Book Description
Mformation about a material can be gathered from its interaction with electromagnetic waves. The information may be stored in the amplitude, the phase, the polarisation, the angular distribution of energy transportation or the spectral characteristics. When re trieved from the wave, certain material properties may thus be determined indirectly. Compared on the one hand to direct material analysis, an indirect method requires calibration and is prone to interference from undesired sources. On the other hand, however, it permits the determination of features inaccessible by direct methods, such as non-destructive material interrogation, high measurement speed, or deep penetration depth. However, being a physical method, the use of electromagnetic waves is still handicapped by the lack of acceptance by many chemists, who are used to applying direct approaches. Historically, the first application of electromagnetic wave interaction with mat ter involved measurement of amplitude changes at a single frequency caused by material properties, and it is still used today by some systems. This approach was soon supplemented by single frequency phase measurements, in order to avoid distortions through amplitude instabilities or parasitic reflections. Such single pa rameter measurements of course require dependence only on one variable in the measured process and sufficient stability of all other ancillary conditions. If that is not the case, the single parameter measurement fails.

Book Description
The idea of this book was born due to the rapid increase of the interest in excellence of agricultural production in the aspect of both – the quality of raw material for food production as well as in the aspect of environment protection. Agrophysics is a field of science that focuses on the quality of agriculture as a whole i.e. the interaction between human and environment, especially the interaction between soil, plant, atmosphere and machine. Physics with its laws, principles and rules is a good tool for description of the interactions, as well as of the results of these interactions. Some aspects of chemistry, biology and other fields of science are also taken under consideration. This interdisciplinary approach can result in holistic description of processes which should lead to improvement of the efficiency of obtaining the raw materials to ensure a sufficient amount of food, safe for human health. This book could be regarded as the contribution to this description. The reader can find some basic as well, as more particular aspects of the contemporary agriculture, starting with the soil characteristics and treatment, plant growth and agricultural products’ properties and processing.

Book Description
Electromagnetic moisture measurement technologies have proven to be valuable tools in diverse applications. This monograph covers basic aspects of nondestructive electromagnetic methods of water content determination and relates to the associated highly multidisciplinary field of research and development. It also presents a comprehensive selection of relevant field-tested methods and instruments. The fundamentals of electromagnetic field interactions with dipolar materials are briefly discussed, with special attention towards the dielectric properties of water and aqueous solutions. A tutorial and overview of electromagnetic measurement methods is presented, including dielectric spectroscopy in broad frequency and time domains, as well as dielectric imaging techniques. This review is complemented by a demonstration of successful real-world implementations for the moisture determination of soils, snow, buildings and building materials, food and agricultural goods, as well as various industrial products. The text is completed by a guide concerning the use of reference liquids for the calibration of sensors and instrumentation and by a bibliography of more than 850 references. The monograph is useful as a reference book for researchers and engineers and as a textbook for upper-level students interested in the water content determination of materials.

Book Description
The discipline of instrumentation has grown appreciably in recent years because of advances in sensor technology and in the interconnectivity of sensors, computers and control systems. This 4e of the Instrumentation Reference Book embraces the equipment and systems used to detect, track and store data related to physical, chemical, electrical, thermal and mechanical properties of materials, systems and operations. While traditionally a key area within mechanical and industrial engineering, understanding this greater and more complex use of sensing and monitoring controls and systems is essential for a wide variety of engineering areas--from manufacturing to chemical processing to aerospace operations to even the everyday automobile. In turn, this has meant that the automation of manufacturing, process industries, and even building and infrastructure construction has been improved dramatically. And now with remote wireless instrumentation, heretofore inaccessible or widely dispersed operations and procedures can be automatically monitored and controlled. This already well-established reference work will reflect these dramatic changes with improved and expanded coverage of the traditional domains of instrumentation as well as the cutting-edge areas of digital integration of complex sensor/control systems. - Thoroughly revised, with up-to-date coverage of wireless sensors and systems, as well as nanotechnologies role in the evolution of sensor technology - Latest information on new sensor equipment, new measurement standards, and new software for embedded control systems, networking and automated control - Three entirely new sections on Controllers, Actuators and Final Control Elements; Manufacturing Execution Systems; and Automation Knowledge Base - Up-dated and expanded references and critical standards
