Ordering Strategy for Fresh Agricultural Products in External Financing Condition

This paper firstly introduced the two stage supply chain consisting of single agricultural product producer and fund restraint retailer.Then,it analyzed the influence of bank interest rate on order quantity,wholesale price and expected profit of retailer and producer on the condition of retailer taking external loan strategy.Studies have shown that when the bank interest rate is in(0,0.9),the order quantity of agricultural products is a decreasing function of bank interest rate; when the bank interest rate is in(0,1),wholesale price of agricultural products decreases with increase in the bank interest rate; when the bank interest rate is in(0,0.6),the expected profit of retailer is a decreasing function of bank interest rate; when the bank interest rate is in(0,1),the expected profit of producer decreases with increase in the bank interest rate.Finally,through simulation calculation examples,it verified suitability of the conclusion,in the hope of providing reference and application value for management of supply chain.

Strategies for Improving Tourism English Teaching

Tourism is an emerging industry in China, known as the "sunrise industry" and "invisible trade". Though started late, with the rapid development of the national economy, it has been developing at an amazing speed. According to statistics, by the end of 2011, there were 23,690 travel agencies; the number of domestic and foreign tourists has grown exponentially every year. Particularly, inbound and outbound tourism market is booming. Europe, the United States and other English-speaking countries have become major tourist source markets of China; a large number of high-quality foreign tourism practitioners are urgently needed. Thus, tourism English teaching has played a very important role in the training of practitioners who are proficient in English, but also have high level tourism skills. Although at present, the education has accumulated a wealth of experience, has made significant progress, in the actual teaching, there are many problems existing. This article puts forward some constructive suggestions for improvement, combining with the local tourism resources.

Study of the Option Ordering Policy concerning Perishable Farm Produce Based on Revenue Sharing Contract

This paper considers the two-echelon supply chain system which consists of single agricultural producers and retailers,and analyzes the impact of sharing ratio on the option ordering quantity,and retailers and producers' expected profits.Studies have shown that in the case of decentralization,when the revenue sharing ratio is between 0 and 0.3,the option ordering quantity of farm produce is a decreasing function of the sharing ratio; when the revenue sharing ratio is between 0.3 and 1,the option ordering quantity of farm produce is an increasing function of sharing ratio; when the revenue sharing ratio is between 0.421 and 1,the agricultural producers and retailers' expected profits are an increasing function of sharing ratio.Finally,through the numerical calculation,the applicability of the conclusions is verified,to provide a reference for the supply chain management practices.

Application of Classical Garden Design in Landscaping of West Sichuan Plain

Taking"Lotus Garden Residential Area"in Dayi County,Chengdu City,on the west Sichuan Plain for example,the signifi cance of combining ecological technologies and landscape design was elaborated,and the means of controlling urban fl ood and waterlogging were explored from the perspective of the basic unit of urban construction,the residential area,so as to offer a new sustainable thought for the environment design of future residential areas.

Quantum Corrections on Tunneling Radiation by the Generalized Uncertainty Principle

Based on the generalized uncertainty principle (GUP), the researchers find that the quantum gravity affects the Klein-Gordon equation exactly. Hence, the Klein-Gordon equation which is corrected by GUP will be more suitable on the expression of the tunneling behavior. Then, the corrected Hawking temperature of the GHS black hole is obtained. After analyzing this result, we find out that the Hawking temperature is not only related to the mass of black hole, but also related to the mass and energy of outgoing fermions. Finally, we infer that the Hawking radiation will be stopped, and the remnants of black holes exist naturally.

Emotion of Physiological Signals Classification Based on TS Feature Selection

This paper propose a method of TS-MLP about emotion recognition of physiological signal.It can recognize emotion successfully by Tabu search which selects features of emotion’s physiological signals and multilayer perceptron that is used to classify emotion.Simulation shows that it has achieved good emotion classification performance.

On the Existence for Some Special Primitive Elements in Finite Fields

Let F_q be a finite field of characteristic p. In this paper, by using the index sum method the authors obtain a sufficient condition for the existence of a primitive elementα∈ F_(q^n) such that α + α^(-1)is also primitive or α + α^(-1)is primitive and α is a normal element of F_(q^n) over F_q.

A-序列倒数和的一个注记(英文)

An infinite integer sequence {1≤a1<a2<…} is called A-sequence,if no ai is sum of distinct members of the sequence other than ai.We give an example for the A-sequence,and the reciprocal sum of elements is Σ1/ai>2.065436491,which improves slightly the related ai upper bounds for the reciprocal sums of sum-free sequences.
