- The state-of-the-art in seismic evaluation & retrofitting is presented

- The subject is of prime practical importance internationally
In the past, facilities considered to be at the end of their useful life were demolished and replaced with new ones that better met the functional requirements of modern society, including new safety standards. Humankind has recently recognised the threats to the environment and to our limited natural resources due to our relentless determination to destroy the old and build anew. With the awareness of these constraints and the emphasis on sustainability, in future the majority of old structures will be retrofitted to extend their service life as long as feasible. In keeping with this new approach, the EU’s Construction Products Regulation 305/2011, which is the basis of the Eurocodes, included the sustainable use of resources as an "Essential Requirement" for construction. So, the forthcoming second generation of EN-Eurocodes will cover not only the design of new structures, but the rehabilitation of existing ones as well.
Most of the existing building stock and civil infrastructures are seismically deficient. When the time comes for a decision to prolong their service life with the help of structural and architectural upgrading, seismic retrofitting may be needed. Further, it is often decided to enhance the earthquake resistance of facilities that still meet their functional requirements and fulfil their purpose, if they are not earthquake-safe. In order to decide how badly a structure needs seismic upgrading or to prioritise it in a population of structures, a seismic evaluation is needed, which also serves as a guide for the extent and type of strengthening. Seismic codes do not sufficiently cover the delicate phase of seismic evaluation nor the many potential technical options for seismic upgrading; therefore research is on-going and the state-of-the-art is constantly evolving. All the more so as seismic evaluation and rehabilitation demand considerable expertise, to make best use of the available safety margins in the existing structure, to adapt the engineering capabilities and techniques at hand to the particularities of a project, to minimise disruption of use, etc. Further, as old structures are very diverse in terms of their materials and layout, seismic retrofitting does not lend itself to straightforward codified procedures or cook-book approaches. As such, seismic evaluation and rehabilitation need the best that the current state-of-the-art can offer on all aspects of earthquake engineering. This volume serves this need, as it gathers the most recent research of top seismic experts from around the world on seismic evaluation, retrofitting and closely related subjects.

Geostatistics for Natural Resources Characterization: Part 1
Nato ASI Science Series C, Vol. 122
Editors: G. Verly, M. David, A.G. Journel, A. Marechal | Size: 20 MB | Format:PDF | Quality:Scanner | Publisher: Springer | Year: 1984 | Pages: 585 | ISBN: 9789400936997, 9789401081573
Since October 1975 and the first NATO ASl "Geostat - Roma 1975", there has not been an advanced workshop on geostatistics where experts from throughout the world could meet, teach and debate without the pressure of an ordinary professional conference. This second NATO ASI "Geostat - Tahoe 1983" was intended as a high-level teaching activity yet opened to all new ideas and contributions to the discipline of geostatistics. It was expected that the institute would bridge the gap since "Geostat - Roma 1975" and establish the state of the art of the discipline as of 1983.
"Geostat - Tahoe 1983" fulfilled all expectations. The institute, held in September 1983 at the Stanford Sierra Lodge near Lake Tahoe, California, was attended by all major players in the field, representing evenly the academy and the industry of 23 different countries. Twelve guest lecturers were backed by some 50 original contributions. Particularly important for the future was the active participation of graduate students, glvlng evidence of the dynamism of a still very young discipline.
Applications of geostatistics are no longer limited to the mining industry, and the original scope of the ASI had to be widened to witness the progress made in such fields as hydrology, soil sciences, pollution control and geotechnical engineering. Also important was the cross-fertilization from oiher statistical branches such as spectral analysis and robust statistics.
The NATO ASI "Geostat - Tahoe 1983" will be remembered as a major milestone in the development of the discipline. I invite all of you who did not make it to the ASI to dive into these proceedings and share a bit of the excitement that pervaded this summer's end at Lake Tahoe.

Drawing on their decades of teaching experience, William Briggs and Lyle Cochran have created a calculus text that carries the teacher’s voice beyond the classroom. That voice–evident in the narrative, the figures, and the questions interspersed in the narrative–is a master teacher leading readers to deeper levels of understanding. The authors appeal to readers’ geometric intuition to introduce fundamental concepts and lay the foundation for the more rigorous development that follows. Comprehensive exercise sets have received praise for their creativity, quality, and scope.

The Thermal Spraying manual published by the American Welding Society presents the considerations required to appraise any application of thermal spraying. This manual also surveys the basic methods that can be used and the equipment and consumables involved in thermal spraying.
Although thermal spraying has been used since the early part of the twentieth century, many of the first applications were concerned mainly with reclamation. Since 1960, there has been a dramatic expansion in the number and diversity of thermal spray applications. Technological advances and material developments have resulted in a multitude of new and potential applications. The present range and scope of the processes and uses can only be indicated in this manual.
The American Welding Society Committee on Thermal Spraying has prepared this first edition as a guide to the equipment and consumables available, and as a reference for selecting the process suitable for a particular application. The reader can acquire knowledge of the thermal spray processes and technology to investigate potential uses. Emphasis is placed on practical shop and field procedures, including factual, supportive data.
