Study of the Effect of Sulfamic Acid on Formation Cu-Se Compounds by CV and EQCM

Authors:	Dang, Thi Bich Hop Pham, Hong Quang Do, Thi Kim Anh Do, Phuc Quan
Keywords:	Cyclic voltammetry;EQCM;Cu-Se compounds;electrodeposition;thin films
Issue Date:	2014
Publisher:	H. : ĐHQGHN
Series/Report no.:	Vol. 30;No. 2 (2014)
Abstract:	A combination of Cyclic Voltammetry (CV) and Electrochemical Quartz Crystal Microbalance (EQCM) has been used to study the effect of sulfamic acid as a complexing agent on the formation of Cu-Se compounds. It has been found that sulfamic acid does not affect the deposition of Cu in the absent of Se. However, when Cu and Se are simultaneously, sulfamic acid was found to affect strongly the formation of Cu-Se compounds, namely it causes and facilitates the reactions forming Cu-Se compounds. Furthermore, at high concentration, sulfamic acid causes a mass-loss process, leading to a change of composition and a poor surface morphology. A suitable concentration of sulfamic acid can be concerned from these studies.

Issue Date:	2014
Publisher:	H. : ĐHQGHN
Series/Report no.:	Vol. 30;No. 2 (2014)
Abstract:	In this paper, we study the systems of generalized quasiequilibrium problems which includes as special cases the generalized vector quasi-equilibrium problems, vector quasiequilibrium problems, and establish the existence results for its solutions by using fixed-point theorem. Moreover, we also discuss the closedness of the solution sets of systems of generalized quasiequilibrium problems. As special cases, we also derive the existence results for vector quasiequilibrium problems and vector quasivariational inequality problems. Our results are new and improve recent existing ones in the literature.

Control Engineering: An introduction with the use of Matlab

Authors:	Derek P., Atherton
Keywords:	Control engineering;Kĩ thuật điều khiển
Issue Date:	2013
Publisher:	bookboon.com
Abstract:	The book covers the basic aspects of linear single loop feedback control theory. Explanations of the mathematical concepts used in classical control such as root loci, frequency response and stability methods are explained by making use of MATLAB plots but omitting the detailed mathematics found in many textbooks. There is a chapter on PID control and two chapters provide brief coverage of state variable methods. The approach adopted allows more time to be devoted to controller design by different methods, to compare the results and also to examine the effects of plant parameter variations.

Electrical Power

Authors:	W. J. R. H. Pooler
Keywords:	Electrical power;Năng lượng điện
Issue Date:	2013
Publisher:	bookboon.com
Abstract:	The book defines the units of electrical quantities from first principles. Methods are demonstrated for calculating voltage, current, power, impedances and magnetic forces in dc and ac circuits and in machines and other electrical plant. The vector representation of ac quantities is explained. Typical arrangements of electrical power networks are described. Methods for calculating fault currents and for the automatic isolation of faulty equipment are described.

Corporate Valuation and Takeover

Authors:	Robert Alan, Hill
Keywords:	Corporate valuation;Định giá doanh nghiệp
Issue Date:	2011
Publisher:	bookboon.com
Abstract:	This free book critically evaluates corporate equity valuation in today’s volatile markets using asset values, earnings, dividend policy, cash flow analysis and behavioural theory. The case for efficient markets and performance measures (based on yields and P/E ratios) published by stock exchanges worldwide to provide market participants with a framework for investment analysis is assessed. Finally, the two most important strategic decisions corporate management and investors will ever encounter are analysed; an unlisted company seeking a stock exchange quotation and a listed company preparing a takeover bid.
