system, witch were bin drying lower the cost with about 80 000:- SEK.
Bättre med Scrum? : En studie om den "nya" utvecklingsmodellen
The Thesis purpose is in the context of system development validate the Scrum Methodology. Projects concerning information technology are difficult to manage and tend to fail in quality, time or costs. Scrum presents a new view of the system development. Better cooperation between customers and developers, continuous follow-up on daily basis and extensive communication in the development team are all characteristics of Scrum. Scrum is described as a new paradigm by its founders but has been criticized by experts of system development too.
