RISFaster Calculations of Sound Radiation from Vibrating Cylinders Using Variational Formulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Prediction of the sound radiation from a vibrating body often requires a computation of the acoustic pressure on the body’s surface, given the normal surface vibration. This paper explores what ...
Anaerobic Biohydrogen Fermentation from Paper Mill Sludge
Publisher: American Society of Civil Engineers
Abstract: Biological hydrogen production from the anaerobic fermentation of ultrasonic-pretreated paper mill sludge started at a pH of 5.5 and a temperature of 36.5°C. When the sludge reaction time (SRT) was 32 h, the organic loading ...
Uniqueness of Solutions to Variationally Formulated Acoustic Radiation Problems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Determination of the surface acoustic pressure given the surface velocity of a vibrating body can be formulated in various ways. However, for some such formulations such as the surface Helmholtz ...
Performance of Elliptical Hollow Sections under Combined Compression and Cyclic Bending
Publisher: American Society of Civil Engineers
Abstract: This paper comprehensively discusses the potential of applying elliptical hollow sections (EHSs) for seismic regions. The study commenced with an experimental investigation of 12 EHS beam-column specimens under combined ...
PSO-GRNN–Based Adaptive Online Vehicle Velocity Prediction Strategy Considering Traffic Information
Publisher: American Society of Civil Engineers
Abstract: In order to increase the online vehicle velocity prediction (VVP) strategy’s forecast performance, an adaptive VVP strategy considering traffic signals is presented for multiple scenarios. Initially, the algorithm of a ...
Multivariate-Parameter Optimization for Photodegradation of Tetracycline by Fe(III)-Citrate Complexes at Near-Neutral pH
Publisher: American Society of Civil Engineers
Abstract: Tetracycline antibiotics have been extensively used in pharmaceutical and veterinary therapies, and they are widely present in natural waters. Although Fe(III)-citrate complexes are known to be highly photoreactive, the ...
Progressive Collapse Analysis of Reticulated Shell Structure under Severe Earthquake Loading Considering the Damage Accumulation Effect
Publisher: American Society of Civil Engineers
Abstract: A reticulated shell is one of the conventional long-span space structures, prone to progressive collapse under a severe earthquake because of its unique single-layer feature. However, the collapse mechanism of this type ...
Exploring the Association between Traffic Safety and Geometric Design Consistency Based on Vehicle Speed Metrics
Publisher: American Society of Civil Engineers
Abstract: Past design consistency research has demonstrated the relationship between operating speeds and geometric design features on two-lane rural highways. However, little is known about the relationship between geometric design ...
Coordinatively Unsaturated Reduced Iron Sites Enable Hemin-Catalyzed Electrochemical Dechlorination of Trichloroethylene
Publisher: ASCE
Abstract: Metal porphyrin structure is believed to be the active site for microbiological reductive dechlorination. In this work, a biomimetic Hemin catalyst was used for the electrochemical dechlorination of trichloroethylene (TCE). ...
