Figure 1. DVC — an underappreciated neuron that promotes backing. (A) A positive correlation between page views on WormAtlas.org (from September 2013 to October 2014) and published articles mentioning the neuron class in the introduction or discussion section (indexed in Textpresso for C. elegans as of January 2015). (B) Combining metrics from (A) to create a ‘popularity index’ revealed more re...

Wind comfort and wind safety for pedestrians are important requirements in urban areas. Many city authorities request studies of pedestrian wind comfort and wind safety for new buildings and new urban areas. These studies involve combining statistical meteorological data, aerodynamic information and criteria for wind comfort and wind safety. Detailed aerodynamic information can be obtained usin...

An advanced wind tunnel has been introduced as a facility for road vehicle development at the Kindai University (KURING). In this paper, the features of this wind tunnel, which can generate arbitrary patterns of time-varying wind velocities, are first described. There are four representative airflow patterns: steady wind with constant velocity, pulsating wind with oscillating velocity, gusts of...

Due to notable depletion of fuel, non-conventional energy aids the present grid for Power management across the country. Wind energy indeed has major contribution next to solar. Prediction of wind power is essential to integrate wind farms into the grid. Due to intermittency and variability of wind power, forecasting of wind behavior becomes intricate. Wind speed forecasting tools can resolve t...

A data-driven approach for development of a virtual wind-speed sensor for wind turbines is presented. The virtual wind-speed sensor is built from historical wind-farm data by data-mining algorithms. Four different data-mining algorithms are used to develop models using wind-speed data collected by anemometers of various wind turbines on a wind farm. The computational results produced by differe...

Wind turbines as a renewable energy are installed and operated as wind farms in various locations with windy climates.  Connecting micro grids to wind turbines can lead to improved power generation and transmission to distribution networks. Therefore, formulating and configuring the micro-grid connected to the wind turbine requires accurate examination of the configuration of the micro-grid wit...

The wind is one of the most important and affecting phenomena and is known as one of the significant clean resources of energy. Apart from other atmospheric parameters, the wind has complex behavior and intermittent characteristics. Local phenomena can be accompanied by the wind, which is strong, non-predicted, and damaging.  Weather radars are capable of detecting and displaying storm-related ...

Wind turbine is one of the important electrical power sources which have fastest growth rate among renewable energy sources. Several researchers have had contributions in maximizing power efficiency of wind turbines. To take advantages of linear control technique, this paper is devoted to linear the wind turbine nonlinear dynamics with respect to one parameter. Afterwards a fuzzy T-S model is i...

In the present research, the Wind Turbine placement problem for renewable energy utilization is solved using a viral systems optimization algorithm which finds the optimum configuration of wind turbines within a wind farm considering uniform wind-speed, and unidirectional wind. The problem is solved using a single type of turbine and constraining the available space to a flat scenario with a sq...
