Abstract: Multiscale and multimaterial three-dimensional (3D) printing is new frontier in additive manufacturing (AM). It has shown great potential to implement the simultaneous and full control for fabricated object including ...

Abstract: While supercritical water is a perfect coolant with excellent heat transfer, a temporary decrease of the system pressure to subcritical conditions, either during intended transients or by accident, can easily cause a boiling ...

Abstract: Deorbit guidance laws steer a reentry spacecraft from the parking orbit to the entry interface (EI) while satisfying some terminal constraints. The guidance precision has great influence on the shape of the reentry trajectory, ...

Abstract: The method of real options was used to analyze the mechanism of decision-making on adoption of new technology under demand uncertainty in logistics enterprises, the threshold of demand size was then gained. The result shows ...

Abstract: Risk assessment and risk management for deep foundation pit engineering are essential for quality and safety in civil engineering owing to the needs of urban construction projects. However, uncertainty and fuzziness continue ...

Abstract: Hypersonic glide vehicles will be limited by many constraints during their flight course. The flight corridor is defined as the intersection of these constraints and plays an important role in trajectory planning and ...

Abstract: When uncertainties come into play, the leveled baseline schedule obtained by solving the deterministic resource leveling problem can hardly be executed as planned and this schedule may even become infeasible. In addition, ...

Abstract: The filtered-x least mean square (FxLMS) algorithm has been widely used in active noise and vibration control of time-varying structural systems, where the secondary path is estimated online by injecting an auxiliary signal. ...

Abstract: In project management, resources and time are two critical aspects influencing the success of a project. On the one hand, resource leveling, an effective resource optimization technique, is widely adopted to guarantee the ...

Abstract: Determination of the geomechanical parameters and in situ stress of petroleum reservoir rocks by hydraulic fracturing is critical in performing fracturing operations and reservoir simulation in petroleum engineering. Many ...
