New Releases by Yoshio Hayashi

This colorfully illustrated multicultural children's book presents Japanese fairy tales and other folk stories—providing insight into a rich literary culture. Playful goblins with long noses, magic tea kettles and a delightfully brave hero who just happens to be one inch tall-these are some of the wonderful characters you'll meet in this collection of the 20 best-loved Japanese children's stories. Drawn from folklore and passed down for generations, these classic tales speak of the virtues of hard work, humility, kindness and good humor — "Once upon a time …" has never sounded so inviting. Commemorating the 50th anniversary of one of our all-time best-selling titles. With a new foreword, each story has been lovingly revised and reset, and all the sparkling illustrations appear in color for the very first time. With so many enchanting stories to choose from, young readers will have a delightful time deciding which is their very favorite. The Children's Favorite Stories series was created to share the folktales and legends most beloved by children in the East with young readers of all backgrounds in the West. Other multicultural children's books in this series include: Asian Children's Favorite Stories, Indian Children's Favorite Stories, Indonesian Children's Favorite Stories, Japanese Children's Favorite Stories, Singapore Children's Favorite Stories, Filipino Favorite Children's Stories, Favorite Children's Stories from China & Tibet, Chinese Children's Favorite Stories, Korean Children's Favorite Stories, Balinese Children's Favorite Stories, and Vietnamese Children's Favorite Stories.

Abstract: "A timed process calculus TCCT is introduced, to model computing mechanisms which deal with complicated time critical situations, where various events occur and each event occurrence can be affected by when and what events occurred so far. We often encounter this kind of phenomena, for which it seems significant to introduce a formal computing model. Considering the nature of the model, it is crucial at which time points and with what time intervals event [sic] occur. In order to deal with such temporal information, it is necessary to nicely control multiple time constraints on a single process. Therefore we define the process calculus TCCT so that a multiple number of labelled timers can be assigned to a single process and separately release each timer by referring to its label. In most conventional process calculi, it is assumed that everything in question can be described as processes, no matter how large the system is. There the main purpose of discussion is usually to analyse the ways of communication between such processes. In the real world, timed systems are very large and complicated, and, so are the processes which model them. In this calculus, however, such systems are considered only as an event generator, which is useful to simplify the situation and in the result to get simpler processes. This perspective is also a contribution of the calculus. In addition, in this paper we show that the practical feasibility of the calculus by actually using TCCT to implement a certain recognising devices [sic], besides discussing the calculus merely as a formal computing model. Finally with regard to a mathematical property of the calculus, it is demonstrated that an equality based on the conventional bisimulation is preserved by all contexts for a reasonable class of processes."

Electromagnetic fields are investigated in an inhomogeneous anisotropic media, or ''generalized Tellegen's'' media. To begin with some lemmas and theorems are given. Using these results, general representations of the fields and integral equations for the fields are derived for three cases of two media problems. The results are shown to be true for general many media problems. It is also shown that the solutions of the integral equations are equivalent to the fields in general media. These integral equations are three dimensional singular equations of Cauchy type kernel for which it is still an open question how to solve them rigorously and generally. Kernels of these integral equations are found to have tight connections with the tensor Green function which was introduced by Levine and Schwinger. The abstract operator method of Marcuvitz is studied in connection with these integral equations. (Author).
