Background: Bridge deck inspection is essential task to monitor the health of the bridges. Condition monitoring and timely implementation of maintenance and rehabilitation procedures are needed to reduce future costs associated with bridge management. A number of Nondestructive Evaluation (NDE) technologies are currently used in bridge deck inspection and evaluation, including impact-echo (IE),...

The maintenance and management of bridge is crucial to their normal operation. application big data technology makes the processing massive in process more timely accurate. In order evaluate status suspension operation period accurately timely, on basis summarizing sources bridge, wavelet separation method used separate waveform displacement at support bridge. Considering influence temperature ...

Due to the dwindling maintenance budget and lack of qualified bridge inspectors, bridge-management agencies in Taiwan need develop cost-effective inspection strategies preserve safety functionality their aging, natural disaster-prone bridges. To inform development such a strategy, this study examined big data stored Bridge Management System (TBMS) using knowledge discovery databases (KDD) proce...

Oscillators are kernel components of electrical and electronic circuits. Discussion of history, mechanisms and design based on Barkhausens observation. Discussion of a Wien Bridge oscillator based on the question: Why does this circuit oscillate ?

The use of implantable ventricular assist devices for the treatment of advanced, decompensated heart failure as a bridge to heart transplantation has experienced considerable evolution over the past decade. Improvements in the management and prevention of serious adverse events, and introduction of new continuous-flow rotary pumps that are smaller, more durable, and associated with fewer seriou...
