Modern Electrical Insulation
ISBN: 9783659372568 / Angielski / Miękka / 144 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book is on modern electrical insulation. The insulator is backbone of any transmission/ distribution system. In the past, ceramic insulator have been used since 1880. But sine last three decades people are now using polymeric insulators which are better than ceramics in many respects like, light weight, easy to install, better pollution performance and more aesthetic. These insulators are made of silicon insulator rubber and thermoplastic elastomers. These materials are partially organic and partially inorganic. Due to organic nature, these degrade with the time due to environmental...

Quantum Optical Analogies in Waveguide Based Optical Structures
ISBN: 9783659377242 / Angielski / Miękka / 108 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Analogy is a basic concept for understanding nature, since it analyses and connects different phenomena linked by common properties or similar behavior. In particular, analogy can to some extent apply to specific quantum phenomena and their corresponding classical effects, although quantum physics differs from classical physics in both formalism and fundamental concepts. The main motivation on studying quantum optical analogies rely on the fact that analogies between different fields of physics have proven themselves extremely fruitful in understanding the basic physical concepts and the...

ISBN: 9783319007823 / Angielski / Twarda / 137 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This thesis explores a route to induce and control the structure formation process in thin films by the use of strong electric fields. We investigate, establish and apply the use of the electrohydrodynamic (EHD) lithography as a versatile patterning tool on the sub-micrometre and nanometre length scales for functional materials. Thin films are ubiquitous, they are found in nature and used in almost every aspect of daily life. While film instabilities are often undesirable in nature and technology, they can be utilized to produce structures by precisely controlling the destabilization of the...

Simulation of Back-Flashover Caused by Lightning
ISBN: 9783659360848 / Angielski / Miękka / 168 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Lightning strokes represent a considerable cause of short interruptions in overhead line transmission line networks. The over voltages caused by lightning cannot be avoided but their influence can be limited by appropriate overvoltage protection. Lightning is one of the main causes of problems on transmission lines; this is usually happening when a stroke hits: the phase conductor, the ground wire or directly the structure. If the first case occurs, the line may have a shielding failure. Meanwhile in the second or third cases, there may be a back flashover, which generally depends on a high...

New Computation Methods for Geometrical Optics
ISBN: 9789814451789 / Angielski / Twarda / 239 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book employs homogeneous coordinate notation to compute the first- and second-order derivative matrices of various optical quantities. It will be one of the important mathematical tools for automatic optical design. The traditional geometrical optics is based on raytracing only. It is very difficult, if possible, to compute the first- and second-order derivatives of a ray and optical path length with respect to system variables, since they are recursive functions. Consequently, current commercial software packages use a finite difference approximation methodology to estimate these...
