Research ArticleOpen accessIn the abstractSeismic Behavior of Vertical Shear Links made of Easy-Going SteelAmir Saedi Daryan, Hesam Bahrampoor, Masood Ziaei et al.Problem Statement: Since the time that steel was first used as a construction material, engineers have attempted to increase strength, reduce weight and produce more economical structures by using elegant member sections. However, the increase in steel strength and the decrease in cross section area are not always useful and in some cases it is necessary to reduce the strength … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,218 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Applied Research Program on Water Desalination with Renewable EnergiesSergio M. Alcocer, Gerardo HiriartThe use of renewable energy for desalination might be quite different in many places of the world. In Mexico, specifically in Baja California, there is an abundance of "traditional" renewable resources like sun and wind but also some others like hot springs at the coast, tidal currents and tidal amplitudes of over six meters in the upper part of the … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 7,208 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPitch Angle Control of Variable Speed Wind TurbineYousif El-TousThe aim of this study is to design a simple controller to maximize the extracted energy of wind turbines. In this study the pitch angle control of variable speed wind turbine is investigated. In particular, it concentrates on the extraction of maximum available energy, reduction of torque and output power variations, which gives stresses in the gearbox and mechanical structure. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 8,740 accessesView PDF Cite

Research ArticleOpen accessIn the abstractWind Speed Simulation Using WaveletsA. H. Siddiqi, S. Khan, S. RehmanMost of the renewable energy sources have direct or indirect link with the sun. Wind is also a form of solar energy. It is initiated by uneven heating of the atmospheric air by the sun, affected from the topography and surface roughness of the earth's surface and rotation of the earth. The earth's terrain, water surfaces and vegetation cover modifies … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,553 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPresentation of Romanian Engineers who Contributed to the Development of Global Aeronautics – Part IRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.It is said that "the Romanian is born poet". And so it is, but we could say rather that "the Romanian is born and an engineer", having deeply embedded himself, the vocation of the builder, the innovator, the inventor. The great cathedrals, the beautiful monasteries built, or even the churches and churches (built or wooden) clearly show this vocation. After … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 4 · 1 Dec 2017 · 7,285 accessesView PDF Cite

Review ArticleOpen accessAll words, across the recordRomanian Engineering "On the Wings of the Wind"Relly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuThe presented study proposes a commemoration of the main artisans of the Romanian and world aviation, from its beginnings to the day. Very briefly are brought to the forefront, the main inventors of flying machines and equipment that have lived here in the Romanian territory and have contributed substantially to the development of any type of flight. We will talk … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 18 Jan 2018 · 9,414 accessesView PDF Cite
