  2. 1. Essays on Lookback and Barrier Options - A Malliavin Calculus Approach

    Author : Hans-Peter Bermin; Nationalekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Girsanov transformations.; lookback options; Contingent claims; barrier options; hedging; pricing; arbitrage; complete markets; self-financing portfolios; Black-Scholes formula; Clark-Ocone formula; Malliavin calculus; Financial science; Finansiering;

    Abstract : This thesis consists of four theoretical essays on contingent claim analysis and its connection to Malliavin calculus. The first three papers are analyzed in the famous Black and Scholes model, while the setup of the fourth paper involves an international environment and the presence of exchange rates. READ MORE

    Author : Li Zha; Qi Zhou; Lars Berglund; Eero Kontturi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanocellulose; biopolymers; biocomposites; surface engineering; nanostructure; redispersibility; mechanical property; optical property; nanocellulosa; biopolymerer; biokompositer; ytteknik; nanostruktur; redispergerbarhet; mekaniska egenskaper; optiska egenskaper; Kemi; Chemistry;

    Abstract : Nanocellulose, originated from cellulose, the primary structural component of the cell walls of plants, has garnered significant attention for its excellent mechanical, optical, and barrier properties, as well as its renewable and sustainable nature. Various forms of nanocellulose, including cellulose nanocrystals and cellulose nanofibers (CNFs), are produced by breaking down lignocellulosic fibers into nanoscale dimensions, typically through mechanical or chemical processes.

  6. 4. Xyloglucan-based polymers and nanocomposites – modification, properties and barrier film applications

    Author : Joby Kochumalayil Jose; Lars Berglund; José M. Kenny; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; xyloglucan; packaging; oxygen barrier; nanocomposites;

    Abstract : Biopolymers from renewable resources are of interest for packaging applications as an alternative to conventional petroleum-based polymers. One of the major application areas for biopolymers is food packaging, where a candidate polymer should meet critical requirements such as mechanical and oxygen barrier performance, also in humid conditions.

  7. 5. Thermal barrier coatings for diesel engines

    Author : Wellington Uczak de Goes; Nicolaie Markocsan; Mohit Kumar Gupta; Rogerio S. Lima; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Barrier Coatings; Suspension Plasma Spraying; Gadolinium Zirconate; Internal Combustion Engines; Engine Efficiency; Termiska barriärbeläggningar; Plasmasprutning; Suspensionssprutning; Gadolinium; Zirkoniumdioxid; Förbränningsmotorer; Motoreffektivitet; Production Technology; Produktionsteknik;

    Abstract : The upward trend in internal combustion engine efficiency is driven by the demands for emission reduction and fossil fuel depletion. No present alternative fuel can produce energy comparable to that produced by conventional oil; this necessitates the reasonable, efficient usage of oil. READ MORE
