  2. 21. Acoustic Sound Source Localisation and Tracking : in Indoor Environments

    Author : Anders Johansson; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Room acoustics; Speaker localisation; Tracking; State-space filter; Sequential Monte Carlo method; Particle filter;

    Abstract : With advances in micro-electronic complexity and fabrication, sophisticated algorithms for source localisation and tracking can now be deployed in cost sensitive appliances for both consumer and commercial markets. As a result, such algorithms are becoming ubiquitous elements of contemporary communication, robotics and surveillance systems. READ MORE

  4. 22. Towards a simulation methodology for prediction of airborne wear particles from disc brakes

    Author : Jens Wahlström; Ulf Olofsson; Jens Wahlström; KTH; []
    Keywords : Disc brakes; Airborne wear particles; Particle coefficient; Friction; Mechanical engineering; Maskinteknik;

    Abstract : During braking, both the rotor and the pads in disc brakes are worn. Since disc brakes are not sealed, some of the wear particles generated can become airborne. READ MORE

  5. 23. Measurements of Angular Correlations in Minimum Bias Events and Preparatory Studies for Charged Higgs Boson Searches at the Tevatron and the LHC

    Author : Camille Bélanger-Champagne; Claus Buszello; Tord Ekelöf; Nick van Remortel; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ATLAS; D0; LHC; Tevatron; CERN; Fermilab; QCD; Monte Carlo tunes; Matrix Element method; Charged Higgs boson; Tau lepton; Trigger; Physics; Fysik; Elementary particle physics; Elementarpartikelfysik; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : Studies of minimum bias events at colliders probe the behavior of QCD in the non-perturbative regime. The phenomenology of events in this regime is described by empirical models that take many parameters, which all need to be tuned to the observed data. READ MORE

  6. 24. Monte Carlo particle transport codes for ion beam therapy treatment planning : Validation, development and applications

    Author : Till Tobias Böhlen; Irena Gudowska; Oliver Jäkel; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo; ion beam therapy; treatment planning; cancer therapy; microdosimetry; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : External radiotherapy with proton and ion beams needs accurate tools for the dosimetric characterization of treatment fields. Monte Carlo (MC) particle transport codes, such as FLUKA and GEANT4, can be a valuable method to increase accuracy of dose calculations and to support various aspects of ion beam therapy (IBT), such as treatment planning and monitoring.

  7. 25. Dose estimation in space using the Particle and Heavy-Ion Transport code System (PHITS)

    Author : Katarina Gustafsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The radiation risks in space are well known, but work still needs to be done in order to fully understand the radiation effects on humans and how to minimize the risks especially now when the activity in space is increasing with plans for missions to the Moon and Mars.One goal is to develop transport codes that can estimate the radiation environment and its effects.
