Prediction of the production rate of the cutting dimensional stone process is crucial, especially when chain saw machines are used. The cutting dimensional rock process is generally a complex issue with numerous effective factors including variable and unreliable conditions of the rocks and cutting machines. The Group Method of Data Handling (GMDH) type of neural network and Radial Basis Functi...

An instance of the Viterbi algorithm has been applied to the cubic phase function and chirp-rate estimation. The proposed algorithm has shown excellent performance for high noise environment. The obtained chirprate estimate is used in the instantaneous frequency estimation. The proposed instantaneous frequency estimator gives superior performance with respect to the state-of-the-art techniques ...

Despite the population of the noninvasive, economic, comfortable, and easy-to-install photoplethysmography (PPG) sensor, a mathematically rigorous and stable algorithm to simultaneously extract the fundamental physiological information, including the instantaneous heart rate (IHR) and the instantaneous respiratory rate (IRR), from the single-channel PPG signal is lacking. A novel signal process...

Instantaneous friction and wear energy density are important indicators of the state tooth flank milling cutter. Existing methods for identifying on cutters mainly focus overall level consumption maximum width accumulated teeth flanks, ignoring unevenness variability volume distribution tool flank, dynamic relationship between instantaneous each cutter is to be revealed. Transient cutting posit...

In this research work the tool-chip interface temperature is measured experimentally during turning of EN-31 steel alloy with tungsten carbide inserts using a tool-work thermocouple technique. First and secondorder mathematical models are developed in terms of machining parameters by using the response surface methodology on the basis of the experimental results. The results are analyzed statis...
