Mining causality knowledge will induce knowledge of reasoning beneficial for our daily use in diagnosis. This framework is for discovering causality existing between causative antecedent and effective consequent discourse units. There are two main problems in causality extraction; causeeffect identification and cause-effect boundary determination. The causeeffect identification problem can be s...

The ignition temperature of nitrogen-diluted dimethyl ether (DME) by heated air in counterflow was experimentally determined for DME concentration from 5.9% to 30%, system pressure from 1.5 to 3.0 atm, and pressure-weighted strain rate from 110 to 170 s . These experimental data were compared with two mechanisms that were, respectively, available in 1998 and 2003, with the latter being a substa...

In the midst of Covid-19 pandemic, there is a need to understand teacher choices for format teaching children at start 2020-2021 academic year. The aim study was assess in school versus virtual home learning during 2019–2020 year and factorsassociated with choice. Participants were 100 samples teachers on elementary, junior high City Jombang. Teachers are asked fill out an online survey about i...

The four most important factors that govern the return stroke evolution can be identified as: (i) electric field due to charge distributed along the channel, (ii) transient enhancement of conductance by several orders at the bridging regime (iii) the non-linear increase in channel conductance at the propagating current front and (iv) the associated dynamic electromagnetic field which support th...

A classical construction associates to a transient random walk on discrete group $$\Gamma $$ compact -space $$\partial _M \Gamma known as the Martin boundary. The resulting crossed product $$C^*$$ -algebra $$C(\partial ) \rtimes _r comes equipped with one-parameter of automorphisms given by kernels that define In this paper we study KMS states for flow and obtain complete description when Poiss...

This study makes use of a very long time series the S&P Composite Index, checking once more that rates return benefit from aggregational normality. It performs unit root tests as well elementary statistical take advantage finds mean blur is not consistent with hypothesis random walk constant parameters, because means annual real linear can be estimated usual. gives further evidence on Index...

Lamé's formulas for the eigenvalues and eigenfunctions of the Laplacian on an equilateral triangle under Dirichlet and Neumann boundary conditions are herein extended to the Robin boundary condition. They are shown to form a complete orthonormal system. Various properties of the spectrum and modal functions are explored. 1. Introduction. The eigenstructure of the Laplacian on an equilateral tri...

The word “boundary,” as found in standard English-language dictionaries, means “that which bounds, divides, or separates,” or “something that indicates a border or limit.” In its generally accepted meaning, the concept of boundary is used to describe the physical landscape at various levels of granularity. In some cases, it may be used to describe the shape and size of individual plots; in othe...

We are accustomed to the idea that while the boundary between two regions is likely to consist of arcs, the points that are in the boundary of three or more regions are intuitively expected to be isolated. In the United States, there is only one point that is in the boundary of four states. In dynamical systems, the boundaries are more complicated. Topologists discovered that it is possible to ...
