The prediction of transdermal absorption for arbitrary penetrant structures has several important applications in the pharmaceutical industry. We propose a new data-driven, predictive model for skin permeability coefficients k p based on an ensemble model using k-nearest-neighbor models and ridge regression. The model was trained and validated with a newly assembled data set containing experimental data and structures for 110 compounds. On the basis of three purely computational descriptors (molecular weight, calculated octanol/water partition coefficient, and solvation free energy), we have developed a model allowing for the reliable, purely computational prediction of skin permeability coefficients. The model is both accurate and robust, as we showed in an extensive validation (correlation coefficient for leave-one-out cross validation: Q = 0.948, mean standard error: 0.2 for log kp). © 2006 American Chemical Society.

A three-dimension camera (Axi-Vision camera) has been developed that is capable of producing a color image of an object and performing high-speed mapping of depth information from the camera to the object. With this camera, intensity-modulated near-infrared light is irradiated onto the object, and distances to points on the object are computed from the image captured by a camera that has a high-speed shutter. Since a two-dimensional scanning mechanism for a laser beam or complex computational processing is unnecessary in this depth mapping system, the distance to the object can be detected at high speed for each pixel of a TV image. For the present paper, a three-dimension camera adapted to a standard television signal was constructed by development of a high-output light-emitting-diode (LED) array light source capable of high-speed intensity modulation, an image intensifier capable of high-speed shutter operation on the nanosecond order, and an optical system. The prototype camera can output a depth image with a resolution of 768 × 493 pixels at a frame rate of 15 Hz, the characteristic depth mapping resolution of the camera is 1.8 cm (when the distance from the camera to the object is 2 m), and the camera can capture an image of a person-sized object. It was also shown that the depth information thus obtained could be applied to live-action filming and to CG and other new types of image synthesis. © 2006 Wiley Periodicals, Inc.

YBa₂Cu₃O_7-δ thick films have been deposited onto Ag substrates by the Electrophoretic Deposition (EPD) technique. Different microstructures and electrical behaviours were observed depending on the starting powder. Coatings prepared from commercial powder displayed significant porosity and the superconducting transition width was found to be magnetic-field dependent. Films produced from home-made coprecipitated powder are denser but contain some secondary phases. No dependence of the resistive transition as a function of magnetic field (H 20 Oe) was observed in that case. © 2006 IOP Publishing Ltd.

A radical change (Feenstra, Holmer, Tromans, Moos and Mieritz 2003) in manufacturing is starting to occur. The Rapid Manufacturing, which can be defined as "the use of an additive manufacturing process to construct parts that are used directly as finished products or components", is set to supersede many current uses of moulds and dies. Rapid Manufacturing (Wohlers 2003) is based on new additive manufacturing techniques that produce fully functional parts directly from a 3D CAD model without the use of tooling. The ambitious scope of the European Initiative CUSTOM-FIT, a Framework 6 Integrated Project, is to create a fully integrated system for the design, production and supply of individualized custom-products. Within the cases under study there are strong connections to sporting articles. This project is being funded by the European Commission over the next four years and a half and will become central to European research concerning Rapid Manufacturing (RM).

The purpose of this paper is to demonstrate the design and implementation of GISolve - a Grid-based problem solving environment for computationally intensive geographic information analysis based on geo-middleware. The geo-middleware resides between existing Grid middleware and geographic information analysis applications to manage heterogeneous and dynamic resources on behalf of analysis applications. At the same time, GISolve provides adaptive domain decomposition solutions to parallel geographic information analysis applications. Based on these domain decomposition solutions, GISolve also schedules distributed tasks and manages data transfers. In GISolve, these capabilities are designed as Grid services that are compliant with the open Grid service architecture (OGSA) and are implemented using Grid portal technologies. The GISolve implementation is illustrated based on a case study of a computationally intensive spatial statistic - [Gi(d)] that is used to assess spatial dependence among geographically distributional observations. © 2005 IEEE.

An effective algorithm for automatic removal impulse noise from highly corrupted monochromatic images is proposed. The method consists of two steps. Outliers are first detected using local spatial relationships between image pixels. Then the detected noise pixels are replaced with the output of a rank-order filter over a local spatially connected area excluding the outliers, while noise-free pixels are left unaltered. Simulation results in test images show a superior performance of the proposed filtering algorithm comparing with conventional filters. The comparisons are made using mean square error, mean absolute error, and subjective human visual error criterion. © Springer-Verlag Berlin Heidelberg 2005.

A successive algorithm for Newton-Thiele's rational interpolation over rectangular grids is presented. A number of degenerate cases such as the univariate polynomial and rational interpolation problems are dealt with. The proposed successive interpolation algorithms can carry on the existing intermediate computations if new points are added to the grid. Numerical examples are given to show the effectiveness of our recursive algorithms.

2005 IEEE/RSJ International Conference on Intelligent Robots and Systems

A well-developed pose estimation scenario suitable for low altitude unmanned aerial vehicle (UAV) is proposed. By employing dual CCD cameras onboard, the instant pose of UAV can be determined without any use of expensive sensor like gyro. The unscented Kalman filter (UKF) is hereafter introduced to resolve the highly nonlinear system dynamics as well as the measurement process of the pose estimation system. The only measurements recorded are those snapshots of ground targets/landmarks taken by two CCD cameras. The proposed scenario can also detect large angle rotation of UAV. Simulation is conducted via a simple case, both UAV and ground targets are stationary, to show the feasibility and applicability of the proposed scheme. Actual GPS measurement data of ground targets coordinates was recorded for UKF processing. A highlight phenomenon, implied by simulation, reveals that a sudden transition of estimation errors arises at the epoch when the UAV is experiencing a large angle maneuvering up to 180/spl deg/ per second.

The advent of network coding promises to change many aspects of networking. Network coding moves away from the classical approach of networking, which treats networks as akin to physical transportation systems. We overview some of the main features of network coding that are most relevant to wireless networks. In particular, we discuss the fact that random distributed network coding is asymptotically optimal for wireless networks with and without packet erasures. These results are extremely general and allow packet loss correlation, such as may occur in fading wireless channels. The coded network lends itself, for multicast connections, to a cost optimization which not only outperforms traditional routing tree-based approaches, but also lends itself to a distributed implementation and to a dynamic implementation when changing conditions, such as mobility, arise. We illustrate the performance of such optimization methods for energy efficiency in wireless networks and propose some new directions for research in the area.

An arbitrary pattern exposure system has been developed by employing a liquid crystal display (LCD) with 1600 × 1200 pixels for the formation of projection images in place of a conventional reticle. The minimum pattern size becomes 11.5 μm, which corresponds to the aperture size of each pixel on the LCD. For the purpose of quick turnaround time (TAT), the exposure system was directly connected to the circuit design system with the transmission control protocol/internet protocol network. From the experimental results on patterning of a typical electronic circuit data with the area of 46 × 46 mm, it was confirmed that the TAT from the output of design data to the finish of the exposure becomes less than 28 min. By using this system, reduction of the production cost in the printed wiring boards fabrication is expected. © 2005 IEEE.
