packaging is one of the most important parts of the food industry that is related to food security and it acts as a preserver that maintains the health of its content. product's packaging is the only mean of communication that absorb the attention of consumers in the store among other choices. the packaging is referred to as the silent salesman which means that it sells the product on retail sh...

Ambros (or Ambrosius) Mathias Rieder (1771‒1855) is perhaps one of the most underrepresented personalities music centre Vienna in late 18th and first half 19th century contemporary musicological music-theoretical discourse. Both his achievements as a composer field theory are remarkable. In particular, to be valued appreciated preserver tradition prelude playing, which became increasingly less ...

in this paper, we use a combination of legendre and block-pulse functionson the interval [0; 1] to solve the nonlinear integral equation of the second kind.the nonlinear part of the integral equation is approximated by hybrid legen-dre block-pulse functions, and the nonlinear integral equation is reduced to asystem of nonlinear equations. we give some numerical examples. to showapplicability of...

in this study, thermo-mechanical nonlinear vibration of a polyethylene (pe) cylindrical shell embedded in an elastic foundation was investigated. the shell is reinforced by armchair carbon nanotubes (cnts) where characteristics of the equivalent composite being determined using mori-tanaka model. the elastic medium is simulated using the spring constant of the winkler-type,  . employing nonline...

in many manufacturing processes, the quality of a product is characterized by a non-linear relationship between a dependent variable and one or more independent variables. using nonlinear regression for monitoring nonlinear profiles have been proposed in the literature of profile monitoring which is faced with two problems 1) the distribution of regression coefficients in small samples is unkno...

we consider an approximation scheme using haar wavelets for solving a class of infinite horizon optimal control problems (ocp's) of nonlinear interconnected large-scale dynamic systems. a computational method based on haar wavelets in the time-domain is proposed for solving the optimal control problem. haar wavelets integral operational matrix and direct collocation method are utilized to ...

Mobile genetic elements play a major role in shaping biotic genomes and bringing about evolutionary transformations. Herein, a new class of mobile genetic elements is proposed in the form of circulating nucleic acids (CNAs) derived from the billions of cells that die in the body every day due to normal physiology and that act intra-corporeally. A recent study shows that CNAs can freely enter in...

Cet article traite de l’estimation spectrale locale à partir de signaux radio-fréquence obtenus en imagerie medicale par échographie ultrasonore. Du fait de la nature particulière des signaux RF (signaux aléatoires fortement bruités et nonstationnaires et présence de plusieurs milieux tissulaires), l’objectif principal est de régulariser l’estimation paramétrique locale tout en préservant d’éve...

degenerate kernel approximation method is generalized to solve hammerstein system of fredholm integral equations of the second kind. this method approximates the system of integral equations by constructing degenerate kernel approximations and then the problem is reduced to the solution of a system of algebraic equations. convergence analysis is investigated and on some test problems, the propo...

the purpose of this paper is to studying nonlinear k-ε turbulence models and its advantages in internal combustion engines, since the standard k-ε model is incapable of representing the anisotropy of turbulence intensities and fails to express the reynolds stresses adequately in rotating flows. therefore, this model is not only incapable of expressing the anisotropy of turbulence in an engine c...
