Subsampling by Dimitris N. Politis,Joseph P. Romano,Michael Wolf Pdf
Since Efron's profound paper on the bootstrap, an enormous amount of effort has been spent on the development of bootstrap, jacknife, and other resampling methods. The primary goal of these computer-intensive methods has been to provide statistical tools that work in complex situations without imposing unrealistic or unverifiable assumptions about the data generating mechanism. This book sets out to lay some of the foundations for subsampling methodology and related methods.
Subsampling GPS Receiver Front-end by Carsten Barth Pdf
Research in RFIC design has recently shifted towards direct conversion and subsampling architectures as an alternative to the conventional super-heterodyne architectures. Bandpass sampling architectures, also called subsampling architectures, exhibit several advantages over super-heterodyne architectures, notably, the complexity of subsampling architectures is significantly lower since no phase-locked loop is required. A direct consequence is that downconversion from RF to IF can be achieved with significant power savings as compared to the super-heterodyne architecture. Another significant benefit of such architectures is the capability for processing multiple signals in parallel. The ability to simultaneously handle multiple carriers makes subsampling architectures particularly well suited for GNSS applications, as downconversion of multiple frequency bands is required in GNSS environments. With the advent of the new civilian GPS signals, L2C and L5, and the onset of the new Galileo signal, a receiver that can process multiple signals without adding complexity, is highly desired. An integrated proof-of-concept subsampling GPS receiver front-end in 130 nm BiCMOS is presented in this dissertation. The receiver achieves a noise figure of less than 3.8 dB, the lowest ever recorded noise figure of a subsampling based receiver.
Evaluating the effect of within-household subsampling on the precision of crime victimization rates by Vincent G. Iannacchione,Bonnie E. Shook-Sa Pdf
The decision to select a subsample of eligible members of a sampled household is influenced by a number of factors including burden on the household, data quality, cost, and the sampling variance of survey estimates. Design effects quantify the influence of a complex sampling design on the variance of survey estimates. Selecting a subsample of eligible persons within a sampled household can have counteracting impacts on design effects. On one hand, subsampling increases the design effects attributable to unequal weighting. On the other hand, subsampling could reduce the design effects attributable to clustering because the potential intra-household correlation among respondents in the same household may be reduced or eliminated. If the reduction in correlation is greater than the increase caused by unequal weighting, subsampling can achieve the same sampling variance as selecting all eligible household members, with less cost and burden. We present the results of a simulation study that evaluates the design effects associated with subsampling household members on personal victimization rates based on the 2008 National Crime Victimization Survey, which selected all persons 12 and older in a sampled household.
Digital Subsampling Phase Lock Techniques for Frequency Synthesis and Polar Transmission by Nereo Markulic,Kuba Raczkowski,Jan Craninckx,Piet Wambacq Pdf
This book explains concepts behind fractional subsampling-based frequency synthesis that is re-shaping today’s art in the field of low-noise LO generation. It covers advanced material, giving clear guidance for development of background-calibrated environments capable of spur-free synthesis and wideband phase modulation. It further expands the concepts into the field of subsampling polar transmission, where the newly developed architecture enables unprecedented spectral efficiency levels, unquestionably required by the upcoming generation of wireless standards.

Practical Algorithms for Image Analysis with CD-ROM by Michael Seul,Lawrence O'Gorman,Michael J. Sammon Pdf
This book offers guided access to a collection of algorithms for the digital manipulation and analysis of images. Written in classic 'cookbook' style, it reflects the authors' long experience in this field. For each task, they present a description and implementation of the most suitable procedure in easy-to-use form. The algorithms range from the simplest steps to advanced functions not commonly available for Windows users. Each self-contained section treats a single operation, describing typical situations requiring that operation and discussing the algorithm and implementation. Sections start with a header illustrating the nature of the procedure through a 'before' and 'after' pictorial example and a ready-reference listing typical applications, keywords, and related procedures. At the end of each section are annotated references and a display of program usage for the C programs on the accompanying CD-ROM. Every researcher or practitioner working with images will need this reference and software library.

Outlier Ensembles by Charu C. Aggarwal,Saket Sathe Pdf
This book discusses a variety of methods for outlier ensembles and organizes them by the specific principles with which accuracy improvements are achieved. In addition, it covers the techniques with which such methods can be made more effective. A formal classification of these methods is provided, and the circumstances in which they work well are examined. The authors cover how outlier ensembles relate (both theoretically and practically) to the ensemble techniques used commonly for other data mining problems like classification. The similarities and (subtle) differences in the ensemble techniques for the classification and outlier detection problems are explored. These subtle differences do impact the design of ensemble algorithms for the latter problem. This book can be used for courses in data mining and related curricula. Many illustrative examples and exercises are provided in order to facilitate classroom teaching. A familiarity is assumed to the outlier detection problem and also to generic problem of ensemble analysis in classification. This is because many of the ensemble methods discussed in this book are adaptations from their counterparts in the classification domain. Some techniques explained in this book, such as wagging, randomized feature weighting, and geometric subsampling, provide new insights that are not available elsewhere. Also included is an analysis of the performance of various types of base detectors and their relative effectiveness. The book is valuable for researchers and practitioners for leveraging ensemble methods into optimal algorithmic design.
The Everglades Experiments by Curtis Richardson Pdf
The Florida Everglades ecosystem is recognised world-wide as a significant wetland whose natural processes have been altered and remain threatened. State and Federal US agencies face critical decisions about the course of conservation and restoration efforts. Synthesising nearly ten years of laboratory and field research of the Duke University Wetland Center, this book provides the long-term integrated scientific studies needed to understand the functioning of this region. Background information about the current and historical ecological conditions of the region set the context for reports of long-term research projects, while a series of gradient studies determine the effects of hydrology and nutrient changes. Subsequent sections present models for predicting responses to various conditions and analyse the studies and models, focusing on management and restoration of the Everglades.
The Functional Role of Critical Dynamics in Neural Systems by Nergis Tomen,J. Michael Herrmann,Udo Ernst Pdf
This book offers a timely overview of theories and methods developed by an authoritative group of researchers to understand the link between criticality and brain functioning. Cortical information processing in particular and brain function in general rely heavily on the collective dynamics of neurons and networks distributed over many brain areas. A key concept for characterizing and understanding brain dynamics is the idea that networks operate near a critical state, which offers several potential benefits for computation and information processing. However, there is still a large gap between research on criticality and understanding brain function. For example, cortical networks are not homogeneous but highly structured, they are not in a state of spontaneous activation but strongly driven by changing external stimuli, and they process information with respect to behavioral goals. So far the questions relating to how critical dynamics may support computation in this complex setting, and whether they can outperform other information processing schemes remain open. Based on the workshop “Dynamical Network States, Criticality and Cortical Function", held in March 2017 at the Hanse Institute for Advanced Studies (HWK) in Delmenhorst, Germany, the book provides readers with extensive information on these topics, as well as tools and ideas to answer the above-mentioned questions. It is meant for physicists, computational and systems neuroscientists, and biologists.
Testing and Analysis of GMO-containing Foods and Feed by Salah E. O. Mahgoub,Leo M.L. Nollet Pdf
An increasing number of genetically modified organisms (GMOs) continues to be produced every day. In response to the concerns raised by the development of GMOs and their incorporation in foods and feed, guidelines and regulations to govern and control the use of GMOs and their products have been enacted. These regulations necessitated the design of methods to detect and analyse the presence of GMOs or their products in agriculture produce, food and feed production chains. Design of techniques and instruments that would detect, identify, and quantify GM ingredients in food and feed will help inspection authorities to relay reliable information to consumers who might be concerned about the presence of GM ingredients. Information generated by detection of GMOs in food and feed would be helpful for setting regulations that govern the use of GM components as well as for labeling purposes. Qualitative detection methods of GM-DNA sequences in foods and feeds have evolved fast during the past few years. There is continuous need for the development of more advanced multi-detection systems and for periodic updates of the databases related to these systems. Testing and Analysis of GMO-containing Foods and Feed presents updates and comprehensive views on the various methods and techniques in use today for the detection, identification and quantification of GMOs in foods and feed. The eleven book chapters cover recent developments on sample preparation techniques, immunoassays methods and the PCR technique used in GMO analysis, the use of biosensors in relation to GMO analysis, the application of nucleic acid microarrays for the detection of GMOs, validation and standardization methods for GMO testing, in addition to the type of reference material and reference methods used in GMO testing and analysis. Some of the ISO standards designed for identifying and detecting the presence of GM material in foods are also presented in the book.
Hierarchical and Geometrical Methods in Scientific Visualization by Gerald Farin,Bernd Hamann,Hans Hagen Pdf
The nature of the physical Universe has been increasingly better understood in recent years, and cosmological concepts have undergone a rapid evolution (see, e.g., [11], [2],or [5]). Although there are alternate theories, it is generally believed that the large-scale relationships and homogeneities that we see can only be explainedby having the universe expand suddenlyin a very early “in?ationary” period. Subsequent evolution of the Universe is described by the Hubble expansion, the observation that the galaxies are ?ying away from each other. We can attribute di?erent rates of this expansion to domination of di?erent cosmological processes, beginning with radiation, evolving to matter domination, and, relatively recently, to vacuum domination (the Cosmological Constant term)[4]. We assume throughout that we will be relying as much as possible on observational data, with simulations used only for limited purposes, e.g., the appearance of the Milky Wayfrom nearbyintergalactic viewpoints. The visualization of large-scale astronomical data sets using?xed, non-interactive animations has a long history. Several books and ?lms exist, ranging from “Cosmic View: The Universe in Forty Jumps” [3] by Kees Boeke to “Powers of 10” [6,13] by Charles and Ray Eames, and the recent Imax ?lm “Cosmic Voyage” [15]. We have added our own contribution [9], “Cosmic Clock,” which is an animation based entirely on the concepts and implementation described in this paper.
