In the field of fabric manufacturing, many factories still utilise traditional manual detection method. It requires a lot labour, resulting in high error rates and low efficiency. this paper, we represent realtime automated method based on object as point. This work makes three attributions. First, build defects database augment data to training intelligence model. Second, provide real-time alg...

Point defects play an important role in determining the structural stability and mechanical behavior of intermetallic compounds. To help quantitatively understand the point defect properties in these compounds, we developed PyDII, a Python program that performs thermodynamic calculations of equilibrium intrinsic point defect concentrations and extrinsic solute site preferences in intermetallics...

there are many different ways to subdivide the spectrum of a bounded linear operator; some of them aremotivated by applications to physics (in particular, quantum mechanics). in this study, the relationship betweenthe subdivisions of spectrum which are not required to be disjoint and goldberg's classification are given.moreover, these subdivisions for some summability methods are studied.

Objective- The present study was aimed to evaluate repair of a critical segmental defect of rabbit femur using the rabbit’s femoral defects repaired by Zeolite and Zeolite/Collagen scaffolds Design- Experimental Study Animals- Forty-five mature male New Zealand white rabbits Procedures- The animals were randomly divided into three groups of 15 animals each. In the first group...

Development of rechargeable batteries for electronic appliances requires advancement synthesizing new anode, cathode, and electrolyte materials. Li2GeO3 is a candidate anode material use in lithium ion owing to its fast Li-ion conductivity. Using advanced computational simulation techniques based on the classical potentials, we investigate defect, diffusion, dopant properties Li2GeO3. Our finds...

This study focuses on the mechanisms of pipe diffusion and kinetic point defect along dislocation line in MgO. We developed a numerical approach, based atomic scale calculations use elasticity theory, to determine migration energies defects. The is then evaluated according on-lattice atomistic Monte Carlo algorithm informed by simulations. show that edge MgO behaves as strong sink for vacancies...

A point defect based model is developed in two dimensions for the evolution of a group of dislocation loops induced by high dose ion implantation in silicon. Assuming an asymmetric triangular density distribution of periodically oriented circular dislocation loops provides an efficient model reflecting the nonuniform morphology of the loops as observed in transmission electron microscopy (TEM) ...

The solid state reaction of CUWO4-2 formation from CuO and WO3 was studied by the contact method in air and nitrogen. The results showed that the reaction is governed by the diffusion of the W 6 + and 0 2 _ ions and that the rate determining step is the diffusion of oxygen ions in the reaction product. This is in agreement with the defect structure of copper tungstate, an n-type semiconductor w...

The influence of anisotropic diffusion coefficients on diffusion-controlled high-temperature creep is examined. Anisotropic diffusion affects anisotropy of diffusion-controlled deformation of a single crystal. The shape change of a single crystal by diffusional mass flux is controlled directly by the anisotropy in diffusion coefficients. The rate of shape change of a single crystal by diffusion...
