This book is made of the proceedings of EUROCODE 1992 which was held in Udine (Italy) at the CISM, October 27 - 30, 1992. EUROCODE ’92 is a continuation as well as an extension of the previous colloquia Trois Journèes sur le codage and EUROCODE ’90, whose proceedings appeared as Lecture Notes in Computer Science (Volumes 388 and 514). The aim of EUROCODE ’92 was to attract high level research papers and to encourage interchange of ideas among the areas of coding theory and related fields which share the same tools for applications in the science of communications, theoretical computer science, software engineering and mathematics. Then the book is characterized by a very broad spectrum, ranging from combinatories or algebraic geometry to implementation of coding algorithms. There were about 90 participants to the conference, from the academic and industrial worlds; 53 conferences were selected. The submitted full-papers were separately refereed for publication by at least two international referees.

Applies to the design of building and civil engineering structures in plain, reinforced and pre-stressed concrete. The code (for convenience referred to as EC2) is written in several parts: EN 1992 - 1 - 1; EN 1992 - 1 - 2; EN 1992 - 2; and EN 1992 - 3.

This is a review of developments in the behaviour and design of steel structures in seismic areas. The proceedings look at the analytical and experimental research on the seismic response of steel structures, and cover topics such as global behaviour and codification, design and application.

With the gradual development of rules for designing against instability the idea emerged, in London, in 1974 to hold an International Colloquium treating every aspect of structural instability of steel structures. There have been 17 International Colloquia Stability Sessions around the world, starting with the first one in Paris in 1972, until with the last one in Nagoya in 1997. In Nagoya it was decided to continue the series of travelling colloquia by launching the Sixth Colloquium in September 1999 with the First Session to be held at the "Politehnica" University of Timişoara, România, which will be followed by another in the year 2000 at the Gediminas Technical University in Vilnius, Lithuania, a third one during SSRC's Year 2000 Annual Meeting in the US, and a fourth one in Australia or New Zealand. At present important research projects are in progress around the world, like SAC Joint Venture Project in USA, INCO-COPERNICUS "RECOS" in Europe and others, which are devoted to improve and develop new methods for the safety design of steel structures in seismic zones. Special attention is paid in Europe, USA and Japan to improve the design codes and detailing of seismic resistant steel structures. This was the reason to organise the Session of Nagoya as "Stability and Ductility of Steel Structures" Colloquium. Romania is also a strong seismic territory and therefore, the topic of the Timişoara Session covered both stability and ductility problems. The technical programme of the SDSS'99 Colloquium in Timişoara has been split into nine working sessions.

This book forms the proceedings of the International Workshop organised by the European Convention for Constructional Steelwork held in Timisoara, Romania, in June 1994. It presents the latest progress in theoretical and experimental research on the behaviour of steel structures in seismic areas, taking into account the basic problems of local and global ductility, codification, design and applications. It relates strongly to the activities on international codification taking place in Europe.

The third edition of this definitive and popular book continues to pursue the question: what is the most efficient way to pack a large number of equal spheres in n-dimensional Euclidean space? The authors also examine such related issues as the kissing number problem, the covering problem, the quantizing problem, and the classification of lattices and quadratic forms. There is also a description of the applications of these questions to other areas of mathematics and science such as number theory, coding theory, group theory, analogue-to-digital conversion and data compression, n-dimensional crystallography, dual theory and superstring theory in physics. New and of special interest is a report on some recent developments in the field, and an updated and enlarged supplementary bibliography with over 800 items.
