THIS is a volume honoring Dean L. M. K. Boeiter of UCLA on the occasion of his sixty-fifth birthday, and it-consists of thirty-four technical papers authored by his students, colleagues, and associates. In view of the number of papers involved, it is obvious that, no attempt toward individual review can be made here. Basically, the papers are divided into four categories: (a) Heat-mass transfer and thermodynamics; (6) Materials, mechanics, and design; (c) Engineering education; and (d) City planning.
