The book contains research results obtained by applying Bejan's Constructal Theory to the study and therefore the optimization of fins, focusing on T-shaped and Y-shaped ones. Heat transfer from finned surfaces is an example of combined heat transfer natural or forced convection on the external parts of the fin, and conducting along the fin. Fin's heat exchange is rather complex, because of variation of both temperature along the fin and convective heat transfer coefficient. Furthermore possible presence of more fins invested by the same fluid flow has to be considered. Classical fin theory tried to reduce the coupled heat transfer problem to a one-dimensional problem by defining an average ...
Prior to Russia’s invasion of Ukraine on 24 February 2022, Ukraine had made significant progress in implementing ambitious regional development and decentralisation reforms. These reforms resulted in the creation of 1 469 amalgamated municipalities, the establishment of an elaborate multi-level regional development planning framework, as well as a significant increase in local public service delivery, and public funding for regional and local development.
The current book provides a final report of activity performed by the COST 290 Action, ‘‘Traffic and QoS Management in Wireless Multimedia Networks,’’ which ran from March 10, 2004, until June 3, 2008. After an introduction to the COST framework and the Action’s survey time-frame and activities, the main part of the book addresses a number of technical issues, which are structured into several chapters. All those issues have been carefully investigated by the COST 290 community during the course of the project – the information presented in this book can be regarded as ultimate for each particular topic; every open research issue addressed in the book is described carefully, corr...
The Balkan countries have been looking for good examples and ideas to pursue development and internal integration in destabilized and ethnically complex and conflicting areas. This book about transformation in the framework of European outlines the path of the Balkans to European integration.
The monograph Drobci ledenodobnega okolja ("Fragments of Ice Age environments") presents a compilation of seventeen chapters in which experts from different scientific fields discuss specific topics related to the Ice Age in Europe. Ten of them are devoted to the presentation, analysis and interpretation of palaeontological data concerning various large mammal species ranging from mastodon and mammoth to the cave hyena, ibex, cave lion and bears, with the emphasis being placed on the cave bear. Several chapters address the topic of Last Glacial climatic conditions in the Southeastern Alps by studying fossil micromammal and palaeobotanical remains as well as geoarchaeologiocal data. A special...
