A general approach is proposed for the accurate and efficient computation of the characteristic parameters of coplanar waveguides having electrodes of complex cross-section on multi-layered, planar or non-planar substrates, as presently considered for high-speed (semiconductor or LiNbO3) electrooptic modulators. The approach is based on the coupling of quasi-TEM finite element method with numer...

Given an uncountable regular cardinal κ, a partial order is κstationarily layered if the collection of regular suborders of P of cardinality less than κ is stationary in Pκ(P). We show that weak compactness can be characterized by this property of partial orders by proving that an uncountable regular cardinal κ is weakly compact if and only if every partial order satisfying the κ-chain conditio...

Sorption-desorption of two different hydrophobic fungicides, penconazole and metalaxyl, by a series of clay minerals layered and non-layered (montmorillonite, illite, kaolinite, muscovite, sepiolite and palygorskite) modified with the two-chain cationic surfactant, dihexadecyldimetylammonium (DHDDMA) was studied by first time in this work. DHDDMA-clays showed a good capacity to sorb both fungic...

Magnetic properties of layered high temperature superconductors with a weak interlayer coupling in the region of the critical fluctuations are investigated in the framework of the Ginzburg–Landau approach. The sample magnetization is calculated within a perturbative approach to the second order in the interlayer coupling constant. The first order correction can be incorporated into the non-inte...

Ž . Gabbroic sills intruding dunite in the crust–mantle transition zone MTZ of the Oman ophiolite have textures and compositions very similar to those in modally layered gabbros that form the lower part of the gabbro section in the ophiolite, and different from those in non-layered gabbros near the dike–gabbro transition. The presence of gabbroic sills in the MTZ indicates that modally layered ...

Because of diversity, complexity and poor information about non-layered orebody, it is difficult to be accurately described by regular geometry model. Mining engineers couldn’t accurately estimate the space distribution law of orebody's grade, quality and the total reserve according to the traditional 2-dementional (2D)graphics. So it is necessary to accurately establish non-layered orebody mod...

this paper investigates the lateral vibration of single-layered graphene sheets based on a new theory called doublet mechanics with a length scale parameter. after a brief reviewing of doublet mechanics fundamentals, a sixth order partial differential equation that governs the lateral vibration of single-layered graphene sheets is derived. using doublet mechanics, the relation between natural f...

We describe a multi-layered behavior based agent architecture which has been applied to the Robocup domain. Upper layers are used to control the activation and priority of behaviors in layers below, and only the lowest layer interacts directly with the server. The layered approach seems to simplify behavior management. In particular it provides an approach for implementing high level strategic ...

The classical view of artificial intelligence (AI) is tied down by a number of problems. These problems indicate that it might be fruitful to approach AI applications, including spoken dialogue systems, in an alternative way. This paper overviews current attempts to apply the idea of layered behavior-based architectures in dialogue system development. It is concluded that there are both theoret...

The goal of this paper is to discuss how adaptive search systems should be evaluated. We argue that a state-of-the art evaluation of adaptive search systems should follow a “layered evaluation” approach. To support and explain this argument we describe how layered approach was applied to evaluation of adaptive search component of Knowledge Sea II system that is powered by a social navigation su...
