DMPA-HHO: A Hybrid MPA-HHO optimizer with Dynamic Opposite Learning
, 2022 Abstract A new hybrid algorithm is proposed by incorporating Harris Hawks Optimization with Marine Predators algorithm and dynamic Opposition-based learning, namely DMPA-HHO. In the algorithm, the problem is addressed that Harris Hawks Optimization (HHO) tends to fall into local optima and low accuracy of the solution. Dynamic Opposite Learning

Stabilization-free HHO a posteriori error control
Numerische Mathematik, 2023 AbstractThe known a posteriori error analysis of hybrid high-order methods treats the stabilization contribution as part of the error and as part of the error estimator for an efficient and reliable error control. This paper circumvents the stabilization contribution on simplicial meshes and arrives at a stabilization-free error analysis with an ...

The Unfitted HHO Method for the Stokes Problem on Curved Domains [PDF]
, 2020 We design a hybrid high-order (HHO) method to approximate the Stokes problem on curved domains using unfitted meshes. We prove inf-sup stability and a priori estimates with optimal convergence rates. Moreover, we provide numerical simulations that corroborate the theoretical convergence rates.

Công nghệ cung cấp HHO cho động cơ xe gắn máy sinh thái được cải tạo từ xe Honda Lead 110cc
Tạp chí Khoa học và Công nghệ, 2023 Khi cung cấp HHO bằng phương pháp phun thì nồng độ cực đại của H2 còn sót lại trên đường nạp phụ thuộc vào áp suất phun và tỉ lệ HHO/không khí. Ở tốc độ động cơ 7500v/ph, với áp suất phun 5000Pa thì nồng độ cực đại của H2 còn sót lại trên đường nạp là 0 ...
