   Sammanfattning : This PhD study focusses on the use of MEdium Resolution Imaging Spectrometer (MERIS) data for reliable and quantitative water-quality assessment of optically-complex waters (lake, brackish and coastal waters). The thesis is divided into two parts: A. LÄS MER

3. 27. A Multi Sensor System for a Human Activities Space : Aspects of Planning and Quality Measurement

   Författare :Jiandan Chen; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D Reconstruction; Iso-disparity Surfaces; Depth Reconstruction Uncertainty; Uncertainty Analysis; Dither; Sensor Placement; Multi Stereo View; Image Quality; Human Factor;

   Sammanfattning : In our aging society, the design and implementation of a high-performance autonomous distributed vision information system for autonomous physical services become ever more important. In line with this development, the proposed Intelligent Vision Agent System, IVAS, is able to automatically detect and identify a target for a specific task by surveying a human activities space.

   Författare :Anna-Lena Lane; Mathias Cehlin; Thomas Olofsson; Högskolan i Gävle; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency gap; energy performance gap; ByggaE; battery storage; barriers; drivers; Non-energy benefits NEB; questionnaire; quality assurance; PV; energieffektivisering; energieffektiva byggnader; kvalitetssäkring; byggprocessen; ByggaE; solel; batterilager; hinder; drivkrafter; enkätstudie; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : There is a need to reduce unsustainable use of fossil fuels. Increased usage of renewable energy by combined use of photovoltaic solar panels (PV) with battery storage is one way. Another way is to increase awareness of energy usage and reduce the energy performance gap by building energy-efficient buildings. LÄS MER

5. 29. Deep Regression and Segmentation for Medical Inference from Large-Scale Magnetic Resonance Imaging

   Författare :Taro Langner; Joel Kullberg; Anders Eklund; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic resonance imaging; medical image analysis; neural networks; machine learning; semantic segmentation; deep regression; saliency analysis; uncertainty quantification; UK Biobank; Medical Informatics; Medicinsk informatik;

   Sammanfattning : Large-scale studies, such as UK Biobank, acquire medical imaging data for thousands of participants. With magnetic resonance imaging (MRI), comprehensive representations of human anatomy can be provided for non-invasive assessments of health-related conditions, body composition, organ volumes, and more.

7. 30. An Intelligent Multi Sensor System for a Human Activities Space---Aspects of Quality Measurement and Sensor Arrangement

   Författare :Jiandan Chen; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D Reconstruction; Depth Measurement; Depth Reconstruction; Dither; Human Factor; Image Quality; Iso-disparity Surfaces; Multi-Sensor System; Quality Measurement; Sensor Arrangement; Surveillance; Tracking; Uncertainty;

   Sammanfattning : In our society with its aging population, the design and implementation of a highperformance distributed multi-sensor and information system for autonomous physical services become more and more important. In line with this, this thesis proposes an Intelligent Multi-Sensor System, IMSS, that surveys a human activities space to detect and identify a target for a specific service. LÄS MER
