by using the trigonometric uniform splines of order 3 with a real tension factor, a numericalmethod is developed for solving a linear second order boundary value problems (2vbp) withdirichlet, neumann and cauchy types boundary conditions. the moment at the knots isapproximated by central finite-difference method. the order of convergence of the methodand the theory is illustrated by solving tes...

Multi-criteria shortest path problems (MSPP) are called as NP-Hard. For MSPPs, a unique solution for optimizing all the criteria simultaneously will rarely exist in reality. Algorithmic and approximation schemes are available to solve these problems; however, the complexity of these approaches often prohibits their implementation on real-world applications. This paper describes the development ...

It is of great interest to understand the nanowelding metallic nanoparticles induced by laser illumination due its potential for offering convenient and controlled means shape-conversion fabrication nanodevices. However, real-time kinetics process were rarely investigated in literature. In this work, we applied fluorescence microscopy directly image silver (AgNPs) shined with continuous wave at...

Abstract Predictive maintenance has revealed as one of the paradigms Industry 4.0. This paper addresses a complete system for acquisition, computing, monitoring and communication ventilation equipment in underground tunnels based on TCP/IP protocol accessible via WEB services. Not only does proposed collect different sensor data (temperatures, vibrations, pressures, tilt angles or rotational sp...
