1 dzień temu · Cayley Q8 graph showing the six cycles of multiplication by i, j and k. (If the image is opened in the Wikimedia Commons by clicking twice on it, cycles can be highlighted by hovering over or clicking on them.). In mathematics, the quaternion number system extends the complex numbers.Quaternions were first described by the Irish mathematician William Rowan Hamilton in 1843 and applied to ...
7 godz. temu · In this paper, we propose an innovative approach for the path planning of Uninhabited Aerial Vehicles (UAVs) that combines an advanced Genetic Algorithm (GA) for optimising missions in advance and a geometrically based obstacle avoidance algorithm (QuickNav) for avoiding obstacles along the optimised path. The proposed approach addresses the key problem of determining an optimised trajectory ...
7 godz. temu · A stroke represents a significant medical condition characterized by the sudden interruption of blood flow to the brain, leading to cellular damage or death. The impact of stroke on individuals can vary from mild impairments to severe disability. Treatment for stroke often focuses on gait rehabilitation. Notably, assessing muscle activation and kinematics patterns using electromyography (EMG ...

7 godz. temu · Satellite remote sensing has become an important means of forest fire monitoring because it has the advantages of wide coverage, few ground constraints and high dynamics. When utilizing satellites for forest fire hotspot monitoring, two types of ground hotspots, agricultural and other fire hotspots can be ruled out through ground object features. False forest fire hotspots within forested ...
7 godz. temu · Thus, we focus on the perturbation theory of TRS for the above three cases.The contributions of this work are as follows: First, suppose that the TRS is in easy case, we give a sufficient condition under which the perturbed TRS is still in easy case.Secondly, with the help of the structure of the matrix problem arising in TRS (), we perform first-order perturbation analysis on the Lagrange ...
