Now, the multiple solar spectrograph, with replica of grating Bausch & Lomb 128×154 mm, 600 lines/mm, blaze angle 17°27′, collimator 230 mm in diameter and 15 m in focal length, has been put into operating.
An improved visualization device made of polymethyl methacrylate (PMMA) was used to study the 3D flow profile inside conical columns of a 10° opening angle packed with C18 phase.
The Brill transition of even-even polyamide 618 was investigated using differential scanning calorimetry (DSC), temperature-dependent wide angle X-ray diffraction (WAXD) and Fourier transform infrared (FTIR).
The transmittance passing through the cell between crossed polarizers changed periodically with a regular 90° separation of the rotational angle.
The pretilt angle of the cell was found to be 2.8°.
With the increase of DHPDMS content, the water contact angle increased while the surface tension decreased.
By producing a L2 convergent Neumann series, we prove the invertibility of the elastostatics and hydrostatics boundary layer potentials on arbitrary Lipschitz domains with small Lipschitz character and 3D polyhedra with large dihedral angles.
The structure of the pigment was characterized by X-ray diffraction (XRD), and its optically variable effect was investigated by X-Rite MA86 II five angles spectrophotometer.
In NQGA, a novel approach for updating the rotation angles of quantum logic gates and a strategy for enhancing search capability and avoiding premature convergence are adopted.
The 2D/3D scattering center models can be reconstructed based on the wideband measurements at different viewing angles.
Research results show that initiation and propagation laws are the same with interior symmetric wedge angles of 30°-120°, while the laws are different with interior symmetric wedge angles equal to or more than ≥150°.
This wavelet basis is obtained from three wavelet generators by scaling, translation and rotation, and the wavelets are supported either by one corner triangle or a pair of adjacent triangles in the triangulation of level k - 1.
Localization of a Corner-Point Gibbs Phenomenon for Fourier Series in Two Dimensions
In this note we prove that the corner cutting procedure preserves continuity properties, i.e., a sequence of polygons obtained in this way belongs to the Lipschitz class of the same constant and exponent.
Using two micro-motors, a novel omni-direction miniature wheeled robot is designed on the basis of the bi-corner driving principle.
Coal is relatively thick in the northern part and the southeastern corner.
