Weapon of Choice - Fighting Gun Violence While Respecting Gun Rights (Hardcover)
Ian Ayres, Fredrick E Vars
How ordinary Americans, frustrated by the legal and political wrangling over the Second Amendment, can fight for reforms that will both respect gun owners' rights and reduce gun violence. Efforts to reduce gun violence in the United States face formidable political and constitutional barriers. Legislation that would ban or broadly restrict firearms runs afoul of the Supreme Court's current interpretation of the Second Amendment. And gun rights advocates have joined a politically savvy firearms industry in a powerful coalition that stymies reform. Ian Ayres and Fredrick Vars suggest a new way forward. We can decrease the number of gun deaths, they argue, by empowering individual citizens to choose common-sense gun reforms for themselves. Rather than ask politicians to impose one-size-fits-all rules, we can harness a libertarian approach-one that respects and expands individual freedom and personal choice-to combat the scourge of gun violence. Ayres and Vars identify ten policies that can be immediately adopted at the state level to reduce the number of gun-related deaths without affecting the rights of gun owners. For example, Donna's Law, a voluntary program whereby individuals can choose to restrict their ability to purchase or possess firearms, can significantly decrease suicide rates. Amending red flag statutes, which allow judges to restrict access to guns when an individual has shown evidence of dangerousness, can give police flexible and effective tools to keep people safe. Encouraging the use of unlawful possession petitions can help communities remove guns from more than a million Americans who are legally disqualified from owning them. By embracing these and other new forms of decentralized gun control, the United States can move past partisan gridlock and save lives now.

Measurement in Science and Civil Engineering (Hardcover)
In order to develop, research, model, or construct it is require to perform measurements on those systems we are interested. The type of measurement will be given by the nature of the object, or the subject under investigation. In science the measurements often pursue to understand very complicated phenomena, inaccessible sometimes to the currents measurement devices or that may need some innovation in the protocols used. Of course it is in science and engineering where most of the innovations manifest primary and then are exported to other fields, for instance the measure devise in high energy experiments carry a lot of new techniques and protocols to improve the characterization of a variety of systems. In a laboratory the conditions to perform a measurement can be controlled to a certain degree, but facing measurement in outside scenarios involves more complex situations. Typically, any construction needs the proper elaboration of it constituents, saying concrete, steel of any other product of pre-manufacturing origin, that requires in every step of its fabrication a control and monitoring, even beyond the factories, the in-situ measure of certain terrains characteristics, tension on rail roads, porosity in the ground and in the structures, all of these depends of meticulous and appropriate measurements using a variety of techniques, very often originated in pure sciences. Students, civil engineers, and materials scientists will find this book to be a good comprehensive resource for learning about the fundamental methods used in those fields to achieve trustworthy measures, focusing on specific examples that are also top research in the area, suitable for the interested reader.
Fundamentals of Hydraulics (Hardcover)
Hydraulics corresponds to a wide variety of fields unified in a marvelous engineering set of models, all of then resting on several basic physical principles and with vast applications. The direct applications go from simple home hydraulic systems, as in our kitchens or bathrooms to the large industrial structures, buildings, factories, all that make modern life possible. The industrial applications are by far the most studied. It is indeed needed to understand the flows on different geometries, and how this flow produces changes in the system, pressure and viscosity, that determines how the fluid is going to behave even in the simplest structure. The complications to compute and make predictions are enormous, it is only with the aid of numerical calculations that some results can be obtained, nevertheless, the control by using valves and several types of pipelines and some other devices that allow us to reproduce the results that we need for control and applications, even when the fluids are in turbulent and complex regimes. The research in this field pursues to understand mostly industrial applications, but some branches are also related to basic science, where the physics is similar, although the equations that rules are different, such as nanofluids, nanosensors devices and nanoparticles motion in a fluid. The aim of this book is to take some practical examples and show the most relevant concepts and methods. We hope it will give a little inside into the physics and techniques involved in the hydraulics engineering.
Control of Quantum Systems (Hardcover)
The control of quantum physical systems refers to those whose behavior is dominated by the laws of quantum mechanics. The effective capabilities of manipulating matter and light at those scales is steadily growing and new experimental and technological possibilities are at reach, the interest in developing systematic theories for controlled quantum mechanical systems is rapidly increasing. The advantage offered by quantum information processes such as in spintronic devices has given to quantum control a new perspective, the ability of employing quantum systems to store, manipulate and retrieve information. It requires an unprecedented degree of control, and further motivates the development of control schemes specifically designed to the quantum mechanical setting. Over the past fifteen years, significant developments have been made in utilizing quantum attributes of light and matter to assume unprecedented control over the dynamics of atomic and molecular systems. This growth reflects a confluence of factors including the better understanding of quantum mechanics as a tool for chemistry and physics, the development of new laser devices increasing our ability to manipulate light, and the recognition that coherent laser light can be used to imprint information on atoms and molecules for practical purposes. In this book we cover some aspects of the basics and controlling of quantum systems using a theoretical and applied approaches, from the very grounds of the theory to some hybrid approaches to quantum control. Hope this book can guide the reader into the deeps of this fascinating field.
Optical Methods for Solid Mechanics (Hardcover)
Solid mechanics is fundamental for civil, aerospace, nuclear, and mechanical engineering, for geology, and for many branches of physics such as materials science. It has specific applications in many other areas, such as understanding the anatomy of living beings, and the design of dental prostheses and surgical implants. One of the most common practical applications of solid mechanics is the Euler-Bernoulli beam equation. Solid mechanics extensively uses tensors to describe stresses, strains, and the relationship between them. Fundamental problems in engineering are now being solved by optical methods. Stress on materials, thermodynamic properties, elasticity are some of the factors that can be measured or estimated by using optical techniques. The physics behind all these powerful methods is very rich, goes from spectroscopy to photoelasticity. The research in this field aims to understand full scale objects using two and three dimensional models, the strain fields at the surface of materials or constructions, and also on transparent materials such as organic and inorganic glasses and monocrystals. The ability to measure in real time and non-invasively variations of certain physical quantities brought into the solids mechanics some of the measurements needed to compute with speed and accuracy some of the hallmark features. This book takes some examples that covers the most relevant methods in specific applications to some materials and giving a little inside into the physics of the techniques involved. Optical methods in experimental solid mechanics, yielding field information, combined with digital image processing and on-line evaluation of the experimentally obtained data by means of numerical procedures enable the stress-strain analysis of many problems, which couldn't be analysed satisfactorily as yet. Thus the effects of non-linear elastic, of viscoelastic material response and of any combination of such materials on the stress-strain state can be considered. Hybrid techniques, i.e. the combination of measurement techniques with numerical methods for data evaluation based on advanced mathematical algorithms yield reliable knowledge on the actual state and the real reactions of any kind of structures. The possibilities of direct measure are nowadays extremely rare and to measure implies besides manipulation of complex measuring systems, understanding of measurand and limit of application of measurement method. Stress analysis has been considered for some time as a distinct professional branch of engineering, the main objective to determine and improve the mechanical strength of elements, structures and machines. Experimental stress analysis strives to achieve these aims by experimental means. In the investigation of problems of mechanical strength, many factors make the experimental approach indispensable, and often the only means of access. In addition to this, theoretical considerations are usually based on simplifying assumptions which imply certain deviations from reality, and it can be established only by experimentation whether such idealization do not produce an undue distortion of the problem. Using experimental stress analysis is required especially if the analysis is done under real service conditions, where thre are all the influential factors such properties of the employed materials, the methods of manufacture and the operation conditions. A special place among the experimental techniques is occupied by optical methods. Among their numerous possible applications, they can help the researcher to characterize the materials' behaviour, to give access to the time-evolution of fields of data at different scales and maybe, the most important advantage, they are non-contact and provide full-field data that are naturally suitable for direct comparison with numerical solutions.

Earthquake Geology (Hardcover)
An earthquake is always an unexpected phenomenon. Modern science is not able to predict the time or the place or the earthquake strength. The problem of locating the focus of a starting earthquake has not even been set due to the poor level of understanding the processes preceding its start. At present the main earthquake hypothesis is the "explosive" relaxation of the high elastic stresses accumulated in the lithosphere. Understanding a fault's slip behavior, as well as its length and connectivity, is important for constraining the magnitude range and frequency of earthquakes that a particular fault is likely to produce. This book, Earthquake Geology, presents contributions from researchers of different countries in the world that point out the study of seismoinduced phenomena associated with recent and historical earthquakes. First chapter aims to estimate the response of freestanding full-scale equipment to 2% in 50 years hazard level motions, and the results are used to generate ready-to-use fragility curves and second chapter emphasizes on earthquake forecast with the seismic sequence hierarchization method. Third chapter encompasses the micro-earthquake monitoring with sparsely sampled data. In fourth chapter, we analyze in detail the features of the experimental weakening curves and provide a general fit which is purely empirical, with the synthesis of a large number of experiments and their result in terms of frictional breakdown energy Gf. Fifth chapter presents how to locate the focus of a starting earthquake and sixth chapter presents research on earthquake radon anomalies. Seventh chapter highlights on seismic sequence structure and earthquakes triggering patterns and eighth chapter emphasizes on predicting earthquakes with microsequences and reversed phase repetitive patterns. Application of commensurability in earthquake prediction is discussed in ninth chapter and tenth chapter gives out the co-planarity and symmetry theory of earthquake occurrence. Eleventh chapter presents a numerical investigation of earthquake shielding with seismic crystals and twelfth chapter presents an evaluation of strain accumulation in global subduction zones from seismicity data. Thirteenth chapter reveals on modification in atmospheric refractivity and GPS based TEC as earthquake precursors, and fourteenth chapter proposes a seismic-acoustic system for monitoring the earthquake origin process. The aim of fifteenth chapter is to calculate hydrodynamical phenomena: Earth's tidal and precursory variations in level of liquid in wells (boreholes) using identical systems of equations and to clarify data on distribution of hydrodynamical precursors on the Earth's surface. The objective of sixteenth chapter is to provide a wavelet transform method to detect P and S-phases in three component seismic data. In seventeenth chapter, basic models and standard mechanisms of earthquakes are briefly considered, results of processing of information on the earthquakes in the context of global spatial anisotropy caused by the existence of the vector Ag, are presented, and an analysis of them is given. Eighteenth chapter concentrates more on the actual relationship between earthquakes and solar activity and treats the effects causing the correlation only in the aspect of geomagnetic field strength variations. Nineteenth chapter presents a study on correlation of tidal forces with global great earthquakes, and an analysis and verification of forecasting the locations of future large earthquakes is given in last chapter. Forecasts of the locations of future major earthquakes play an important role in earthquake preparedness and determining earthquake insurance costs. Many such forecasts have been carried out with examples in this chapter.
