background: brucellosis as a zoonosis is still a public health problem in many countries such as iran. to perform preventive, control, and eradication policies about the disease, we need the exact epidemiologic information and patterns of brucellosis in the country. in this study, we investigated the epidemiological, clinical, and treatment aspects of diseases in patients who had a record in sh...

this paper presents a discrete-time robust control for electrically driven robot manipulators in the task space. a novel discrete-time model-free control law is proposed by employing an adaptive fuzzy estimator for the compensation of the uncertainty including model uncertainty, external disturbances and discretization error. parameters of the fuzzy estimator are adapted to minimize the estimat...

a new approach for pole placement of nonlinear systems using state feedback and fuzzy system is proposed. we use a new online fuzzy training method to identify and to obtain a fuzzy model for the unknown nonlinear system using only the system input and output. then, we linearized this identified model at each sampling time to have an approximate linear time varying system. in order to stabilize...

in the last two decades, there has been an increasing interest in structural engineering control methods. shape memory alloys and seismic isolation systems are examples of passive control systems that use of any one alone, effectively improve the seismic performance of the structure. characteristics such as large strain range without any residual deformation, high damping capacity, excellent re...

the aim of the present study was to explore the relationship between media literacy and social skills among citizens in isfahan. to this end, a descriptive-correlation methodology was employed. the population under study consisted of all citizens living in isfahan who were reported to be 1796967 persons in 2013. using cochran formula, 384 persons were selected by stratified sampling and were in...

in this paper a robust road departure avoidance system based on a closed-loop driver decision estimator (dde) is presented. the main idea is that of incorporating the driver intent in the control of the vehicle. the driver decision estimator computes the vehicle look ahead lateral position based on the driver input and uses this position to establish the risk of road departure. to induce a risk...
