作者： j.fukuda Faculty of Engineering Kyushu Kyoritsu UniversityKitakyushu 807-8585Japan

＜正＞ A mesh generating system has been developed in order to prepare large amounts of input data which are needed for easy implementation of a finite element analysis. This system consists of a Pre-Mesh Generator, an Automatic Mesh Generator and a Mesh Modifier. Pre-Mesh Generator produces the shape and sub-block information as input data of Automatic Mesh Generator by carrying out various image processing with respect to the image information of the drawing input using scanner. Automatic Mesh Generator generates mesh of triangular elements in the arbitrarily shaped and multiple connected planar domain by using minimum necessary information. This generator has 3 methods of mesh generation for each sub-block, A) Regular Mesh Generation, B) Semi-Regular Mesh Generation and C) Irregular Mesh Generation. Any of them can be selected automatically according to the external form of sub-block or the state of domain. Mesh Modifier projects and modifies the pattern of generated mesh by Automatic Mesh Generator as required. This system simplifies the user’s task while saving manpower in carrying out the finite element analysis.

This review,which was adapted from a Tenth International Workshop on Tropical Cyclones(IWTC-10)report,discusses research findings and operational practices relevant to cyclone types and phase transitions(extratropical,subtropical,and tropical).The cyclone phase space(CPS)method is widely used in both historical investigations and real-time evaluation of cyclone type and transition;however,CPS parameter values depend on input data resolution,and universal thresholds do not currently exist to delineate when a cyclone transitions from one type to *** of phase transitions in a changing climate highlight potential latitude shifts in extratropical transition and increased potential for tropical transition,but realistic projections of future trends likely require high-resolution simulations that can capture the cyclone warm *** meteorological centers apply varied approaches to cyclone classification via CPS parameters and other criteria,some of which depend on the tropical basin,yet these approaches cannot fully address challenges in operational classification and subsequently in communicating risks associated with these phase *** recommend a multivariate historical assessment of tropical and subtropical cyclones across all basins in which they occur,including the South Atlantic Ocean and the Mediterranean Sea,to identify the potential for a more universal cyclone classification approach that meets operational needs.

The emergence of the tracheophyte-based vascular system of land plants had major impacts on the evolution of terrestrial biology, in general, through its role in facilitating the development of plants with increased stature, photosynthetic output, and ability to colonize a greatly expanded range of environmental habitats. Recently, considerable progress has been made in terms of our understanding of the developmental and physiological programs involved in the formation and function of the plant vascular system. In this review, we first examine the evolutionary events that gave rise to the tracheophytes, followed by analysis of the genetic and hormonal networks that cooperate to orchestrate vascular development in the gymnosperms and angiosperms. The two essentialfunctions performed by the vascular system, namely the delivery of resources （water, essential mineral nutrients, sugars and amino acids） to the various plant organs and provision of mechanical support are next discussed. Here, we focus on critical questions relating to structural and physiological properties controlling the delivery of material through the xylem and phloem. Recent discoveries into the role of the vascular system as an effective long-distance communication system are next assessed in terms of the coordination of developmental, physiological and defense-related processes, at the whole-plant level. A concerted effort has been made to integrate all these new findings into a comprehensive picture of the state-of-the-art in the area of plant vascular biology. Finally, areas important for future research are highlighted in terms of their likely contribution both to basic knowledge and applications to primary industry.
