Inhomogeneous multidimensional cosmological models with a higher dimensional space-time manifold M = M 0 × n i=1 M i (n ≥ 1) are investigated under dimensional reduction to a D 0-dimensional effective non-minimally coupled σ-model which generalizes the familiar Brans-Dicke model. It is argued that the Einstein frame should be considered as the physical one. The general prescription for the Eins...

The fourth Global Forum on Human Resources (HRH) for Health was held in Ireland November 2017. Its Dublin declaration mentions that strategic investments in the health workforce could contribute to sustainable and inclusive growth and are an imperative to shared prosperity. What is remarkable about the investment frame for health workforce development is that there is little debate about the ty...

The main purpose of this paper was to use a combination of Energy-based design method and whale algorithm (WOA), hereinafter referred to as E-WOA, to optimize steel moment frames and improve the seismic performance. In E-WOA, by properly estimating the seismic input energy and determining the optimal mechanism for the structure, steel frames are designed based on the energy balance method; acco...

This is one of two companion papers presenting new procedures for the efficient largedisplacement analysis of steel frames in the elasto-plastic range. Emphasis is given in this paper to the development and improvement of a plastic hinge approach utilizing the concept of adaptive mesh refinement. In the companion paper, such a concept is discussed in the context of a more accurate approach acco...

Large radar antennas are generally covered with radomes to protect them from extreme weather conditions and to enable their continuous precision operation without sacrificing their performance. The radomes are assembled from many panels connected together with metallic or dielectric beams because of their large size. The panels are made of thin membranes or type A sandwiches which are optimized...

‎By substituting the usual notion of open sets in a topological space $X$ with a suitable collection of maps from $X$ to a frame $L$, we introduce the notion of L-topological spaces. Then, we proceed to study the classical notions and properties of usual topological spaces to the newly defined mathematical notion. Our emphasis would be concentrated on the well understood classical connectedness...

In the past 20 years, AI researchers in knowledge representation (KR) have implemented over 50 frame knowledge representation systems (FRSs). KR researchers have explored a large space of alternative FRS designs. This paper surveys the FRS design space in search of design principles for FRSs. The FRS design space is de ned by the set of alternative features and capabilities | such as the repres...

Spatial prepositions are linguistic tools to exchange information about spatial location of objects. For instance “The book is over the table” indicates that the located object (LO) is somewhere “over” the reference object (RO). Assigning direction to space (selecting a reference frame) is a necessary precursor to understanding where the LO is located. Three experiments are reported which inves...

We study the differential forms over the frame bundle of the based loop space. They are stochastics in the sense that we put over this frame bundle a probability measure. In order to understand the curvatures phenomena which appear when we look at the Lie bracket of two horizontal vector fields, we impose some regularity assumptions over the kernels of the differential forms. This allows us to ...
