This study investigates the determinants of initial public offering (IPO) underpricing by focusing on variables relating to information asymmetry, investor sentiment, and corporate governance and examines whether the determinants of IPO underpricing in high-technology and non-high-technology...

A mathematical model of a free piston linear engine is established. The motion characteristics as well as the natural frequency map of the free piston are established. Then, its motion characteristics are successfully explained from the oscillation point. The full simulation model is built up in...

A diesel engine is modified for homogeneous charge compression ignition (HCCI) combustion with dimethyl ether. With and without knock, in-cylinder pressure is acquired, and in-cylinder temperature, rate of heat release (ROHR), pressure rise rate and pressure rise acceleration obtained. Wavelet...
