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

Power Engineering Advances and Challenges Part B: Electrical Power

Traditionally power engineering has been a subfield of energy engineering and electrical engineering which deals with the generation transmission distribution and utilization of electric power and the electrical devices connected to such systems including generators motors and transformers. Implicitly this perception is associated with the generation of power in large hydraulic thermal and nuclear plants and distributed consumption. Faced with the climate change phenomena humanity has had to now contend with changes in attitudes in respect of environment protection and depletion of classical energy resources. These have had consequences in the power production sector already faced with negative public opinions on nuclear energy and favorable perception of renewable energy resources and about distributed power generation.

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.
