The principle of Occam’s razor loosely translates to “the simplest solution is often the best”. The author of Kinematic Geometry of Surface Machining utilizes this reductionist philosophy to provide a solution to the highly inefficient process of machining sculptured parts on multiaxis NC machines. He has developed a method to quickly calculate the necessary parameters, greatly reduce trial and error, and achieve efficient machining processes by using less input information, and in turn saving a great deal of time.

The genesis of this book began on the sunny shores of southern France in September 1993. For five days in the delightful Mediterranean coastal town of La Londe Les Maures, a gathering occurred of a group of scientists interested in furthering both the understanding and use of thermal infrared (TIR) remote sensing data for analysis of land surface processes.

Tools shape how we think; when the only tool you have is an axe, everything resembles a tree or a log. The rapid advances in instrumentation in the last decade, which allow us to measure and manipulate individual molecules and structures on the nanoscale, have caused a paradigm shift in the way we view molecular behavior and surfaces. The microscopic details underlying interfacial phenomena have customarily been inferred from in situ measurements of macroscopic quantities. Now we can see and “finger” physical and chemical processes at interfaces.

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 computeraided design (CAD) and computeraidedmanufacturing (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)....

The machining of complex sculptured surfaces is an important technological topic in modern manufacturing, namely in the molds and dies sector. Today, this sector, with great importance to automotive, aircraft and others advanced industries, is placed in all industrialized or emerging countries. In the recent past, the traditional technology employed in molds and dies manufacture was a combination of con ventional milling and electrodischarge machining (EDM) or electrochemical machining (ECM).

In this paper we will prove the CalabiYau conjectures for embedded surfaces (i.e., surfaces without selfintersection). In fact, we will prove considerably more. The heart of our argument is very general and should apply to a variety of situations, as will be more apparent once we describe the main steps of the proof later in the introduction.

We study the integral points on surfaces by means of a new method, relying on the Schmidt Subspace Theorem. This method was recently introduced in [CZ] for the case of curves, leading to a new proof of Siegel’s celebrated theorem that any aﬃne algebraic curve deﬁned over a number ﬁeld has only ﬁnitely many Sintegral points, unless it has genus zero and not more than two points at inﬁnity. Here, under certain conditions involving the intersection matrix of the divisors at inﬁnity, we shall conclude that the integral points on a surface all lie on a curve. We shall...

The theory of polyhedral surfaces and, more generally, the ﬁeld of discrete diﬀerential geometry are presently emerging on the border of diﬀerential and discrete geometry. Whereas classical diﬀerential geometry investigates smooth geometric shapes (such as surfaces), and discrete geometry studies geometric shapes with a ﬁnite number of elements (polyhedra), the theory of polyhedral surfaces aims at a development of discrete equivalents of the geometric notions and methods of surface theory. The latter appears then as a limit of the reﬁnement of the discretization. ...

In this paper, we study the growth of sX(L), the number of simple closed geodesics of length ≤ L on a complete hyperbolic surface X of finite area. We also study the frequencies of different types of simple closed geodesics on X and their relationship with the WeilPetersson volumes of moduli spaces of bordered Riemann surfaces.

Annals of Mathematics We study the motion of an incompressible perfect liquid body in vacuum. This can be thought of as a model for the motion of the ocean or a star. The free surface moves with the velocity of the liquid and the pressure vanishes on the free surface. This leads to a free boundary problem for Euler’s equations, where the regularity of the boundary enters to highest order. We prove local existence in Sobolev spaces assuming a “physical condition”, related to the fact that the pressure of a ﬂuid has to be positive. ...

In this volume I present some examples of Basic Concepts, Examination of Functions, Level Curves and Level Surfaces and Description of Curves, cf. also Calculus 2b, Functions of Several Variables. Since my aim also has been to demonstrate some solution strategy I have as far as possible structured the examples according to the following form A Awareness, i.e. a short description of what is the problem. D Decision, i.e. a reflection over what should be done with the problem. I Implementation, i.e. where all the calculations are made. C Control, i.e. a test of the result.

Pigment epitheliumderived factor (PEDF), a potent blocker of angiogenesis in vivo, and of endothelial cell migration and tubule formation, binds with high affinity to an as yet unknown protein on the surfaces of endothelial cells. Given that protein fingerprinting suggested a match of a 60 kDa PEDFbinding protein in bovine retina withBos taurusF1ATP synthase bsubunit, and that F1FoATP synthase components have been identified recently as cellsurface receptors, we examined the direct binding of PEDF to F1. ...

The main objective of this work is to develop efficient techniques to couple solutions for performance of reservoir and surface facilities, which is a fundamental step for the development of management routines and for optiinization of total system periormance. Use of conventional techniques for fullfield models can be very computation time intensive and, therefore, such models are either rarely used or they are simplified by handling surface facilities explicitly.

This paper addresses a datadriven surface realisation model based on a largescale reversible grammar of German. We investigate the relationship between the surface realisation performance and the character of the input to generation, i.e. its degree of underspeciﬁcation. We extend a syntactic surface realisation system, which can be trained to choose among word order variants, such that the candidate set includes active and passive variants.

We present a discourselevel Tree Adjoining Grammar which tightly integrates syntax and discourse levels, including a representation for discourse entities. We show that this technique makes it possible to extend an optimisation algorithm used in natural language generation (polarity ﬁltering) to the discourse level. We implemented the grammar in a surface realizer and show that this technique can be used to reduce the search space by ﬁltering out referentially incoherent solutions.
