Traditional flexure hinges are designed by using a single material, and their performance is inadequate, compared to the ideal hinge.This paper presents a topology-optimization design method for multi-material flexure hinges based on the element stacking method.A topology optimization model for multi-material flexure hinges is constructed to find t
Behavioural symptoms of attention deficit/hyperactivity disorder in preterm and term children born small and appropriate for gestational age: A longitudinal study
Abstract Background It remains unclear whether it is more detrimental to be born too early or too small in relation to symptoms of attention deficit/hyperactivity disorder (ADHD).Thus, we tested whether preterm birth and small body size at birth adjusted for gestational age are Sun Care Lotions independently associated with symptoms of ADHD in chil
Comprehensive evaluation of rock and soil quality of different geological stratum groups in Pingshuo opencast coal mine reclamation area
In order to make scientific and rational use of waste rock and soil in mining areas, guide its classification and discard and reconstruct high quality reclaimed soil, the loess parent material in the Pingshuo opencast mining Gift area is used as a control to analyze the differences in physical and chemical properties of different types of rock and
Numerical simulations of the interactions between counterflowing density currents
The collision and interactions between counterflowing density currents frequently occur in nature and engineering practices along the coastal regions.However, the mechanisms and implications of these interactions remain an active research area.In this study, we developed a high-resolution numerical model to simulate the hydrodynamic characteristics
Multi-Robot Coalitions Formation with Deadlines: Complexity Analysis and Solutions.
Multi-robot task allocation is one of the main problems to address in order to design a multi-robot system, very especially when robots form coalitions that must carry out tasks before a deadline.A lot of factors affect the performance of these systems and among them, this paper is focused on the physical interference Full Panel Bed effect, produce
