This paper focuses on the analysis of prediction of wind speed in the wind farms. The performance of modeling can be analyzed by using the real time data with different heights of the wind mill. Artificial Neural Network is used here to develop models for predicting wind speed in wind farms. The models are mainly based on back propagation neural network and radial basis function neural network....

Rigorous analysis of the determinants of volumetric mass transfer coefficient (kLa) and its accurate forecasting are of vital importance for effectively designing and operating stirred reactors. Majority of the available literature is limited to systems with low solids concentration, while there has always been a need to investigate the gas-liquid hydrodynamics in tanks handling ...

Superfast muscles (SFMs) are extremely fast synchronous muscles capable of contraction rates up to 250 Hz, enabling precise motor execution at the millisecond time scale. SFM phenotypes have been discovered in most major vertebrate lineages, but it remains unknown whether all SFMs share excitation-contraction coupling pathway adaptations for speed, and if SFMs arose once, or from independent ev...

With the advent of time-based competition, the speed with which new products can be developed and introduced into a market is an important managerial aspect of time-based strategy. The relationship between the allocation of decision-making power within organization and new product development (NPD) speed is investigated empirically using Chinese data. The results of correlation analysis show th...

A summary of numerical computations is presented, in a form designed to aid in operational prediction of surges in the Southern Basin of Lake Michigan. The computations are based upon a dynamical model in which the surge is generated by pressure gradient and wind stress in a squall line which moves across the Basin with constant speed and direction. For each of 25 combinations of squall-line pr...

Light emitting diodes (LEDs) hold several attractive characteristics such as low power consumption, fast switching times, high durability and size reduction to find applications in modern digital communications. This paper presents the design, implementation and suppression of interference due to ambient light sources of a visible light communication system (VLC). The transmitter of the designe...

A large global compilation of altimeter and scatterometer satellite crossover samples is used to address altimeter wind speed inversion. The emphasis here is altimeter wind error due to sea state impacts. Numerous past studies have suggested that long-scale gravity waves, which do not adjust to wind as quickly as the short gravity-capillary waves, have a measurable influence on interpretation o...

In this paper, dynamic modeling of a Vestas 660 kW wind turbine and its validation are performed based on operational data extracted from Eoun-Ebn-Ali wind farm in Tabriz, Iran. The operational data show that the turbine under study, with a classical PI controller, encounters high fluctuations when controlling the output power at its rated value. The turbine modeling is performed by deriving th...

In order to reduce the impact of noise on environment and dissipation useless energy traction motors, this study analyzed a motor by detecting vibration acceleration suspension frame. Field tests were conducted measure frame in commercially operational medium- low-speed maglev train. The showed that as train accelerates, sound pressure grows overall, but increase becomes smaller at each test sp...
