The subject of Signals and Systems is enormously complex, involving many concepts such as signals, mathematics and filter design that are woven together in an intricate manner. To cope with this scope and complexity, many Signals and Systems texts are often organized around the "numerical examples" of a system. With such organization, students can see through the complexity of Signals and Systems, they can learn about the distinct concepts and protocols in one part of the communication system while seeing the big picture of how all parts fit together. From a pedagogical perspective, our personal experience has been that such approach indeed works well. Based on the Authors extensive experience of teaching and research, the book is written with such a reader in mind. The Book is intended for a course on signals & systems at the senior undergraduate level and above. The authors consider all the requirements and tools used in analysis and design of discrete time systems for filter design and signal processing. Key features of the International Edition: * The extensive use of MATLAB based examples to illustrate how to solve the signals & systems problems. The textbook includes a wealth of problems with solutions. * Worked-out examples have been included to explain new and difficult concepts and to expose the reader to real-life signal processing problems. The inclusion of FIR and IIR filter design further enriches the contents of the book.

Oxidative stress and neuroinflammation are considered causative factors in various neurological disorders such as Parkinson’s and Alzheimer’s diseases. Antioxidants are chemicals that bind with oxidative species and nullify their effect from causing damage to biological molecules. Endogenous antioxidants are produced by our body, however most of them are obtained from external sources, primarily through diet, called dietary antioxidants. Major sources of antioxidants are brightly colored fruits, vegetables, cereals, legumes, and herbs. Other very effective sources are berries, green tea, and dark chocolate. These compounds have the potential to hinder neurodegeneration, reduce neuronal death and improve memory as well as cognitive functions. Based on the complex nature of antioxidants and oxidative stress, particular antioxidants such as vitamin E, vitamin C or β-carotene are beneficial in protecting cells, organs and tissues against oxidative damage. The Role of Natural Antioxidants in Brain Disorders describes various neuroprotective effects and their physiological phenomenon mediated by antioxidants to maintain and regulate the general health biomarkers against brain disorders. The important role of antioxidants, diet and lifestyle in managing brain disorders is covered, as is their use in conjunction with conventional therapies against oxidative stress. Both exogenous and endogenous antioxidants are explored in full. By focusing on the role of oxidative stress as a triggering mechanism for various brain disorders and the use of antioxidant foods in conjunction with traditional therapies in combating and preventing them, this is a valuable source for researchers in food science, nutrition, health science and physiology.

Mobile communication systems rely on radiofrequency waves to operate. Given the popularity and ubiquity of mobile communication devices as well as network densification, the level of Electromagnetic Field (EMF) exposure to the public is expected to rise significantly over the next few years. Although there is no clear evidence linking short-term exposure to EMF emission from wireless communication systems with adverse health effects, the International Agency for Research on Cancer (IARC) has concluded that EMF radiation is possibly carcinogenic. To cope with the concerns of the general public, the European Environmental Agency has recommended non-technical precautionary approaches to minimize exposure to EMF emissions. Rather than relying on these non-technical approaches, EMF, latency, network resilience and connection density, alongside traditional criteria such as spectral efficiency and energy efficiency are expected to take centre stage in the development of 5G systems. This book focuses on innovative EMF exposure research for future generations of mobile and wireless communications. This timely publication highlights the novel work done on reducing EMF emissions in future mobile communication systems and how to develop smart integrated technical solutions.

The efficient and satisfactory operation of all these densely deployed networks hinges on a suitable backhaul and fronthaul provisioning. The research community is working to provide innovative technologies with extensive performance evaluation metrics along with the required standardisation milestones, hardware and components for a fully deployed network by 2020 and beyond. Access, Fronthaul and Backhaul Networks for 5G & Beyond provides an overview from both academic and industrial stakeholders of innovative backhaul/fronthaul solutions. Covering a wide spectrum of underlying themes ranging from the recent thrust in edge caching for backhaul relaxation to mmWave-based fronthauling for radio access networks, this book is essential reading for engineers, researchers, designers, architects, technicians, students and service providers in the field of networking, mobile and wireless and computing technologies working towards the deployment of 5G networks.

Gillsbury may seem like any other typical, closeted American small town about to be forced to come to terms with a new LGBT social club formed in the town's only high school. Alain and his lovely Angels will be the pioneers to this revolutionary movement dragging the townspeople kicking and screaming along the way as they all fight their own inner demons. His final year in high school brings new friendship, hope, heartache, lies, deceit and murder all in the name of equality, acceptance and maybe even love.
