Rationality in mathematics is discussed by analyzing historical facts concerning infinitesimality. Several views containing Platonism, formalism and falsificationism are suggested to analyze rationality.

This paper presents a study performed to investigate the steady-state operational strategies of UPFCs in the Jeollanam-Do system in Korea. The objective of the study was to determine the UPFC operating points under normal and contingency conditions. The study consists of developing load flow models to simulate different load levels with and without UPFCs in the system, assessing the effectiveness of UPFCs by contingency analysis, and introducing optimal corrective actions for removing voltage problems caused by contingencies. The paper describes analytical tools, models and approach. It also includes analysis and discussion of the study results. The paper contributes to the area of transmission operational studies with FACTS applications.

China has witnessed tremendous changes especially in the field of packaging industry after the reform and opening policy commencing in early 1979. Thanks to the reform and opening policy by Deng Xiaoping, a former leader of China, packaging industry has been selected as one of the specialized industries, and this policy has made great achievements in the field of packaging. The total volume of packaging industry now ranks the first in the overall industry in China and this indicates that this industry is taking a great role to bust up economic growth of China. In this paper, The facts and forecasts of packaging industry and education in China are introduced.

In this paper the performance of meta-heuristics algorithms such as GA (Genetic Algorithm), DE (Differential Evolution), PSO (Particle Swarm Optimization) and SA (Simulated Annealing) for the problem of TTC enhancement using FACTS devices are compared. In addition to that in the assessment procedure of TTC two novel techniques are proposed. First the optimization algorithm which is used for TTC enhancement is simultaneously used for assessment of TTC. Second the power flow is done using Broyden - Shamanski method with Sherman - Morrison formula (BSS). The proposed approach is tested on WSCC 9 bus, IEEE 118 bus test systems and the results are compared with the conventional Repeated Power Flow (RPF) using Newton Raphson (NR) method which indicates that the proposed method provides better TTC enhancement and computational efficacy than the conventional procedure.
