In this paper we deal with the control of chaotic systems. Knowing that a chaotic attractor contains a myriad of unstable periodic orbits (UPO’s), the aim of our work is to stabilize some of the UPO’s embedded in the chaotic attractor and which have interesting characteristics. First, using the input-tostate linearization method in conjunction with a timedelayed state feedback, we design a cont...

BACKGROUND This epidemiological study was carried out in Sfax (south of Tunisia) and focused on genital Chlamydia trachomatis (C. trachomatis) genovar distribution. METHODS One hundred and thirty seven genital samples from 4067 patients (4.2%) attending the Habib Bourguiba University hospital of Sfax over 12 years (from 2000 to 2011) were found to be C. trachomatis PCR positive by the Cobas A...

A breeding program has been developed since 1994 (done by Dr A. Trigui), by controlled pollinations of the Tunisian olive oil variety Chemlali Sfax in order to improve the qualities of this variety (higher oil percentage and a better chemical composition). These controlled pollinations have produced a population of new genotypes presented a wide genetic diversity which was very interesting for ...

†University of Sfax, National Engineering School of Sfax, Control and Energy Management Laboratory, Sfax, BPW 30308, Tunisia Summary The human iris is attracting a lot of attention leading to an increased demand for a robust and reliable iris-based recognition system. However, typical systems have random performances which can be efficient for some contexts and not for others. Generally, in rea...

Abstract Monthly Air Surface Temperature (AST) data for Tunis were acquired by the Atmospheric InfraRed Sounder (AIRS) dataset (2003–2021), enrolments of 77 grids, each located in Spatial resolution 1°x1°, converted into monthly and annual analysed. The time series AST investigated temporal spatial trends during study period over six climate stations having sufficient available utilized this pu...
