Characteristic boundary conditions are discussed in conjunction with a flux-difference splitting formulation as modified from Roe's linearization. Details of how one can implement the characteristic boundary conditions which are compatible with the discrete formulation at interior points are given for different types of boundaries including subsonic outflow and adiabatic wall. The latter conditions are demonstrated through computation of supersonic ogive-cylinder flow at high angle of attack and the computed wall pressure distribution is compared with experiment.

Existence of common fixed points for generalized S-nonexpansive subcompatible mappings in convex metric spaces have been obtained. Invariant approximation results have also been derived by its application. These results extend and generalize various known results in the literature with the aid of more general class of noncommuting mappings.

In the present paper, we utilize the notion of converse commuting mappings due to L$\ddot{u}$ [On common fixed points for converse commuting self-maps on a metric spaces, Acta. Anal. Funct. Appl. 4(3) (2002), 226-228] and prove a common fixed point theorem in Menger space using an implicit relation. We also give an illustrative example to support our main result.

In this paper we prove certain coupled coincidence point and coupled common fixed point results in partially ordered metric spaces for a pair of compatible mappings which satisfy certain rational inequality. The results are supported with two examples.

To develop operation scenarios of KT-2 tokamak, 3 operation modes(OH, high ${\beta}$ and high bootstrap) deduced from zero dimensional steady-state power balance are examined with TSC(Tokamak Simulation Code) time-dependent transport .ode. Plasma profiles are evaluated self consistently during simulations and plasma shapes are maintained by feedback control on PF coil currents. Simulations show operation modes which are typical of KT-2 expected discharges are compatible with the KT-2 PF system design specifications[1].

Leveling colostomy with a frozen-section biopsy in a Hirschsprung's disease is an important factor for a successful procedure. Two neonatal cases of Hirschsprung's disease in the descending colon are reported. In both cases, loop ileostomy was established because of the unavailability of frozen-section biopsy on an emergency basis. At the time of definitive procedure of the first case, transition zone at the splenic flexure was noted and was compatible with the frozen section biopsy. In the second case, an unexpected longer resection at a higher level than transition zone was required because of the poor vascularity after dissection. In conclusion, a leveling colostomy should be selected as a choice in long-segment Hirschsprung's disease. Confirming preservation of the marginal artery of Drummond is particularly important in case of Hirschsprung's disease in the descending colon.

한반도 상공의 오존층 및 대기층 참사를 임무로 하는 과학관측로케트(KSR-420s)는 비행중에 갖게되는 온도, 응력, 가속도, 압력, 자세, Ranging 등의 비행상태 정보와 오존층, 전리층, X-선등의 관측데이타를 지상으로 전송한다. 본 연구에서는 KSR-420s의 비행궤도를 추적하면서 전송되어 오는 신호를 수신 처리하기위한 텔레메트리 지상시스템을 설계하였다.

Let (X,S,$\mu$) be a measure space and M be the vector space of all real valued S-measurable functions defined on (X,S,$\mu$). For $E\;{\in}\;S$ with $\mu(E)\;<\;{\infty}$, $d_E$ is a pseudometric on M. With the notion of D = {$d_E$\mid$E\;{\in}\;S,\mu(E)\;<\;{\infty}$}, in this paper we investigate some topological structure T of M. Indeed, we shall show that it is possible to define a complete invariant metric on M which is compatible with the topology T on M.

In this paper, we use He's polynomials for solving higher order integro differential equations (IDES) by converting them to an equivalent system of integral equations. The He's polynomials which are easier to calculate and are compatible to Adomian's polynomials are found by using homotopy perturbation method. The analytical results of the equations have been obtained in terms of convergent series with easily computable components. Several examples are given to verify the reliability and efficiency of the proposed method.
