1. 1. Tree stem diameter estimation from terrestrial point clouds

   Författare :Mona Forsman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Forest owners, governments, and environmental organizations demand forest information for planning of forest operations, estimation of value, and for environmental monitoring. This information is collected using airborne and satellite remote sensing combined with field inventory of sample plots. LÄS MER

3. 2. On Service Optimization in Community Network Micro-Clouds

   Författare :Nuno Apolonia; Leandro Navarro; Sarunas Girdzijauskas; Felix Freitag; Vladimir Vlassov; Dino Lopez; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; micro-clouds; Community Networks; cloud services; social networks; overlay networks; distributed systems; Datalogi; Computer Science;

   Sammanfattning : Internet coverage in the world is still weak and local communities are required to come together and build their own network infrastructures. People collaborate for the common goal of accessing the Internet and cloud services by building Community networks (CNs).The use of Internet cloud services has grown over the last decade. LÄS MER

4. 3. Remote sensing of ice clouds : synergistic measurements and radiative transfer simulations

   Författare :Gerrit Holl; Gerald Mace; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

   Sammanfattning : This thesis primarily considers the spaceborne remote sensing of ice clouds and frozen precipitation. Ice clouds are important for hydrology and for the Earth’s radiation budget, but many properties are difficult to measure, in particular using spaceborne instruments. LÄS MER

5. 4. Mapping and Merging Using Sound and Vision : Automatic Calibration and Map Fusion with Statistical Deformations

   Författare :Gabrielle Flood; Matematik LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time of arrival; TOA; Time-difference of arrival; TDOA; Subsample methods; Uncertainty measure; Constant offset; RANSAC; Map merging; Map fusion; Change detection; Collaborative SLAM; Structure from motion; SfM; SLAM; Mapping; Localisation; Registration; Sparse maps; Point clouds;

   Sammanfattning : Over the last couple of years both cameras, audio and radio sensors have become cheaper and more common in our everyday lives. Such sensors can be used to create maps of where the sensors are positioned and the appearance of the surroundings. LÄS MER

7. 5. A Framework for Systematic use of Realistic Visualisation to Support Layout Planning of Production Systems

   Författare :Erik Lindskog; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; layout planning; visualisation; manufacturing systems; point clouds; production systems; 3D laser scanning;

   Sammanfattning : The process of designing production systems comprises a sequence of steps toward the final design and realisation. Layout planning is a significant part of this process. Its outcome should be a layout which matches the existing spatial conditions of the factory building and desired performance of the production system. LÄS MER
