Summary: Daily continuous spirometry is expected to detect lung disease initial symptoms that occur in daily contexts. Current medical spirometers are insufficient for such usage because they force uncomfortable conditions for users, such as pinching their noses with a clip and holding a mouthpiece in their mouths. To solve this issue, we propose an e-textile-based wearable spirometer called SpiroVest that estimates lung behavior from torso-girth movements. It does not require any uncomfortable conditions that interfere with daily activity. In addition, our wearable spirometer is able to estimate accurate respiratory volume against variety of postures by a simple and posture-independent error reduction mechanism.

Summary: This paper proposes a novel e-textile-based pressure sensor. Textile is a common material in our life, used in such items as sheets, seats, and clothing. If these items are equipped with sensor functions, they can invisibly assist humans without significant lifestyle changes. Our sensor is suitable for mass production and durable in daily hard use cases. The sensor is woven with common weaving machines with a special manner and its material is a common low-cost conductive fiber that does not use special and costly materials, such as optical fiber. The sensor mechanism is supported by the textile structure; thus our sensor has durability for frictional force and scratch occurring sometime in daily context. In this paper, we also introduce two example usages of our textile sensor: a bed-size body pressure sensor for anti-pressure-ulcer treatment and a wearable foot-pressure sensor for walk and skill analyses.

[3] Unit selection using k-nearest neighbor search for concatenative speech synthesis Poster session / Mizuno, Hideyuki / Takahashi, Satoshi Proceedings of the 3rd International Universal Communication Symposium 2009-12-03 p.379-382

Summary: We propose a new approach to rapidly identifying adequate synthesis units in extremely large speech corpora. Our aim is to develop a concatenative speech synthesis system with high performance (both speech quality and throughput) for various practical applications. Utilizing very large speech corpora allows more natural sounding synthesized speech to be created; the downside is an increase in the time taken to locate the synthesis units needed. The key to overcoming this problem is introducing state-of-the art database retrieval technologies. The first selection step, based on simple hash search, tabulates all synthesis unit candidates. The second step selects N best candidates using nearest neighbor search, a typical database retrieval technique. Finally, the best sequence of synthesis units is determined by Viterbi search. A runtime measurement test and subjective experiment are carried out. Their results confirm that the proposed approach reduces the runtime by about 40% compared to using only hash search with no degradation in the quality of synthesized speech for a 15 hour corpus.

[6] Two Learning Schemes in Information Retrieval Quantitative Models (1) / Yu, Clement T. / Mizuno, Hirotaka Proceedings of the Eleventh Annual International ACM SIGIR Conference on Research and Development in Information Retrieval 1988-06-13 p.201-218

Summary: Two methods are given to improve weighting schemes by using relevance information of a set of queries. The first method is to estimate parameter values of two independence models in information retrieval -- the binary independence model and the non-binary independence model. The parameters estimated here are used to calculate optimal weights for terms in a different set of queries. Performance of this estimation is compared to the inverse document frequency method, the cosine measure, and the statistical similarity measure. The second method is to learn optimal weights of the non-binary independence model adaptively by a learning formula. Experiments are performed on three different document collections CISI, MEDLARS, and CRN4NUL for both methods, and results are reported. Both methods show improvements compared to the existing weighting schemes. Experimental results show that the second method gives slightly better performance than the first one, and has simpler implementation.
