In this work, we are interested by emulating metamaterial microwave waveguides which behave like conventional metallic ones. We use metamaterial layers based on two types of unit cells. The first one is a connected cross type unit cell which leads to a metamaterial with a near zero refraction index (n1 ≈ 0). The second one is a disconnected cross type unit cell which leads to a metamaterial with a...
In recent years identification and control algorithms applied to heating, ventilation and air conditioning (HVAC) systems have been paid an increasing attention. The main idea of this paper is to exploit the learning capacity of Radial Basic Function Neural Networks (RBFNN) for adaptation and control of multi-zone building heating regulation. Several inputs and disturbances that influence the indoor...
The building sector is considered a major consumer of energy among all economic sectors. It represents approximately 40 percent of energy consumption. An important energy consumer is associated with building heating systems. The main objective of this paper is to use a novel supervisory control strategy based on RBF neural networks architecture to achieve a good temperature regulation in a building...
Cell nucleus characterization is essential for pathological image analysis. In this article, we propose a shape characterization of the cell nucleus based on some selected shape descriptors. In order to separate automatically the different cell nucleus shapes, we focus our effort on the feature extraction and classification processes. The main contribution of our work is the creation of a new shape...
This paper introduces compact music-inspired computing. We propose a music-inspired optimization technique with minimal computational cost. The aim is to reduce the memory storage capacity required by the classical harmony search algorithm (HSA) while improving their performance. Therefore, we propose three compact harmony search algorithms. The main idea is to represent the harmonies stored in the...
The paper addresses the boundary control of a linear parabolic equation. The objective consists in controlling a given punctual output. The formulated control problem is characterized by an infinite characteristic index making the controller design a challenging task. Hence, to overcome this difficultly and design a state feedback, in the framework of geometric control, an equivalent distributed model,...
