In this paper we present a solution for the routing problem related to university course timetabling. We propose a heuristic algorithm that reduces the total distance travelled by each group of student between the different buildings occupying classrooms. This heuristic was tested using real data from the faculty of economic and management sciences of Sfax in Tunisia. The obtained results have ...

An epidemiological study of canine leishmaniasis (CanL) was carried out in nine districts of Sfax, in the southern central part of Tunisia. Sera from 250 dogs were tested by two serological methods: the indirect immunofluorescence antibody test and the counter-immunoelectrophoresis. Seven to eight months later, before the next season of transmission, seropositive dogs from the first test were r...

-The selection of third party logistics (TPL) providers is an important issue for enterprises to outsource their logistics business. In this paper we propose a comprehensive evaluation model for TPL suppliers based on AHP method. Furthermore, we Base on the evaluation index system including logistics cost, the logistics operation efficiency and the basic qualities of service. The efficiency and...

BACKGROUND The genetic diversity of M. bovis in Tunisia is still underestimated despite the implementation of an eradication program. The lack of data about spatial distribution of the M. bovis population hinders the control of bovine tuberculosis (bTB) progress. This study represents the largest molecular analysis of M. bovis isolates in Tunisia. It is aimed to upgrade the understanding of bTB...

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...
