In this paper a design and implementation method of smart energy hub is presented. This energy hub can incorporate diversified renewable energy, automated and intelligent management. The design of it deeply considered on the use of renewable energy and the reliability of power supply for critical load. It can be used as a basic unit of smart distribution grid, and it designs to operate in both grid...
This paper proposes statistic learning based Qlearning algorithm for Multi-Agent System, the agent can learn other agents' action policies through observing and counting the joint action, a concise but useful hypothesis is adopted to denote the optimal policies of other agents, the full joint probability of policies distribution guarantees the learning agent to choose optimal action. The algorithm...
It is very important to explore the combination of college English teaching and multimedia technology, because it is the unstoppable trend. The advantage and existing problem of multimedia in college English teaching is analyzed. The cooperative learning and the teaching evaluation mode with "the double connection" are integrated to play the role of multimedia technology in college English...
A fuzzy multiple-attribute group decision making method is proposed for the design schemes evaluation of the yarn tension detection and control schemes in rapier looms. Firstly, important degrees of every attributes from each expert are considered. The individual opinions of each expert are integrated with the similarity of the decision group. And the synthesized weights of each expert are calculated...
This essay takes 199 listed companies between October 23, 2009 and December 31, 2011 as samples to study the relationship among intrinsic value of the company, investor sentiment and the IPO under-pricing in the growth enterprise market. Results show that the intrinsic value of the company, investor sentiment and corporate governance is the main factor to affect GEM IPO under-pricing, while industry...
A new algorithm is suggested in this paper to solve discrete Lyapunov matrix equations. First, we design the algorithm to solve the matrix equations, of which coefficient matrices are of Frobenius form. Then, we extend this method successfully to general discrete Lyapunov matrix equations by similarity transforming their coefficient matrices. Finally, numerical results show that the new algorithm...
Petri Net (PN) has proven to be quite effective tool for graphical modeling, mathematical modeling, simulation, and real time control by the use of places and transitions. However, information imprecision and uncertainty exist in many real-world applications, and PNs found themselves inadequate to address the problems of imprecision and uncertainty in data. Therefore, the Fuzzy Petri Net (FPN) was...
Representing and identifying the topological relations between fuzzy spatiotemporal regions over time have an important significance in reasoning fuzzy spatiotemporal relations. The research issue of topological relations between fuzzy regions over time has attracted a lot of attention in the recent years. However, modeling topological relations needs to be further developed and it is still an open...
Neuro marketing is still less than a decade since it emerged. Although Magnetic Resonance Imaging (fMRI) has already applied to the practice by marketing practicers, it is controversial in the academic field. The authors reviewed neuromarketing academic papers so far from the aspect of product, service marketing, customer's buying decision, brand, price and perceived quality. The strength and shortage...
The purpose of the study was to investigate digital divide issue among urban and rural k-12 schools in Chinese economically developed regions. The researchers selected three representative primary schools (one from urban area, one from rural area and one is located in urban area but all of its students are from rural area) to explore the issue. The study is quantitative by nature and random sampling...
The study aims to exam if there were significant differences among urban and rural elementary schools in the implementation of ICT education. The study focused on information technology curriculum. A questionnaire according to three dimensions (learning, instruction, surroundings of learning) was the measurement tool for the study. The target population was all 5th grade schools students from three...
Angelica and Astragalus, Chinese herbal medicine, are used as immunostimulants for enriching the blood, anti-tumor and antioxidation effects. However, the synergistic mechanisms of antioxidant effect have long been the object of intensive study. We investigated the deferring senile effect of AAP on aging mice by determination of the contents of monoamine oxidase (MAO) in brain, hydroxyproline (Hyp)...
Studies on anti-oxidation effects of alcohol extract of Juglans Mandshurica leaves (AEJL) on mice with irradiation injury induced by X-ray was evaluated. The Multi-Dimentional Analysis (MDA) contents and the superoxide dismutase (SOD) activities in liver were measured in four groups including normal control group, irradiating control group, low dose of AEJL group and high dose of AEJL group. Compared...
Based on the view of cycle life in industrial cluster, this article elaborates the industrial cluster of Jinzhou County Textile in Hebei Province. This article confines four characteristics including scale, industrial net, industrial innovation, and industrial threshold to identify the industrial development by researching amount documents and some scholar's suggestion. Through analyzing the investigated...
It is of great importance to evaluate the practical listening and speaking competence of college students effectively. However, such competence is affected by many factors. Among these factors, many are comparatively very fuzzy, and influence each other. Comprehensive evaluation Indicator system based on fuzzy matter-element for listening and speaking competence of college students is constructed...
Dwellings are where the people live in. For a large number of existing traditional dwellings, people are more concerned about its habitability. Aimed at the current situation of residential streets in Quzhou, the article analyzes the influencing factors of the habitability based on the Reconstruction examples of current traditional examples, thinking of the measures that how to improve the living...
Based on the view of cycle life in industrial cluster, this article elaborates the industrial cluster of Jing County rubber tube in Hebei Province. This article confines four characteristics including scale, industrial net, industrial innovation, and industrial threshold to identify the industrial development by researching amount documents and some scholar's suggestion. Through analyzing the investigated...
This paper investigates the effect of institutional holding on idiosyncratic volatility and information flow. We document that firms with larger pretrade institutional ownership have more access to firm-specific information, which leads to larger idiosyncratic volatility. Institutional trading, with Fund as an exception, has no effect on idiosyncratic volatility and private information. Generally,...
Program Design is the first course to understand the kernel theory and the programming thought for the freshmen. If they can study well, they will have a good foundation to study later, keep interesting to the computer programming. Otherwise they will lose interest to study programming even be afraid of it. In order to improve teaching quality in the class and make students interest in learning, according...
This paper empirically studies the impacts of various corporate governance mechanisms on earnings management of listed Chinese firms from 2006 to 2008. We use eight variables to quantify various corporate governance mechanisms including ownership structure and executive compensation for 3468 listed firms sample. They include the concentration of shareholding among the ten largest shareholders, whether...
