While the biological flyers often showcase high deformed wing structures, the effects of flexibility on the flapping wing aerodynamics remain inadequately understood. A major challenge in the study of flexible flapping wings is that the resulting wing motion is an outcome of a dynamic balance between the structural dynamics of the wing and the unsteady aerodynamics. Since the effective angle of...

Tension-Leg Platform (TLP) is a vertically moored floating structure. The platform is permanently mooredby tendons. Surge equation of motion of TLP is highly nonlinear because of large displacement and it should be solved with perturbation parameter in time domain. This paper compare the dynamic motion responses of a TLP in regular sea waves obtained by applying three method in time domain usin...

Plasma treatment in foals resulted in greater increases in post-transfusion serum IgG concentrations compared with serum treatment. The results of this study suggest that similar foal serum IgG concentrations can be achieved 3 days post-transfusion by administering 1 unit of plasma product or 2–3 units of serum product. Authors’ addresses: Avon Animal Hospital, 45 Morison Dr., Box 2406, Windsor...

Mangroves are able to attenuate tsunamis, storm surges, and waves. Their protective function against wave disasters is gaining increasing attention as a typical example of the green infrastructure/Eco-DRR (Ecosystem-based Disaster Risk Reduction) in coastal regions. Hydrodynamic models commonly employed additional friction or drag forcing term represent mangrove-induced energy dissipation for s...

The wave energy converter (WEC) system, which extracts electricity through the relative heave motion of two concentric cylinders, comprises an inner cylinder and a torus-type outer sliding along cylinder. To maximize between natural frequencies cylinders must be precisely tuned to resonate situated on each side peak frequency spectrum. However, demerit this strategy is that it demands deep draf...

The tension leg platform (TLP) is a vertically moored structure with excess buoyancy. The TLP is regarded as moored structure in horizontal plan, while inherit stiffness of fixed platform in vertical plane. In this paper, a numerical study using modified Morison equation was carried out in the time domain to investigate the influence of nonlinearities due to hydrodynamic forces and the coupling...

Abstract The latching control represents an attractive alternative to increase the power absorption of wave energy converters (WECs) by tuning phase oscillator velocity excitation phase. However, increasing amplitude motion floating body is not only challenge obtain a good performance WEC. It also depends on efficiency take-off system (PTO). This study aims address actual and operation heaving ...
