Taschenbuch. Zustand: Neu. Neuware - Epilepsy is a common neurological disease that can affect all ages. Although the majority of people with epilepsy can have excellent seizure control with medication, about 30% will fail anti-epileptic drugs. For those with medically intractable epilepsy, recurrent seizures lead to elevated mortality and injury risks, and the seizures themselves are socially disabling. Fortunately, for many people with intractable epilepsy, epilepsy can be cured or seizures better controlled with surgery. Localization of the seizure focus followed by surgical resection provide the best opportunities to cure epilepsy. Having a better understanding of the neuro-anatomy and physiology of epilepsy improves our ability to define the epileptic network and effectively treat epilepsy. Minimal access surgical approaches result in more rapid recovery from surgery, less pain, and more satisfied patients. For individuals without an opportunity to cure their epilepsy, new and emerging technologies can improve their quality of life by preventing injuries and reducing seizure frequency and severity. This Special Issue will highlight advances in the diagnosis and surgical treatment of epilepsy, including imaging and electroencephalography (EEG) approaches to defining the epileptic focus, understanding the epileptic network, and characterizing the anatomical substrate of epilepsy.

Our lives are being transformed by the interplay between mobile networks, wireless communications, and artificial intelligence. This transformation is an outcome of the emerging Internet of Things (IoT) concept and advancements in computer architecture that translate into high computing power, high-performance processing, and huge memory capacities. In addition to the IoT, cyber-physical systems aim for the seamless integration of physical systems with computing and communication resources. Furthermore, in urban areas, the integration of 'software-defined sensor networks' and 'sensing as a service' concepts with legacy WSN-based systems is leading to the transformation of conventional city services towards smart cities. Smart energy, smart driving, smart homes, smart living, smart governance, and smart health are just a few services that smart cities can offer. This book focuses on novel solutions for wireless sensor and actuator networks in smart cities. This Special Issue invites academic and industry researchers in computer science and engineering, electrical engineering, and communication engineering, as well as ICT industry engineers and practitioners, to contribute original articles in all aspects of wireless sensor networks and actuator systems for smart cities.

[Recent advances in sensing technologies, especially those for Microsensor Integrated Systems, have led to several new commercial applications. Among these, low voltage and low power circuit architectures have gained growing attention, being suitable for portable long battery life devices. The aim is to improve the performances of actual interface circuits and systems, both in terms of voltage mode and current mode, in order to overcome the potential problems due to technology scaling and different technology integrations. Related problems, especially those concerning parasitics, lead to a severe interface design attention, especially concerning the analog front-end and novel and smart architecture must be explored and tested, both at simulation and prototype level. Moreover, the growing demand for autonomous systems gets even harder the interface design due to the need of energy-aware cost-effective circuit interfaces integrating, where possible, energy harvesting solutions. The objective of this Special Issue is to explore the potential solutions to overcome actual limitations in sensor interface circuits and systems, especially those for low voltage and low power Microsensor Integrated Systems.

Please describe the book in straightforward and consumer-friendly terms.[Real-time and networked embedded systems are important bidirectional bridges between the physical and the information worlds. Embedded intelligence is increasingly pervading industry, infrastructure, and public and private spaces, being identified as an emerging societal and economic 'neural system' that supports both societal changes and economic growth. As cost/performance improves, objects connected in everyday life increasingly rely on embedded intelligence in an ever-growing array of application fields, specialized technologies, and engineering disciplines. While this process gradually builds the IoT, it exposes a series of specific non-trivial timing and other extra-functional requirements and system properties that are less common in other computing areas. The ten articles in this book propose solutions to the specific open problems of cyber-physical and real-time embedded systems applicable to both traditional application domains, such as industrial automation and control, energy management, automotive, aerospace and defense systems, as well as emerging domains, such as medical devices, household appliances, mobile multimedia, gaming, and entertainment systems.].

Taschenbuch. Zustand: Neu. Neuware - Nowadays, we meet microsystems in a variety of devices used in modern life. They are used, for example, in medicine, biology, industry, home appliances, transport, and aerospace. One of the main problems in the technological development of microsystems is their actuation. Several solutions have been suggested, such as electrostatic, electrothermal, electromagnetic, or piezoelectric actuation, although a valid solution seems to be still out of our reach. Another crucial problem in designing, manufacturing, and operating microsystems for micromanipulation consists in the loss of some basic paradigms commonly used as a source of inspiration at the macroscale. The differences in designing at the two different scales may have either positive or negative effects. For example, an unthinkable structure in the day-life domain, as, for example, a long 'cantilever' bridge over the Hudson river, would become possible after downscaling 'everything' from road dimensions to the micro-world. Alternatively, a fantastic electric motor that works very well in our world, by virtue of the basic principles of electromagnetism, would become useless if scaled back to the micro cosmos. This book opens a small window on the world of research, presenting a group of papers that try to respond to the challenge of increasing the efficiency and functionality of modern microsystems. A final little section is also dedicated to the development of new teaching methods successfully adopted in some university courses.

Taschenbuch. Zustand: Neu. Neuware - Most freshwater aquatic ecosystems have focused on open-water conditions, during spring, summer, and autumn. Studies in winter during ice-covered conditions are sparse due to the logistic difficulties of sampling during freezing weather and the assumption that these ecosystems are biologically inactive during winter. There is growing evidence, however, that ice conditions can have strong impacts on the flora, fauna, and water quality of freshwater systems, dependent on the severity and duration of the winter season. The magnitude of winter conditions and the duration of the ice-covered period can also set the stage of the biological succession of flora, fauna and water-quality constituents in the subsequent spring and summer seasons (e.g., higher probability of early algal blooms with earlier ice-off dates). Climate change and changes in the type and degree of anthropogenic impacts will also influence the ice regime and hence the ecosystems of northern freshwater systems. This Special Issue provides a venue to report new findings in field-based and modelling research to highlight the importance of the ice regime and ice-induced hydraulic regime of rivers and lakes on their aquatic ecosystems.

Taschenbuch. Zustand: Neu. Neuware - 3D printing has revolutionized the microfabrication prototyping workflow over the past few years. With the recent improvements in 3D printing technologies, highly complex microfluidic devices can be fabricated via single-step, rapid, and cost-effective protocols as a promising alternative to the time consuming, costly and sophisticated traditional cleanroom fabrication. Microfluidic devices have enabled a wide range of biochemical and clinical applications, such as cancer screening, micro-physiological system engineering, high-throughput drug testing, and point-of-care diagnostics. Using 3D printing fabrication technologies, alteration of the design features is significantly easier than traditional fabrication, enabling agile iterative design and facilitating rapid prototyping. This can make microfluidic technology more accessible to researchers in various fields and accelerates innovation in the field of microfluidics. Accordingly, this Special Issue seeks to showcase research papers, short communications, and review articles that focus on novel methodological developments in 3D printing and its use for various biochemical and biomedical applications.

Taschenbuch. Zustand: Neu. Neuware - The engineering and utilization of biocomposites is a research field of major scientific and industrial interest worldwide. The biocomposite area is extensive and spans from structured and solid biocomposites (e.g., reinforced bioabsorbable polymers), films (e.g., antimicrobial barriers), to soft biocomposites (e.g., use of alginates, collagen and nanocellulose as components in bioinks for 3D bioprinting). Key aspects in this respect are the appropriate engineering and production of biomaterials, nanofibres, bioplastics, their functionalization enabling intelligent and active materials, processes for effective manufacturing of biocomposites and the corresponding characterization for understanding their properties.The current Special Issue emphasizes the bio-technological engineering of novel biomaterials and biocomposites, considering also important safety aspects in the production and use of bio- and nanomaterials.

Taschenbuch. Zustand: Neu. Neuware - Power transformers are key components in electric power distribution and transmission systems, and it is essential that they function properly for many years. With increasing age, there are potential risks of extremely high monetary losses due to unexpected failures and outages. A simple solution would be to replace all aging and risky transformers at once with new ones. Such an approach is obviously not a fiscally realistic solution. The main objectives are to extend their service life and optimize their performance through increased availability. For these reasons, in the past decades transformer life management has gained an ever-increasing interest. The greatest challenges are related to the need for methods to assess their condition and life expectancy along with the improvement of transformers' efficiency by noble designs and/or the application of new materials. This book covers some theoretical and practical developments with special emphasis on R&D trends in transformer diagnostics and monitoring. Graduate-level students and academics as well as scientists and engineers involved in power equipment design, diagnostics, and monitoring will benefit from this book.

Taschenbuch. Zustand: Neu. Neuware - The proposed existence of the edge and screw dislocation in the 1930s, and the subsequent work showing that dislocation theory could explain the plastic deformation of crystals, represent an important step in developing our understanding of materials into a science. The continued work involved with characterization of dislocations and linking them to a variety of physical properties in both single and poly crystals have made enormous progress over the past 50 years. It is rare to find a technical application involving a material with any crystal structure that is not impacted by dislocations; mechanical properties, massive phase transformations, interphases, crystal growth, electronic properties, the list goes on. In many systems the properties is controlled by the formation of partial dislocations separated by a stacking fault; for example plastic deformation via deformation twinning. And finally, giant strides have been made in characterization and modeling of systems containing dislocations. The Special Issue on 'Crystal Dislocations' is intended to provide a unique international forum aimed at covering a broad range of results involving dislocations and their importance on crystal properties and crystal growth. Scientists working in a wide range of disciplines are invited to contribute to this cause. Dr. K. Peter D. Lagerlof, Associate Professor of CeramicsGuest Editor.

Please describe the book in straightforward and consumer-friendly terms.The use of polymeric materials from renewable resources dates back in history. Even though synthetic polymers dominated the market for years, there is now a need for the development of sustainable, safe, and environmentally benign plastics from renewable resources.Green polymers from renewable resources can be isolated from biomass, obtained through the chemical modification of natural polymers, or synthesized through a two-step process from biomass involving monomer synthesis and then polymerization. Finally, polymer synthesis can be achieved in plants through photosynthesis using carbon dioxide or in microorganisms (e.g. synthesis of poly(hydroxy-alkanoate)s).In this issue, the developments in sustainable polymers including PLA, PHB, and furan-based materials are presented together with those concerning bionanocomposites of lignocellulosic mater or starch, and blends of bioplastics. The use of biomass-based plasticizers, fillers, and additives for the improvement of polymers' properties and the applications of biopolymers such as hyaluronic acid, carrageenans, chitosan, and polysaccharides in medicine and pharmaceutics are discussed.
