This item is printed on demand - it takes 3-4 days longer - Neuware -Social Learning Systems and Communities of Practice is a collection of classical and contemporary writing associated with learning and systemic change in contexts ranging from cities, to rural development to education to nursing to water management to public policy. It is likely to be of interest to anyone trying to understand how to think systemically and to act and interact effectively in situations experienced as complex, messy and changing. While mainly concerned with professional praxis, where theory and practice inform each other, there is much here that can apply at a personal level.This book offers conceptual tools and suggestions for new ways of being and acting in the world in relation to each other, that arise from both old and new understandings of communities, learning and systems. Starting with twentieth century insights into social learning, learning systems and appreciative systems from Donald Schön and Sir Geoffrey Vickers, the book goes on to consider the contemporary traditions of critical social learning systems and communities of practice, pioneered by Richard Bawden and Etienne Wenger and their colleagues. A synthesis of the ideas raised, written by the editor, concludes this reader. The theory and practice of social learning systems and communities of practice appear to have much to offer in influencing and managing systemic change for a better world. 244 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A recent development in SDC-related problems is the establishment of intelligent SDC models and the intensive use of LMI-based convex optimization methods. Within this theoretical framework, control parameter determination can be designed and stability and robustness of closed-loop systems can be analyzed. This book describes the new framework of SDC system design and provides a comprehensive description of the modelling of controller design tools and their real-time implementation. It starts with a review of current research on SDC and moves on to some basic techniques for modelling and controller design of SDC systems. This is followed by a description of controller design for fixed-control-structure SDC systems, PDF control for general input- and output-represented systems, filtering designs, and fault detection and diagnosis (FDD) for SDC systems. Many new LMI techniques being developed for SDC systems are shown to have independent theoretical significance for robust control and FDD problems. 216 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In his latest book, Dr. Robert A. Norman introduces us to the intriguing concept of preventive dermatology. Although dermatologists have long been patient advocates and have stressed vigorously on the importance of sun avoidance and protection, there is still much more that we can do to prevent disease. Dr. Norman and his skilled coterie of collaborators discuss two distinct types of prevention in dermatology: the prevention of skin diseases and the prevention of s- temic disorders, some with only very indirect connections to the skin. The frst is fairly well known to dermatologists; the second is truly an emerging concept of great importance. Educational efforts to prevent or at least control skin disease may range from the proper use of sunscreens to weight loss in psoriatic patients, the avoidance of trigger factors in rosacea, proper skin care in atopic dermatitis, or adoption of a low-fat diet to decrease the incidence of actinic keratosis and nonmelanoma skin cancer. Another good example is the use of vaccines to protect against diseases such as herpes zoster and genital HPV infection in females. 332 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Complexities of the requirements for accurate radiation dosimetry evaluation in both diagnostic and therapeutic nuclear medicine (including PET) have grown over the past decade. This is due primarily to four factors: Growing consideration of accurate patient-specific treatment planning for radionuclide therapy as a means of improving the therapeutic benefit, development of more realistic anthropomorphic phantoms and their use in estimating radiation transport and dosimetry in patients, Design and use of advanced Monte Carlo algorithms in calculating the above-mentioned radiation transport and dosimetry which require the user to have a thorough understanding of the theoretical principles used in such algorithms, their appropriateness and their limitations, increasing regulatory scrutiny of the radiation dose burden borne by nuclear medicine patients in the clinic and in the development of new radiopharmaceuticals, thus requiring more accurate and robust dosimetry evaluations.An element common to all four factors is the need for precise radiation dosimetry in nuclear medicine, which is fundamental to the therapeutic success of a patient undergoing radionuclide therapy and to the safety of the patients undergoing diagnostic nuclear medicine and PET procedures.As the complexity of internal radiation dosimetry applied to diagnostic and therapeutic nuclear medicine increases, this book will provide the theoretical foundations for: enabling the practising nuclear medicine physicist to understand the dosimetry calculations being used and their limitations, allowing the research nuclear medicine physicist to critically examine the internal radiation dosimetry algorithms available and under development; and providing the developers of Monte Carlo codes for the transport of radiation resulting from internal radioactive sources with the only comprehensive and definitive. 644 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The objects displayed on a table can take multiple forms. In meetings, it is still very often printed paper although its content was originally created on a computer. The content can also be a 'table', but now in the mathematical sense, showing, e. g. , the budget of a project. Then, we have a 'table' on the table. Most often, the computer-generated contents are subject of frequent changes or dynamic in nature. It is a logical consequence to avoid the detour and the inherent media break by transforming the surface of the table into a display able to show media that are active and can be computer-generated and computer-controlled. At the same time, it is desirable to maintain the inherent features and affordances of working with the objects and the contents while sitting or standing around a table. Electronic Meeting Rooms On the basis of these and other elaborate considerations, we started to design in 1992/1993 an electronic meeting room in Darmstadt at GMD-IPSI (later Fraunhofer IPSI). The setup of our custom-built DOLPHIN-System consisted of a 'traditional' large rectangular wooden table with four physically integrated workstation-like computers with at screens. This set-up was complemented by linking a large ver- cal pen-operated interactive display, at that time the rst LiveBoard outside of Xerox PARC (two of which I was able to get to Darmstadt after my stay at Xerox PARC in 1990). 480 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Micromechanisms of Fracture and Fatigue forms the culmination of 20 years of research in the field of fatigue and fracture. It discusses a range of topics and comments on the state of the art for each.The first part is devoted to models of deformation and fracture of perfect crystals. Using various atomistic methods, the theoretical strength of solids under simple and complex loading is calculated for a wide range of elements and compounds, and compared with experimental data. The connection between the onset of local plasticity in nanoindentation tests and the ideal shear strength is analysed using a multi-scale approach. Moreover, the nature of intrinsic brittleness or ductility of perfect crystal lattices is demonstrated by the coupling of atomistic and mesoscopic approaches, and compared with brittle/ductile behaviour of engineering materials.The second part addresses extrinsic sources of fracture toughness of engineering materials, related to their microstructure and microstructurally-induced crack tortuosity. Micromechanisms of ductile fracture are also described, in relation to the fracture strain of materials. Results of multilevel modelling, including statistical aspects of microstructure, are used to explain remarkable phenomena discovered in experiments.In the third part of the book, basic micromechanisms of fatigue cracks propagation under uniaxial and multiaxial loading are discussed on the basis of the unified mesoscopic model of crack tip shielding and closure, taking both microstructure and statistical effects into account. Applications to failure analysis are also outlined, and an attempt is made to distinguish intrinsic and extrinsic sources of materials resistance to fracture.Micromechanisms of Fracture and Fatigue provides scientists, researchers and postgraduate students with not only a deep insight into basic micromechanisms of fracture behaviour of materials, but also a number of engineering applications. 308 pp. Englisch.
