Buch. Zustand: Neu. Neuware - The increasing amount of information available in today's world raises the need to retrieve relevant data efficiently. Unlike text-based retrieval, where keywords are successfully used to index into documents, content-based image retrieval poses up front the fundamental questions how to extract useful image features and how to use them for intuitive retrieval. We present a novel approach to the problem of navigating through a collection of images for the purpose of image retrieval, which leads to a new paradigm for image database search. We summarize the appearance of images by distributions of color or texture features, and we define a metric between any two such distributions. This metric, which we call the 'Earth Mover's Distance' (EMD), represents the least amount of work that is needed to rearrange the mass is one distribution in order to obtain the other. We show that the EMD matches perceptual dissimilarity better than other dissimilarity measures, and argue that it has many desirable properties for image retrieval. Using this metric, we employ Multi-Dimensional Scaling techniques to embed a group of images as points in a two- or three-dimensional Euclidean space so that their distances reflect image dissimilarities as well as possible. Such geometric embeddings exhibit the structure in the image set at hand, allowing the user to understand better the result of a database query and to refine the query in a perceptually intuitive way.…

Buch. Zustand: Neu. Neuware - I am honored to chair this International Workshop on Functionally st Graded Materials in the 21 Century: A Workshop on Trends and Forecasts, and would like to first express my sincere gratitude to everyone participating. The Mechanical Engineering Laboratory and the Japan International Science and Technology Exchange Center (JISTEC) have co-organized this workshop with the sponsorship of the Science and Technology Agency of Japan and the cooperation of the Association of Mechanical Technology. This workshop is an international conference to focus on functionally graded materials and the aim is to provide an overview of the present global technical trends and the future development of functionally graded materials over the next 10 years. I am very happy to see many researchers meeting together here - including seven researchers invited from abroad. During the three-day oral sessions, 36 research reports will be presented, and I'm sure I'm not the only one who is very anxious to hear and participate in the upcoming interesting discussions. At present, the Mechanical Engineering Laboratory is conducting fundamental and ground-breaking research in such major areas as materials science and technology, bioengineering, information & system science, advanced machine technology, energy technology, manufacturing technology and robotics. In particular, we consider research on materials science and technology to have the highest priority for the 21st century. and since 1996 have participated in the US-Japan joint research project, Precompetitive Processing and Characterization of Functionally Graded Materials.…

Buch. Zustand: Neu. Neuware - In the United States alone, the incidence of new cases of thoracic neoplasms is over 180,000. Each year, over 170,000 individuals are expected to die of their cancer. Lung cancer is the most common of the thoracic neoplasms. It is the leading cause of cancer death in both men and women, accounting for 28% of all cancer deaths in the United States. Thoracic Oncology provides an up-to-date and concise review of the various thoracic neoplasms and offers a better understanding of the biology, natural history, diagnosis and treatment of these malignancies. This book will be of particular interest to clinicians interested in thoracic neoplasms, to better understand and treat them.…
