Product Description
Photomechanics describes the use of photonics techniques for the nondestructive measurement of variations in certain important physical quantities such as displacements, strains, densities, etc. in experimental solid mechanics and flow. Offering authoritative reviews by internationally recognized experts, the book provides a wealth of information on the essential principles and methods today available in this realm. These include holographic and moiré interferometry, speckle metrology, two- and three-dimensional computer-vision methods as well as laser-Doppler and pulsed-laser velocimetries. The instructive nature of the book makes it an excellent text for physicists and practicing engineers who want to use photomechanics for solving their specific measurement problems and for researchers in various disciplines requiring a broad introduction to the subject.

Using the Dynamic Cone Penetrometer and Light Weight Deflectometer for Construction Quality Assurance
Author: John Siekmeier ; Cassandra Pinta; Scott Merth; Julie Jensen ;Peter Davich; Felipe Camargo; Matthew Beyer | Size: 7.3 MB | Format:PDF | Publisher: Minnesota Department of Transportation Research Services Section 395 John Ireland Boulevard, MS 330 St. Paul, Minnesota 55155-1899 | Year: 2009 | pages: 244 | ISBN: --
The final products resulting from this research implementation project are the specification target values for both granular materials and fine grained soils. For compacted granular material, the grading number and field moisture content are used to select the appropriate DCP and LWD target value. A sieve analysis is used to determine the grading number and an oven dry test or reagent test is typically performed to determine the field moisture content. For compacted fine grained soil, the plastic limit and field moisture content are used to determine DCP and LWD target values. In this case, the plastic limit is used rather than the grading number to classify the soil and is also used to estimate the optimum moisture content for compaction. In addition to these target values, this report provides further standardization of the testing procedures for both the LWD and DCP. This will ensure greater uniformity by personnel conducting these tests. Currently, the method for obtaining a DPI value is varied, involving different numbers of seating drops and measurement drops. Using three seating drops and five to ten measurement drops, depending on the material type, is recommended in this report. LWD testing includes variations as well and the Mn/DOT Grading and Base section is currently defining the seating depth and other aspects of the procedure for implementation during the 2009 construction season. The LWD device is currently non-standardized nationally, allowing manufacturers to develop different models, which produce different measurements. Because Mn/DOT has decided to establish predetermined target values it is necessary to select a specific LWD such that the buffer and plate stiffnesses are also constant along with the specified falling mass, peak force, and plate diameter.

Leaning Tower of Pisa: Behaviour after Stabilization Operations
Author: John B. Burland,Michele B. Jamiolkowski and Carlo Viggiani | Size: 2.5 MB | Format:PDF | Publisher: International Journal of Geoengineering | Year: 2009 | pages: 14
It is well known that the foundations of the Leaning Tower of Pisa were stabilised using the method of
underexcavation to reduce the southward inclination of the Tower by about 10 percent in combination with controlling the
seasonally fluctuating water table beneath the north side. Having been closed to the public since early in 1990, the Tower
was re-opened in December 2001. The paper summarises the response of the Tower during the period of implementation of
the stabilisation works. Monitoring of the movements of the Tower has been continuing and the observations obtained since
2001 are presented. It is shown that over the six years between 2003 and 2008 the induced rate of northward rotation of the
Tower has been steadily reducing to less than 0.2 arc seconds per year. Similarly the rate of induced settlement of the
centre of the foundation has been steadily reducing and is approaching the background rate of settlement of the Piazza.
Piezometer measurements close to the north side of the foundation shows that the drainage system has been successful in
stabilising the groundwater levels beneath the north side of the Tower’s foundation. The paper concludes with a brief
discussion on the possible future behaviour of the Tower.

Author: Ove Ditlevsen, H. O. Madsen | Size: 3 MB | Format:PDF | Publisher: First edition published by John Wiley & Sons Ltd, Chichester | Year: 2007 | pages: 370
Product Description
This book addresses probabilistic methods for the evaluation of structural reliability, including the theoretical basis of these methods. Partial safety factor codes under current practice are briefly introduced and discussed. A probabilistic code format for obtaining a formal reliability evaluation system that catches the most essential features of the nature of the uncertainties and their interplay is then gradually developed. The concepts presented are illustrated by numerous examples throughout the text. The modular approach of the book allows the reader to navigate through the different stages of the methods.

First published in 1958, Salvato's Environmental Engineering has long been the definitive reference for generations of sanitation and environmental engineers. Approaching its fiftieth year of continual publication in a rapidly changing field, the Sixth Edition has been fully reworked and reorganized into three separate, succinct volumes to adapt to a more complex and scientifically demanding field with dozens of specializations.
Updated and reviewed by leading experts in the field, this revised edition offers new process and plant design examples and added coverage of such subjects as urban and rural systems. Stressing the practicality and appropriateness of treatment, the Sixth Edition provides realistic solutions for the practicing public health official, water treatment engineer, plant operator, and others in the domestic and industrial waste treatment professions.
This volume, Environmental Engineering: Water, Wastewater, Soil and Groundwater Treatment and Remediation, Sixth Edition, covers:
- Water treatment
- Water supply
- Wastewater treatment
