The problem of modeling based on Lie group is studied for space manipulator system with characteristics of nonlinear and strong coupling. By introducing the corresponding relation between rigid body motion and SE(3) and the exponential product method, a recursive model and its matrix representation based on Lie group is obtained through forward and backward recursive process, which has advantages...
Apurinic/apyrimidinic endonuclease 1 (APE-1), a kind of multifunctional protein widely-distributed in the body, plays an essential role in the DNA base excision repair and serves as multiple possible roles in the response of human cancer to radiotherapy and chemotherapy. In this work, an ultrasensitive solid-state electrochemiluminescence (ECL) immunosensor is designed to determine APE-1 based on...
Customer education refers to the extent to which company provides the instructional activity about product knowledge and skills. The research method adopted by prior literature is mostly theoretical or conceptual, relevant empirical research is scare, hampering the development of theory and practical application. Taking fund product as an example, and based on the perspective of customer readiness,...
This paper studied mathematical model of doubly-fed induction generator (DFIG) based wind turbine generation system under unbalanced voltage. A dual-PI current control strategy was proposed to improve the performance of DFIG's rotor side convert (RSC) under asymmetrical voltage condition. The symmetrical component theory is employed to decompose asymmetrical three-phase variable such as voltage and...
The dynamic routing algorithms are the most important in the routing model of traffic engineering. In this paper some dynamic routing algorithms of traffic engineering are discussed. In this case, a dynamic routing algorithm based on bandwidth and delay is proposed. It is effective and convenient for the algorithm by a practical simulation.
