Abstract: Abstract. The simplifying assumption of uniform porosity in studies of wave interaction with porous submerged disks is a major limitation in practical scenarios. This work presents a novel analysis of the heave motion of ...

Abstract: In this study, a simple air-bubble model was developed for unidirectional, homogeneous, plunging-wave propagation over a sloping beach to calculate wave height and wave setup in the surf zone. Two parameters used in the ...

Abstract: A new type of vibration damper for rotor systems has been developed and tested. The damper contains electroviscous fluid which solidifies and provides Coulomb-type friction damping when an ...

Abstract: Fracture and tensile characteristics of asphalt concrete mixtures affect the structural performance of pavements, particularly under low-temperature conditions. This paper reports a study of the tensile and fracture ...

Abstract: Aerosol dispersion in living spaces especially bioaerosols, due to accidents or deliberate acts, is of significant current interest. Computational fluid dynamics (CFD) provides an accurate and detailed platform to study ...

Abstract: The porosity of preformed fired soil aggregates for pores larger than 0.05 μm in radius (POR), which mainly determines the potential of bitumen absorption, cannot be successfully correlated to a single soil property. ...

Abstract: Absorption characteristics of cylindrical soil aggregates manufactured using three soils of different mineralogy and composition and fired to temperatures between 1,922° F (1,050 °C) and 2,282° F (1,250 °C) were assessed ...

Abstract: A steady-state analytical solution is proposed for computing three-dimensional seepage into a partially penetrating ditch drainage system receiving water from an uneven ponding field of finite size. The draining soil is ...

Abstract: Truck lane restriction is one of the most common highway lane management strategies; it ensures that heavy vehicles mostly use the outer lanes of a multilane highway. A higher percentage of heavy vehicles in the design ...

Abstract: Pavement maintenance planning and programming requires optimization analysis involving multiobjective considerations. Traditionally single-objective optimization techniques have been employed by pavement researchers and ...
