Transition and Parsing State and Incrementality in Dynamic Syntax
( Masahiro Kobayashi ),( Kei Yoshimoto ) 한국언어정보학회 2007 학술대회 논문집 Vol.2007 No.-
This paper presents an implementation of a gramar of Dynamic Syntax for Japanese. Dynamic Syntax is a grammar formalism which enables a parser to process a sentence in an incremental fashion, establishing the semantic representation. Currently the application of lexical rules and transition rules in Dynamic Syntax is carried out arbitrarily and this leads to inefficient parsing. This paper provides an algorithm of rule application and partitioned parsing state for efficient parsing with special reference to processing Japanese, which is one of head-final languages. At the present stage the parser is still small but can parse scrambled sentences, relative clause constructions, and embedded clauses. The parser is written in Prolog and this paper shows that the parser can process null arguments in a complex sentence in Japanese.

<P>Tall birch trees allocate extra resource due to aboveground temperature elevation to bud and male flower production rather than to plant growth. Saplings increased only plant growth under warming. Size-dependent response should be considered. We experimentally heated canopy organs of tall birch trees (Betula ermanii Cham.; 18-20 m high) growing at a high latitude to determine how leaf phenology, plant growth, and bud and male flower production might shift in response to increases in aboveground temperature during global climate change. We warmed the canopies with infrared heat lamps fixed to steel pipe scaffolds built around the trees. The temperature of the warmed canopies increased by approximately 1 A degrees C. Warming extended the length of the growing season of canopy leaves (by accelerating leaf flush and delaying leaf fall), and significantly increased the numbers of buds and male flowers per shoot. Bud production and shoot length were positively correlated in both warmed and control branches. However, warming did not increase canopy shoot lengths. The intercept value of the positive regression slope between bud production and shoot length for warmed branches was higher than that for control branches. Thus, canopy warming had a direct positive effect on the bud production but had no indirect effect via increases in shoot length. Our experiment showed that tall birch trees allocated extra resources made available by increased aboveground temperature to bud and male flower production rather than to plant growth.</P>
HUMAN INTERFACE TO MULTIMEDIA DATABASE SYSTEMS
( Kazuhide Higuchi ),( Masahiro Tada ),( Akihiro Ogino ),( Ayumi Sato ),( Emi Yano ),( Hayato Kobayashi ),( Toshikazu Kato ) 한국감성과학회 2002 춘계학술대회 Vol.2002 No.-
To transmit users`` intentions that vary with each person, intuitive and bi-directional interactions between users and a computer are necessary. We considered these interactions by dividing them into two spaces, physical space and informational space. Informational space supports human thinking process by arranging and visualizing much information. Physical space reproduces the real world where various restrictions exist to virtual space. From the viewpoint of three aspects - contents model, kansei model and context model - we defmed the style of the interaction between user and multimedia database. In this paper, for the purpose of examining the way to realize the interaction based on these models, we developed interior design coordination support system and garden coordination system, and then evaluated them.
Surface durability of powder-forged roller treated by shot peening

To investigate the influence of shot peening on the surface durability of powder-forged rollers, the case-hardened powder-forged rollers with a forging density of 7.5 g/cm3 treated by the single shot peening and the double shot peening were fatigue-tested under a slidingrolling contact condition. The surface roughness, the surface hardness and the surface compressive residual stress of the rollers were increased by the shot peening. In addition, the pores near the roller surface were deformed by the shot peening. The failure mode of all the test rollers was spalling due to subsurface cracking. The fatigue lives of all the test rollers were improved by the shot peening, and that of the test roller S08, which was shot-peened with the hardest steel shots in this experimental range, was especially improved. The surface durability of the test roller S08 was also most improved by the shot peening. Cracks became difficult to occur and propagate under the roller surface since the pores near the roller surface were deformed by the stronger shot peening. In this study, double shot peening,which generally restrains the increase in surface roughness, was not particularly effective for the improvement in the surface durability of the powder-forged rollers, because the influence of tangential force on fatigue was not always great in a case of subsurface cracking.
