Rotary Theory of the Magnetic Field
ISBN: 9783659780981 / Angielski / Miękka / 148 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This monograph is dedicated to a new macro-theory of electromagnetics and to a group of fundamental issues, related to that theory. This work is an attempt to break the classic approach for introducing the basic concepts, quantities and laws, giving the foundation for the perception of different electromagnetic effects and phenomena. A model of the magnetic field is proposed, accompanied by the use of new quantities and concepts, through which the existing electromagnetic laws and quantities can be perceived in a completely new and natural way in a whole, which the classic theory does not...

Laser ultrasonics with a fiber optic sensor
ISBN: 9783659660733 / Angielski / Miękka / 180 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Conventional ultrasound testing technique usually employs a piezoelectric transducer to both generate and detect ultrasonic waves to perform non-destructive inspection. However, this type of transducer presents some drawbacks as: requirement of a coupling medium, high temperatures are not supported, narrow bandwidth, low spatial resolution, load the sample, and is hard to be used in complex geometries. In contrast, the laser ultrasonics technique can overcome these problems by taking advantage of the weightless non-contact nature of light, and both generation and detection of ultrasonic waves...
