Remote Sensing for Conservation of Acacia Trees in Arid Environment
ISBN: 9783659494147 / Angielski / Miękka / 2014 / 208 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Acacia tortilis is the most widespread, drought-resistant and heat tolerant species, it grows in desert wadis and sandy plains usually in water catchments' areas. It is a multipurpose tree provides several products such as timber, Gums, tannins, firewood, charcoal, and fodder for livestock, in addition to environmental protection, and soil fertility. Despite its recognized importance to human welfare and economy, it became threatened due to aridity and unmanaged human activities; including over-grazing, over-cutting, and habitat destruction. This book is about the integration of remote...

Mixed Pole Machines
ISBN: 9783659181870 / Angielski / Miękka / 2012 / 312 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The idea of the mixed-pole machine is to have two electrically connected and mechanically coupled machines in one frame. The stator of this machine comprises two windings each with a different number of pole pairs, p1 and p2. Machine operation relies on the interaction between the two stator fields due to the especially designed rotor. The mixed pole machine has many applications in low cost adjustable speed drives and variable speed generators. It has also shown promise in the generating mode of operation, especially in the field of electrical generation from wind energy. This work presents...

New Urban Development and the Historic Environment
ISBN: 9783659643149 / Angielski / Miękka / 2014 / 216 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Controlling the quality of new development introduced inside the historic environment represents one of the crucial tools that can help in confronting the challenges facing our cities. Present-day challenges facing the historic environment inside the Egyptian cities involve, among other things, the prevalence of run-down urban areas and the dominance of visual clutter. The enactment of the Act No. 119 and the introduction of the idea to designate areas that enjoy a distinctive value represent the first steps on the right track to develop the Egyptian experience in the management of the...

Fault-Tolerant Control of Multiphase Induction Motor Drives
ISBN: 9783659409745 / Angielski / Miękka / 2013 / 140 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Although three-phase electric machines play a great role in almost all industrial applications, they still have limitations to cover high power requirements needed for traction, propulsion and other high power applications. Nowadays, multiphase electric machines with high output power can solve this problem. A multiphase machine does not only provide higher torque per unit volume, but it also provides higher degrees of reliability due to fault-tolerant capability provided by the additional degrees of freedom. This is a crucial issue for safety-critical applications, e.g., electric ship...
