2.3. Solution Assembly simulations and ergonomical studies are major fields for Virtual and Augmented Reality in industry. Both applications require direct object manipulation as the essential interaction method. Finger tracking is a tool, which allows to recognize finger positions without disturbing gloves and cables. Active markers allow to solve both the size and robustness problem: passive ...

this study was conducted to investigate the type and origin of clay minerals via several profiles in lordegan hilly lands. the profiles were located in two kinds of land uses including forest and dry farm at different slope positions as sampling sites. the soil saples were collected from two depths of soil horizons to indicate cec, soil texture, oc%, calcium carbonate equivalent, x-ray diffract...

Simplicial Nim, introduced by Ehrenborg and Steingŕımsson, is a generalization of the classical two-player game of Nim. The heaps are placed on the vertices of a simplicial complex and a player’s move may affect any number of piles provided that the corresponding vertices form a face of the complex. In this paper, we present properties of a complex that are equivalent to the P-positions (winnin...

Sentences in Dutch can be interrupted in various ways. We will use the term intercalation for interruptions by the speaker/writer that occur within the boundaries of a sentence without influencing this sentence (cf. de Groot 1949). The sentence (the host sentence or host) continues after the intercalation as if the intercalation were not there; the syntactic structure and the intonation pattern...

When deciding what to do agents must choose among alternative actions and different agents may make different choices according to what they wish to achieve in the light of their preferences and values. It cannot be assumed, however, that agents have a conscious understanding of their value preferences independent of the reasoning situations in which they engage. In this paper we consider an ex...

We develop methods for analyzing and constructing combined modulation/error-correctiong codes (ECC codes), in particular codes that employ some form of reversed concatenation and whose ECC decoding scheme requires easy access to soft information (e.g., turbo codes, low-density parity-check (LDPC) codes or parity codes). We expand on earlier work of Immink and Wijngaarden and also of Fan, in whi...

A method to find low energy paths in macromolecules is described. It can be applied either to determine paths between two given energy minimum conformations, or to explore low energy paths departing from one energy minimized conformation. The principle of the method consists in carrying out energy minimizations or molecular dynamics simulations with root mean square distance constraints with re...

Current ab initio structure-prediction methods are sometimes able to generate families of folds, one of which is native, but are unable to single out the native one due to imperfections in the folding potentials and an inability to conduct thorough explorations of the conformational space. To address this issue, here we describe a method for the detection of statistically significant folds from...

A single defocussed star image contains sufficient information to uniquely determine the spatial phase fluctuations of the incident wavefront. A sensor which responds to the intensity distribution in the image produces signals proportional to the wavefront curvature within the pupil and the radial slope at the pupil boundary. Unlike Roddier's differential curvature sensing technique, a single-i...
