  2. 2. Microwave Measurement Systems for In-line 3D Monitoring of Pharmaceutical Processes

    University dissertation from Chalmers University of Technology

    Author : Livia Cerullo; Chalmers tekniska högskola.; Chalmers University of Technology.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pharmaceutical processes; microwave measurements; permittivity; moisture content; dispersive media; finite element method; microcrystalline cellulose;

    Abstract : The monitoring and understanding of pharmaceutical processes are important in order to achieve high-quality products at a low-production cost. The presence of water, e.g. as moisture content in the solid-state pharmaceutical material, is ofparticular interest and importance. READ MORE

  3. 3. Planar segmentation for Geometric Reverse Engineering using data from a laser profile scanner mounted on an industrial robot

    University dissertation from Örebro : Örebro universitet

    Author : Mohamed Rahayem; Örebro universitet.; [2008]
    Keywords : Natural Sciences Computer and Information Science Information Science; Naturvetenskap Data- och informationsvetenskap Systemvetenskap; Geometric Reverse Engineering; 3D measurement systems; laser scanner; planar segmentation; region-growing; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science Computer and systems science; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap Data- och systemvetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Abstract : Laser scanners in combination with devices for accurate orientation like Coordinate Measuring Machines (CMM) are often used in Geometric Reverse Engineering (GRE) to measure point data. The industrial robot as a device for orientation has relatively low accuracy but the advantage of being numerically controlled, fast, flexible, rather cheap and compatible with industrial environments.

  4. 4. Range Camera Imaging : From Human Body Measurements to Very Large 3D Points Scenes Visualization

    University dissertation from Chalmers University of Technology

    Author : Gaël Neuez; Chalmers tekniska högskola.; Chalmers University of Technology.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN; MEDICINE; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; body scanner; range camera; structured light; anatomical landmarks; EASYTEX; 3D visualization; 2D image projections; octree data structure;

    Abstract : The use of camera range imaging for the purpose of 3-dimensional representation and non-contact measures is widely used in industry, medicine, computer-aided design and other areas. Different range imaging methods can be applied, such as stereo, laser sheet of light, and structured light. READ MORE

  5. 5. Track circuits’ robustness Modeling, measurement and simulation

    University dissertation from Chalmers University of Technology

    Author : Emilio Rodriguez; Luleå University of Technology.; Luleå University of Technology.; Luleå University of Technology.; [2014-11]
    Keywords : Electrical engineering; electronics and photonics Track circuit Relay False positive signals Telecommunication Signalling in railway Computer engineering Modelling Simulation Engineering physics Testing Robustness Interoperability Reliability Systems engineering Railway Infrastructure;

    Abstract : In countries with rough weather conditions, frequent delays cause railway companies to waste time and money. Many of these delays are related to the train detection systems, as the old DC track circuits are still used in some countries, including Sweden, our case study. READ MORE
