Position Information From Reflecting Surfaces

Biological motion perception from sequential position information

Introduction Both in generating human activity and in the visual perception of it, the brain is confronted with the many degrees of freedom involved in the movement of body and limbs. Not unlikely, the perception of motor actions is supported by mechanisms that are very similar to those in control of these actions. Hints towards an interaction between perceptual and action processes can be foun...

Reflecting business process variability in information systems

Information systems are a fundamental support for the business processes of a firm. Information systems should be shaped on the needs of the business process throughout the life of the firm. This poses the problem of tracking changes in the business process and to reflect those changes in the information system. Assumptions and constraints are necessary in any real software project but can impa...

Analysis of Global Warming Mitigation by White Reflecting Surfaces

Theoretical and Computational Aspects of Scattering from Periodic Surfaces: Two-dimensional Perfectly Reflecting Surfaces Using the Spectral-Coordinate Method

We consider the scattering from a two-dimensional periodic surface. From our previous work on scattering from one-dimensional surfaces (Waves in RandomMedia 8, 385(1998)) we have learned that the spectral-coordinate (SC) method was the fastest method we have available. Most computational studies of scattering from two-dimensional surfaces require a large memory and a long calculation time unles...

Free energy surfaces from single-distance information.

We propose a network-based method for determining basins and barriers of complex free energy surfaces (e.g., the protein folding landscape) from the time series of a single intramolecular distance. First, a network of transitions is constructed by clustering the points of the time series according to the short-time distribution of the signal. The transition network, which reflects the short-tim...
