The NCKU Smart Campus Project: An Experiment Towards Smart Cities
Tay-Sheng Jeng

“Smart city” has become the new trend of the world’s city development in the 21st century. The traditional cities are composed of concrete, steels, bricks, and glass. Unlike traditional cities, a smart city develops its nervous system through the Internet, supporting the daily life of billions of people. The city's nervous system manages the operation of space and infrastructure, and then with …

Thermoelectric phenomena on thermoelectric generator surface under temperature oscillation.
Wei-Hsin Chen

Thermoelectric generators (TEGs) are a device to convert heat into power. Because low-temperature waste heat can be harvested and turned into electricity by TEGs, they are a promising facility in the green energy development. However, the efficiency of TEGs is low. How to improve the efficiency of TEGs via materials, system design or operation has become an important task for TEG development. …

Spectrum Analysis of Cry Sounds in Preterm and Full-Term Infants
Li-mei Chen

Previous studies indicated that crying behavior of full-term and preterm infants show significant different patterns due to immature neurological development of preterm infants. Long-time average spectrum (LTAS) was used to analyze the cry phonation of 26 infants under four months old. Sixteen of them are full-term and the other 10 infants are preterm. The results of first spectral peak (FSP), …

Design of gate-all-around silicon MOSFETs for 6-T SRAM area efficiency and yield
Meng-Hsueh Chiang

Advanced transistor structures such as the 3-D tri-gate MOSFET have been adopted at the 22-nm CMOS technology node because they can better suppress short channel effects than the conventional planar bulk MOSFET structure. Gate-all-around MOSFETs relevant for the 11.9 nm CMOS technology node are optimized with device dimensions following the scale length rule. Variability in transistor performance …

Autophagy-preferential degradation of MIR224 participates in hepatocellular carcinoma tumorigenesis
Hsiao-Sheng Liu

Autophagy and microRNA (miRNA) are important regulators during cancer cell tumorigenesis. Impaired autophagy and high expression of the oncogenic microRNA MIR224 are prevalent in hepatocellular carcinoma (HCC); however, the relationship between the 2 phenomena remains elusive. In this study, we are the first to reveal that autophagy selectively regulates MIR224 expression through an …

Revolutionary Views on Periodic Bands in Polymer Spherulites
Eamor M. Woo

Historically, in the past 60 years, continuous spiral twisting of polymer lamellae caused by chain folding induced unbalance surface stresses had been believed as a plausible mechanism for common optical ring-banding behavior in polymer spherulites. With progress of powerful advanced instrumentation and newer discoveries of diversified patterns (e.g., birefringent vs. non-birefringent …
