this paper is a continuation of [uniformities and covering properties for partial frames (i)], in which we make use of the notion of a partial frame, which is a meet-semilattice in which certain designated subsets are required to have joins, and finite meets distribute over these. after presenting there our axiomatization of partial frames, which we call $sels$-frames, we added structure, in th...

Background: The aim of this study was to develop and implement a Monte Carlo framework for evaluation of patient specific out-of-field organ equivalent dose (OED). Materials and Methods: Dose calculations were performed using a Monte Carlo-based model of Oncor linac and tomographic phantoms. Monte Carlo simulations were performed using EGSnrc user codes. Dose measurements were performed using r...

We argue that in a nonlinear gravity theory (the Lagrangian being an arbitrary function of the curvature scalar R), which according to well–known results is dynamically equivalent to a self–gravitating scalar field in General Relativity, the true physical variables are exactly those which describe the equivalent general–relativistic model (these variables are known as Einstein frame). Whenever ...

High raised buildings are vulnerable to the lateral loads caused during natural calamities like earthquakes and cyclones. Lateral loads always affect the stability of structures. The shear walls, which are provided to resist these lateral forces, are often considered undesirable from utility point of view as they come in the way of vehicular movement in the parking area. Methods to evaluate the...

partial frames provide a rich context in which to do pointfree structured and unstructured topology. a small collection of axioms of an elementary nature allows one to do much traditional pointfree topology, both on the level of frames or locales, and that of uniform or metric frames. these axioms are sufficiently general to include as examples bounded distributive lattices, $sigma$-frames, $ka...

The fundamental notion of frame theory is redundancy. It is this property which makes frames invaluable in so many diverse areas of research in mathematics, computer science and engineering because it allows accurate reconstruction after transmission losses, quantization, the introduction of additive noise and a host of other problems. This issue also arises in a number of famous problems in pu...

Abstract: A finite element model is verified accurate enough to simulate the static test of one reinforced-concrete frame with specially shaped columns subjected to the loss of a ground corner column. As the frame sustained loads primarily depending on the beam resisting mechanism in the test, four related parameters, namely the height of beam section, rebar ratio of beam, rebar ratio of slab a...

The innationary scenarios suggested by the duality properties of string cosmol-ogy in the Brans-Dicke (or String) frame are shown to correspond to accelerated contraction (deeation) when Weyl-transformed to the Einstein frame. We point out that the basic virtues of innation (solving the atness and horizon problems, amplifying vacuum uctuations) have physically equivalent counterparts in the de-...

Unlike knowledge representation in modal logic, human tends to introduce new modalities on ad hoc basis in communication. Similar challenges arise from applications of distributed computing and hybrid systems that involve several time domains. This paper presents a parameterized approach for algebraic manipulation of modalities. Each pair of modalities of possibility and necessity is determined...
