background: currently, orofacial sequelae are recognized as very influential on the qualityof- life for a victim of orofacial damage. therefore, correct forensic assessment for indenisation purposes is mandatory. however, orofacial damage is frequently reduced to organic components, which results in a forensic assessment process, which are inadequate. this study aims to improve the orofacial da...

background: the area of contaminated lands exposed to the health risk of environmental pollutants is a matter of argument. in this study, a new method was developed to estimate the amount of area that is exposed to higher than normal levels of cr, mn, and v. methods: overall, 170 soil samples were collected from the upper 10 cm of soil in an arid area in central part of iran in semnan province....

background: extubation is associated with the risk of complications such as accumulated secretion above the endotracheal tube cuff, eventual atelectasia following a reduction in pulmonary volumes because of a lack of physiological positive end expiratory pressure, and intra-tracheal suction. in order to reduce these complications, and, based on basic physiological principles, a new practical ex...

in this paper, a new topology is proposed for three-phase to single-phase matrix converters, where more voltage levels are produced in the output in comparison with the conventional topologies. in addition, a new control method based on minimum error between the generated and the desired output voltages is proposed for three-phase to single-phase matrix converters. in the proposed control metho...

A map or, more generslly, a numerical model of an attribute’s dwhibution in spsce is rarely sn end goal. Maps are used as input to some transfer function designed to simulate a response of interest (Fig. 1). The “quslity” of a map m numericaf model should be appreciated in relation to the p2rticubu transfer function through which it will be processed. A map is a poor model of reality if it does...

 Background: The transfer of the tibialis posterior tendon to the dorsum of foot can restore the function of the paralyzed dorsiflexor muscles of the foot and ankle. In order to reduce the wound complication in the insertion site of tendon to bone by a plantar knop we used a new method of fixation by an absorbable screw inserted dorsally. Methods: we performed this operation on 15 patients in...

In this paper we propose a new method for ranking Z- numbers and generalizations. This method is based on the internal structure of the artificial neural network, which suggests that the structure of this network consists of inputs weights and the transfer function linear, nonlinear and sometimes linear and nonlinear. It is shown that the proposed method while possessing the ranking properties ...

Ranking fuzzy numbers plays a very important role in linguistic decision making and other fuzzy application systems. In spite of many ranking methods, no one can rank fuzzy numbers with human intuition consistently in all cases. Shortcoming are found in some of the convenient methods for ranking triangular fuzzy numbers such as the coefficient of variation (CV index), distance between fuzzy set...
