Representative scales of LASPEX wind data
نویسندگان
چکیده
In this study, an attempt is made to identify the appropriate scales for wind data over stations covered in LASPEX experiment, which can be considered represent large-scale pattern, representative of whole area, by field experiment. The divergence was chosen purpose. mean latitudes and longitudes all five calculated represented latitude longitude respectively, central point. components at each were arbitrarily a trigonometric function wavelength distance from point, as origin. values station computed value found. same winds used compute large scale applying method devised Yanai et al. (1973). It seen that wavelengths greater than 2830 km, ratio two divergences 0.9, suggesting limiting entire area.

Improving Data-based Wind Turbine Using Measured Data Foggy Method
The purpose of this paper is to improve the modeling of the data-driven wind turbine system that receives data from noise signals. Most of the data on industrial systems is noisely and data noise is inevitable and natural. The method and idea proposed in this paper, Data Fogging, significantly reduce the impact of noise on data-driven wind turbine system modeling, which is the basis of this met...
متن کاملSelecting Representative Data Sets
A training set is a special set of labeled data providing known information that is used in the supervised learning to build a classification or regression model. We can imagine each training instance as a feature vector together with an appropriate output value (label, class identifier). A supervised learning algorithm deduces a classification or regression function from the given training set...
متن کاملAnisotropy of solar wind turbulence between ion and electron scales.
The anisotropy of turbulence in the fast solar wind, between the ion and electron gyroscales, is directly observed using a multispacecraft analysis technique. Second order structure functions are calculated at different angles to the local magnetic field, for magnetic fluctuations both perpendicular and parallel to the mean field. In both components, the structure function value at large angles...
متن کاملOrigin of Perpendicular Scales in Solar Wind Turbulence
Results of a study of dispersive Alfvén modes propagating outward from the Sun in streaming inhomogeneous plasma are presented for the inner heliosphere (1 AU) region. The results clearly show that a combination of nonlinear wave–particle and wave–wave interactions of outward-only Alfvén modes initially propagating along the local background magnetic field is perfectly capable of explaining th...
متن کاملSelection of representative protein data sets.
The Protein Data Bank currently contains about 600 data sets of three-dimensional protein coordinates determined by X-ray crystallography or NMR. There is considerable redundancy in the data base, as many protein pairs are identical or very similar in sequence. However, statistical analyses of protein sequence-structure relations require nonredundant data. We have developed two algorithms to ex...
