  2. 1. On norovirus outbreaks and transmission in hospitals

    Author : Carl-Johan Fraenkel; Infektionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; norovirus; outbreaks; transmission; surveillance; prevention;

    Abstract : Abstract Noroviruses are now the leading cause of gastroenteritis worldwide. Noroviruses are effectively transmitted due to a low infectious dose, viral shedding in high concentrations, environmental stability, and they induce only a limited immunity after infection. Especially, the norovirus variants of genotype II.4 (GII. READ MORE

  4. 2. Filter bank design for digital speech signal processing : methods and applications

    Author : Jan Mark de Haan; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive filter theory; Subband filter banks;

    Abstract : Adaptive filter theory is an important subject in the field of signal processing and has numerous applications in speech processing, telecommunications and mechanical engineering. Examples in speech processing include suppression of background noise, echo cancellation and dereverberation (acoustic path equalization). READ MORE

  5. 3. Path Inference of Sparse GPS Probes for Urban Networks : Methods and Applications

    Author : Mahmood Rahmani; Harilaos Koutsopoulos; Clas Rydergren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; map-matching; path inference; sparse GPS probes; FCD; urban area; digital road network; Stockholm; taxi; iMobility Lab; MapViz; travel time; SRA - Transport; SRA - Transport;

    Abstract : The application of GPS probes in traffic management is growing rapidly as the required data collection infrastructure is increasingly in place in urban areas with significant number of mobile sensors moving around covering expansive areas of the road network. Most travelers carry with them at least one device with a built-in GPS receiver. READ MORE

  6. 4. Bone Conduction Hearing in Human Communication - Sensitivity, Transmission, and Applications

    Author : Sabine Reinfeldt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transcutaneous; one s own voice; bone conduction; occlusion effect; communication system; sensitivity; bone conduction implant; transmission; bone-anchored hearing aid; bone conduction microphone;

    Abstract : Sound perceived via Bone Conduction (BC) consists of vibrations transmitted to the cochleae through the skull bone from either one's own voice, the surrounding sound field, or a BC transducer. In two-way communication systems, BC is believed to improve the sound quality when used in specific environments, e.g. READ MORE

  7. 5. Data Driven Condition Monitoring for Transmission and Axles

    Author : Elisabeth Källström; John Lindström; Magnus Karlberg; Jiri Tuma; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : As the requirements to improve up-time and thus to reduce costly down-time con-tinuously increases, the construction equipment business focuses on more and newways to increase ability and sensitivity of early fault detection of critical compo-nents and parts in order to prevent failure. Failure of critical components in theheavy duty machine may lead to unnecessary stops and expensive downtime. READ MORE
