After a brief outlook on the field of concatenative synthesis of singing, with emphasis on the differences in comparison to synthesis of speech, the present paper gives an overview of a simple system for singing synthesis in Swedish based on concatenation of diphones. The system, called Burcas, accepts as input a text file for lyrics, from which it extracts a target phoneme sequence using basic le

Purpose: The purpose of this paper is to empirically evaluate the performance of seven different methods that are used when estimating Value-at-Risk for a portfolio of Swedish index-bonds with different maturities. As a supplementary objective, the paper tries to determine the history that one needs to account for when calculating VaR. Methodology: In order to calculate the VaR, a portfolio consi

In this paper I examine the approaches taken by actors in Scania to improve power reliability and prevent outages. This means that I study what the relevant actors do in order to detect threats and vulnerabilities to the power supply. I also study the measures they take to reduce these risks and prevent outages. From that I draw a conclusion on their approach to the issue. To categorize the organi

In recent years, the market for mobile applications has continuously grown in size, and appears to continue to grow. This means greater competition among app developing companies as the users expect applications with high usability and a great user experience. To assess these properties the companies can perform usability evaluations. However, practicing traditional usability evaluation methods ca

Visualization of molecular models is a vital part in modern drug design. Improved visualization methods increases the conceptual understanding and enables faster and better decision making. The introduction of virtual reality goggles such as Oculus Rift has introduced new opportunities for the capabilities of such visualisations. A new interactive visualization tool (MolecularRift), which lets t

Denna rapport redogör för design och utveckling av ett medicintekniskt instrument för diagnos av kronisk obstruktiv lungsjukdom (KOL) eller emfysem. Arbetet utgår ifrån en ny diagnosmetod och ett instrument i form av en funktionell prototyp som används för att testa den nya diagnosmetoden. Med utgångspunkt i den funktionella prototypen har arbetet fokuserats kring att förstå vilka problem och utmThis thesis presents design and development of a medical device for diagnosis of emphysema or COPD by controlled lung deposition of nanoparticles. After purging the lungs with particle free air the subject inhales a controlled aerosol mixture and holds his breath for a determined period of time, before exhaling. The degree of lung disease is calculated by measuring and comparing the concentration

A FT-NIR (Fourier-Transform Near Infrared) model for moisture content has been developed for whole seeds of Swedish rapeseed (Brassica napus) by the conditions given during the harvest of 2014. Compared to Internal standardized (ISO) method 665, the final model showed very small differences in terms of repeatability and measurement uncertainty even though the measurement time was four times faster

Most current methods for studying cascading effects rely on written sources to extract information. This thesis presents an empirical method for studying cascading effects, when little written information of the event is available. The method presented has been influenced by incident investigation methods. It has been applied on a case of flooding in south of Sweden and revised based on the result
