  • The intent of this book is to set the modern foundations of the theory of generalized curvature measures. This subject has a long history, beginning with J. Steiner (1850), H. Weyl (1939), H. Federer (1959), P. Wintgen (1982), and continues today with young and brilliant mathematicians. In the last decades, a renewal of interest in mathematics as well as computer science has arisen (finding new applications in computer graphics, medical imaging, computational geometry, visualization …).

  • 4 portance of collision detection extends to several areas like robot motion planning, dynamic simulation, virtual reality applications and it has been extensively studied in robotics, computational geometry, and computer graphics for more than a decade 3, 4, 11, 13, 17, 41, 43, 45, 51, 53, 63 . Yet, there is no practical, e cient algorithm available yet for general geometric models to perform collision detection in real time. Recently, Pentland has listed collision detection as one of the major bottlenecks towards real time virtual environment simulations 69 .

  • Every human possesses more than one virtually infallible form of identification. Known as biometrics, examples include fingerprints, iris and retinal scans, hand geometry, and other measures of physical characteristics and personal traits. Advances in computers and related technologies have made this a highly automated process through which recognition

  • Orthographic projections-that is, plans and sections-are one of the most valuable representational tools architects have at their disposal. They are an indispensable communication and design device. They have also contributed to a prominent digital fabrication method. With computer modeling, deriving sections is no longer a necessarily two-dimensional drawing exercise. In fact, it is no longer an exercise in projection at all but a process of taking cuts through a formed three-dimensional object.

  • In this paper, an investigation of nonregular TOFD indications acquired from RVHP tubes using experiments and computer simulation was performed in order to identify and distinguish TOFD signals by coarse grains from those by Primary Water Stress Corrosion Crack (PWSCC). For proper understanding of the nonregular TOFD indications, microstructural analysis of the RVHP tubes and prediction of signals scattered from the grains using Finite Element Method (FEM) simulation were performed.

  • Interests in Cu-Cr sub-nanometer systems have been increasing due to the recentlyfound icosahedral Cu12Cr cluster as a superatomic molecule, where the 3d-Cr and 4s-Cu electrons can phenomenologically form the 18-e molecular shell (1S2 1P6 1D10) of Cu12Cr. In this report, we set out to investigate the energetically-preferred geometries and stabilities of CunCr (n = 9÷11) clusters using the density-functional-theory calculations.

  • This book is a survey of abstract algebra with emphasis on algebra tinh.Do is online for students in mathematics, computer science, and physical sciences. The rst three or four chapters can stand alone as a one semester course in abstract algebra. However, they are structured to provide the foundation for the program linear algebra. Chapter 2 is the most di cult part of the book for group written in additive notation and multiplication, and the concept of coset is confusing at rst. Chapter 2 After the book was much easier as you go along....

  • This book, based on intensive research I have conducted since the late 1970s, is my attempt to cover in one monograph the modern theory of surface generation with a focus on kinematic geometry of surfacemachining on amultiaxis numerical control (NC) machine. Although the orientation of this book is toward computer-aided design (CAD) and computer-aidedmanufacturing (CAM), it is also useful for solving problems that relate to the generation of surfaces on machine tools of conventional design (for example, gear generators, and so forth)....

  • Although much of its discovery process is descriptive and qualitative, chemistry is fundamentally a quantitative science. It serves a wide range of human needs, activities, and concerns. The mathematical sciences provide the language for quantitative science, and this language is growing in many directions as computational science in general continues its rapid expansion. A timely opportunity now exists to strengthen and increase the beneficial impacts of chemistry by enhancing the interaction between chemistry and the mathematical sciences.

  • In order to achieve good reflectance performance through environmental and stress conditions seen in service, fiber-optic connectors must achieve and maintain physical contact between fiber cores. It is a given in the industry that ferrule endface geometry is critical to maintaining fiber core physical contact. The three critical attributes of endface geometry for physical contact (PC) connectors are radius of curvature, fiber protrusion/ recession, and apex offset. In angled physical contact (APC) connectors, the equivalent of apex offset is often referred to as dome offset....

  • Mathematical theories and methods and effective computational algorithms are crucial in coping with the challenges arising in the sciences and in many areas of their application. New concepts and approaches are necessary in order to overcome the complexity barriers particularly created by nonlinearity, high-dimensionality, multiple scales and uncertainty. Combining advanced mathematical and computational methods and computer technology is an essential key to achieving progress, often even in purely theoretical research.
