Resonant Optical Media
ISBN: 9783659329852 / Angielski / Miękka / 112 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Investigating the behavior of an atom in response to the applied electric field when the latter frequency is in resonance with the natural frequency of the atom is an interesting subject. Near resonance, some of the most interesting optical phenomena such as dispersion, and absorption are more pronounced. Moreover, considering resonant and near resonant interaction of light with two-level atoms, uncovers fascinating physical phenomena such as area theorem and self-induced transparency describing stable pulse propagation regimes in which the pulses maintain their identity. Existence of these...

Graphene/ Graphene Oxide Doped Magnesium Diboride Superconductors
ISBN: 9783659332616 / Angielski / Miękka / 156 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Owing to the high critical temperature (Tc) of 40 K, intrinsically "weak-link" free grain boundaries, and low fabrication cost, MgB2 is believed to be promising for replacing conventional low Tc superconductors in many cryogen- free applications. Nevertheless, its rapid drop in critical current under applied magnetic field and low critical field exclude it from many industrial applications where a high critical current density (Jc) under high magnetic field is required. Many studies have shown that carbon containing dopants are effective means to enhance the field dependence of Jc and the...

Modeling and Optimization of High Voltage Power Supply for Magnetron
ISBN: 9783659372094 / Angielski / Miękka / 76 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The high voltage power supply for magnetron, used for the modular microwave generators in industrial applications, is a classical design. This system is composed of a single-phase high voltage transformer with shunts supplying a cell, composed of a capacitor and a diode, which doubles the voltage and stabilizes the current. In this case, the leakage fluxes in the magnetic shunts are of the same order in the primary and the secondary fluxes. In this work, a π quadruple model of this leakage transformer is developed taking account the saturation phenomena and the stabilization of the...

Power System Observability
ISBN: 9783659438462 / Angielski / Miękka / 116 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Phasor measurement units (PMUs) are considered as a promising tool for future monitoring, protection and control of power systems. One of the applications of phasor measurements is state estimation. The first step in state estimation is to gather measured data from different substations in a power network. These measurements must be sufficient to make the system observable. This book adopts three algorithms for minimizing the size of the PMU configuration while allowing full observability of the network; Depth First Search (DFS), Simulated Annealing (SA) and Minimum Spanning Tree (MST)...

Levitating Precision Positioner
ISBN: 9783659460975 / Angielski / Miękka / 204 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Precision positioning is a challenging engineering field. Especially in cryogenic environments, where contact between parts tend to limit the lifetime, accuracy and stroke of positioners. Together with the extremely low temperatures and typically high vacuum levels, power dissipation, wear, cold welding or the lack of options for effective lubrication are some of the main concerns to aerospace engineers. In this thesis, the authors propose an innovative solution based in superconducting magnetic levitation. A long-stroke linear slider composed of a permanent magnet carrying an optic cube is...
