This paper describes an indirect level measurement for slag in the refinement process of liquid steel. Slag and slag foam can pollute plants and therefore lead to high costs due to cleaning and maintenance work. Knowledge of the slag level during production could help to prevent this by taking counter-measures at an early stage. We present a measurement strategy which is based on the radiated heat...
A combination of synchrotron X-ray and neutron diffraction have been used to characterise the sub-monolayer (low-coverage) crystalline structure of dodecanamide [CH3-(CH2)10-CONH2] adsorbed on graphite. The calculated structure reveals that the molecules lie flat on the graphite surface. The amide head-groups hydrogen-bond into dimers, and, significantly, adjacent dimers form further hydrogen bonds...
Sex robots are gaining a remarkable amount of attention in current discussions about technology and the future of human relationships. To help understand what kinds of relationships people will have with these robots, empirical data about people's views of sex robots is needed. We report the results of the first systematic survey that asks about the appropriateness and value of sex robots, acceptable...
Video endoscopy systems give physicians the ability to inspect internal structures of the human body by using a camera with attached endoscope optics. This technology has become a routine in clinics all over the world. Moreover, video endoscopy systems recently performed a technological change from PAL/NTSC image resolution to HDTV. There is a vast of literature on in-vivo and in-vitro experiments...
This paper presents an airborne multi-spectral imaging sensor which is able to simultaneously capture three visible and three near infrared channels. The first prototype was integrated in a Schiebel CAMCOPTER® S-100 VTOL (Vertical Take-Off and Landing) UAV (Unmanned Aerial Vehicle) for inflight tests. A low cost version of the initial multi-spectral imaging system was developed to fit into a more...
Terahertz time-domain spectroscopy can be used to characterize silicon solar cell properties such as: conductivity, charge carrier mobility and density. Moreover, THz spectroscopy and imaging can be used for defect analysis in semiconductor and photovoltaic materials. This paper describes the investigation of optically injected charge carrier dynamics by the use of THz spectroscopy. THz-pump/THz-probe...
Accurate and up-to-date soil monitoring allow farmers to take rapid, targeted action in case of nutrient deficiencies and pest infestation. This is essential for the maximization of crop-yields. This paper describes an airborne multi-spectral imaging system which is able to simultaneously capture three visible and two near infrared channels. The system was integrated in a Schiebel CAMCOPTER®...
Modern video endoscopy systems give physicians the ability to inspect internal structures of the human body by using a camera with attached endoscope optics. Video endoscopy has become routine in clinics all over the world. Moreover, video endoscopy systems recently performed a technological change from PAL/NTS C image resolution to HDTV. There is a vast amount of literature on in-vivo and in-vitro...
Ultrasonic strain and blood flow imaging have great potential to improve early tumor detection. Both methods share the same task of estimating echo signal displacements. To be able to resolve tissue stiffness and vascularity of tumors while still small in size, spatial resolution must be improved. In clinical practice ultrasonic real-time imaging is vital. In this paper we evaluate the performance...
