Nonlinear Optical Frequency Conversion to and from the Mid-Infrared
ISBN: 9783838129938 / Angielski / Miękka / 132 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Mid-infrared (MIR) sources and detectors are of strong interest. Due to a lack of favorable lasers, frequency conversion using nonlinear optical difference-frequency generation (DFG) has been a popular means to generate MIR radiation using near-IR (NIR) sources. On the detector side, optical frequency conversion can be used to realize a hybrid up-conversion detector (UCD). In this case, radiation is converted from the MIR to the NIR or even visible, where detectors with exceptional properties are available. Such devices, based on Ti-indiffused waveguides in periodically poled Lithium Niobate,...

Improved Space to Height Index Considering Critical Height
ISBN: 9783639663556 / Angielski / Miękka / 56 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Since space to height index is effective on uniform illumination of working plane and it has been improved for two types of light sources, namely, point- and surface-circular-light sources in the literature, this study improves space to height index for line-light sources. Furthermore a comparison between new space to height indices and DIALux4.12 standard space to height indices, i.e. 0.25 and 1, is demonstrated for all of light sources.

ISBN: 9781489921413 / Angielski / Miękka / 902 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The NATO Advanced Study Institute on Quantum Electrodynamics of Strong Fields was held at Lahnstein on the Rhine from 15-26 June, 1981. The school was devoted to the advances, theoretical and exper imental, in the physics of strong fields made during the past decade. The topic of the first week was almost exclusively quantum electrodynamics, with discussions of symmetry breaking in the ground state, of the physics of heavy ion collisions and of precision tests of perturbative quantum electrodynamics. This was followed in the second week by the presentation of a broad range of other areas...

Europium Doped Zinc Oxide Nanorods, Structural and Optical Properties
ISBN: 9783659606731 / Angielski / Miękka / 80 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In this book, we report a successful synthesis of well vertically aligned Eu doped ZnO nanorods prepared by pulsed laser deposition (PLD) without any catalyst. The effect of different PLD growth parameters in forming the nanorods and structure has been studied. Laser energy and frequency have an effect on the size and the height of the nanorods; the oxygen pressure changed the density of the nanorods. The ZnO nanorods were analyzed using X-ray diffraction (XRD). The obtained XRD patterns showed ZnO wurtzite structure nanorods grown along the C-axis. Morphological properties of ZnO nanorods...

Optimal Capacity Planning of Distributed Generators
ISBN: 9783659593734 / Angielski / Miękka / 160 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In this book, a method based on a sensitivity analysis and quadratic curve-fitting technique for power loss reduction in a low-voltage distribution area is proposed. For determining the optimum generation capacity of multiple DG units, a new methodology based on an unbalanced multi-phase optimal power flow (UM-OPF) is also presented. During the formulation of the UM-OPF, an optimisation algorithm is developed in Matlab and the unbalanced multi-phase power flow is solved using the Electric Power Research Institute's (EPRI) software OpenDSS. To ensure a global minimum loss profile, adaptive...

This long awaited second edition traces the original developments from the 1970s and brings them up to date with new and previously unpublished material to give this work a new lease of life for the early twenty-first century and readers new to the topic. In the winter of 1970-71, Colman Altman had been finding almost exact symmetries in the computed reflection and transmission matrices for plane-stratified magnetoplasmas when symmetrically related directions of incidence were compared. At the suggestion of Kurt Suchy the complex conjugate wave fields, used to construct the eigenmode...

Polarización y celdas con cristales líquidos nemáticos
ISBN: 9783659035203 / Angielski / Miękka / 120 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. La propagacion de la luz en los cristales liquidos puede describirse con el formalismo clasico para cristales solidos uniaxiales. En dicho formalismo, los efectos inducidos por campos electricos externos al material se reducen a cambios en la inclinacion del eje optico del elipsoide de indices, dando como resultado los estados de polarizacion propios del sistema, representados apropiadamente con la formulacion de Jones. Esta descripcion es el fundamento de los experimentos para caracterizar celdas con cristales liquidos nematicos entre polarizadores lineales. La determinacion de sus...
