Abstract: To predict the properties of asphalt binder from a molecular point of view, energy index was introduced into asphalt binder performance analysis. The stability of asphalt binder was evaluated using energy as an indicator. ...

Abstract: Unhydrated cementitious materials in ultrahigh-performance concrete (UHPC) with a low water-to-binder ratio stop hydrating owing to water shortage but continue hydrating after re-exposure to water; this phenomenon is ...

Abstract: In recent several decades, the study of the cooling methods for the photovoltaic/thermal (PV/T) system has stimulated the interest of many researchers due to the electrical efficiency improvement. However, the PV thermal ...

Abstract: In this study, a thermal cycling method was proposed in the temperature range of 25°C–65°C to investigate the effect of thermal cycling on the elastic modulus of high-performance concretes (HPC40 and HPC60). In addition, ...

Abstract: This paper examines the effects of procedures for both ground motion record selection and scaling on performance-based engineering tools underlying emerging seismic design procedures for engineered wood-frame structures. ...

Abstract: The natural frequency and responses of a micro-electro-mechanical system (MEMS) with time-varying capacitors are determined under an equivalent direct current (DC) voltage. Under alternating current ...

Abstract: A major benefit of utilizing local planetary resources is that it reduces the need and cost of lifting materials from the Earth's surface into Earth orbit. The location of the moon makes it an ideal site for harvesting the ...

Abstract: This paper reports on a study to extend a recently proposed direct displacement design (DDD) procedure for midrise engineered wood-frame structures and develop a set of factors for use in the procedure to meet specified ...
