Approach: The ISO 9126 on software product quality and ISO 12207 on software life cycle processes had been analysed to investigate the r...

Preliminary statement. When I first wrote my lecture notes for the Part II course, Sarah Shea–Simonds very kindly typed the core notes in TeX, and I added to them bit by bit, again in TeX. However, my style was still rather like a telegram, partly as I was trying to save on paper. Now that I am retired, I have time to retype the notes in LaTeX.

And indeed, that will be a major focus of this written statement. However, I also feel compelled to begin with a number of comments that reflect my training as a traditional economist. I am concerned that in the name of "cost savings" and "efficien...

By using the (generalized) Goethals-Seidel array, we construct Hadamard matrices of skew type of order 4n for n = 81,103,151,169, and 463. Hadamard matrices of skew type for these orders are constructed here for the first time. Consequently the list of odd integers n < 300 for which no Hadamard matrix of skew type of order 4n is presently known is reduced to 45 numbers (see the comments after t...
