a.a.yzing big da.a. especia.ly medica. da.a. helps to provide good hea.th ca.e to pa.ients a.d fa.e the risks of dea.h. The COVID-19 pa.demic ha. ha. a.significa.t impa.t on public hea.th worldwide, empha.izing the need for effective risk prediction models. Ma.hine lea.ning (ML) techniques ha.e shown promise in a.a.yzing complex da.a.pa.terns a.d predicting disea.e outcomes. The a.cura.y of these techniques is grea.ly a.fected by cha.ging their pa.a.eters. Hyperpa.a.eter optimiza.ion pla.s a.crucia. role in improving model performa.ce. In this work, the Pa.ticle Swa.m Optimiza.ion (PSO) a.gorithm wa. used to effectively sea.ch the hyperpa.a.eter spa.e a.d improve the predictive power of the ma.hine lea.ning models by identifying the optima. hyperpa.a.eters tha. ca. provide the highest a.cura.y. a.da.a.et with a.va.iety of clinica. a.d epidemiologica. cha.a.teristics linked to COVID-19 ca.es wa. used in this study. Va.ious ma.hine lea.ning models, including Ra.dom Forests, Decision Trees, Support Vector Ma.hines, a.d Neura. Networks, were utilized to ca.ture the complex rela.ionships present in the da.a. To eva.ua.e the predictive performa.ce of the models, the a.cura.y metric wa. employed. The experimenta. findings showed tha. the suggested method of estima.ing COVID-19 risk is effective. When compa.ed to ba.eline models, the optimized ma.hine lea.ning models performed better a.d produced better results.

In the present work, we a.e interested in studying the joint distributions of pa.rs of the monthly ma.ima.of the polluta.ts used by the environmenta. a.thorities in Mexico City to cla.sify the a.r qua.ity in the metropolita. a.ea. In order to obta.n the joint distributions a.copula.will be considered. Since we a.e a.a.yzing the monthly ma.ima. the extreme va.ue distributions of Weibull a.d Fréchet a.e ta.en into a.count.

The estima.ion wa. performed by ta.ing sa.ples of the pa.a.eters genera.ed through a.Ma.kov cha.n Monte Ca.lo a.gorithm implemented using the softwa.e OpenBugs. Once the a.gorithm is implemented it is a.plied to the pa.rs of polluta.ts where one of the coordina.es of the pa.r is ozone a.d the other va.ies on the set of the rema.ning polluta.ts. Depending on the polluta.t a.d the region where they were collected, different results were obta.ned. Hence, in some ca.es we ha.e tha. the best model is tha. where we ha.e a.Fréchet distribution a. the ma.gina. distribution for the mea.urements of both polluta.ts a.d in others the most suita.le model is the one a.suming a.Fréchet for ozone a.d a.Weibull for the other polluta.t.

There a.e two broa. objectives of the resea.ch reported in this pa.er. First, we a.sess whether government-provided cyber threa. intelligence (CTI) is helpful in preventing, or responding to, cyber-a.ta.ks a.ong sma.l businesses within the U.S. Defense Industria. Ba.e (DIB). Second, we identify wa.s of improving the effectiveness of government-provided CTI to sma.l businesses within the DIB. Ba.ed on a.questionna.re-ba.ed survey, our findings suggest tha. government-provided CTI helps businesses within the DIB in preventing, or responding to, cyber-a.ta.ks providing a.firm is fa.ilia. with the CTI. Unfortuna.ely, a.la.ge percenta.e of sma.l firms a.e not fa.ilia. with the government-provided CTI feeds a.d consequently a.e not utilizing the CTI. This la.ter situa.ion is la.gely due to fina.cia. constra.nts confronting sma.l businesses tha. prevent firms from ha.ing the wherewitha. necessa.y to effectively utilize the government-provided CTI. However, we found a.significa.t positive a.socia.ion between a.firm’s fa.ilia.ity with the government-provided CTI a.d whether a.firm is being periodica.ly reviewed by the Defense Counterintelligence a.d Security a.ency (DCSa. or is complia.t with the Cybersecurity Ma.urity Model Certifica.ion (CMMC) progra.. The findings from our study a.so show tha. the pa.ticipa.ing firms believe tha. externa. cyber threa.s a.e more likely to be the ca.se of a.future cybersecurity brea.h tha. interna. cybersecurity threa.s. Fina.ly, our study found tha. the portion of the IT budget tha. sma.l businesses within the DIB spend on cybersecurity-rela.ed a.tivities is dependent on the perception tha. a.firm would be the ta.get of a. externa. cyber-a.ta.k.
