  • Started upon it discovery by Wright et al in 1973, studies on the solid polymer electrolyte are being carried out vigorously. So, models of Li-polymer battery have been developed through R-L-C components combination and P-spice functional block in this paper. The impedance characteristics of Li-polymer battery with R-L-C components are presented. Simulation results using P-spice functional model are compared with measured charge/discharge characteristics.

  • The recent research investigates the generalization of Bessel function in different forms as its usefulness in various fields of applied sciences. In this paper, we introduce a new modified form of k-Bessel functions called the generalized modified k-Bessel functions and established some of its properties.

  • This paper deals with the solutions of linear inhomogeneous time-fractional partial differential equations in applied mathematics and fluid mechanics. The fractional derivatives are described in the Caputo sense. The fractional Green function method is used to obtain solutions for time-fractional wave equation, linearized time-fractional Burgers equation, and linear time-fractional KdV equation. The new approach introduces a promising tool for solving fractional partial differential equations.

  • 최근의 이상 기후현상은 수목의 개화시기 변화를 가져오고 나아가 수목 피해를 초래하기도 한다. 산림의 쇠퇴에 대하여는 국내외적으로 많은 연구가 이루어져 있으며(Krause et al, 1986; Kitajima, 1988) 이러한 쇠퇴림은 수분스트레스에 민감할 것으로 보고되었다(Hauhs and Wright, 1986; Ulrich, 1990).(중략)

  • 7세의 홀스타인 암소에서 엽록소가 없는 Prototheca에 의한 만성적인 진행성 유방 염의 발생에 대해 보고한다. 유방염 우유로 만든 습윤표본에서 명확한 세포벽과 내생포자를 갖고 있는 구형 내지 난원형의 병원체가 직접 관찰되었고, Sabouraud배지에서의 순수배양물 에 대해 Wright염색 및 PHOL염색을 했을 때 algae가 증명되었으며, nutrient배지에서 세균 이 중식하지 않아서 Prototheca가 유방염의 원인으로 제시되었다. 이 병원체는 자연상태에서 는 사물기생성이지만 감염원은 확실하지 않았다. algae와 진균의 형태학적인 연구를 하는데 있어서 PHOL염색액을 광범위하게 응용할 수 있음을 제시하였다. Prototheca의 ecology와 병원성을 규명하기 위해 더 많은 연구가 이루어져야 될 것으로 생각된다.

  • Kiefer (1961) studied asymptotic behavior of empirical distribution using the law of the iterated logarithm. Robertson and Wright (1974a) discussed whether this type of result would hold for a maximum likelihood estimator of a stochastically ordered distribution function; however, we show that this cannot be achieved. We provide only a partial answer to this problem. The result is applicable to both estimation and testing problems under the restriction of stochastic ordering.
