This paper solves the internet of things (IoT) security issues by introducing a chaotic whale crow (CWC) optimization, which is integration optimization algorithm (CWOA) in search (CSA). The framework operates on two crucial aspects: one to select secure nodes, and other implement routing using selected trusted nodes. First, selection nodes performed based trust factors like direct, indirect, f...

Introduction. Dynamic Economic Emission Dispatch is the extended version of traditional economic emission dispatch problem in which ramp rate taken into account for limit generators a power network. Purpose. considered treats economy and emissions as competitive targets optimal problems, to reach solution it requires some conflict resolution. Novelty. The decision-making method solve has goal e...

The flexible job shop scheduling problem (FJSP) is an extension of the classical and one more well-known NP-hard problems. To get better global optima FJSP, a novel hybrid whale optimization algorithm (HWOA) proposed for solving in which minimizing makespan considered as objective. Firstly, uniformity extensiveness initial population distribution are increased with good point set (GPS). Secondl...

The joints running trajectory of a robot directly affects it’s working efficiency, stationarity and quality. To solve the problems slow convergence speed weak global search ability in current commonly used joint optimization algorithms, planning method based on slime mould whale algorithm (SMWOA) was researched, which could obtain within short time with low energy consumption. On basis analyses...

To solve the problems that whale optimization algorithm is easy to fall into local and slow convergence speed, improved proposed. Firstly, uses Skew Tent chaotic map initialize population, improve diversity of original population make individual position distribution whales more uniform; Secondly, nonlinear factor based on inverse incomplete ? function used balance global exploration developmen...

This project uses existing datasets to develop and apply the tracking methods. The main effort is directed toward data collected at Navy Ranges, with data from PMRF provided by S. Martin and data from AUTEC provided by D. Moretti. Other datasets that use bottom-mounted sensors are also be considered as they are available and appropriate. The main species of interest in these datasets are sperm ...

Double-observer line transect methods are becoming increasingly widespread, especially for the estimation of marine mammal abundance from aerial and shipboard surveys when detection of animals on the line is uncertain. The resulting data supplement conventional distance sampling data with two-sample mark-recapture data. Like conventional mark-recapture data, these have inherent problems for est...
