We introduce the one-way radiative transfer equation (RTE) for modeling the transmission of a light beam incident normally on a slab composed of a uniform forward-peaked scattering medium. Unlike the RTE, which is formulated as a boundary value problem, the one-way RTE is formulated as an initial value problem. Consequently, the one-way RTE is much easier to solve. We discuss the relation of th...

Standard fire resistance tests and post-fire on residual mechanical properties were carried out two four-edge simply supported reinforced truss concrete two-way composite slabs with wide seam splicing (“integral seam”) close (“separated seam”), the effects of different forms during after exposure to high temperatures explored. The results indicate that there are significant differences in terms...

It is shown that for any class C closed under linear-time reductions, the complete sets for C under sublogarithmic reductions are also complete under 2DFA reductions, and thus are isomorphic under first-order reductions.

On every n-long input, every two-way finite automaton (fa) can reverse its head O(n) times before halting. A fawith few reversals is an automaton where this number is only o(n). For every h, we exhibit a language that requires Ω(2) states on every deterministic fa with few reversals, but only h states on a nondeterministic fa with few reversals.

Based on the long-span slab in an assembled building project, ABAQUS is used to simulate mechanical properties and failure modes of under condition whole span cast-in-place two-way rebar truss composite (hereinafter referred as slab) with different splicing methods, which slabs adopt fixed support loads are uniformly distributed load. The finite element simulation results show that integrity no...

Structural members with low-flexural stiffness, such as slabs, are more susceptible to impulsive loadings induced by falling machines/tools during construction and installation, also from rolling boulders/rocks triggered wind/earthquake, especially in mountainous areas. The impact resistance of reinforced concrete (RC) slabs supported on two opposite edges (often called the one-way slab) all fo...

In this paper, we show how the study of two-way automata on words may relevantly be extended to the study of two-way automata on one-dimensional overlapping tiles that generalize finite words. Indeed, over tiles, languages recognizable by finite two-way automata (resp. multi-pebble automata) coincide with languages definable by Kleene’s (resp. Kleene’s extended) regular expressions. As an immed...

Given a set of points in a Hilbert space that can be separated from the origin. The slab support vector machine (slab SVM) is an optimization problem that aims at finding a slab (two parallel hyperplanes whose distance—the slab width—is essentially fixed) that encloses the points and is maximally separated from the origin. Extreme cases of the slab SVM include the smallest enclosing ball proble...

At present, reducing subgrade settlement of soft soil foundation is a key problem in high-speed railway construction. Pile-slab structure is a widely-utilized form of foundation structure to reduce the subgrade settlement in China. In order to save the engineering cost for high-speed railway construction in developing countries, the author developed a pile-slab structure and named it as the new...

This study was an attempt to investigate what metacognitive strategies are specifically employed by English learners when it comes to different speaking task types.60 students at advanced level (female) were randomly selected and given an OPT as a test of homogeneity. They were assigned to experimental and control groups. The MS questionnaire (Oxford, 1990) was also administered to see what MS ...
