Progress in Scale Modeling, Volume 2 builds on the success of Volume1asthedefinitivesourceofinformationonthispowerfulsimplifyingand clarifyingtoolusedbyscientistsandengineersacrossmanydisciplines.Thebook’s diverse slate of authors helps readers “see the forest, when there are many, many trees” by elucidating techniques used when it would be too expensive, or too difficult,totestasystemofinterestinthefield. Topicsaddressedinthecurrenteditioninclude scalemodeling tostudynatural disasters and its impacts on environment and structures, developing and testing energygenerationsystemsandmethods,andothers.Thisbookalso (cid:129) Enablesreaderstoevaluateessentialandsalientaspectsofprofoundlycomplex systems,mechanisms,andphenomenaatscale. (cid:129) Offers engineers and designers a new point of view, liberating creative and innovativeideasandsolutions. (cid:129) Serves the widest range of readers across the engineering disciplines and in scienceandmedicine. Volume 1 was a selection of seminal papers given at the first 5 sessions of the International Symposium on Scale Modeling (ISSM), which were held between 1988and2006.DuringtheinterveningyearsISSMVIandISSMVIIwereheldin 2009 and 2013, respectively. The papers in this volume represent those two later symposia. The International Scale Modeling Committee consists of worldwide v vi Preface researchers in scale modeling, and celebrated its 25th anniversary in 2013. The committee is interdisciplinary, attracting researchers from a broad range of scientificandengineeringdisciplines.
