An Experimental Study on the Effect of Temperature on Piezoelectric Sensors for Impedance-Based Structural Health Monitoring
(Sensors, 2014-01-01) [Artigo]
The electromechanical impedance (EMI) technique is considered to be one of the most promising methods for developing structural health monitoring (SHM) systems. This technique is simple to implement and uses small and ...
Tool Condition Monitoring of Single-Point Dresser Using Acoustic Emission and Neural Networks Models
(IEEE Transactions on Instrumentation and Measurement, 2014-03-01) [Artigo]
Identification and online monitoring of the dresser wear are necessary to guarantee a desired wheel surface and improve the effectiveness of grinding process to a satisfactory level. However, tool wear is a complex phenomenon ...
Utilization of Minimum Quantity Lubrication (MQL) with Water in CBN Grinding of Steel
(Materials Research-ibero-american Journal of Materials, 2014-01-01) [Artigo]
The use of cutting fluids is fundamental to machining processes, mainly when it comes to high heat generation, which is the case of grinding. Thus, lubrication and cooling provided by cutting fluids improve the final quality ...
Predictor-Corrector Primal-Dual Interior Point Method for Solving Economic Dispatch Problems: A Postoptimization Analysis
(Mathematical Problems in Engineering, 2012-01-01) [Artigo]
This paper proposes a predictor-corrector primal-dual interior point method which introduces line search procedures (IPLS) in both the predictor and corrector steps. The Fibonacci search technique is used in the predictor ...
Evaluation of different methods of cooling-lubrication in cylindrical grinding of advanced ceramic dip
(Materials Research, 2014-10-01) [Artigo]
The current work presents a study of alternative methods of cooling-lubrication for the external plunge grinding of advanced ceramics using diamond wheels. These two alternative methods, which are intended to reduce cutting ...
