In this work, an innovative method for controlling the current distribution of radiating patch by adjusting input phase is investigated to achieve both pattern and polarization reconfigurable characteristics multifunction. A compact low-profile antenna with four fed ports designed implement proposed method, which can operate linear, right-hand circular (RHCP) left-hand (LHCP) different beam dir...

Modular approach and microcontroller technology reduce costs and increase reliability in the Electric aesthetic applications

A complete, working document storage and retrieval system is described. Designed to help users solve the problem of lost documents, this system illustrates the concepts of automatic document capture and easy retrieval. Every document a user copies or prints is automatically indexed and saved for later retrieval. A prototype implementation of such a system was constructed and used daily by appro...

Thepaper ismainly devoted to the studyof implicitmultifunction theorems in terms of Fréchet coderivative inAsplund spaces. It sharpens thewell-known implicit multifunction theorem of Ledyaev and Zhu (Set Valued Anal., 7, 209–238, 1999) as well as many recent publications about this significant area.

We prove the existence of viable solutions for an autonomous second-order functional differential inclusions in the case when the multifunction that define the inclusion is upper semicontinuous compact valued and contained in the subdifferential of a proper lower semicontinuous convex function.

The existence of monotone solutions for a second-order functional differential inclusion is obtained in the case when the multifunction that define the inclusion is upper semicontinuous compact valued and contained in the Fréchet subdifferential of a φ-convex function of order two.

In this paper, we further a previous study concerning convergences and pseudo-convergences of sequences of measurable functions on monotone set multifunction spaces. Various considerations concerning operations and the uniqueness of the limit with respect to such convergences are given and several asymptotic structural properties of certain set multifunctions are, in this way, characterized.
