An approach for energy of activation derived from the temperature dependence of life time
Author: Parakhar Singh
Abstract: The metallic element piston Al 11wt% Si alloys SC100, ACA8, A4032 were tested in conjunction with A2618-T6 regarding their mechanical properties and their thermal fatigue behavior. The alloy A2618 shows an improved elongation to failure and better yield stress compared to the opposite alloys by maintaining the low constant of thermal enlargement (CTE). Thermal fatigue experiments confirmed that the Coffin-Manson equation may be used for all times time rediction with the coefficients CP = zero.0385, KP = -0.377 comparable for A2618, whereas Kp =-0.45 for ACA8 and SC100 is obtained. The energy of activation derived from the temperature dependence of life time was calculable as letter of the alphabet = zero.5eV as typical for metallic element alloys.

Artificial work of that the theoretical half includes all necessary problems to formulate the total differential equations governing the overall motion of the whirligig beneath discretionary initial conditions
Author: Uttakarsh Agrawal
Abstract: This paper revisits the matter of a whirligig in a very uniform field once one purpose on the symmetry axis is fastened in area. it's AN instructive and artificial work of that the theoretical half includes all necessary problems to formulate the total differential equations governing the overall motion of the whirligig beneath discretionary initial conditions. Each mathematician and Lagrange formulations area unit mentioned. Moreover, closed type analytical solutions area unit derived for the regular precession and therefore the nod. The numerical integration of the equations was achieved victimization the quality Runge-Kutta theme ODE45 offered in MATLAB®, that was at the start applied to the totality of Euler’s equations and so to Lagrange’s equations. Also, in house RK2 and RK4 Runge-Kutta likewise as Crank-Nicolson schemes were applied in conjunction with the constraint for energy conservation. The standard of the numerical answer was evaluated by testing the conservation of total energy likewise as angular momenta within the variety of residuals within the corresponding Euler’s dynamic equations.

A security system for cut back the traffic accident rate, scale back the loss of products, and attain the automated analysis of safety performance
Author: Sachin Puri, Mayak Sharma
Abstract: This style is to ascertain a freight security system with time period communication and active safety observation. Its purpose is to cut back the traffic accident rate, scale back the loss of products, and attain the automated analysis of safety performance; these system is an online of vehicles system with security because the core that building by vehicle MHz, computer observation software system and communication system. It perceives vehicle safety standing, protects security, RMON and command by intelligent vehicle MHz and computer observation software system that freelance analysis and development. It creates the 4-layer communication protocol stack supported GPRS / surgical operation / TCP / scientific discipline and transport security knowledge. The look constructs an online of vehicles composed of freight vehicles, centre, specific phones that's ready to protocol conversion, wired / wireless network transmission for signal and full-duplex communication for instruction. The system is intended for dynamic security observation of trunk transport, is attain time period automatic security police work and remote time period / delay artificial security observation with early warning of non-normal driving, emergency rescue for traffic accidents, the good anti-theft for whole vehicle and regulation by two-way and multi-level operate, etc. The system provides intelligent and active answer for freight security. Enterprise additional refined and dynamic manages transport through this technique, is achieved to cut back traffic accidents, scale back losses and improve the management potency.
