  Statistical Physics of Fracture, Friction and Earthquake - by Hikaru Kawamura

Statistical Physics of Fracture, Friction and Earthquake

Author: Hikaru Kawamura | Size: 2 MB | Format: PDF | Quality: Original preprint | Publisher: Earthquake Research Institute, University of Tokyo, Japan | pages: 52

We review the present status of our research and understanding regarding the dynamics and the statistical properties of earthquakes, mainly from a statistical physical viewpoint. Emphasis is put both on the physics of friction and fracture, which provides a “microscopic” basis of our
understanding of an earthquake instability, and on the statistical physical modelling of earth-quakes, which provides “macroscopic” aspects of such phenomena. Recent numerical results on several representative models are reviewed, with attention to both their “critical” and “characteristic” properties. We highlight some of relevant notions and related issues, including the origin of power-laws often observed in statistical properties of earthquakes, apparently contrasting features
of characteristic earthquakes or asperities, the nature of precursory phenomena and nucleation processes, the origin of slow earthquakes, etc.

  Austroads Guide to Traffic Management Part 3: Traffic Studies and Analysis
Posted by: fuchiguis - 02-18-2012, 02:55 PM - Forum: Archive - No Replies

Part 3 outlines the importance of traffic data and its analysis for the purpose of traffic management and traffic control. It serves as a means to ensure some degree of consistency in conducting traffic studies and surveys. It provides guidance on the different types of traffic studies and surveys that can beundertaken, their use and application, and methods for traffic data collection and analysis. Part 3 covers applications of the theory presented in Part 2 (Austroads 2008a), and provides guidance on traffic analysis for uninterrupted and interrupted flow facilities and for various types of intersections. It outlines sound methods of analysis for effective traffic management, design and control.

  Corrosion of Polymers and Elastomers, 2nd Ed
Posted by: Dell_Brett - 02-18-2012, 09:35 AM - Forum: Other Materials (Wood, Brick, etc.) - Replies (1)

Corrosion of Polymers and Elastomers, 2nd Ed

Author: Philip A. Schweitzer P.E | Size: 1,8 MB | Format: PDF | Quality: Scanner | Publisher: CRC Press | Year: 2006 | pages: 596 | ISBN: 0849382459

[Image: 82079357771115125233.jpg]

[Image: info.png]

Corrosion of Polymers and Elastomers provides a detailed examination of the corrosive effects of thermoplastic polymers, thermoset polymers, and elastomeric materials. The book is perfectly suited for specialists interested in the corrosion resistance and mechanisms of these materials.
Following a general introduction to the composition, properties, and applications of polymers, the book focuses on the effects of chemical corrosion caused by changes in temperature, moisture, and other corrodents. Organized by material type, the chapters cover each material's ability to withstand sun, weather, and ozone as well as its chemical resistance and typical applications. The book also includes compatibility tables for each of the materials and compares the corrosion resistance of selected elastomers.

System Dynamics, 2nd Edition >> By William J Palm III, University of Rhode Island

Author: William J Palm III, University of Rhode Island | Size: zip 9.11 MB | Format: PDF | Quality: Original preprint | Publisher: McGraw-Hill Science/Engineering/Math; 2 edition | Year: ©2010 | pages: 900 | ISBN: ISBN-13 9780073529271 ; MHID 0073529273

A. Description

System Dynamics includes the strongest treatment of computational software and system simulation of any available text, with its early introduction of MATLAB® and Simulink®. The text's extensive coverage also includes discussion of the root locus and frequency response plots, among other methods for assessing system behavior in the time and frequency domains as well as topics such as function discovery, parameter estimation, and system identification techniques, motor performance evaluation, and system dynamics in everyday life.

B. Table of Contents

1 Introduction
2 Modeling of Rigid-Body Mechanical Systems
3 Solution Methods for Dynamic Models
4 Spring and Damper Elements in Mechanical Systems
5 State-Variable Models and Simulation Methods
6 Electrical and Electromechanical Systems
7 Fluid and Thermal Systems
8 System Analysis in the Frequency Domain
9 Transient Response and Block Diagram Models
10 Introduction to Feedback Control Systems
11 Control System Design and the Root Locus Plot
12 Compensator Design and the Bode Plot
13 Vibration Applications
Appendices
Guide to Selected MATLAB Commands and Functions
Fourier Series
Introduction to MATLAB (on the website)
Numerical Methods (on the website)

C. New Features

The dynamics review in Chapter 2 and the introduction to electrical systems in Chapter 6 have been edited for a more concise presentation of the material.

Block diagrams are now presented in Chapter 9 to be closer to their applications in control system analysis. The material in Chapter 5 dealing with transfer functions and state variable methods has been reorganized to better delineate the advantages of each method.

Introduction to MATLAB®, offered on the text website, provides readers with a practical, concise guide to the program.

The former Chapter 11 has been split into two chapters to focus more concisely on PID control system design issues (new Chapter 11) and compensator design (new Chapter 12).

The final chapter (Vibration Applications) now includes coverage of active vibration control systems and nonlinear vibration.

Dear All,

Up to now, we haven't seen any medicine for ESTEEM8. Is that really uncrackable as they claimed? Or someone is working on it already?
