We used conventional tuna hooks (standard Japanese ook size; 3.8 sun) and two sizes of circle hooks (4.3 sun and 5.2 sun) for each fishing operation and compared c...
متن کاملCan optimized effective potentials be determined uniquely?
Local ~multiplicative! effective exchange potentials obtained from the linear-combinationof-atomic-orbital ~LCAO! optimized effective potential ~OEP! method are frequently unrealistic in that they tend to exhibit wrong asymptotic behavior ~although formally they should have the correct asymptotic behavior! and also assume unphysical rapid oscillations around the nuclei. We give an algebraic pro...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
