Introduction to Set Theory and Topology describes the fundamental concepts of set theory and topology as well as its applicability to analysis, geometry, and other branches of mathematics, including algebra and probability theory. Concepts such as inverse limit, lattice, ideal, filter, commutative diagram, quotient-spaces, completely regular spaces, quasicomponents, and cartesian products of topological spaces are considered. This volume consists of 21 chapters organized into two sections and begins with an introduction to set theory, with emphasis on the propositional calculus and its application to propositions each having one of two logical values, 0 and 1. Operations on sets which are an...

Św. Kazimierz, a raczej jego wizerunek zachowany w słowie pisanym, jak w dziełach sztuk wizualnych, jest tematem tej pracy. To opowieść o dziejach świętego z rodu Jagiellonów, obejmująca okres od 1520 roku – początku procesu kanonizacyjnego słynącego świętością królewicza – do końca XVIII wieku. Celem pracy jest pokazanie, jak pobożność do św. Kazimierza nabierała czytelnych form; rekonstrukcja genezy jego wizerunku, różnorodności ikonograficznej, symboliki i znaczeń teologicznych z nim związanych. Teksty dotyczące św. Kazimierza i jego przedstawienia pozwalają zrozumieć, jak w kontekście konkretnej epoki postrzegano jego świętość i jakie było jego m...
This comprehensive treatment of ultrawideband (UWB) antennas and time-domain microwave engineering serves as an invaluable practical reference for anyone involved in antenna and RF design work. This authoritative volume enables readers to select the proper UWB antennas for their applications, design and analyze UWB antennas, and integrate these antennas in an RF system. By applying time-domain thinking to problems of practical interest, the reader will not only learn how to build and analyze antennas, but also understand them at the most fundamental level. This second edition is updated and expanded throughout, providing readers with a history of antennas, numerous new problem sets and worked examples, along with new information on plotting time-domain field lines, time-domain reflectometry, matching techniques, and more. This book also addresses system issues like spectral control and antenna efficiency.
The acclaimed historian demonstrates a link between climate change and social unrest across the globe during the mid-17th century. Revolutions, droughts, famines, invasions, wars, regicides, government collapses—the calamities of the mid-seventeenth century were unprecedented in both frequency and severity. The effects of what historians call the "General Crisis" extended from England to Japan and from the Russian Empire to sub-Saharan Africa and the Americas. In this meticulously researched volume, historian Geoffrey Parker presents the firsthand testimony of men and women who experienced the many political, economic, and social crises that occurred between 1618 to the late 1680s. He also incorporates the scientific evidence of climate change during this period into the narrative, offering a strikingly new understanding of the General Crisis. Changes in weather patterns, especially longer winters and cooler and wetter summers, disrupted growing seasons and destroyed harvests. This in turn brought hunger, malnutrition, and disease; and as material conditions worsened, wars, rebellions, and revolutions rocked the world.
This volume contains the proceedings of the 16th International Symposium on Mathematical Foundations of Computer Science, MFCS '91, held in Kazimierz Dolny, Poland, September 9-13, 1991. The series of MFCS symposia, organized alternately in Poland and Czechoslovakia since 1972, has a long and well established tradition. The purpose of the series is to encourage high-quality research in all branches of theoretical computer science and to bring together specialists working actively in the area. Principal areas of interest in this symposium include: software specification and development, parallel and distributed computing, logic and semantics of programs, algorithms, automata and formal languages, complexity and computability theory, and others. The volume contains 5 invited papers by distinguished scientists and 38 contributions selected from a total of 109 submitted papers.
