The paper describes a holistic approach for the design of egovernment platforms. It defines principles for architecting a system which must sustain the entire e-government activity of a mid-level public authority (Geneva). The four principles are: Legality, Responsibility, Transparency, and Symmetry. The principles speak to policymakers and to users. They also lead to usable and coherent archit...

For xed matricesM and N , the linear transformation A 7! A MAN is called a displacement of the matrix A. Displacements can simplify matrix equations, as well as matrices themselves. Four principles to solve matrix equations are identi ed: 1) a variety of displacements are needed, 2) we want to recover a matrix from its displacement, 3) changing M and N is natural when A is transposed or inverte...

A self-consistent approach for the evaluation of the existing three-parameter corresponding states principles of non-polar fluids and the calculation of the corresponding states parameters is presented. This self consistent approach is based upon the assumption that the contribution of the third parameter to the thermophysical properties is much smaller than the contributions of the first two p...
