In this study we estimate the prospective tidal current energy resources off the south and west coasts of Korea and explore the influence of modeling tidal current energies based on 15-day versus month-long data records for regimes with pronounced perigean/apogean influences. The tidal current energy resources off southern and western Korea were calculated using 29-day in situ observation data ...
This paper presents an estimation technique using the Kalman filter finite element method ( KFFEM ). Estimation value that is not observed is estimated by KF-FEM, which is the combination method of the Kalman filter and the finite element method. The Kalman filter is employed for the solution of time series analysis and the finite element method is space analysis. In this paper the shallow wate...
Nowadays, energy extraction from sea waves as a renewable energy source has been increasingly considered. In addition, the growing demand for energy as a result of development of industrial activities, air pollution caused by the use of fossil fuels and greenhouse problems caused a new challenge for humankind. Tidal energy is a type of energy that is derived from converting the tidal power of t...
a major part of tidal energy is usually dissipated by the interaction of tidal currents with bottom topography. gulf of oman is a marginal sea which has variable topography and its dominant tidal constituent is m2 semi-diurnal tide. in this paper, the interaction of barotropic tidal current with bottom topography is evaluated. this phenomenon causes the formation of internal tide. internal tide...
Since the 1950s, numerous publications of analytical studies of tidal wave propagations in coastal aquifers have been appeared. This paper reviews the following aspects: importance of tidal effects in studies of coastal areas, analytical studies of tide-induced groundwater flow and related case studies. Finally several important open problems in analytical studies of tide-induced groundwater fl...
Tidal channels are crucial for the functioning of wetlands, though their morphological properties, which are relevant for seafloor habitats and flow, have been understudied so far. Here, we release a dataset composed of Digital Terrain Models (DTMs) extracted from a total of 2,500 linear kilometres of high-resolution multibeam echosounder (MBES) data collected in 2013 covering the entire networ...
abstract: the new neonatal ventilation methods have been developed along with utilization of new technological tools.this device is synchronized with the patient’s respiratory efforts. the ideal synchronized breath needs to be synchronous with initiation, size, and termination of the breath without delay in detecting of initial resiratory effort by device .the synchrony of respiration contribut...
Lung function measurement is difficult in unsedated infants; tidal breathing parameters are a useful non-invasive surrogate, but even these measurements cause disturbance from applying a facemask. We investigated a novel volumetric vest system (FloRight), which measures volume changes of the respiratory system from changes in the magnetic fields induced by current-carrying coils around the enti...
A wetting and drying scheme (WDS) is developed to incorporate into a three-dimensional sigmacoordinate coastal ocean model (POM; Blumberg and Mellor, 1983) with proposing an extended logarithmic profile within and above bed boundary layers to accurately simulate 3D hydrodynamics in extremely shallow coastal seas. While the WDS is simplistically formulated, it can selectively retain the computat...
