Energy Consumption Optimization in Trajectory Planning for Fuel Cell Hybrid Uavs Based On HMPC

Advanced Robotics Research, EarlyView.
The endurance limitation of multirotor drones is a critical challenge. This study adopts a hybrid power system of fuel cells and lithium‐ion batteries. Using Nondominated Sorting Genetic Algorithm II, it integrates trajectory planning with energy management optimization.

A new local path planning approach based on improved dual covariant Hamiltonian optimization for motion planning method

Advances in Mechanical Engineering, 2019
We propose a new local path planning approach based on optimization methods with probabilistic completeness in this article. This approach adds a linear constraint to the original covariant Hamiltonian optimization for motion planning problem with a new ...

Path integral of the hydrogen atom, the Jacobi's principle of least action and one-dimensional quantum gravity

, 1996
A path integral evaluation of the Green's function for the hydrogen atom initiated by Duru and Kleinert is studied by recognizing it as a special case of the general treatment of the separable Hamiltonian of Liouville-type.

DISTRIBUTED HAMILTONIAN PATH SEARCH ALGORITHM

Perner’s Contacts, 2010
Many practical problems of transportation can be transformed to the problem of finding Hamiltonian path or circle. It was proven, that this problem is NP-complete and thus can be very time-consuming for practical problem size. In this paper we present a

Proving the existence of Euclidean knight's tours on n×n×...×n chessboards for n<4 [PDF]

Notes on Number Theory and Discrete Mathematics
The Knight's Tour problem consists of finding a Hamiltonian path for the knight on a given set of points so that the knight can visit exactly once every vertex of the mentioned set. In the present, we provide a 5-dimensional alternative to the well-known

Giant Magnetocaloric Effect in a Honeycomb Spiral Spin‐Liquid Candidate

Advanced Science, EarlyView.
The frustrated honeycomb‐lattice single‐crystal GdZnPO, a spiral spin‐liquid (SSL) candidate, exhibits a giant magnetocaloric effect (with a large Grüneisen parameter Γm = 4.4 T−1) and exceptional cooling performance near the crossover magnetic field (Hc), surpassing other known magnetocaloric materials.

The number of Hamiltonian paths in a rectangular grid

Discrete Mathematics, 1997
Given a rectangular \(m\) vertex by \(n\) vertex grid, let \(f(m,n)\) be the number of Hamiltonian paths from the lower left corner (LL) to the upper right corner (UR). The paper gives a generating function which is the quotient of two polynomials, and contains the sequence \(f(m,1)\), \(f(m,2)\), \(f(m,3)\), \(f(m,4),\dots\) as the coefficients in its
