Reply to Collins and Altman [PDF]
European Journal of Cardio-Thoracic Surgery, 2012 We are pleased that EuroSCORE II [1] continues to generate interest and are happy to respond to concerns about its development and evaluation [2]. We find very little to disagree with in the points raised by Collins and Altman [3], but are not convinced that their suggested alternative analysis would have resulted in materially different results.

VISUAL FEEDBACK IN PROBLEMS OF MOVING OBJECTS CONTROL
Міжнародний науково-технічний журнал "Проблеми керування та інформатики", 2006 Possibility of using planar collineation parameters for forming control actions in visual control systems of moving objects is studied. Through examples of solving problems of attitude control, translation motion control and stabilization of screw ...

Intransitive collineation groups of ovals fixing a triangle [PDF]
, 2003 We investigate collineation groups of a finite projective plane of odd order fixing an oval and having two orbits on it, one of which is assumed to be primitive.

On the symmetric block design with parameters (153, 57, 21)
Le Matematiche, 2009 In this paper it is proved that:A) Up to isomorphism and duality there are exactly two possible orbital structures for a putative symmetric block design with parameters (153, 57, 21) constructed using the Frobenius group F_{17·16}B) Up to isomorphism and

GEOMETRIZATION OF A GENERAL COLLINEATION
, 1992 Geometrization of a general collineation means to express the collineation as necessary and sufficient conditions on the kinematic quantities (shear, vorticity, expansion) of the congruence of the vector field generating the collineation.

Collineation groups of the intersection of two classical unitals
, 2001 Kestenband proved in \cite{K1} that there are only seven pairwise non-isomorphic Hermitian intersections in the desarguesian projective plane $\PG(2,\qq)$ of square order $\qq$.

Affine planes admitting a collineation group with a transitive action on the line at infinity [PDF]
, 2010 The affine planes admitting a collineation group with a transitive action on the line at infinity are investigated and an essentially complete classification is achieved when the group is almost simple.
