Multidimensional cosmological, static spherically symmetric and Euclidean configurations are described in a unified way for gravity interacting with several dilatonic fields and antisymmetric forms, associated with electric and magnetic p -branes. Exact solutions are obtained when certain vectors, built from the input parameters of the model, are either orthogonal in minisuperspace, or form mut...

We discuss the universality of the l1 recovery threshold in compressed sensing. Previous studies in the fields of statistical mechanics and random matrix integration have shown that l1 recovery under a random matrix with orthogonal symmetry has a universal threshold. This indicates that the threshold of l1 recovery under a non-orthogonal random matrix differs from the universal one. Taking this...

In this paper we list some new orthogonal main e ects plans for three level designs for and factors in runs and compare them with designs obtained from the existing L orthogonal array We show that these new designs have better projection properties and can provide better parameter estimates for a range of possible models Additionally we study designs in other smaller run sizes when there are in...

An orthogonal double cover (ODC) of a complete graph is a collection of graphs such that every two of them share exactly one edge and every edge of the complete graph belongs to exactly two of the graphs. In this paper, we construct ODCs of Kn where all graphs are isomorphic to certain spanning subgraphs G (such as co-triangles, a star with cotriangles, and two other graph classes).

In order to produce any product with desired quality by machining, proper selection of process parameters is essential. This can be accomplished by Full Factorial method. The aim of the present work is to investigate the effect of process parameter on surface finish and material removal rate (MRR) to obtain the optimal setting of these process parameters and the analysis of variance is also use...

We have performed a shape optimization of the disc in an industrial double-eccentric butterfly valve using the effect analysis of design variables to enhance the valve performance. For the optimization, we select three performance quantities such as pressure drop, maximum stress, and mass (weight) as the responses and three dimensions regarding the disc shape as the design variables. Subsequent...

Multiresolution is investigated on the basis of shift-invariant spaces. Given a finitely generated shift-invariant subspace S of L2(IR), let Sk be the 2-dilate of S (k ∈ ZZ). A necessary and sufficient condition is given for the sequence {Sk}k∈Z to form a multiresolution of L2(IR). A general construction of orthogonal wavelets is given, but such wavelets might not have certain desirable propert...
