An alternative iterative computational procedure is proposed for internal normal ball loads calculation in statically loaded single-row, angular-contact ball bearings, subjected to a known thrust load, which is applied in the inner ring at the geometric bearing center line. An accurate method for curvature radii at contacts with inner and outer raceways in the direction of the motion is used. N...

Comparative study of the recognition of nonsemantic geometrical figures by the human subjects and ART neural network was carried out. The results of computer simulation experiments with ART neural network showed well correspondence with the psychophysical data on the recognition of different complexity visual patterns: in both cases the patterns of medium complexity were recognized with the hig...

We consider the interaction of a nonlinear Schrödinger soliton with a spatially localized (point) defect in the medium through which it travels. Using numerical simulations, we find parameter regimes under which the soliton may be reflected, transmitted, or captured by the defect. We propose a mechanism of resonant energy transfer to a nonlinear standing wave mode supported by the defect. Exten...

This is a shallow book on deep matters, about which the author knows next to nothing. The concept of the book is appealing: a popular review of geometrical notions from Euclid to Einstein as background to contemporary string theory with comments on the related intellectual history and portraits of some principal figures: Descartes, Gauss, Riemann and Einstein. Unfortunately the author is indiff...

Many animation systems rely on key-frames or poses to produce animated sequences of figures we interpret as articulated, e. g. the skeleton of a character. The production of poses is a difficult problem which can be solved by using techniques such as forward and inverse kinematics. However, animators often find these techniques difficult to work with. The work, presented in this thesis, propose...

Sequence, expression and complementation studies of dSno Ex17B , dSno Ex4B and dSno 174 Since our initial paper on dSno [1], we sequenced the breakpoints associated with our excision alleles (Figure S1). Sequencing revealed that dSno Ex17B is a deletion of 5023bp when compared to the parental dSno sh1402 allele or 11940bp when compared to the D. melanogaster chromosome arm 2L reference sequence...
