In this paper, we introduce another statement of a digital $(k_{0}, k_{1})-homeomorphism$ which is suitable for an approach to write an efficient algorithm for discriminating digital images with respect to the digital $(k_{0}, k_{1})-homeomorphism$.

Knowledge management (KM) is emerging as a robust management mechanism with which an organization can remain highly intelligent and competitive in a turbulent market. Organization knowledge is at the heart of KM success. As a vehicle of acquiring organizational knowledge in a distributed decision-making environment, we applied a fuzzy cognitive map (FMM) technique and proved its effectiveness in a distributed knowledge management environment. Our approach was applied to the financial statement analysis problem, yielding a robust result.

The spectral content of ground displacement of the 10 largest last California earthquakes is studied. Specifically, the power spectral density function of the critical horizontal-component record of the closest-to-epicenter station is analyzed in each case. The results permit to state that horizontal ground displacement is a narrow-band process. This fact was previously noticed while trying to solve the large-base-displacement problem in isolated structures and it was fundamental in the solution of this issue; however, these preliminary results were limited in number to enable a statement like the foregoing one. Thus, the broader results presented herein were necessary.

Reliability calculation of a system is frequently required in industrial, military, and everyday life situations. For such a calculation, it is necessary to specify the configuration of components and subsystems, the failure mode of each component, and the states in which the system is classified as failed. In this paper, we are primary interested in the time to the first failure of a system. And we discuss failure probability of coherent system under various condition, especially focus on probability calculation of subsystem failure before system failure used by Bayes formula. Problem statement and general applications illustrated by several examples.

PP/ST의 보안환경 개발은 정보보호제품에 대하여 이력서라고 할 수 있다. 이에 기존의 위협문장 생성모델을 개선하여 속성기반 위협문장 생성모델을 제시한다. 본 모델은 PKB의 속성들을 이용하여 위협문장 생성시 각 항목(주어, 목적어, 동기, 동사, 결과)에 속성을 추가·확장하여, 문장이 컨텐츠 뿐만 아니라 특수성을 갖게 된다. 본 논문에서 제시된 모델은 PP/ST 개발시 위헙문장을 생성할 때 활용될 수 있다.

Recent work by Gwena and Teixidor i Bigas provides a characteristic-free proof of a part of a previous theorem by one of us, under a stronger numerical assumption. By using an intermediate result from the mentioned manuscript, here we present a simpler, characteristic-free proof of the whole original statement.

Integration is an important intellectual ability to reconfigure several separated elements into one unified form and to concisely and categorically express them. In this paper, we classify the types of integration in C language, and propose a systematic and incremental method to transform to better code based on the integration types. This transformation method could also be used as a means to improve integrated thinking and efficiently learn C language, and will improve development ability in C programming or other language programming.

In this paper, we find all the prime numbers p that satisfy the following statement. If a positive integer k is a divisor of p - 1, then there is a sequence consisting of all k-th power residues modulo p, satisfying the recurrence equation of the Fibonacci sequence modulo p.

The target of this article is to modify the algorithm given by Fang and Huang [6]. The rate of convergence of our algorithm is faster than that of Fang and Huang [6]. A numerical example is given to justify our statement.
