Electro Mechanical Impedance signatures for Timber By Venu Gopal Madhav Annamdas
eBook (PDF): $1.75
Download immediately.
Re-visiting natural disasters like the recent Haiti earthquake (12 Jan 2010) or Katrina (cyclones) reminds the necessity to have better housing infrastructure with robust monitoring systems in USA.... More > Traditionally wood is accepted as excellent rehabilitation material, after any disaster. The key issue which dampens the life of these rehabilitated structure is unnecessary deposits (nails, screws, bolts etc) / damages due to insect attack. Thus, a few health monitoring techniques have emerged in the recent past using smart materials. They are used in various techniques to monitor health of engineering structures. Electromechanical Impedance (EMI) technique is one such technique, which uses PZTs (or MFCs). This is simple yet robust to detect variations in the integrity of structures. In this book, various smart materials are discussed which are relevant to structural health Especially EMI technique to monitor timber is presented.< Less

More > mechanics, vector analysis and rf cicuit design.The full workings and code are made available for the use and adaptation of the reader. Here we walk through examples of using linear algebra and matrices to solve problems like cost estimation, we show how similar techniques are used in electrical theory and circuit design. We show how ballistics can predict the range of a football and the time of travel of a bullet. We see how we can generate 3d transforms of rotation and reflection of objects about general axes and mirrors. We look at the problem of signal rejection in transmission lines and give worked solutions.< Less
