We analyze the relations between the stock market and a stock bulletin board system (BBS) in Japan. Previous studies in the USA found that the characteristics of messages posted on stock BBSs can predict market volatility and trading volume. We develop hypotheses based on the results of those analyses and apply statistical analysis to the data about(More)
Here we present a new resist design concept. By adding dilute cross-linkers to a chemically amplified molecular resist, we synergize entropic and enthalpic contributions to dissolution by harnessing both changes to molecular weight and changes in intermolecular bonding to create a system that outperforms resists that emphasize one contribution over the(More)
Signature verification is one of the most popular subjects in pattern recognition. Many kinds of verification methods for online handwritten signatures have basically used the individual features of signatures. However, how to reflect inter-stroke information extracted from handwritten multi-stroke signatures in the verification has not been well(More)
Various verification methods for on-line handwritten signatures have been proposed; however, reflecting inter-stroke information in the verification has not been considered. Hence, this paper suggests a verification method that uses Shape Context. In this paper, the verification method is divided into two methods. One is the basic method and the other is(More)
