Mobile and Ubiquitous Systems: Computing, Networking and Services
This book constitutes the refereed post-conference proceedings of the 19th International Conference on Mobile and Ubiquitous Systems: Computing, Networking and Services, MobiQuitous 2022, which was held in Pittsburgh, November 14-17, 2022. The conference was held virtually due to the COVID-19 pandemic. The 26 full and 2 short papers were carefully reviewed and selected from 95 submissions and present discussions, They were organized in topical sections as follows: Internet of Things (IoT), Security and Privacy, Human-centric sensing, Drone applications and edge computing, Wireless networks, Mobile and human computer interactions, Poster and demo sessions, Technology for health
Antennas and Wave Propagation
Antennas and radio propagation are continuously and rapidly evolving and new challenges arise every day. As a result of these rapid changes the need for up-to-date texts that address this growing field from an interdisciplinary perspective persists. This book, organized into nine chapters, presents new antenna designs and materials that will be used in the future, due to the trend for higher frequencies, as well as a bird's eye view of some aspects related to radio propagation channel modeling. The book covers the theory but also the practical aspects of technology implementation in a way that is suitable for undergraduate and graduate-level students, as well as researchers and professional engineers.
Multi-Elliptical Geometry of Scatterers in Modeling Propagation Effect at Receiver
In the proposed chapter, the authors present a geometric-statistical propagation model that defines three groups of received signal components, id est, direct path, delayed scattering, and local scattering components. The multi-elliptical propagation model, which represents the geometry of scatterer locations, is the basis for determining the delayed components. For the generation of the local components, a statistical distribution is used. The basis for this model is a power angular spectrum (PAS) of the received signal, which is closely related to a type of propagation environment and transmitter-receiver spatial positions. Therefore, we have an opportunity to evaluate the influence of the environment type and an object motion direction on the basic characteristics such as envelope distribution, PAS, autocorrelation function, and spectral power density. The multi-elliptical model considers the propagation phenomena occurring in the azimuth plane. In the chapter, we will also show the 3D extension of modeling effects of propagation phenomena.
Digital Transformation, Cyber Security and Resilience
This volume constitutes revised and selected papers presented at the First International Conference on Digital Transformation, Cyber Security and Resilience, DIGILIENCE 2020, held in Varna, Bulgaria, in September - October 2020. The 17 papers presented were carefully reviewed and selected from the 119 submissions. They are organized in the topical sections as follows: cyber situational awareness, information sharing and collaboration; protecting critical infrastructures and essential services from cyberattacks; big data and artificial intelligence for cybersecurity; advanced ICT security solutions; education and training for cyber resilience; ICT governance and management for digital transformation.

My Opposition
This is a truly unique account of Nazi Germany at war and of one man's struggle against totalitarianism. A mid-level official in a provincial town, Friedrich Kellner kept a secret diary from 1939 to 1945, risking his life to record Germany's path to dictatorship and genocide and to protest his countrymen's complicity in the regime's brutalities. Just one month into the war he is aware that Jews are marked for extermination and later records how soldiers on leave spoke openly about the mass murder of Jews and the murder of POWs; he also documents the Gestapo's merciless rule at home from euthanasia campaigns against the handicapped and mentally ill to the execution of anyone found listening to foreign broadcasts. This essential testimony of everyday life under the Third Reich is accompanied by a foreword by Alan Steinweis and the remarkable story of how the diary was brought to light by Robert Scott Kellner, Friedrich's grandson.
Compound Semiconductor Electronics, The Age Of Maturity
In many respects, compound semiconductor technology has reached the age of maturity when applications will have been defined, yields are high enough and well established, and gallium arsenide and related compounds have carved many important niches in electronics. This book reviews the state-of-the-art of compound semiconductor electronics. It covers the microwave, millimeter wave, and submillimeter wave devices, monolithic microwave and digital integrated circuits made from compound semiconductors and emerging wide band semiconductor materials. The book is written by leading experts in compound semiconductor electronics from industry and academia and strikes the balance between practical applications, record-breaking results, and design and modeling tools specific for compound semiconductor technology. Engineers, scientists, and graduate students working in solid state electronics and especially in the area of compound semiconductor electronics will find this book very useful. It could also be used as a text or a supplementary text for graduate courses in this field.
