Effects of the different ultrasonic powers on copper electrodeposition from non-cyanide alkaline baths by using pyrophosphate as complexing agent were investigated by different electrochemical methods. Cyclic voltammetry and current transient measurements were used to characterize the nucleation...

Effect of copper sulfate on CuZn alloys electroplating from non-cyanide baths are investigated by different electrochemical methods. Cyclic voltammetry and current transient measurements are used to characterize the CuZn alloys electroplating system in order to analyze the nucleation and growth...

In this paper, a new environmental-friendly electrolyte containing sulfuric acid and tartaric acid has been used as the substitute of chromic acid for anodization. The work discussed the influence of anodizing voltages on the fatigue life of anodized Al 2024-T3 by performing fatigue tests with...

An alkaline bath was developed for electroless deposition of Co–W–P thin films on a copper substrate. Effects of pH values, various concentrations of reducing agent, and different powers of ultrasonic on composition, microstructure, and magnetic properties of the films were investigated. It...

CoAg films were prepared by ionic liquid electrodeposition to replace conventional aqueous electrodeposition on a copper substrate. Effects of different EMIC concentrations on composition, microstructure and magnetic properties of CoAg films were investigated. With the increase of...

The quality and safety traceability system of agricultural products is an important measure to protect the quality and safety of agricultural products. Farmers and food enterprises are main operators of the traceability system. If they are effectively encouraged to practice traceability system,...

In China, the area of existing buildings in urban and rural has exceeded 43 billion m2 at present and more than 90% of them are high energy consumption buildings, which have poor thermal insulation performance, low energy efficiency technologies and equipments, and severe energy waste in HVAC...

This paper attempts to make use of a Copula-based GARCH (Generalized AutoRegressive Conditional Heteroskedasticity) Model to find out the relationships between the volatility of rubber futures returns in the Agricultural Futures Exchange of Thailand (AFET) and other four main markets, namely,...

As Chinese economy system has been depended more on the import of petroleum with the development of China, the change in the price of international oil have caused concern among economists and policy makers. This paper is to present a financial Computable General Equilibrium (CGE) model of the...

In this paper, we improve Lee–Seo’ bimodal image segmentation model using a regularization term. This regularization term will maintain the smoothness of the level set function and decrease the level set function’ oscillations around the desired steady state when the noise level is lager....
