The present work considers a T-shaped standing-wave thermoacoustic system with an electrical heater confined in the bottom stem and two temperature-controllable heaters (TCHs) enclosed in the bifurcating branches. With the heater placed at the bottom stem set to 1100K and TCHs be adiabatic,...

Illumination factors can affect growth of microalgae and HCO3− fixation. In order to optimize microalgae growth in culture system and HCO3− fixation from wastewater, the effects of light source, light interval on the growth of microalgae, Chlorella sp. and Scenedesmus obliquus sp., were...

Thermoacoustic instability occurs in many modern combustion systems. It most often arises due to the coupling between unsteady heat release and acoustic waves. Transient energy growth of acoustic disturbances could trigger thermoacoustic instability in a non-normal combustion system. In this...

The present work considers energy harvesting by implementing both thermo- and piezo-electric power generation modules on a bifurcating tube, which produces dual-temperature thermoacoustic oscillations. The present system distinguished from the conventional standing-wave one does not involve heat...

In this work, three different-diameter energy harvesters driven by turbulent air flow and rainwater are designed. Experiments are conducted first on the air-driven harvesters to gain insight on the energy conversion process. Unlike conventional blade-involved systems, the present setup involves...

We study the optimal technology licensing contracts with network effects and investigate the welfare implications when the product innovator is an insider that acts as a Stackelberg leader. We show that (i) the market is fully covered when relatively small network intensity matches quality...

We exploit parent- and subsidiary-level data for publicly listed firms in Thailand before, during, and after the 1997 Asian Financial Crisis to investigate the extent to which firms with different types of ownership restructure their business portfolios, in terms of divestitures and...

Infrastructure has played a major role in China's rapid development. Over the past decade the road network expanded by more than 40 percent, water production grew by more than 50 percent, and China has become the world's second largest energy producer. However, foreign direct investment in...
