André Röhm investigates the dynamic properties of two-state lasing quantum dot lasers, with a focus on ground state quenching. With a novel semi-analytical approach, different quenching mechanisms are discussed in an unified framework and verified with numerical simulations. The known results and experimental findings are reproduced and parameter dependencies are systematically studied. Add…
This SpringerBrief presents adaptive resource allocation schemes for secondary users for dynamic spectrum access (DSA) in cognitive radio networks (CRNs) by considering Quality-of-Service requirements, admission control, power/rate control, interference constraints, and the impact of spectrum sensing or primary user interruptions. It presents the challenges, motivations, and applications of the…
The two-volume set LNCS 9172 and 9173 constitutes the refereed proceedings of the Human Interface and the Management of Information thematic track, held as part of the 17th International Conference on Human-Computer Interaction, HCII 2015, held in Los Angeles, CA, USA, in August 2015, jointly with 15 other thematically similar conferences. The total of 1462 papers and 246 posters presented at t…
This brief explores current research on dynamic spectrum auctions, focusing on fundamental auction theory, characteristics of the spectrum market, spectrum auction architecture and possible auction mechanisms. The brief explains how dynamic spectrum auctions, which enable new users to gain spectrum access and existing spectrum owners to obtain financial benefits, can greatly improve spectrum ef…
Systems are everywhere and we are surrounded by them. We are a complex amalgam of systems that enable us to interact with an endless array of external systems in our daily lives. They are electrical, mechanical, social, biological, and many other types that control our environment and our well-being. By appreciating how these systems function, will broaden our understanding of how our world wor…
This book extends the discussion of the nature of freedom and what it means for a human to be free. This question has occupied the minds of thinkers since the Enlightenment. However, without exception, every one of these discussions has focused on the character of liberty on Earth. In this volume the authors explore how people are likely to be governed in space and how that will affect what …
The karstic caves are favorable sites for tectonic events detecting, representing a conservative medium of three-dimensional framework where the tectonic deformations are well preserved. They also provide an environment conducive to dating and determining the geometrical parameters of past seismotectonic events. During the last three decades the study of dynamic tectonics and recent geodynamics…
Private Charles Smith had been dead for close to a century when Jonathan Hart discovered the soldier’s small diary in the Baldwin Collection at the Toronto Public Library. The diary’s first entry was marked 28 June 1915. After some research, Hart discovered that Charles Smith was an Anglo-Canadian, born in Kent, and that this diary was almost all that remained of this forgotten man, who lik…
This book deals with dynamic and stochastic methods for multi-project planning. Based on the idea of using queueing networks for the analysis of dynamic-stochastic multi-project environments this book addresses two problems: detailed scheduling of project activities, and integrated order acceptance and capacity planning. In an extensive simulation study, the book thoroughly investigates existin…
This book is based upon three interrelated open naturalistic studies conducted to better characterise the motivational orientation of students in higher education. Open semi-structured individual interviews were conducted with undergraduates, students at community colleges and students in taught postgraduate courses in Hong Kong. The analysis used an exploratory grounded theory approach and res…
