A calibration procedure is generally an operation to determine a relationship between an output and an input of an instrument or an essential value of a measuring object in a measuring system. In other words, calibration is a comparison of a measuring device against a standard instrument of higher accuracy. In measuring fields, the calibration is clearly confirmed in the traceability system. The traceability is defined as the property of a result of a measurement whereby it can be related to strictly defined standards, in general, nationally or internationally recognised, through an unbroken chain of comparisons. Namely, all calibrations are strictly defined to be performed traceable to a nationally or internationally recognised standard in a measuring field. The term "calibration" is used not only in measuring fields but also in meteorology, chemistry and economics. Also, in these fields the term "calibration" is used as an operation to adjust and/or compensate a measuring system, and a method for accurately determining the relational expression between an input/output of an instrument using suitable standards, for example, an appropriate global optimisation method. However, compared to the measuring field, in these other research areas the calibration seems to be defined in a less systematic way, possibly due to the different nature of these disciplines. In this volume, calibration is defined in the above-mentioned broad sense of the term, and the topics for discussion are broad and abundant. The standard of calibration as a method which is confirmed systematically in the measurement field has been developing also in other disciplines. They have many research issues, but constitute a promising area of research.

Supervisory control and data acquisition (SCADA) technology has evolved over the past 30 years as a method of monitoring and controlling large processes. This newly revised reference book offers overviews of SCADA's component technologies, as well as details necessary to understand the big picture. SCADA processes cover areas that may be measured in the thousands of square miles, and have dimensions that may be hundreds, occasionally thousands, of miles long. Now a mature technology, SCADA includes, but is not limited to, software packages that can be incorporated in a larger system. After completing its 14 self-study units, readers should be conversant with SCADA nomenclature and architecture, understand the basic technology of the system's building blocks, understand its limitations, understand how it can benefit particular operations, and have a basis for selecting appropriate SCADA technologies for their operational requirements.

This second edition of a unique text/reference identifies the appearance attributes of objects and the methods available for measuring them, bringing together much material not previously organized for ready reference. The primary premise here is that ``object appearance'' involves not only color, but such attributes as gloss, luster, and translucency. The first part of the book, concerned with nature of appearance, draws from the fields of physiology and psychology and considers the eye-brain combination and the way it receives and interprets light signals. This is followed by a consideration of the optical properties of objects from the physical standpoint. The second part of the book deals with the numerical scales used to measure object appearance. The discussion here draws on psychophysics in describing the uses of physical techniques to give numbers having psychological significance. The third part of the book covers instruments for the measurement of the attributes of object appearance, their principles of design, and a survey of the major ones in use. The final chapter discusses specific applications of appearance measurement. Includes appendixes and a glossary.

Industry wastewater is a major contributor to environmental pollution with chemicals such as dyes, acids, fungicides, and more creating a threat to the environment. Nanocomposites of heterogeneous photocatalysis can be used to cure such problems due to its efficiency and ease of use, as well as the fact that it turns toxic chemicals completely to carbon dioxide and inorganic acids. With toxic chemicals posing a tremendous threat to ecological wellbeing and human health, it is integral that a variety of nanocomposites are studied for their use in the degradation of toxic and hazardous chemicals. Innovative Nanocomposites for the Remediation and Decontamination of Wastewater describes the synthesis of nanomaterials and its application for the protection of the environment. It presents studies on the photodegradation of the various toxic and hazardous chemicals by different nanocomposites, as well as the decontamination of bodies of water through the use of various nanocomposites. Covering topics such as dye degradation, novel biomaterials, and structural modification, this premier reference source is a vital resource for environmental scientists, construction managers, compliance officers, biochemists, biophysicists, conservation scientists, hydrologists, microbiologists, libraries, students and educators of higher education, researchers, and academicians.

This book provides practical, comprehensive knowledge on how to use the advances in analytical measurements and basic and advanced control to improve batch profiles and endpoint consistency. The consequential integration of measurements, models, and controls into a digital twin with recently developed blocks to provide profiles and predict endpoints enables: Developing dynamic models from trend charts that are used for experiment design, diagnosing the sources of limitations and inconsistences, and developing and testing solutions 500 times real time without interfering with existing plant operation. Comprehensive views of basic process control with the possibilities of model predictive control to control and optimize batch profiles by non-intrusive development and confirmation. The ability to determine how to maximize the performance of bioreactors, which are often the bottleneck and the key to product quality and consistency, without tests or trials in the actual plant. The resulting improvements in batch cycle time and consistency can be designed, tested, quantified, and confirmed; and operators can be trained independently of actual plant operation. The benefit from the elimination of a bad batch—particularly for new biologics—is potentially worth ten or more million dollars.
