M-STATISTICS A comprehensive resource providing new statistical methodologies and demonstrating how new approaches work for applications M-statistics introduces a new approach to statistical inference, redesigning the fundamentals of statistics, and improving on the classical methods we already use. This book targets exact optimal statistical inference for a small sample under one methodological umbrella. Two competing approaches are offered: maximum concentration (MC) and mode (MO) statistics combined under one methodological umbrella, which is why the symbolic equation M=MC+MO. M-statistics defines an estimator as the limit point of the MC or MO exact optimal confidence interval when the confidence level approaches zero, the MC and MO estimator, respectively. Neither mean nor variance plays a role in M-statistics theory. Novel statistical methodologies in the form of double-sided unbiased and short confidence intervals and tests apply to major statistical parameters: - Exact statistical inference for small sample sizes is illustrated with effect size and coefficient of variation, the rate parameter of the Pareto distribution, two-sample statistical inference for normal variance, and the rate of exponential distributions. - - M-statistics is illustrated with discrete, binomial, and Poisson distributions. Novel estimators eliminate paradoxes with the classic unbiased estimators when the outcome is zero. - - Exact optimal statistical inference applies to correlation analysis including Pearson correlation, squared correlation coefficient, and coefficient of determination. New MC and MO estimators along with optimal statistical tests, accompanied by respective power functions, are developed. - - M-statistics is extended to the multidimensional parameter and illustrated with the simultaneous statistical inference for the mean and standard deviation, shape parameters of the beta distribution, the two-sample binomial distribution, and finally, nonlinear regression. Our new developments are accompanied by respective algorithms and R codes, available at GitHub, and as such readily available for applications. M-statistics is suitable for professionals and students alike. It is highly useful for theoretical statisticians and teachers, researchers, and data science analysts as an alternative to classical and approximate statistical inference.

Hidden Addictions - Bridget C Mc Keever - Bog - Taylor & Francis Inc - Plusbog.dk

In Hidden Addictions: A Pastoral Response to the Abuse of Legal Drugs, you’ll find that beneath the gruesome, more public face of illegal drug abuse lies another less hideous, but just as destructive, layer of addiction--the addiction to prescribed drugs. In this revealing study, you’ll learn how you can confront the hidden malady of legal drug dependency in individuals and ultimately break its chokehold on a world already ravaged by complacency and social-systemic dysfunction. The only book of its kind, Hidden Addictions is a concise, readable pastoral perspective on the creeping epidemic of legal drug abuse. Its illuminating case vignettes show you the social roots of addiction and give you the spiritual and religious resources necessary to put you and your loved ones on the road to holistic recovery. Specifically, you’ll read about: - - groups most at risk--girls, young women, and older women - - types of drugs, including tranquilizers, sedatives, antidepressants, and painkillers - - over-the-counter drugs and look-alike drugs - - women and the pharmaceutical industry - - recovery methods, including detoxification, family therapy, and couple counseling - - spiritual resources and systemic reform - In a society already addicted to power, pleasure, and possession, you don’t always see the “warning buttons” being pushed. But this book shows that you can turn back the quiet tide of spiritual sickness and psychochemical dependency that’s sweeping the globe. So whether you’re a pastor whose congregation is suffering, a social worker administering to addicted clientele, or a campus minister, Hidden Addictions will give you the pragmatism and awareness you need to heal the wounded soul.

Complications in Male Circumcision - Fahmy - Bog - Elsevier - Health Sciences Division - Plusbog.dk

Complications in Male Circumcision - Fahmy - Bog - Elsevier - Health Sciences Division - Plusbog.dk

Circumcision remains as one of the most controversial topics in current urological practice. The most important argument against circumcision is the permanent change of anatomy, histology and function of the penis, with potential complications, with rates reported to be low in developed countries, whereas it may be up to 85% when circumcision is carried out by traditional circumcisers, rather than by medically trained professionals in developing countries. In some studies, reporting the complications of circumcision, primary haemorrhage was the most common (52%), whereas infection, meatal stenosis, incomplete circumcision, penile oedema, glandular injury, penile adhesions, iatrogenic hypospadias and urethral injuries were also detected at different rates. At times minor complications after circumcision which cannot be avoided even when the procedure is undertaken by specialized pediatric surgeons or urologist, in a properly equipped centres; specially if the child or his penis is congenitally abnormal, the obvious examples are, circumcising a child with an excessive suprapubic fat or a child with webbed penis or microphallus . This title aims to minimize complications of MC and to compete against its serious impact on men's' health, it will educate and teach physicians about potential complications and how they could manage it early on and avoid further patient problems This title will shed some light over the common as well the uncommon complications, which usually raise a debate about its management. There are different sets to classify MC complications: Either early, or late, minor or major, local or systemic, rare or common. Both rare and common complications will be discussed with comprehensive photos and illustrations for each complication and its operative remedy.

Neural Networks in Chemical Reaction Dynamics - Martin Hagan - Bog - Oxford University Press Inc - Plusbog.dk

Neural Networks in Chemical Reaction Dynamics - Martin Hagan - Bog - Oxford University Press Inc - Plusbog.dk

This monograph presents recent advances in neural network (NN) approaches and applications to chemical reaction dynamics. Topics covered include: (i) the development of ab initio potential-energy surfaces (PES) for complex multichannel systems using modified novelty sampling and feedforward NNs; (ii) methods for sampling the configuration space of critical importance, such as trajectory and novelty sampling methods and gradient fitting methods; (iii) parametrization of interatomic potential functions using a genetic algorithm accelerated with a NN; (iv) parametrization of analytic interatomic potential functions using NNs; (v) self-starting methods for obtaining analytic PES from ab inito electronic structure calculations using direct dynamics; (vi) development of a novel method, namely, combined function derivative approximation (CFDA) for simultaneous fitting of a PES and its corresponding force fields using feedforward neural networks; (vii) development of generalized PES using many-body expansions, NNs, and moiety energy approximations; (viii) NN methods for data analysis, reaction probabilities, and statistical error reduction in chemical reaction dynamics; (ix) accurate prediction of higher-level electronic structure energies (e.g. MP4 or higher) for large databases using NNs, lower-level (Hartree-Fock) energies, and small subsets of the higher-energy database; and finally (x) illustrative examples of NN applications to chemical reaction dynamics of increasing complexity starting from simple near equilibrium structures (vibrational state studies) to more complex non-adiabatic reactions.The monograph is prepared by an interdisciplinary group of researchers working as a team for nearly two decades at Oklahoma State University, Stillwater, OK with expertise in gas phase reaction dynamics; neural networks; various aspects of MD and Monte Carlo (MC) simulations of nanometric cutting, tribology, and material properties at nanoscale; scaling laws from atomistic to continuum; and neural networks applications to chemical reaction dynamics. It is anticipated that this emerging field of NN in chemical reaction dynamics will play an increasingly important role in MD, MC, and quantum mechanical studies in the years to come.

Frequency-Domain Multiuser Detection for CDMA Systems - Rui Dinis - Bog - River Publishers - Plusbog.dk

Frequency-Domain Multiuser Detection for CDMA Systems - Rui Dinis - Bog - River Publishers - Plusbog.dk

Future broadband wireless communication systems are expected to be able to offer new and powerful services enabling fast transmission rates of several tens of Mbit/s. This is an ambitious challenge especially for mobile communication systems since these systems should be able to cope with severely time dispersive channels, associated to the signal multipath propagation. Moreover, these systems should have high spectral and power efficiencies, as well as high capacity and flexibility. Spread spectrum techniques, particularly coded division multiple access (CDMA) techniques allow high capacity and flexibility, continuous transmission requiring low-peak power requirements for the amplifiers, as well as some robustness against fading and time-dispersion effects associated with the multipath propagation. When employed in prefix assisted (PA) block transmission schemes combined with frequency-domain receiver implementations they become especially interesting for broadband wireless systems. In Frequency-Domain Multiuser Detection for CDMA Systems the use of PA block transmission is considered in the context of both DS (Direct Sequence) and MC (Multicarrier) CDMA schemes. The main goal is the study of frequency-domain multiuser detection techniques with iterative signal detection/decoding techniques, also in combination with estimation and cancelation of nonlinear distortion effects. The receiver structures are suitable to scenarios with high interference levels and strongly time-dispersive channels.

Energy Efficient Spectrum Resources Usage in WPANs - Fernando Jose Velez - Bog - River Publishers - Plusbog.dk

Energy Efficient Spectrum Resources Usage in WPANs - Fernando Jose Velez - Bog - River Publishers - Plusbog.dk

Wireless Sensor Networks (WSNs) and the Internet of Things are facing tremendous advances both in terms of energy-efficiency as well as in the number of available applications. Consequently, there are challenges that need to be tackled for the future generation of WSNs. After giving an overview of the WSN protocols and IEEE 802.15.4 standard, this book proposes IEEE 802.15.4 Medium Access Control (MAC) sub-layer performance enhancements by employing not only RTS/CTS combined with packet concatenation but also scheduled channel poling (MC-SCP). Results have shown that the use of the RTS/CTS mechanism improves channel efficiency by decreasing the deferral time before transmitting a data packet. Furthermore, the Sensor Block Acknowledgment MAC (SBACK-MAC) protocol enables more efficiency as it allows the aggregation of several acknowledgement responses in one special Block Acknowledgment (BACK) response packet. The throughput and delay performance have been mathematically derived under both ideal conditions (a channel environment with no transmission errors) and non-ideal conditions (with transmission errors). Simulation results successfully validate the proposed analytical models. This research reveals the importance of an appropriate design for the MAC sub-layer protocol for the desired WSN application. Depending on the mission of the WSN application, different protocols are required. Therefore, the overall performance of a WSN application certainly depends on the development and application of suitable e.g., MAC, network layer protocols.

Introduction to Relativity Volume I - Paul Bruma - Bog - Taylor & Francis Ltd - Plusbog.dk

E=mc² is known as the most famous but least understood equation in physics. This two-volume textbook illuminates this equation and much more through clear and detailed explanations, new demonstrations, a more physical approach, and a deep analysis of the concepts and postulates of Relativity. The first part of Volume I contains the whole Special Relativity theory with rigorous and complete demonstrations. The second part presents the main principles of General Relativity, including detailed explanations of the bending of light in the neighborhood of great masses, the gravitational time dilatation, and the principles leading to the famous equation of General Relativity: D(g) = k .T . The most important cosmological predictions are then described: the Big Bang theory, black holes, and gravitational waves. Plentiful historical information is contained throughout the book, particularly in an ending chapter depicting the scientific and epistemological revolution brought about by the theory of Relativity. Both volumes place an emphasis on the physical aspects of Relativity to aid the reader’s understanding and contain numerous questions and problems (147 in total). Solutions are given in a highly detailed manner to provide the maximum benefit to students. This textbook fills a gap in the literature by drawing out the physical aspects and consequences of Relativity, which are otherwise often second place to the mathematical aspects. Its concrete focus on physics allows students to gain a full understanding of the underlying concepts and cornerstones of Relativity.

The Obama Victory - Bruce W. Hardy - Bog - Oxford University Press Inc - Plusbog.dk

The Obama Victory - Bruce W. Hardy - Bog - Oxford University Press Inc - Plusbog.dk

Barack Obama''s stunning victory in the 2008 presidential election will go down as one of the more pivotal in American history. Given America''s legacy of racism, how could a relatively untested first-term senator with an African father defeat some of the giants of American politics? In The Obama Victory, Kate Kenski, Bruce Hardy, and Kathleen Hall Jamieson draw upon the best voter data available, The National Annenberg Election Survey, as well as interviews with key advisors to each campaign, to illuminate how media, money, and messages shaped the 2008 election. In a crisp, incisive narrative, the authors identify the candidates'' major themes--Maverick versus Mc-Same; Change versus Tax and Spend Liberal, etc.--and then apply them to the five main periods of the campaign: the early summer; the period from the vice presidential nominations through the conventions; the financial meltdown from mid-September to mid-October; the two weeks after the final debate; and the final week. Throughout, they explain how both sides worked the media to reinforce or combat images of McCain as too old and Obama as not ready; how Obama used a very effective rough-and-tumble radio and cable campaign that was largely unnoticed by the mainstream media; how the Vice Presidential nominees impacted the campaign; how McCain''s age and Obama''s race affected the final vote, and much more. Analyzing each nominee''s broadcast, cable, and radio spending, the authors conclude that Obama''s media campaign was more savvy than McCain''s, and that early voting and the complete collapse of campaign finance reform will change elections for years to come. Briskly written and filled with surprising insights, The Obama Victory goes beyond opinion to offer the most authoritative account available of precisely how and why Obama won the presidency.

E=mc² is known as the most famous but least understood equation in physics. This two-volume textbook illuminates this equation and much more through clear and detailed explanations, new demonstrations, a more physical approach, and a deep analysis of the concepts and postulates of Relativity. Volume II contains, notably: - - In Special Relativity: complementary explanations, alternative demonstrations relying on more advanced means and revealing other aspects. Further topics: accelerated objects and the Relativistic force, nuclear reactions, the use of hyperbolic trigonometry, the Lagrangian approach, the Relativistic Maxwell’s equations. - - - In General Relativity: tensors, the affine connection, the covariant derivative, the geodesic equation, the Schwarzschild solution with two of its great consequences: black holes and the bending of light; further axiomatic considerations on time, space, matter, energy and light speed. - - - In Cosmology: the FLRW Metric, the Friedman equation, the cosmological constant, the four ideal cosmological Models. - These subjects are presented in a concrete and incremental manner, and illustrated by many case studies. The emphasis is placed on the theoretical aspects, with rigorous demonstrations based on a minimum set of postulates. The mathematical tools dedicated to Relativity are carefully explained for those without an advanced mathematical background. Both volumes place an emphasis on the physical aspects of Relativity to aid the reader’s understanding and contain numerous questions and problems (147 in total). Solutions are given in a highly detailed manner to provide the maximum benefit to students. This textbook fills a gap in the literature by drawing out the physical aspects and consequences of Relativity, which are otherwise often second place to the mathematical aspects.

As the 1950s gave way to the 1960s, we are accustomed to think, American life passed from a time of placidity to one of turbulence, from complacency to dissent, from consensus to conflict, and from behavioral conformity to the virtues or vices of individual liberation. Some have celebrated this apparent transformation as a necessary change, which helped undermine oppressive racial and sexual hierarchies, challenge the unearned authority of experts, and question the aura surrounding those holding social and political power. Others, including even some critics of the order of things in the Fifties, lament America’s subsequent “unraveling,” due to the confusion and excess that accompanied the erosion of strong foundations for social stability. Either way—viewing the time as a “dark age” or “proud decade”—historians and other observers have generally viewed the 1950s as a period noteworthy for its holism. Things hung together, before they fell apart. Over the past two decades, however, historians have documented the variations and unsettledness of experience, as well as persistent dissent and agitation, that actually marked the 1950s in the United States, despite the apparent unity and strength of “the American way of life.” They have noted not only the depth of the growing black freedom struggle and hints of women’s emancipation underlying the seeming consensus on domesticity but also the presence of sexual rebellion, pacifism, avant-garde aesthetics, and other forms of nonconformity. Moreover, signs of fracture or strain appeared not merely at the margins but in the mainstream of American life. In her re-reading of Fifties women’s magazines, for instance, Joanne Meyerowitz has shown how popular ideology operated in different registers, celebrating domesticity at one moment and independent women breaking into new fields of professional and public distinction at another. We have now become accustomed to see “mass culture,” often believed in that time to homogenize all it touched, as a field in which different actors, different voices, and divergent messages competed for attention. Even without exaggerating the everyday presence of hidden “resistance” to dominant paradigms, it has become much easier to see the midcentury as a time, like others, in which tensions, inconsistency, and uncertainty prevailed in the ways people made sense of their experience. Nonetheless, this recent sensitivity to the complexity of the 1950s cannot erase entirely that which set that time (stretched in our view to span 1948 to 1963) apart from the times before and after it. What was it exactly? Barriers and hierarchies of race and sex were painfully, often brutally real, prevailing alongside some new rhetoric of inclusion and harmony. The growth of purchasing power in prosperous times—and its unevenness—is well documented. The times witnessed the exercise of US military might in the world at large and the “mobilization” of civil society that accompanied it; from this in particular followed a fairly widespread sense that silence or stillness characterized public discourse, even though a few “howled” against it. How do we reconcile the image and reality of the decade as a time of repression with our new knowledge of how much vitality and variousness also coursed through the period? This book proposes that part of the answer lies in recognizing the pre-eminence and pursuit of “centered” ways of thought and imagination in that time, even as the record of experience stubbornly eluded summation in a whole, ordered existence. Intellectual life and cultural awareness (both “popular” and “elite”) put a premium on grasping consensus, coherence, theoretical foundations, ethical universals, and wholeness in things (whether nations, persons, or bodies of knowledge). In other words, American thought and culture in the mid-twentieth century showed a penchant for making sense of things in rounded terms, focused on durable points of orientation, or centers of gravity. Moreover, this disposition held in fields far from entirely “political” (i.e., in the uses of power, the limits of opposition, or pressures to complicity). The urge to determine or locate “centers,” foundations, universals, or orienting norms prevailed across many registers of thought, imagination, and practice. In At the Center, we will explore that mode of perception and reflection as well as the varieties of argument and expression that escaped inclusion within coherent wholes. Our unit of investigation is “the long Fifties”—a span of time extending beyond the calendric markers of the decade, from 1948 to 1963. The socialist writer and organizer Michael Harrington once called 1948 “the last year of the 1930s,” in part referring to the Henry Wallace campaign (and its electoral debacle), the failure to repeal Taft Hartley, and the inability to extend social welfare legislation. In the wake of that watershed, American politics tended (despite the rightward lurch of “Mc
