似顔絵においては個人の顔特徴が端的に表現されると同時に、感性情報を付加することによって、より豊かな個人表現を行うことが可能である。本論文では、異なる表情を持つ二つの顔画像(学習サンプル)の組について、表情の特徴だけを表す表情ベクトルをFisherの線形判別法で決定する。さらに、主成分分析により顔特徴を表す成分と表情の特徴を表す成分とが混合した主成分に対応する固有空間(「特徴固有空間」と呼ぶ)を求める。次に、表情ベクトルと特徴固有空間からGram-Schmidtの直交化法により、顔部品の形状や配置の特徴を表す成分と表情の特徴を表す成分を分離した正規直交基底(「表情独立固有空間」と呼ぶ)を構築する。この表情独立固有空間を用いて、入力顔画像に異なる表情を付与する。合成した表情顔形状が本人の実写表情写真とどの位近いかを確かめるために主観評価実験を行い、表情独立固有空間を用いた表情合成方法の有効性を明らかにした。

Field surveys of the distribution of domiciliary cockroaches were conducted in Tokyo and Kawasaki during the period between 1972 to 1974. In Tokyo, dead cockroaches collected from various types of buildings following insecticide treatment by pest control operators were brought to the laboratory and identified. Among a total of 286 buildings surveyed, 172 (60.1%) were restaurants and snacks, 25 (8.7%) offices, 14 (5.0%) food factories, 12 (4.2%) residences and 12 (4.2%) supermarkets. A total of 2,802 cockroaches was collected including Blattella germanica (93.7%), Periplaneta fuliginosa (4.8%), P. japonica (0.5%), P. americana (0.8%) and P. australasiae (0.2%). However, the findings cannot be taken to represent the general tendency of cockroach infestation in Tokyo since a disproportionately high number of restaurants and offices, which are the principal clients of pest control services, were surveyed. A correlation between the type of structural property and established cockroach species was examined and a dominance of B. germanica was shown in all cases. This was especially striking in the case of structures constructed within the past 5 years. In Kawasaki, a total of 145 cockroach adhesive traps were set in offices, restaurants, stores, apartments, residences and farm houses on two occasions in both summer and winter. Species compositon of trapped 1,755 individuals was B. germanica (78.6%), P. fuliginosa (20.7%) and P. japonica (0.7%). B. germanica was dominant over P. fuliginosa in offices, apartments, restaurants and stores, while the opposite was true for residences. In farm houses, P. fuliginosa was most abundant followed by P. japonica. A distinct tendency for the abundance of B. germanica in urban buildings, P. fuliginosa in residences and P. japonica in farm houses was observed. Furthemore, P. japonica has never been trapped during winter, suggesting that they had entered diapause.

A three-dimensional seismic survey was carried out at the western Nankai Trough accretionary wedge from June 18 to August 18, 1999. This experiment was Japan-U.S. collaborative investigation on seismogenic zones. The cruise imaged an 8 X 80 km area with 81, 80km-long, high quality, seismic reflection lines, all of which have nearly continuous coverage.<BR>The main objective of our experiment was to image the plate boundary fault at which major earthquakes and tsunamis are generated. Our primary goal is to image the thrust and identify the boundary between aseismic and seismic zones for a large inter-plate earthquake.<BR>On-board two-dimensional data processing has been carried out. This gives us a significantly clear image of the inner structure of the accretionary wedge at our survey area. One impressive image of the profile shows the large thrust slice zone that is classified by our interpretation. A number of out-of-sequence thrusts have developed and are concentrated in the area where the water depth is approximately 4, 000 to 3, 000m. A decollement plane touches the oceanic plate (layer II) down at there in first. We identified that the boundary between the stable sliding zone (ocean-ward) and the unstable stick slip zone (landward) is located there. We propose that the boundary is the up-dip limit of the seismogenic zone. Further data processing is ongoing. A true three-dimensional structure will reveal much more details and a clear image of seismogenic zone at the Nankai subduction margin.

The protective device that was made with the elastic resin is excellent in restoration. Therefore, when the collision ship is removed even if the ship collides with it the form almost returns to an original form. Recently, we are doing the research that checks the characteristic of the protective device by the model experiment and numerical value analysis and use the urethane foam as a model. In the previous paper, we discussed the characteristic of the time that the ship penetrated into it statically. The bow model that we used is 1 kind and entrance angle is 35 degrees. In the present paper, we report about the research result in the time that changed the measure of the bow. The following results are obtained. (1) When the entrance angle of the bow becomes big, the slope of a reaction force-bow penetration curve becomes steep. At this time, the change rate of the slope becomes steep with the increase of the entrance angle. (2) When the curvature radius of the top becomes big, the slope of the reaction force-bow penetration curve becomes steep a little. The influence of radius curvature decreases when the entrance angle becomes big. (3) These results almost agree with the numerical value analysis and model experiment.
