  1. 1. Turbulent jets in confined spaces : application in mixing ventilation: experimental and numerical studies

    Författare :Taghi Karimipanah; Mats Sandberg; H. A. Awbi; Högskolan i Gävle; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; turbulent; wall jet; impinging jet; free jet; confinement effect; pressure; throw; experimental; numerical; corner; momentum; mixing ventilation;

    Sammanfattning : The basis of mixing ventilation is the airflow supply to the room by means of jets initiatedfrom the ventilation diffusers. To avoid the draught problem, the design of mixing ventilationmakes uses the throw term, which is defined as the distance to the supply air terminal inwhich the jet centreline mean velocity is decreased to a given value.

  2. 2. Windstorms in Sweden - variations and impacts

    Författare :Carin Nilsson; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate impact; geostrophic wind; Gudrun; Anatol; wind throw; forest damage; storm damage; Sweden; wind climate; windstorm;

    Sammanfattning : Windstorms have caused severe damage on several occasions in Sweden during the last century. A general concern about future projections of climate extremes has raised questions on the variations and impacts of windstorms. LÄS MER

  3. 3. We belong to them : Narratives of belonging, homeland and nationhood in territorial and non territorial minority settings

    Författare :Tünde Puskás; Rune Johansson; Yngve Lithman; Linköpings universitet; []
    Nyckelord :Everyday ethnicity; long-distance nationalism; Hungarian nation politics; ethnic and national identifications; Hungarians in Slovakia; Hungarians in Sweden; homeland narratives; language ideologies and language dilemmas; Vardagsetnicitet; distansnationalism; ungersk nationspolitik; etniska och nationella identifikationer; ungrare i Slovakien; ungrare i Sverige; hemlandsberättelser; språkideologier och språkdilemman; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : This dissertation explores what happens with ethnic and national identifications buiit on the same ethnocultural grounds, but under different socio-economic circumstances. Territorial and nonterritorial minorities have traditionally been considered non-comparable because it was assumed that groups organized on different grounds were distinctively separate phenomena.

  4. 4. Submillimeter-Wave Waveguide Frontends by Silicon-on-Insulator Micromachining

    Författare :Adrian Gomez-Torrent; Joachim Oberhammer; Umer Shah; Goutam Chattopadhyay; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antenna; orthomode transducer; switch; waveguide; radiofrequency; beamforming network; submillimeter-wave; terahertz; silicon micromachining; deep reactive ion etching; silicon on insulator; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis presents novel radiofrequency (RF) frontend components in the submillimeter-wave (sub-mmW) range implemented by silicon micromachining, or deep reactive ion etching (DRIE). DRIE is rapidly becoming a driving technology for the fabrication of waveguide components and systems when approaching the terahertz (THz) frequency range. LÄS MER

  5. 5. A lighter UDP

    Författare :Lars-Åke Larzon; Luleå tekniska universitet; []
    Nyckelord :;

    Sammanfattning : With the advent of IP telephony and other real time multimedia applications running atop new wireless networks, new problems arise for the traditional Internet stack of protocols. Network and transport protocol support for these new applications has not yet been fully developed and optimized. LÄS MER
