Polymer composites with carbon nanotubes have recently been investigated for improving certain properties i.e., electrical, optical and mechanical properties[1-3]. Kymakis et. al. have reported the electrical and optical properties of single wall carbon nanotube-poly(3-octylthiophene) composites[4]. Polyurethane dissolved in dimethylformanide (DMF) were electrospun by Demir et. al.[5]. (omitted)

We consider the modulus-based successive overrelaxation method for the linear complementarity problems from the discretization of Black-Scholes American options model. The $H_+$-matrix property of the system matrix discretized from American option pricing which guarantees the convergence of the proposed method for the linear complementarity problem is analyzed. Numerical experiments confirm the theoretical analysis, and further show that the modulus-based successive overrelaxation method is superior to the classical projected successive overrelaxation method with optimal parameter.

This paper is devoted to investigate the singular directions of meromorphic functions in some angular domains. We will confirm the existence of Hayman T directions in some angular domains. This is a continuous work of Yang [8] and Zheng [10].

DRM(Distal Right Management)은 컨텐츠의 불법 사용을 방지하여 저작권을 보호하고, 컨턴츠의 생성·유통·사용 관리 등에 필요한 모든 처리를 지원하는 종합 솔루션이다. DRM 체계에서 사용자(customer)는 컨텐츠를 정당하게 사용하기 위해서 클리어링하우스(clrearinghouse)로부터 라이센스를 발급받아야 한다. 일반적으로 라이센스(license)는 사용자의 공개키로 암호화된다. 그래서 사용자의 계산적 부담이 크다. 특히 무선 DRM 환경이라면, 사용자의 부담은 더 클 것이다. 따라서 본 논문은 익명성을 갖는 제안 1회용 대리서명 기법과 Y.Zheng의 Singcryption 기법을 적용하여 사용자의 계산량을 줄이고, 익명성을 갖는 효율적인 라이센스 다운로드 방식을 제안한다.

Some errors in literatures are pointed out and corrected. A generalization of Ostrowski type inequalities for functions whose derivatives in absolute value are s-convex in the second sense is established. Special cases are discussed.

In this paper, the problem on periodic solutions of the bidirectional associative memory neural networks with both periodic coefficients and periodic time-varying delays is discussed. By using degree theory, inequality technique and Lyapunov functional, we establish the existence, uniqueness, and global asymptotic stability of a periodic solution. The obtained results of stability are less restrictive than previously known criteria, and the hypotheses for the boundedness and monotonicity on the activation functions are removed.
