addressing the holly quran as “poem” and the prophet as “poet” was one of the accusations that pagans propounded to deny the divinity of the quran and the prophecy of the prophet. although there are different views on the meaning of “poetry” and “poems” in pagans’ language and two perspectives “structural dimension” and “dimension of fantastic content” have more advocates among commentators, ex...

Minimal dimension dynamic covers play an important role in solving the structural synthesis problems of minimum order functional observers or fault detectors, or in computing minimal order inverses or minimal degree solutions of rational equations. We propose numerically reliable algorithms to compute two basic types of minimal dimension dynamic covers for a linear system. The proposed approach...

Dimension reduction and variable selection play important roles in high dimensional data analysis. The sparse MAVE, a model-free variable selection method, is a nice combination of shrinkage estimation, Lasso, and an effective dimension reduction method,MAVE (minimum average variance estimation). However, it is not robust to outliers in the dependent variable because of the use of least-squares...

Nowadays healthy life style as a social dimension of health in academic world and making policy has considerable importance. Health promotion behaviors and conditions are beyond the limit impressible by structural factors and conditions. This research is conducted to examine influence of Socio-Demographic factors on daily sports activities among 15-34 years old youths in Iran urban areas by usi...

The modified bubble-sort graph of dimension n is the Cayley graph of Sn generated by n cyclically adjacent transpositions. In the present paper, it is shown that the automorphism group of the modified bubble sort graph of dimension n is Sn × D2n, for all n ≥ 5. Thus, a complete structural description of the automorphism group of the modified bubble-sort graph is obtained. A similar direct produ...

We examine categoricity issues for computable algebraic fields. Such fields behave nicely for computable dimension: we show that they cannot have finite computable dimension greater than 1. However, they behave less nicely with regard to relative computable categoricity: we give a structural criterion for relative computable categoricity of these fields, and use it to construct a field that is ...
