The Tower of Pisa History Construction and Geotechnical Stabilization

The Tower of Pisa History Construction and Geotechnical Stabilization

The Leaning Tower of Pisa is known worldwide for its five-degree lean. The Tower is the Campanile of the Cathedral which together with the Baptistry and Cemetery form a breath-taking collection of monuments which are regarded as supreme examples of early Renaissance Romanesque architecture. In March 1990 the Tower was closed to the public as it was declared unsafe and close to collapse. A Commission was set up by the Italian Government with the task of developing and implementing stabilization measures. This book begins with a brief description of the history of the Tower and its construction. The reader is then introduced to the huge challenges faced by the Commission in designing and implementing appropriate stabilization measures whilst at the same time satisfying the demanding requirements of conserving a world heritage monument. In particular two historical studies are described which proved to be most valuable in arriving at suitable stabilization measures. The first was a deduction of the history of inclination of the tower during and subsequent to construction. The results of this study were used to calibrate a sophisticated numerical model of the tower and the underlying very soft ground which proved vital in evaluating the effectiveness of various stabilization schemes. The second study was of measurements of movement made since 1911. This latter study revealed an unexpected mechanism of foundation movement which proved crucial in developing the temporary and permanent stabilization measures and which resulted in the Tower being re-opened to the public in June 2001. The book will appeal to both professionals and students in the fields of Architecture and Civil Engineering. It will also interest specialised audiences of geotechnical engineers and conservation architects. It may also be of wider interest to anyone planning to visit Pisa or who is intrigued as to what caused the Tower to lean and how it was stabilized. | The Tower of Pisa History Construction and Geotechnical Stabilization

Crisis in Sociology The Need for Darwin

Crisis in Sociology The Need for Darwin

Crisis in Sociology presents a compelling portrait of sociology's current troubles and proposes a controversial remedy. In the authors' view sociology's crisis has deep roots traceable to the over-ambitious sweep of the discipline's founders. Generations of sociologists have failed to focus effectively on the tasks necessary to build a social science. The authors see sociology's most disabling flaw in the failure to discover even a single general law or principle. This makes it impossible to systematically organize empirical observations guide inquiry by suggesting falsifiable hypotheses or form the core of a genuinely cumulative body of knowledge. Absent such a theoretical tool sociology can aspire to little more than an amorphous mass of hunches and disconnected facts. The condition engenders confusion and unproductive debate. It invites fragmentation and predation by applied social disciplines such as business administration criminal justice social work and urban studies. Even more dangerous are incursions by prestigious social sciences and by branches of evolutionary biology that constitute the frontier of the current revolution in behavioral science. Lopreato and Crippen argue that unless sociology takes into account central developments in evolutionary science it will not survive as an academic discipline. Crisis in Sociology argues that participation in the new social science exemplified by thriving new fields such as evolutionary psychology will help to build a vigorous scientific sociology. The authors analyze research on such subjects as sex roles social stratification and ethnic conflict showing how otherwise disconnected features of the sociological landscape can in fact contribute to a theoretically coherent and cumulative body of knowledge. | Crisis in Sociology The Need for Darwin

Shipboard Electrical Power Systems

Island Power Systems

Island Power Systems

A major concern of island power systems is frequency stability. A power system is said to be frequency stable if its generators are able to supply their loads at a frequency within acceptable limits after a disturbance. Frequency instability occurs if load-generation imbalances are not corrected in appropriate manner and time. Since island power systems are more sensitive to frequency instability than large ones due to the smaller number of generators online and the lower inertia they require a larger amount of primary reserve per generator. This book provides a worldwide overview of island power systems describing their main features and issues. Split into two parts the first part examines the technical operation and in particular frequency stability of island power systems and its technical solutions including more efficient underfrequency load-shedding schemes. The chapters explore both conventional and advanced load-shedding schemes and consider the improvement of these schemes by making them more robust and efficient. Advanced devices are modelled and analyzed to enhance frequency stability and reduce the need for load shedding. In the second part the economic operation of island power systems is explored in detail. For that purpose regulations and economic operations (centralized vs. market scheme) are reviewed by the authors. The authors discuss models for renewable energy sources and for advanced devices and systems such as demand-side management energy storage systems and electric vehicles. This book will be critical reading to all researchers and professionals in power system planning and engineering electrical/power delivery RES and control engineering. It will also be of interest to researchers in signal processing and telecommunications and renewable energy as well as power system utility providers.

SPICE for Power Electronics and Electric Power

SPICE for Power Electronics and Electric Power

Power electronics can be a difficult course for students to understand and for professors to teach. Simplifying the process for both SPICE for Power Electronics and Electric Power Third Edition illustrates methods of integrating industry standard SPICE software for design verification and as a theoretical laboratory bench. Helpful PSpice Software and Program Files Available for Download Based on the author Muhammad H. Rashid’s considerable experience merging design content and SPICE into a power electronics course this vastly improved and updated edition focuses on helping readers integrate the SPICE simulator with a minimum amount of time and effort. Giving users a better understanding of the operation of a power electronics circuit the author explores the transient behavior of current and voltage waveforms for each and every circuit element at every stage. The book also includes examples of all types of power converters as well as circuits with linear and nonlinear inductors. New in this edition: Student learning outcomes (SLOs) listed at the start of each chapter Changes to run on OrCAD version 9. 2 Added VPRINT1 and IPRINT1 commands and examples Notes that identify important concepts Examples illustrating EVALUE GVALUE ETABLE GTABLE ELAPLACE GLAPLACE EFREQ and GFREQ Mathematical relations for expected outcomes where appropriate The Fourier series of the output voltages for rectifiers and inverters PSpice simulations of DC link inverters and AC voltage controllers with PWM control This book demonstrates techniques of executing power conversions and ensuring the quality of the output waveforms rather than the accurate modeling of power semiconductor devices. This approach benefits students enabling them to compare classroom results obtained with simple switch models of devices. In addition a new chapter covers multi-level converters. Assuming no prior knowledge of SPICE or PSpice simulation the text provides detailed step-by-step instructions on how to draw a schematic of a circuit execute simulations and view or plot the output results. It also includes suggestions for laboratory experiments and design problems that can be used for student homework assignments.
