In reflection seismology one places sources and receivers on the Earth’s surface. The source generates elastic waves in the subsurface, that are reflected where the medium properties, stiffness and density, vary discontinuously. In the field, often, there are obstructions to collect seismic data for all source-receiver pairs desirable or needed for data processing and application of inverse sca...

In this study, super high-definition immersive visual data mining environment using 4K stereo projector was developed. In this system, data can be represented with high accuracy in the three-dimensional space using the super high-definition stereo images, and the user can recognize the relation among several kinds of data by integrating them in the immersive environment using the plug-in functi...

This paper describes a kind of active camouflage system named Optical Camouflage. Optical Camouflage uses the Retro-reflective Projection Technology, a projection-based augmented–reality system composed of a projector with a small iris and a retroreflective screen. The object that needs to be made transparent is painted or covered with retroreflective material. Then a projector projects the bac...

A brief introduction to the projector augmented wave method is given and recent developments are reviewed. The projector augmented wave method is an all-electron method for efficient ab-initio molecular dynamics simulations with full wave functions. It extends and combines the traditions of existing augmented wave methods and the pseudopotential approach. Without sacrificing efficiency, the PAW...

The supremum over all knot sequences of the max-norm of the orthogonal spline projector is studied with respect to the order k of the splines and their smoothness. It is first bounded from below in terms of the max-norm of the orthogonal projector onto a space of incomplete polynomials. Then, for continuous and for differentiable splines, its order of growth is shown to be √ k.

We give a functional analytic construction of the fermionic projector on a globally hyperbolic Lorentzian manifold of finite lifetime. The integral kernel of the fermionic projector is represented by a two-point distribution on the manifold. By introducing an ultraviolet regularization, we get to the framework of causal fermion systems. The connection to the “negative-energy solutions” of the D...

Iterative reconstructions for clinical PET must run fast. We describe a clinical processing method based on sinogram rebinning, Fourier rebinning for the 3D to 2D data reduction, and iterative reconstruction using the attenuation-weighted OSEM method with a projector based on a gaussian pixel model. When this approach is used, multi-bed clinical oncology scans can be ready for diagnosis within ...

Movie films are often damaged through ageing, chemical changes and contact with mechanical parts of the film projector. In this paper methods for the detection and removal of vertical scratches in digitised film sequences are discussed. This specific type of scratch arises by the contact of the film material running against a mechanical part of the camera or film projector. The proposed techniq...
