Packing Spheres into a Minimum-Height Parabolic Container

Axioms
Sphere packing consists of placing several spheres in a container without mutual overlapping. While packing into regular-shape containers is well explored, less attention is focused on containers with nonlinear boundaries, such as ellipsoids or ...

Linkage Mechanism Optimization and Sensitivity Analysis of an Automotive Engine Hood

International Journal of Automotive Science and Technology, 2018
Equipment such as a rod between vehicle body and hood or a lift strut are used to keep automobile hood in open positions during the regular maintenances or repairs. Moreover, some effort is required to open or close automobile hood because of its weight.

Scaling Sparse Constrained Nonlinear Problems for Iterative Solvers [PDF]

We look at scaling a nonlinear optimization problem for iterative solvers that use at least first derivatives. These derivatives are either computed analytically or by differncing.

Least Squares Fitting of Chacón-Gielis Curves by the Particle Swarm Method of Optimization [PDF]

Ricardo Chacón generalized Johan Gielis's superformula by introducing elliptic functions in place of trigonometric functions. In this paper an attempt has been made to fit the Chacón-Gielis curves (modified by various functions) to simulated data by the ...

Dirac‐Source Linear X‐Ray Detection Diode

Advanced Functional Materials, EarlyView.
Monolayer graphene imparts near linear current‐voltage behavior to a perovskite X‐ray detection diode, contrasting with conventional diode‐like responses. Exploiting graphene's Dirac dispersion and a Schottky‐like back‐to‐back junction, the device achieves six‐orders‐of‐magnitude dark current suppression while retaining linearity over 200 V, enabling ...

Reservoir‐Driven Neuromorphic Computing Based on Composite Rare‐Earth/Transition Metal Oxide Memristor

Advanced Functional Materials, EarlyView.
A defect‐engineered Ag/Gd2O3:Nb2O5/Pt rare earth composite oxide memristor enables stable multilevel reservoir states through pulse driven conductance modulation. Experimentally measured device responses are incorporated into a device aware reservoir computing framework for CIFAR‐100 image classification, highlighting the potential of rare earth ...
