2. 1. The Integration of 3D Geodata and BIM Data in 3D City Models and 3D Cadastre

   Author : Jing Sun; Kent Eriksson; Anders Östman; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D geodata; BIM; city models; 3D cadastre; geometric quality; CityGML; LADM; laser scanning; Geodesy and Geoinformatics; Geodesi och geoinformatik; Geodesi; Geodesy;

   Abstract : The initial geographic information system (GIS) and building information modelling (BIM) are designed and developed independently in order to serve different purposes and use. Within the prolific increase and growing maturity of three-dimensional (3D) technology, both 3D geodata and BIM data can specify semantic data and model 3D buildings that are prominent for the 3D city models and 3D cadastre.

4. 2. 3D Reconstruction of Porous and Poorly Conductive Soft Materials using FIB-SEM Tomography

   Author : Cecilia Fager; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; insulating material; 3D; interconnectivity; focused ion beam; tomography; polymer film; scanning electron microscopy;

   Abstract : Focused ion beam combined with scanning electron microscope (FIB-SEM) is a powerful tool that can be utilised to reveal the internal microstructure of materials. It basically uses ions to make cross-sections with high precision and electrons to image the cross-section surface with high spatial resolution. READ MORE

5. 3. Quantitative 3D reconstruction of porous polymers using FIB-SEM tomography -correlating materials structures to properties of coatings for controlled drug release

   Author : Cecilia Fager; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; tomography; controlled drug release; 3D; connectivity; insulating material; polymer film; soft material; focused ion beam; scanning electron microscopy;

   Abstract : Porous networks are found in a wide range of different advanced and technologically important materials and influence the materials properties. The networks are active components in for example batteries, food and pharmaceuticals. The interconnectivity of a network strongly influences the transport properties. READ MORE

6. 4. Development of intelligent robot systems based on sensor control

   Author : Mikael Fridenfalk; Institutionen för elektro- och informationsteknik; []

   Abstract : Sensor based control systems increase flexibility and autonomy in robotics. One of the most common applications in robotics is welding, which is often limited to objects with fine tolerances. READ MORE

7. 5. Calibration Procedure and Industrial Applications of Coherence Scanning Interferometer

   Author : Olena Flys; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coherence Scanning Interferometer; Power Spectral Density; 3D parameters; Characterization; uncertainty;

   Abstract : Countless industrial applications over the past decades have indicated the increased need to relate surface texture to surface function. Measurement and characterization of the areal nature of the surface allows the manufacturer to alter how the surface interacts with surroundings. READ MORE
