Recently, there are many information security and privacy issues related to the Radio Frequency Identification (RFID) system, hence further pervasive application is seriously restricted. Recently two RFID authentication protocols named ESAP and WISP for RFID security authentication are designed based on the monotonically increasing time-stamp. Message exchange becomes much more dynamical and anonymous...
A PID control is developed for robust control of EGR (Exhaust Gas Recirculation) system in a gasoline engine. First a GT-power model of the gasoline engine with EGR system was built and verified. Then a PID controller was built using Simulink/Matlab and coupled with the GT-power engine model. A suitable tuning strategy for the PID controllers is also developed. Its response characteristics and performance...
To support the various services provision in a single network bearer with any device, anywhere, and anytime, it is necessary to build triple converged networks from network, service and application three convergence levels. The paper depicts them from three sides, i.e. the core carrier networks (optical Internet), telecom and broadcast networks convergence requirements.
How to shrink the gap between the service provision capacity and the QoS requirements of user applications is one of key issues of the naive OBS in multi-service carry environment. This paper extended the concept of optical burst, and proposed a novel OBS architecture (i.e., G-OBS). Besides, this paper also discuss some enhancements of G-OBS from node functional models, hierarchy optical burst framing,...
In order to get a robust control for a gasoline engine EGR (exhaust gas recirculation) system, a fuzzy PID controller is developed and its performance is studied by comparing to the normal PID controller. First a GT-power model for the gasoline engine (with EGR) is constructed and verified. Based on this model, a PID control system and a fuzzy PID control system are developed. Then the step signal,...
A genetic algorithm with a penalty function is used to optimize the intake and exhaust system of gasoline engine, whose middle range torque was deceased a lot due to the adding of a catalyst. First two GT-power models are built based on experimental results of the gasoline engine with/without catalyst. Then the intake pipe length and diameter and exhaust pipe length and diameter are chosen as the...
The engine performance and pollutant emissions of a commercial SI engine using butanol-gasoline blended fuel are investigated in details. First dyno-experiment tests are carried out. By comparing with the pure gasoline fuel, it is found that the influence of butanol-gasoline blend on engine performance is small for low engine speed. There is a torque drop at high load but it can be recovered easily...
Integration of episomal human papillomavirus (HPV) DNA in infected cervical lesions during malignant progression is frequently observed, but the importance of integration is poorly understood. We have studied immortalization by HPV-18 of human cervical cells as an in vitro model system. Here, the status and expression of HPV-18 DNA in precrisis ectocervical keratinocytes was compared with that in...
