<p>Semiconductor lasers are an integral part of high-speed telecommunications. The push for higher modulation frequencies, thereby allowing greater data rates, has motivated the scientific community for several decades. However, as the field matured, the maximum speed of traditional directly-modulated lasers has reached a fundamental limit. Recently, optical injection locking has been proven to enhance the bandwidth and resonance frequency of directly-modulated semiconductor lasers. The injection locking technique allows the lasers to exceed their fundamental modulation speed limit, allowing for greater communication speeds. This book first develops theoretical insight into the nature of resonance frequency and bandwidth enhancement by optical injection locking. The design parameters of resonance frequency enhancement are described and these results are generalized to oscillators of all kinds. High-speed resonance frequencies well over 100 GHz and 3-dB modulation bandwidths in excess of 50 GHz are fundamentally possible. Various types of modulation formats are implemented as well. This book will be useful to anyone interested in the forefront of high-speed optical communications."</p>

This book informs the reader of a study that explores  the music development, achievement and aspirations of  adolescent students participating in pre-tertiary  specialised music programs. A theoretical model is  developed for the study to investigate the role and  influence of such training in the development of  music skills, and explores relationships amongst  music experience, music engagement, interpersonal and  intrapersonal relationships, personal learning  styles, and affective response to music.    The data source for the study is a pre-tertiary  Australian music program. The study was conducted  over two years, used a large student population, a  small group of case studies, and combined  contemporaneous and retrospective approaches.      This study enhances understanding of the conditions  through which music development is nurtured; it  confirms the importance of exposure and opportunity,  the collective efforts of the family and community,  and the need for hard work and perseverance to  usually be exercised by young musicians themselves.    Extensive appendices contain case-study reports,  reflective journals, interviews, surveys, tasks and  tests.

Momentum investment strategy which buys past intermediate-term winner stocks and sells past intermediate-term loser stocks generates positive profits over three-month to one-year holding periods. This price anomaly has attracted a lot of attention since it is inconsistent with the traditional Market-Efficiency Hypothesis. This book uses an extensive international data set first to detect the existence of international momentum effect, then to investigate the sources of momentum profits. With a sample of about 20,000 stocks from 18 developed countries during 1973-2001, we find that an internationally diversified momentum strategy earns significant positive profits over intermediate horizons. On the sources of momentum profits, our findings suggest that momentum phenomenon is linked to information dissemination mechanism among investors, which is consistent with the prediction of existing behavioral theories. Our results also indicate that investing style is not an independent source of momentum. The analysis should be useful for academicians who are interested in testing market efficiency hypothesis, and may also serve as a reference for investment professionals.

This book describes an information architecture designed to achieve intellectual control over large-scale, modular, integrated, fault-tolerant systems that leverage Semantic Web Services for automated analysis and design support during the engineering process. The technology independence of the information architecture reduces risk and saves money by preventing unknown project derailments.The Artificial Intelligence Design Framework (AIDF) developed for NASA provides facilities for 20 modules in the engine block with emphasis on modularity, scalability, reconfigurability, and service integration capability. Risk mitigation is achieved by a comprehensive synergistic validation and verification methodology for each major division of the integrated systems. The AIDF has broad impact and can be applied to any field that may benefit from an automated design/analysis process for improved decision-making. The architecture framework uses validated engine block modules for knowledge engineering and algorithm management, intelligent agents for logic control, and the Internet for invoking Semantic Web Services.

This book introduces an analytic procedure that estimates the amount of traffic congestion (vehicle hours of delay) that is caused by different types of accidents that occur on urban freeways, as well as a model for prediction of real-time accident information such as how long an accident will affect traffic congestion and to the extent of the traffic congestion. The first part describes a method to separate the non-recurrent delay from any recurrent delay that is present on the road at the time and place of a reported accident, in order to estimate the contribution of non-recurrent delay caused by the specific accident. Since a number of estimated delay results were censored by time and/or space boundary conditions, an approach based on survival analysis was applied to analyze estimated delay and to predict traffic congestion impact in terms of time and space. Additionally, this book presents three prediction models regarding the spatio-temporal impact caused by a traffic accident as well as an accident duration model based on AFT metric model.

Of the children who survive a disaster, only a small amount will come through the experience entirely unscathed. The majority of the children will show negative consequences, if only for a short amount of time. But for some, the effects of the disaster will continue to adversely impact their daily functioning for an extended period of time. This impact can be seen in symptoms such as increased worry or anxiety, social withdrawal, and difficulties in concentration. This book details two research studies designed to add to the literature concerning the effects of disasters on children. Both studies examined the roles that re-exposure to environmental cues, exposure to disaster-related media, attributions and coping style, and other factors, such as demographic variables, play in maintaining level of distress. The first study examined these factors in children one year to 18 months after a tornado, while the second compared disaster exposed and non-exposed children at six months and one year after the trauma. Primary findings include the role that attributions play in long-term distress and the high level of reported distress across the samples.
