Density Functional Theory (DFT) calculations at the B3LYP/6-31+G∗ level have been performed on 5-thiabicyclo[2.1.1]hex-2-ene S-oxide derivatives. The geometrical and electronic properties of the compounds have been analyzed in order to explain the favored stability of the exo configuration. Isodesmic reactions at the Gaussian-G2 theory yielded the exo conformer as the most stable one. Moreover,...

The purpose of functional tolerancing process is to define the geometrical specifications of parts ensuring functional requirements. For automotive and aircraft industries, the tolerance synthesis has become an important issue in product design process. Indeed, designers need methods and rules to determine the tolerances. To define rules, a mathematical formulation of tolerance synthesis is det...

Most developmental studies consistently show that sensitivity to purely pictorial cues to perceptual organization emerges around 6-7 months of age (e.g. B. I. Bertenthal, J. J. Campos, & M. M. Haith, 1980). Here, we show evidence for an early emergence of visual completion using purely static two-dimensional pictorial information. By using preferential looking technique, we examined whether 3-4...

An explicit solution in super Yang-Mills theory, which after T-duality describes two sets of D4-branes at angles, is constructed. The gauge configuration possesses 3/16 unbroken supersymmetry, and can be considered as the counterpart of the solution of D = 11 supergravity with the same amount of supersymmetry in the solutions given by Gauntlett et al. The energy of the Born-Infeld action of the...

We developed the first Monte-Carlo code for threedimensional self-consistent continuum radiative transfer calculations. The density structure of the dust configuration (disk/envelope/molecular cloud core) can be chosen arbitrarily as well as the number, configuration, and radiation parameters of the stars inside this configuration. Binaries and multiple stellar systems (with or without disks ar...

We report a reconstruction method, called a back-projection filtered (BPF) algorithm, for fan beam differential phase contrast computed tomography (DPC-CT) with equidistant geometrical configuration. This work comprises a numerical study of the algorithm and its experimental verification with a three-grating interferometer and an x-ray tube source. The numerical simulation and experimental resu...

We present the study of the solar wind interaction with the super-Alfvénic magnetized interstellar medium in the controversial case when fast magnetosonic shocks are nonevolutionary, while admissible switch-on shocks cannot exist due to geometrical reasons. The flow behaviour and the accompanying shock configuration are investigated both in the twodimensional axisymmetric and 2.5-dimensional, t...
