Is the hoopla over CPAF justified?

It may be worth asking whether all the hoopla over CPAF is justified. Our view is: yes, it is. As in any active scientific area, not every proposal regarding CPAF function has held up. The recent developments are very encouraging: we now have a much better idea of what CPAF can do, but also what it does not do. Our current knowledge can be summarized as follows: Chlamydiae produce a potent prot...

HIERARCHICAL COMPUTATION OF HERMITE SPHERICAL INTERPOLANT

In this paper, we propose to extend the hierarchical bivariateHermite Interpolant to the spherical case. Let $T$ be an arbitraryspherical triangle of the unit sphere $S$ and  let $u$ be a functiondefined over the triangle $T$. For $kin mathbb{N}$, we consider aHermite spherical Interpolant problem $H_k$ defined by some datascheme $mathcal{D}_k(u)$ and which admits a unique solution $p_k$in the ...

Hierarchical HLA: Mapping Hierarchical Model Structure into Hierarchical Federation

The High Level Architecture (HLA) defines a federation as a group of simulators. The HLA does not define relations between federations. This makes any complicated structure of a system flat. The absence of hierarchy may bring several issues related to data exchange, security and reusability. The paper proposes the Hierarchical HLA that defines hierarchical relationship between federations. The ...

Fuzzy Hierarchical Location-Allocation Models for Congested Systems

There exist various service systems that have hierarchical structure. In hierarchical service networks, facilities at different levels provide different types of services. For example, in health care systems, general centers provide low-level services such as primary health care services, while the specialized hospitals provide high-level services. Because of demand congestion in service networ...
