STUDY AND SIMULINK OF CONTROL WIND ENERGY SYSTEM USING SRG GENERATOR
The paper simulinks wind system uses the Matlab/Simulink commutated generator. Evaluation of the output voltage quality stability of the control system of the wind power generation system using the SRG generator in the condition of wind speed change at no-load and load change when the wind speed remains the same. The results of simulation show that the stable output voltage value of has been ensur......

INTEGRATION PROCESS OF VIETNAM THROUGH PERIODS AND EMERGING ISSUES
Nowaday, open and integration is necessary demand of nations to exist and develop, depending on the different society - economy conditions, it has a different application. In Vietnam need integration has very early, but this term only was used in the documents of the eighth national party (1996), since the integration process of our country increasingly deepened and has achieved much success, but ......

HERMITE INTERPOLATION POLYNOMIALS IN COMPLEX DOMAIN
This paper establishes general Hermite interpolation polynomial in complex domain. At the same time, we evaluate the error of this interpolation polynomial based on complex integrals. Especialylly, when the multiple of the interpolation points is equal, we give Jacobi interpolation polynomial.

BUTT-JOINT BETWEEN SUS-304 STAINLESS STEEL AND SS400 STEEL BY GTAW PROCESS
In this research, the changes in the microstructures and mechanical properties in the welding zone and heat-affected zone (HAZ) of the welds between 304 stainless steel and SS400 carbon steel by Tungsten Inert Gas (TIG) with ER-309L welding rod were investigated. The formation of the micro-structure in areas, including the columnar-dendritic, was investigated by micro-cope equipment. The tensile s......

A STEADY-STATE POWER GENERATION METHOD AND STACKED LSTM IN EVENT DETECTION FOR HOUSEHOLD APPLIANCES
Non-Intrusive Load Monitoring (NILM) is an energy monitoring system that has gained popularities in recent years for improving energy saving. NILM for home electricity management provides useful information on home appliances, for example, estimating electricity consumption of individual appliances from electric power measurement and habits of consumers in using electricity. Moreover, this system ......

The Maize Production in Vietnam: Situation and Policy Implication
This study analyzed the trend in maize production in Vietnam and estimated a production model while determining factors affecting change in output. Response coefficients were estimated from time-series data in the period 1986 to 2011 using the double-logarithm model. Estimated parameters results in model indicated that the maize production also had positive response to the price of maize, the fert......
