This paper deals with the construction of discrete numerical solutions of mixed problems for the telegraph equation. After discretization, the two-variables partial difference mixed problem is solved by means of a discrete eigenfunctions method that mimics the advantages of the continuous eigenfunction method while eliminating its computational(More)
Computed tomography is one of the most promising methods for the non-invasive measurement of the bone mass. A review of the theoretical bases of the double energy technique developed by the authors' experimental study on tubes containing defined calcium concentrations and on cadaver vertebrae, demonstrates the value of this investigation in this field.
