  • This paper presents a method for Identification of a continuous time linear system parameters. We take the plant driven by percitently exciting input. To express the integral functions in terms of measured periodic output data. We use the Walsh function based on cal-sal functions. The linear algebraic equations for parameter identification is obtained. The present method Is simple and computationally advantageous.

  • The disinfection effects of Trichloro isocyanuric acid (TICA) and Calcium hypochlorite (Cal-hypo) against E. coli' in aqueous suspension were compared at various concentrations of disinfectants as well as exposure times. When E, coil($^{\sim}10^7$ CFU/ml) were exposed by TICA and Cal-hypo (12 ppm each), 90% of the initial cells were reduced in 4 sec and 390 sec, respectively. Although Cal-hypo lost its disinfection capability in about 1 hr under the sun light, TICA maintained its effect up to 6 hrs. This comparative studies clearly demonstrate that TICA is more effective than Cal-hypo in terms of sterilizing E. coli as well as maintaining the disinfection effects.

  • Given vectors x and y in a Hilbert space, an interpolating operator is a bounded operator T such that Tx=y. In this paper the following is proved: Let $\cal{L}$ be a subspace lattice on a Hilbert space $\cal{H}$. Let x and y be vectors in $\cal{H}$ and let $P_x$, be the projection onto sp(x). If $P_xE=EP_x$ for each $ E \in \cal{L}$ then the following are equivalent. (1) There exists an operator A in Alg(equation omitted) such that Ax=y, Af = 0 for all f in ($sp(x)^\perp$) and $A=-A^\ast$. (2) (equation omitted)

  • In this paper tried the estimation of parameter using of Cal-Sal functions. System equation given by the linear differential equation is converted into the integral equation, operation matrix for integral of Cal-Sal functions is used to find the estimation of parameter on the given system. Converting linear differential equation to linear algebraic equation, the method presented here computing time and required memory size can be reduced. Therefore real time data process can be possible.

  • 21세기 제조기업의 경쟁력 향상을 위한 당면 과제로 대두되고 있는 CALS는 선진국을 중심으로 새로운 정보화 수단으로 확산되고 있다. CALS는 기업의 모든 생산활동을 광속으로 연결하는 통합정보시스템이며, ERP는 CALS 구현에 있어서 핵심부분으로 각 기업은 MRP를 포함한 여러 경영관리 시스템이 독립적으로 운영되는데 따른 프로세스간 정보의 단절을 배제하기 위해 수요 예측에서부터 생산, 출하에 이르기까지 기업활동 전반을 통합된 시스템 내에서 수행할 수 있는 생산정보시스템이다. 그러나 일반적으로 ERP시스템 구축에는 많은 자본이 소요되기 때문에 기업은 자체 개발 보다는 전사적인 관리기능을 패키지 형태로 통합한 ERP를 도입하는 실정이며 국내에서도 ERP패키지 개발을 진행중이나 실용화되기에는 다소 시간이 걸릴 것으로 생각된다. 본 연구에서는 CIM과 CALS의 개념, CIM과 CALS의 관계, ERP의 개념을 설명하고 마지막으로 CALS 구현을 위한 ERP모형을 제시하고자 한다.

  • We first study the generalized Fourier-Gauss transforms of functionals defined on the complexification $\cal{B}_C$ of an abstract Wiener space ($\cal{H}$, $\cal{B}$, ${\nu}$). Secondly, we introduce a new class of convolution products of functionals defined on $\cal{B}_C$ and study several properties of the convolutions. Then we study various relations among the first variation the convolutions, and the generalized Fourier-Gauss transforms.

  • In this paper, we de ne an $L_p$ analytic generalized Fourier Feynman transform and a convolution product of functionals in a Ba-nach algebra $\cal{F}$($C_{a,b}$[0, T]) which is called the Fresnel type class, and in more general class $\cal{F}_{A_1;A_2}$ of functionals de ned on general functio space $C_{a,b}$[0, T] rather than on classical Wiener space. Also we obtain some relationships between the $L_p$ analytic generalized Fourier-Feynman transform and convolution product for functionals in $\cal{F}$($C_{a,b}$[0, T]) and in $\cal{F}_{A_1,A_2}$.

  • 최근 소비자의 요구가 다양해짐에 따라 이에 대응하기 위한 경영 전략들 역시 다양해지고 있다. 이중 CALS는 비지니스 리엔지니어링(Business Process Reengineering), 동시공학(Concurrent Engineering), CIM(Computer Integrated Manufacturing)등의 여타 경영혁신 기법들을 모두 수용하면서도, 그 구현에 있어서 인터넷, 수퍼 하이웨이, 정보기술의 표준, 생산자동화등과 같은 구체적인 핵심정보기술의 지원을 받은 새로운 경영전략이다. CALS는 다양한 기술과 전략을 포함하고 있으므로, 이들간의 통합된 구도를 관리할 필요가 있으며, 제품의 전 수명주기를 그 대상으로 하므로 생산공학, 품질공학, 인간공학, 경영공학, 정보공학, 물류공학등의 산업공학적 관점에서 그 효율을 극대화하려는 노력이 절실히 요구된다. 본 논문에서는 CALS에 있어서의 산업공학의 역할을 주지하며, 이에 관련된 연구 방향을 제시하고자 한다.

  • In this paper, we establish general stratawise higher jet evaluation transversality of J-holomorphic curves for a generic choice of almost complex structures J (tame to a given symplectic manifold (M, $\omega$)). Using this transversality result, we prove that there exists a subset $\cal{J}^{ram}_{\omega}\;{\subset}\;\cal{J}_{\omega}$ of second category such that for every $J\;{\in}\;\cal{J}^{ram}_{\omega}$, the dimension of the moduli space of (somewhere injective) J-holomorphic curves with a given ramication prole goes down by 2n or 2(n - 1) depending on whether the ramication degree goes up by one or a new ramication point is created. We also derive that for each $J\;{\in}\;\cal{J}^{ram}_{\omega}$ there are only a finite number of ramication profiles of J-holomorphic curves in a given homology class $\beta\;{\in}\;H_2$(M; $\mathbb{Z}$) and provide an explicit upper bound on the number of ramication proles in terms of $c_1(\beta)$ and the genus g of the domain surface.
