PURPOSE To evaluate the daytime fluctuation of intraocular pressure (IOP) in patients with primary angle-closure glaucoma (PACG) after trabeculectomy. PARTICIPANTS AND METHODS A total of 176 patients with PACG participated in a clinical trial of trabeculectomy with or without releasable sutures. Applanation IOP was measured at 5, 7, and 10 AM, and 2, 6,(More)
In Mobile Wireless Sensor Networks (MWSNs), location information of nodes is the basis of many applications. Compared with that in a static network, the localization issue in a mobile network is more difficult due to uncertainty of node positions, thus much more challenges are brought to MWSNs. In this paper, we propose three localization models to evaluate(More)
In order to improve the present conditions that water sources require manual on-site control, decentralized management and Network interruption, this paper presents a LabVIEW-based network complementary monitoring system design. System achieves field device communication through the RS485 bus, using the Modbus protocol, then, realizes the communication(More)
Under the background of the Age of Big Ocean, much emphasis have been paid on the marine development and utilization of the ocean. So the Underwater Wireless Networks (UWSNs) have been attracted much attention in the industrial community and the academic community. In this paper, we compare the performance of three localization algorithms: the DV-Hop, the(More)
This paper studies force couple leveling system of heavy hydraulic press. A multi-input and multi-output nonlinear model is established on the basis of analyzing hydraulic structure and block kinematics. A cascade control structure is designed for the leveling system. In the outer loop, each corner follows the average displacement other two corners adjacent(More)
