RISAnalytic and CFD Models for Transient Outburst Flow
Publisher: American Society of Civil Engineers
Abstract: An analytic model (AM) describes the dynamical behavior of a Newtonian fluid that is suddenly released to the atmosphere from a pressurized vessel. The discharge process is a very fast transient phenomenon in which the ...
Dynamic Behavior of a Pedestrian Bridge in Alicante, Spain
Publisher: American Society of Civil Engineers
Abstract: The purpose of this paper is to study the dynamic behavior of a pedestrian bridge in Alicante, Spain, which showed vertical and horizontal vibration problems. Moreover, the deck’s structural steel showed severe corrosion ...
Southern Hemisphere Blocking Onsets Associated with Upper-Tropospheric Divergence Anomalies
Publisher: American Meteorological Society
Abstract: Upper-tropospheric divergence anomalies and divergence tendencies prior to and during the onset of blocking have been investigated for selected cases over the Southern Hemisphere in search of links between the upper-tropospheric ...
Large-Scale Atmospheric Forcing Influencing the Long-Term Variability of Mediterranean Heat and Freshwater Budgets: Climatic Indices
Publisher: American Meteorological Society
Abstract: nterannual to interdecadal precipitation P, evaporation E, freshwater budget (E ? P), and air?sea net heat flux Q have been correlated with the North Atlantic Oscillation (NAO), eastern Atlantic (EA), eastern Atlantic?western ...
Designing Soil-Nailed Walls Using the Amherst Wall Considering Problematic Issues during Execution and Service Life
Publisher: American Society of Civil Engineers
Abstract: Soil nailing is a technique commonly used as a temporary or permanent earth-retention system in soft soils. Habitually, the design of a soil nailing focuses on its performance at failure and computing a safety factor, thus ...
Cerchar Abrasivity Index Estimation of Andesitic Rocks in Ecuador from Petrographical Properties Using Artificial Neural Networks
Publisher: ASCE
Abstract: Rock abrasivity is the main factor that causes erosion of excavation tools and is usually quantified by the Cerchar Abrasivity Index (CAI). Although Cerchar abrasivity tests are easy to perform, they are time consuming and ...
Comparison of Grasping Performance of Tendon and Linkage Transmission Systems in an Electric-Powered Low-Cost Hand Prosthesis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The popularization of fused deposition modeling (FDM) technology and open-source microcontrollers has permitted the explosion of electric hand prostheses that can be designed, shared, built, and operated at a low cost, ...
Design, Control, and Pilot Study of a Lightweight and Modular Robotic Exoskeleton for Walking Assistance After Spinal Cord Injury
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Walking rehabilitation using exoskeletons is of high importance to maximize independence and improve the general well-being of spinal cord injured subjects. We present the design and control of a lightweight and modular ...
Thermal and Illuminance Performance of a Translucent Green Wall
Publisher: American Society of Civil Engineers
Abstract: The aim of this research is to evaluate the energy savings and environmental benefits contributed by vegetal facades in comparison with traditional ones. To this end, a particular type of vegetal facade (translucent green ...
