  • Although many other models of concurrent and distributed systems have been developed since the introduction in 1964 Petri nets are still an essential model for concurrent systems with respect to both the theory and the applications. The main attraction of Petri nets is the way in which the basic aspects of concurrent systems are captured both conceptually and mathematically. The intuitively appealing graphical notation makes Petri nets the model of choice in many applications.

  • The benefit-to-risk ratio of blood products needs constant evaluation. Blood products, as therapeutic agents, have had the test of time but lack the evidence we expect from other medicinals. Blood, an organ, is used as a pharmaceutical agent by the medical profession, due to the achievements in collection, processing, banking, and distribution. The fact that the most common risk of blood transfusion isblood delivery error supports the notion that blood is handled as a pharmaceutical agent.

  • This book aims to explain the basics of graph theory that are needed at an introductory level for students in computer or information sciences. To motivate students and to show that even these basic notions can be extremely useful, the book also aims to provide an introduction to the modern field of network science. Mathematics is often unnecessarily difficult for students, at times even intimidating.

  • We will begin our discussion by talking about false positives and false negatives, which are ever present factors in the life of an intrusion analyst. We will then discuss the notion of Events of Interest (EOI), and their relevance to the event analysis process. We will also go over techniques for judging the severity of a particular event. Additionally, we will propose a way to handle long term conditions that might result from a prolonged exposure to attacks.

  • The world is changing quickly, and our models of learning, communicating, and acting must change accordingly. Throughout society we must rethink basic notions of how we define and accomplish our goals in a complex and changing environment, including how we prepare ourselves for professional careers. This book is an effort in that direction for students in natural resource management. It is a response to some of the challenges we perceive students will face in the early twenty-first century, and it is a practice field on which they may begin to develop their skills....

  • The main contribution of this paper is that it applies a new measure for competition, called the Boone indicator (see also Boone, 2001; Bikker and Van Leuvensteijn, 2008; Van Leuvensteijn et al., 2007). The basic notion underlying this indicator is that in a competitive market, more efficient companies are likely to gain market shares. Hence, the stronger the impact of efficiency on market shares is, the stronger is competition.

  • This book is based on lectures delivered over the years by the author at the Universit´e Pierre et Marie Curie, Paris, at the University of Stuttgart, and at City University of Hong Kong. Its two-fold aim is to give thorough introductions to the basic theorems of differential geometry and to elasticity theory in curvilinear coordinates. The treatment is essentially self-contained and proofs are complete.

  • Tree Adjoining G r a m m a r (TAG) is u formalism for natural language grammars. Some of the basic notions of T A G ' s were introduced in [Jo~hi,Levy, mad Takakashi I~'Sl and by [Jo~hi, l ~ l . A detailed investigation of the linguistic relevance of T A G ' s has been carried out in IKroch and Joshi,1985~. In this paper, we will describe some new results for TAG's, espe¢ially in the following areas: (I) parsing complexity of TAG's, (2) some closure results for TAG's, and (3) the relationship to Head grammars. ...

  • The purpose of this chapter is largely to serve as an accessible introduction or a refresher of basic notions regarding analytic functions. We start by recalling the elementary theory of functions and their singularities in a style tuned to the needs of analytic combinatorics. Cauchy’s integral formula expresses coefficients of analytic functions as contour integrals. Suitable uses of Cauchy’s integral formula then make it possible to estimate such coefficients by suitably selecting an appropriate contour of integration.

  • By exploring the relationship between parsing and deduction, a new and more general view of chart parsing is obtained, which encompasses parsing for grammar formalisms based on unification, and is the basis of the Earley Deduction proof procedure for definite clauses. The efficiency of this approach for an interesting class of grammars is discussed. 1. I n t r o d u c t i o n The aim of this paper is to explore the relationship between parsing and deduction. The basic notion, which goes back to Kowaiski (Kowalski, 1980} and Colmerauer {Colmeraucr, 1978), h'zs seen a very...

  • This chapter introduces basic concepts needed for the study and description of morphologically complex words. Since this is a book about the particular branch of morphology called word- formation, we will first take a look at the notion of ‘word’. We will then turn to a first analysis of the kinds of phenomena that fall into the domain of word-formation, before we finally discuss how word-formation can be distinguished from the other sub-branch of morphology, inflection.

  • an one learn linear algebra solely by solving problems? Paul Halmos thinks so, and you will too once you read this book. The Linear Algebra Problem Book is an ideal text for a course in linear algebra. It takes the student step by step from the basic axioms of a field through the notion of vector spaces, on to advanced concepts such as inner product spaces and normality. All of this occurs by way of a series of 164 problems, each with hints and, at the back of the book, full solutions. This book is a marvelous example of how...

  • There is mixed opinion on the likelihood of continued long-term increase in life expectancy. Most demographers including Vaupel and Lee (44, 45, 62) are optimistic about continued increases in life expectancy and decreases in mortality among older persons. Olshansky (63) has been a promoter of the idea that future increases will be minimal.
