The present paper describes a testing method for five-axis machining centers using three-dimensional circular interpolation movement equivalent to cone-frustum cutting. In the present paper, the test conditions, such as the half apex angle of cone-frustum and the sensitive directions of the ball bar device were investigated. In addition, the sensitivity coefficient of each axis was investigated...

The visibility of gratings improves with increasing stimulus area. This effect is usually interpreted as being due to physiological summation within the extent of the largest spatial filter and due to probability summation between the outputs of linear, independent filters beyond that range. It is generally assumed that this improvement is isotropic to the patch configuration. In contrast, the ...

We have obtained integral-field spectroscopic data, using the SAURON instrument, of the bar and starbursting circumnuclear region in the barred spiral galaxy M100. From our data we have derived kinematic maps of the mean velocity and velocity dispersion of the stars and the gas, which we present here. We have also produced maps of the total, [Oiii], and Hβ intensity. The gas velocity field show...

The bar properties (elastic modulus, density, Poisson’s ratio, and sound speed) necessary for exploiting impact tests were calibrated via two methods called the 1D method (which combines iterative dispersion correction with approximation) 3D resorts to simulation-based reverse engineering of strain profile in a circular bar). cross-verified one another maraging steel 19.1 mm diameter. This pape...

This study analyzes the free vibration, forced vibration, resonance, and stress wave propagation of orthotropic sandwich plates made of functionally graded materials (FGMs). Dynamic analyses are conducted using a mesh-free method based on first-order shear deformation theory and the shape functions constructed using moving least squares approximation. The sandwich plates are rested on a Pastern...

Two groups of linear gene constructs (gus and bar, and 1Ax1 and bar) lacking vector backbone sequences were independently transferred into the elite wheat (Triticum aestivum L.) variety EM12, and genetically stable transgenic plants with low copy number transgene integration were recovered. Co-transformation experiments were carried out in parallel using either circular whole plasmid(s) or line...

The first results of the observational program of the study of 2D-kinematics in double-barred galaxies are presented. We show that, for the main part of the sample, the inner bars do not affect the circumnu-clear stellar kinematics. Therefore, they are not dynamically decoupled structures. Various types of non-circular gas motion were found in many galaxies. The analysis of the ground-based and...

a new approach for analyzing cracked problems in 2d orthotropic materials using the well-known element free galerkin method and orthotropic enrichment functions is proposed. the element free galerkin method is a meshfree method which enables discontinuous problems to be modeled efficiently. in this study, element free galerkin is extrinsically enriched by the recently developed crack-tip orthot...

ABSTRACT Most secular effects produced by stellar bars strongly depend on the pattern speed. Unfortunately, it is also most difficult observational parameter to estimate. In this work, we measured bar speed of 97 Milky-Way analogue galaxies from MaNGA survey using Tremaine–Weinberg method. The sample was selected constraining mass and morphological type. We improve our measurements weighting th...
