Non Contact, Remote Sensing of Buried Water Pipeline Leaks Using Infrared Thermography
Subsurface water pipelines, sewer and buried utilities throughout America and the rest of the world range in age from hundreds of years old to brand new. They all have, however, one fact...
The Impact of Global Warming on Water Resources: Overview and Implications for Coastal California
In the past two years, impressive evidence has accumulated that global warming is occurring and is related to the increase in greenhouse gasses. The impact of the warming process on water...
Reservoir Management and Thermal Power Generation
Thermoelectric power stations on regulated rivers may cause violations in stream temperature standards if the dilution water from the upstream reservoir is not adequate. However, it is...
Thin-Walled Finite Element for Curved Multicell Box Girders
The generalized Vlasov's thin-walled beam theory was combined with the finite element technique to develop a new curved thin-walled multicell box girder finite element which can model...
A Finite Difference Approach to the Modelling of Thick Bridge Decks
The finite difference method, although well known as an efficient numerical method, was applied in the past, in the case of slabs, only for the solution of thin slabs. In the present study,...
A Generalized Three Invariants Cap Model and its Numerical Implementation to Study Soil-Foundation Interaction
This paper presents a modified cap model that is capable of characterizing cyclic stress-strain behavior of soils and describing variation of shear strength along various stress paths...
Stress Analysis in Concrete with Cooling Pipes
A substructure method of finite element analysis is adopted in this paper to simulate heat transfer and thermal stresses in a concrete dam. The massive concrete structure is cooled by...
Study of a Computer System for Evaluation of Bearing Wall Stresses in Structural Planning ? Reasoning by Neural Network
This report proposes a reasoning system for bearing shear wall stresses in the ultimate state by using geometrical data of buildings and shear walls at the initial stage of aseismic structural...
Intelligent Optimal CAD (IOCAD) for Arch Dams
The artificial intelligence, optimization methods and CAD techniques are mixed to develop an integrated system for design of arch dams. It includes a knowledge base, a data base, a stress...
A Numerical Procedure to Compute Bearing Capacity of Shallow Foundations
A simple numerical procedure of calculation of bearing capacity of shallow foundation is proposed. This procedure employs the Terzaghi-Prandtl model of general shear failure. In this paper,...
Regional Stress Field Due to Water-Filling at Sanxia Dam
This paper uses the observed stress values to simulate the tectonic stress field in the reservoir. Based on the increment analysis method. we discuss the effects and variations of the...
Nonlinear Trial Load Method of Arch Dams
The trial load method is still an important method for the stress analysis of arch dams at present. However, the trial load method can be used only for the linear elastic analysis of arch...
Time-Dependent Analysis of Nonprismatic Curved PC Box Girder Bridges
The purpose of this paper is to present a step-by-step computer method for predicting the deflection and stress distribution duo to creep and shrinkage of concrete in nonprismatic, curved,...
Rive, Rive-Grown and Burst Probability of Rolled Compressive Concrete Arch Dam
The rive, every step of the rive grown and even burst of arch dam are regarded as sequence random events. Making use of the probability theory and the achievement of elastic, elastic-plastic...
After the Blast
On February 26, 1993, a bomb exploded in an underground parking garage beneath the World Trade Center, killing six, causing hundreds of millions of dollars in damage and leaving a crater...
Cable-in-Conduit Superconductors for MAGLEV Magnet Systems
A major advantage of using a Nb3Sn Cable-in-Conduit Conductor (CICC) for MAGLEV lies in its demonstrated capability to operate in supercritical helium....
Meteorological Forcing on Louisiana Wetlands
The open wetland areas of southern Louisiana are vulnerable to meteorological forcing. On the basis of over one year U.S.G.S. funded measurements of atmospheric pressure, air-sea temperature...
The Use of Geographic Information System Technology to Compare the Environmental Impacts of Human Development on Mobile Bay, Alabama, and Galveston Bay, Texas
Geographic information systems (GIS) can synthesize information rapidly and efficiently from many different sources. GIS-generated maps, which integrate multiple information layers, can...
Formation of Kolkhida Shore During Sea Level Rise
A reconstruction of the Kolkhida coastline evolution during one of the thermal maximum in Holocene was made on the basis of geological data. These data are taken as a principle in calculation...
Waves and Currents Near the Kinburn Spit Extremity
A method of calculation of wave transformation and of currents generated by waves in a surf zone, including a spit extremity is offered. No additional hypothesis on radial stress and wave...
