Authors suggest a comparative study, which allows selecting the most innovative clusters in Morocco and Italy, and making comparisons between and within them. The analysis defines the weaknesses and strengths in the both examined clusters and embrace three dimensions of cluster activity, so called, “Humain and Material Resources, Activities, Processes and strategies”. In this paper, we start by giving a global presentation of Moroccan clusters, their history and geolocation. As a first case of study, we focused on the “Maroc Numeric Cluster” (MNC) manely on its limitations and weaknesses. Thus, in the second case study, we present a cluster that is the beating heart of Italian excellence in the energy sector (Lombardy Energy Cleantech Cluster LE2C). The aim of this paper is to present the LE2C strengths and successful strategies in order to adapt them to the MNC cluster so that it can promote and accelerate again with a successfull proccess.

The developed network which contains two subnets, a distribution subnet and a scanning subnet, is considered as a first step to design an adaptive microstrip antenna for UMTS use. The patch distribution structure used in this experiment allowed a great improvement of gain, directivity as well as the adaptation level of the studied array. The following work was realized in the laboratory signals, systems and components of FST-Fes, in colaboration with the Microwave Laboratory of the National Institute of Posts and Telecommunications of Rabat. Keywords—microstrip antenna array; electromagnetic coupling; adaptive microstrip antenna; tree patch distribution structure.

This switch will allow us to deliver RF energy via an output of four and will be integrated into a microstrip adaptive antenna array circuit. The following work is done between the signals, systems and components laboratory of FST-Fez and the microwave laboratory of the National Institute of Posts and Telecommunications of RABAT MOROCCO.

The inflexible nature of these environments must be adapted to learners and their profiles in order to gain suppleness, adaptation and individualization of learning. So they can be an effective tool for representation and consideration of the learner’s knowledge and skills. This new learning technique imposes new requirements and constraints to establish representations through which learner modeling becomes possible. We present our learner modeling approach built
