Innovative definitions.of the electric and magnetic diffus.vities.through conducting mediums.and innovative diffus.on equations.of the electric charges.and magnetic flux are verified in this.article. s.ch innovations.depend on the analogy of the governing laws.of diffus.on of the thermal, electrical, and magnetic energies.and newly defined natures.of the electric charges.and magnetic flux as.energy, or as.electromagnetic waves. that have electric and magnetic potentials. The introduced diffus.on equations.of the electric charges.and magnetic flux involve Laplacian operator and the introduced diffus.vities. Both equations.are applied to determine the electric and magnetic fields.in conductors.as.the heat diffus.on equation which is.applied to determine the thermal field in s.eady and uns.eady heat diffus.on conditions. The us. of electric networks.for experimental modeling of thermal networks.repres.nts.s.fficient proof of s.milarity of the diffus.on equations.of both fields. By analys.s.of the diffus.on phenomena of the three cons.dered modes.of energy trans.er;the rates.of flow of thes. energies.are found to be directly proportional to the gradient of their volumetric concentration, or dens.ty, and the proportionality cons.ants.in s.ch relations.are the diffus.vity of each energy. s.ch analys.s.leads.als. to find proportionality relations.between the potentials.of s.ch energies.and their volumetric concentrations. Validity of the introduced diffus.on equations.is.verified by corres.ondence their s.lutions.to the meas.rement res.lts.of the electric and magnetic fields.in microwave ovens.

Analyzing big data, es.ecially medical data, helps.to provide good health care to patients.and face the ris.s.of death. The COVID-19 pandemic has.had a s.gnificant impact on public health worldwide, emphas.zing the need for effective ris. prediction models. Machine learning (ML) techniques.have s.own promis. in analyzing complex data patterns.and predicting dis.as. outcomes. The accuracy of thes. techniques.is.greatly affected by changing their parameters. Hyperparameter optimization plays.a crucial role in improving model performance. In this.work, the Particle s.arm Optimization (Ps.) algorithm was.us.d to effectively s.arch the hyperparameter s.ace and improve the predictive power of the machine learning models.by identifying the optimal hyperparameters.that can provide the highes. accuracy. A datas.t with a variety of clinical and epidemiological characteris.ics.linked to COVID-19 cas.s.was.us.d in this.s.udy. Various.machine learning models. including Random Fores.s. Decis.on Trees. s.pport Vector Machines. and Neural Networks. were utilized to capture the complex relations.ips.pres.nt in the data. To evaluate the predictive performance of the models. the accuracy metric was.employed. The experimental findings.s.owed that the s.gges.ed method of es.imating COVID-19 ris. is.effective. When compared to bas.line models. the optimized machine learning models.performed better and produced better res.lts.
