  3. 2. Influence of middle ear pressure changes on labyrinthine hydrodynamics and hearing physiology

    Författare :Konrad Konradsson; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; auditive system and speech; audiology; Pressure; Audiometry; Cats; Animal; Cochlea; Cochlear aqueduct; Ear; Eustachian tube; Hearing; Otorinolaryngologi; Human; Labyrinth; Otorhinolaryngology; Meniere s disease; audiologi; hörsel- och talorganen;

    Sammanfattning : Results from experimental studies, as well as clinical studies, are used to elucidate the effects of ambient pressure changes on cochlear hydrodynamics and function. The perilymph pressure changes and the pressure release effects of the cochlear aqueduct (CA) and Eustachian tube (ET) in cats exposed to hypobaric pressure are elucidated. LÄS MER

  4. 3. Urban Snowmelt Processes: Modelling and Observation

    Författare :Annette Semadeni Davies; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; energy; runoff; snow properties; heterogeneity; hydrological modelling; Urbanisation; snowmelt; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Sammanfattning : In northern Scandinavia and other cold regions, urban drainage systems are often unable to cope with the high volumes of melt water which can be sustained for several weeks. High waste water treatment plant inflows, combined system overflows and low water quality are a few problems associated with snowmelt. LÄS MER

  5. 4. Towards Correct and Efficient Program Execution in Decentralized Networks: Programming Languages, Semantics, and Resource Management

    Författare :Karl Palmskog; Mads Dam; Rocco De Nicola; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; distributed objects; decentralization; implementation correctness; network protocols; object mobility; Computer Science; Datalogi;

    Sammanfattning : The Internet as of 2014 connects billions of devices, and is expected to connect tens of billions by 2020. To meet escalating requirements, networks must be scalable, easy to manage, and be able to efficiently execute programs and disseminate data. The prevailing use of centralized systems and control in, e.g. LÄS MER

  7. 5. Micro- and Millimeter Wave CMOS Beamforming Receivers

    Författare :Andreas Axholt; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beamforming; CMOS; front-end; microwave; millimeter wave; phase-locked loop; phased-array;

    Sammanfattning : The available bandwidth in wireless communication systems, such as the 802.11 family, is very limited. Together with the ever increasing data traffic, this causes problems. New possibilities are, however, available thanks to wide license-free bandwidth allocated at higher frequencies. LÄS MER
