• This book examines pedestrian shoe-floor slip resistance from an engineering standpoint in order to better understand friction and wear behavior. This analysis includes an extensive investigation into the surface properties of shoes and flow, and the measurement of dynamic friction and other mechanical and physical aspects of shoe-floor tribology. Lastly, the book proposes a measurement concept for the identification and classification of operational floor surfaces under a range of different conditions.Novel techniques and methods are proposed that can improve the reliability of slip resistance assessments. The current state of knowledge is critically examined and discussed from a tribological perspective, including aspects like friction, wear, lubrication and the mechanical behavior of shoes, floors and their wider environment. Further, the book reports on extensive experimental investigations into the topographical characteristics of shoe and floor surfaces and how they affect slip resistance. Slips resulting in pedestrian falls are a major cause of injuries and deaths for all age groups. This important book provides essential insights for researchers, practicing engineers and public safety officials wishing to learn about how the risk of pedestrian slips can be assessed and understood.

  • Qu'est-ce qu'un objet ancien de nos jours ? À partir de quelle période peut-on considérer un objet comme objet ancien ? C'est un objet toujours vivant mais qui demande une autre définition que celle d'outil ou d'objet décoratif. L'objet ancien porte l'empreinte de la vie d'un autre temps. Les traces visibles et invisibles sur l'objet ancien témoignent de la présence immortelle de la vie et caractérisent l'objet. Comment reconnaître cette vie et définir l'essence de cet objet qui porte la trace du temps et de la main de l'homme ? Ces questions invitent à rechercher les objets anciens apparus dans les oeuvres d'artistes contemporains en redéfinissant leur forme et leur essence au-delà de leur matérialité. Ainsi compris, l'objet ancien définit une notion de l'art contemporain et n'est plus un simple matériau de l'art.

  • This book contains selected papers based on talks given at the "Representation Theory, Number Theory, and Invariant Theory" conference held at Yale University from June 1 to June 5, 2015. The meeting and this resulting volume are in honor of Professor Roger Howe, on the occasion of his 70th birthday, whose work and insights have been deeply influential in the development of these fields. The speakers who contributed to this work include Roger Howe's doctoral students, Roger Howe himself, and other world renowned mathematicians. Topics covered include automorphic forms, invariant theory, representation theory of reductive groups over local fields, and related subjects.

  • This book examines relationships between climate-hydrological changes and other phenomena including land use and natural disasters during the Holocene and recent past. In particular, periods of rapid climatic shifts such as global warming and global cooling are examined through paleohydrological and other studies of various lake-catchment systems in East Asia, from Mongolia in the north to Taiwan in the south. A number of different research techniques are used in the work presented here, including sediment analysis and optically stimulated luminescence dating and the reader learns how the lake-catchment system functions as a "proxy observatory" for past and present environmental monitoring. The lake catchments studied by the authors of this volume are under similar climatic conditions, i.e., under the East Asia monsoon, with some systematic difference in climatic factors. Both proxy and observation data are available for the surrounding countries' provisions against natural disasters that are related to climate-hydrological events and readers will see how present instrumental observation data can be connected to past proxy data (sediment information) in the system.

  • This book analyzes state-owned enterprises (SOEs), which are still significant players in many Asian economies. They provide essential public services, build and operate key infrastructure, and are often reservoirs of public employment. Their characteristics and inherent competitive advantages as publicly owned enterprises allow them to play these critical roles. Their weaknesses in governance and inefficiencies in incentive structures, however, also often lead to poor performance.

    SOEs must be efficient, transparent, and accountable to level the playing field for private companies, secure the growth of a vibrant private sector, and achieve sustained and inclusive economic growth. This book analyzes the reform of SOEs in Asia, the results of which are mixed.

    The volume concludes that some key conditions generally need to be met for SOE reforms to be successful: national bureaucracies must have the capacity to implement the reforms, and adverse impacts on international trade and investment must be avoided.
