The tuned mass damper is one of the classic dynamic vibration absorbers with effective devices for energy dissipation and vibration reduction. The electromagnetically tuned mass damper system is extensively used for vibration reduction in engineering. A better understanding of the nonlinear dynamics of the electromagnetically tuned mass damper system is very important to optimize the parameters of such systems for vibration reduction. However, until now, one cannot fully understand complex periodic motions in such a nonlinear, electromagnetically tuned mass damper system. In this book, the semi-analytical solutions of periodic motions are presented through period-1, period-3, period-9, and period-12 motions. The corresponding stability and bifurcations of periodic motions are determined. The frequency-amplitude characteristics for bifurcation routes of such higher-order periodic motions are presented. This book helps people better understand the dynamical behaviors of an electromagnetically tuned mass damper system for the new development and design of vibration reduction and energy harvesting systems.

The world's population is steadily increasing and with it is an increasing demand for freshwater, for both drinking and irrigation. In many areas of the world, particularly in arid regions, there are limited freshwater sources such as rivers and groundwater, so desalination is being increasingly used to produce freshwater to satisfy both requirements. Although desalination is sometimes carried out on brackish waters and highly saline well waters, most desalination plants generate fresh water from seawater with a daily production that reached 95 million m3/day in 2019. Drs. Francis and Meroufel have been active in all types of desalination plants for many years, either solving corrosion problems, or, less often, preventing them from happening. There are very few publications that discuss the specific corrosion problems in desalination plants, and there are none written with the plant engineer in mind. Plant engineers often do not have an in-depth knowledge of corrosion, and because of this, they need help with day-to-day problems that may involve corrosion. Modern desalination plants are often designed with a 40-year lifespan, so it is important that plant engineers know how to tackle corrosion problems to maintain water production without shutdowns or, in extreme cases, shortening plant life.This book was conceived as being a helpful guide that can sit on an engineer's desk, and which will give advice not just on diagnosing corrosion failures, but on how to monitor the plant's resistance to corrosion by inspection and monitoring.

Microhistory is a technique that has been used effectively by writers of both fiction and nonfiction. It enables the author to cut through the complexities of large swaths of history by focusing on a particular time and place. Microhistories are particularly useful in historical study when a subfield has recently arisen and there are not yet enough monographic studies from which to draw general patterns. This microhistory focuses on a single year (1920) across the United States, with the goal of understanding the various roles of information in this society. It gives greater emphasis to the informational aspects of traditional historical topics such as farming, government bureaucracy, the Spanish flu pandemic, and Prohibition; and it gives greater attention to information-rich topics such as libraries and museums, schools and colleges, the financial services and office machinery industries, scientific research institutions, and management consultancies.

This book covers the new field of straintronics, using strain switched nanomagnets for extremely energy-efficient computing, information processing, communication, and signal generation. Based on well-established CMOS technology, traditional electronics have two significant shortcomings: excessive energy dissipation and volatility, which is the inability to retain information after power has been switched off. Straintronics is more energy-efficient and non-volatile (but also more error-prone), allowing it to eclipse traditional electronics in niche areas that are increasingly attracting attention, such as image processing and probabilistic computing, computer vision, machine learning, neuromorphic networks, probabilistic computing, and belief networks. Magnetic Straintronics: An Energy-Efficient Hardware Paradigm for Digital and Analog Information Processing introduces straintronics and the technology's myriad applications for researchers, engineers, and scientists in electrical engineering, physics, and computer engineering.

The effects of additives on the flow characteristics of drilling muds used in various drilling operations, including oil and gas wells, must be better quantified. In this study, acrylamide polymer was used to modify water-based bentonite mud to reduce the yield point and maximum shear stress produced by the mud during the drilling operation. The bentonite content in the drilling mud was varied up to 6% (by weight). Based on the X-ray diffraction (XRD) analyses, the major constituents of bentonite were montmorillonite (MMT, (Na,Ca)0.33(Al,Mg)2(Si4O10)(OH)2·nH2O), feldspar (Albite, NaAlSi3O8), kaolinite (Al2Si2O5(OH4)), Beidellite ((Na,Ca0.5)0.3Al2((Si,Al)4O10)(OH)2·nH2O) and quartz (SiO2). Bentonite was modified using a water-soluble polymer solution before being used in the drilling mud. The rheological properties of bentonite were characterized from a very low strain rate to a relatively high strain rate to determine the nonlinear behavior of the shear-thinning drilling mud. The polymer modification reduced the yield point by 26-66% based on the bentonite content in the drilling mud.

Angriffe aus den eigenen Reihen durch sogenannte Innentäter sind für Unternehmen nur schwer zu erkennen. Unter Innentätern versteht man Personen, die in Unternehmen oder Organisationen vorsätzlich dolose Handlungen vornehmen. Ihnen fällt es aufgrund ihres Wissens über Interna leichter, etablierte Schutzmaßnahmen zu überwinden. Unternehmensinhaber trifft im Rahmen des mehrdeutigen Begriffs unternehmerischer Compliance auch eine Pflicht, in ihrem Betrieb für regelgetreues Verhalten der Beschäftigten zu sorgen. Es besteht insofern ein Spannungsverhältnis zwischen dem Recht auf informationelle Selbstbestimmung des Beschäftigten, welches durch das Datenschutzrecht geschützt wird, und der Pflicht des Arbeitgebers, in seinem Unternehmen für rechtskonformes Verhalten zu sorgen. Gegenstand des Buchs ist daher die Frage, welche Konsequenzen die Datenschutz-Grundverordnung sowie die Gesetzgebung auf nationalstaatlicher Ebene für den Beschäftigtendatenschutz im Allgemeinen sowie für die Umsetzung der neuen Anforderungen bei unternehmensinternen Compliance-Maßnahmen hat.
