Algeria plays a very important role in world energy markets, both as a significant hydrocarbon producer and as an exporter, as well as a key participant in the renewable energy market. Due to its geographical location, Algeria holds one of the highest solar potentials in the world. This paper presents a review of the present renewable energy situation and assesses present and future potential of renewable energy sources (RESs) in Algeria. This paper also discusses the trends and expectation in solar systems applications and the aspects of future implementation of renewable energies in the Middle East and North Africa (MENA) region status. The problem related to the use of RES and polices to enhance the use of these sources are also analysed in this paper. In addition the available capacity building, the technical know-how for each RES technology and localizing manufacturing of renewable energy equipments are defined. The co-importance of both policy and technology investments for the future Algerian markets of RES and competitiveness of the solar/wind approach is emphasized. Some examples of policy significantly impacting Algerian markets are reviewed, and the intention of the new Algerian RES initiative is discussed. © 2010 Elsevier Ltd.

We present the results of a multicanonical Monte Carlo study of flexible and wormlike polymer chains, where we investigate how the polymer structures observed during the simulations, mainly coil, liquid, and crystalline structures, can help to construct a hyperphase diagram that covers different polymer classes according to their thermodynamic behavior. © 2014 Versita Warsaw and Springer-Verlag Wien.

Energy security, economic growth and environmental protection are the national energy policy drivers of any country of the world. Scientists, governments, and industries are witnessing the long-term consequences of energy consumption and foresee catastrophic outcomes if alternative methods of energy production are not developed and utilised to meet the needs of our global economy. In recent years, PV is proposed as a competitive energy policy and a step forward to the target of sustainable development and environmental friendly energy source. In this contribution a particular attention is being given to the joint event that bring together the relevant parties, the University of Sciences and Technology of Oran (USTO), Japan International Corporation and Japan Science and Technology Agencies (JICA, JST) to develop a long-term vision and strategy to boost the ideas for the realization and the development of the Sahara Solar Breeder (SSB) project. SSB advocates the view of undertaking collaborative basic, applied and development research, as well as industrial production and technical, commercial and financial support services to implement photovoltaic solar energy systems. The strategic objective is the establishment of a Global Clean Energy Superhighway as the solution to global energy challenges, water shortages, levelling of electric power supply in the world, climate change and other environmental problems arising from the current fossil-fuel heavy global energy paradigm . This project will tackle the key challenges and issues related to the field of PV putting forward the USTO perspective and promoting its R/D activities by a collaborative research plan between Japan and Algeria. This event also seeks to identify the most important challenges facing both the research and economic sectors and put forward new strategies that will identify the required skills to transform the research prospects of USTO based on the analysis and prospect of elementary processes and system design. © 2011 Elsevier Ltd.

It is a well known fact that eight countries have 81% of all world crude oil reserves, six countries have 70% of all natural gas reserves and eight countries have 89% of all coal reserves. Energy is central to achieving the interrelated economic, social, and environmental aims of sustainable human development. But if we are to realise this important goal, the kinds of energy we produce and the ways we use them will have to change. Otherwise, environmental damage will accelerate, inequity will increase, and global economic growth will be jeopardised. Energy produced and used in ways that support human development in all its social, economic and environmental dimensions is what is meant by sustainable energy. The generation of energy by clean, efficient and environmental-friendly means is now one of the major challenges for engineers and scientists. This paper reviews a proposed energy-related solution to global warming, air pollution mortality, and energy security. It discusses recent topics related directly to energy production such as fuel cells (FCs) which represent a promising clean and efficient energy conversion technology. The paper also focuses on those technologies which, in terms of cost, cleanliness, reliability and availability, have the potential to compete with conventional energy conversion systems and to reach commercialisation phase before 2015. © 2011 Elsevier Ltd.

This paper deals with the use of the instantaneous active and reactive power signature analyses and their derived signalsthe instantaneous power factor and phase anglefor discriminating broken rotor bars and airgap eccentricity conditions (rotor faults) from mechanical load oscillation effects in operating three-phase squirrel cage induction motors. Both simulation and experimental results are presented to show the effectiveness and the merits of the proposed approach that offers the possibility to distinguish between the three conditions by comparing the signature analyses of two different quantities for each abnormality condition. © 2011 IEEE.
