Development and Applications of Negative Ion Sources (Springer Series on Atomic, Optical, and Plasma Physics #125)
by Vadim DudnikovThis book describes the development of sources of negative ions and their application in science and industry. It describes the physical foundations and implementation of the key methods of negative ion production and control, such as charge exchange, thermionic emission, plasma volume, secondary emission (sputtering) and surface-plasma sources, as well as the history of their development. Following on from this essential foundational material, the book goes on to explore transport of negative ion beams, and beam-plasma instabilities. Now in its second edition, the book has been substantially expanded and updated to address the many developments since it was first published, most importantly the development and investigation of cesiated surfaces with work function ~1.2-1.3 eV in conditions close to discharges in surface plasma sources. The book also includes a new chapter on development of conversion targets for high-energy neutral beam injectors, covering gas targets, plasma targets and photon targets for efficient conversion of high energy negative ion beams to neutral beams.With exposition accessible at the graduate level, and a comprehensive bibliography, this book will appeal to all students and researchers whose work concerns ion sources and their applications to accelerators, beam physics, storage rings, cyclotrons, and plasma traps.
Development and Characterization of a Dispersion-Encoded Method for Low-Coherence Interferometry
by Christopher TaudtThis Open Access book discusses an extension to low-coherence interferometry by dispersion-encoding. The approach is theoretically designed and implemented for applications such as surface profilometry, polymeric cross-linking estimation and the determination of thin-film layer thicknesses. During a characterization, it was shown that an axial measurement range of 79.91 µm with an axial resolution of 0.1 nm is achievable. Simultaneously, profiles of up to 1.5 mm in length were obtained in a scan-free manner. This marked a significant improvement in relation to the state-of-the-art in terms of dynamic range. Also, the axial and lateral measurement range were decoupled partially while functional parameters such as surface roughness were estimated. The characterization of the degree of polymeric cross-linking was performed as a function of the refractive index. It was acquired in a spatially-resolved manner with a resolution of 3.36 x 10-5. This was achieved by the development of a novel mathematical analysis approach.

Development and Disaster Management: A Study of the Northeastern States of India
by Amita Singh Milap Punia Nivedita P. Haran Thiyam Bharat SinghThis book highlights the relationship between disasters and development through a socio-cultural study of human geography and governance institutions. It studies the cause, context and consequences of disasters in one of the most fragile Himalayan regions in India. The book establishes the fact that disaster management is built within the framework of good governance, without which it has no meaning. For lack of effective and responsive governance, development has lagged behind and even though the frequency of disasters has been increasing, little is being done to redesign developmental frameworks to prevent ensuing losses. Besides, the near absence of governmental support during recurrent disasters, communities have cumulatively become reservoirs of innovations to cope up with disasters. The resilience plans need not follow implanted models but may be cost effective only if they apply a bottom up approach. Just as the region is culturally diverse so are the challenges encountered by local communities in terms of generating resilience to every disaster. Despite more than a decade of the Disaster Management Act (DMA) of 2005, most of the states in this northeastern fringe of India continue to wait for its implementation beyond mere structures and offices. The book suggests that urgent action is required in accordance with the DMA 2005 towards inter-agency coordination, proactive participation of local governance, mobilization of Community based Organizations (CBOs) and curriculum based training in every academic and technical institution. Governments of these northeastern states of India should establish accountability of State Disaster Management Authorities and inspire them to participate proactively with communities for an effective resilience building in the region.

Development and Testing of Navigation Algorithms for Autonomous Underwater Vehicles (Springer Theses)
by Francesco FanelliThis book focuses on pose estimation algorithms for Autonomous Underwater Vehicles (AUVs). After introducing readers to the state of the art, it describes a joint endeavor involving attitude and position estimation, and details the development of a nonlinear attitude observer that employs inertial and magnetic field data and is suitable for underwater use. In turn, it shows how the estimated attitude constitutes an essential type of input for UKF-based position estimators that combine position, depth, and velocity measurements. The book discusses the possibility of including real-time estimates of sea currents in the developed estimators, and highlights simulations that combine real-world navigation data and experimental test campaigns to evaluate the performance of the resulting solutions. In addition to proposing novel algorithms for estimating the attitudes and positions of AUVs using low-cost sensors and taking into account magnetic disturbances and ocean currents, the book provides readers with extensive information and a source of inspiration for the further development and testing of navigation algorithms for AUVs.
Development and Testing of Vehicle Software and its Influence on Sustainable Transport
by Antonio Colmenar-Santos David Borge-Diez Pedro-Miguel Ortega-CabezasThis book evaluates the contributions of the electronic control unit software of an electric vehicle on sustainability and society, such as the reduction of emissions during a product design and the improvements in the vehicle. A sustainable transport model is proposed, demonstrating its economic viability. By validating software in a more efficient way and adding new functionalities to the software to enhance driving efficiency, energy consumption can be significantly reduced. Therefore, software validation and development have a significant impact on sustainability. This book offers innovative validation solutions based on artificial intelligence techniques to reduce validation time and emissions. The impact of driving efficiency on sustainable transport models is studied in detail, making proposals to be considered in the current environmental policies under discussion within the European Union in order to improve the sustainability of transport models. Vehicles are becoming sophisticated electronic systems due to the fact that they are integrating a significant number of electronic control units. This trend will certainly continue in the year to come. Consequently, software validation techniques are a key element for car manufacturers in order to ensure the quality of the vehicle. This book contributes to these efforts.

Development and the Law: A Guide for Construction and Property Professionals
by Godfrey Bruce-RadcliffeA gap has long existed between construction professionals – such as architects, engineers, quantity surveyors and consultants – and the property development process. The underlying development structures, expressed in terms of legal obligation and accountability, are all too little understood. This practical guide by a highly experienced lawyer identifies the role of the construction professional in a wider context and looks beyond their relationship with their immediate employer. It provides the development professional with an understanding of the many relationships involved in projects, both in terms of contractual obligation and duty of care. This encourages more effective communication between those involved, including joint venture partners, bankers, funders, landowners with an interest in the outcome and tenants.
Development as Freedom in a Digital Age
by Bjã¶rn Sã¶ren GiglerUnder what conditions can new technologies enhance the well-being of poor communities? The study designs an alternative evaluation framework (AEF) that applies Amartya Sen's capability approach to the study of information and communications technologies (ICTs) in order to place people's well-being, rather than technology, at the center of the study. The AEF develops an impact chain that examines the mechanisms by which access to, and meaningful use of, ICTs can enhance people's "informational capabilities ? and improve people's human and social capabilities. This approach thus uses people's individual and collective capabilities, rather than measures of access or use, as its principal evaluative space. Based on empirical evidence from indigenous communities' use of new technologies in rural Bolivia, the study concludes that enhancing poor people's informational capabilities is the most critical factor determining the impact of ICTs on their well-being. Improved informational capabilities, like literacy, do enhance the human capabilities of poor and marginalized peoples to make strategic life choices and achieve the lifestyle they value. Evaluating the impact of ICTs in terms of capabilities thus reveals no direct relationship between improved access to, and use of, ICTs and enhanced well-being; ICTs lead to improvements in people's lives only when informational capabilities are transformed into expanded human and social capabilities in the economic, political, social, organizational, and cultural dimensions of their lives. The study concludes that intermediaries are bound to play a central, even fundamental, role in this process. They help poor communities to enact and appropriate ICTs to their local socio-cultural context so that their use becomes meaningful for people's daily lives, enhances their informational capabilities, and ultimately improves their human and social capabilities.

Development in Coastal Zones and Disaster Management (Disaster Research and Management Series on the Global South)
by Amita Singh Nivedita P. Haran R. Lalitha. S. FernandoIn the last two decades, coastal regions have relatively endured some of the fiercest oceanic and geophysical disasters than the earlier decades. Yet, disaster management governance fails to match the human, nonhuman and environmental calamity which is unfolding in its most frequent and unpredictable pattern. Between the Asian Tsunami of 2004 to the devastating Chennai and Kerala floods of 2018 the socio-industrial-livelihood impact alerts governments towards a greater and more serious compliance to laws for coastal conservation. The United Nations Office for Disaster Risk Reduction (UNDRR) in 2018 had shocking statistics to share as the deaths and damages related to only Tsunami disaster at the coasts to 251,770 and US$280 billions respectively in the last 20 years (1998-2017) as compared to 998 and US$ 2.7 billion in the previous 20 years (1978-1997). Coastal conservation is no more a question of casual governance but has become a need for survival. The region of South Asia which ranks much higher in its vulnerability, weak resilience and relatively undersupplied governance structures ought to take this responsibility on a priority. The spirit of Hyogu Declaration and the Sendai Framework for Action suggests preparedness and resilience building as key approach areas in coastal governance. The book is incomparable in its holistic and transdisciplinary social science based approach to disaster management which links conservation of marine flora and fauna, ecosystems and land management with decision making processes and coastal regulations. These grass root findings from the subcontinent are substantiated by a section on the most powerful court battle on the Kerala Floods as a guideline for readers to discerningly identify an ‘Act of God’ often used as a veil to hide lack of preparedness, apathy and political greed. This book becomes indispensable reading for anyone involved in research, administration or any level of decision making for the mitigation and prevention of disasters.

Development of 15 Micron Cutoff Wavelength HgCdTe Detector Arrays for Astronomy (Springer Theses)
by Mario CabreraThis thesis describes advances in the understanding of HgCdTe detectors. While long wave (15 μm) infrared detectors HgCdTe detectors have been developed for military use under high background irradiance, these arrays had not previously been developed for astronomical use where the background irradiance is a billion times smaller. The main pitfall in developing such arrays for astronomy is the pixel dark current which plagues long wave HgCdTe. The author details work on the success of shorter wavelength development at Teledyne Imaging Sensors, carefully modeling the dark current–reverse bias voltage curves of their 10 μm devices at a temperature of 30K, as well as the dark current–temperature curves at several reverse biases, including 250 mV. By projecting first to 13 and then 15 μm HgCdTe growth, values of fundamental properties of the material that would minimize tunneling dark currents were determined through careful modeling of the dark current-reverse bias voltage curves, as well as the dark current-temperature curves. This analysis was borne out in the 13 μm parts produced by Teledyne, and then further honed to produce the necessary parameters for the 15 μm growth. The resulting 13 μm arrays are being considered by a number of ground-based astronomy research groups.

Development of 6G Networks and Technology explores the benefits and challenges of 5G and beyond that play a key role in the development of the next generation of internet. 6G is targeted to improve download speeds, eliminate latency, reduce congestion on mobile networks, and support advancements in technology. 6G has the potential to transform how the human, physical, and digital worlds interact with each other and the capability to support advancements in technology, such as virtual reality (VR), augmented reality (AR), the metaverse, and artificial intelligence (AI). Machine learning and deep learning modules are also an integral part of almost all automated systems where signal processing is performed at different levels. Signal processing in the form text, image, or video needs large data computational operations at the desired data rate and accuracy. Large data requires more use of IC area with embedded bulk memories that lead to power consumption. Trade-offs between power consumption, delay, and IC area are always a concern of designers and researchers. Energy-efficient, high-speed data processing is required in major areas like biomedicine and healthcare, agriculture, transport, climate change, and national security and defense. This book will provide a foundation and initial inputs for researchers, scholars, and students working in the areas of wireless networks and high-speed data processing systems. It also provides techniques, tools, and methodologies to develop next-generation internet and 6G.
Development of Adaptive Speed Observers for Induction Machine System Stabilization (SpringerBriefs in Electrical and Computer Engineering)
by Yehia Sayed Mohammed Ahmed A. Diab Abo-Hashima M. Al-Sayed Hossam Hefnawy Abbas MohammedThis book describes the development of an adaptive state observer using a mathematical model to achieve high performance for sensorless induction motor drives. This involves first deriving an expression for a modified gain rotor flux observer with a parameter adaptive scheme to estimate the motor speed accurately and improve the stability and performance of sensorless vector-controlled induction motor drives. This scheme is then applied to the controls of a photovoltaic-motor water-pumping system, which results in improved dynamic performance under different operating conditions. The book also presents a robust speed controller design for a sensorless vector-controlled induction motor drive system based on H∞ theory, which overcomes the problems of the classical controller.

Development of Coherent Detector Technologies for Sub-Millimetre Wave Astronomy Observations
by Boon-Kok TanThe thesis describes the development of receiver technologies for sub-millimetre astronomy instruments, focusing on high performance coherent cryogenic detectors operating close to the superconductor gap frequency. The mixer chip which comprises the SIS devices, fed by a unilateral finline and matching planar circuits was fabricated on 15 micron silicon substrate using the recently developed Silicon-On-Insulator (SOI) technology. This offered broadband IF and RF performance, with fully integrated on-chip planar circuits resulting in an easily reproducible mixer chip and a simple mixer block. An important consequence of this design is that it can be extended to the supra-THz region and making the fabrication of multi-pixel heterodyne arrays feasible. The extension of the operation of major telescopes such as ALMA, APEX and the GLT from single pixel to large format arrays is the subject of extensive research at present time since it will allow fast mapping combined with high resolution of the submillimetre sky. The technology described in this thesis makes a major contribution to this effort.
Development of Geopolymer from Pond Ash-Thermal Power Plant Waste: Novel Constructional Materials for Civil Engineers
by Muktikanta Panigrahi Ratan Indu Ganguly Radha Raman DashDEVELOPMENT OF GEOPOLYMER FROM POND ASH-THERMAL POWERPLANT WASTE Explains how geopolymer technologies using industrial waste obtained from thermal power plants become cementitious materials in construction sectors for civil engineers. Utilization of waste materials has become a global challenge since they endanger our environment. In this book, the authors demonstrate how to utilize fly ash/pond ash (waste materials from thermal power plants) to produce a novel material called ‘Geopolymer’ (GP). Red mud, slags, etc., are mixed with fly ash to produce GP with enhanced strength. As shown in a few European countries, GP can replace cement, and some permanent structures constructed with GP are now appearing in a few advanced countries. GP, and geopolymer concrete, is considered suitable for the construction of roads, buildings, etc., and will eventually, fully or partially, replace cement. The book highlights the mechanism of the formation of GP from pond ash. Properties of structures made with GP concrete are found to be comparable to those made with cement concrete. Systematic investigations are presented to understand the chemistry of GP formation with pond ash materials. Performances of these materials above ambient temperature, as well as with different environmental conditions, are also evaluated.
