TL;DR: In this article, the authors studied charge separation and trapping processes in N-doped TiO2 (N-TiO2) photocatalysts by means of time-resolved microwave conductivity (TRMC).
Abstract: We studied charge separation and trapping processes in N-doped TiO2 (N-TiO2) photocatalysts by means of time-resolved microwave conductivity (TRMC). We observed that the trapping rate increased wit...

TL;DR: In this article, the effect of implantation temperature on the mechanical property changes in sapphire caused by ion implantation was investigated, and the measured changes in surface hardness, surface fracture toughness and bulk flexural strength were largely correlated with the residual surface compressive stress measured by using a cantilever beam technique.
Abstract: Sapphire plates, cut parallel to an {0001} plane, have been implanted with 300 keV nickel ions to doses ranging from 5×1012 to 1×1017 Ni cm−2 at specimen temperatures of 100, 300 and 523 K, in order to investigate the effect of implantation temperature on the mechanical property changes in sapphire caused by ion implantation. The measured changes in surface hardness, surface fracture toughness and bulk flexural strength were found to depend strongly on the implantation temperature, and were largely correlated with the residual surface compressive stress measured by using a cantilever beam technique. The surface amorphization that occurred only by the implantation at 100 K and at doses larger than ∼2×10s15 Ni cm−2 reduced the hardness to ∼0.6 relative to the value of the unimplanted sapphire, and considerably increased the surface plasticity. Furthermore, the amorphization was found to involve a large volume expansion of ∼30% and to change drastically the apparent shape and size of a Knoop indentation flaw made prior to implantation. This effect was suggested to reduce stress concentrations at surface flaws and hence to increase the flexural strength.

22 Mar 2000TL;DR: In this paper, an Extended Kalman Filter is used for both the determination of motion and pose and for object recognition for a single camera in motion, where the optical flow parameters obtained from the photographed images are converted into physical parameters in three-dimensional space.
Abstract: Images are captured using a single camera in motion. A recognition process section detects a possible object in a photographed image, tracks the possible object within the moving image, and generates object shape information from the trajectory information. A motion and pose determination section determines camera motion and pose using the photographed images for recognition processing. The determined data are used for object recognition along with the tracking information. The motion and pose determination section converts the optical flow parameters obtained from the photographed images into physical parameters in three-dimensional space. An Extended Kalman Filter is used for both the determination of motion and pose and for object recognition.
