A smart grid is a modernized power grid. Many novel technologies have been used to smart grids. One of the technologies is the wireless sensor network. In this study, a novel backbone communication network is proposed, which combines two different wireless technologies (the ZigBee and Wi-Fi protocol), to form a communication network between the transmission(More)
In this paper, we propose a novel wavelength demultiplexer based on metal-insulator-metal plasmonic waveguides with a nanoscale ring resonator. Its transmission characteristics are numerically studied using finite element method (FEM) simulations, and the eigenwavelengths of the ring resonator are theoretically calculated. For the proposed structure, we(More)
Internet of Things (IoT) has become a popular issue in academic research. The technology of Wireless Sensing Network can fully implement the concept of IoT. A WSN uses less expensive sensors to automatically monitor environmental factors and to transmit sensing data. Therefore, the cost of manually collecting sensing data can be largely reduced. WSNs are(More)
Calorimetric biochemical measurements offer various advantages such as low waste, low cost, low sample consumption, short operating time, and labor-savings. Multichannel calorimeters can enhance the possibility of performing higher-throughput biochemical measurements. An enthalpy sensor (ES) array is a key device in multichannel calorimeters. Most ES arrays(More)
Currently, Internet of Things (IoT) has become a hot issue. For agriculture, IoT techniques bring many advantages, such as lowering the time consumed and the manpower required by real time data collection. Taiwan is one of the main orchid exporters in the world, and orchid export accounts for over 70% of the total floral export in Taiwan, and the species of(More)
