Abstract: A design procedure to determine the capacity against shear failure of webs of prestressed hollow core slabs is presented. The additional shear stresses in webs caused by prestress forces of strands have been taken into ...

Abstract: Lubricants in hot forging are applied to the heated die surface by spraying dilute water based graphite suspensions through high-pressure nozzles. To avoid undesirable steam formation, these ...

Abstract: This paper describes a practical method to prevent the phenomenon of liquid-column separation in a pipeline by increasing the polar moment of inertia of the rotating parts of a pump-motor unit. Two examples are presented ...

Abstract: The unsteady flow in and near cavity-type geometries, which belongs to a basic class of flow susceptible to self-excited oscillations, occurs in a variety of applications such as slotted-wall ...

Abstract: There are much coal with low content of volatile matter (Vad < 20%), high content of ash (Aad > 50%), low heating caloric (∼10,000 kJ/kg) in China. It is very important to study ...

Abstract: An approximated linear model of unsteady open-channel flow is necessary to design the water-level controller for irrigation open channels. Toward this end, this paper presents the matrix approach to derive the linear model ...

Abstract: In the insurance industry, the actuarial team experiences significant challenges for pricing a competitive but also fair premium and keeping an accurate level of reserve, which leads inevitably to numerous adjustments over ...

Abstract: Separation of microparticles and cells serves a critical step in many applications such as in biological analyses, food production, chemical processing, and medical diagnostics. Sorting on the microscale exhibits certain ...

Abstract: Energy efficiency is an important research topic in rail transit operations. Energy-efficient vertical alignment is a practical consideration during the line design process. Proper vertical alignment can reduce the train ...
