Abstract: A system for improved localization of image forgery. The system generates a variational information bottleneck objective function and works with input image patches to implement an encoder-decoder architecture. The encoder-decoder architecture controls an information flow between the input image patches and a representation layer. The system utilizes information bottleneck to learn useful residual noise patterns and ignore semantic content present in each input image patch. The system trains a neural network to learn a representation indicative of a statistical fingerprint of a source camera model from each input image patch while excluding semantic content thereof. The system can determine a splicing manipulation localization by the trained neural network.

Abstract: A welding process involves a fixture for holding a workpiece and a welder, or welding electrode. The fixture imposes ultrasonic vibration on the workpiece. The welder vibrates during vibration, and is operable at a first voltage for elding and a second voltage for peening. The peening may occur while the weldmetal is crystallizing. The welding process may be a process of welding two part as together, or of filling a groove or other feature, or of applying or restoring a surface, or of applying a hard facing or ceramic to a parent metal or object. The weldmetal may be the same, or substantially the same, as the parent metal, or it may be different. The different material may be a ceramic material.

Abstract: A method and apparatus for the processing of surface coating is disclosed concerning the design of an ultrasonic pressurized rotating friction head assembly used to apply a surface coating to a workpiece. The shape of the friction head may be flat or curved as appropriate for the workpiece. The surface coating is rotated under repetaed contact and ultrasonic vibration. The apparatus includes: a work station for the mounting and rotation of a TiC coated welding electrode workpiece; a rotating friction head assembly with an ultrasonic transducer and power source. Concurrent application of pressurized rotating friction and ultrasonic vibration, may tend to reduce the defects in the TiC coatings on welding electrodes produced using the electro-spark deposition process. While maintaining the basic coating material component contents, mechanical and physical properties unaltered, defects such as delaminations, cracks, discontinuities and voids may be reduced.

Abstract: Methods of prolonging survival of allotransplanted cells, tissues or organs are presented. These methods are directed to administering to the allograft recipient an inhibitor of complement activity together with one or more immunosuppressants and/or immunosuppressive methods. The inhibitor of complement activity is administered chronically. These methods have been determined to aid in preventing chronic rejection of allografts. These methods can additionally be used in cases in which the recipient has been presensitized to the allograft or in which there is an ABO mismatch between the allograft and the recipient.
