The simplified equivalent by using the short circuit impedance has been used for analyzing the prospective transient recovery voltage of the large power system. But it sometimes generates untorelable error in the rate-of-rise of TRV when using the Thevenin equivalent source. This paper provides the new equivalent by using the multi-port theory. The application of the new method to the sample system gives satisfactory accuracy compared with the short-circuit equivalent.

Normality is one of the most common assumptions made in sampling and statistical inference procedures without suffering from lack of attention. Its results may lead to an invalid conclusion. We present several testing procedures that can be used to evaluate the effects of departure from normality using concrete examples by hand or with the aid of Minitab. The goal is to influence prospective teachers in order to learn statistical concepts and techniques for testing normality on the basis of the didactical theory.

This note examines a situation where a risk-neutral insurer and a risk-averse individual (prospective insured) negotiate to reach an arbitration point of the price of insurance over the terms of an insurance contract in order to maximize their respective self-interests. The situation is modeled as a Nash bargaining problem. We analyze the dependence of the price of insurance, which is determined by the Nash solution, on the parameters such as the size of insured loss, the probability of a loss, the degree of risk-aversion of the insured, and the riskiness of loss distribution.

This study firstly examined 18 prospective secondary mathematics teachers' understanding of the nature of definitions and the use of the dynamic geometry software Sketchpad to not only improve their understanding of definitions, but also their ability to define geometric concepts themselves. Results indicated that the evaluation of definitions by accurate construction and measurement enabled students to achieve a better understanding of necessary and sufficient conditions, as well as the ability to more readily find counter-examples, and to recognize uneconomical definitions, and improve them.

Social support is regarded as a complex construct which has long been suggested to have direct and buffering effects on patients' wellbeing and emotional adjustment to cancer. Cross-sectional and prospective studies show a positive association between perceived social support and psychological adjustment following cancer treatment. Research findings suggest that the evidence for the relationship between social support and cancer progression is sufficiently strong. This report points out the importance of social support in cancer and provides recommendations for health care professionals.

In this paper, two major theories of effective medium for composite materials are studied, which provide the average dynamic mechanical properties of particulate composites carrying elastic waves on the basis of the concept of self-consistent scattering of waves. These two theories are also compared in detail with each other to delineate the difference in the underlying ideas and their limitation of applicability. Furthermore, prospective directions for potential improvement of the theories are found. Numerical results for three particulate composites are given and discussed.

In tins paper, we outlines the pricing concept that developed over the years, and illustrates how these rules apply in practice using railway fare, price discrimination in railway travel. We review tile prospective solution of rail fare system reflecting the customer need on the decision making and consider fare design structure. Specifically, we focus on the price range using the PSM(price sensitivity measure). And set up the framework for fare structure design.

Objectives : This study is to report the effect of herbal medicine and acupuncture on a clinical pregnancy. Methods : From february 2014 to july 2014, a prospective analysis study was performed in 20 patients after taking her medicine and acupuncture treatment. Results : After treatment, two patients naturally became pregnance and one patient became pregnance after in vitro fertilization-embryo transfer (IVF-ET). Conclusions : This study suggests that herbal medicine and acupuncture treatment are useful and shows possibility to increasing pregnancy rates.
