Metapelitic rocks in the Gasht area include micaschist, kyanite schist, andalusite schist, garnet schist, staurolite schist, cordierite schist and sillimanite schist. Tourmaline occurs as accessory mineral in all of these rock types. These schists are metamorphosed regionally and are affected by contact metamorpism subsequently. Based on the textural relations and the fact that CaO and TiO2 con...

This study aims to present a novel approach for determining the weights of decision makers (DMs) based on rough group decision in multiple attribute group decision-making (MAGDM) problems. First, we construct a rough group decision matrix from all DMs' decision matrixes on the basis of rough set theory. After that, we derive a positive ideal solution (PIS) founded on the average matrix of rough...

lation is created of randomly transformed copies of the original DFG. A fitness is allocated to each member of the population. This is determined by calculating the supply voltage and effective capacitance of the DFG. Area requirements are computed for the adders, delays and multipliers. The total required area is used to estimate the effective capacitance. The GA selects a member of the popula...

Multicast Open Shortest Path First (MOSPF) is an en hancement to unicast routing protocol OSPF. It has been widely used in many multicast applications for years. How ever, its security is still a major concern in some applica tions. Much work has been done on data protection, but only a few works have been done on member access con trol mechanisms. In this paper, we present a new secure multica...

curve flexibility in adolescent idiopathic scoliosis (ais) was one of the major concerns of spinal surgeons since the evolution of surgical correction techniques. in this respect, many tried to identify which criteria denote more rigid curve. in the present study, we aimed toward determining important factors influencing ais curve flexibility on supine bending films. we assessed radiographs of ...

Factor analysis, like any other research tool, if it is to give meaningful results must be applied in an appropriate manner. A subtle yet recognised distortion of simplest factor structure is achieved by factoring a correlation matrix holding spurious correlations. Experimental dependence is most easily observed in an inter-correlation matrix when the total score of two or more variables in the...

For a square (0, 1,−1) sign pattern matrix S, denote the qualitative class of S by Q(S). In this paper, we investigate the relationship between sign patterns and matrices that diagonalise an irreducible nonnegative matrix. We explicitly describe the sign patterns S such that every matrix in Q(S) diagonalises some irreducible nonnegative matrix. Further, we characterise the sign patterns S such ...

the goal of this study was to assess attitude towards plagiarism in faculty members of medical school at tehran university of medical sciences. one hundred and twenty medical faculty members of tehran university of medical sciences were enrolled in this cross-sectional study. they were asked to answer to valid and reliable persian version of attitude towards plagiarism questionnaire. attitude t...
