A DUPLICATED NETWORK STRUCTURE FOR AN LTE-BASED TRAIN CONTROL COMMUNICATION
The International Union of Railways has decided to migrate railway communication technology from being GSM-based to LTE-based or LTE-R. As a leading country in LTE space, South Korea will launch the train control system based on LTE by 2016. To ensure the most reliable train operation in this system, a fully duplicated network structure with overlaid radio cells is needed. Existing methods and res...... hiện toàn bộ

BASIC POWER ALLOCATION STRATEGIES FOR PLUG-IN HYBRID ELECTRIC VEHICLE CHARGING STATION
The high penetration of electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs) can cause serious impact to the entire grid: from power plants to local distribution systems. In particular, the demand charging of EVs may vary over stochastic with time. Uncoordinated EVs charging may increase the load with all the time, which increases the peaks, even can possible produce super-high pea...... hiện toàn bộ

MECHANISM OF TRIVALENT CHROMIUM ELECTRODEPOSITION USING Cr(III)-CONTAINING BATH WITH AND WITHOUT INORGANIC ADDITIES
Cathodic polarization technique was used for different Cr(III)-containing baths to explore the effect of inorganic additives on the mechanism of trivalent chromium electrodeposition. The presence of cations in the Cr(III)-containing bath can support a good condition for the diffusion of Cr3+ complexes from the bulk electrolyte to the cathode surface, thus improving the reduction of the Cr-complex....... hiện toàn bộ

APPLYING THE VIEWPOINT OF INTERACTIVE PEDAGOGY INTO TEACHING THE OCCUPATIONAL PSYCHOLOGY SUBJECT FOR STUDENTS AT HUNG YEN UNIVERSITY OF TECHNOLOGY AND EDUCATION
This paper describes the nature of “viewpoints of interactive pedagogy” and its implications for a teaching process. Simultaneously, the authors suggest solutions to realize the viewpoints on the basis of evaluating the shortcomings and limitations in the practice of teaching occupational psychology while teaching students at Hung Yen University of Technical Education. Therefore, these viewpoints ...... hiện toàn bộ

STUDY TO BUILD MEASURING SYSTEM OF FORCE ON THE CRANK PRESS MACHINE FOR UPSETTING PROCESS
Upsetting force is a very important factor. It determines quality, efficiency and avoids defects when stamping tubes. In this study, the design of measuring system of upsetting tube force on the crank stamping machine was investigated. A principle of force sensor was placed in the mold system on the crank stamping machine. The principle of force sensor was based on piezo electricity, the deformati...... hiện toàn bộ

Determination of structural and ground state properties of some materials using density functional theory
Structural optimization is potentially important to determine the chareristic of a new material, especially in nano-material science. Density functional theory, which have been applied extensively in recent years, emerges as an efficient method to study real materials applied in many desciplines of nano science and technology. In this report, we introduce biefly the theory and its application in t...... hiện toàn bộ
