Automatisk Identifiering av Inandningspauser i Spontant Tal - ett HMM/ANN-hybridsystem i Matlab

This thesis presents a system which has been implemented to satisfy a need in theresearch on how speech planning interacts with syntactic and prosodic structure inspontaneous speech. The long-term purpose of the research is to provide models forautomatic parsing of spontaneous speech and for psycholinguistical modelling of speechproduction. Identification of inhalation pauses is an important step in the developmentof automatic methods for spontaneous speech parsing.Identification of inhalation pauses is considered to be a keyword-spotting speechrecognition problem. Hybrid HMM(Hidden Markov Models)/ANN(Artificial NeuralNetworks) approach is applied to this problem. Method gets 90,8% in Recall, 66,4% inPrecision and 76,7% in F-score.

"Det är så lätt, det är bara att gå in och trycka på ett par knappar." En rättssociologisk utvärderingsstudie av lagen om upphovsrätt (Lag 2005:359) och de viktigaste orsaksmekanismerna bakom fildelning

The purpose of this study was to find out why the law that regulates downloading copyrighted material does not work and which of the most important main reasons lies behind downloading behaviour. The phenomenon being well investigated earlier has actualized a new demand for normative investigation in connection with the hot debated IPRED-law.Using qualitative method comprising of interviews with three typical file sharers and anchored in Max Webers action typology, rational choice theory and the norm model followed by two assessment models, we found that four important reasons lies behind downloading behaviour: 1) economical reasons was the most central and frequent determinant followed by 2) accessibility and comfort, and 3) social acceptance and moral and also 4) habits. Although the content of the law was correctly provided by the interviewees, it was clear that they did not perceive the impact of the law as meaningful or threatening.The results, being compatible with previous research, are discussed in terms of the named theories and assessment models. We suggest further research to take into account peoples norms as the new IPRED-law soon will be functional as well as studies from a perspective of the legal rights of the individual..

Bidragsanalys av dimensioner och postningar : en studie vid Vida Alvesta

An old and well known problem in sawmilling is to determine which dimensions /products those are most profitable to produce. Existing optimization models maximize the value of the log. In other words, based upon the market prices of the dimensions the models calculate the best way to split the log. Yet there is a great uncertainty if the most well paid dimensions really are the most profitable to produce. The costs of the process from lumber to sawn products are hard to determine and are therefore often left out from the optimization process. In this study the economic contribution of different dimensions/products are analysed.

CAPM - i tid och otid : En portföljbaserad studie av CAPM på den svenska aktiemarknaden

Capital Asset Pricing Model (CAPM) är den prissättningsmodell som mest frekvent används av aktörer på den finansiella marknaden samt i litteratur för att förklara sambandet mellan risk och förväntad avkastning. Teorin grundades under 1960-talet av William Sharpe och tidiga empiriska tester av modellen visade att den med hög förklaringsgrad kunde estimera en framtida förväntad avkastning givet en viss risknivå. På senare år har dock CAPM fått stark kritik eftersom nya empiriska undersökningar demonstrerat att modellen inte längre verkar visa en rättvisande avkastning i förhållande till risk.För att undersöka om den över 40 år gamla modellen fortfarande visar någorlunda rättvisande beskrivningar av verkligheten har vi ställt oss frågan: Går det att med hjälp av historiska data förutspå en riskfylld tillgångs avkastning på den svenska aktiemarknaden?Vid besvarade av denna fråga har studien syftet Att med hjälp av portföljer studera huruvida sambandet mellan risk och avkastning, vilket postuleras av CAPM, stämmer på den nutida svenska aktiemarknaden.Vi har utifrån vår kunskapssyn kritisk rationalism använt oss av en kvantitativ metod för att försöka ge svar på problemställningen, vilken angreps med ett deduktivt tillvägagångssätt. Den teoretiska referensramen behandlar teorier som portföljval, den effektiva marknadshypotesen och CAPM.

2001: ett e-äventyr : Implementering av e-böcker i det digitala biblioteket

Rapid development in the realms of electronic publishing has had a profound impact on information services in general and the academic library in particular. Since mid 1990´s an increasingly number of scholarly journals and other information resources have been made available electronically. Electronic books are the newest electronic service in the hybrid library and can be seen as the third wave in the digital library. Although electronic books have for a long time existed as electronic texts such as digitalized classics or other texts in the public domain, it is not until recently that e-books have been distributed and packaged in a commercial form. As more e-book models are being developed, libraries are being forced to take e-books into consideration when planning their information services.The aim of this master thesis is to describe the first stage of implementation of the new electronic media, the electronic book or e-book, in Swedish academic libraries.

Den svenska swapspreadens förklaringsfaktorer : en empirisk analys

This paper presents empirical evidence on the determinants of interest rate swap spreads in Sweden during the period 1999-2003. The results suggest that the spread between STIBOR and the general collateral repo rate is positively related to shorter maturity swap spreads. The risk premium associated with commercial bonds is positively related to swap spreads of all maturities. A negative relationship is observed between the term structure of interest rates and swap spreads. The short-term interest rate is positively related to spreads with shorter maturities.

Analysverktyg för webbsidor med JavaScript

New technological innovations like tablets and smartphones have a taken significant market share on the web and puts new demands on webpages, the user interface and compatibility among different client devices. The full test of a web-based system prior to the publication is often regarded as an important part of the process to create a complete and successful website. This bachelor thesis investigates the possibility to analyze mobile-adapted web sites using a system that first records the visitor's activities and then replays them for an expert analyst to provide valuable information to developers about how their site can be improved.The essay begins with a litterature study on today's most common web development tools and then examines the possibility to apply them during the development of the analysis tool. The work also describes two methods, pair programming and waterfall method used during the project. Three different evaluation methods are presented and one of the models is applied on the finished system.The project results in a web-based analysis tool written mainly in JavaScript using the jQuery library.

En undersökning av Bergvik skogs och Skogsstyrelsens gallringsmallar mot en gallringsoptimering på simulerade typbestånd

The purpose of this study was to analyze the two thinning models: Bergvik Skog´s thinning model, which is based on total stems and dominant height, And Swedish forest agency´s thinning model which is based on basal area, habitat index, dominant height and recommended number of stems at final felling in Heureka´s StandWise and PlanWise. The data we chosen for our study were taken from the Swedish National Forest Inventory and we were creating a simulated stand based on a great number of sample plots in Region three from The Swedish National Forest Inventory. We had chosen to create one stand with low habitat index (T20) and one with high habitat index (T24). Our purpose were to come as close as possible to a natural stand in central Sweden. We performed the thinning in StandWise and analyzed the data I Excel files. Our thinning optimizing´s were performed and analyzed in PlanWise. There wasn´t any big differences between the thinning on the lower habitat index.

Transnationell kooperation : en studie av DLA Agro

Farmers Cooperative has in recent years developed from national markets to cross-border, international, collaborations. One example is the merger between the Swedish dairy company Arla and Danish MD Foods, where the companies collectively are sought to reduce transaction costs and thus improve efficiency. The Swedish market for commodities (fertilizers and pesticides) in agriculture has for many years been dominated by a few large players, with little opportunity for grain associations and local grain companies to offer their customers a varied range of commodities with a competitive pricing.To change this state, a majority of Swedish and Danish grain associations and local grain companies have established a trans-national cooperation. Through the establishment of the organization DLA Agro, they offer their customers a good variety of products with competitive prices. This study investigates thus according to the theory of cooperative models to what extent and how the DLA Agro helps to create benefits for the Swedish member companies.

Simulering av simulinkmodeller med Extended Kalman Filter

Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.

Förslag på riskklassificeringsmodell av ekologiskt kontrollerade aktörer : En jämförelse med andra länders ekologiska kontroll

In order to facilitate trade between EU members, the European Committee has created regulations that will govern supervision of organic products. Every regulatory agency shall, according to the European Committees regulations, carry out a risk classification of each organic producer they regulate. This study for The National Food Administration compares regulation of Swedish organic products with other countries, and aims to produce a simplified model based on risk that can be the beginning of the risk classification model that Sweden in the current situation don?t have. The thesis is based on three questions: 1) What criteria should we use for assigning organic food producers? 2) How do selected European countries and frontrunners rate organic producers and what can Sweden learn from them? 3) How might a national classification model of organic production look in order to ensure an equivalent level of regulation and prevent competition among private inspection bodies? A review of information gathered from the different countries gave differing results.

Utvärdering av metoder för framställning och kontroll av digitala terrängmodeller

Today there are many applications of digital terrain models (DTM) and the requirements of low uncertainty increases. Most of the DTM are produced with Global Navigation Satellite System (GNSS), terrestrial laser scanning (TLS), airborne laser scanning (ALS) and total stations. Guidelines for the preparation and verification of DTM are found in Swedish Standards Institute ? Technical Specifications (SIS-TS) 21144:2007 and SIS-TS 21145:2007. These were defined in collaboration between Swedish National Rail Administration, Banverket, and Swedish Road Administration, Vägverket, to satisfy the needs of requirement formulations in the production of DTM planning, design and construction. The purpose of this paper is to produce and control DTM over Åkermans kulle, located west of the University of Gävle, according to SIS TS 21144:2007 using GNSS with network-RTK, TLS and ALS.
