Abstract: With low modulus of elasticity, high strength, excellent ductility, excellent durability, and low price, polypropylene fiber is often used in cement-based materials to improve the toughness and anticracking performance of ...

Abstract: The dissolution of ozone and the decomposition of 2-chlorophenol were noticeably enhanced for experiments conducted in the fixed packed contactor than those conducted in a bubble column. The rate of ozone transfer was ...

Abstract: With Wanzhou Yangtze River Bridge as an engineering example, FEM is applied to simulate the whole bridge construction process to optimize the truss member assembling sequences and determine the critical member bars that ...

Abstract: For a thermal flyingheight control (TFC) slider, its heater is usually provided with DC voltage. However, recently, both DC and AC voltages may be supplied to the heater. Unlike supplying AC voltage to the slider and disk ...

Abstract: Due to the volatility, intermittency and, randomness of photovoltaic (PV) power output, hydropower is utilized as a complementary power source. The largest grid-connected hydro-PV power station, the Longyangxia project, ...

Abstract: A hierarchical optimization method is presented for an assessment of the potential maximum energy output of the Three Gorges Project and Gezhouba cascade hydropower stations in China. The optimization incorporates a detailed ...

Abstract: Two feldspars were used as fine aggregates and cement replacement to explore the effect of feldspar dissolution on alkali–silica reaction (ASR) expansion at elevated temperatures (38°C and 60°C). At elevated temperatures, ...

Abstract: In order to save valuable machining time expended on machining bad casting, a point-cloud based analysis is proposed to perform a pre-process check on raw casting material conditions. This analysis virtually compares the ...
