On. of the most importan. parameters in.meteorology is the mean.win. pro fi le in.the tropical cyclon. boun.ary layer.

Approximately 2,000,000 people are exposed to volcan.c risks in.commun.ties situated at the flan.s of Moun.s Cameroon.(MC) an. n.iragon.o (Mn. volcan.es in.Cen.ral Africa. This study therefore sought to in.estigate risk perception.from four previous eruption. of MC, n.mely the 1959, 1982, 1999, an. 2000 eruption.;an. two previous eruption. of Mn. 1977 an. 2002. The study was in.tiated with co-design.workshops held with major stakeholders in.the cities of Buea an. Goma at the flan.s of MC an. Mn. respectively, in.2017, to develop the research objectives for the study. A n.n.ran.om question.aire survey was later con.ucted within.14 an. 15 commun.ties in.Buea an. Goma respectively, on.the effects, perceived risks, an. copin. strategies for the chosen.eruption.. Three age groups (18 - 30, 31 - 45 an. >45 years) an. gen.er (male an. female) were con.idered. The population.at the flan.s of both volcan.es cited scien.ific an. in.igen.us factors to be respon.ible for eruption. from these volcan.es. At MC an. Mn. ≥45% of the sampled participan.s (with a higher female population. perceived that the sampled eruption. posed a very high risk to the population. In.terms of the effects, the age group of 18 - 30 was the least kn.wledgeable. In.terms of direct effect on.person., over 90% of participan.s at MC an. Mn.attested that they were overcome by fear/pan.c. On.measures to cope with an. likely eruption. the followin. order was established at the flan.s of both volcan.es: sen.itization.of population. use of religious (prayers) an. of tradition.l/in.igen.us strategies. In.terms of future copin. strategies, while the males at MC main.ain.d sen.itization.as the favourite option. 62% of the males at Mn.opted for tradition.l/in.igen.us strategies.

This paper presen.s an.approach to improve medical image retrieval， particularly for brain.tumors， by addressin. the gap between.low-level visual an. high-level perceived con.en.s in.MRI， X-ray， an.

It employs a gen.tic algorithm for feature reduction.an. a hybrid residual Un.t (HResUn.t) model for region.of-in.erest (ROI) segmen.ation.an. classification. with en.an.ed image preprocessin.. The study examin.s various loss fun.tion.， fin.in. that a hybrid loss fun.tion.yields superior results， an. the GA-HResUn.t model outperforms the HResUn.t.
