Book Synopsis Flexoelectricity in Liquid Crystals by : Agnes Buka
Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.
Book Synopsis Multi-party Elections in Africa by : Michael Cowen
Download or read book Multi-party Elections in Africa written by Michael Cowen and published by . This book was released on 2002 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains electoral studies of multiparty politics in 14 African countries during the 1990s. Most are about national elections in Anglophone Africa. There are also less well-known examples from Sudan, Ethiopia and Guinea Bissau. The collection also features studies of the local elections in Namibia and of a significant by-election in Malawi. The multiparty period had been put, wherever possible, within the historical context of earlier elections in Africa. Questions addressed include: how did incumbent governing regimes learn to live with multiparty politics? Why have some elections been so closely fought and others have suffered from apathy? Why has there been relatively open political expression and activity when the elections have increased the political and economic manipulation by incumbent governments? Why have the elections of the 1990s been so marked by local and ethnic variations? To what extent did this wave of democracy result from pressure from donor countries?

Book Synopsis Spaces and Identities in Border Regions by : Christian Wille
Download or read book Spaces and Identities in Border Regions written by Christian Wille and published by transcript Verlag. This book was released on 2015-11-30 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spatial and identity research operates with differentiations and relations. These are particularly useful heuristic tools when examining border regions where social and geopolitical demarcations diverge. Applying this approach, the authors of this volume investigate spatial and identity constructions in cross-border contexts as they appear in everyday, institutional and media practices. The results are discussed with a keen eye for obliquely aligned spaces and identities and relinked to governmental issues of normalization and subjectivation. The studies base upon empirical surveys conducted in Germany, France, Belgium and Luxembourg.

Book Synopsis Pipeline Risk Assessment by : W. Kent Muhlbauer
Download or read book Pipeline Risk Assessment written by W. Kent Muhlbauer and published by . This book was released on 2015-02-01 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: The optimum management of risks emerges from the best understanding of risks. Risk understanding is now available to all, via efficient and intuitive risk assessment. This book presents the definitive approach to assessing risks from pipelines?an approach that overcomes the limitations of previous methodologies.As the definitive approach, the methodology must:*Provide clarity?generating immediately useful information to decision-makers*Be comprehensive and complete*Capture and integrate real world processes*Dispel myths arising from risk assessment past practice*Remove unnecessary complexity that interferes with understanding risk*Be cost-effective to create, apply, and manage.As with the author?s previous works, the recommended methodology detailed here is a practical, easy-to-apply approach to measuring risks associated with operating any type of pipeline in any environment. Risk assessment need not be a complex academic exercise. It should be a straightforward practice, used by ? and useful to ? any and all stakeholders in a pipeline?s operation.Some specific features of the definitive approach include:*The three critical determinants of failure probability?exposure, mitigation, resistance.*Using inspection information directly, intuitively, and efficiently in a risk assessment.*Measuring damage potential separately from failure potential.*Automatic and intuitive incorporation of interacting threats?weaknesses overlapping failure mechanisms.*The role of time-to-failure estimation in modeling corrosion and cracking.*Using hazard zones to understand potential consequence scenarios.*Representing all possible consequence scenarios with a manageable set.*The best use?not the most common use?of historical incident statistics*The essential role of the risk profile?proper risk management cannot occur without it.*Conservatism?both P50 and P90+ risk assessments are needed.*Making the risk assessment readily expandable?it should ?get smarter? as new knowledge becomes available.Herein lies essential guidance for keeping pipelines safe: Improving risk knowledge, leading to superior risk management, leading to safer pipelines.

Book Synopsis From Brows to Trust by : Zsófia Ruttkay
Download or read book From Brows to Trust written by Zsófia Ruttkay and published by Springer Science & Business Media. This book was released on 2006-02-19 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Embodied conversational agents (ECAs) are autonomous software entities with human-like appearance and communication skills. These agents can take on a number of different roles, for example, as an assistant, tutor, information provider, or customer service agent. They may also simply represent or entertain a user. The precise nature and benefits of different characteristics of ECAs requires careful investigation. Questions range from the function of an eyebrow raise to mechanisms for assessing and improving ECA trustworthiness. This book will help experts and designers in the specification and development of applications incorporating ECAs. Part 1 provides guidelines for evaluation methodologies and the identification of design and evaluation parameters. Part 2 demonstrates the importance of considering the user's perspective and interaction experience. Part 3 addresses issues in fine-tuning design parameters of ECAs and verifying the perceived effect. Finally, in Part 4 lessons learned from a number of application case studies are presented. The book is intended for both ECA researchers in academia and industry, and developers and designers interested in applying the technology.
