  • This textbook covers all the standard introductory topics in classical mechanics, including Newton's laws, oscillations, energy, momentum, angular momentum, planetary motion, and special relativity. It also explores more advanced topics, such as normal modes, the Lagrangian method, gyroscopic motion, fictitious forces, 4-vectors, and general relativity. It contains more than 250 problems with detailed solutions so students can easily check their understanding of the topic. There are also over 350 unworked exercises which are ideal for homework assignments.

  • The solutions as presented generally just provide a guidance to solving the problems, rather than step by step manipulation, and leave much to the students to work out for themselves, of whom much is demanded of the basic knowledge in physics. Thus the series would provide an invaluable complement to the textbooks. The present volume for Mechanics which consists of three parts Newtonian Mechanics, Analytical Mechanics, and Special Relativity contains 410 problems.

  • In this paper we consider a combinatorial optimization problem that is similar to the bottleneck traveling salesman problem. We show that an optimal tour for this problem is pyramidal tour (1, 3, 5,…, n,…, 6, 4, 2) or consists of some pyramidal subtours. The above 7methods can be extended to complete bipartite graphs. 1. Problem statement It is well-known that the traveling salesman problem (TSP) is strongly NP-hard (cf. [1], p. 353). But for some special cases of the TSP can be solvable in polynomial time. ...

  • We notion of argue that in domains can be where it a strong can be Mann and Moore [1981], on the other hand, while assembling texts dynamically to suit their audience, do so by "over-generating" the set of facts that will be related, and then passing them all through a special filter, leaving out those that are judged to be already known to the audience and letting through those that are new. McKeown [1981] uses a similar technique -- her generator, like Mann and Moore's, must examine every potentially mentionable object in the domain data base and make...

  • The purpose of the special parasession on "Interactive Man/Machine Discourse" is to discuss some critical issues in the design of (computer-based) interactive natural language processing systems. This panel will be addressing the question of how the purpose of the interaction, or "problem context" affects what is said and how it is interpreted. Each of the panel members brings a different orientation toward the study of language to this question.

  • This contribution attempts a conceptual and practical introduction into the principles of wiring or constructing special machines for language processing tasks instead of programming a universal machine. C o n s t r u c t i o n w o u l d in principle provide higher descriptive adequacy in comp u t a t i o n a l l y based linguistics. After all, our heads do not apply programs on stored symbol arrays but are a p p r o p r i a t e l y wired for understanding or producing language.

  • Systemic grammar has been used for AI text generation work in the past, but the Implementations have tended be ad hoc or inefficient. This paper presents an approach to systemic text generation where AI problem solving techniques are applied directly to an unadulterated systemic grammar. This approach is made possible by a special relationship between systemic grammar and problem solving: both are organized primarily as choosing from alternatives. The result is simple, efficient text generation firmly based in a linguistic theory. ...

  • This text offers 25 topic-based units, each covering a key area of IT. There is a variety of texts and visual material, taken from textbooks, newspapers, computing magazines, web pages, manuals, and advertisements. The course revises and practises grammar and functions appropriate to the needs of IT specialists at intermediate level, developing all four skills, with the main emphasis on reading. Most units end with longer specialist reading texts. These are intentionally challenging, and can be used either for homework or self-study.

  • Multi-word verbs, or phrasal verbs as they are often referred to, present a very special problem. English can make verb and particle (preposition or adverb) combinations easily and freely. The word particle has been used throughout this book, in order to avoid having to make the adverb/preposition distinction (to most students, the word after the verb in a multi-word verb is always a preposition).

  • Evolutionary algorithms are a type of general problem solvers that can be applied to many difficult optimization problems. Because of their generality, these algorithms act similarly like Swiss Army knife (Michalewicz & Fogel, 2004) that is a handy set of tools that can be used to address a variety of tasks. In general, a definite task can be performed better with an associated special tool.
