Remotely sensed images with a pixel size of about 1 m can nowadays be acquired by airborne scanners and in the near future also by high resolution satellites. With such a high spatial resolution, remotely sensed data of urban areas can resolve structures like a roof into the different surface segments with different inclinations, e.g. in the case of a gabled roof. We have measured the BRDF (Bid...

Gable roof buildings are widely used in industrial buildings. Based on wind tunnel tests with rigid models, wind pressure distributions on gable roof buildings with different aspect ratios were measured simultaneously. Some characteristics of the measured wind pressure field on the surfaces of the models were analyzed, including mean wind pressure, fluctuating wind pressure, peak negative wind ...

OBJECTIVE The present study aimed to evaluate a new method for validation of complete linear block at the left atrial (LA) roof. BACKGROUND Linear lesions at the LA roof have been reported to improve the success rate of catheter ablation of atrial fibrillation (AF). METHODS Complete linear block at the LA roof was evaluated in 31 patients after complete isolation of pulmonary vein antrum (P...

This paper presents an approach to creating a polyhedral model of building roof from LiDAR point clouds using clustering techniques. A building point cloud is first separated into planar and breakline sections using the eigenvalues of the covariance matrix in a small neighbourhood. The planar components from the point cloud are then grouped into small patches containing 6-8 points and their nor...

In times of higher market prices of fossil fuels and to meet the increasingly environmental and economic threads of climate change renewable energy must play a major role for global energy supply. This paper focuses on a new method for fully automated solar potential assessment of roof planes from airborne LiDAR data and uses the full 3D information for both, roof plane detection and solar pote...

BACKGROUND Debate exists on the proper relation of the anterior cruciate ligament (ACL) footprint with the intercondylar notch in anatomic ACL reconstructions. Patient-specific graft placement based on the inclination of the intercondylar roof has been proposed. The relationship between the intercondylar roof and native ACL footprint on the tibia has not previously been quantified. HYPOTHESIS...
