A class of associative algebras called cyclotomic Temperley-Lieb algebras is introduced in terms of generators and relations. They are closely related to the group algebras of complex reflection groups on one hand and generalizations of the usual Temperley-Lieb algebras on the other hand. It is shown that the cyclotomic Temperley-Lieb algebras can be defined by means of labelled Temperley-Lieb ...

This study proposes a method for the acceleration of the projection method to compute a few eigenvalues with the largest real parts of a large nonsymmetric matrix. In the eld of the solution of the linear system, an acceleration using the least squares polynomial which minimizes its norm on the boundary of the convex hull formed with the unwanted eigenvalues are proposed. We simplify this metho...

Circularly polarized millimeter-wave travelling-wave antennas, using substrate integrated circuits (SICs) technology, are designed, fabricated and tested. By using the SICs technology, compact antennas with low losses in the feeding structure and with good design accuracy are obtained. The elementary antenna which is composed of two inclined slots is characterized by full-wave simulations. This...

This study proposes a new method for the acceleration of the projection method to compute a few eigenvalues with the largest real parts of a large nonsymmetric matrix. In the eld of the solution of the linear system, an acceleration using the least squares polynomial which minimizes its norm on the boundary of the convex hull formed with the unwanted eigenvalues are proposed. We simplify this m...

The problem of inverse design is rooted to the classical scattering. In general, these highly nonlinear and often ill-posed problems are solved via extensive optimization techniques. this paper, we suggest an optimization-free method for a one-dimensional medium with spatially inhomogeneous dielectric constant $?(z)$. addition, derive governing equation analog problem---a time-dependent homogen...

With the advent of lighter and stronger composite materials over the last two decades, more and more metals have been replaced by composite materials in aircraft and other vehicles. It is not suprising that the airframes of certain aircraft (e.g. Lear Fan 2100) are totally fabricated from composite materials. Composites consist of a reinforcing material suspended in a “matrix” material (e.g. ep...

A procedure for detecting outliers in regression problems is proposed. It is based on information provided by boosting regression trees. The key idea is to select the most frequently resampled observation along the boosting iterations and reiterate after removing it. The selection criterion is based on Tchebychev’s inequality applied to the maximum over the boosting iterations of ...
