This paper provides a new optimization algorithm named as tunicate swarm naked mole-rat (TSNMRA) which uses hybridization concept of (TSA) and (NMRA). newly developed the characteristics both algorithms (TSA NMRA) enhance exploration abilities NMRA. Apart from concept, important parameter NMRA such mating factor is made to be self-adaptive with help simulated annealing mutation operator there no need define its value manually. For evaluating working capabilities proposed TSNMRA, it tested for 100-digit challenge (CEC 2019) test problems real multi-level image segmentation problem. From results obtained CEC 2019 problems, can seen that TSNMRA performs well compared original TSA In case problem, comparison performed multi-threshold electro magnetism-like (MTEMO), particle (PSO), genetic (GA), bacterial foraging (BF) found superior TSNMRA.

Abstract The urban air mobility market is expected to grow constantly due the increased interest in new forms of transportation. Managing aerial vehicles fleets, dependent on rising technologies such as artificial intelligence and automated ground control stations, will require a solid uninterrupted connection complete their trajectories. A path planner based evolutionary algorithms find most suitable route has been previously proposed by authors. Herein, we propose using particle swarm hybrid optimisation instead this work. goal speeding planning process reducing computational costs achieved direct search algorithms. This improved efficiently explores space proposes trajectory according its predetermined goals: maximum air-to-ground quality, availability, flight time. proposal tested different situations, including diverse terrain conditions for various channel behaviours no-fly zones.

Segmentation of wound images is important for efficient treatment so that appropriate methods can be recommended quickly. Wound measurement, subjective an overall assessment. The establishment a high-performance automatic segmentation system great importance care. use machine learning will make performing with high performance possible. Great success achieved deep learning, which sub-branch and has been used in the analysis recently (classification, segmentation, etc.). In this study, pressure was discussed different encoder-decoder based models. All are implemented on Medetec image dataset. experiments, FCN, PSP, UNet, SegNet DeepLabV3 architectures were five-fold cross-validation. Performances models measured experiments it demonstrated most successful architecture MobileNet-UNet 99.67% accuracy.
