A symmetric two-species competition system under the action of multiplicative noise, additive noise and periodic signal has been analytically studied by using two-state theory. The results indicate that signal-to-noise ratio of the system state variables exhibits a peak with multiplicative and additive noise intensities, i.e., a stochastic resonance phenomenon. © 2013 Indian Association for the Cultivation of Science.

Cloud computing is high scalability, high reliability, high resource utilization Characteristics. In this paper, according to the characteristics of the logistics information, combined with cloud computing technology to build the model of logistics information sharing platform based on cloud computing. On cloud computing technology application of key technologies in the logistics information sharing platform is analyzed. Finally, this paper has carried on the design of logistics information sharing platform based on cloud technology. With the use of logistics information sharing platform, the logistics information development play a powerful role in promoting. © (2013) Trans Tech Publications, Switzerland.

In statistical inference methods, Bayesian method is a method of great influence. This paper introduces the basic idea of the Bayesian method. However, the widespread popularity of MCMC samplers is largely due to their impact on solving statistical computation problems related to Bayesian inference. Markov chain Monte Carlo method is essentially a Monte Carlo synthesis procedure. The random sample of it is related to a Markov chain. It is a widely used stochastic simulation method. This paper mainly introduces Gibbs sampling, and its application in Bayesian statistics. We use a simple example to illustrate how to tackle a typical Bayesian problem via the MCMC method. © Owned by the authors, published by EDP Sciences, 2016.

In this study, α,ω-bis(3-(1-methoxy-2-hydroxypropoxy)propyl) polydimethylsiloxane and α-N,N-dihydroxyethylaminopropyl-ω- butylpolydimethylsiloxane were used to prepare block and graft waterborne polyureathane-polysiloxane copolymer dispersions. α,ω-bis(3-(1- methoxy-2-hydroxypropoxy)propyl)polydimethylsiloxane was synthesized by hydrosilylation, methoxylation and equilibrium reactions; α-N,N- dihydroxyethylaminopropyl-ω-butylpolydimethylsiloxane was synthesized via hydroxyl protection, alkylation, anionic ring-opening polymerization, hydrosilylation, and deprotection. Block and graft waterborne polyurethane-polysiloxane copolymer dispersions were prepared by the reaction of poly(propylene glycol) (PPG), toluene diisocyanate (TDI), 2,2-dimethylol propionic acid (DMPA), 1,4-butanediol (BDO), α,ω-bis(3-(1-methoxy-2- hydroxypropoxy)propyl)polydimethylsiloxane, and α-N,N-dihydroxy- ethylaminopropyl-ω-butylpolydimethylsiloxane. The water absorption of block and graft waterborne polyurethane-polysiloxane copolymer films decreased from 163.9 to 40.2% and 17.3%, respectively, when percent of polysiloxane (w/w) increased from 0 to 5%, and the tensile strength of the block waterborne polyurethane-polysiloxane copolymer films decreased while the tensile strength of graft waterborne polyurethane-polysiloxane copolymer films increased with increase of percent of polysiloxane. For graft waterborne polyurethane- polysiloxane films, the tensile strength would decrease when percent of polysiloxane was more than 3%. © 2013 Society of Plastics Engineers.

A information fusion diagnosis system was built to reflect the real condition of the mine hoist, to achieve automatical identification and accurate diagnosis of the mine hoist. There are so many limitations in the traditional combination rules of D - S evidence theory. So a new evidence synthesis formula is put forward. It is proved by example analysis that the diagnosis result based on the improved algorithm is more accurate, effective and feasible. © 2015 Technical Committee on Control Theory, Chinese Association of Automation.
