We propose a new non-parametric adaptive detector for detecting an unknown broadband signal in interference consisting of non-stationary narrowband components and a locally stationary broadband component. An important feature of this detector is that it needs no prior information about the signal or interference. The proposed detector is based on the integration of the non-parametric power law ...

In this paper, we present some fixed point theorems for single valued mappings on $K$-complete, $M$-complete and Symth complete quasi metric spaces. Here, for contractive condition, we consider some altering distance functions together with functions belonging to $C$-class and $A$-class. At the same time, we will consider two different type $M$ functions in contractive conditions because the qu...

This paper discusses some mat hematical issues related to empirical mode decomposition (EMD). A B-spline EMD algorithm is introduced and developed for the convenience of mathematical studies. The numerical analysis using both simulated and practical signals and application examples from vibration analysis indicate that the B-spline algorithm has a comparable performance to that of the original ...

In this talk we discuss the possible closures of geodesic planes in a hyperbolic 3-manifold M. When M has finite volume Shah and Ratner (independently) showed that a very strong rigidity phenomenon holds, and in particular such closures are always properly immersed submanifolds of M with finite area. Manifolds with infinite volume, however, are far less understood and are the main subject of th...

levels of representational redescription (Karmiloff-Smith, 1992). But then what causal role is left for second-order intentional states? In our view, the highest level psychological descriptions of behaviors do not necessarily directly prompt the behavior they attend. To be sure, in some cases they may do so, but in many other cases they may serve to regulate behavior at a higher level of hiera...

For an inclusion F < G < L of connected real algebraic groups such that F is epimorphic in G, we show that any closed F -invariant subset of L/3 is G-invariant, where 3 is a lattice in L. This is a topological analogue of a result due to S. Mozes, that any finite F -invariant measure on L/3 is G-invariant. This result is established by proving the following result. If in addition G is generated...

The aim of this paper is to  establish some fixed point theorems for $alpha$-admissible Mizoguchi-Takahashi contractive mappings defined on a ${b}$-metric space which generalize the results of Gordji and Ramezani cite{Roshan6}. As a result, we obtain some coupled fixed point theorems which generalize the results of '{C}iri'{c} {et al.} cite{Ciric3}. We also present  an application in order to i...
