Estimating Surface Current from HIMAWARI-8 SST Data using Particle Image Velocimetry Method (Case Study in The Flores Sea)

open access: yesIndonesian Journal of Applied Physics, 2023
Four High-Frequency radar systems (HF) have been installed in Indonesia to monitor surface currents. In-situ ocean current observations are relatively expensive and limited by spatial and temporal resolution. Satellite remote sensing enables the estimate

Current fluctuations for independent random walks in multiple dimensions [PDF]

open access: yes, 2010
Consider a system of particles evolving as independent and identically distributed (i.i.d.) random walks. Initial fluctuations in the particle density get translated over time with velocity $\vec{v}$, the common mean velocity of the random walks ...

Phenotypic responses to water flow and wave exposure in aquatic plants

open access: yesActa Societatis Botanicorum Poloniae, 2011
Plastic responses of 10 aquatic plant species from 5 rivers and 5 lakes in NW Poland were examined. Chara fragilis, C. delicatula, Potamogeton pectinatus, P. perfoliatus, P.

Velocity of Electric Currents [PDF]

open access: yesNature, 1919
WHILE the velocity of electric waves is well known, as Maxwell and Heaviside have pointed out, we know absolutely nothing of the velocity with which electricity travels in a wire. As Heaviside says (“Papers”, vol. ii., p. 3, line 4):—“It may be an inch an hour or it may be immensely great”.

Minimization of Ohmic losses for domain wall motion in a ferromagnetic nanowire [PDF]

open access: yes, 2010
We study current-induced domain-wall motion in a narrow ferromagnetic wire. We propose a way to move domain walls with a resonant time-dependent current which dramatically decreases the Ohmic losses in the wire and allows to drive the domain wall with ...

Study of the transformation of pollution caused by cyclones passing over the sea of Azov

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2016
The processes of transfer and diffusion of contaminants in the Sea of Azov in the case of cyclonic atmospheric pertubations were studied using a threedimensional nonlinear mathematical model.

Hydrodynamic and Inundation Modeling of China’s Largest Freshwater Lake Aided by Remote Sensing Data

open access: yesRemote Sensing, 2015
China’s largest freshwater lake, Poyang Lake, is characterized by rapid changes in its inundation area and hydrodynamics, so in this study, a hydrodynamic model of Poyang Lake was established to simulate these long-term changes.

Virtual Metrology Filter-Based Algorithms for Estimating Constant Ocean Current Velocity

open access: yesRemote Sensing, 2023
The strap-down inertial navigation system (SINS) and Doppler velocity log (DVL) integrated navigation system are widely used for autonomous underwater vehicles (AUVs). Whereas DVL works in the water tracking mode, the velocity provided by DVL is relative

Numerical Simulation of a Sandy Seabed Response to Water Surface Waves Propagating on Current

open access: yesJournal of Marine Science and Engineering, 2018
An integrated numerical model is developed to study wave and current-induced seabed response and liquefaction in a flat seabed. The velocity-inlet wave-generating method is adopted in the present study and the finite difference method is employed to ...

The effect of variable turbulent intensities on the distribution of zooplankton in the shallow, large Lake Balaton (Hungary)

open access: yesKnowledge and Management of Aquatic Ecosystems, 2011
The influence of current velocity on zooplankton organisms is manifold. Moderate current velocity is beneficial for zooplankton, but through various mechanisms too high a current velocity can have detrimental effects.
