Tool wear state classification has good potential to play a critical role in ensuring the dimensional accuracy of the work piece and prevention of damage to cutting tool in machining process. During machining process, tool wear is an important factor which contributes to the variation of spindle motor current, speed, feed and depth of cut. In the present(More)
An attempt was made to develop a computational model based on artificial neural network and ant colony optimization to estimate the composition of medium components for maximizing the productivity of Penicillin G Acylase (PGA) enzyme from Escherichia coli DH5α strain harboring the plasmid pPROPAC. As a first step, an artificial neural network (ANN) model(More)
Orthogonal Frequency Division Multiplexing (OFDM) is an multicarrier modulation Format that can be easily adopted by different telecommunication standards such as LTE, LTE-A, Wi-Fi & WiMAX etc, now getting used in optical fiber communication. Chromatic dispersion arises due to Inter Symbol Interference (ISI) and it is serious issue in long-distance(More)
The present study involved the in vivo evaluation of orally administered guar gum-based colon-targeted tablet formulations of celecoxib (colon-targeted tablet-20 or colon-targeted tablet-30) as compared with an immediate release capsule in 15 human volunteers. Blood samples were obtained at different time intervals and the plasma concentration of celecoxib(More)
Many of the industrial processes are difficult to model because of their complex behavior, influent characteristics and operational conditions. Control of robot manipulator for industrial applications is considered as one of the challenging tasks. In this paper, Model Predictive Controller (MPC), a class of advanced control technique is proposed in order to(More)
