Abstract In the paper, a family of novel real-time tuning methods for an unmanned aerial vehicle (UAV) altitude controller in in-flight conditions. The allow controller’s gains to be adapted only on basis measurements from basic sensory equipment and by constructing optimization cost function on-line fashion with virtually no impeding computational complexity; case as this paper hexacopter, wer...

one of the most important and valuable goal of software development life cycle is software cost estimation or sce. during the recent years, sce has attracted the attention of researchers due to huge amount of software project requests. there have been proposed so many models using heuristic and meta-heuristic algorithms to do machine learning process for sce. cocomo81 is one of the most popular...

An experiment was performed to investigate whether or not we are able to use octave generalization in recognizing tunes. The first half of the tune “Yankee Doodle” was chosen as the test sequence. This was universally recognized when played in any one of three octaves. However, when the sequence was played in identical fashion except that each note was chosen randomly from one of the same three...
