Abstract: An example embodiment of the present invention provides a method of assessing the condition of a pavement site, comprising: (a) acquiring aerial images of the site from above, for example by an unmanned aerial system (UAS); (b) using photogrammetry tools to generate an orthomosaic that represents the airport pavement surface; (c) using image analysis tools and machine learning methods to determine the location and extent of defects in the pavement; (c) producing an image representation of the site and the defects, where the location and extent of defects are discernible from the image; (d) using software application techniques to store and present defect data and other related information for client-side user access.

Abstract: A porous structure and a porous assembly resulted therefrom for implants allow a tissue to go through and attach for ingrowth, thereby achieving an ideal fixing effect. At least one porous structure is provided with a plurality of geometric-contoured apertures defined by walls. At least one channel is disposed on the apertures or the walls along a reference axis so that the adjoining apertures are intercommunicated, and the porous structures are connected and/or stacked with each other to contribute a porous assembly.

Abstract: A femoral head prosthesis assembly and operation instruments thereof. The operation instruments include a hollow femoral neck holder with a configuration adapted to the surface configuration of the femoral neck and a shaper blade for cutting a replacement end of the femur into a predetermined configuration. A guide tube is disposed on a top face of the femoral neck holder. A transverse slot is formed on the femoral neck holder for indicating a femoral head cutting line. The femoral head prosthesis assembly includes a cap body and an artificial femoral head. A root section of the cap body has an inner surface in conformity to the surface of the femoral neck. A top section of the cap body has a cross section adapted to that of the replacement end. The cap body can be precisely securely bonded with the replacement end of the femur.

Abstract: Diamond film with substantially no non-diamond carbon and a high thermal conductivity is deposited by means of a direct current arc jet apparatus with a substrate temperature below about 975 degrees Celsius, an arc power of between about 20 and 40 kw. A pressure of about 12 torr, and an enthalpy greater than 30 from a activated gas jet fed with hydrogen and methane, the methane being supplied at a concentration of less than 0.07%. The resulting material has a high transparency and thermal conductivity.Also disclosed is the use of the diamond material made by the present method for cutting tool applications, particularly milling.

Abstract: The process is an arc jet CVD diamond deposition process with very low methane, less than 0.07%, and the addition of water. The resulting material has is characterized by a narrow Raman peak, a relatively large lattice constant, and a charge carrier collection distance of at least 25 microns.
