RISDiscussion of “Improvement of Flow in Final Settling Tanks” by Ulrich Bretscher, Peter Krebs, and Willi H. Hager (May/June, 1992, Vol. 118, No. 3)
Publisher: American Society of Civil Engineers
A Protocol to Address User Behavior in the Eco Design of Consumer Products
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Today, it is difficult to integrate the use phase optimization of consumer products into ecodesign methodologies. Current ecodesign approaches are in fact mainly focused on improving the technological performance of products ...
Numerical Analysis Characterizing the Influence of the Evolution of the Length Scale on Strain Localization in Cosserat Media
Publisher: American Society of Civil Engineers
Abstract: In this paper, on the basis of the micropolar (Cosserat) continua approach, a constitutive model for simulation of granular material (e.g., sand) response in the elastoplastic range has been presented. Numerical analyses ...
Predicting Regional Transpiration at Elevated Atmospheric CO2: Influence of the PBL–Vegetation Interaction
Publisher: American Meteorological Society
Abstract: A coupled planetary boundary layer (PBL)?vegetation model is used to study the influence of the PBL?vegetation interaction and the ambient CO2 concentration on surface resistance rs and regional transpiration ?E. Vegetation ...
Wave Runup on Smooth and Rock Slopes of Coastal Structures
Publisher: American Society of Civil Engineers
Abstract: Knowledge on wave‐runup levels is important for a proper design of the crest height of coastal structures. An overall view of the literature supports the assertion that smooth slopes cause the highest possible runup levels. ...
Geometrical Nonlinearities on the Bearing Capacity in Clay: A Validation Data Set for Numerical Tools
Publisher: American Society of Civil Engineers
Abstract: A series of plate loading tests on clay has been conducted in the centrifuge. The aim of the tests is to create a data set, which is freely downloadable, to validate numerical tools that account for geometrical nonlinearities. ...
Case Study on Aggregate Interlock Capacity for the Shear Assessment of Cracked Reinforced-Concrete Bridge Cross Sections
Publisher: American Society of Civil Engineers
Abstract: A 55-year-old bridge showed large cracking in the approach bridge caused by restraint of deformation and support settlement. After repair, it was uncertain at which crack width the traffic loads on the bridge should be ...
Monitoring Fluidization Dynamics for Detection of Changes in Fluidized Bed Composition and Operating Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In many industrial applications of gas-solids fluidized beds, it is worthwhile to have an on-line monitoring method for detecting changes in the hydrodynamics of the bed (due for example to ...
Performance of the Vaisala RS80A/H and RS90 Humicap Sensors and the Meteolabor “Snow White” Chilled-Mirror Hygrometer in Paramaribo, Suriname
Publisher: American Meteorological Society
Abstract: In climate research there is a strong need for accurate observations of water vapor in the upper atmosphere. Radiosoundings provide relative humidity profiles but the accuracy of many routine instruments is notoriously ...
Pilot Proof-Load Test on Viaduct De Beek: Case Study
Publisher: American Society of Civil Engineers
Abstract: For existing bridges, proof-load testing can be a suitable assessment method. This paper addresses the evaluation of a posted reinforced concrete slab bridge over a highway through proof-load testing, detailing the ...
