Surrogates by Robert B. Gramacy Pdf

Computer simulation experiments are essential to modern scientific discovery, whether that be in physics, chemistry, biology, epidemiology, ecology, engineering, etc. Surrogates are meta-models of computer simulations, used to solve mathematical models that are too intricate to be worked by hand. Gaussian process (GP) regression is a supremely flexible tool for the analysis of computer simulation experiments. This book presents an applied introduction to GP regression for modelling and optimization of computer simulation experiments. Features: • Emphasis on methods, applications, and reproducibility. • R code is integrated throughout for application of the methods. • Includes more than 200 full colour figures. • Includes many exercises to supplement understanding, with separate solutions available from the author. • Supported by a website with full code available to reproduce all methods and examples. The book is primarily designed as a textbook for postgraduate students studying GP regression from mathematics, statistics, computer science, and engineering. Given the breadth of examples, it could also be used by researchers from these fields, as well as from economics, life science, social science, etc.

Towards a Professional Model of Surrogate Motherhood by Ruth Walker,Liezl van Zyl Pdf

This book delves deeply into modern surrogacy arrangements, responding to both practical and ethical critiques by offering a radically new model for surrogate motherhood. Current practice distinguishes between two models of surrogacy – the altruistic (unpaid) model and the commercial (paid) model, both of which present social, ethical, and conceptual challenges. This book proposes a novel arrangement for surrogate motherhood – the professional model. Inspired by professions, such as nursing, teaching, and social work, the professional model acknowledges the caring motives that surrogate mothers have while at the same time compensating them for their work. Walker and Van Zyl adopt an evidence-based approach to explain that the professional model enables trust between intended parents and surrogates, provides professional support at every stage of the relationship, affords legal protections against exploitation and commodification, and recognizes the rights and interests of all parties, including the intended baby. The model applies to both transnational and domestic surrogacy and will be of great interest to policy makers, social researchers, bioethicists, legal scholars, fertility professionals, clinicians, and graduate students in psychology, philosophy, medicine and ethics.

The Surrogate by Toni Halleen Pdf

“The Surrogate is a thrilling, high-stakes debut centering on a vulnerable newborn and two women who will do almost anything to claim her as their daughter. With a collection of vividly rendered characters, this twisty tale will leave you thinking about the true meaning of motherhood long after you turn the last page. I loved it!”—Patry Francis, bestselling author of All the Children Are Home Ruth is a no-nonsense fortysomething journalist from the Midwest, desperate for a child with her new husband, Hal. Their hope rests with Cally, a nineteen-year- old who wants to go to college—but doesn’t have the cash. The arrangement seems perfect for everyone. But within a day of the baby’s birth, Cally has a change of heart—and engineers a harrowing escape from the hospital with the newborn. When Ruth and Hal discover that Cally and their daughter are gone, a whole series of doubts and secrets is revealed, and the difference between right and wrong is no longer clear. Set in the vast, sparsely populated upper reaches of northern Minnesota in the middle of winter, The Surrogate follows Ruth, Hal, Cally, through a maze of thought-provoking questions about the nature of family, love, and relationships: What would you do for your partner, when the going gets tough? How much is a pregnancy “worth”? And who, if anyone, “deserves” to be a mother?

The Surrogate by Tania Carver Pdf

Carver's internationally bestselling debut thriller features a very different kind of serial killer. A shocking double-murder scene greets Detective Inspector Philip Brennan when he is called to a flat in Colchester. Two women are viciously cut open and lying spread-eagled, one tied to the bed, one on the floor. The woman on the bed has had her stomach cut into and her unborn child is missing. But this is the third time Phil and his team have seen such an atrocity. Two other pregnant women have been killed in this way and their babies taken from them. No one can imagine what sort of person would want to commit such horrible crimes. When psychologist Marina Esposito is brought in, Phil has to put aside his feelings about their shared past and get on with the job. But can they find the killer before another woman is targeted?

Engineering Design via Surrogate Modelling by Alexander Forrester,András Sobester,Andy Keane Pdf

Surrogate models expedite the search for promising designs by standing in for expensive design evaluations or simulations. They provide a global model of some metric of a design (such as weight, aerodynamic drag, cost, etc.), which can then be optimized efficiently. Engineering Design via Surrogate Modelling is a self-contained guide to surrogate models and their use in engineering design. The fundamentals of building, selecting, validating, searching and refining a surrogate are presented in a manner accessible to novices in the field. Figures are used liberally to explain the key concepts and clearly show the differences between the various techniques, as well as to emphasize the intuitive nature of the conceptual and mathematical reasoning behind them. More advanced and recent concepts are each presented in stand-alone chapters, allowing the reader to concentrate on material pertinent to their current design problem, and concepts are clearly demonstrated using simple design problems. This collection of advanced concepts (visualization, constraint handling, coping with noisy data, gradient-enhanced modelling, multi-fidelity analysis and multiple objectives) represents an invaluable reference manual for engineers and researchers active in the area. Engineering Design via Surrogate Modelling is complemented by a suite of Matlab codes, allowing the reader to apply all the techniques presented to their own design problems. By applying statistical modelling to engineering design, this book bridges the wide gap between the engineering and statistics communities. It will appeal to postgraduates and researchers across the academic engineering design community as well as practising design engineers. Provides an inclusive and practical guide to using surrogates in engineering design. Presents the fundamentals of building, selecting, validating, searching and refining a surrogate model. Guides the reader through the practical implementation of a surrogate-based design process using a set of case studies from real engineering design challenges.

Surrogate Model-Based Engineering Design and Optimization by Ping Jiang,Qi Zhou,Xinyu Shao Pdf

This book covers some of the most popular methods in design space sampling, ensembling surrogate models, multi-fidelity surrogate model construction, surrogate model selection and validation, surrogate-based robust design optimization, and surrogate-based evolutionary optimization. Surrogate or metamodels are now frequently used in complex engineering product design to replace expensive simulations or physical experiments. They are constructed from available input parameter values and the corresponding output performance or quantities of interest (QOIs) to provide predictions based on the fitted or interpolated mathematical relationships. The book highlights a range of methods for ensembling surrogate and multi-fidelity models, which offer a good balance between surrogate modeling accuracy and building cost. A number of real-world engineering design problems, such as three-dimensional aircraft design, are also provided to illustrate the ability of surrogates for supporting complex engineering design. Lastly, illustrative examples are included throughout to help explain the approaches in a more “hands-on” manner.

The Surrogate by Judith Henry Wall Pdf

To a penniless twenty-year-old like Jamie Long, surrogate motherhood seemed both an act of altruism and a financial opportunity. But once pregnant and under contract to Amanda Hartmann, the head of a famous evangelical family, Jamie realizes that she's getting more than she bargained for. Whisked away to the vast, isolated family ranch, she's closely supervised and carefully cut off from the outside world. She learns the family's dark secrets -- and sees the enormity of their ruthlessness. When Jamie hears Amanda's plan to claim the baby as her natural-born child, she begins to suspect that her own life is in danger and resolves to flee. Alone with a tiny newborn, she calls on the one man in the world she can trust -- her high school crush, Joe Brammer. Their love unites them in a struggle to escape, and soon enough their flight becomes a fight for their lives. Brilliantly weaving some of today's most controversial social issues into a captivating page-turner, The Surrogate is Judith Henry Wall's greatest triumph to date.

Surrogate-Based Modeling and Optimization by Slawomir Koziel,Leifur Leifsson Pdf

Contemporary engineering design is heavily based on computer simulations. Accurate, high-fidelity simulations are used not only for design verification but, even more importantly, to adjust parameters of the system to have it meet given performance requirements. Unfortunately, accurate simulations are often computationally very expensive with evaluation times as long as hours or even days per design, making design automation using conventional methods impractical. These and other problems can be alleviated by the development and employment of so-called surrogates that reliably represent the expensive, simulation-based model of the system or device of interest but they are much more reasonable and analytically tractable. This volume features surrogate-based modeling and optimization techniques, and their applications for solving difficult and computationally expensive engineering design problems. It begins by presenting the basic concepts and formulations of the surrogate-based modeling and optimization paradigm and then discusses relevant modeling techniques, optimization algorithms and design procedures, as well as state-of-the-art developments. The chapters are self-contained with basic concepts and formulations along with applications and examples. The book will be useful to researchers in engineering and mathematics, in particular those who employ computationally heavy simulations in their design work.

Surrogate Warfare by Andreas Krieg,Jean-Marc Rickli Pdf

Surrogate Warfare explores the emerging phenomenon of “surrogate warfare” in twenty-first century conflict. The popular notion of war is that it is fought en masse by the people of one side versus the other. But the reality today is that both state and non-state actors are increasingly looking to shift the burdens of war to surrogates. Surrogate warfare describes a patron's outsourcing of the strategic, operational, or tactical burdens of warfare, in whole or in part, to human and/or technological substitutes in order to minimize the costs of war. This phenomenon ranges from arming rebel groups, to the use of armed drones, to cyber propaganda. Krieg and Rickli bring old, related practices such as war by mercenary or proxy under this new overarching concept. Apart from analyzing the underlying sociopolitical drivers that trigger patrons to substitute or supplement military action, this book looks at the intrinsic trade-offs between substitutions and control that shapes the relationship between patron and surrogate. Surrogate Warfare will be essential reading for anyone studying contemporary conflict.

Brown Bodies, White Babies by Laura Harrison Pdf

Focuses on the practice of cross-racial gestational surrogacy, in which a woman--through in-vitro fertilization using the sperm and egg of intended parents or donors--carries a pregnancy for intended parents of a different race. Concentrating on the racial differences between parents and surrogates, Harrison is interested in how reproductive technologies intersect with race, particularly when brown bodies produce white babies. She provides an interdisciplinary analysis that includes legal cases of contested surrogacy, historical examples of surrogacy as a form of racialized reproductive labor, the role of genetics in the assisted reproduction industry, and the recent turn toward reproductive tourism. --From publisher description.
