Distributed Algorithms
Author: Wan FokkinkPublisher: MIT Press
ISBN: 0262318954
Category : Computers
Languages : en
Pages : 242
Book Description
A comprehensive guide to distributed algorithms that emphasizes examples and exercises rather than mathematical argumentation. This book offers students and researchers a guide to distributed algorithms that emphasizes examples and exercises rather than the intricacies of mathematical models. It avoids mathematical argumentation, often a stumbling block for students, teaching algorithmic thought rather than proofs and logic. This approach allows the student to learn a large number of algorithms within a relatively short span of time. Algorithms are explained through brief, informal descriptions, illuminating examples, and practical exercises. The examples and exercises allow readers to understand algorithms intuitively and from different perspectives. Proof sketches, arguing the correctness of an algorithm or explaining the idea behind fundamental results, are also included. An appendix offers pseudocode descriptions of many algorithms. Distributed algorithms are performed by a collection of computers that send messages to each other or by multiple software threads that use the same shared memory. The algorithms presented in the book are for the most part “classics,” selected because they shed light on the algorithmic design of distributed systems or on key issues in distributed computing and concurrent programming. Distributed Algorithms can be used in courses for upper-level undergraduates or graduate students in computer science, or as a reference for researchers in the field.
A Truck Full of Money
Author: Tracy KidderPublisher: Random House Trade Paperbacks
ISBN: 0812985354
Category : Biography & Autobiography
Languages : en
Pages : 290
Book Description
“A perfectly executed, exquisitely reported parable of the Internet age and the wild, mad adventure that is start-up culture.”—Charles Duhigg Fortune, mania, genius, philanthropy—the bestselling author of Mountains Beyond Mountains gives us the inspiring story of Paul English, the founder of Kayak and Lola. Tracy Kidder, the “master of the nonfiction narrative” (The Baltimore Sun) and author of the bestselling classic The Soul of a New Machine, now tells the story of Paul English, a kinetic and unconventional inventor and entrepreneur, who as a boy rebelled against authority. Growing up in working-class Boston, English discovers a medium for his talents the first time he sees a computer. As a young man, despite suffering from what would eventually be diagnosed as bipolar disorder, he begins his pilgrim’s journey through the ups and downs in the brave new world of computers. Relating to the Internet as if it’s an extension of his own mind, he discovers that he has a talent for conceiving innovative enterprises and building teams that can develop them, becoming “a Pied Piper” of geeks. His innovative management style, success, and innate sense of fair play inspire intense loyalty. Early on, one colleague observes: “Someday this boy’s going to get hit by a truck full of money, and I’m going to be standing beside him.” Yet when English does indeed make a fortune, when the travel website Kayak is sold for almost two billion dollars—the first thing he thinks about is how to give the money away: “What else would you do with it?” The second thing he thinks is, What’s next? With the power of a consummate storyteller, Tracy Kidder casts a fresh, critical, and often humorous eye on the way new ideas and new money are reshaping our culture and the world. A Truck Full of Money is a mesmerizing portrait of an irresistibly endearing man who is indefatigable, original, and as unpredictable as America itself. Praise for A Truck Full of Money “Kidder’s prose glides with a figure skater’s ease, but without the glam. His is a seemingly artless art, like John McPhee’s, that conceals itself in sentences that are necessary, economical, and unpretentious.”—The Boston Globe “Kidder’s portrayal of living with manic depression is as nuanced and intimate as a reader might ever expect to get. . . . You can’t help admiring Mr. English and cheering for him.”—The New York Times

Falls and Cognition in Older Persons
Author: Manuel Montero-OdassoPublisher: Springer Nature
ISBN: 3030242331
Category : Medical
Languages : en
Pages : 444
Book Description
Despite of the enormous efforts of researchers and clinicians to understand the pathophysiology of falls in older adults and establish preventive treatments, there is still a significant gap in our understanding and treating of this challenging syndrome, particularly when we focus in cognitively impaired older adults. Falls in older adults are a very common yet complex medical event, being the fifth leading cause of death and a main cause of insidious disability and nursing home placement in our world aging population. Importantly, falls in the cognitively impaired double the prevalence of the cognitively normal, affecting up of 60% of older adults with low cognition and increasing the risk of injuries. The past decade has witnessed an explosion of new knowledge in the role of cognitive processes into the falls mechanisms. This was also accompanied with clinical trials assessing the effect of improving cognition via pharmacological and non-pharmacologic approaches to prevent falls and related injuries. Unfortunately, this revolution in emerging interventions left a gap between clinician-scientists and researchers at academic centers where the new data had been generated and the practitioners who care for cognitively impaired patients with falls. Most advances are published in specialty journals of geriatric medicine, neurology, and rehabilitation. The aim of this book is to reduce this gap and to provide practical tools for fall prevention in cognitively impaired populations. The proposed book is designed to present a comprehensive and state-of the-art update that covers the pathophysiology, epidemiology, and clinical presentation of falls in cognitively impaired older adults. We additionally aim to reduce the knowledge gap in the association between cognitive processes and falls for practitioners from a translational perspective: from research evidence to clinical approach. We will address gaps and areas of uncertainty but also we will provide practical evidence-based guidelines for the assessment, approach, and treatment of falls in the cognitively impaired populations. This book is a unique contribution to the field. Existing textbooks on fall prevention focus in global approaches and only tangentially address the cognitive component of falls and not purposely address special populations and/or settings as residential care and nursing homes. Due to the expected increase of proportion of older adults with cognitive and mobility impairments, this book is also valuable for the whole spectrum of the health care of the elderly. By including a transdisciplinary perspective from geriatric medicine, rehabilitation and physiotherapy medicine, cognitive neurology, and public health, this book will provide a practical and useful resource with wide applicability in falls assessment and prevention.

Relaxed Barrier Function Based Model Predictive Control
Author: Christian FellerPublisher: Logos Verlag Berlin GmbH
ISBN: 3832545441
Category : Technology & Engineering
Languages : en
Pages : 278
Book Description
In this thesis, we introduce the novel concept of relaxed barrier function based model predictive control and present a comprehensive theoretical and algorithmic framework for the design, analysis, and implementation of relaxed barrier function based MPC approaches. Instead of treating the underlying optimization as an idealized static map, a key motive of the MPC results and algorithms presented in this thesis is to study the interconnected dynamics of controlled plant and iterative optimization algorithm in an integrated barrier function based framework and to analyze the resulting overall closed-loop system both from a systems theoretic and algorithmic perspective. One of the presented main results is a novel class of barrier function based anytime MPC algorithms that guarantee important properties of the closed-loop system independently of the number of optimization algorithm iterations that are performed at each sampling step. The obtained theoretical results are illustrated by various numerical examples and benchmark tests as well as by an experimental case study in which the proposed class of barrier function based MPC algorithms is applied to the predictive control of a self-driving car.
