background: nowadays, the health work decision makers need to analyze a huge amount of data and consider many conflicting evaluation criteria and sub-criteria. therefore, an ergonomic evaluation in the work environment in order to the control occupational disorders is considered as the multi criteria decision making (mcdm) problem. in this study, the ergonomic risks factors, which may influence...

in this study the operations of melting of au15ag40 nanoalloy have been studied using the molecular dynamic simulations through the gupta multiparticle potential and the nonergodicity of simulations is eliminated by the multiple histogram method. the melting characteristics are determined by the analysis of variations in the potential energy. the calculations indicate that the melting of au15ag...

the purpose of this letter is to revisit the nonlinear reaction-diusion modelin porous catalysts when reaction term is fractional function of the concen-tration distribution of the reactant. this model, which originates also in uidand solute transport in soft tissues and microvessels, has been recently givenanalytical solution in terms of taylors series for dierent family of reactionterms. we...

it is well known that if the coefficient matrix in a linear system is large and sparse or sometimes not readily available, then iterative solvers may become the only choice. the block solvers are an attractive class of iterative solvers for solving linear systems with multiple right-hand sides. in general, the block solvers are more suitable for dense systems with preconditioner. in this paper,...

in this paper, we present two new families of third-order and fourth-order methods for finding multiple roots of nonlinear equations. each of them requires one evaluation of the function and two of its first derivative per iteration. several numerical examples are given to illustrate the performance of the presented methods.

the recent years have witnessed an increasing attention to the methods of multiple attribute decision making in solving the problems of the real world due to their shorter time of calculation and easy application. one of these methods is the ‘permutation method’ which has a strong logic in connection with ranking issues, but when the number of alternatives increases, solving problems through th...

Whether you're assessing risk, focusing on prevention, or treating an ulcer, this update--and handy treatment mnemonic--will help you optimize your care.

During communication we combine auditory and visual information. Neurophysiological research in nonhuman primates has shown that single neurons in ventrolateral prefrontal cortex (VLPFC) exhibit multisensory responses to faces and vocalizations presented simultaneously. However, whether VLPFC is also involved in maintaining those communication stimuli in working memory or combining stored infor...

Smart urbanism is shaping the world’s cities. Through use of digital sensors attached to urban infrastructure, smart cities data make quantitatively informed decisions regarding city management and policy. Yet, whilst elements exist in empirically observable realm, proposed benefits emerge from an unobservable reality. Therefore, forces driving are essentially invisible those who live within it...
