Land reclamation - from conventional vertical drain methods to a combined vacuum preloading and electro-osmosis with horizontal drainage enhanced geotextile sheets by Wong, Lung Anthony

“…The major challenges include the extra time required for consolidating the clay slurry and the formation of a working platform for construction, which are not necessary if sandy fill material is adopted. Consolidation analysis of drained reclamation work is a key aspect in assessing the performance of the ground improvement work conducted. …”

Wind tunnel testing of a ducted-fan unmanned aerial vehicle by Shiah, Zi Yang.

“…The experiments were carried out in a closed-loop wind tunnel with the full-scale MAV at different configurations. Coefficients of lift, drag and pitching moment were first discussed in a simple configuration of varying pitch angle with different wing setups without the propeller motor. …”

An experimental and simulation study of chip transportation behaviour in gundrilling by Tnay, Guan Leong

“…From the experiments, terminal velocities of typical gun drill chips at different range of particle Reynolds number were determined to construct the unique drag curve. Based on the findings, a computational fluid dynamic (CFD) numerical model was developed to predict the lateral drag forces with respect to the particle Reynolds number. …”

Determination of operating point for a propulsive wing UAV using CFD by Chan, Chee Shuan

“…CFD simulations were performed using a 2D RANS k-ε turbulence model and the rotating flow was captured using the moving reference frame method. Lift and drag were obtained for different angle of attacks via a control volume analysis of CFD results. …”

Fictions of youth: childness in selected West African novels, 1991-2009 by Moellenberg, T

“…Yet here the thesis also considers some of the downsides to children’s instrumentalization: Jarrett-Macauley and Iweala depersonalize the child figure in their fictions, I argue. The child is drained of a convincing sense of an individuality and agency of his or her own.…”

Conflict-free urban air mobility planning with an airspace-resource-centric approach by Dai, Wei

“…Firstly, we introduce the airspace-resource-centric (ARC) concept for urban airspace management. Whether assuming full implementation of the free-flight concept or adopting the air-route-based architecture will not satisfy the requirement of UAM. …”
