To study the behaviour of a haemocyte when crossing a stenotic capillary, the immersed boundary-lattice Boltzmann method was used to establish a quantitative analysis model. The haemocyte was assumed to be spherical and to have an elastic cell membrane, which can be driven by blood flow to adopt a highly deformable character. In the stenotic capillary, the(More)
The ultra-wideband (UWB) communication system provides high accurate localization due to the high multi-path resolution capacity. This paper applies an improved TDOA method to achieve UWB localization in the mobile environment. The ETDGE algorithm for ranging and the Fang & iterative algorithm for locating the moving node are approached by an optimum(More)
In many bearing fault anomaly detection application, only positive (normal) samples are available for training purposes, other abnormal samples are difficult to be available. In order to solve these practical application problems, a novel model of one-class bearing fault detection based on SVDD and genetic algorithm is presented in this paper. The time(More)
EMG prosthetic hands are being extensively studied to meet with the need of the millions of physical disabilities who have lost a hand or both hands. But for most of existing multi-degree of freedom EMG prosthetic hands, shortcomings such as low intensity, high price, et al., have blocked them from practical realization. Low-degree freedom EMG prosthetic(More)
There are millions of people who have lost a hand or both hands due to acquired amputation or congenital limb deficiencies. In order to improve their quality of life, electromyogram (EMG) prosthetic hands have been developed to compensate for some daily activities which a cosmetic glove cannot do. However, most EMG prosthetic hands pursue the ability of(More)
A wireless ECG monitoring system suitable for the usage of athlete training and evaluation is proposed, which contains multiple client-side wireless ECG acquisition sub-systems based on MSP430, a central monitoring sub-system based on ARM and ECG analysis software on PC. The whole monitoring system constitutes a wireless sensor network with nRF905 wireless(More)
This paper presents a stability analysis method for piecewise linear delta operator systems. Based on a piecewise Lyapunov function, the stability of the piecewise delta linear systems can be established if a piecewise Lyapunov function can be constructed. Moreover, the Lyapunov function can be obtained by solving a set of linear matrix inequalities (LMI).
Continuous monitoring and analysis of vital parameters like SO2, heart frequency, breathing frequency is important for the prevention and management of cardiac heart failure. The cardiac sentinel allows continuous monitoring and recording of these parameters and automatic transmission of the collected data to the clinical server via an inbuilt GSM modem.
