Books Description:

Scholars have long recognized Lucretius's De Rerum Natura as an important allusive source for the Aeneid, but significant disagreement persists regarding the scope and purpose of Virgil's engagement with Epicurean philosophy. In Atomism in the Aeneid, Matthew M. Gorey investigates that engagement and argues that atomic imagery functions as a metaphor for cosmic and political disorder in Virgil's epic, associating the enemies of Aeneas and of Rome's imperial destiny with the haphazard, purposeless chaos of Epicurean atoms in the void. While nearly all of Virgil's allusions to atomism are constructed from Lucretian intertextual material, Gorey shows how the poet's negative reception of atomism draws upon a long and popular tradition of anti-atomist discourse in Greek philosophy that metaphorically likened the non-teleological cosmology of atomism to civic disorder and mob rule. By situating Virgil's atomic allusions within the tradition of philosophical opposition to Epicurean physics, Atomism in the Aeneid illustrates the deeply ideological nature of his engagement with Lucretius.

Books Description:

Aerodynamics of Wind Turbines is the established essential text for the fundamental solutions to efficient wind turbine design. Now in its third edition, it has been substantially updated with respect to structural dynamics and control. The new control chapter now includes details on how to design a classical pitch and torque regulator to control rotational speed and power, while the section on structural dynamics has been extended with a simplified mechanical system explaining the phenomena of forward and backward whirling modes. Readers will also benefit from a new chapter on Vertical Axis Wind Turbines (VAWT). Topics covered include increasing mass flow through the turbine, performance at low and high wind speeds, assessment of the extreme conditions under which the turbine will perform and the theory for calculating the lifetime of the turbine. The classical Blade Element Momentum method is also covered, as are eigenmodes and the dynamic behaviour of a turbine. The book describes the effects of the dynamics and how this can be modelled in an aeroelastic code, which is widely used in the design and verification of modern wind turbines. Furthermore, it examines how to calculate the vibration of the whole construction, as well as the time varying loads and global case studies.

When Aneira awakens to find she has been sprited away into the night by none other than the dread witch Baba Yaga, she is faced with a choice: help Baba Yaga find her sisters' magical skins and Aneira can go home to her family or refuse to help and lose her mother and sisters forever. The task is simple. She just has to steal the Lord of Winter’s heart by lulling him to sleep with the Harp of the Seven Winds. Once she has it, all Aneira has to do is lock it in a magic jar Baba Yaga gives her. After that, she’s free to go home. The only way to obtain the harp, however, is to succeed at the three tasks set forth by the winds themselves—winds that are bent on protecting the harp from mortal hands at all costs. But stealing the Lord of Winter’s heart turns out to be more complicated than Aneira realized, and she must decide whether returning to her family is worth the price of the world losing Winter forever.

Books Description:

Wind Forces in Engineering, Second Edition covers the various aspects, principles, and engineering applications of wind forces. This book is composed of 10 chapters and starts with an introduction to the history of wind forces. The subsequent chapters consider the wind speeds for various topographies; particular "shape factors" for general and special structures; oscillatory wind forces of a random or single-frequency type; and the dynamic response of structures to oscillatory wind forces. Other chapters deal with specific structures, such as buildings, bridges, towers, radar antennas, for static and dynamic wind loadings. The final chapter provides the Code of Practice which has been republished since 1972, including those for Australia, Canada, Great Britain and the U.S.A. These codes do not provide similar responses and are all essentially in a transitional state between the old static force concept and an improved statistical analysis to be based on more experimental evidence. This book will prove useful to engineers and researchers.

Books Description:

There are a number of books in the market about wind energy, turbine controllers, modelling and different aspects of integration of Wind Farm Power Plants ( WPP) to grids. But none of these books meets the expectations of design and field engineers/technicians to address directly the setting and design philosophy of different Intelligent Electronic Devices (IED) of WPP networks. This book provides practical applications of numerical relays for protection and control of different parts of onshore & offshore WPP network namely wind turbine generator, collector feeder and EHV interconnection transmission line to grid. In addition required changes to existing special protection system (SPS) and run-back scheme by adding a new WPP are discussed. The topology and characteristics of WPP networks are different from convectional one for both onshore and offshore WPP. In addition the fault current contribution from wind farm generators are low (1.1-1.2 pu). These causes significant challenge for setting and design of IEDs of WPP in order to meet the common industry practice requirement with respect to reliability, sensitivity, stability, security and grading coordination. The author believes that this book may be unique with respect to addressing these challenges and provision of the mitigation techniques to rectify the deficiencies of existing industry practice which otherwise have not been discussed for real systems in any other book. The content of this book have been successfully applied in the field for various WPPs projects and consequently can be used as a practical guideline for implementation for future projects. The content of the book covers Principal of Operation of WPP , Modelling of different com ponents of WPP, Short Circuit current and voltage characteristics of different type of wind turbine generators, Setting and Design of Protection systems of WPP Network , Design of Control systems of WPP, Lightening and Overvoltage Protection of WPP and Analysis of Disturbance on the WPP networks

Books Description:

Three important studies were initiated in the 1970s to investigate the relation ship between climatic variations and agriculture: by the National Delcnse University (1980) on Crop Yields and Climate Change to the Year 2000, by the U.s. Department of Transportation (1975) on Impacts of Climatic Change on the Biosphere and by the U.S. Department of Energy (1980) on Environmental and Societal Consequences of a Possible CO -Induced Climatic Change (the ClAP 2 study). These were pioneering projects in a young field. Their emphasis was on measuring likely impacts of climatic variations rather than on evaluating possible responses, and they focused on first-order impacts (e.g., on crop yields) rather than on higher-order effects on society. A logical next step was to look at higher-order effects and potential responses, as part of a more integrated approach to impact assessment. This was undertaken by the World Climate Impact Program (WCIP), which is directed by the United Nations Environment Program (UNEP). The WCIP is one of four aspects of the World Climate Program that was initiated in 1979. At a meeting in 1982, the Scientific Advisory Committee of WCIP accepted, in broad terms, a proposal from the International Institute for Applied Systems Analysis (IIASA) for an integrated climate impact assessment, with the proviso that the emphasis be on impacts in the agricultural sector. Martin Parry was asked to design and direct the project at IIASA. Funding was provided by UNEP, IIASA, the Austrian Government and the United Nations University.

History of Virtual Work Laws

Books Description:

The book presents a history of classical mechanics by focusing on issues of equilibrium. The historical point of view adopted here restricts attention to cases where the effectiveness of forces is assessed on the basis of the virtual motion of their points of application. For completeness, hints of the alternative approach are also referred, the Archimedean for ancient mechanics and the Newtonian for modern mechanics. The laws resulting from consideration of virtual motions are named laws of virtual work. The modern formulations of the principle of virtual work are only a particular form of them. The book begins with the first documented formulations of laws of virtual work in the IV century BC in Greece and proceeds to the end of the XIX century AD in Europe. A significant space is devoted to Arabic and Latin mechanics of Middle Ages. With the Renaissance it began to appear slightly different wordings of the laws, which were often proposed as unique principles of statics. The process reached its apex with Bernoulli and Lagrange in the XVIII century. The book ends with some chapters dealing with the discussions that took place in the French school on the role of the Lagrangian version of the law of virtual work and its applications to continuum mechanics.
