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...

Detecting evolutionary community structure in dynamic weighted networks is important for understanding the structure and functions of networks. In this paper, an algorithm which considers the historic community structure of networks is developed to detect evolutionary community structure in...

In the present work, three fatty acid eutectics of capric acid (CA)–lauric acid (LA), capric acid–palmitic acid (PA), and capric acid–stearic acid (SA) were prepared through melt-blending followed by ultrasonication and were investigated as model phase change materials (PCMs); for...
