Visibility Algorithms in the Plane by Subir Kumar Ghosh Pdf

A human observer can effortlessly identify visible portions of geometric objects present in the environment. However, computations of visible portions of objects from a viewpoint involving thousands of objects is a time consuming task even for high speed computers. To solve such visibility problems, efficient algorithms have been designed. This book presents some of these visibility algorithms in two dimensions. Specifically, basic algorithms for point visibility, weak visibility, shortest paths, visibility graphs, link paths and visibility queries are all discussed. Several geometric properties are also established through lemmas and theorems. With over 300 figures and hundreds of exercises, this book is ideal for graduate students and researchers in the field of computational geometry. It will also be useful as a reference for researchers working in algorithms, robotics, computer graphics and geometric graph theory, and some algorithms from the book can be used in a first course in computational geometry.

Complex Engineering Service Systems by Irene Ng,Glenn Parry,Peter Wild,Duncan McFarlane,Paul Tasker Pdf

For manufacturers of complex engineering equipment, the focus on service and achieving outcomes for customers is the key to growth. Yet, the capability to provide service for complex engineered products is less understood. Taking a trans-disciplinary approach, Complex Engineering Service Systems covers various aspects of service in complex engineering systems, with perspectives from engineering, management, design, operations research, strategy, marketing and operations management that are relevant to different disciplines, organisation functions, and geographic locations. The focus is on the many facets of complex engineering service systems around a core integrative framework of three value transformations – that of material/equipment, information and people. Complex Engineering Service Systems is the outcome of the EPSRC/BAE Systems S4T (Service Support Solutions: Strategy and Transition) research programme of 10 universities and 27 researchers, which examined how high-value manufacturers of complex engineering products adapt to a multi-partnered environment to design and deliver value in a service system. Complex Engineering Service Systems aims to be the main source of knowledge for academics and professionals in the research and practice of contracting, managing, designing, leading, and delivering complex engineering service systems. The book takes a value-based approach to integrating equipment and human factors into a total service provision. In doing so, it aims to advance the field of service systems and engineering.

Syntactic And Structural Pattern Recognition - Theory And Applications by Horst Bunke,Alberto Sanfeliu Pdf

This book is currently the only one on this subject containing both introductory material and advanced recent research results. It presents, at one end, fundamental concepts and notations developed in syntactic and structural pattern recognition and at the other, reports on the current state of the art with respect to both methodology and applications. In particular, it includes artificial intelligence related techniques, which are likely to become very important in future pattern recognition.The book consists of individual chapters written by different authors. The chapters are grouped into broader subject areas like “Syntactic Representation and Parsing”, “Structural Representation and Matching”, “Learning”, etc. Each chapter is a self-contained presentation of one particular topic. In order to keep the original flavor of each contribution, no efforts were undertaken to unify the different chapters with respect to notation. Naturally, the self-containedness of the individual chapters results in some redundancy. However, we believe that this handicap is compensated by the fact that each contribution can be read individually without prior study of the preceding chapters. A unification of the spectrum of material covered by the individual chapters is provided by the subject and author index included at the end of the book.

Complex Artificial Environments by Juval Portugali Pdf

Juval Portugali The notion of complex artificial environments (CAE) refers to theories of c- plexity and self-organization, as well as to artifacts in general, and to artificial - vironments, such as cities, in particular. The link between the two, however, is not trivial. For one thing, the theories of complexity and self-organization originated in the “hard” science and by reference to natural phenomena in physics and bi- ogy. The study of artifacts, per contra, has traditionally been the business of the “soft” disciplines in the humanities and social sciences. The notion of “complex artificial environments” thus implies the supposition that the theories of compl- ity and self-organization, together with the mathematical formalisms and meth- ologies developed for their study, apply beyond the domain of nature. Such a s- st position raises a whole set of questions relating to the nature of 21 century cities and urbanism, to philosophical issues regarding the natural versus the artificial, to the methodological legitimacy of interdisciplinary transfer of theories and me- odologies and to the implications that entail the use of sophisticated, state-of-t- art artifacts such as virtual reality (VR) cities and environments. The three-day workshop on the study of complex artificial environments that took place on the island of San Servolo, Venice, during April 1-3, 2004, was a gathering of scholars engaged in the study of the various aspects of CAE.

Managing Complex Projects by Kathleen B. Hass PMP Pdf

For organizations to thrive, indeed to survive, in today's global economy, we must find ways to dramatically improve the performance of large-scale projects. Applying the concepts of complexity theory can complement conventional project management approaches and enable us to adapt to the unrelenting change that we ignore at our own peril. Managing Complex Projects: A New Model offers an innovative way of looking at projects and treating them as complex adaptive systems. Applying the principles of complexity thinking will enable project managers and leadership teams to manage large-scale initiatives successfully. • Explore how complexity thinking can be used to find new, creative ways to think about and manage projects • Diagnose complexity on a wide range of projects — from small, independent, short projects to highly complex, longer projects • Understand and manage the complexity of the business problem, opportunity, solution, and other dimensions that come into play when managing large-scale efforts Use the Project Complexity Model to determine the most effective approach to managing all aspects of a project based on the level of complexity involved.

Evaluative Perception by Anna Bergqvist,Robert Cowan Pdf

Evaluation is ubiquitous. Indeed, it isn't an exaggeration to say that we assess actions, character, events, and objects as good, cruel, beautiful, etc., almost every day of our lives. Although evaluative judgement - for instance, judging that an institution is unjust - is usually regarded as the paradigm of evaluation, it has been thought by some philosophers that a distinctive and significant kind of evaluation is perceptual. For example, in aesthetics, some have claimed that adequate aesthetic judgement must be grounded in the appreciator's first hand-hand perceptual experience of the item judged. In ethics, reference to the existence and importance of something like ethical perception is found in a number of traditions, for example, in virtue ethics and sentimentalism. This volume brings together philosophers working in aesthetics, epistemology, ethics, philosophy of mind, and value theory to investigate what we call 'evaluative perception'. Specifically, they engage with (1) Questions regarding the existence and nature of evaluative perception: Are there perceptual experiences of values? If so, what is their nature? Are perceptual experiences of values sui generis? Are values necessary for certain kinds of perceptual experience? (2) Questions about epistemology: Can evaluative perceptual experiences ever justify evaluative judgements? Are perceptual experiences of values necessary for certain kinds of justified evaluative judgements? (3) Questions about value theory: Is the existence of evaluative perceptual experience supported or undermined by particular views in value theory? Are particular views in value theory supported or undermined by the existence of evaluative perceptual experience?

Managing Complex Models for Computer Graphics by Jonathan Mark Sewell Pdf

Abstract: "Three-dimensional computer graphics is [sic] becoming more common as increasing computational power becomes readily available. Although the images that can be produced are becoming more complex, users' expectations continue to grow. This dissertation examines the changes in computer graphics software that will be needed to support continuing growth in complexity, and proposes techniques for tackling the problems that emerge. Increasingly complex models will involve longer rendering times, higher memory requirements, longer data transfer periods and larger storage capacities. Furthermore, even greater demands will be placed on the constructors of such models. This dissertation aims to describe how to construct scalable systems which can be used to visualise models of any size without requiring dedicated hardware. This is achieved by controlling the quality of the results, and hence the costs incurred. In addition, the use of quality controls can become a tool to help users handle the large volume of information arising from complex models. The underlying approach is to separate the model from the graphics application which uses it, so that the model exists independently. By doing this, an application is free to access only the data which is required at any given time. For the application to function in this manner, the data must be in an appropriate form. To achieve this, approximation hierarchies are defined as a suitable new model structure. These utilise multiple representations of both objects and groups of objects at all levels in the model. In order to support such a structure, a novel method is proposed for rapidly constructing simplified representations for groups of complex objects. By calculating a few geometrical attributes, it is possible to generate replacement objects that preserve important aspects of the originals. Such objects, once placed into an approximation hierarchy, allow rapid loading and rendering of large portions of a model. Extensions to rendering algorithms are described that take advantage of this structure. The use of multiple representations encompasses not only different quality levels, but also different storage formats and types of objects. It provides a framework within which such aspects are hidden from the user, facilitating the sharing and re-use of objects. A model manager is proposed as a means of encapsulating these mechanisms. This software gives, as far as possible, the illusion of direct access to the whole complex model, while at the same time making the best use of the limited resources available."

From Truth and truth by Francis Etheredge Pdf

What emerges in this second book of the trilogy is that the very “ground” and content of experience is richer than what can be reduced to a particular account of it. As such, dialogue develops from the “natural” diversity of what is “of” faith and what is “of” reason. Neither faith nor reason, however, originates “from” experience; rather, both are “witnessed” in experience. In other words, taking up questions about the nature of man, whether philosophically, psychologically or in terms of social structures, manifests both a variety of points of departure and, at the same time, the manifold conversations that are possible in the “field of culture”.Focusing particularly on the work of St. John Paul II, the first essay examines the answer of reason and the answer of faith to the same question: What is man? Conversion, too, entails an “unexpected” relationship to natural truth, which, in its own way, is both adequate and inadequate to salvation. Communication, as it were, runs throughout these essays; however, in particular, there is a need to enrich our human understanding of the process of “coming to ourselves” with the insights of spiritual discernment. Axiomatically, however, it is possible to say that just as we come to exist through a relationship to others, so our healing and holiness are manifest through our relationship to others in the “Other”. Furthermore, while it is ultimately true that we exist as individually rooted in the social structure of our origin and the times in which we live, we need to critically participate in the dialogue which identifies our common “reality” and not live our lives covered in “psycho-social” labels of one kind or another.As a whole, then, there is an incomparable range and depth to “dialogue”. Indeed, given the many critical situations in the world, it is increasingly indispensable and essential that humanity choose the incredible wealth of dialogue in contrast to the possibility of a “polarised” and “conflictual” structure between people and peoples.

Developing Assessment-Capable Visible Learners, Grades K-12 by Nancy Frey,John Hattie,Douglas Fisher Pdf

“When students know how to learn, they are able to become their own teachers.” —Nancy Frey, Douglas Fisher, and John Hattie Imagine students who describe their learning in these terms: “I know where I’m going, I have the tools I need for the journey, and I monitor my own progress.” Now imagine the extraordinary difference this type of ownership makes in their progress over the course of a school year. This illuminating book shows how to make this scenario an everyday reality. With its foundation in principles introduced in the authors’ bestselling Visible Learning for Literacy, this resource delves more deeply into the critical component of self-assessment, revealing the most effective types of assessment and how each can motivate students to higher levels of achievement.
