The Role of Prototypes in Design Research: Overview and Cases Studies (SpringerBriefs in Applied Sciences and Technology)
by Silvia D. FerrarisThis book provides a theoretical framework for design researchers interested in developing their research work about and with prototypes. It describes prototypes' multiple definitions and possible functions in the multifaceted landscape of today's design research. Indeed, while the manufacturing and digital evolutions enable and require new types of advanced prototypes, the design evolution as an academic discipline continuously widens its perspectives, fields, and research methods, among which are the prototypes' applications, features, and purposes. The framework originates from an interpretation of these interrelated phenomena and a collection of case studies. Additionally, it defines those criteria that characterize the relation between the research (context, discipline, and general scope) and the prototype (nature and specific aims) and, altogether, it presents an overview of prototypes' roles in design research.
The Role of Psychological Reactance in Human–Computer Interaction (T-Labs Series in Telecommunication Services)
by Patrick EhrenbrinkThis book provides an in-depth investigation on the psychological phenomenon "reactance“ in the context of Human-Computer Interaction (HCI). The author argues that the complexity and autonomy of modern technology can sometimes be overwhelming and can then be perceived as a threat to freedom by its users, thereby diminishing acceptance. The book investigates if and how this is the case and provides strategies to regain the lost acceptance. Topics include relevance of reactance on HCI, triggers for reactance, consequences of reactance, measurement of reactance, and countermeasures to reactance.

The Role of Renewable Energy Technology in Holistic Community Development
by Alexander ZahndThis thesis documents almost twenty years of the author's work on the development and implementation of a new approach to holistic community development in remote and disadvantaged villages in Nepal. It describes the theoretical basis of the work, the main research activities, and the practical outcomes of the implemented programs. One of the fundamental cornerstones of holistic community development is the provision of appropriate and sustainable solutions for the long-term development of local communities. This requires that people's own identified needs be recognized and addressed in partnership with them in holistic ways. The author explains the many synergies that result from this holistic approach to community development. Another cornerstone of his approach is to utilise the communities' locally available renewable resources for long-term sustainable development. One of the key findings of the thesis is that improved access to energy services, such as cooking with a smokeless metal stove in a clean indoor environment, basic indoor lighting, and increased food production and safe food storage (through a greenhouse and a solar drier respectively), need to be at the very heart of any long-term holistic community development project. The thesis demonstrates that tapping into locally available renewable energy resources and converting them, through contextualized and locally manufactured renewable energy technologies, has a central role in long-term holistic community development programs. Such programs are successful because they provide both appropriate technologies and life-changing experiences for the local users involved.
Role of Reservoir Operation in Sustainable Water Supply to Subak Irrigation Schemes in Yeh Ho River Basin: Learning From Experiences of Ancient Subak Schemes For Participatory Irrigation System Management in Bali
by Mawiti Infantri YektiA Subak irrigation scheme, primarily in Bali, Indonesia concerns an irrigation system of which the construction, operation and management are based on agreed principles of technology, management of agriculture and religious community. Subak systems have been well known since the 9th Century. As a manifestation of the Cultural Landscape of Bali Province the Subak schemes are since June, 2012 included in the World Heritage List of UNESCO. These systems are managed by a Subak Association based on the Tri Hita Karana philosophy - harmony between human beings and God, harmony between people and nature, and harmony between people and people. The problem of insufficient water in the dry season developed in the Yeh Ho River Basin. Because of this the main objective of this study was to develop an optimal reservoir operation strategy in relation to the water supply of the Subak irrigation schemes, capable to support agricultural productivity at upstream, midstream and downstream level. Based on a Generic Algorithm the RIBASIM model was applied using the dependable 80% of discharge and shifting the start of land preparation. The results provide evidence that the cropping pattern of the fifth scenario results in an overall optimal agriculture production of the Subak schemes. The recoverable flow considered in the river basin scheme model plays an important role in the optimisation. Nevertheless, if a normal hydro-climate occurs, the other scenarios, especially the first scenario, can be applied as well. This reflects the applicability of the Tri Hita Karana philosophy on harmony among people and harmony among people and nature.

Role of Rhizospheric Microbes in Soil: Volume 2: Nutrient Management And Crop Improvement
by Vijay Singh MeenaIn any ecosystem, plant and microbe interaction is inevitable. They not only co-exist but also support each other’s survival and provide sustenance in stressful environments. Agro-ecosystems in many regions around the globe are affected by high temperatures, soil salinity/alkalinity, low pH and metal toxicity. High salinity and severe draught are other major constraints affecting agricultural practices and also plants in the wild. A major limiting factor affecting global agricultural productivity is environmental stresses. Apart from decreasing yield, they also have a devastating impact on plant growth. Plants battle with various kind of stresses with the help of symbiotic associations with the rhizospheric microbes. Naturally occuring plant-microbe interactions facilitate the survival of plants under these stressful conditions.The rhizosphere consists of several groups of microbes, plant growth-promoting bacteria (PGPB) is one such group of microbes that assists plants in coping with multiple stresses and also promote plant growth. These efficient microbes support the stress physiology of the plants and can be extremely useful in solving agricultural as well food- security problems.This book provides a detailed, holistic description of plant and microbe interaction. It elucidates various mechanisms of nutrient management, stress tolerance and enhanced crop productivity in the rhizosphere, discussing The rhizospheric flora and its importance in enhancement of plant growth, nutrient content, yield of various crops and vegetables as well as soil fertility and health.

Various examples of plant microbe interaction in rhizospheric soil are elaborated to facilitate the development of efficient indigenous microbial consortia to enhance food and nutritional security. Providing a comprehensive information source on microbes and their role in agricultural and soil sustainability, this timely research book is of particular interest to students, academics and researchers working in the fields of microbiology, soil microbiology, biotechnology, agronomy, and the plant protection sciences, as well as for policy makers in the area of food security and sustainable agriculture.
Role of Seismic Testing Facilities in Performance-Based Earthquake Engineering
by Michael N. Fardis Zoran T. RakicevicNowadays research in earthquake engineering is mainly experimental and in large-scale; advanced computations are integrated with large-scale experiments, to complement them and extend their scope, even by coupling two different but simultaneous tests. Earthquake engineering cannot give answers by testing and qualifying few, small typical components or single large prototypes. Besides, the large diversity of Civil Engineering structures does not allow drawing conclusions from only a few tests; structures are large and their seismic response and performance cannot be meaningfully tested in an ordinary lab or in the field. So, seismic testing facilities should be much larger than in other scientific fields; their staff has to be resourceful, devising intelligent ways to carry out simultaneously different tests and advanced computations. To better serve such a mission European testing facilities and researchers in earthquake engineering have shared their resources and activities in the framework of the European project SERIES, combining their research and jointly developing advanced testing and instrumentation techniques that maximize testing capabilities and increase the value of the tests. This volume presents the first outcomes of the SERIES and its contribution towards Performance-based Earthquake Engineering, i.e., to the most important development in Earthquake Engineering of the past three decades. The concept and the methodologies for performance-based earthquake engineering have now matured. However, they are based mainly on analytical/numerical research; large-scale seismic testing has entered the stage recently. The SERIES Workshop in Ohrid (MK) in Sept. 2010 pooled together the largest European seismic testing facilities, Europe's best experts in experimental earthquake engineering and select experts from the USA, to present recent research achievements and to address future developments. Audience: This volume will be of interest to researchers and advanced practitioners in structural earthquake engineering, geotechnical earthquake engineering, engineering seismology, and experimental dynamics, including seismic qualification.

It investigates the link between agriculture and nutrition in order to better understand how agriculture affects human health and dietary patterns. Given the importance of smallholdings, strategies to increase their productivity are essential to improving food and nutrition security, as well as food diversity.
The Role of Technology in Distance Education (Routledge Revivals)
by Tony BatesThis book, first published in 1984, provides a comprehensive review of the range of technology that was being used in distance education. Technological developments in word processing, video-disc and viewdata as well as computer-based learning had revolutionised the potential for distance education. These developments required the role of more ’conventional’ distance learning media, such as broadcasting, tuition and text, to be reassessed. This book, written by international experts in the field, explored the state of the art at the time, and also provided their ideas on how future developments were likely to evolve. This book is ideal for those studying education and communications.
The Role of Technology in Science: Philosophical Perspectives
by Sven Ove HanssonThis edited volume explores the interplay between philosophies in a wide-ranging analysis of how technological applications in science inform our systems of thought. Beginning with a historical background, the volume moves on to explore a host of topics, such as the uses of technology in scientific observations and experiments, the salient relationship between technology and mechanistic notions in science and the ways in which today's vast and increasing computing power helps scientists achieve results that were previously unattainable. Technology allows today's researchers to gather, in a matter of hours, data that would previously have taken weeks or months to assemble. It also acts as a kind of metaphor bank, providing biologists in particular with analogies (the heart as a 'pump', the nervous system as a 'computer network') that have become common linguistic currency. This book also examines the fundamental epistemological distinctions between technology and science and assesses their continued relevance. Given the increasing amalgamation of the philosophies of science and technology, this fresh addition to the literature features pioneering work in a promising new field that will appeal both to philosophers and scientific historiographers.

The Role of Topology in Materials (Springer Series In Solid-state Sciences Ser. #189)
by Sanju Gupta Avadh SaxenaThis book presents the most important advances in the class of topological materials and discusses the topological characterization, modeling and metrology of materials. Further, it addresses currently emerging characterization techniques such as optical and acoustic, vibrational spectroscopy (Brillouin, infrared, Raman), electronic, magnetic, fluorescence correlation imaging, laser lithography, small angle X-ray and neutron scattering and other techniques, including site-selective nanoprobes. The book analyzes the topological aspects to identify and quantify these effects in terms of topology metrics. The topological materials are ubiquitous and range from (i) de novo nanoscale allotropes of carbons in various forms such as nanotubes, nanorings, nanohorns, nanowalls, peapods, graphene, etc. to (ii) metallo-organic frameworks, (iii) helical gold nanotubes, (iv) Möbius conjugated polymers, (v) block co-polymers, (vi) supramolecular assemblies, to (vii) a variety of biological and soft-matter systems, e.g. foams and cellular materials, vesicles of different shapes and genera, biomimetic membranes, and filaments, (viii) topological insulators and topological superconductors, (ix) a variety of Dirac materials including Dirac and Weyl semimetals, as well as (x) knots and network structures. Topological databases and algorithms to model such materials have been also established in this book. In order to understand and properly characterize these important emergent materials, it is necessary to go far beyond the traditional paradigm of microscopic structure–property–function relationships to a paradigm that explicitly incorporates topological aspects from the outset to characterize and/or predict the physical properties and currently untapped functionalities of these advanced materials. Simulation and modeling tools including quantum chemistry, molecular dynamics, 3D visualization and tomography are also indispensable. These concepts have found applications in condensed matter physics, materials science and engineering, physical chemistry and biophysics, and the various topics covered in the book have potential applications in connection with novel synthesis techniques, sensing and catalysis. As such, the book offers a unique resource for graduate students and researchers alike.
The Role of Transit in Emergency Evacuation
by Transportation Research BoardTRB Special Report 294: The Role of Transit in Emergency Evacuation explores the roles that transit systems can play in accommodating the evacuation, egress, and ingress of people from and to critical locations in times of emergency. The report focuses on major incidents that could necessitate a partial to full evacuation of the central business district or other large portion of an urban area. According to the committee that produced the report, transit agencies could play a significant role in an emergency evacuation, particularly in transporting carless and special needs populations, but few urban areas have planned for a major disaster and evacuation that could involve multiple jurisdictions or multiple states in a region, or have focused on the role of transit and other public transportation providers in such an incident. The report offers recommendations for making transit a full partner in emergency evacuation plans and operations, while cautioning emergency managers, elected officials, and the general public to be realistic in their expectations, particularly in a no-notice incident that occurs during a peak service period.

Roll-to-Roll Vacuum Deposition of Barrier Coatings
by Charles A. BishopIt is intended that the book will be a practical guide to provide any reader with the basic information to help them understand what is necessary in order to produce a good barrier coated web or to improve the quality of any existing barrier product.<P><P> After providing an introduction, where the terminology is outlined and some of the science is given (keeping the mathematics to a minimum), including barrier testing methods, the vacuum deposition process will be described. In theory a thin layer of metal or glass-like material should be enough to convert any polymer film into a perfect barrier material. The reality is that all barrier coatings have their performance limited by the defects in the coating. <P>This book looks at the whole process from the source materials through to the post deposition handling of the coated material. This holistic view of the vacuum coating process provides a description of the common sources of defects and includes the possible methods of limiting the defects. This enables readers to decide where their development efforts and money can best be used to improve the barrier performance of their own process or materials. The 2nd edition contains at least 20% new material including additional barrier testing techniques that have been developed and testing and cleaning equipment brought to market since the 1st edition was published in 2010. The topic of adhesion is covered in more detail and there is a section on the Hanson Solubility Parameter which is a method of predicting the solubility of gases or liquids in materials.
Roller-Compacted Concrete Dams (ICOLD Bulletins Series #177)
by Cigb IcoldICOLD Bulletin 177 ‘Roller-Compacted Concrete Dams’ presents the state-of-the-art on roller-compacted concrete technology for dams, incorporating the advances of the RCC technology for dams over the last 15 years since the previous Bulletin on the topic was released in 2003. Hence, the present ICOLD Bulletin 177 supersedes ICOLD Bulletin 126 (‘Roller-compacted concrete dams - State of the art and case histories’, published in 2003) and ICOLD Bulletin 75 (‘Roller-Compacted Concrete for Gravity Dams’ published in 1989). While roller-compacted concrete technology could have still been considered a new technology in 2003, it is now true to say that construction by roller-compaction has become the standard approach for large concrete gravity dams. This Bulletin addresses all aspects of the planning, design, construction and performance of RCC in dams. Mixture proportioning and quality control are discussed and a comprehensive listing of references is included. Many aspects of RCC in dams have become better understood since the publication of Bulletin No 126 and the present Bulletin contains less information on the particular approaches applied in different countries, but includes more comprehensive information particularly in relation to design, mixture proportioning and construction. With greater understanding, it has further been possible to highlight more definitively the requirements of successful RCC dams, as well as the pitfalls and difficulties that can be associated with RCC dam design and construction. Le Bulletin CIGB 177, intitulé « Barrages en Béton Compacté au Rouleau » présente les dernières avancées en matière de technologie du béton compacté au rouleau pour les barrages intégrant les progrès de la technologie BCR pour les barrages au cours des 15 dernières années, depuis que le dernier bulletin sur le sujet a été publié en 2003. Par conséquent, le bulletin 177 remplace le bulletin 126 (« Barrages en béton compacté au rouleau - Technique actuelle et exemples », publié en 2003) et le bulletin 75 (« Béton compacté au rouleau pour barrages-poids - Technique actuelle » publié en 1989). Alors que la technologie du BCR pourrait encore être considérée comme une nouvelle technologie en 2003, il est maintenant vrai de dire que la construction par le compactage par rouleaux est devenue l'approche standard pour les grands barrage-poids en béton. Ce bulletin aborde tous les aspects de la planification, de la conception, de la construction et de la performance du BCR dans les barrages. Le dosage du mélange et le contrôle de la qualité sont discutés et une liste exhaustive des références est incluse. De nombreux aspects du BCR dans les barrages sont mieux compris depuis la publication du Bulletin no 126. Le présent bulletin contient moins d'informations sur les approches particulières appliquées dans différents pays, mais comprend des informations plus complètes notamment en ce qui concerne la conception, le dosage du mélange et la construction. Avec une plus grande compréhension, il a été possible de mettre en évidence les exigences des barrages en BCR réussis, ainsi que les pièges et les difficultés qui peuvent être associés à la conception et la construction du barrage en BCR.
Rolling Contact Fatigue in a Vacuum
by Michael Danyluk Anoop DhingraThis book deals with wear and performance testing of thin solid film lubrication and hard coatings in an ultra-high vacuum (UHV), a process which enables rapid accumulation of stress cycles compared with testing in oil at atmospheric pressure. The authors' lucid and authoritative narrative broadens readers' understanding of the benefits of UHV testing: a cleaner, shorter test is achieved in high vacuum, disturbance rejection by the deposition controller may be optimized for maximum fatigue life of the coating using rolling contact fatigue testing (RCF) in a high vacuum, and RCF testing in UHV conditions enables a faster study of deposition control parameters. In short, Rolling Contact Fatigue in a Vacuum is an indispensable resource for researchers and engineers concerned with thin film deposition, solar flat panel manufacturing, physical vapor deposition, MEMS manufacturing (for lubrication of MEMS), tribology in a range of industries, and automotive and marine wear coatings for engines and transmissions.
Rolling of Advanced High Strength Steels: Theory, Simulation and Practice
by Jingwei Zhao Zhengyi JiangAdvanced high strength steels (AHSSs) for auto-making are primarily produced by rolling, plus heat treatment technologies if necessary. However, due to the metallurgical complexity of AHSSs, it is impossible to roll all of the AHSS grades in a rolling mill with the same rolling technology. Each of AHSSs has unique applications in vehicles, and specified rolling technologies are required to produce high quality AHSS products where they might be the best employed to meet performance demands of the automotive parts. Such background has prompted the publication of this scholarly book in the area of rolling of AHSSs with a purpose of providing readers with a valuable technical document that can be used in the research and development of AHSSs for automotive and other manufacturing industries. With contributors from USA, Germany, Poland, Italy, Spain, Austria, Australia, China, India and Iran, the book highlights the latest advances in rolling technologies of AHSSs. It focuses on the theory, simulation and practice of the rolling of AHSSs: The book introduces the history, types and advances of AHSSs and their processes; proposes new theory that is applicable to the rolling of AHSSs, presents mathematical and numerical modelling of AHSSs in rolling; covers thermomechanical processing technologies of AHSSs; provides case studies on the rolling practice of the most popular AHSSs and includes other rolling-related technologies of AHSSs. The book will be useful for both theoretical and applied research aimed at AHSSs rolling technologies, and will be a scientific and valuable literature for the metallurgists, engineers, materials scientists, academics and graduate students who are studying and working with AHSSs and their rolling technologies worldwide.
