The camera stabilizer stabilizes the camera’s line of sight by isolating the camera from the model uncertainties, disturbances of operating environment and system movements. This paper presents a voltage-base optimal adaptive fuzzy sliding mode control for camera stabilizer. In this proposed control method, a voltage-base sliding mode controller is applied. But unfortunately, undesirable ...

abstract prediction of input flow into water resources is regarded as one of the most important issues in optimum planning and management in producing electro-water energy and optimum allocation of water into different consumption sources. different parameters affect on input discharge into dams. climate variables including temperature and rainfall have the most effect on input runoff rate to w...

risk-based assessment methods are commonly used at the contaminated sites by hydrocarbon pollutants. this paper presents the results of a two-dimensional finite volume model of reactive transport of biodegradable btex which have been developed for the saturated zone of an unconfined aquifer in the pump station area of tehran oil refinery, iran. the model governing equations were numerically sol...

the objective of this paper is to develop an artificial neural network (ann) model which can beused to predict temperature rise due to climate change in regional scale. in the present work data recorded overyears 1985-2008 have been used at training and testing steps for ann model. the multilayer perceptron(mlp) network architecture is used for this purpose. three applied optimization methods a...

energy method of evaluation is widely employed in analyzing problems associated with sustainable agriculture. in this study, energy ratio (er) of dryland wheat for three regions of eghlid township was quantified. the total cropping area of eghlid is nearly 8282 hectares comprised of: khosrowshirin (5000 ha), sedeh (1682 ha) and dezhkord (1600 ha). the corresponding values of wheat yield in thes...

In the current study the influence of weight percentage of HIPS, weight percentage of CNT and hardener content on damping 1st and damping 2nd properties of epoxy/HIPS/CNT hybrid composite wase valuated. Mixture design methodology was employed to generate mathematical models for predicting damping 1st and damping 2nd behaviors of new mentioned hybrid nanocomposite as function of physical factors...

evaporation is one of the main parameters for the optimum operation of reservoirs, design of irrigation systems and scientific management of water resources. accurate estimation of the water evaporation level is crucial in any region especially in arid and semiarid regions. in this study, the feasibility of simulation of pan evaporation in maraghe station using the multiple regression models we...
