Two digital filtering algorithms for fast estimation of symmetrical components in a power system: A static estimation approach
( Elsevier , 2003 , Article)This paper presents the application of two digital filters working together for fast estimation of power systems symmetrical components. The three-phase unbalanced system is transformed to two phases using α–β-transformation. ... -
Two Efficient Techniques to Find Approximate Overlaps between Sequences
(2017 , Article)The next-generation sequencing (NGS) technology outputs a huge number of sequences (reads) that require further processing. After applying prefiltering techniques in order to eliminate redundancy and to correct erroneous ... -
Two Forms Of The Backlund Transformation Of A Third Order Differential Equation
( Qatar University , 1996 , Article)Two explicit forms of Backlund transformation of third order dispersive differential equation are derived. The method of derivation depends on the use of a transformation that couples the equation with its modified one. -
