Finite Element study on Oil Tank foundation system
Author: BUI THI YEN | Size: 4.4 MB | Format:PDF | Publisher: National University of Singapore | Year: 2005
The thesis focuses on Oil tank foundation system. The finite element code PLAXIS and PLAXIS 3D Foundation were used for the numerical simulation. The research work is aimed at pursuing the objectives: (1) Numerical analysis for single pile, pile raft analysis and compare to some other established methods to validate the FEM program (2) Back analysis of the centrifuge data of 37 end-bearing pile group underneath the sand pad supporting a model oil tank.
The research work done can be summarized as: (1) Single pile was modeled in both 2D Axisymmetry using Plaxis v8 and 3D using Plaxis 3D Foundation. The results from both analyses are compared in order to check the accuracy of Plaxis 3D Foundation program. Plaxis 3D Foundation also is validated in prediction behavior of a piled raft with 6 other established methods (2) numerical analyses to study the effect of pile cap area, thickness of overlying granular material, number of piles, and stiffness of bed layer of a pile foundation system supporting an oil tank over soft clay. The load distribution among piles, the load transfer characteristics, the maximum settlement, the differential settlement, the shape of settlement and the arching in soil are investigated in each case study. The results are compared to centrifuge data.

PRECISE METHODS FOR ESTIMATING PAVEMENT CLASSIFICATION NUMBER
Author: William W. Jenkinson, Manager, Airport Technology | Size: 1.8 MB | Format:PDF | Publisher: BOEING | Year: 1998 | pages: 137
This document presents methods that can be used by an airport authority to determine Pavement Classification Numbers for both flexible and rigid pavements. The techniques that are recommended are based on the ICAO ACN/PCN method as published in Annex 14. This includes simplified procedures based on using aircraft, as well as a more complex technical analysis that embody pavement characteristics and the traffic mix. The comprehensive methods described in this document are presented in a step-by-step approach, and many examples are included to help explain the processes. Discussion of aircraft loading in excess of the published PCN is based on an extension of the basic ICAO ACN/PCN method of pavement overloading. These procedures will allow the airport authority to assess the impact of individual aircraft overloads, as well as continuous overloading by a fleet of aircraft. Methods are presented that can be used to convert common rating systems such as FAA, LCN, and LCG to a PCN. A complete description of the ACN/PCN procedure as presented in the ICAO Annex 14 is provided.

Despite traffic circles, four-way stop signs, lights regulated by timers or sensors, and other methods, the management of urban intersections remains problematic. Consider that transportation systems have all the features of so-called complex systems: the great number of state and control variables, the presence of uncertainty and indeterminism, the complex interactions between subsystems, the necessity to optimize several optimization criteria, and active behavior of the controlled process, to name just a few. Therefore, a mathematical approach to these systems can resolve their complex issues more elegantly than other methods.
Addressing both efficiency and traffic safety issues, Optimal Traffic Control: Urban Intersections examines the traffic control optimization problem and presents a novel solution method. Using an approach based on control theory, graph theory, and combinatorial optimization, the authors derive a full mathematical description of the traffic control problem and enumerate all combinatorial aspects. The result is a set of algorithmic solutions to various problems along with computer implementation that you can incorporate into real traffic control systems for immediate results. The book concludes by evaluating how the choice of a complete set of signal groups influences intersection performance.
Although modern cities throughout the world have a unique character influenced by culture, geography, and population, most of them share one main feature: busy intersections and the issue of controlling the traffic traveling through them. The development of information technologies, especially computer and telecommunications techniques, has changed the complexity of the problem and influenced the development of new solutions. Clearly stating the issues and presenting a possible solution, this book shows you how to take full advantage of all the capabilities of microprocessor-based traffic signal controllers.

The New Manual of Seismological Observatory Practice (NMSOP or "the Manual") is an initiative of the former Commission on Practice (CoP) of the International Association of Seismology and Physics of the Earth Interior (IASPEI). At its meeting in conjunction with the IASPEI General Assembly in Wellington, New Zealand, January 1994, the CoP established a Working Group on the Manual of Seismological Observatory Practice. Peter Bormann agreed to chair the group. A first concept for the NMSOP was put forward at the General Assembly of IASPEIs European Seismological Commission (ESC) in Athens, Greece, September 1994 (Bormann, 1994). At subsequent meetings and through correspondence, Working Group members were found, willing to contribute major chapters, topical sections or complementary annexes to the Manual. Over the course of time the original conception of the organization of the Manual evolved, in response to the material that authors actually provided. The authorship itself changed as well, as some people dropped out and replacements emerged. This has delayed the completion of the NMSOP. In support of the NMSOP the Manual Working Group organized six open workshop sessions in conjunction with IASPEI and ESC assemblies, with oral and poster presentations as well as Internet presentations of the Manual website under development. The history of the Manual and its forerunners, the activities of the Working Group, as well as the scope, philosophy and expected outreach of the NMSOP, are outlined in more detail in Chapter 1. In total, 40 authors and contributors from nine countries have collaborated in producing about 1250 pages of new drafts (see list of authors and contributors). These were reviewed extensively both within the Working Group and by 35 external reviewers from 10 countries. Thus we hope to have produced a Manual that will be considered useful not only for the daily work of personnel at seismological observatories and centers for data analysis, but which may also find interest in a broader context of education in Earth sciences and training at universities and secondary schools.

Editorial Reviews
From Scientific American
As a meteorologist, I have used least squares, maximum likelihood, maximum entropy, and empirical orthogonal functions during the course of my work, but this book brought together these somewhat disparate techniques into a coherent, unified package ... I recommend it to meteorologists involved with data analysis and parameterization.
Review
"The author has produced a meaningful guide to the subject; one which a student (or professional unfamiliar with the field) can follow without great difficulty and one in which many motivational guideposts are provided....I think that the value of the book is outstanding....It deserves a prominent place on the shelf of every scientist or engineer who has data to interpret."
--GEOPHYSICS
"As a meteorologist, I have used least squares, maximum likelihood, maximum entropy, and empirical orthogonal functions during the course of my work, but this book brought together these somewhat disparate techniques into a coherent, unified package....I recommend it to meteorologists involved with data analysis and parameterization."
--Roland B. Stull, THE BULLETIN OF THE AMERICAN METEOROLOGICAL SOCIETY
"This book provides an excellent introductory account of inverse theory with geophysical applications....My experience in using this book, along with supplementary material in a course for the first year graduate students, has been very positive. I unhesitatingly recommend it to any student or researcher in the geophysical sciences."
--PACEOPH
