background: detection of best predictor of ovarian reserve in patients with temporarily or consistently elevated early follicular phase serum levels of fsh is one of the most important goals in assisted reproductive technique (art). objective: to evaluate whether high level of anti-mullerian hormone level is related to success of art in patients with temporarily or consistently elevated early f...

original article   change in the form of doing the task in some occupations such as farming has led to overweight and obesity as a threatening factor for farmer's health. this study aimed to compare the anthropometric indices of obesity and fatness as the predictors of cardiometabolic disorders among rural farmers in the northern part of iran. this cross-sectional study was carried out in 2012 ...

background: low back pain is the most common cause of disability and absence from work among young and middle-aged people. as there is limited knowledge regarding this problem among iranian students, this study aimed to determine the prev­alence of low back pain and its ‘related socio­demographic factors among students of islamic azad university, tehran, iran.    materials and methods: two hu...

It is known that both H 2 and H optimization problems for dead-time systems are solved by controllers having the so-called modified Smith predictor (dead-time compensator) structure. This note shows that this is also true for the L1 control problem. More precisely, it is demonstrated that the use of the modified Smith predictor enables one to reduce the standard L1 problem for systems with a si...

From a spectral method combined with a predictor-corrector scheme, we numerically study the behavior in time of solutions of the three-dimensional generalized Kadomtsev-Petviashvili equations regularized using the BBM trick. The solution no longer blows up and the solitonic behavior is observed.

This paper proposes a new modified discrete Smith predictor control scheme for stable processes with dead time. The processes are assumed to be of stable first order with time delay, which are commonly used in process industry. The present scheme consists of two parts: predictive disturbance observer (PDOB) and Smith predictor structure. The PDOB scheme exhibits the property of DOB structure wh...

The design and implementation of Generalized Minimum Variance control laws for nonlinear multivariable systems that can include severe nonlinearities is considered. The quadratic cost index minimised involves dynamically weighted error and nonlinear control signal costing terms. The aim here is to show the controller obtained is simple to design and implement. The features of the control law ar...
