The experiment proves that the method is useful and effective. Its identification rate is up to 90%, which is 20%-30% higher than that of using hand geometry or palm prints singly,thus it can be widely used in highly demanded security field, such as finance, entrance guard, etc.展开更多

The emergence of the university academies is the inevitable result of the contemporary university education seeking its own development. Starting from the connotation, background and logic of existence of the modem university academies, the author of this paper carries out researches on university academies, which is of certain reference values and promotion to the popularization and development of the university academies in the contemporary era.展开更多

In the introduction, l will propose an historical reconstruction of the debate, and focus in particular on Russell and Kripke＇s treatments of proper names. Strong criticisms will be advanced against Kripke＇s hypothesis of rigid-designator and, more deafly, against the consequent distinction between the epistemic and metaphysical level that Kripke proposes to explain identity assertions between proper names. Furthermore, I will argue, that, pace Kripke, Russellian treatment of proper names allows to capture all our semantic intuitions, and also those semantic interpretations which concern context-belief sentences. I will close the introduction by focusing on a criticism that Kripke rightly points out against an example that Russell proposes in his On Denoting. Section 2 will be devoted to Russellian solution： I will show that not only Russell＇s logical treatment of proper names allows to answer to Kripke＇s criticism to Russell＇s example, but also that such treatment can disambiguate and express all our semantic intuitions about Frege＇s puzzle sentence ＂Hesperus is Phosphorus.＂ ! will then show that, contrarily, Quinian solution （discussed in section 3） and Kripkian one （see section 4） are not satisfactory to capture our semantic knowledge about Frege＇s sentence. Furthermore, in section 5, I will focus on Kripke＇s distinction between epistemic and metaphysical level to deal with identity assertions between proper names, and I will logically show that such distinction is not plausible. In section 5, then, I will show that Russellian solution allows to explain context-belief sentences, contrarily to what Kripke thinks. In Conclusions, I will summarize what 1 have argued in the text.展开更多

Actually, we develop the Bessel collocation method by using the fractional derivative in the Caputo sense to obtain the approximate solutions of this model problem. By means of the fractional derivative in the Caputo sense, the collocation points, the Bessel functions of the first kind, the method transforms the model problem into a system of nonlinear algebraic equations. Numerical applications are given to demonstrate efficiency and accuracy of the method. In applications, the reliability of the scheme is shown by the error function based on the accuracy of the approximate solution.展开更多

文摘The author studied the existence of positive solutions of the delay logistic difference equation Δ y n=p ny n(1-y τ(n) ), n =0,1,2,.... where { p n } is a sequence of positive real numbers, { τ(n) } is a nondecreasing sequence of integers, τ(n)<n and lim n →∞ τ(n) =∞. A sufficient condition for the existence of positive solutions of the equation was given.
