controlling is a very important function of every manager. controlling is based and closely related to planning or the first function of management. these two functions are so related to each other that may be viewed as the blades of a pair of scissors. the scissors can not work unless there are two blades. without plans, control is not possible. theoretically, the concept of concept of control...

talented individuals, who are bleeding from the nose, usually do not go to the doctor, except in case of sever and unusual bleeding. because traditional method of treatment is not effective in nasopharanx bleeding, so malcolm harvey explain brighton epistaxis balloon as a new method  for controlling nasopharanx bleeding through the paper. epistaxia usually happen in the anterior part of the nas...

in this work, we report synthesis of silver nanoplates by a simple reduction process of silver nitrate in the presence of polyvinyl alcohol (pva) and n,n'-dimethyl formamide (dmf). the characterization of the samples were carried out using x-ray diffraction (xrd), transmission-electron microscopy (tem) and uv-vis spectroscopy. absorption spectra of the nanoplates in comparison with that of...

a sigmoid function is necessary for creation a chaotic neural network (cnn). in this paper, a new function for cnn is proposed that it can increase the speed of convergence. in the proposed method, we use a novel signal for controlling chaos. both the theory analysis and computer simulation results show that the performance of cnn can be improved remarkably by using our method. by means of this...
