A pillow type computer input device is proposed. The interface is designed to move computer cursor as the user expect by using his or her head movement. A supporting and care devices around the bed often becomes barriers for the care and assist task for the patient. The proposed pillow type interface is designed not to disturb the care and assist tasks. The head movement of the user is estimated by the four pressure sensors under the pillow. In order to improve the user-friendliness of the interface, the pillow is mounted on the sliding mechanism. Due to these pressure sensors, rotating head movement around the neck and nodding movement of the head can be measured quantitatively. Considering the head movement, the computer cursor is moved by using the original algorithm.

ALS is a degenerative disease which affects the patients muscular activity in feet and hands, leading to a bed ridden status. The loss of independency affects their will to live, for this reason an environmental control system to handle the home appliances and make telephone calls is proposed. The system uses a tablet as a visual human interface so that the patient can select the desired appliance by selecting the corresponding item on the tablet screen. Based on the remaining patient’s abilities an input device that detects slight finger movement is proposed. In this paper three types of input devices are considered and their performance is evaluated by four ALS patients. Their comments about the usage of the devices are discussed in this work. Finally the environmental control was implemented on an ALS patient home and their impressions were satisfactory for the patients, relatives and care-givers.

开河寺石窟现存三个北朝洞窟和一尊隋初的摩崖大佛。三个洞窟最早的铭文为东魏武定五年(547),摩崖大佛铭文为隋开皇元年(581),大佛旁台座铭文为北魏永平三年(510)。这表明从北魏到隋朝,当地佛教徒持续在此造营供奉。笔者考察了造像及铭... 详细信息

开河寺石窟现存三个北朝洞窟和一尊隋初的摩崖大佛。三个洞窟最早的铭文为东魏武定五年(547),摩崖大佛铭文为隋开皇元年(581),大佛旁台座铭文为北魏永平三年(510)。这表明从北魏到隋朝,当地佛教徒持续在此造营供奉。笔者考察了造像及铭文,发现了另一尊摩崖大佛的痕迹,认为铭文中的“镇国王”是指隋文帝,“双丈八”最初应是双像弥勒佛,敬奉“二圣”隋文帝和独孤皇后。此外,据豆卢通及其子僧奴有关资料,“镇国王像双丈八”铭文极有可能是在隋开皇八年(588)之后题刻的。

The interaction of the shock reflected at a secondary diaphragm with the primary contact in six cases, i.e. the strengths and shapes of the contact surface are different, were explored by numerical study. The influences of the strength and shape of the contact on the developing wave pattern and the quality of the test gas are illustrated by many kinds of figures (e.g. the time-distance diagrams of the acoustic impedance contours on the axis, the acoustic impedance contours, and the time histories of pilot and static pressures).

The details of the shock propagated through the right angled multiple elbows (mainly double elbow and fourfold elbow) are investigated by the numerical study. Computations were carried out by solving the two-dimensional compressible Navier-Stokes equations by using the total variation diminishing (TVD) scheme. Computations were performed for six types of elbow (two types of double elbow and four types of fourfold elbow) and two incident shock Mach numbers (Ms=1.5, 2.3). The effects of the direction and number of the bends in the stabilizing, merging and attenuating processes of the shock are numerically explored by various diagrams such as pressure contours, pressure distributions on the walls and time histories of the pressure contours, and the strength of the shock front at the location of about 20 times the length for each type of elbows was displayed.

在象征北魏平城时代的云冈石窟中,有七座高13-17米的大佛。这些大佛以北魏皇帝为原型雕凿,是体现北魏佛教特性的重要作品。作者认为,在初期昙曜五窟四座如来像中,第20、19、18窟大佛为"鲜卑皇帝大佛",第16窟大佛则为"中国皇帝大佛"。三座"鲜卑皇帝大佛",以《魏书》所载初代道武帝的奇特容貌为基础,用魁梧的身躯、巨大的耳朵和眼睛强调了鲜卑王的彪悍。"中国皇帝大佛"则身着汉式衣装,表情睿智,俨然是知书达礼的中国皇帝。从"鲜卑皇帝大佛"到"中国皇帝大佛",反映了北魏英雄形象的转变。对于第13窟并排站立的七身中国式如来像,作者认为与天子七庙制有关,很可能是"七帝七佛造像"。
