Abstract

In this paper, the simulation model of the transaction plan that meets the energy-saving power generation dispatching is established by using the time series simulation method, and the factors such as the output characteristics, load characteristics and peak shaving characteristics of various energy sources are considered. The model can be solved by Cplex simulator. The simulation results can show the output mode of various power type units, and the daily output plan of each unit can be obtained.

Abstract

Fermented foods were likely to have been the first among all types of processed foods consumed by human beings. The role that fermented food plays is not only related to the development of civilizations and cultural relationships between countries but also related to the nutritional importance of its population. Of course, the early manufacturers of fermented foods didn't take into account the advantages of modern sciences, because enzymes and microorganisms were discovered just 150-200 years ago. For that reason, we can conclude why the ancient fermentation techniques were known to philosophers and alchemists, but not to biologists. It demonstrated that the fermentation mechanisms involved many secrets still undiscovered. Recently, applications of molecular techniques for analyzing and study the fermented foods have been explored. In this review, we provide answers with a critical vision to many questions for understanding the role of molecular techniques to discover the secrets of fermented foods such as how to evaluate the traditional fermented foods? Why using molecular techniques to study the fermented foods not else? Is the future will carry to us a boom in molecular technologies contribute to the detection of more secrets of the fermented food? [ABSTRACT FROM AUTHOR]

Abstract

A global frame of secure instant messaging system based on Microsoft MSN is proposed to solve the security problems that exist in instant messaging. A secure add-in is designed and integrated seamlessly into the MSN client utilizing interfaces of the MSN client. The identity based cryptography is introduced into the secure instant messaging field and thus a secure instant messaging key management module based on IBC is designed and implemented. At last, the results of the performance test of the add-in and key management module show that, in the precondition of being compatible to MSN, the system could solve the secure problems between instant messaging users such as key management, identity authentication, message encryption and authentication etc.

Abstract

When steady supersonic flow hits a slim wedge, there may appear an oblique transonic shock attached to the vertex of the wedge, if the downstream pressure is rather large. This paper studies stability in certain weighted partial Hölder spaces of the oblique transonic shock attached to the vertex of a wedge, which is against steady supersonic flows, under perturbations of the upstream flow and the profile of the wedge. We show that under reasonable conditions on the upcoming supersonic flow and the slope of the wedge, such transonic shocks are structural stable. Mathematically, we solve an elliptic-hyperbolic mixed type in an unbounded domain, and the flow field is proved to be C1. Copyright © 2015 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]
