nowadays, in consideration of environmental issues and limitation of fossil fuels, there is a particular consideration of renewable energy including ocean energy, that can extracted going through various methods such as wave energy, tidal energy, salinity gradient, otec: ocean thermal energy conversion.herein this research, operation of otec method in southern caspian sea has been discussed. fo...

Renewable energy resources need to be explored to maintain and meet energy demand and replace the slowly depleting fossil fuels.  Malaysia, surrounded by sea with long coastlines, is poised to exploit the potential of this energy. This research work aims at designing a suitable device to extract energy from Malaysian sea current.  Malaysia’s ocean has a low current velocity averaging 0.56 m/s, ...

The underwater Gliders are a kind of autonomous vehicles that have a special role in ocean surveys which demand continuous monitoring and long endurance. Because of low energy consumption and long endurance, these vehicles are favorite for these missions. Among this, a type of gliders can harvest ocean thermal energy, causing significant endurance increase. These vehicles need at least 680 mete...

A new approach to inferring the mass composition of cosmic rays at energies above 10 Abstract We describe a new approach to establishing the mass composition at high energies. Based on measuring both the vertical and inclined shower rates, it has the potential to distinguish heavy nuclei from light nuclei. We apply the method to Haverah Park data above 10 18 eV to show that, under the assumptio...

Meridional structure and transports of energy in the atmosphere, ocean, and land are evaluated holistically for the mean and annual cycle zonal averages over the ocean, land, and global domains, with discussion and assessment of uncertainty. At the top of the atmosphere (TOA), adjusted radiances from the Earth Radiation Budget Experiment (ERBE) and Clouds and Earth’s Radiant Energy System (CERE...

This paper presents an overview of the Ocean wave kinetic energy harvesting system. Energy harvesting is a concept by which energy is captured, stored, and utilized using various sources by employing interfaces, storage devices, and other units. Ocean wave energy harvesting in which the kinetic and potential energy contained in the natural oscillations of Ocean waves are converted into electric...
