With nonlinearity, large lag and time-varying model parameters of cement rotary kiln, this paper proposed a burning zone temperature control system of cement rotary kiln based on CMAC neural network. By Dynamic adjustment of PID controller parameters with CMAC neural network, combined with rotary kiln temperature control mechanism, the temperature controller based on CMAC-PID was designed. Then...

objective: the aim of this study was to evaluate and compare the cleaning ability and instrumentation time of manual and rotary methods used for preparation of primary anterior teeth. materials and methods: forty-four primary anterior teeth were used in this experimental study. access cavities were prepared and india ink was injected into the canals. the samples were divided into three groups a...

Rotary encoders for rotational angle detection have been used in a variety of industrial applications, including detection of actuation and travel amounts and motor speed control. In automotive applications, rotary encoders are utilized for steering system angle detection, accelerator pedals and throttle valves to improve vehicle operability and safety. For every automotive application, the nee...

introduction: the purpose of this study was to evaluate the efficacy of three methods in removal of resilon/new epiphany self-etch (se) soft resin endodontic obturation system. materials and methods: thirty extracted single rooted human teeth were prepared for endodontic treatment and obturated with resilon/epiphany se. the roots were randomly divided into three groups; group 1 roots were retre...

The output signals of the rotary incremental encoder are used for motion sense discrimination, angular displacement and rotational speed measurement of the encoder shaft. The angular displacement can be measured with different resolutions. This paper presents an experimental system that enables the study of the rotary incremental encoder: working modes and methods for resolution improvement, di...
