Forming Processes of Modern Metallic Materials
The plastic forming of metallic materials is the most efficient and an important manufacturing technology in today's industry. Lightweight materials, such as titanium alloys, aluminum alloys, and ultra-high-strength steels, are used extensively in the automotive, aerospace, transportation, and construction industries, leading to increased demand for advanced innovative forming technologies. Today, numeric simulations are highly focused and provide a better understanding of the innovative forming processes. Computational methods and numerical analysis coupled with the modelling of the structural evolution allow us to reduce time costs and eliminate experimental tests. The subjects of research articles published in this nook are multidisciplinary, including friction and lubrication in sheet metal forming, hot strip rolling and tandem strip rolling, application of numeric methods to simulate metal forming processes, development of new creep performance materials, the single point incremental forming process, and the fatigue fracture characteristics of Alclad 7075-T6 aluminum alloy sheets joined by refill friction stir spot welding. Review articles summarize the approaches on the innovative numerical algorithms, experimental methods, and theoretical contributions that have recently been proposed for sheet metal forming by researchers and business research centers.
A Singular Remedy
Stefanie G瓣nger explores how medical knowledge was shared across societies tied to the Atlantic World between 1751 and 1820. Centred on Peruvian bark or cinchona, G瓣nger shows how that remedy and knowledge about its consumption - formulae for bittersweet, 'aromatic' wines, narratives about its discovery or beliefs in its ability to prevent fevers - were understood by men and women in varied contexts. These included Peruvian academies and Scottish households, Louisiana plantations and Moroccan court pharmacies alike. This study in plant trade, therapeutic exchange, and epistemic brokerage shows how knowledge weaves itself into the fabric of everyday medical practice in different places.

Facebooking the Anthropocene in Raja Ampat
Facebooking the Anthropocene in Raja Ampat is a deeply intimate look at the cataclysmic shifts between humans, technology, and the so-called natural world. Amid the breakneck pace of both technological advance and environmental collapse, Robert Ostertag explores how we ourselves are changing as fast as the world around us--from how we make music, to how we have sex, to what we do to survive, and who we imagine ourselves to be. And though the environmental crisis terrifies and technology overwhelms, Ostertag finds enough creativity, compassion, and humor in our evolving behavior to keep us laughing and inspired as the world we are building overtakes the world we found. A true polymath who covered the wars in Central America during the 1980s, recorded dozens of music projects, and published books on startlingly eclectic subjects, Ostertag fuses his travels as a touring musician with his journalist's eye for detail and the long view of a historian. Wander both the physical and the intellectual world with him. Watch Buddhist monks take selfies while meditating and DJs who make millions of dollars pretend to turn knobs in front of crowds of thousands. Shiver with families huddling through the stinging Detroit winter without heat or electricity. Meet Spice Islanders who have never seen flushing toilets yet have gay hookup apps on their phones. Our best writers have struggled with how to address the catastrophes of our time without looking away. Ostertag succeeds where others have failed, with the moral acuity of Susan Sontag, the technological savvy of Lewis Mumford, and the biting humor of Jonathan Swift.

High Voltage Engineering
In AC transmission, low voltages are below 11 KV and medium voltages are in the range of 22 KV to 66 KV. The voltages 132 KV, 169KV, 220 KV and 275 KV are termed as High voltages. Above 132 KV to 750KV are Extra High Voltages (EHV). Above 750 KV voltages are called as Ultra High Voltage (UHV). The application like electron microscope and X -ray unit required high voltage of order of 100 KV or more. Electrostatic precipitators, particles accelerator in nuclear physics, etc. require high voltage dc of KV. High voltage of one million voltage or even more required for testing power apparatus rated EHV (400 KV system and above). High impulse voltages are required for testing purpose to stimulate overvoltage that occurs in power system due to lightning or switching action.This laboratory manual is useful for undergraduate & postgraduate students of Electrical Engineering to perform experiments to determine the parameters, effect & measurements etc. related to high voltage engineering.
Light weight aggregate concrete with sawdust and brick ballast
Construction industry relies heavily on conventional material such as cement, sand and gravel for the production of concrete. The river sand and gravels which are most commonly used as fine aggregates and coarse aggregates respectively in the production of concrete, poses the problem of acute shortage in many areas, whose continued use has started posing serious problem with respect to its availability, cost and environmental impact. An attempt is being made in this project to use the locally available waste materials to replace the river sand and gravels to produce light weight and low cost concrete. Sawdust and Brick ballast are easily affordable at low cost or free of cost, which are partially replaced with river sand and gravels respectively for making concrete. Sawdust can be defined as loose particles or wood chippings attained as by products from the sawing of timber into standard useable sizes. Brick ballast is common in the form of over burned bricks. Natural sand and Gravels were partially replaced with sawdust and broken brick ballast respectively.
Microelectrode Arrays and Application to Medical Devices
Microelectrode arrays are increasingly used in a wide variety of situations in the medical device sector. For example, one major challenge in microfluidic devices is the manipulation of fluids and droplets effectively at such scales. Due to the laminar flow regime (i.e., low Reynolds number) in microfluidic devices, the mixing of species is also difficult, and unless an active mixing strategy is employed, passive diffusion is the only mechanism that causes the fluid to mix. For many applications, diffusion is considered too slow, and thus many active pumping and mixing strategies have been employed using electrokinetic methods, which utilize a variety of simple and complex microelectrode array structures. Microelectrodes have also been implemented in in vitro intracellular delivery platforms to conduct cell electroporation on chip, where a highly localized electric field on the scale of a single cell is generated to enhance the uptake of extracellular material. In addition, microelectrode arrays are utilized in different microfluidic biosensing modalities, where a higher sensitivity, selectivity, and limit-of-detection are desired. Carbon nanotube microelectrode arrays are used for DNA detection, multi-electrode array chips are used for drug discovery, and there has been an explosion of research into brain-machine interfaces, fueled by microfabricated electrode arrays, both planar and three-dimensional. The advantages associated with microelectrode arrays include small size, the ability to manufacture repeatedly and reliably tens to thousands of micro-electrodes on both rigid and flexible substrates, and their utility for both in vitro and in vivo applications. To realize their full potential, there is a need to develop and integrate microelectrode arrays to form useful medical device systems. As the field of microelectrode array research is wide, and touches many application areas, it is often difficult to locate a single source of relevant information. This Special Issue seeks to showcase research papers, short communications, and review articles, that focus on the application of microelectrode arrays in the medical device sector. Particular interest will be paid to innovative application areas that can improve existing medical devices, such as for neuromodulation and real world lab-on-a-chip applications.
Cast Irons
The demand for cast iron components, with weights ranging from a few kilograms to several tons, has increased significantly in recent years, both for technical and economic reasons. In fact, the lower cost compared to other alloys, and the good castability, which allow one to obtain near-net shape components in as-cast conditions, and the mechanical properties that can be obtained, are just some of the motivations that attract mechanical designers. However, correct design requires a good knowledge of the intrinsic correlation among alloy chemical composition, process parameters, microstructure (with casting defects) and mechanical properties. This book is aimed at collecting excellent and recent research experimental and theoretical works in this filed. Technological (say, wear resistance and weldability) and mechanical properties (say, Young modulus, static and fatigue strength) of different grades of cast irons, ranging from solution strengthened ferritic ductile iron to compacted graphite iron as well as white and nodular cast irons, are correlated with the alloy chemical composition, process parameters and casting dimension.

Deep Learning for Facial Informatics
Deep learning has been revolutionizing many fields in computer vision, and facial informatics is one of the major fields. Novel approaches and performance breakthroughs are often reported on existing benchmarks. As the performances on existing benchmarks are close to saturation, larger and more challenging databases are being made and considered as new benchmarks, further pushing the advancement of the technologies. Considering face recognition, for example, the VGG-Face2 and Dual-Agent GAN report nearly perfect and better-than-human performances on the IARPA Janus Benchmark A (IJB-A) benchmark. More challenging benchmarks, e.g., the IARPA Janus Benchmark A (IJB-C), QMUL-SurvFace and MegaFace, are accepted as new standards for evaluating the performance of a new approach. Such an evolution is also seen in other branches of face informatics. In this Special Issue, we have selected the papers that report the latest progresses made in the following topics: 1. Face liveness detection 2. Emotion classification 3. Facial age estimation 4. Facial landmark detection We are hoping that this Special Issue will be beneficial to all fields of facial informatics.

Smart Management of Conservative, Organic and Integrated Agriculture
Sustainable agriculture aims to achieve the goal of food security, also maximizing the socio-economic benefits, and minimizing environmental drawbacks. Farming systems mostly relying on ecological processes and the reduced application of external inputs (fertilizers and pesticides), such as organic farming and integrated farming, can even contribute to the mitigation of global warming and of the desertification of soils. Conservation agriculture (CA) is also widely recognized as a farming system able to preserve soils from erosion and nutrient loss, increase soil organic matter and carbon sink capacity, and improve biological and physical fertility. Nevertheless, CA systems generally rely on the large use of agrochemicals (above all, herbicides and fertilizers) in order to sustain crop production, with negative consequences in terms of energy efficiency and environmental impact. This also does not enable an easy transfer of CA techniques into organic and integrated farming systems, a combination that might enhance the environmental benefits of these farming systems. In this regard, this Special Issue deals with the "Smart Management of Conservative, Organic, and Integrated Agriculture". We invited experts and researchers to contribute with original researches, reviews, and opinion pieces covering all topics related to organic, integrated, and conservative farming systems. The published articles concern with the most important aspects of these innovative systems, such as performances of farm machinery and agro-ecological strategies aiming at sustaining crop production whilst reducing the need for agrochemicals.

Introduction and Scope-During the last few decades, an enormous effort has been made to understand corrosion phenomena and their mechanisms, and to elucidate the causes that dramatically influence the service lifetime of metal materials. The performance of metal materials in aggressive environments is critical for a sustainable society. The failure of the material in service impacts the economy, the environment, health, and society. In this regard, corrosion-based economic losses due to maintenance, repair, and the replacement of existing structures and infrastructure account for up to 4% of gross domestic product (GDP) in well developed countries. One of the biggest issues in corrosion engineering is estimating service lifetime. Corrosion prediction has become very difficult, as there is no direct correlation with service lifetime and experimental lab results, usually as a result of discrepancies between accelerated testing and real corrosion processes. It is of major interest to forecast the impact of corrosion-based losses on society and the global economy, since existing structures and infrastructure are becoming old, and crucial decisions now need to be made to replace them. On the other hand, environmental protocols seek to reduce greenhouse effects. Therefore, low emission policies, in force, establish regulations for the next generation of materials and technologies. Advanced technologies and emergent materials will enable us to get through the next century. Great advances are currently in progress for the development of corrosion-resistant metal materials for different sectors, such as energy, transport, construction, and health. This Special Issue on the corrosion and protection of metals is focused on current trends in corrosion science, engineering, and technology, ranging from fundamental to applied research, thus covering subjects related to corrosion mechanisms and modelling, protection and inhibition processes, and mitigation strategies.
Energy management and real-time scheduling for the Internet of Things
Energy harvesting systems should be designed to function perpetually without any human intervention because either costly or impractical. The introduction of energy harvesting capabilities into the IoT introduces a lot of design questions. Researchers strive to design efficient power managementand scheduling techniques which additionally adapt to real-time requirements that characterize a lot of energy harvesting computing systems present in the IoT. In this book, we particularly address the scheduling issue for uniprocessor architectures. We consider a self-powered system which has to execute, from one hand aperiodic tasks with minimal responsiveness, and from the other hand hard deadline periodic tasks. Classical scheduling techniques need to be reconceived so as to take into account the fluctuating energy source. The book describes novel aperiodic task servers which are energy harvesting aware. Extensive results of simulations are reported so as to bring to light the effectiveness of two aperiodic task servers: a Slack Stealing one and a Total Bandwidth one.

Foamed Cement Formulation For Oil & Gas Wells Casing-Liner Cement Job
Cementing the casing and liner in the oil and gas wells is an important and critical section of drilling operations. Particularly, as the conventional cements have a high range of density, cementing jobs in some cases such as in a low pressure, depleted, or highly fractured reservoir is so critical operation. The high density of slurry in the well could cause severe formation damage by its high column hydraulic pressure. Therefore, lightweight and ultra-lightweight cements would be the solution for these conditions. One of the innovations in ultra-lightweight cements designing is Foamed Cement. In the current book, an experimental approach for appropriate foamed cement designing (its slurry and set-cement characteristics) has been introduced. The vast information about casings and liners cementing and its process, drilling cements and their additives and standard procedures for various tests on these cements have been explained. The standard API and ISO tests for formulating a foamed cement for oil and gas wells cementing jobs have been described. Also, you can access the latest and cutting edge researches on oil and gas wells foamed cementing operations by reading this book.
