  1. 1. On suicide in European countries : some theoretical, legal and historical views on suicide mortality and its concomitants

    Detta är en avhandling från Stockholm : Almqvist & Wiksell International

    Författare :Ilkka Henrik Mäkinen; Stockholms universitet.; [1997]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SOCIAL SCIENCES Social sciences Sociology; SAMHÄLLSVETENSKAP Socialvetenskap Sociologi; Attityd; dödlighet; historia; lag; kultur; självmord; teori; Sociology; sociologi; assisted suicide; comparative studies; cross-sectional studies; culture; Durkheim; Europe; history; law; modernization; Parsons; suicide; suicide rates; Sweden; theories;

    Sammanfattning : The theme of this thesis is suicide mortality in its various aspects, seen from an international, European perspective. It questions the existence of social (structural) concomitants to suicide mortality and investigates attitudes towards and legislation concerning suicide, as well as some historical processes pertaining to their development.

  2. 2. InP-based photonic crystals Processing, Material properties and Dispersion effects

    Detta är en avhandling från Stockholm : KTH

    Författare :Audrey Berrier; KTH.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photonic crystals; indium phosphide; photonic bandgap; Bloch modes; slow light; dispersion; coupled cavity waveguides; chemically assisted ion beam etching; lag effect; cavities; optical losses; carrier transport; carrier lifetimes; negative refraction; photonic bandstructure; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Sammanfattning : Photonic crystals (PhCs) are periodic dielectric structures that exhibit a photonic bandgap, i.e., a range of wavelength for which light propagation is forbidden. The special band structure related dispersion properties offer a realm of novel functionalities and interesting physical phenomena. LÄS MER

  3. 3. Study on electroabsorption modulators and grating couplers for optical interconnects

    Detta är en avhandling från Stockholm : KTH

    Författare :Yongbo Tang; KTH.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photonic integrated circuit; optical interconnect; transmission line; traveling-wave; electro-absorption modulator; hybrid silicon evanescent platform; grating coupler; vertical coupling scheme; optical antenna; lag effect; polarization beam splitter; TECHNOLOGY Electrical engineering; electronics and photonics Photonics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Fotonik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Decades of efforts have pushed the replacement of electrical interconnects by optical links to the interconnects between computers, racks and circuit boards. It may be expected that optical solutions will further be used for inter-chip and intra-chip interconnects with potential benefits in bandwidth, capacity, delay, power consumption and crosstalk.

  4. 4. A fixed-lag smoother for solving joint input and state estimation problems in structural dynamics

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Ulrika Lagerblad; KTH.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Joint input-state estimation; Fixed-lag smoother; Structural dynamics; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : In this thesis we have investigated different numerical filters for joint input and state estimation, with the aim of designing a robust algorithm capable of monitoring the continuous motion and loading in a truck chassis. The algorithm has to be able to use sparse measurements of the motion on different parts of the truck as it is excited by road induced vibrations, and transform this data into knowledge of the state in the entire system.

  5. 5. Bacterial and fungal growth in soil: The effect of temperature and substrate addition

    Detta är en avhandling från Department of Biology, Lund University

    Författare :Stephanie Reischke; Lunds universitet.; Lund University.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bacterial growth; Fungal growth; Respiration; Carbon loading; Glucose mineralisation; Temperature adaptation; Temperature sensitivity; Temperature dependence;

    Sammanfattning : Bacteria and fungi are the main agents in decomposition of soil organic matter. Their activity is determined by the availability and quality of substrate, especially its content of carbon, but also nitrogen and phosphorus. Other environmental factors, which affect the activity of the microbial community in soil, are temperature, moisture and pH. LÄS MER
