Genetic algorithms (GAs) are a class of search algorithms based on principles of natural evolution. Hence, incorporating mechanisms used in nature may improve the performance of GAs. In this paper inspired by the mechanisms of complementarity and dominance that broadly exist in nature, we present a new genetic algorithm — Primal-Dual Genetic Algorithm (PDGA). PDGA operates on a pair of chromoso...

this cross-sectional study aimed to determine the reliability of static control evaluation with synapsys posturography system (sps, marseille, france) and to compare the static postural control of deaf children with typically developing children. this study was conducted in 2 phases on 81 children of 7 to 12 years old in tehran schools. the first phase examined the reliability of static balance...

Vegetation water consumption in the Sanjiangyuan Region is of direct significance to utilization local resources. To measure actual evapotranspiration various typical vegetation with different types Region, a Lysimeter was used between November 2019 and October 2020. Additionally, Penman–Monteith equation estimate condensation types. Based on measured data, this paper analyzes spatial distribut...

To improve the accuracy of discrete element simulation parameters for mechanized picking and collection pears, study calibrated pears by method combining a physical experiment simulation. Based on intrinsic four kinds (Snow Crisp Huangguan Qiuyue pears), their models were constructed Hertz-Mindlin with bonding model. The between contact material (PVC, EVA foam material) methods free fall collis...
