Solar wind/magnetosheath plasma in the magnetosphere can be identified using a component that has a higher charge state, lower density and, at least soon after their entry into the magnetosphere, lower energy than plasma from a terrestrial source. We survey here observations taken over 3 years of He2+ ions made by the Magnetospheric Ion Composition Sensor (MICS) of the Charge and Mass Magnetosp...

In this paper, we develop a novel approach to nonlinearly retrieving wind field from radial wind data, which are obtained by Single Doppler radar. In general, it is impossible to uniquely recover the 2-D (or 3D) wind field from single Doppler radar, since the problem is underdetermined. In order to overcome the difficulty, according to the characteristic of the wind field distribution, we add t...

Wind energy penetration in power system has been increased very fast and large amount of capitals invested for wind farms all around the world. Meanwhile, in power systems with wind turbine generators (WTGs), the value of Available transfer capability (ATC) is influenced by the probabilistic nature of the wind power. The Mont Carlo Simulation (MCS) is the most common method to model the uncerta...

Ocean wave simulation has a wide range of applications in movies, video games and training systems. Wind force is the main energy resource for generating ocean waves, which are the result of the interaction between wind and the ocean surface. While numerous methods to handle simulating oceans and other fluid phenomena have undergone rapid development during the past years in the field of comput...

Introduction: Wind speed probability at a site has to be modeled for evaluating the energy generation potential of a wind farm. Analytical computation of wind turbine capacity factor at the planning stage of a wind farm is very crucial. Thus, the comparison of Weibull parameters estimation methods and computation of wind turbine capacity factor are the focus of this paper. Case description: Sod...

Original scientific paper The determination of the optimal wind power integration capacity of a large-scale wind farm has become an important issue in power system operation and planning. Reasonable wind power integration capacity can improve the wind energy utilization and save investment for wind farm construction. This paper builds a mathematical model for determining wind farm optimal integ...

The ensemble Monte Carlo simulation is used to calculate the electron-wind forces per unit length of single-walled carbon nanotubes under an electric field applied through the nanotube axis. The electronic system and the ionic system are decoupled from each other. The rate of momentum transferred from the electronic system to the ionic system in the form of the emission or absorption of longitu...

The use of an atmospheric boundary layer (ABL) model is investigated to improve wind retrieval algorithms for NASA scatterometer projects. The ambiguity in wind direction retrieved from scatterometer measurements is removed with the aid of physical directional information obtained from the ABL model. This approach is based on the observation that sea level pressure is scalar and its field is mo...
