Effects of herbaceous weed control on young Douglas-fir moisture stress and growth

Creator:: Preest, David Stanley
Abstract:: Profitable, even-aged forest management depends on the early establishment and rapid growth of each new forest crop. These, in turn, require that the young trees have access to an adequate supply of native resources of moisture, nutrients and light. In Mediterranean-type climates, competition for soil moisture is the most serious...

Development and experimental evaluation of branch-and-bound algorithms for determining optimum static job-shop production schedules

Creator:: Ramalingam, P. Rama, 1941-
Abstract:: Branch-and-Bound algorithms are developed to optimally schedule static single- and multi-stage job-shop productions. The 'corollary' of the study is to experimentally verify the effectiveness of branch-and-bound algorithms to overcome the "curse of dimensionality" due to the combinatorial nature of job-shop scheduling problems. The static scheduling problem contemplated in this dissertation...
