Renewal Strings for Cleaning Astronomical Databases [article]

Amos J. Storkey, Nigel C. Hambly, Christopher K. I. Williams, Robert G. Mann
2014 arXiv   pre-print
We have developed renewal strings, a probabilistic technique combining the Hough transform, renewal processes and hidden Markov models which have proven highly effective in this context.  ...  Large astronomical databases obtained from sky surveys such as the SuperCOSMOS Sky Surveys (SSS) invariably suffer from a small number of spurious records coming from artefactual effects of the telescope  ...  The authors also thank IBM for the provision of a p-series machine, Blue Dwarf, to the School of Informatics, Edinburgh.  ...

2020 2020 3rd International Conference on Mechanical, Electronics, Computer, and Industrial Technology (MECnIT)  
This work reviews five photovoltaics (PV) applications Android-based software for smartphones and tablets. The features and advantages of the reviewed application are discussed.  ...  The solar radiation is renewable, clean, and readily available for everyone. Solar radiation can be converted into electricity using devices called solar cells or photovoltaic (PV).  ...  The main important features of the application are:  solar PV Simulator model with real-time data for electricity generation.  shading modeling for calculation of self-shading losses between strings.  ...
