The asymptotic stability of the model's equilibrium points has been studied during the quantitative analysis of the model and Hopf bifurcation analysis has been done for the model by using Laplace transformation technique. Stability analysis is an established tool for the analysis of complex mathematical models. Numerous studies have examined the model for integer order, but none have examined the fractional-order model under the impact of time delay and done stability and Hopf bifurcation analysis for the aforesaid model. This motivates us to study the fractional-order delay love dynamical model for non-synergic couple. Here, we have considered the fractional- order time delay to represent the long-term behaviour of the model. Finally, the numerical simulations have been carried out using MATLAB to illustrate our derived results.","PeriodicalId":45487,"journal":{"name":"International Journal of Computing Science and Mathematics","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135262348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A kind of non-destructive diagnosis of KOA based on sparse coding of magnetic resonance imaging (MRI) is presented. The two-dimensional Gabor filter bank is used to extract the high-dimensional features of KOA-MRI images. Secondly, a fitness feedback particle swarm optimisation is proposed to choose three key parameters of the Gabor filter: bandwidth parameters, maximum frequency of the centre and window size. Then the extracted Gabor visual features are described by the sparse coding and sparse coefficient matrix of magnetic resonance images. An improved feature imbalance support vector machine (SVM) is used to classify magnetic resonance images by considering the unbalanced influence of feature contributions. The overall performance of diagnosis has improved.","PeriodicalId":45487,"journal":{"name":"International Journal of Computing Science and Mathematics","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135262353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the absorption of electromagnetic wave by seawater, underwater wireless communication is very difficult. In order to adapt to the complex working environment in the deep sea, it is necessary to adopt the communication system with the characteristics of non-contact, low power consumption, small size, two-way transmission and so on. In this paper, a set of underwater short distance magnetic coupling communication system equipment is developed. Combined with the parameter calculation formula of magnetic coupling coil, the short spiral coil is wound, and the experiment is carried out to simulate the seawater environment. The experimental results show that the system has the advantages of low power consumption, small volume, two-way transmission and good stability.","PeriodicalId":45487,"journal":{"name":"International Journal of Computing Science and Mathematics","volume":"42 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135636832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
