The geomagnetic power spectrum
S U M M A R Y Combining CHAMP satellite magnetic measurements with aeromagnetic and marine magnetic data, the global geomagnetic field has now been modelled to spherical harmonic degree 720. An important tool in field modelling is the geomagnetic power spectrum. It allows the comparison of field models estimated from different data sets and can be used to identify noise levels and systematic er...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولMeasurement of power quality indices using advanced spectrum estimation methods
Introduction The quality of voltage waveforms is nowadays an issue of the utmost importance for power utilities, electric energy consumers and also for the manufactures of electric and electronic equipment. The proliferation of nonlinear loads connected to contemporary power systems has triggered a growing concern with power quality issues. The inherent operation characteristics of these loads ...
متن کاملSpurious Dimension Estimates from Time Series of Geomagnetic Indices
1623 Abstract. The tools of nonlinear systems analysis can be used to determine the number of effective degrees of freedom, or dimension, of a system. The algorithms for estimating the dimension appear deceptively simple, but must be applied with extreme care or a spurious dimension estimate is likely to result. We discuss various problems, and methods to overcome them, with estimating the dime...
متن کاملPrincipal component analysis and singular spectrum analysis of ULF geomagnetic data associated with earthquakes
In order to extract any ULF signature associated with earthquakes, the principal component analysis (PCA) and singular spectral analysis (SSA) have been performed to investigate the possibility of discrimination of signals from different sources (geomagnetic variation, artificial noise, and the other sources (earthquake-related ULF emissions)). We adopt PCA to the time series data observed at c...
