On the basis of physical considerations, as usual, Eq. (2) is supplemented with the following boundary value conditions: u ( x, t ) = u x x ( x, t ) = 0, x = 0, 1 (3).
On the basis of physical considerations, equation (1.1) is supplemented with the following boundary conditions: u=0, qquad Delta u=0,quad mbox{in } partialOmegatimes 0,T], (1.2) and the initial condition u x,y,0)=u_{0} x,y),quad mbox{in } Omega.
Even for individuals where decisions are made on the basis of physical considerations, the possible impact on psychological well-being needs to be taken into account.
Where possible, priors should be selected on the basis of physical considerations [ 13]: uniform and Jeffreys' priors have been adopted in cosmology [ 10, 13]; uniform and gamma priors have been employed in biological systems modelling [ 20- 25, 25].
As the MP2 energies are thought to be more accurate on the basis of physical considerations, it is reasonable to assume that the figure of 98% for the Hg N population is similarly more accurate; however, even at the B3LYP level the figures clearly point to this being the form of the molecule expected to be dominant in the gas phase at 350 °C.
