This work demonstrates a real-time bridge structure health monitoring device (HMD) with using three 1-axis accelerometers, Gateway, and analog to digital converter (ADC). The proposed HMD achieves the features of low cost and data synchronization of three 1-axis accelerometers. Furthermore, we develop a packet acquisition program to receive the data from(More)
The speech modification is a mechanism of changing speech characteristics and prosody for some specific applications. It is used in voice conversion, pronunciation correction, tone perception, and language learning. The most important part is the change of pitch in an utterance. Pitch extraction is an essential process for speech modification. This paper(More)
This paper proposes a structure health monitoring device (HMD) with using three 1-axis accelerometers, microprocessor, analog to digital converter (ADC), and data logger for long span bridge. The proposed monitoring system achieves the features of low cost and data synchronization of three 1-axis accelerometers. Furthermore, we develop a packet acquisition(More)
Bridges are the important pivots of traffic, the damage of bridges can cause the severe cost of human life and property. In Taiwan, many bridges have exceeded their 50-year life span. The strength of these old bridges is no longer affordable to the severe nature disasters. In other words, the bridges in Taiwan are likely to suffer from the damage. Since(More)
Carbon monoxide (CO) poisoning from natural gas water heaters is a common household accident in Taiwan. We propose a wireless and batteryless intelligent CO sensor for improving the safety of operating natural gas water heaters. A micro-hydropower generator supplies power to a CO sensor without battery (COSWOB) (2.5 W at a flow rate of 4.2 L/min), and the(More)
Directed cell migration requires dynamical control of the protein complex within focal adhesions (FAs) and this control is regulated by signaling events involving tyrosine phosphorylation. We screened the SH2 domains present in tyrosine-specific kinases and phosphatases found within FAs, including SRC, SHP1 and SHP2, and examined whether these enzymes(More)
Our proposed scour monitoring system utilized low-cost commercial sensors, hall-effect sensors (unit price <; $1) that is capable of real-time measuring bridge pier scour with resolution of ca. 2.5 cm, and overall cost for single sensor node of our work is at least 40% less expensive than existing work. The hall-effect sensor is evaluated under(More)
