  1. 21. Acoustic time histories of vibrating partial sources

    Författare :Nicklas Frenne; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : The research in this thesis evaluates a method designed for separation of individual or partial sounds from multiple sounds generated by a sound source (e.g. a diesel engine). The sound of sound sources can be recorded to reproduce a sound event in an environment, just like a photo or moving picture can be used to illustrate a visual impression. LÄS MER

  3. 22. Performance of landfills of hazardous waste with special respect to the function of clay liners

    Författare :Laith Al-Taie; Rolf Sjöblom; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : This licentiate thesis is based on four papers related to the performance of near-surface low-level (LLW) repositories (landfills) focusing on construction and performance of clay liners in the cappings. The first paper discusses the source of hazardous wastes, their location and their impact on public health. LÄS MER

  4. 23. Terpenoid Plant Metabolites - Structural Characterization and Biological Importance

    Författare :Eliana Maldonado; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Terpenoid Sesquiterpene lactones Breast-cancer cell lines Cytotoxicity Antileishmanicial Structural characterization;

    Sammanfattning : In response to the challenges of their local environments, organisms produce of a large number of chemical diverse compounds with complex stereochemistry and reactive functional groups. These characteristics enable them to interact and bind specifically to biological target molecules and exert various biological activities, and have assured that Natural products continues to be an important source of bioactive compounds, which, for example, facilitate the search for new lead structures that can be developed into new pharmaceuticals.

  5. 24. Towards a Predictable Component-Based Run-Time System

    Författare :Rafia Inam; Mikael Sjödin; Jukka Mäki-Turja; Tullio Vardanega; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; real-time systems; component based software engineering; hierarchical scheduling; Computer Science; datavetenskap;

    Sammanfattning : In this thesis we propose a technique to preserve the temporal properties of realtime components during their integration and reuse. We propose a new concept of runnable virtual node which is a coarse-grained real-time component that provides functional and temporal isolation with respect to its environment. LÄS MER

  7. 25. Self-Switching Diodes for Zero-Bias Terahertz Detection

    Författare :Andreas Westlund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; self-switching diode; noise-equivalent power; SSD; graphene; zero-bias; InAs; InGaAs; terahertz; detector;

    Sammanfattning : The self-switching diode (SSD) has been investigated as a potential terahertz detector in recent years. The SSD accomplishes a non-linear current-voltage relation through a field-effect, which enables detection at zero bias from microwave up to terahertz frequencies. In this work, SSDs were realised in two new materials; InAs and graphene. LÄS MER
