Approximation of General Form for a Sequence of Linear Positive Operators Based on Four Parameters
Get PDFIn the present paper, we define a generalization sequence of linear positive operators based on four parameters which is reduce to many other sequences of summation–integral older type operators of any weight function (Bernstein, Baskakov, Szász or Beta). Firstly, we find a recurrence relation of the -th order moment and study the convergence theorem for this generalization sequence. Secondly, we give a Voronovaskaja-type asymptotic formula for simultaneous approximation. Finally, we introduce some numerical examples to view the effect of the four parameters of this sequence
The Universal Coefticient Theorem in the Category of Fuzzy Soft Modules
Get PDFThis paper begins with the basic concepts of chain comlexes of fuzzy soft modules. Later, we introduce short exact sequence of fuzzy soft modules and prove that split short exact sequence of fuzzy soft chain complex. Naturally, we want to investigate whether or not the universal coefficient theorems are satisfied in category of fuzzy soft chain complexes. However, in the proof of these theorems in the category of chain complexes, exact sequence of homology modules of chain complexes is used. Generally, sequence of fuzzy soft homology modules is not exact in fuzzy chain complexes. Therefore in this study, we construct exact sequence of fuzzy soft homology modules under some conditions. Universal coefficients theorem is proven by making use of this idea

Get PDFIn the present paper, we have studied the curvature tensors of almost C()-manifolds satisfying the conditions
P(,X)R = 0, P(,X) e Z = 0, P(,X)P = 0, P(,X)S = 0 and P(,X) e C = 0. According these cases, we classified almost C()-manifolds
Old Inconsistency in Electromagnetism and a Way to Eliminate It
Get PDFClassical electromagnetic theory uses axial pseudo-vectors to describe magnetic interactions. It is impossible to explain adequately magnetic interaction at the micro level (elements of conductors and the magnetic interactions of charges) by axial vectors. As a result, the correct form of interactions in classical electrodynamics is only an integral one. The differential formulas for magnetic interactions violate the third Newtons law. In the paper, we use polar vectors (real physical vectors) to describe magnetic interactions. On this way, we show that the real physical magnetic field, in contrast to the solenoidal field of the axial vector magnetic induction B, has two components: a potential field with nonvanishing divergence and a solenoidal field with vanishing divergence. These two fields act separately and independently and have different models of interactions. Doing so, we can write differential form for the Amperes law obtaining correct formula for the magnetic interactions and adequate interpretation of the Biot-Savart law
Newly Discovered Topological Insulator Sr3SnO for Spintronics, Optical and Electronic Properties
Get PDFA theoretical study of the electronic and optical properties of dilute magnetic semiconductor Sr3SnO is presented, using the full potential linearized augmented plane wave method. The Perdew Burke Ernzerhof (GGA08) (generalized gradient approximation) is used for the total energy calculations, while the Modified Becke Johnson (MBJ) is used for electronic structure calculations since this functional was designed to reproduce as well as possible the exact exchange correlation potential rather than the total energy, and as a result gives significantly improved results such as band gap and electronic structure. In this study, we have investigated the optical properties by means of first-principles density-functional total-energy calculation using the all-electron full potential linear augmented plane-wave method (FPLAPW)
Tensorial Computation of the intensity of UHF Electromagnetic Radiation within Geometrical Structures
Get PDFIn this paper, a tensorial method was used in computing the intensity of Ultra High Frequency(UHF) radiation within 2D and 3D geometrical structures. This was done based on the theoretical concepts of classical electromagnetism. Using a software program, “power estimator” the intensities at various distances from the source of radiation were obtained and it was found that shapes which are less geometrically homogenous exhibits high intensity values and that the maximum intensity value was observed within a cylinder to be 1534.70w/m² at 0.02m away from the source of radiation, while the minimum intensity value was observed in a circle at 0.10m away from the source to be 2.49w/m²
Entanglement Explained by Sequencing Satisfies Lack of Trajectory and The Holographic Principle
Get PDFThe implications of entanglement have scared many, but if we use all we understand about existence sequencing is probably the answer given probable experiments that we should have the technology to do within the next 5 years. The simpler the easier to understand. This paper is in the tradition of thought experiments, not all have access for modern technology, a thought of the mind, given that we are further introducing algorithms into not only physics but life in general, sequencing is merely an algorithm
