This book was developed while I was teaching graduate courses on analysis, design and optimization of structures, in the United States, Europe and Israel. Structural analysis is a main part of any design problem, and the analysis often must be repeated many times during the design process. Much work has been done on design-oriented analysis of structures recently and many studies have been published. The purpose of the book is to collect together selected topics of this literature and to present them in a unified approach. It meets the need for a general text covering the basic concepts and methods as well as recent developments in this area. This should prove useful to students, researchers, consultants and practicing engineers involved in analysis and design of structures. Previous books on structural analysis do not cover most of the material presented in the book. The book deals with the problem of multiple repeated analyses (reanalysis) of structures that is common to numerous analysis and design tasks. Reanalysis is needed in many areas such as structural optimization, analysis of damaged structures, nonlinear analysis, probabilistic analysis, controlled structures, smart structures and adaptive structures. It is related to a wide range of applications in such fields as Aerospace Engineering, Civil Engineering, Mechanical Engineering and Naval Architecture.

Example problems and methods of data analysis, together with general observations, are given. Smooth-slope runup results for both breaking and nonbreaking waves are presented in a set of curves similar to but revised from those in the Shore Protection Manual (SPM) (U.S. Army, Corps of Engineerings, Coastal Engineering Research Center, 1977). The curves are for structure slopes fronted by horizontal and 1 on 10 bottom slopes. The range of values of d sub s/H' sub o was extended to d sub s/H' sub o = 8; relative depth (d sub s/H' sub o) is important even for d sub s/H' sub o> 3 for waves which do not break on the structure slope. Rough-slope results are presented in similar curves if sufficient data were available. Otherwise, results are given as values of r, which is the ratio of rough-slope runup to smooth-slope runup. Scale-effect in runup is discussed.

The topic addressed in this volume lies within the study of sentence processing, which is one of the major divisions of psycholinguistics. The goal has been to understand the structure and functioning of the mental mechanisms involved in sentence comprehension. Most of the experimental and theoretical work during the last twenty or thirty years has focused on 'first-pass parsing', the process of assigning structure to a sentence as its words are encountered, one at a time, 'from left to right' . One important guiding idea has been to delineate the processing mechanisms by studying where they fai!. For this purpose we identify types of sentences which perceivers have trouble assigning structure to. An important class of perceptually difficult senten ces are those which contain temporary ambiguities. Since the parsing mechanism cannot tell what the intended structure is, it may make an incorrect guess. Then later on in the sentence, the structure assignment process breaks down, because the later words do not fit with the incorrect structural analysis. This is called a 'garden path' situation. When it occurs, the parsing mechanism must somehow correct itself, and find a different analysis which is compatible with the incoming words. This reanalysis process is the subject of the research reported here.

The papers in this volume are intended to exemplify the state of experimental psycho linguistics in the middle to later 1980s. Our over riding impression is that the field has come a long way since the earlier work of the 1950s and 1960s, and that the field has emerged with a renewed strength from a difficult period in the 1970s. Not only are the theoretical issues more sharply defined and integrated with existing issues from other domains ("modularity" being one such example), but the experimental techniques employed are much more sophisticated, thanks to the work of numerous psychologists not necessarily interested in psycholinguistics, and thanks to improving technologies unavailable a few years ago (for instance, eye-trackers). We selected papers that provide a coherent, overall picture of existing techniques and issues. The volume is organized much as one might organize an introductory linguistics course - beginning with sound and working "up" to mean ing. Indeed, the first paper, Rebecca Treiman's, begins with considera tion of syllable structure, a phonological consideration, and the last, Alan Garnham's, exemplifies some work on the interpretation of pro nouns, a semantic matter. In between are found works concentrating on morphemes, lexical structures, and syntax. The cross-section represented in this volume is by necessity incom plete, since we focus only on experimental work directed at under standing how adults comprehend and produce language. We do not include any works on language acquisition, first or second.

Inverse and crack identification problems are of paramount importance for health monitoring and quality control purposes arising in critical applications in civil, aeronautical, nuclear, and general mechanical engineering. Mathematical modeling and the numerical study of these problems require high competence in computational mechanics and applied optimization. This is the first monograph which provides the reader with all the necessary information. Delicate computational mechanics modeling, including nonsmooth unilateral contact effects, is done using boundary element techniques, which have a certain advantage for the construction of parametrized mechanical models. Both elastostatic and harmonic or transient dynamic problems are considered. The inverse problems are formulated as output error minimization problems and they are theoretically studied as a bilevel optimization problem, also known as a mathematical problem with equilibrium constraints. Beyond classical numerical optimization, soft computing tools (neural networks and genetic algorithms) and filter algorithms are used for the numerical solution. The book provides all the required material for the mathematical and numerical modeling of crack identification testing procedures in statics and dynamics and includes several thoroughly discussed applications, for example, the impact-echo nondestructive evaluation technique. Audience: The book will be of interest to structural and mechanical engineers involved in nondestructive testing and quality control projects as well as to research engineers and applied mathematicians who study and solve related inverse problems. People working on applied optimization and soft computing will find interesting problems to apply to their methods and all necessary material to continue research in this field.

This book proposes and validates a number of methods and shortcuts for frugal engineers, which will allow them to significantly reduce the computational costs for analysis and reanalysis and, as a result, for structural design processes. The need for accuracy and speed in analyzing structural systems with ever-tighter design tolerances and larger numbers of elements has been relentlessly driving forward research into methods that are capable of analyzing structures at a reasonable computational cost. The methods presented are of particular value in situations where the analysis needs to be repeated hundreds or even thousands of times, as is the case with the optimal design of structures using different metaheuristic algorithms. Featuring methods that are not only applicable to skeletal structures, but by extension also to continuum models, this book will appeal to researchers and engineers involved in the computer-aided analysis and design of structures, and to software developers in this field. It also serves as a complement to previous books on the optimal analysis of large-scale structures utilizing concepts of symmetry and regularity. Further, its novel application of graph-theoretical methods is of interest to mathematicians.

The architecture of the human language faculty has been one of the main foci of the linguistic research of the last half century. This branch of linguistics, broadly known as Generative Grammar, is concerned with the formulation of explanatory formal accounts of linguistic phenomena with the ulterior goal of gaining insight into the properties of the 'language organ'. The series comprises high quality monographs and collected volumes that address such issues. The topics in this series range from phonology to semantics, from syntax to information structure, from mathematical linguistics to studies of the lexicon.

This volume centers on three important theoretical concepts for the study of language change and the ways in which language structure emerges and turns into new structure: reanalysis, actualization, and indexicality. Reanalysis is a part of ongoing everyday language use, a process through which language is reproduced and changed. Actualization refers to the processes through which a reanalyzed structure spreads throughout single communities and society. Indexicality covers the way in which parts of a linguistic system can point to other parts of the system, both syntagmatically and paradigmatically. The inclusion of indexicality leads to fine-grained analysis in morphology, word order, and constructional syntax.
