This paper proposes a practical unit commitment method, which is able to evaluate transmission network operation in terms of an economic perspective. We wish to consider the unit commitment problems: a power generation cost minimization problem, a profit maximization problem for a power producer, and a social cost minimization problem. The power producer's profits are equal to income by produced power minus production cost. The social costs are equal to production cost plus payment by customers. The power transaction prices in the power system are decided by short-run marginal cost theory. Also, this theory is able to transform the reliability of the network into economic value.

In mobile communications and wireless LAN, many signals are assumed to be incident on the base station and the access point. Analyzing multipath propagation structures is important to develop anti-fading techniques for high-speed digital radio systems. This paper presents a simulataneous estimation method of delay times, arrival angles and power levels of multipath waves. We obtained frequency-do-main data using an array antenna. We estimate the propagation parameters by means of a genetic algorithm. Simulation results show that the proposed method can estimate the propagation parameters properly.

This paper presents the optimal trajectory planning for a single-link flexible manipulator to suppress residual vibration. The Lagrangian approach in conjunction with the assumed modes method is applied to derive the equation of motion of the manipulator. Parameters of the equation are obtained from an identification experiment by using a genetic algorithm. In the trajectory planning, we express the joint angle by cubic spline function, and then use a tabu search method to find the optimal trajectory. The optimal trajectory thus obtained has the minimum vibration requirement. The effectiveness of the proposed method is verified by comparing simulation results with experimental ones.

We made experimental equipment for Induction Heating (IH). Recently Induction Heating is used as the method for heating in a rice cooker and a cooking heater. This IH equipment was made for electric power generated by small wind power generation or hydroelectric power under 100V. We used a parallel resonance circuit of inductance and capacitance. This equipment heated a steel wheel to 50℃ from 22℃ for 20 minutes with a power supply voltage of 38V. This electric circuit worked correctly. We'll find examples of utilizing this IH equipment after this.

The binding property of thirteen 12-diazacrown-4 derivatives for alkali metal ions was examined, and from these results we selected the heptyl group as the most suitable substituent for the monomer. Then the radical polymerization of Nacryloyl-N'-heptyl-12-diazacrown-4 and the subsequent reduction of the produced polymer by diborane-THF were carried out. The reduced polymer retained the high binding ability for the lithium ion, but the selectivity was unexpectedly low.

The Immanuel migration group settled in1891 to Imakane and aimed to establish a Christian village. It is very characteristic that this settlement was done in partnership with two different Christian denominations, namely Anglican and Presbyterian. A leader of the Presbyterian group was Tsunesaburo Amanuma. His descendants, the Amanuma family own some basic documents which were written by him. In these documents the details of the Anglicangroup's migration are described. The existing studies on this group ignored these documents and depended exclusively on indirect historical materials and hearsay. This paper aimed to correct the existing view of the previous studies by the decipherment of these basic documents to reconstruct the historical facts.

Bowling lessons are one of the choices given to the fifth grade students at Asahikawa National College of Technology. The aim of this essay is to make clear objectively that the bowling is suitable for us to do as a lifelong sport as well as appropriate material for physical education. We measured heart rates at Asahikawa Sky Lane on 31^<rd> May, 2004. The following results were obtained: (1) The characteristics of the fluctuation of heart rates during the bowling class: Heart rates average ranged from 80 to 125 per minute during the basic exercises, and during games and free exercises it was between 90 and 135 per minute. The range between them was 45 per minute. And the heart rate average of the three students was 108.2 per minute. As a result, we found that bowling is not only an excellent sport for safe and pleasant aerobics but also a suitable lifelong sport. (2) What should be done for improving the lessons: It is said that the proper heart rate level found by the warming-up is between 120 and 130 per minute. It is obvious that we should spare about five minutes to achieve a moderate heart rate during the basic exercise lessons. There is room for improvement in warming-up at the beginning of the class.

Automatically Guided Vehicles (AGVs) play an important role in realizing an autonomous decentralized production system. Up to day, most of the research on AGVs focuses on how they can acquire proper behaviors from a viewpoint of a multi-agent system. Recently, we proposed a new formula for the multi-agent system, in which an environment is adaptable to the agents as well as agents which are adaptable to the environment. In this paper, we proposed a new evaluation method for the AGVs environment, namely the AGVs path, by use of small world theory. Two characteristics, an averaged longest path and a clustering coefficient, in the small world are introduced to evaluate the AGV's path. Numerical calculation proves the proposed evaluation method gives us fruitful results to design the AGV's path.

The contents studied in Applied Mathematics are Vector Analysis, Complex Function, Laplace Transformation, Fourier Series and Fourier Transformation. These fields began or developed in the 19^<th> century. It is known that science developed in the 19^<th> century, and mathematics developed similarly. 19^<th> century mathematics was not handled in the lecture of History of Mathematics, so the author discusses 19^<th> century mathematics in concern with physics in this article. In the 4^<th> chapter, a detailed chronology was made by the author. The author expects that this article will become a reference for teachers who teach Applied Mathematics.
