Multidimensional sequences are common, and measuring their similarity is a key to any analysis of such data. There is a wealth of similarity measures for sequences in the literature, but most of them are designed for a special type of sequence and later extended to more general types. These extensions are usually ad hoc, and the extended versions may lose the original conceptual interpretation of...
According to theories of Poisson process, compound Poisson process, fuzzy random and product R&D, the fuzzy random forecasting problems on capacity and successful time of enterprise product R&D have been studied, a series of fuzzy random forecasting formulas have been obtained, theories and methods have been put forward to the study of capacity and statistical rule of enterprise product R&D.
Housing affordability is an important factor to evaluate the housing market. It could be decided that whether the housing purchasing power is correspond to price in housing market with the study of this aspect. Housing price to income ratio (PIR) and housing affordability index (HAI) are two important factors to show the housing purchasing power with different way. In this paper, the relation between...
Being as the counterparts of serial robots, parallel manipulators are good at force transmission but not only dexterous manipulation. In this study, a generalized frame-free transmission index is first proposed. Based on the frame-free index, the force transmission performance analysis of spherical 5R parallel manipulators is presented. By giving a specified and significative value, the index can...
Monitoring seasonal changes in vegetation activity over wide areas is essential for many applications, Satellite remote sensing offers a systematic and objective means for detecting and monitoring ecological environment.A large amount of satellite remote sensing data at different spatial, spectral and temporal resolutions was proved to estimate Land cove change.One of the most widely used approaches...
