Abstract: When linearly polarized light impinging on a lens, it will reflect and refract along the lines curves resulting from the interception of a plane (plane of polarization) with a sphere (lens surface) maintaining the orientation of refraction and reflection within the plane of polarization. This effect is significant [...] Read more.

Abstract: In this paper, it is shown that the Magnus effect cannot be a primary mechanism for the dispersion of shotgun pellets. The one-dimensional motion of objects through air, applied to shotgun pellets traveling a short distance, reveals that throughout the flight, the Reynold’s number is approximately constant. The distribution [...] Read more.

Abstract: Assuming that time is determined by a present frequency, relations are derived based on the angular velocity of a noncircular orbit. Formats relating concepts of noncircular orbits with fix points of the sine circular map, so-called Arnold’s tongues, will be obtained. [...] Read more.

Abstract: In this paper, a compact microstrip low-pass filter (LPF) for radar applications is proposed. The microstrip filter configuration consists of a transmission line with a pair of S-shaped stub with radial stub loaded resonators (RSLRs), and a ground plane with triple array modified stairwell defected ground structures (DGSs). [...] Read more.

Abstract: The least action principle is the basic principle of the Newtonian mechanics and geometrical optics. Various forms of analytical mechanics are based on the principle of least action., including Lagrange mechanics, Hamiltonian mechanics and Hertz mechanics based on the principle of minimum curvature. Max Planck believed that [...] Read more.

Abstract: In this study, an effective technique upon compactly supported semi orthogonal cubic B-spline wavelets for solving nonlinear Volterra-Fredholm integral equations is proposed. Properties of B-spline wavelets and function approximation by them are first presented and the exponential convergence rate of the approximation, Ο(2- [...] Read more.

Abstract: The research of plastic deformation of metals attaches great importance to stacking fault energy (SFE). In this paper, we derive the expressions of four types (I1, I2, E and T2) of basal plane SFEs of hcp-Ti within the framework of the Ising model. Based on this model, alloying effects on the stacking fault energy (SFE) of [...] Read more.

Abstract: The concept of the coherence length of the neutron is explored. The generally accepteddefinition of a Gaussian wave packet based on the method of the beam preparation, andthe singular de Broglie's wave packet are considered. Possible ways of measuring thecoherence length are discussed. [...] Read more.

Abstract: Propagation and static distribution of light on noncircular orbits are modelled. The space where light embodies is determined with kinematics, such that the perpendicular velocity of the 'material'-space described as a noncircular orbit, is harmonic with amplitude fwre. Light propagation to discrete orbits may occur with a [...] Read more.

Abstract: The experimentally found small heating of the neutrons after transmission through thin foils can be explained by violation of energy conservation because of finite energy width of the neutron wave packet. The part of the wave packet subcritically transmitted through a foil has energy distribution higher than that of the inc [...] Read more.

Abstract: This article is devoted to the problem of light propagation in a space-time which curvature is due not to massive sources but to the electromagnetic field of the wave itself. Some methodological questions are discussed, such as an isotropy of metric, implementation of the Kalutza-Klein model, topology of space-time, etc [...] Read more.
