Item Algerian energy policy and potential to reducing greenhouse gas emissions(Taylor & Francis, 2016) Sahnoune, Fatiha; Belhamel, M.; Zelmat, M.In Algeria, energy consumption is growing rapidly. Due to the high demand and declining conventional energy resources, the country developed a new energy policy based on the promotion of renewable energies and CO2 mitigation. For this purpose, the authorities have taken new steps to reinforce the legislative and institutional framework and put in place a favorable financial support. In addition, an ambitious program to develop solar energy and energy efficiency was adopted recently. The objective of this strategy is to achieve by 2030 a 40% share of solar electricity and to contribute, voluntarily, to reducing greenhouse gas (GHG) emissions. In this work, we present an analysis of the current situation and its projection to 2030 and we examine the available opportunities to reduce significantly GHG emissions. The study presents the magnitude of emissions in 2008 and 2012, the temporal evolution of CO2 and particularly what will be the impact on GHG emissions of the new strategy. The results show that, in 2012, GHG emissions totaled 153 MT CO2 eq. and growing at a rate of over 3%. However, there is a high potential for mitigation, especially in energy sectors, in building, transportation, as well as waste management and gas flaring. Two scenarios are developed: with implementation of solar energy and without. This analysis shows that the overall potential of CO2 mitigation will rise in 2030 to about 300 MT CO2 eqItem Fuzzy logic based gradient descent method with application to a PI-type fuzzy controller tuning : new results(IEEE, 2007) Habbi, A.; Zelmat, M.Item Unknown input proportional integral observer design for chaotic TS fuzzy models(Springer, 2013) Youssef, T.; Chadli, Mohammed; Zelinka, Ivan; Zelmat, M.Item Design of unknown inputs proportional integral observers for TS fuzzy models(Elsevier, 2014) Youssef, T.; Chadli, M.; Karimi, H.R.; Zelmat, M.Item Performance improvement of large-scale solar water heating systems by using remote monitoring(Revista Tecnica de la Facultad de Ingeniera, 2015) Sahnoune, F.S.; Belhamel, M.; Zelmat, M.Item Une approche améliorée pour l'optimisation des contrôleurs flous(Journal Europeen des Systemes Automatises, 2002) Habbi, H.; Zelmat, M.In this paper, an improved adaptation mechanism for tuning of fuzzy logic controllers using gradient descent method is proposed. The proposed algorithm is used for input/output membership functions tuning of a fuzzy controller by minimising some criterion on the control output. The optimisation problem is solved using gradient descent technique. In this tuning procedure, the constant which controls how much the fuzzy controller parameters are altered at each iteration is updated using a fuzzy logic approximate reasoning modelled as a set of IF-THEN rules. To illustrate the usefulness and the effectiveness of the improved algorithm, we consider the problem of minimising the matching error induced by an additive noise affecting the input information of a Pi-like fuzzy controllerItem Prediction of boiler output variables through the PLS linear regression technique(2011) Kouadri, A.; Zelmat, M.; Albarbar, A.Item Bearing damage detection and diagnosis by multi-scale PCA and Power quality distribution of rotating machinery(2011) Baiche, Karim; Zelmat, M.; Lachouri, A.Item Pedestrian tracking using color, thermal and location cue measurements : a DSmT-based framework(Springer, 2012) Airouche, Mohamed; Bentabet, L.; Zelmat, M.; Gao, G.Item Comparative study between solar and conventional heating-economic study and environmental impact(Elsevier, 2014) Sahnoune, Fatiha; Madani, M.; Zelmat, M.; Belhamel, M.
