  1. 1. Underwater Positioning

    Författare :Patric Jansson; Lars Sjöberg; KTH; []
    Nyckelord :;

    Sammanfattning : The project underwater positioning was initiated by the Swedish National Road Administration (SNRA) in 1990. The aim of the project is to study positioning techniques and methods which can be used to position and locate man-made structures and features, especially engineering structures, piles for the foundation*laying of bridge pillars, in shallow water.

    Sammanfattning : Emerging wireless technologies increase the potential and effectiveness of wireless Real-time Locating Systems (RTLSs), which precisely localize the position, and identify things and people in real time. Among many applications, RTLSs are widely used in the industrial sector for indoor logistics and safety applications. LÄS MER

  4. 4. Studies of Atmospheric Water Vapor Using the Global Positioning System

    Författare :Ragne Emardson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; troposphere; microwave radiometry; climatology; radiosondes; atmospheric water vapor; Global Positioning System; time series analysis; VLBI; space geodesy; GPS; Very Long Baseline Interferometry; meteorology; radio wave propagation; Kalman filtering;

    Sammanfattning : Atmospheric water vapor is of fundamental interest in the Global Positioning System (GPS) and Very Long Baseline Interferometry (VLBI) techniques. These techniques are based on the timing of radio waves propagating through the atmosphere. LÄS MER

  5. 5. Patient Positioning in Radiotherapy Using Body Surface Scanning

    Författare :Kenneth Wikström; Anders Ahnesjö; Sven Bäck; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiotherapy; positioning; body surface; laser scanning; cancer; SGRT; ITV; lung cancer; surrogate; tumour motion; 4DCT; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : External radiotherapy uses ionising radiation to damage the DNA of the tumour cells and thereby inhibit their uncontrolled proliferation. The technical development regarding imaging and visualisation for radiotherapy has increased considerably during the last decades. LÄS MER
