The Creation

Grid Onput is a set of novel two-dimensional codes comprising extremely small dots. The present authors recently developed software to overlap the dot codes on the user's designed sheet, to create a content to replay audios, to create a standalone application to replay multimedia, and to create an application to replay multimedia on iPad. Simply touching the dot codes with a speaking-pen and/or a dot-code reader enables users to directly access the corresponding digital information; a maximum of four mediums can be easily linked to each dot code icon. In collaboration with schoolteachers all over the world, one of the authors, Shigeru Ikuta, has been creating a variety of original self-made content and conducting various activities at both general and special needs schools. This chapter outlines the recent development of the state-of-the-art Grid Onput dot code technology and presents basic information regarding the creation of original teaching materials using newly developed software and the use at both general and special needs schools.

This is a paper that summarizes the state of the practice and state of the art in the prediction of seismic behavior of cylindrical liquid storage tanks. It can be divided into five parts. In the first part the seismic performance of these types of tanks during recent   earthquakes is brielfly reviewed. From this review it becomes evident that a large percentage of these tanks have failed or suffered severe damages. The different types of failure are classified into several categories. The second part of the paper discusses the desing of some of the thank that suffered damages andthe state of the practice is summarized by reviewing present seismic code desing provisions. Thirdly, the soundness of these code provisions is analyzed in view of the state of thank.  Results obtained in recent theoretical and experimental investigations of such behavior are summarized and implications regarding needed improvement in seismic desing are assessed. Results from analyses of an existing  thank using different methods are presented and compared. An improved procedure for the practical seismic resistant desing of these thanks is outlined in the fourth part of the paper. A series of practical desing rules which provide extra margins of safety are offered and the extra cost required is discussed. Finally, recommendations for future research to improve the desing and construction of this type of liquid storage thanks are formuated.

Key Issues

Cultural diversity—the degree to which there are differences within and between individuals based on both subjective and objective components of culture—can affect individual and group processes. However, much is still unclear about the effects of cultural diversity. We review the literature on cultural diversity to assess the state of the art and to identify key issues for future research. This review emphasizes the importance of understanding different types of cultural diversity and their independent and combined effect on team performance. We identify key contributions to the study of cultural diversity and discuss frontiers for future research.

The discovery of high temperature superconductivity has motivated a vigorous study of the physics of Hubbard systems. Here, the properties of the spin aspects of the Hubbard system in two-dimension, in the strong coupling limit, are briefly reviewed, with the basic ideas, some of the fundamental questions and the state of the art introduced.

Plasma Techniques

Abstract LASER techniques are widely used for pre-opening in combination with a final manual or automated wet chemistry decapsulation. Even if most of the ICs may be opened today, and if opening the recently introduced Ag wires packages have been solved with novel chemical recipes, the need for a greener and safer solution is still there. Plasma techniques combined with LASER can be a promising solution to these challenges. In this paper, after a presentation of the state of the art of the different techniques available in laboratories nowadays, the latest solution combining LASER and acid or plasma etching is presented. The paper compares the results obtained with these solutions on Cu an Ag wires devices with pros and cons for each solution. The results presented show the benefits, the constraints and the limitations of each technique regarding the different types of wires used in industry.
