6785.82 руб.
A complete guide to carrying out complex survey analysis using R As survey analysis continues to serve as a core component of sociological research, researchers are increasingly relying upon data gathered from complex surveys to carry out traditional analyses. Complex Surveys is a practical guide to the analysis of this kind of data using R, the freely available and downloadable statistical programming language. As creator of the specific survey package for R, the author provides the ultimate presentation of how to successfully use the software for analyzing data from complex surveys while also utilizing the most current data from health and social sciences studies to demonstrate the application of survey research methods in these fields. The book begins with coverage of basic tools and topics within survey analysis such as simple and stratified sampling, cluster sampling, linear regression, and categorical data regression. Subsequent chapters delve into more technical aspects of complex survey analysis, including post-stratification, two-phase sampling, missing data, and causal inference. Throughout the book, an emphasis is placed on graphics, regression modeling, and two-phase designs. In addition, the author supplies a unique discussion of epidemiological two-phase designs as well as probability-weighting for causal inference. All of the book's examples and figures are generated using R, and a related Web site provides the R code that allows readers to reproduce the presented content. Each chapter concludes with exercises that vary in level of complexity, and detailed appendices outline additional mathematical and computational descriptions to assist readers with comparing results from various software systems. Complex Surveys is an excellent book for courses on sampling and complex surveys at the upper-undergraduate and graduate levels. It is also a practical reference guide for applied statisticians and practitioners in the social and health sciences who use statistics in their everyday work.

The first concept of solid phase synthesis was performed by Merrifield (1) in a dipeptide synthesis from two amino acids. Not surprisingly, Solid phase synthesis did not remain limited to peptides, but also it was extended to heterocycles, so many synthesis methods in solution phase had been transferred to solid phase processes.So, solid phase organic synthesis had become very attractive route of synthesis due to its simplicity of separation of synthetic intermediates from soluble components of a reaction mixture by simple filtration and washing of the resin bound reaction product.

8189 руб.
This book is based on the application of Stochastic programming techniques in Stratified Sampling problems. Stochastic programming deals with a class of optimization models and algorithms in which some of the data may be considered as random. First chapter provides a brief historical sketch of mathematical programming, stochastic programming and its application to various fields including sampling are presented. Various methods namely E-model, modified E-model, Branch and Bound approach and chance constrained programming are used to solve Probabilistic objective function & constraint into an equivalent deterministic. Allocation problems arising in univariate sratified sampling have been considered in first four (II-V) chapters and multivariate case in the last chapter. The problems are solved by first deriving the deterministic equivalents and then by using a suitable convex programming algorithm or by using the Chance constrained technique. Allocation problem in two stage stratified sampling with random parameters in both objective and constraints is also discussed. A numerical example is presented in all chapters and the problems are solved by LINGO software.

Capillary phenomena occur in both natural and human-made systems, from equilibria in the presence of solids (grains, walls, metal wires) to multiphase flows in heterogeneous and fractured porous media. This book, composed of two volumes, develops fluid mechanics approaches for two immiscible fluids (water/air or water/oil) in the presence of solids (tubes, joints, grains, porous media). Their hydrodynamics are typically dominated by capillarity and viscous dissipation. This first volume presents the basic concepts and investigates two-phase equilibria, before analyzing two-phase hydrodynamics in discrete and/or statistical systems (tubular pores, planar joints). It then studies flows in heterogeneous and stratified porous media, such as soils and rocks, based on Darcy’s law. This analysis includes unsaturated flow (Richards equation) and two-phase flow (Muskat equations). Overall, the two volumes contain basic physical concepts, theoretical analyses, field investigations and statistical and numerical approaches to capillary-driven equilibria and flows in heterogeneous systems

7777 руб.
Photorefarctive materials are by far the most suitable medium to generate optical phase conjugation. In particular, BaTiO3 is an attractive one among the candidates of photorefractive materials because of its large electrooptic coefficient that leads to strong coupling for two- and four-wave mixing. High phase conjugate reflectivity is always desired as well as diffraction efficiency for their different potential applications. This book contains the experimental observations of a unique enhancement of the transient diffraction efficiency and phase conjugate reflectivity with steady-state grating in an undoped BaTiO3 crystal. A theoretical explanation behind this enhancement has been proposed for the first time. This book may very helpful for the future researchers on the relevant field.

The deep sea covers over 60% of the surface of the earth, yet less than 1% has been scientifically investigated. There is growing pressure on deep-sea resources and on researchers to deliver information on biodiversity and the effects of human impacts on deep-sea ecosystems. Although scientific knowledge has increased rapidly in recent decades, there exist large gaps in global sampling coverage of the deep sea, and major efforts continue to be directed into offshore research. Biological Sampling in the Deep Sea represents the first comprehensive compilation of deep-sea sampling methodologies for a range of habitats. It reviews the real life applications of current, and in some instances developing, deep-sea sampling tools and techniques. In creating this book the authors have been able to draw upon the experiences of those at the ?coal face? of deep-sea sampling, expanding on the existing methodological texts whilst encompassing a level of technical detail often omitted from journal publications. Ultimately the book will promote international consistency in sampling approaches and data collection, advance the integration of information into global databases, and facilitate improved data analyses and consequently uptake of science results for the management and conservation of the deep-sea environment. The book will appeal to a range of readers, including students, early-career through to seasoned researchers, as well as environmental managers and policy makers wishing to understand how the deep-sea is sampled, the challenges associated with deep survey work, and the type of information that can be obtained.

Selina Boyce and Holden Caulfield are the hero and the heroine of this thesis. The two adolescents come from different backgrounds, different families and even from different ethnicities. The things they have in common, though, are not less significant: they both live in New York and they both have to struggle with the problems of adolescence. In their phase of physical and mental growth these adolescents are going through various stages of dealing with the influence of their new level they enter after their innocent lives as children. Experience versus innocence is what makes the phase of adolescence so confusing and the adults-to-be need to find ways of getting through and over these crises. This is the point of separation for our two heroes. This is the point where the difference between black and white comes in.

Academic Paper from the year 2017 in the subject Environmental Sciences, , course: PhD Environmental Science, language: English, abstract: Groundwater manganese concentration from the Chandrapur district of Central India was assessed during winter 2012. Groundwater sampling was carried out by grab sampling method in 36 sampling locations comprised of 34 hand pumps and two dug wells. Groundwater samples for manganese were preserved by adding conc. Groundwater manganese concentrations were estimated by Inductively Coupled Plasma-Optical Emission Spectroscopy. Groundwater iron concentration from the study area during winter 2012 was in the range of 0.0015-1.85 mg/L (SD±0.36). Groundwater manganese concentration in seven water samples were above the permissible desirable limit of Indian Standards for drinking water (IS 10500:2012, desirable limit for Mn, 0.3 mg/L max.). This elevated concentration of manganese in groundwater from the study area can be attributed to weathering of mineral bearing rocks, mining activities and also to some extent to anthropogenic activities. Spatial distribution of manganese was observed in the study area. Further, shallow, deep and very deep well water had variable manganese concentration. Upper earth surface had lower manganese concentration, however present, can be attributed to anthropogenic activities whereas deeper earth surface had higher manganese concentration that can be assigned to geogenic origin.

Optical systems always process information in parallel. Such a simple optical element as a lens is capable of performing such a difficult task as a Fourier transform. Therefore, when it comes to pattern classification, optical computing is an attractive option. The Phase Only Filter has been showed to be a powerful tool for tracking objects in a two-dimensional plane. In this research, a special tracking technique is developed to overcome weak­nesses of the POF under noisy circumstances. The POF is generally implemented in the 2-D plane. However, the POF has neither been trained as a pattern classifier for one-dimensional data, nor as a multi-dimensional data classifier. Methods are developed in this work to apply the POF to multi-dimensional pattern classification. Moreover, POF equivalent neural network techniques are devised and implemented for pattern classification. Two level neural network is developed for the case of multi-class classification, and a method of training is developed.

В работе рассматривается новый подход к дискретизации уравнений математической физики. Его суть состоит в том, что дискретизация двумерной задачи сводится к дискретизации одномерной задачи, а дискретизация трехмерной задачи сводится к дискретизации двумерной задачи. Рассматриваются многочисленные примеры.Algazin Sergey D. «h-matrix — a new mathematical tool for sampling multidimensional equations of mathematical physics». (In Russian).In operation, the new approach to discretization of the equations of mathematical physics is considered. Its essence consists that discretization of the two-dimensional task is reduced to discretization of the one-dimensional task, and discretization of the three-dimensional task is reduced to discretization of the two-dimensional task. Numerous examples are considered.

Robert Penn Warren Selected Poems of Robert Penn Warren

2372 руб.
John Burt's Selected Poems of Robert Penn Warren is more broadly representative of Warren's poetry than any previous such gartering. More than two hundred poems from every phase grace the volume, a vehicle ideal for sampling or soaking in the finest of Warren's rich output.With each poem. Burt has carefully located the version that constitutes Warren's final revision. His introduction gives an eloquent overview of the poet's career, touching on every published book of verse and highlighting significant lines. A "selected" collection in the truest sense, featuring several previously unpublished pieces, this treasure is at once new and familiar.Burt showcases some very early verse, such as "The Bird and the Stone" and "Oxford City Wall", the only poem known to derive from Warren's days as a Rhodes scholar. There are also portions from the book-length poems, Brother to Dragons and Chief Joseph of the Nez Perce. Arranged chronologically, the selections run the course from darker, more self-consciously formal poems of the 1920s and early 1930s, including "Kentucky Mountain Farm", "Terror", and the most ambitious poem of Warren's early phase, "The Ballad of Billie Potts"; to a looser style and a fusion of personal and political concerns in the 1950s and 1960s.Warren's late phase yielded more than half of his entire poetic opus. A new stylistic boldness elevates his poems to the sublime from 1968 to 1985...

Andreas Beuschel Load Compensation in Three Phase Power Systems

8377 руб.
Inhaltsangabe:Abstract: The object of this thesis is to design software and hardware to obtain the device parameters of a compensator. This compensator should restore the balance and the power factor of a three-phase three-wire system by using reactive elements only. The derived parameters should be accessible remotely and displayed on a PC. L. S. Czarnecki recently presented a highly respected approach to derive the device parameters of the compensating susceptances. He defined the admittances Ye and A which represent the conditions in a three-phase system. He also suggested a way to derive these susceptances by measuring two line-to-line voltages and two line currents. The load balancing technique used in this project was based on Czarnecki’s approach. The first phase of the project concentrated on understanding and proving the theory behind the project by means of computer simulation. The second phase of the project involved writing software for the DSP and building an interface to successfully task the requirements set by the theory. The aspect of being able to transfer the data to a PC via a modem-to-modem connection was taken into account too. In the final stage it is shown that the implemented system is able to derive the necessary parameters in order to balance the currents and restore the power factor as supplied from mains. It was found that even though the supply from the University of Cape Town does not meet the requirements of the theory in terms of harmonic dist...

Kung-Jong Lui Binary Data Analysis of Randomized Clinical Trials with Noncompliance

Подробнее...

9128.23 руб.
It is quite common in a randomized clinical trial (RCT) to encounter patients who do not comply with their assigned treatment. Since noncompliance often occurs non-randomly, the commonly-used approaches, including both the as-treated (AT) and as-protocol (AP) analysis, and the intent-to-treat (ITT) (or as-randomized) analysis, are all well known to possibly produce a biased inference of the treatment efficacy. This book provides a systematic and organized approach to analyzing data for RCTs with noncompliance under the most frequently-encountered situations. These include parallel sampling, stratified sampling, cluster sampling, parallel sampling with subsequent missing outcomes, and a series of dependent Bernoulli sampling for repeated measurements. The author provides a comprehensive approach by using contingency tables to illustrate the latent probability structure of observed data. Using real-life examples, computer-simulated data and exercises in each chapter, the book illustrates the underlying theory in an accessible, and easy to understand way. Key features: Consort-flow diagrams and numerical examples are used to illustrate the bias of commonly used approaches, such as, AT analysis, AP analysis and ITT analysis for a RCT with noncompliance. Real-life examples are used throughout the book to explain the practical usefulness of test procedures and estimators. Each chapter is self-contained, allowing the book to be used as a reference source. Includes SAS programs which can be easily modified in calculating the required sample size. Biostatisticians, clinicians, researchers and data analysts working in pharmaceutical industries will benefit from this book. This text can also be used as supplemental material for a course focusing on clinical statistics or experimental trials in epidemiology, psychology and sociology.

Presents both the fundamental concepts and the most recent applications in solid-phase organic synthesis With its emphasis on basic concepts, Solid-Phase Organic Synthesis guides readers through all the steps needed to design and perform successful solid-phase organic syntheses. The authors focus on the fundamentals of heterogeneous supports in the synthesis of organic molecules, explaining the use of a solid material to facilitate organic synthesis. This comprehensive text not only presents the fundamentals, but also reviews the most recent research findings and applications, offering readers everything needed to conduct their own state-of-the-art science experiments. Featuring chapters written by leading researchers in the field, Solid-Phase Organic Synthesis is divided into two parts: Part One, Concepts and Strategies, discusses the linker groups used to attach the synthesis substrate to the solid support, colorimetric tests to identify the presence of functional groups, combinatorial synthesis, and diversity-oriented synthesis. Readers will discover how solid-phase synthesis is currently used to facilitate the discovery of new molecular functionality. The final chapter discusses how using a support can change or increase reaction selectivity. Part Two, Applications, presents examples of the solid-phase synthesis of various classes of organic molecules. Chapters explore general asymmetric synthesis on a support, strategies for heterocyclic synthesis, and synthesis of radioactive organic molecules, dyes, dendrimers, and oligosaccharides. Each chapter ends with a set of conclusions that underscore the key concepts and methods. References in each chapter enable readers to investigate any topic in greater depth. With its presentation of basic concepts as well as recent findings and applications, Solid-Phase Organic Synthesis is the ideal starting point for students and researchers in organic, medicinal, and combinatorial chemistry who want to take full advantage of current solid-phase synthesis techniques.
