The abuse of online-game bots has seriously hindered the development of online-game related business. However, in China there's no complete survey on game bots up to date yet. This paper we present an investigation of online game security issues, including bot behaviors and corresponding counter-measures. It shows that the increasing bots abusing damage the game business seriously and there are still...
During the first decade of this century, the online games are developed rapidly in China. But the virtual items transaction problems hinder the development of online games. Traditional trading models cannot meet the demand of both security and convenience at the same time. In order to improve the traditional transaction models, this paper presents a more secure transaction platform by embedding a...
A dual-buck full-bridge inverter (DBFBI) is proposed. The inverter solves the shoot-through problem of each bridge leg which exists in bridge-type inverter, so the dead time between the switches neednpsilat be set, and thus waveform quality of the output voltage and reliability of the inverter can be improved. The DBFBI also increases the input-voltage utilization rate and reduces the voltage stresses...
This paper proposes a push-pull forward three-level converter (PPF TL converter) for high-voltage fuel cell applications. It integrates the advantages of the TL converter and the PPF converter. It can operate at both three-level (3L) mode and two-level (2L) mode, so it is suitable for wide input voltage application, such as fuel cell power system. Half of the switches sustain half of the input voltage...
