In this paper, a numerical solution is presented for one-dimensional unsaturated flows in the subsurface. Water flow in the subsurface, however, is highly nonlinear and in most cases, exact analytical solutions are impossible. The method of reference-operators has been used to formulate a discrete model of the continuum physical system. Many of the standard finite difference methods and also th...
A wide increment of the object-oriented diffusion has been registered. This is accompanied by the needs of metrics and tools for assessing class reusability, maintainability, complexity, etc. Metrics have to produce confident results and have to be continuously revalidated on the basis of specific purpose on their adoption. Tools for system assessment must be capable of satisfying the needs of ...
We present evidence for a 0 (1450) decaying to KK in pp annihilation at rest in liquid hydrogen in the nal state K L K. This reaction is important for the study of the KK decay mode of scalar resonances, in particular the isovectors a 0 (980) and a 0 (1450). The determination of the a 0 (1450) production also xes the KK coupling of the isoscalar f 0 (1500). We
Introduction In the scientific world it is recognized that high levels of collaboration, but particularly international scientific collaborations, lead to increase in citations, a better quality of the papers published, and a greater productivity of the authors (Leimu & Koricheva, 2005; Hsu & Huang, 2010). However this citation increment may vary across nations. For various reasons, there might...
. We combine the creation and annihilation operators of a scalar field in Minkowski spacetime to obtain the generators of the SU(1,1). We show that the transformation between Minkowski and Rindler vacua can be represented by (pseudo)rotation in the space of the SU(1,1) group. The root of this fact originates from the coordinate transformation between Minkowski and Rindler manifolds that can als...
In this paper, some properties of pre-monotone operators are proved. It is shown that in a reflexive Banach space, a full domain multivalued $sigma$-monotone operator with sequentially norm$times$weak$^*$ closed graph is norm$times$weak$^*$ upper semicontinuous. The notion of $sigma$-convexity is introduced and the relations between the $sigma$-monotonicity and $sigma$-convexity is i...
