The purpose of this Book is to explain the concepts of urban engineering and to highlight some of the challenges faced by this discipline. The overall idea is to describe how urban engineering relates to other areas of engineering expertise, particularly within the context of civil engineering. To do this we have drawn mainly on our own professional and academic experience, fleshed out by an examination of the relevant literature available both in Brazil and further afield. At the outset it should be said that most of our observations focus on the city of São Paulo where our present professional concerns lie. However, in future works we hope to extend our approach beyond the confines of São Paulo in an effort to broaden and improve our understanding of the concepts underlying urban engineering as a necessary prelude to enable us to supply useful guidance for researchers, experts and students keen to work alongside the engineering professionals currently employed in our cities.

Literature review on the geologic aspects of inner shelf cross-shore sediment transport
Author: J. Bailey Smith | Size: 6.9 MB | Format:PDF | Quality:Scanner | Publisher: U.S. Army Engineer Waterways Experiment Station | Year: 1995 | pages: 168
This literature review addresses sediment transport across the inner portion of the continental shelf, also referred to as the shoreface, or, as in this report, the inner shelf (Figure 1). The inner shelf extends from the seaward edge of the surf zone to the landward edge of the continental shelf. It is affected by the strong agitation that results from sediment resuspension caused by shoaling of nonbreaking waves. The inner shelf is frictiondominated by both bottom and sea-surface boundary layers which overlap and frequently occupy the entire water column (Wright, in press). The inner shelf differs from the surf zone, which is also characterized by strong agitation of the bed by waves. The bed of the surf zone, however, is affected by the bore-like translation of waves following wave breaking (Komar 1976), and by wave-induced longshore currents and rip currents.

The object of Topography is to determine the relative positions of points of the earth's surface, that can be referred without error to a tangent plane, and therefore independent of the sphericity of the globe. The operations of a topographical survey, consequently, are two namely, to first project a system of points upon such a tangent plane ; and, secondly, to find the distances of the same above or below the plane; or, in other words, to measure the lengths of the projecting normals. The first process is ordinary surveying; the second, levehng.The results of a topographical survey are laid down in a so-called topograpliical map, which is a representation or complete image of the ground on a reduced scale.
Topographical maps are of the greatest convenience in locating railroads or other roads, in planning irrigation works, draining Avorks, in mining enterprises, in military operations, &c., &c. In a topographical map the configuration of the ground is reduced to an image, which represents to the eye a large area at one glance,which in nature could not be view edbut by many separate inspections ; therefore, the judgment about the relation of the different parts of the work will be a clearer and more intelligent one. This refers especially to mining work, where very frequently the problem occurs, to strike a vein with a tunnel in a certain level. In this problem a correct topographical map will often save the mining company several hundred feet of tunnel work, or, in other words, thousands of dollars.

Although the climate of the Earth is continually changing from the very beginning, anthropogenic effects, the pollution of the air by combustion and industrial activities make it change so quickly that the adaptation is very difficult for all living organisms. Researcher's role is to make this adaptation easier, to prepare humankind to the new circumstances and challenges, to trace and predict the effects and, if possible, even decrease the harmfulness of these changes. In this book we provide an interdisciplinary collection of new studies and findings on the score of air pollution.

Applied Building Physics , Boundary Conditions,Building Performance and Material Properties
Author: Hugo Hens | Size: 91.5 MB | Format:PDF | Quality:Scanner | Publisher: Ernst & Sohn , Wiley Company | Year: 2011 | pages: 322 | ISBN: 9783433029626
The energy crises of the 1970s, persisting moisture problems, complaints about sick buildings, thermal, visual and olfactory discomfort, and the move towards more sustainability in building construction have pushed Building Physics to the forefront of building innovation. The societal pressure to diminish energy consumption in buildings without impairing usability acted as a trigger to activate the whole notion of performance based design and construction. As with all engineering sciences, Building Physics is oriented towards application, which is why, after a first book on fundamentals this second volume examines performance rationale and performance requirements. Outdoor and indoor climate conditions are described and calculation values are discussed, the performance concept is specified at the building level and at the building envelope level, and heat-air-moisture material properties are defined.
The book incorporates 35 years of teaching Building Physics to architectural, building and civil engineers, bolstered by 40 years of experience, research and consultancy.

Author: G. A. WENTWORTH | Size: 8.7 MB | Format:PDF | Quality:Scanner | Publisher: GINN & COMPANY | Year: 1891 | pages: 202
PREFACE :
This edition is intended for teachers, and for them only. The publishers will under no circumstances sell the book except to teachers of Wentworth's Trigonometry ; and every teacher must consider himself in honor bound not to leave his copy where pupils can have access to it, and not to sell his copy except to the publishers, Messrs. Ginn & Company.
It is hoped that young teachers will derive great advantage from studying the systematic arrangement of the work, and that all teachers who are pressed for time will find great relief by not being obliged to work out every problem in the Trigonometry and Surveying.

The Seismicity of Indiana: And its Relationship to Civil Engineering Structures - Phase B
Author: William D Kovacs & W J Murphy | Size: 6.9 MB | Format:PDF | Quality:Original preprint | Publisher: Purdue University | Year: 1977 | pages: 276
The attached Interim Report on the special research project sponsored by the Indiana State Highway Commission and the Administrative Building Council and titled "The Seismicity of Indiana and Its Relationship to Civil Engineering Structures - Phase B" is submitted as partial fulfillment of the objectives of the Study. Specifically the Report fulfills the requirements of Tasks 1 through 5 of the approved work plan for the Study.
The principal investigator, William D. Kovacs, has experienced time and personnel difficulties in conducting the research. He is also on leave of absence during the present year and until the Fall of 1978. A major investigator, Mr. William J. Murphy, returned to engineering practice before the Study was complete but continued to prepare a report of his work on this study while at Purdue. He and Professor Kovacs are the authors of the attached.

Surveying is the art of making measurements which determine the relative position of two or more points. Mine surveying is the art of surveying underground openings, i. e., finding the relative positions of points under the surface, or the position of points underground relative to points upon the surface. The angles and distances measured are usually drawn to scale upon various planes and mine maps thus produced.
In mine surveying there are but few operations different from those of plane surveying. The application of the same principles to the different conditions, along with a greater degree of accuracy, insures success underground.
T. A. 'Donahue, in 'Colliery Surveying,' says: 'Surveying is the art of taking such measurements and observations of an object as will enable a true proportionate representation to be drawn on a plane surface. The principles upon which it depends are all embodied in the science of geometry; so that surveying may be said to be a practical application of geometry.'
Johnson, in his 'Theory and Practice of Surveying,' p. 431, says: 'Surveying is an art, not an exact science.' This should be kept constantly in mind, and in every case that method which promises the minimum deviation from the scientifically correct result should be employed.
