A Study on the effect of C3H8O3 and C8O7 electrolytes for electro chemical machine performance of titanium alloys [PDF]

open access: yesE3S Web of Conferences
Electrochemical Machining is a non-traditional machining process that uses electro- chemical reactions to remove materials from the workpiece. In this work , micro hole are produced on the titanium alloys with combination of C3H8O3 and C8O7 electrolytes ...

Interrelated Main-Sequence Mass-Luminosity, Mass-Radius and Mass-Effective Temperature Relations

open access: yes, 2018
Absolute parameters of 509 main-sequence stars selected from the components of detached-eclipsing spectroscopic binaries in the Solar neighbourhood are used to study mass-luminosity, mass-radius and mass-effective temperature relations (MLR, MRR and MTR).

Dynamic MRR Function Optimization Using Calculus of Variations [PDF]

open access: yesMathematical Problems in Engineering, 2010
A dynamic machining model to optimize the control of material removal rate (MRR) for a cutting tool undergoing the considerations of fixed tool life and maximum machining rate is established in this paper. This study not only applies material removal rate mathematically into the objective function, but also implements Calculus of Variations to ...

Optimal Strategies for Sinusoidal Signal Detection [PDF]

open access: yes, 2002
We derive and study optimal and nearly-optimal strategies for the detection of sinusoidal signals hidden in additive (Gaussian and non-Gaussian) noise. Such strategies are an essential part of algorithms for the detection of the gravitational Continuous ...
