In a society whose issues related to sustainability have become increasingly important, the IT area has been responsible for some of the environmental problems that society faces. In this context, Green IT appears as a way of combining available resources to sustainable and economic policies in organizations, generating benefits for the environment and business. The adoption of Green IT practic...

The effect of the thickness of ceramic membrane on the productivity of microbial fuel cells (MFCs) was investigated with respect to the electricity generation and domestic wastewater treatment efficiencies. The thickest ceramic membrane (9 mm) gained the highest coulombic efficiency (27.58±4.2 %), voltage (681.15±33.1 mV), and current and power densities (447.11±21.37 mA/m2, 63.82±10.42 mW/m2) ...

In order to solve the problem of highway standardization management ability description, evaluation and improvement, in this paper, a highway standardization management maturity evaluation model has firstly been put forward. Moreover, the influence highway qualitative factors of implementing the standardized management have analyzed and its evaluation index system has constructed. Furthermore, ...

We study the behavior of the critical price of an American put option near maturity in the jump diffusion model when the underlying stock pays dividends at a continuous rate and the limit of the critical price is smaller than the stock price. In particular, we prove that, unlike the case where the limit is equal to the strike price, jumps can influence the convergence rate.

An alternative technique for the geometric test of machining centres was developed, to congregate metrological reliability with operational and economical advantages, when comparing to methods classically used for such task. A touch probe is used on a 3-axis vertical machine center to check against artifacts calibrated on a coordinate measuring machine (CMM). By comparing the results obtained f...
