A series of experiments in recent years have shown that under carefully designed circumstances the group velocity, or even more surprisingly the energy velocity can exceed the speed of light in vacuum or become negative (abnormal velocities). These abnormal results have led some researchers to question the validity of special relativity, or at least cast doubt on the relevance of these principl...

the integration of an approximate model and a clonal selection algorithm (csa) is considered to one of the most effective ways to solve complex optimization design problems in engineering. in this study, first, a process for developing an approximate model and the principles of clonal selection algorithms were presented. then, a variotherm temperature injection mold used to produce a large liqu...

Acceptance sampling (AS), as one of the main fields of statistical quality control (SQC),involves a system of principles and methods to make decisions about accepting or rejecting alot or sample. For attributes, the design of a single AS plan generally requires determination ofsample size, and acceptance number. Numerous approaches have been developed foroptimally selection of design parameters...

In the recent twenty-year retrospective issue of Animal Behavior and Cognition, Povinelli Henley (2020) argue that a host comparative studies into “complex cognition” suffer, fatally, from theoretical confusion. To rectify problem, they following challenge: alongside specifications higher-order capacity to be tested, provide hypotheses mechanism(s) necessary implement it. They spearhead this ef...

this article aims at proving the prevalence of the surrealistic characteristics in zakariyya tamir`s first short story collection entitled sahil al-jawad al-abyad (the neighing of the white steed).although this contemporary syrian author was influenced directly by the works of the surrealist authors like sartre and camus and kafka, he managed to digest classical forms and customize western lite...
