1. 1. Miljöinvesteringar i svensk transportnäring : Drivkrafter och strategier

   Författare :Janni Jensen (Nilsson); Olof Hjelm; Magnus Blinge; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Miljö; miljöinvesteringar; investeringar; investeringskalkyler; transporter; godstransporter; strategier; Business studies; Företagsekonomi;

   Sammanfattning : The environmental work in the Swedish transportation business was not very prioritized during the period up until 1990. If any environmental work occurred at all, it often entailed only necessary measures to meet the demands of environmental law.All this changed almost over night roundabout 1990. LÄS MER

3. 2. Aspects of cash-flow valuation

   Författare :Fredrik Armerin; Boualem Djehiche; Bjarne Astrup Jensen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; arbitrage; coherent and convex measures of risk; immunization; insurance; martingale methods; Matematisk statistik; Mathematical statistics; Matematisk statistik;

   Sammanfattning : This thesis consists of five papers. In the first two papers we consider a general approach to cash flow valuation, focusing on dynamic properties of the value of a stream of cash flows. The third paper discusses immunization theory, where old results are shown to hold in general deterministic models, but often fail to be true in stochastic models. LÄS MER

4. 3. On practical machine learning and data analysis

   Författare :Daniel Gillblad; Anders Lansner; Finn Jensen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datalogi;

   Sammanfattning : This thesis discusses and addresses some of the difficulties associated with practical machine learning and data analysis. Introducing data driven meth- ods in e. g. industrial and business applications can lead to large gains in productivity and efficiency, but the cost and complexity are often overwhelm- ing. LÄS MER

5. 4. Entropy and Speech

   Författare :Mattias Nilsson; Bastian Kleijn; Sören Holdt Jensen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speech representation; energy concentration; entropy estimation; manifolds; Acoustics; Akustik;

   Sammanfattning : In this thesis, we study the representation of speech signals and the estimation of information-theoretical measures from observations containing features of the speech signal. The main body of the thesis consists of four research papers. Paper A presents a compact representation of the speech signal that facilitates perfect reconstruction. LÄS MER

7. 5. Some New Contributions in the Theory of Hardy Type Inequalities

   Författare :Markos Fisseha Yimer; Sorina Barza; Lars-Erik Persson; Martin Lind; Liviu-Gabriel Marcoci; Lubos Pick; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; integral inequalities; Hardy-type inequalities; Pólya-Knopp’s inequality; Jensen’s inequality; Minkowski’s inequality; Beckenbach-Dresher’s inequality; sharp constants; measures; superquadratic functions; refinements; Banach function spaces; Matematik; Mathematics;

   Sammanfattning : In this thesis we derive various generalizations and refinements of some classical inequalities in different function spaces. We consider some of the most important inequalities namely the Hardy, Pólya-Knopp, Jensen, Minkowski and Beckenbach-Dresher inequalities. The main focus is put on the Hardy and their limit Pólya-Knopp inequalities. LÄS MER
