Fast Semantic Segmentation of 3D Point Clouds with Strongly Varying Density
(2016)ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information SciencesWe describe an effective and efficient method for point-wise semantic classification of 3D point clouds. The method can handle unstructured and inhomogeneous point clouds such as those derived from static terrestrial LiDAR or photogammetric reconstruction; and it is computationally efficient, making it possible to process point clouds with many millions of points in a matter of minutes. The key issue, both to cope with strong variations ...Conference Paper -
A Kinematic Process Model and Investigation of Surface Roughness for High Efficiency Dry Grinding
(2016)Procedia CIRP ~ 7th HPC 2016 – CIRP Conference on High Performance CuttingA grinding process model based on a kinematic modeling approach is presented. A unique experimental set-up is designed for validation purposes allowing table feed rates of up to 480 m/min. Modeling and experimental verifications are carried out under dry grinding conditions. Separating active and non-active grains during grinding can be controlled by depth of cut. Four basic grain types, such as cuboids, triangle prisms, triangular pyramid ...Conference Paper -
Building Blocks for Volume-oriented Changeability of Assets in Production Plants
(2016)Procedia CIRP ~ Research and Innovation in Manufacturing: Key Enabling Technologies for the Factories of the Future - Proceedings of the 48th CIRP Conference on Manufacturing SystemsDemand volatility and uncertainty in the business environment lead to an increasing relevance of volume-oriented changeability (VoC) for manufacturing companies. Strategic investment decisions are often based on forecasts and predictions, which more frequently fail to materialize due to obsolete assumptions or unpredictable events with extreme impact. If the production output fluctuates, fixed costs of production plants emerging from these ...Conference Paper -
Generation and spatial propagation of landslide generated impulse waves
(2016)Coastal Engineering Proceedings ~ Proceedings of 35th Conference on Coastal Engineering, Antalya, Turkey, 2016Large subaerial mass wasting into water may generate large waves along coast lines and in bays. Hazard assessment of such an events is based on the decay rate of these impulse waves along their propagation path to populated areas and infrastructure along the shoreline. The spatial propagation processes of impulse waves generated by deformable slides was investigated in a wave basin. A videometric measurement approach allowed for a detailed ...Conference Paper -

Investigation of the Mechanical Behaviour of the Interface between Soil and Reinforcement, via Experimental and Numerical Modelling
(2016)Procedia Engineering ~ Advances in Transportation Geotechnics IIIThe purpose of this study is to investigate the interface properties between soil and reinforcement, via experimental and numerical modelling of reinforced slopes. In particular, several scale models were built and tested under enhanced gravity in the geotechnical drum centrifuge at ETH Zurich and corresponding prototype numerical models were analyzed via a finite element stress analysis code. Optical fibre sensors were attached on the ...Conference Paper -
Switch-matrix-based Monolithic CMOS Platform Featuring a Large Array of Carbon Nanotube Sensor Elements and a 96-channel Readout Circuitry
(2016)Procedia Engineering ~ Proceedings of the 30th anniversary Eurosensors Conference – Eurosensors 2016We present a monolithic CMOS biosensor system comprised of a switch-matrix-based array of carbon nanotube field-effect transistors (CNT-FETs) and an associated readout circuitry. The switch-matrix allows for flexible selection and simultaneous routing of 96 sensor elements to the readout channels. The resistances of the CNT-FETs were measured by applying a constant voltage and measuring the resulting current. Variation of the first-stag ...Conference Paper -
Novel Sensor Integration Approach for Blood Pressure Sensing in Ventricular Assist Devices
(2016)Procedia Engineering ~ Proceedings of the 30th anniversary Eurosensors Conference – Eurosensors 201An application-specific approach for sensor integration for continuous blood pressure sensing in ventricular assist devices (VAD) is introduced. The piezoresistive absolute pressure sensor is to be located within the VAD's inflow cannula's sidewall. This diaphragm is fabricated by suspending a Parylene-C coating, covering the entirety of the cannula's interior, over a preformed recess. The recess is later sealed from the outside of the ...Conference Paper -
32-Channel Integrated Electrical Impedance Sensors on a Multi-Functional Neural Microelectrode Array Platform
(2016)Procedia Engineering ~ Proceedings of the 30th anniversary Eurosensors Conference – Eurosensors 2016An integrated measurement platform was implemented to make in-vitro impedance measurements of neuronal cells on a multi-functional CMOS microelectrode array (MEA). This high-density array is made of 59’760 platinum microelectrodes with a pitch of 13.5μm. Impedance sensing can be performed through 32 electrodes in parallel, while the electrode sites can be arbitrarily chosen on the array. A wave generator was also integrated on chip to ...Conference Paper -
Semantic Segmentation of Aerial Images with an Ensemble of CNNS
(2016)ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information SciencesThis paper describes a deep learning approach to semantic segmentation of very high resolution (aerial) images. Deep neural architectures hold the promise of end-to-end learning from raw images, making heuristic feature design obsolete. Over the last decade this idea has seen a revival, and in recent years deep convolutional neural networks (CNNs) have emerged as the method of choice for a range of image interpretation tasks like visual ...Conference Paper
