Microwave heating of waste results in chemical breakdown that can lead to conversion mixed materials fuel. Heating mixtures with microwave energy rather than incineration faster and therefore be more efficient. Here we address small volumes food widely differing temperature-dependent electrical properties. Uniform is accomplished mode mixing within a loaded cavity by spatial power combining sol...

Gian-Carlo Rota believed that mathematics is a unity, in the deep sense that the same themes recur – as analogies – in its many branches. Thus, it comes as no surprise that Rota perceived combinatorial themes in continuous mathematics (as well as the other way around). In the preface to his book Introduction to Geometric Probability [10], written with the first author, Rota suggested only partl...

obesity as a common health risk is increasing all over the world. the aim of this study was evaluation of standing and sitting positions on spirometric values in obese asthmatic patients, in comparison with normal obese subjects. the study included 49 obese asthmatic patients with mean age of 42.63 years and body mass index of 36.06 kg/m 2 , and 51 control obese normal subjects with mean age of...

We calculate the volumes of a large class of Einstein manifolds, namely Sasaki-Einstein manifolds which are the bases of Ricci-flat affine cones described by polynomial embedding relations in C. These volumes are important because they allow us to extend and test the AdS/CFT correspondence. We use these volumes to extend the central charge calculation of Gubser (1998) to the generalized conifol...

In view of the good properties of nonstationary wavelet frames and the better flexibility of wavelets in Sobolev spaces, the nonstationary dual wavelet frames in a pair of dual Sobolev spaces are studied in this paper. We mainly give the oblique extension principle and the mixed extension principle for nonstationary dual wavelet frames in a pair of dual Sobolev spaces H(R) and H−s(Rd). Keywords...

In the petroleum supply chain, oil refined products are often delivered to distribution centers by pipelines since they provide the most reliable and economical mode of transportation over large distances. This paper addresses the optimal scheduling of a complex pipeline network with multiple branching lines. The main challenge is to find the optimal sequence and time of product injections/deli...

Abstract Mixed finite element methods solve a PDE using two or more variables. The theory of Discrete Exterior Calculus explains why the degrees of freedom associated to the different variables should be stored on both primal and dual domain meshes with a discrete Hodge star used to transfer information between the meshes. We show through analysis and examples that the choice of discrete Hodge ...

While almost all collision detection algorithms have been linked to a particular object representation scheme, few attempts have been made using hybrid methods to exploit the advantages of multiple representations of objects. In this paper we present a collision detection algorithm based on a dual b-rep/CSG representation of concave polyhedra initially represented in b-rep. Our method naturally...
