Soliton microcombs generated in nonlinear microresonators facilitate the photonic integration of timing, frequency synthesis, and astronomical calibration functionalities. For these applications, low-repetition-rate soliton are essential as they establish a coherent link between optical microwave signals. However, required pump power typically scales with inverse repetition rate, device footprint square rendering challenging to integrate within circuits. This study designs fabricates silicon...
A vortex ring is a flow phenomenon involving complex toroidal system. When rotor in descending flight, it may enter the state (VRS), which will affect rotor’s aerodynamic characteristics and even endanger it. In this paper, to clarify mechanism by exerts its effects on an axial rotor, unsteady numerical simulation method for integrated with structured moving overset grids proposed validated using experimental data. This then applied analyze of flight. The variations forces slipstream are...
Based on summary information concerning approximately 1600 maritime accidents that occurred from April 2015 to March 2018 in New Zealand, the distribution and correlation of relation three factors, namely, ship group, water area season, was analysed using grey relational analysis, percentage analysis used indicate accident type distribution. In terms occurrence, foreign non-passenger ships domestic fishing vessels ≥ 6 m showed a stronger than other groups, port areas were greater risk zones,...
Based on statistical data of ship total losses globally from 2013 to 2017, correlations between contributory factors (ocean regions, accident causes, and types) are analysed via grey relational analysis (GRA) criteria importance through inter-criteria correction (CRITIC) methods. Each factor is graded into three levels, different scenarios generated the combination these factors. According our analytic results, GRA method appears more sensitive than CRITIC for selecting relevant safety...
This research presents a computational fluid dynamics study for simulating curved cylinder in ocean currents. A rigid cylindrical geometry with two bending directions was modelled uniform and logarithmic flow profiles at maximum Reynolds number of 1.5 × 105; the Realizable k–epsilon formulation is used as turbulence closure model. An analysis force coefficients vortex structure are presented. The results show that will have different hydrodynamic behaviour depending on oncoming direction....
This paper reviews "a vessel of special construction or purpose" in the Convention on International Regulations for Preventing Collisions at Sea – Rule 1(e) and necessity providing a definite interpretation. Accordingly, it discusses regulatory practices some countries several academic perspectives. Dissuasion is made to clarify scope this term, term does not apply conventional ordinary types vessels. In addition, having interpretation may be practical technological development. Finally,...
This study analyses the relationship between vessel groups (small, medium and large) casualty or loss type of UK fishing vehicles based on a summary information concerning casualties losses that occurred vessels in from 2013 to 2020. The establishes control as main cause occurrences for all vessels. Further, flooding/foundering is contributor smaller than 24 m length, grounding/stranding longer. Fishing below 15 length comprise majority losses, while medium-size (15 longer, but less m) make...
