Indium Nitride and Related Alloys

Indium Nitride and Related Alloys

Written by recognized leaders in this dynamic and rapidly expanding field Indium Nitride and Related Alloys provides a clear and comprehensive summary of the present state of knowledge in indium nitride (InN) research. It elucidates and clarifies the often confusing and contradictory scientific literature to provide valuable and rigorous insight into the structural optical and electronic properties of this quickly emerging semiconductor material and its related alloys. Drawing from both theoretical and experimental perspectives it provides a thorough review of all data since 2001 when the band gap of InN was identified as 0. 7 eV. The superior transport and optical properties of InN and its alloys offer tremendous potential for a wide range of device applications including high-efficiency solar cells and chemical sensors. Indeed the now established narrow band gap nature of InN means that the InGaN alloys cover the entire solar spectrum and InAlN alloys span from the infrared to the ultraviolet. However with unsolved problems including high free electron density difficulty in characterizing p-type doping and the lack of a lattice-matched substrate indium nitride remains perhaps the least understood III-V semiconductor. Covering the epitaxial growth experimental characterization theoretical understanding and device potential of this semiconductor and its alloys this book is essential reading for both established researchers and those new to the field.

Integrated Micro-Ring Photonics Principles and Applications as Slow Light Devices Soliton Generation and Optical Transmission

Micro-ring resonators (MRRs) are employed to generate signals used for optical communication applications where they can be integrated in a single system. These structures are ideal candidates for very large-scale integrated (VLSI) photonic circuits since they provide a wide range of optical signal processing functions while being ultra-compact. Soliton pulses have sufficient stability for preservation of their shape and velocity. Technological progress in fields such as tunable narrow band laser systems multiple transmission and MRR systems constitute a base for the development of new transmission techniques. Controlling the speed of a light signal has many potential applications in fiber optic communication and quantum computing. The slow light effect has many important applications and is a key technology for all optical networks such as optical signal processing. Generation of slow light in MRRs is based on the nonlinear optical fibers. Slow light can be generated within the micro-ring devices which will be able to be used with the mobile telephone. Therefore the message can be kept encrypted via quantum cryptography. Thus perfect security in a mobile telephone network is plausible. This research study involves both numerical experiments and theoretical work based on MRRs for secured communication. | Integrated Micro-Ring Photonics Principles and Applications as Slow Light Devices Soliton Generation and Optical Transmission

Time Series Modelling with Unobserved Components

Time Series Modelling with Unobserved Components

Despite the unobserved components model (UCM) having many advantages over more popular forecasting techniques based on regression analysis exponential smoothing and ARIMA the UCM is not well known among practitioners outside the academic community. Time Series Modelling with Unobserved Components rectifies this deficiency by giving a practical overview of the UCM approach covering some theoretical details several applications and the software for implementing UCMs. The book’s first part discusses introductory time series and prediction theory. Unlike most other books on time series this text includes a chapter on prediction at the beginning because the problem of predicting is not limited to the field of time series analysis. The second part introduces the UCM the state space form and related algorithms. It also provides practical modeling strategies to build and select the UCM that best fits the needs of time series analysts. The third part presents real-world applications with a chapter focusing on business cycle analysis and the construction of band-pass filters using UCMs. The book also reviews software packages that offer ready-to-use procedures for UCMs as well as systems popular among statisticians and econometricians that allow general estimation of models in state space form. This book demonstrates the numerous benefits of using UCMs to model time series data. UCMs are simple to specify their results are easy to visualize and communicate to non-specialists and their forecasting performance is competitive. Moreover various types of outliers can easily be identified missing values are effortlessly managed and working contemporaneously with time series observed at different frequencies poses no problem.

British Rock Modernism 1967-1977 The Story of Music Hall in Rock

British Rock Modernism 1967-1977 The Story of Music Hall in Rock

British Rock Modernism 1967-1977 explains how the definitive British rock performers of this epoch aimed not at the youthful rebellion for which they are legendary but at a highly self-conscious project of commenting on the business in which they were engaged. They did so by ironically appropriating the traditional forms of Victorian music hall. Faulk focuses on the mid to late 1960s when British rock bands who had already achieved commercial prominence began to aspire to aesthetic distinction. The book discusses recordings such as the Beatles' Magical Mystery Tour album the Kinks' The Village Green Preservation Society and the Sex Pistols' Never Mind the Bollocks Here's the Sex Pistols and television films such as the Beatles' Magical Mystery Tour and the Rolling Stones' Rock and Roll Circus that defined rock's early high art moment. Faulk argues that these 'texts' disclose the primary strategies by which British rock groups mostly comprised of young working and lower middle-class men made their bid for aesthetic merit by sampling music hall sounds. The result was a symbolically charged form whose main purpose was to unsettle the hierarchy that set traditional popular culture above the new medium. Rock groups engaged with the music of the past in order both to demonstrate the comparative vitality of the new form and signify rock's new art status compared to earlier British pop music. The book historicizes punk rock as a later development of earlier British rock rather than a rupture. Unlike earlier groups the Sex Pistols did not appropriate music hall form in an ironic way but the band and their manager Malcolm McLaren were obsessed with the meaning of the past for the present in a distinctly modernist fashion. | British Rock Modernism 1967-1977 The Story of Music Hall in Rock

Ritual and Music of North China Volume 2: Shaanbei

Ritual and Music of North China Volume 2: Shaanbei

This second volume of Stephen Jones' work on ritual and musical life in north China again with accompanying downloadable resources gives an impression of music-making in daily life in the poor mountainous region of Shaanbei northwest China. It conveys some of the diverse musical activities there around 2000 from the barrage of pop music blaring from speakers in the bustling county-towns to the life-cycle and calendrical ceremonies of poor mountain villages. Based on the practice of grass-roots music-making in daily life not merely on official images the main theme is the painful maintenance of ritual and its music under Maoism its revival with the market reforms of the 1980s and its modification under the assaults of TV pop music and migration since the 1990s. The text is in four parts. Part One gives background to the area and music-making in society. Parts Two and Three discuss the lives of bards and shawm bands respectively describing modifications in their ceremonial activities through the twentieth century. Part Four acclimatizes us to the modern world with glimpses of various types of musical life in Yulin city the regional capital illustrating the contrast with the surrounding countryside. The 44-minute downloadable resources with its informative commentary is intended both to illuminate the text and to stand on its own. It shows bards performing at a temple fair and to bless a family in distress and shawm bands performing at a wedding at funerals and a shop opening - including their pop repertory with the 'big band'. Also featuring as part of these events are opera troupes geomancers and performing beggars; by contrast the film shows a glimpse of the official image of Shaanbei culture as presented by a state ensemble in the regional capital. The publication will appeal to ethnomusicologists anthropologists and all those interested in modern Chinese history and society. | Ritual and Music of North China Volume 2: Shaanbei
