One of the New Features of the Space Power Stations

چکیده
The limited density of an energy flow (DFE) in the Wireless Power Transmission (WPT) systems of the Space Power Stations (SPS) creates a set of difficulties including the huge antenna sizes especially of the receiving ones. It happened so not only by reason to reach the Fresnel area but by reason to transmit enormous power needed for Earth feeding. These circumstances require sometimes dividing the whole antenna square by separate parts. It is a new feature of the WPT of the SPS. This paper is devoted to the problem of a decrease of radiating antenna sizes. Methods and algorithms for finding optimum phase and amplitude distributions in the WPT radiating antenna systems are developed. Numerical methods of the phase synthesis of antennas for a field in the Fresnel area are elaborated. The example of the synthesis field is shown

متن کاملOnline Streaming Feature Selection Using Geometric Series of the Adjacency Matrix of Features
Feature Selection (FS) is an important pre-processing step in machine learning and data mining. All the traditional feature selection methods assume that the entire feature space is available from the beginning. However, online streaming features (OSF) are an integral part of many real-world applications. In OSF, the number of training examples is fixed while the number of features grows with t...

Neighborhoods within the hierarchy of urban structure are one of the smallest socio-physical building blocks of cities. Traditional neighborhoods of Iranian historic cities benefited from strong social relations which were flourished over the years and were manifested in the neighborhoods centers. In the modern era, the new master plans and the complementary local plans have disintegrated th...
