This book was released on 2015-09-03 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: We shall examine the validity of 16 experimental designs against 12 common threats to valid inference. By experiment we refer to that portion of research in which variables are manipulated and their effects upon other variables observed. It is well to distinguish the particular role of this chapter. It is not a chapter on experimental design in the Fisher (1925, 1935) tradition, in which an experimenter having complete mastery can schedule treatments and measurements for optimal statistical efficiency, with complexity of design emerging only from that goal of efficiency. Insofar as the designs discussed in the present chapter become complex, it is because of the intransigency of the environment: because, that is, of the experimenter’s lack of complete control.

Available in PDF, EPUB and Kindle. Book excerpt: This monograph provides both a unified account of the development of models and methods for the problem of estimating equilibrium traffic flows in urban areas and a survey of the scope and limitations of present traffic models. The development is described and analyzed by the use of the powerful instruments of nonlinear optimization and mathematical programming within the field of operations research. The first part is devoted to mathematical models for the analysis of transportation network equilibria; the second deals with methods for traffic equilibrium problems. This title will interest readers wishing to extend their knowledge of equilibrium modeling and analysis and of the foundations of efficient optimization methods adapted for the solution of large-scale models. In addition to its value to researchers, the treatment is suitable for advanced graduate courses in transportation, operations research, and quantitative economics.

Available in PDF, EPUB and Kindle. Book excerpt: Traffic Planning and Engineering, Second Edition takes into account underlying trends in traffic planning and engineering. In this edition, Chapter 3 has been remodeled, focusing on the techniques on conducting surveys and their subsequent analysis. Further emphasis has also been provided on environmental management and the central role of computers in all aspects of traffic planning and engineering. The topics discussed in this book include administration and planning in traffic engineering; traffic studies; traffic surveys and analysis; parking; traffic and environmental management; and road user, the vehicle and the road. The traffic stream and capacity; traffic control systems; street lighting, traffic signs, and carriageway markings; and accidents and road safety are also deliberated in this text. This publication is valuable to traffic engineering students, as well as individuals researching on techniques to achieve the safe and efficient movement of people and goods on roadways.

Book excerpt: In the months and weeks before the fateful November 22nd, 1963, Dallas was brewing with political passions, a city crammed with larger-than-life characters dead-set against the Kennedy presidency. These included rabid warriors like defrocked military general Edwin A. Walker; the world's richest oil baron, H. L. Hunt; the leader of the largest Baptist congregation in the world, W.A. Criswell; and the media mogul Ted Dealey, who raucously confronted JFK and whose family name adorns the plaza where the president was murdered. On the same stage was a compelling cast of marauding gangsters, swashbuckling politicos, unsung civil rights heroes, and a stylish millionaire anxious to save his doomed city. Bill Minutaglio and Steven L. Davis ingeniously explore the swirling forces that led many people to warn President Kennedy to avoid Dallas on his fateful trip to Texas. Breathtakingly paced, Dallas 1963 presents a clear, cinematic, and revelatory look at the shocking tragedy that transformed America. Countless authors have attempted to explain the assassination, but no one has ever bothered to explain Dallas-until now. With spellbinding storytelling, Minutaglio and Davis lead us through intimate glimpses of the Kennedy family and the machinations of the Kennedy White House, to the obsessed men in Dallas who concocted the climate of hatred that led many to blame the city for the president's death. Here at long last is an accurate understanding of what happened in the weeks and months leading to John F. Kennedy's assassination. Dallas 1963 is not only a fresh look at a momentous national tragedy but a sobering reminder of how radical, polarizing ideologies can poison a city-and a nation. Winner of the PEN Center USA Literary Award for Research Nonfiction Named one of the Top 3 JFK Books by Parade Magazine. Named 1 of The 5 Essential Kennedy assassination books ever written by The Daily Beast. Named one of the Top Nonfiction Books of 2013 by Kirkus Reviews.
