RISPrediction of the Compressive Strength from Resonant Frequency for Low-Calcium Fly Ash–Based Geopolymer Concrete
Publisher: American Society of Civil Engineers
Abstract: This study focuses on using fly ash to produce a cement-free geopolymer concrete. The combination of potassium hydroxide (KOH) and potassium silicate solution (K2SiO3) was used as the alkaline activator to initiate the ...
Approach to Minimizing the Influence of Changeable Observational Environment on Long-Distance Sea-Crossing Trigonometric Leveling
Publisher: ASCE
Abstract: Instabilities in observed environments at sea, such as the sudden appearance of fog, varying temperature or pressure, changes in wind speed and direction, and differential gravitational and magnetic fields in each observed ...
Stable Reduction of Linear Discrete-Time Systems Via a Multipoint Tangent Phase CFE
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a procedure of linear discrete-time system reduction via a multipoint tangent phase continued-fraction expansion (CFE). The model reduction approach followed starts by transforming ...
Approximation of Irrational Matrix Functions and Its Application to Continuous-Discrete Model Conversion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, an improved method of rational approximation is presented for evaluating the irrational matrix function f(A ), where A is a square matrix and f(s) is a scalar irrational function ...
Evaluation of Cathode Air Flow Transients in a SOFC/GT Hybrid System Using Hardware in the Loop Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermal management in the fuel cell component of a direct fired solid oxide fuel cell gas turbine (SOFC/GT) hybrid power system can be improved by effective management and control of the cathode airflow. The disturbances ...
Thermoeconomic Optimization of a Solid Oxide Fuel Cell and Proton Exchange Membrane Fuel Cell Hybrid Power System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A hybrid system that combines a solid oxide fuel cell (SOFC) with a proton exchange membrane fuel cell (PEMFC) is presented in this paper. The SOFC stack acts as both an electricity producer and the fuel reformer for the ...
Safety Climate in Construction Industry: A Case Study in Hong Kong
Publisher: American Society of Civil Engineers
Abstract: Because of the characteristics of decentralization and mobility in the construction industry, safety culture is crucially important. A comprehensive safety climate questionnaire survey was conducted with all sites and ...
Integrated Design of Axial Slot Casing Treatment and Blades in a Low-Speed Single Stage Axial Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Casing treatment has been used to enhance the stability of axial-flow compressor by extending the stall margin; it also induces strong interaction with compressor blades, as demonstrated in the open literature. Revealing ...
Model Predictive Control for Space Teleoperation Systems Based on a Mixed-H2/H∞ Approach
Publisher: American Society of Civil Engineers
Abstract: In this paper a novel model predictive control (MPC) approach is proposed based on mixed-
Flood Resilience of Urban River Restoration Projects: Case Studies in Hong Kong
Publisher: ASCE
Abstract: As a flood mitigation strategy, most of Hong Kong’s river channels were straightened and lined with concrete to maximize their drainage capacities, but at the cost of ecological and aesthetic values. To reclaim these and ...
