in the present study, the mechanical behavior of aa5052 aluminum alloy during cold deformation and subsequent isothermal annealing in a temperature range of 225-300oc was investigated using the uniaxial tensile test data. it is found that by increasing the annealing time and temperature the material yield strength is decreased. the microstructural investigations of the annealed samples show tha...

The bosonic large-[Formula: see text] master field of the IIB matrix model can, in principle, give rise to an emergent classical spacetime. task is then calculate this as a solution master-field equation. We consider simplified version algebraic equation and take dimensionality [Formula: size text]. For explicit realization pseudorandom constants entering equation, we establish existence find, ...

We assume that each valence quark in a nucleon is in a phenomenological modified harmonic oscillator potential of the form: ( l+yo) (ar +br+cr +dr ), where a, b, c and d are constants and ? is one of the Dirac matrices. Then by making use of a suitable ansatz, the Dirac equation has a very simple solution which is exact. We then have calculated the static properties of the nucleon in the ...

in the present work, attempts have been made to find appropriate coating by testing different compounds. results showed that the optimum enamel is a compound with 1 wt.% cobalt oxide, 3 wt.% chromium oxide (in addition to hundred percent) with the firing temperature of 840 ˚c. constants of vft equation were determined by examination of melting behavior of the optimum enamel and measurement of t...

Remotely keyed encryption (RKE) schemes provide fast symmetric encryption and decryption using a small-bandwidth security module and a powerful host. Such schemes keep the key inside the security module to prevent key compromise. Shin, Shin, and Rhee proposed a length-preserving as well as a length-increasing RKE scheme that both use only a single round of interaction between host and security ...

Stimulated by a recent development of the universal seesaw mass matrix model, the evolutions of the gauge and Yukawa coupling constants are investigated under the gauge symmetries SU(3)c×SU(2)L×SU(2)R×U(1)Y . Especially, an investigation is made as to whether this evolution can constrain the necessary intermediate scales in these types of models and its viability. 12.15.Ff, 11.10.Hi, 12.60.-i T...

we investigate the exact renormalization group (RG) in Einstein gravity coupled to N-component scalar field, working in the effective average action formalism and background field method. The truncated evolution equation is obtained for the Newtonian and cosmological constants. We have shown that screening or antiscreening behaviour of the gravitational coupling depends cricially on the choice ...

The Feigenbaum constants arise in the theory of iteration of real functions. We calculate here to high precision the constants a and S associated with period-doubling bifurcations for maps with a single maximum of order z , for 2 < z < 12. Multiple-precision floating-point techniques are used to find a solution of Feigenbaum's functional equation, and hence the constants. 1. History Consider th...

In the present work, we improve a numerical method, developed to solve the Gross-Pitaevkii nonlinear Schrödinger equation. A particular scaling is used in the equation, which permits us to evaluate the wave-function normalization after the numerical solution. We have a two-point boundary value problem, where the second point is taken at infinity. The differential equation is solved using the sh...
