Association of student position in classroom and school performance
(2010)
We analyzed whether the position of students in classroom is correlated with academic performance, and which factors might be involved. The sample consisted of 16 classrooms in a school year bimester, each one with around ...
Mitigation of symmetry condition in positive realness for adaptive control
(Elsevier B.V., 2006-09-01)
Feasibility of nonlinear and adaptive control methodologies in multivariable linear time-invariant systems with state-space realization (A, B, C) is apparently limited by the standard strictly positive realness conditions ...
