This paper deals with the development of acoustic source localization algorithms for service robots working in real conditions. One of the main utilizations of these algorithms in a mobile robot is that the robot can localize a human operator and eventually interact with him/herself by means of verbal commands. The location of a speaking operator is detected with a microphone array based algori...

‎In this short note‎, ‎we present some inequalities for relative operator entropy which are generalizations of some results obtained by Zou [Operator inequalities associated with Tsallis relative operator entropy‎, ‎{em Math‎. ‎Inequal‎. ‎Appl.}‎ ‎{18} (2015)‎, ‎no‎. ‎2‎, ‎401--406]‎. ‎Meanwhile‎, ‎we also show some new lower and upper bounds for relative operator entropy and Tsallis relative o...

We prove spectral and dynamical localization for a one-dimensional Dirac operator to which is added an ergodic random potential, with discussion on the different types of potential. use scattering properties positivity Lyapunov exponent through Fürstenberg theorem. get then Hölder regularity integrated density states new version Thouless formula, thus Wegner estimate necessary multiscale analys...

objectives: the aim of the present study was to assess the auditory lateralization ability in children with (central) auditory processing disorder. methods: participants were divided in two groups: 15 children with central auditory processing disorder (8-10 years) and 80 normal children (8-11 years) from both genders with pure-tone air-conduction thresholds better than 20 db hl bilaterally and ...

a wireless sensor network (wsn) is a wireless decentralized structure network consists of many nodes. nodes can be fixed or mobile. wsn applications typically observe some physical phenomenon through sampling of the environment so determine the location of events is an important issue in wsn. wireless localization used to determine the position of nodes. the precise localization in wsns is a co...

We develop a quantum harmonic analysis framework for the affine group. This encapsulates several examples in literature such as localization operators, covariant integral quantizations, and quadratic time-frequency representations. In process, we notion of admissibility operators extend well known results to operator setting. A major theme paper is interaction between convolutions, Weyl quantiz...

The subleading eigenvalues and associated eigenfunctions of the Perron-Frobenius operator for 2-dimensional area-preserving maps are numerically investigated. We closely examine validity so-called Ulam method, a numerical scheme believed to provide operator, both linear nonlinear on torus. For case, second-largest investigated by calculating Fokker-Planck with sufficiently small diffusivity. On...
