Computer software by George K. Nikas

A keen FORTRAN programmer and computer enthusiast since the 1980s, going as far as programming in Assembly language for 8086 compatible processors and batch programming in MS-DOS, Dr Nikas has developed many complex programs for engineering applications. Following is a list of the main programs developed with the FORTRAN 95 programming language using professional Lahey FORTRAN compilers. Some of these programs were distributed to industrial collaborators under contract with Imperial College London and were developed for the authorís research projects.
