Libros sobre el tema "CAD data exchange"

Transformations of Identity and Society in Anglo-Saxon Essex: A Case Study of an Early Medieval North Atlantic Community presents the results of a comprehensive archaeological study of early medieval Essex (c.AD 400-1066). This region provides an important case study for examining coastal societies of north-western Europe. Drawing on a wealth of new data, the author demonstrates the profound influence of maritime contacts on changing expressions of cultural affiliation. It is argued that this Continental orientation reflects Essex’s longterm engagement with the emergent, dynamic North Sea network. The wide chronological focus and inclusive dataset enables long-term socio-economic continuity and transformation to be revealed. These include major new insights into the construction of group identity in Essex between the 5th and 11th centuries and the identification of several previously unknown sites of exchange. The presentation also includes the first full archaeological study of Essex under ‘Viking’ rule.

Nun findet schon die 6. Fachtagung Verzahnungsmesstechnik statt. Diese Tagung beschäftigt sich wieder mit Fragen rund um die Verzahnungsmesstechnik. Die Schwerpunkte der Tagung spiegeln die Anforderungen an diese Messtechnik wider. So stellt die Digitalisierung unter dem Schlagwort „Industrie 4.0“ Anforderungen an die Software, Datenübertragung und natürlich an die Messtechniker. Ein Schwerpunkt ist deshalb wieder das „Gear Data Exchange Format“ (GDE). Anhand von Live-Demonstrationen zur Übertragung von Verzahnungsdaten in das CAD und in die Messmaschine wird der Nutzen dieses Formats in einem umfangreichen Gemeinschaftsvortrag dargestellt. Bisher spielte die taktile Messtechnik die Hauptrolle in der Einzelformprüfung von Zahnrädern. Heute werden wir immer wieder mit optischen Sensoren konfrontiert, deren Performance in der Verzahnungsmesstechnik noch nicht ausreichend erschlossen ist. Deshalb widmet sich eine ganze Session diesem Thema. Hier erwarte ich interessante Auss...

Exchange rate volatility is said to exemplify the economic health of a country. Exchange rate break points (known as structural breaks) have a momentous impact on the macroeconomy of a country. Nonetheless, this country study makes use of both unsupervised and supervised machine learning algorithms to classify structural changes as regime shifts in real exchange rates in South Africa. Weekly data for the period January 2003–June 2020 are used. To these data we apply both non-linear principal component analysis and Markov-switching generalized autoregressive conditional heteroscedasticity. The former approach is used to reduce the dimensionality of the data using an orthogonal linear transformation by preserving the statistical variance of the data, with the proviso that a new trait is non-linearly independent, and it identifies the number of regime switches that are to be used in the Markov-switching model. The latter is used to partition the variance in each regime by allowing an estimation of multiple break transitions. The transition breakpoints estimates derived from this machine learning approach produce results that are comparable to other methods on similar system sizes. Application of these methods shows that the machine learning approach can also be employed to identify structural changes as a regime-switching process. During times of financial crisis, the growing concern over exchange rate volatility, including its adverse effects on employment and growth, broadens the debates on exchange rate policies. Our results should help the South African monetary policy committee to anticipate when exchange rates will pick up and be prepared for the effects of periods of high exchange rates.

As we look to the evolving health care industry with improved care quality, health outcomes, and cost parameters, the demands of the critical care environment require a transformation. Technology, process, and people are at the centre of this transformation. The power is in the knowledge that can be achieved and the process improvements that can be made through automation. Five major areas of technology evolution include workflow automation, information exchange, clinical decision support, and predictive modelling, remote monitoring, and data analytics. If designed properly, technology can result in doing things differently (better) and doing different things. Information exchange is required for quality and efficient critical care information delivery. Data analytics will use information for comparative effectiveness, registry reporting, population management, and research study recruiting.

Big data promises to harness the power of advanced computing to transform health and health care, including cancer research and care delivery. In health care, big data can be generated by administrative and clinical processes, by patients and families, and by machines. Ultimately, the goal of big data is to transform data into actionable knowledge with attention to four dimensions: person-level data collection; data access, exchange, and aggregation; population-level analytics; and provider, researcher, or patient-facing clinical decision support. A fabric of trust forms the basis for policies for governance, privacy and security, and confidentiality. This chapter offers several examples of the application of big data along the cancer care continuum, ranging from primary prevention through diagnosis, survivorship, and end-of-life care. Challenges to the effective collection and use of big data include its integration with health care delivery; interoperability; and the need for validated, well-designed informatics tools.

The goal of mechanical ventilation is to achieve adequate gas exchange while minimizing haemodynamic compromise and ventilator-associated lung injury. Volume-controlled ventilation can be delivered via several modes, including controlled mechanical ventilation, assist control (AC) and synchronized intermittent mandatory ventilation (SIMV). .In volume-controlled modes, the clinician sets the flow pattern, flow rate, trigger sensitivity, tidal volume, respiratory rate, positive end-expiratory pressure, and fraction of inspired oxygen. Patient ventilator synchrony can be enhanced by setting appropriate trigger sensitivity and inspiratory flow rate. I:E ratio can be adjusted to improve oxygenation, avoid air trapping and enhance patient comfort. There is little data regarding the benefits of one volume-controlled mode over another. In acute respiratory distress syndrome, low tidal volume ventilation in conjunction with plateau pressure limitation should be employed as there is a reduction in mortality with this strategy. This chapter addresses respiratory mechanics, modes and settings, clinical applications, and limitations of volume-controlled ventilation.

Technological evolution and revolution are both driven by the discovery of new functionalities, new materials and the design of yet smaller, faster, and more energy-efficient components. Progress is being made at a breathtaking pace, stimulated by the rapidly growing demand for more powerful and readily available information technology. High-speed internet and data-streaming, home automation, tablets and smartphones are now ‘necessities’ for our everyday lives. Consumer expectations for progressively more data storage and exchange appear to be insatiable. In this context, ferroic domain walls have attracted recent attention as a completely new type of oxide interface. In addition to their functional properties, such walls are spatially mobile and can be created, moved, and erased on demand. This unique degree of flexibility enables domain walls to take an active role in future devices and hold a great potential as multifunctional 2D systems for nanoelectronics. With domain walls as reconfigurable electronic 2D components, a new generation of adaptive nano-technology and flexible circuitry becomes possible, that can be altered and upgraded throughout the lifetime of the device. Thus, what started out as fundamental research, at the limit of accessibility, is finally maturing into a promising concept for next-generation technology.

The index includes a desiderata table that can be used when ordering seeds.

The purpose of this book is to provide a theoretical foundation and an understanding of atomistic spin-dynamics, and to give examples of where the atomistic Landau-Lifshitz-Gilbert equation can and should be used. The contents involve a description of density functional theory both from a fundamental viewpoint as well as a practical one, with several examples of how this theory can be used for the evaluation of ground state properties like spin and orbital moments, magnetic form-factors, magnetic anisotropy, Heisenberg exchange parameters, and the Gilbert damping parameter. This book also outlines how interatomic exchange interactions are relevant for the effective field used in the temporal evolution of atomistic spins. The equation of motion for atomistic spin-dynamics is derived starting from the quantum mechanical equation of motion of the spin-operator. It is shown that this lead to the atomistic Landau-Lifshitz-Gilbert equation, provided a Born-Oppenheimer-like approximation is made, where the motion of atomic spins is considered slower than that of the electrons. It is also described how finite temperature effects may enter the theory of atomistic spin-dynamics, via Langevin dynamics. Details of the practical implementation of the resulting stochastic differential equation are provided, and several examples illustrating the accuracy and importance of this method are given. Examples are given of how atomistic spin-dynamics reproduce experimental data of magnon dispersion of bulk and thin-film systems, the damping parameter, the formation of skyrmionic states, all-thermal switching motion, and ultrafast magnetization measurements.

As E. P. Thompson so clearly put it, all research is a dialogue between theory and evidence. This implies at least two essential requirements for effective research. The first is to make assumptions explicit so that the accumulation of evidence can be assessed in light of these assumptions. The second is to understand that all research is a process open to development through critical exchange and through disciplining by evidence. This book primarily addresses the second requirement. It focuses on the development of methods through the experiences of multiple dialogues among team members. This chapter explores the first of these requirements, explaining why explicit theory is necessary and how feminist political economy perspectives guided the organization of the team, the identification of research questions, the methodology, data sharing, and the analysis. In doing so, the chapter describes the rapid, site-switching method that evolved during the seven years of the project.

Communication technologies, including the Internet, social media, and countless online applications, create the infrastructure and interface through which many of our interactions take place today. This form of networked communication creates new questions about how we establish relationships, engage in public, build a sense of identity, and delimit the private domain. Digital technologies have also enabled new ways of observing the world; many of our daily interactions leave a digital trail that, if followed, can help us unravel the rhythms of social life and the complexity of the world we inhabit, including dynamics of change. The analysis of digital data requires partnerships across disciplinary boundaries that–although on the rise–are still uncommon. Social scientists, computer scientists, network scientists, and others have never been closer to their goal of trying to understand communication dynamics, but there are not many venues in which they can engage in an open exchange of methods and theoretical insights. This book opens that space and creates a platform to integrate the knowledge produced in different academic silos so that we can address the big puzzles that beat at the heart of social life in this networked age.

This article discusses the current status of archaeological obsidian studies, including techniques used in characterization and sourcing studies, obsidian hydration, and regional syntheses. It begins with an overview of obsidian and the unique formation processes that create it before turning to a discussion of the significance of characterization and sourcing techniques for understanding prehistoric obsidian trade and exchange. It then considers the problematic aspects of the term “sourcing,” despite its ubiquitous use in archaeology and archaeometry, along with the use of X-ray fluorescence in the chemical characterization of obsidian. It also explores obsidian hydration dating methods and equations, factors that can affect the date assignments for hydration specimens, and the various uses of obsidian in prehistoric times. Finally, it addresses some important questions relating to obsidian research and suggests new directions in the field.

A Practical Guide to the Interpretation of Cardiopulmonary Exercise Tests is a short, but comprehensive, guide for those who are involved in the supervision of exercise tests and interpretation of cardiopulmonary exercise test (CPET) data. It is a clear and concise guide which will also be of interest to those who request CPETs and who wish to understand more about how to use the results. The first four chapters cover the reasons why a CPET may be requested, pre-test assessment, supervision of the test to ensure that it is safe, and the practicalities of the test itself. Subsequent chapters look in detail at the key CPET measurements of heart rate, ventilation, oxygen uptake, and carbon dioxide output. There are chapters on the parameters that can be derived from these basic measurements: ventilatory equivalents, oxygen pulse, and the respiratory exchange ratio. Further chapters show how the anaerobic threshold and respiratory compensation point are obtained, and how they can be used to interpret the physiological response to exercise. The role of monitoring oxygen saturation and flow–volume loops during the test is described. The third section of the book has chapters on presentation of results, interpretative strategies, and summaries of classical CPET patterns seen in different diseases. The final chapters consider the role of preoperative CPET testing and how to prescribe exercise. All chapters have pointers to further resources.

The Internet of Things (IoT) is the notion that nearly everything we use, from gym shorts to streetlights, will soon be connected to the Internet; the Internet of Everything (IoE) encompasses not just objects, but the social connections, data, and processes that the IoT makes possible. Industry and financial analysts have predicted that the number of Internet-enabled devices will increase from 11 billion to upwards of 75 billion by 2020. Regardless of the number, the end result looks to be a mind-boggling explosion in Internet connected stuff. Yet, there has been relatively little attention paid to how we should go about regulating smart devices, and still less about how cybersecurity should be enhanced. Similarly, now that everything from refrigerators to stock exchanges can be connected to a ubiquitous Internet, how can we better safeguard privacy across networks and borders? Will security scale along with this increasingly crowded field? Or, will a combination of perverse incentives, increasing complexity, and new problems derail progress and exacerbate cyber insecurity? For all the press that such questions have received, the Internet of Everything remains a topic little understood or appreciated by the public. This volume demystifies our increasingly “smart” world, and unpacks many of the outstanding security, privacy, ethical, and policy challenges and opportunities represented by the IoE. Scott J. Shackelford provides real-world examples and straightforward discussion about how the IoE is impacting our lives, companies, and nations, and explain how it is increasingly shaping the international community in the twenty-first century. Are there any downsides of your phone being able to unlock your front door, start your car, and control your thermostat? Is your smart speaker always listening? How are other countries dealing with these issues? This book answers these questions, and more, along with offering practical guidance for how you can join the effort to help build an Internet of Everything that is as secure, private, efficient, and fun as possible.

Digital platforms are becoming increasingly relevant for the constitution of markets. As they can be used in a multifunctional way, platforms are also having a massive impact on the provision and dissemination of both public and private information. Moreover, they are playing a significant role in social exchange. Platforms that facilitate the provision and dissemination of media content and journalistic work are having both economic and cultural effects on the traditional media and communications industry, which is becoming irrelevant and losing income from advertising and users. Social media platforms, such as Facebook, especially are becoming important means for certain social groups to acquire up-to-date information. Platforms and their growth and development are influencing both the traditional media and journalism, which is becoming clear from the growing financial crisis these two sectors are experiencing. The unfolding transformation process is having diverse effects on both the public sphere and on information and communication processes, which in turn is affecting liberal democracy. These changes require specific attention in both interdisciplinary research and politics (the design of a media and communications landscape, regulation, etc.).

In this book we analyse the sustainability question in the Modern Production System, which today encompasses most of the world economy. We present concepts, theories, indicators, indices, formulas, methods and historical date to examine the evolution and trends of two sustainable development dimensions: socioeconomic and environmental. We focus on the nature-economy nexus and analyse its contradictory process: the more the economics needs nature, the more its cause natural resources depletion and environmental degradation. The huge increase on CO2 emissions in the last three decades – from oil, coal and another non-renewable resources– provides strong evidence to such contradiction. We then analyze the role of material recycle as a solution against both, resources depletion and environmental degradation. Our analysis suggests that the recycle of materials can only contribute to reduce the problem. Moreover, there cycle process of materials depends, on many cases, of public or social subsidies – as financial incentives from the government and domestic material selection. The environment problem transcends borders (as an enterprise, a village, a city, or a country): one can be sustainable, but in fact transfer to other its environmental problem. We adopt the notion of Environmental Space to deal with the sustainability question. We then present and apply the concept of Eco-inequal Exchange to analyse such a question. The environmental movement, which started about fifty years ago, did transform the sustainable development into a global mission. By exposing socio-environmental problems generated by the modern production system itself, this book aims to contribute to a better understanding the limits and possibilities of ours actions as environmentalists.

This book brings together the latest concepts and models in real-estate derivatives, the new frontier in financial markets. The importance of real-estate derivatives in managing property price risk that has destabilized economies frequently in the last hundred years has been brought into the limelight by Robert Shiller over the last three decades. In spite of his masterful campaign for the introduction of real-estate derivatives, these financial instruments are still in a state of infancy. This book aims to provide a state-of-the-art overview of real-estate derivatives at this moment in time, covering the description of these financial products, their applications, and the most important models proposed in the literature in this area. In order to facilitate a better understanding of the situations when these products can be successfully used, ancillary topics such as real-estate indices, mortgages, securitization, and equity release mortgages are also discussed. The book is designed to pay attention to the econometric aspects of realestate index prices, time series, and also to financial engineering no-arbitrage principles governing pricing of derivatives. The emphasis is on understanding the financial instruments through their mechanics and comparative description. The examples are based on real-world data from exchanges or frommajor investment banks or financial houses in London. The numerical analysis is easily replicable with Excel and Matlab. This is the most advanced published book in this area, combining practical relevance with intellectual rigour. Real-estate derivatives will become important for managing macro risks in order to pass stress tests imposed by regulators.

These Guidelines are one of the results of the four-year research project “Open Online Learning for Digital and Networked Society” (2017-2021). The project objective was to enable university teachers to design open and online learning through open and online learning curriculum and environment applying learning analytics as a metacognitive tool and creating open and online learning assessment and recognition practices, responding to the needs of digital and networked society. The research of the project resulted in 10 scientific publications and 2 studies prepared by Vytautas Magnus university Institute of Innovative Studies research team in collaboration with their international research partners from Germany, Spain and Portugal. The final stage of the research attempted creating open and online learning assessment and recognition practices, responding to the learner needs in contemporary digital and networked society. The need for open learning recognition has been increasing during the recent decade while the developments of open learning related to the Covid 19 pandemics have dramatically increased the need for systematic and high-quality assessment and recognition of learning acquired online. The given time also relates to the increased need to offer micro-credentials to learners, as well as a rising need for universities to prepare for micro-credentialization and issue new digital credentials to learners who are regular students, as well as adult learners joining for single courses. The increased need of all labour - market participants for frequent and fast renewal of competences requires a well working and easy to use system of open learning assessment and recognition. For learners, it is critical that the micro-credentials are well linked to national and European qualification frameworks, as well as European digital credential infrastructures (e.g., Europass and similar). For employers, it is important to receive requested quality information that is encrypted in the metadata of the credential. While for universities, there is the need to properly prepare institutional digital infrastructure, organizational procedures, descriptions of open learning opportunities and virtual learning environments to share, import and export the meta-data easily and seamlessly through European Digital Hub service infrastructures, as well as ensure that academic and administrative staff has digital competencies to design, issue and recognise open learning through digital and micro-credentials. The first chapter of the Guidelines provides a background view of the European Qualification Framework and National Qualification frameworks for the further system of gaining, stacking and modelling further qualifications through open online learning. The second chapter suggests the review of current European policy papers and consultations on the establishment of micro-credentials in European higher education. The findings of the report of micro-credentials higher education consultation group “European Approach to Micro-credentials” is shortly introduced, as well as important policy discussions taking place. Responding to the Rome Bologna Comunique 2020, where the ministers responsible for higher education agreed to support lifelong learning through issuing micro-credentials, a joint endeavour of DG Employment, Social Affairs and Inclusion and DG Research and Innovation resulted in one of the most important political documents highlighting the potential of micro-credentials towards economic, social and education innovations. The consultation group of experts from the Member States defined the approach to micro-credentials to facilitate their validation, recognition and portability, as well as to foster a larger uptake to support individual learning in any subject area and at any stage of life or career. The Consultation Group also suggested further urgent topics to be discussed, including the storage, data exchange, portability, and data standards of micro-credentials and proposed EU Standard of constitutive elements of micro-credentials. The third chapter is devoted to the institutional readiness to issue and to recognize digital and micro-credentials. Universities need strategic decisions and procedures ready to be enacted for assessment of open learning and issuing micro-credentials. The administrative and academic staff needs to be aware and confident to follow these procedures while keeping the quality assurance procedures in place, as well. The process needs to include increasing teacher awareness in the processes of open learning assessment and the role of micro-credentials for the competitiveness of lifelong learners in general. When the strategic documents and procedures to assess open learning are in place and the staff is ready and well aware of the processes, the description of the courses and the virtual learning environment needs to be prepared to provide the necessary metadata for the assessment of open learning and issuing of micro-credentials. Different innovation-driven projects offer solutions: OEPass developed a pilot Learning Passport, based on European Diploma Supplement, MicroHE developed a portal Credentify for displaying, verifying and sharing micro-credential data. Credentify platform is using Blockchain technology and is developed to comply with European Qualifications Framework. Institutions, willing to join Credentify platform, should make strategic discussions to apply micro-credential metadata standards. The ECCOE project building on outcomes of OEPass and MicroHE offers an all-encompassing set of quality descriptors for credentials and the descriptions of learning opportunities in higher education. The third chapter also describes the requirements for university structures to interact with the Europass digital credentials infrastructure. In 2020, European Commission launched a new Europass platform with Digital Credential Infrastructure in place. Higher education institutions issuing micro-credentials linked to Europass digital credentials infrastructure may offer added value for the learners and can increase reliability and fraud-resistant information for the employers. However, before using Europass Digital Credentials, universities should fulfil the necessary preconditions that include obtaining a qualified electronic seal, installing additional software and preparing the necessary data templates. Moreover, the virtual learning environment needs to be prepared to export learning outcomes to a digital credential, maintaining and securing learner authentication. Open learning opportunity descriptions also need to be adjusted to transfer and match information for the credential meta-data. The Fourth chapter illustrates how digital badges as a type of micro-credentials in open online learning assessment may be used in higher education to create added value for the learners and employers. An adequately provided metadata allows using digital badges as a valuable tool for recognition in all learning settings, including formal, non-formal and informal.
