Remote sensing data processing and analysis system can be developed based on the Grid Coverage Specification and this kind of system is also can be easily interoperate with GIS systems conforming OpenGIS specification. This paper proposes a method to implement easily and quickly the new grid coverages that provide new operations, or services, by reusing the existing grid coverage components, which is based on the fact that the pipeline constructed by grid coverages can be represented in one grid coverage. This method complements easily the deficiency of the existing grid coverage components and enables quick implementation of the new grid coverage that provides complex processing operations.

In this Paper, it was designed the GA-fuzzy controller of a Thyristor Controlled Series Capacitor(TCSC) for enhancement of power system stability. The newly designed controller of TCSC was designed to overcome the nonlinearity such as operating point change of power system as well as to respond to disturbances as uncertainties of line parameters and line fault. So, fuzzy controller by intelligent control theory was used for it. And the fuzzy controller was optimized from a genetic algorithm for complements the demerit such as the difficulty of the component selection of fuzzy controller namely. scaling factor. membership function and control rules. Nonlinear simulation results show that the proposed control technique is superior to conventional PSS in dynamic responses over the wide range of operating conditions and is convinced robustness and reliableness in view of structure.

This paper attempts to provide an alternative analysis involving categorical issues related to English gerunds. Especially, this paper rejects Maulof's approach that creates a new syntactic category gerund by mixing nominal and verbal categories. This paper identifies two syntactic structures in English gerunds: nominal gerunds and verbal gerunds. This distinction is based on syntactic and semantic characteristics of each type and is intended to account for the external distribution and endocentricity of the construction. Treating verbal gerunds syntactically as verbal categories, this paper proposes that English verbal gerunds act like other verbal categories such as infinitives whereas nominal gerunds behaves much like derived nominals. This paper proposes a few lexical rules that can take care of the two types of gerunds. The proposal can be extended to prepositional complements as well as sentential subject positions. This proposal not only resolves the issues involving distributional properties of the gerund construction but also captures syntactic parallelism observable between gerunds and other verbal constructions in English.

I. Objectives It is reported that there are complements and immunogloblins in serum from dental pulp in dentinal tubules, and it is thought that dental caries bacteria is opsonized by these serum ingredients, and it is presented by dendritic cells(DCs) in dental pulp. So, we examined whether a maturational difference of DCs occured when S. mutans was opsonized. II. Materials and Methods PBMC was divided from normal human peripheral blood and collected CD14 positive cells by magnetic beads system. Adherent cells were incubated in 5% FCS-RPMI medium included GM-CSF, IL-4 for seven days.(omitted)

For half a century, PMM(Project Management Model) continually has been advanced by many researchers and managers. Especially, the model for civil and construct engineering has now high maturity, but the model for IT engineering has not acceptable maturity. PMI(Project Management Institute) provides the knowledge of protect management for general purpose, it is not adequate for IT prefect management without complements. In this paper, we propose IT project management model based the knowledge of PMI using UML. IT project management model provides not only functions for project planning, budgeting, design and Implement, but also the knowledge for managing IT protect efficiently. We use uses case diagrams to describe the details of the model. We expect the model to be used in management of IT project efficiently in public sector.

본 논문에서는 RSA 암호 알고리즘의 핵심 계산 과정인 모듈로 곱셈 연산의 효율적인 하드웨어 구현을 위해 새로운 알고리즘과 하드웨어 구조를 제시한다. 기존의 몽고메리 알고리즘이 LSB 우선 방법을 사용한 것과는 달리 여기서는 MSB 우선 방법을 사용하였으며, RSA 암호 시스템에서 키가 일정 기간 동안 변하지 않고 유지된다는 점에 착안해 계수(Modulus)에 대한 보수(Complements)를 미리 계산해 놓고 이를 이용하여 모듈로 감소 처리를 간단히 덧셈으로 치환하도록 하였다. 보수들을 저장할 몇 개의 레지스터와 그들 중 하나를 선택하기 위한 간단한 멀티플렉서(Multiplexer)만을 추가함으로써 몽고메리 알고리즘이 안고 있는 홀수 계수 조건과 사후 연산이라는 번거로움을 없앨 수 있다. 본 논문에서 제안하는 알고리즘은 하드웨어 복잡도가 몽고메리 알고리즘과 비슷하며 그 내부 계산 구조를 보여주는 DG(Dependence Graph)의 지역 연결성 (Local Connection), 모듈성(Modularity), 데이터의 규칙적 종속성 (Regular Data Dependency)등으로 인한 실시간 고속 처리를 위한 VLSI 구현에 적합하다.

The purpose of this paper is to optimize the number of source places required for the unique representation of the destination using the tools of graph theory. A subset S of vertices of a graph G is called a rational resolving set of G if for each pair u, v ∈ V - S, there is a vertex s ∈ S such that d(u/s) ≠ d(v/s), where d(x/s) denotes the mean of the distances from the vertex s to all those y ∈ N[x]. A rational resolving set is called minimal rational resolving set if no proper subset of it is a rational resolving set. In this paper we study varieties of minimal rational resolving sets defined on the basis of its complements and compute the minimum and maximum cardinality of such sets, respectively called as lower and upper rational metric dimensions for power of a path P_n analysing various possibilities.

We find all P-resolutions of quotient surface singularities (especially, tetrahedral, octahedral, and icosahedral singularities) together with their dual graphs, which reproduces (a corrected version of) Jan Steven's list [Manuscripta Math. 1993] of the numbers of P-resolutions of each singularities. We then compute the dimensions and Milnor numbers of the corresponding irreducible components of the reduced base spaces of versal deformations of each singularities. Furthermore we realize Milnor fibers as complements of certain divisors (depending only on the singularities) in rational surfaces via the semi-stable minimal model program for 3-folds. Then we compare Milnor fibers with minimal symplectic fillings, where the latter are classified by Bhupal and Ono [Nagoya Math. J. 2012]. As an application, we show that there are 6 pairs of entries in the list of Bhupal and Ono [Nagoya Math. J. 2012] such that two entries in each pairs represent diffeomorphic minimal symplectic fillings.

We study the recovery results of ${\ell}_p$-constrained compressive sensing (CS) with $p{\geq}1$ via robust width property and determine conditions on the number of measurements for standard Gaussian matrices under which the property holds with high probability. Our paper extends the existing results in Cahill and Mixon from ${\ell}_2$-constrained CS to ${\ell}_p$-constrained case with $p{\geq}1$ and complements the recovery analysis for robust CS with ${\ell}_p$ loss function.

Ricci curvature for locally finite graphs, as proposed by Lin, Lu and Yau, provides a useful isomorphism invariant. A Matching Condition was introduced as a key tool for computation of this Ricci curvature. The scope of the Matching Condition is quite broad, but it does not cover all cases. Thus the current paper introduces extended versions of the Matching Condition, and applies them to the computation of the Ricci curvature of a class of circulants determined by certain number-theoretic data. The classical Matching Condition is also applied to determine the Ricci curvature for other families of circulants, along with Cayley graphs of abelian groups that are generated by the complements of (unions of) subgroups.
