This study investigates whether there was a housing price bubble in Beijing and Shanghai in 2003. The existence of a bubble can be interpreted from (abnormal) interactions between housing prices and market fundamentals. This paper introduces an enhanced framework, with the combination of...

Artificially strengthened filter bed is an innovative wastewater treatment technology based on the coupling of eco-contact oxidation filters and artificial wetlands purification mechanism. By small scale laboratory equipment, the effects of cascade aeration, filter type, filter clogging and...

This paper develops a two stage game model with two competing firms in a mixed oligopolistic market, a public firm and a private firm, and only the public firm giving its manager an incentive contract. The paper presents three types of public firm owner¡¯s objective function and each objective...

We consider a particular four state spin system composed of two Ising spins (sx, σx) with independent hopping parameters κ1 κ2, coupled by a bilinear Yukawa term, ysxσx. The Yukawa term is solely responsible for breaking the global Z2 × Z2 symmetry down to Z2. This model is intended as an...

Construction time performance (CTP) and flexibility in approaches to project time planning have been shown to be significantly associated. This raises interesting questions about how effective planning and control to facilitate flexibility in overcoming unexpected problems may be achieved. Case...

The optimal layout problem of circle group in a circular container with performance constraints of equilibrium belongs to a class of NP-hard problem. The key obstacle of solving this problem is the lack of an effective global optimization method. We convert the circular packing problem with...
