This paper presents a computational method for a confidence region of identified parameters which are affected by measurement noise and error contained in prescribed parameters. The method is based on sensitivities of the identified parameters with respect to model parameter error and measurement noise along with the law of error propagation. By conducting numerical experiments on simple models, it is confirmed that the confidence region coincides well with the results of numerical experiments. Furthermore, the optimum arrangement of sensor locations is evaluated when uncertainty exists in prescribed parameters, based on the concept that square sum of coefficients of variations of identified results attains minimum. Good agreement of the theoretical results with those of numerical simulation confirmed validity of the theory.

Ten male skillful heavy gymnastic players who have been excercising over 6 years including participants in the All Japan Student Championship of Heavy Gymnastics and 6 unskilled players who have been practicing for less than one year are subjected for this study on the measurment of the body structure. In general, the maximum girth of both righ and left brachiums and antebrachiums was found significantly to grow in the skilled group when the results were compared with the unskilled group. The difference was appearently expressed by the fact having muscular excercises with chinning, supporting and standing still. It could therefore be considered that the muscular strengthen of the brachiums and the antebrachiums is the most importantly necessary for the training program in the future. In the lower extremity, no significant difference was found in the skilled group vs the unskilled group, and the development of the lower extremity in the heavy gemnastic players is generally found to be relatively lower. Upon the above results, the development of the upper extremity, in particular musculi biceps brachii, musculi triceps brachii and musculi brachioradialis is remarkable, while the lower extremity was not significant in the skilled group. It would therefore be required to set a plan for the training with the balanced development of the upper and lower extremities. It would also be considered to be necessity for the training of the upper extremity in the unskilled group.

Recently, with the increase in the number of colorectal cancer patients, the computer-aided diagnosis (CAD) systems which support a doctor"s diagnosis are essential for early stage treatment. In this paper, we introduce a SVM hardware architecture for CAD system for colorectal endoscopic images with NBI magnification findings. Additionally, we also propose a pyramid style structure with multi-SVMs for effective diagnosis image segmentation.
Maintenance Modelling for a System on Navy Ship

Systems equipped in ships are limited in maintenance activities when the ship engages in mission, or voyage, because navy ships do not have enough capacity to load enough spare items. Some failures can be repaired even during mission, but other failures cannot be repaired; these failures are repaired after the mission and the ship is in harbor. We assume that the former failure occurs with probability p and repaired instantly and minimally, and the latter failure occurs with probability 1-p and repaired minimally after the mission. The probability depends on the amount of shipboard spare items and many navies in the world manage it by making a list called COSAL (Consolidated Shipboard Allowance List). We formulate the cost rate and the mean availability of the system as functions of the number of missions.
