Observation and modeling of surface currents on the Grand Banks: A study of the wave effects on surface currents [PDF]

open access: yesJournal of Geophysical Research, 2007
We investigate the effects of surface waves on surface currents using surface drifter data from the Grand Banks and a coupled current‐wave‐drifter model. The theoretical basis of the study is Jenkins' theory of wave‐current interaction in which wind‐generated surface currents are modified by wind‐wave and wave‐current momentum transfers.

A Synergetic Approach for the Space-Based Sea Surface Currents Retrieval in the Mediterranean Sea

open access: yesRemote Sensing, 2019
We present a method for the remote retrieval of the sea surface currents in the Mediterranean Sea. Combining the altimeter-derived currents with sea-surface temperature information, we created daily, gap-free high resolution maps of sea surface currents ...

Design of Wideband Elliptical Ring Monopole Antenna Using Characteristic Mode Analysis [PDF]

open access: yesJournal of Electromagnetic Engineering and Science, 2021
This paper presents the systematic design of an elliptical ring monopole wideband antenna using characteristic mode analysis. The modal analysis is used to analyze the bandwidth and the radiation performance of the radiating patch.

Current developments in surface electromyography

open access: yesTurkish Journal of Medical Sciences, 2023
Surface electromyography (surface EMG) is a primary technique to detect the electrical activities of muscles through surface electrodes. In recent years, surface EMG applications have grown from conventional fields into new fields. However, there is a gap between the progress in the research of surface EMG and its clinical acceptance, characterized by ...

Validation of OSCAR Surface Currents in the Western Arctic Marginal Seas Against Saildrone Observations

open access: yesEarth and Space Science, 2023
The western Arctic marginal seas undergo large seasonal variation, but are very challenging to observe directly due to sea ice and shallow depths. Deployments of several saildrone uncrewed surface vehicles in the summers of 2018 and 2019 provided unique ...

Analysis of a Compact 4-shaped Annular Ring Ultra Wideband Antenna Using Characteristic Modes [PDF]

open access: yesInternational Journal of Electronics and Telecommunications, 2022
This communication proposes a compact 4-shaped monopole annular ring UWB antenna design. The proposed structure contains multiple radiating strips inside the annular ring, in the form of a 4-shaped and a 50Ω microstrip feed line. A tapered structure with

Wave–current interaction on a free surface [PDF]

open access: yesStudies in Applied Mathematics, 2021
AbstractThe classical water wave equations (CWWEs) comprise two boundary conditions for the two‐dimensional flow on the free surface of a bulk three‐dimensional (3D) incompressible potential flow in the volume bounded by the free surface, which itself moves under the restoring force of gravity.
