基于动态聚集距离的多目标粒子群优化算法及其应用（Multi-objective Particle Swarm Optimization Algorithm Based on Dynamic Crowding Distance and Its Application）
粒子群算法 多目标优化 改进的快速排序法 动态聚集距离 Pareto集
2010/4/1
为了增加Pareto集的多样性，提高多目标优化的全局寻优能力，提出了一种基于动态聚集距离的多目标粒子群算法(DCD-MOPSO)。该算法利用改进的快速排序方法来减少计算量，采用动态变化的惯性权重和加速因子以增强算法的全局寻优能力，并基于动态聚集距离对外部集进行维护以增加Pareto集的多样性。通过典型测试函数的仿真实验和应用实例对DCD-MOPSO算法性能进行了分析，并与多目标优化算法MOPSO和...
Ingestion of bonito extract ameliorates peripheral blood flow in mice loaded from over crowding stress

The Effect of Lower Second Molar Extraction on Late Lower Arch Crowding
Lower Second Molar Extraction Late Lower Arch Crowding
2009/3/2
A preliminary study, finding distal movement of buccal teeth and reduced anterior crowding following lower second molar extraction. Third molar occlusion is not evaluated.
Statistical evaluations finding a tendency for early molar crowding to decrease, with forward molar movement and an increase in anterior crowding.
A study of the relationship between dental crowding and facial morphology in 51 individuals studied over the first five years of the permanent dentition, finding some relationships but no strong or ...
