Product Description:
Modern seismology is a relatively new science; most current ideas originated no earlier than the latter half of the nineteenth century. The focus of this book is on seismological concepts, how they originated and how they form our modern understanding of the science. A history of seismology falls naturally into four periods: a largely mythological period previous to the 1755 Lisbon earthquake; a period of direct observation from then to the development of seismometers in the late 19th century; a period during which study of seismic arrival times were used to outline the structure of the earth's interior extending the 1960s; the modern era in which all aspects of seismic waves are used in combination with trial models and computers to elucidate details of the earthquake process. This history attempts to show how modern ideas grew from simple beginnings. Ideas are rarely new, and their first presentations are often neglected until someone is able to present the evidence for their correctness convincingly. Much care has been used to give the earliest sources of ideas and to reference the basic papers on all aspects of earthquake seismology to help investigators find such references in tracing the roots of their own work.

I am writing through this forum because the original thread has been closed and this is the forum that we could raise any issue and I think, not run afoul of the rules. I read with dismay the muddle that was made of the BennyK case. This is one of the indications of the awful things that are happening in this association. When a member of a clique felt that he or whomever he feels sympathy for is piqued, that clique goes on the rampage/offensive and call for the head of the so perceived enemy to be hung on the APPIA way. This forum should not be the exclusive personal property of any one or group of people. People are here today and others are inching to come in because there are mixes of people here. There are people who also work, despite their hard schedule to keep the forum alive. So we are supposed to be humans and remember that if we are but to look on while any of us succeeds in pushing most people out of this forum, I do not think that people will have anything to lose leaving it or missing it. How can we explain a situation whereby a moderator bans a member of the association while the other members of the admin are not aware of it? And one of the reasons for banning that person was that he used a name that was similar to the self acclaimed Re, emperor pharos of Egypt. Yet he was able to come up and say that he even took pre-emptive and premeditated action before the actual banning of the person from the forum. Incredible. This is the only civilized place that I am seeing such a thing happening. And the person that was beaten was also told that he should not cry. I think that BennyP is becoming an enigma. I, as a person, will not like to belong to an association that a person in this century, despite our levels in the society herd us around and runs the place as a fiefdom. Whatever that guy (is he called BennyK) did, he deserves being given the benefit of due process. I do not think that threatening people with ban etc is the best approach to making people toe the line or dance to a perceived tone. Like I had always said and like many people will not be in agreement with me (as they will rise to defend him and call for heads to be served on hot bowls of pepper soup), we have to drive softly. It is people that make up this association. Do not drive away all the people in this association that do not appeal to you.
Regards
Teddy

The unique and practical Materials Handbook (second edition) provides quick and easy access to data on the physical and chemical properties of all classes of materials. The second edition has been much expanded to include whole new families of materials while many of the existing families are broadened and refined with new material and up-to-date information. Particular emphasis is placed on the properties of common industrial materials in each class. After a chapter introducing some general properties of materials, materials are classified as follows:
• ferrous metals and their alloys;
• nonferrous metals;
• semiconductors and superconductors;
• magnetic materials;
• insulators and dielectrics;
• miscellaneous electrical materials;
• ceramics, refractories and glasses;
• polymers and elastomers;
• minerals, ores and gemstones;
• rocks and meteorites;
• soils and fertilizers;
• cements, concrete, building stones and construction materials;
• timbers and woods;
• fuels, propellants and explosives;
• composite materials;
• gases;
• liquids.
Detailed appendices provide additional information on subjects as diverse as crystallography, natural radioactivity and economic data for industrial materials. Specific further reading sections and a general bibliography round out this comprehensive guide. The index and tabular format of the book make light work of extracting what the reader needs to know from the wealth of factual information within these covers.

1.About this book
Mankind has a fascination with measurement. Down the centuries we have produced a plethora of incompatible and duplicatory systems for measuring everything from the width of an Egyptian pyramid to the concentration of radioactivity near a nuclear reactor and the value of the fine structure constant. With the introduction first of the metric system and of its successor the Système International d'Unités (SI), the scientific community has established a standard method of measurement based on only seven core units.
The Encyclopaedia of Scientific Units, Weights and Measures converts the huge variety of units from all over the world in every period of recorded history into units of the SI. Featuring:
- An A - Z of conversion tables for over 10,000 units of measurements.
- Tables of the fundamental constants of nature with their units.
- Listings of professional societies, and national standardization bodies for easy reference.
- An extensive bibliography detailing further reading on the multifarious aspects of measurement and its units.
This huge work is simply a "must have" for any reference library frequented by scientists of any discipline or by those with historical interests in units of measurement such as archaeologists.

Nonlinear Dynamics: Between Linear and Impact Limits

Copy of Preface:
The main objective of this book is to introduce a unified physical basis for analyses of vibrations with essentially unharmonic, non-smooth or may be discontinuous time shapes. It is known that possible transitions to nonsmooth limits can make investigations especially difficult. This is due to the fact that the dynamic methods were originally developed within the paradigm of smooth motions based on the classical theory of differential equations.
From the physical standpoint, these represent low-energy approaches to modeling dynamical systems. Although the impact dynamics has also quite a long pre-history, any kind of non-smooth behavior is often viewed as an exemption rather than a rule. Similarly, the classical theory of differential equations usually avoids non-differentiable and discontinuous functions. To-date, however, many theoretical and applied areas cover high-energy phenomena accompanied by strongly non-linear spatio-temporal behaviors making the classical smooth methods inefficient in many cases. For instance, such phenomena occur when dealing with dynamical systems under constraint conditions, friction-induced vibrations, structural damages due to cracks, liquid sloshing impacts, and numerous problems of nonlinear physics. Similarly to the wellknown analogy between mechanical and electrical harmonic oscillators, some electronic instruments include so-called Schmitt trigger circuits generating nonsmooth signals whose temporal shapes resemble mechanical vibro-impact processes. In many such cases, it is still possible to adapt different smooth methods of the dynamic analyses through strongly non-linear algebraic manipulations with state vectors or by splitting the phase space into multiple domains based on the system specifics. As a result, the related formulations are often reduced to discrete mappings in a wide range of the dynamics from periodic to atochastic. Possible alternatives to such approaches can be built on generating models developing essentially nonlinear/unharmonic behaviors as their inherent properties. Such models must be general and simple enough in order to play the role of physical basis. As shown in this book, new generating systems can be found by intentionally imposing the ‘worst case scenario’ on conventional methods in anticipation that failure of one asymptotic may point to its complementary counterpart. However, the related mathematical formalizations are seldom straightforward and require new principles. For instance, the tool developed here employs nonsmooth (impact) systems as a basis to describing not only impact but also smooth or even linear dynamics. This is built on the idea of non-smooth time substitutions/transformations (NSTT) proposed originally for strongly nonlinear but still smooth models.
On the author’s view, the methodological role of NSTT is to reveal explicit links between impact dynamics and hyperbolic algebras analogously to the link between harmonic vibrations and conventional complex analyses. In particular, this book gives the first systematic description for NSTT and related analytical and numerical algorithms. The text focuses on methodologies and discussions of their physical and mathematical basics. Detailed applications are mostly excluded from this book, however, necessary references on journal publications are provided.
Short description:
Nonlinear Dynamics represents a wide interdisciplinary area of research dealing with a variety of “unusual” physical phenomena by means of nonlinear differential equations, discrete mappings, and related mathematical algorithms. However, with no real substitute for the linear superposition principle, the methods of Nonlinear Dynamics appeared to be very diverse, individual and technically complicated. This book makes an attempt to find a common ground for nonlinear dynamic analyses based on the existence of strongly nonlinear but quite simple counterparts to the linear models and tools. It is shown that, since the subgroup of rotations, harmonic oscillators, and the conventional complex analysis generate linear and weakly nonlinear approaches, then translations and reflections, impact oscillators, and hyperbolic (Clifford’s) algebras must give rise to some “quasi impact” methodology. Such strongly nonlinear methods are developed in several chapters of this book based on the idea of non-smooth time substitutions. Although most of the illustrations are based on mechanical oscillators, the area of applications may include also electric, electro-mechanical, electrochemical and other physical models generating strongly anharmonic temporal signals or spatial distributions. Possible applications to periodic elastic structures with non-smooth or discontinuous characteristics are outlined in the final chapter of the book.

Concrete and Clay Roof Tile Installation Manual for Moderate Climate Regions
[img][/img]
The Roof Tile Institute, formerly the National Tile Roofing Manufacturers Association (NTRMA), has realized the need to establish an industry based manual that would cover the installation of concrete and clay tile as a roof assembly in the moderate climate regions of North America. The Roof Tile Institute in partnership with the Western States Roofing Contractors Association (WSRCA) assembled a task group to develop a single manual that would provide a representation of the best installation practices, industry standards, and code requirements. These recommendations have provided successful installations of roof tile which endured the test of time.
These recommendations are meant for areas with moderate climates that may experience occasional storms. In locations where the January mean temperature is 30 deg. F (-1 deg C) or less or where ice damming can occur, the RTI /WSRCA suggests reference to the Concrete and Clay Tile Roof Design Criteria Manual for Cold and Snow Regions. While generally considered the minimum standard, proper adherence to these recommendations and attention to detail and workmanship provide a functional roof in all but the most severe conditions. Local building officials should be consulted for engineering criteria or other special requirements.
This manual provides the minimum design recommendations with optional upgrades for the installation of underlayment, flashings, fastening and related measures to provide a weather resistant roofing assembly for concrete and clay tile.
