AN OPERATIONAL IMPROVEMENT OF A-4DENVAR AND ITS APPLICATION TO THE ESTIMATION OF THE SPATIALLY VARYING BOTTOM FRICTION COEFFICIENTS OF THE M2 CONSTITUENT IN THE BOHAI AND YELLOW SEAS

The analytical four-dimensional ensemble variational (A-4DEnVar) data assimilation scheme inherits the advantages of the conventional four-dimensional variational (4D-Var) data assimilation scheme and removes the adjoint model.However, compatible operational improvements such as the reduction of the computational costs and the localization method s

The green cone-headed planthopper, Acanalonia conica (Say, 1830) (Hemiptera, Fulgoromorpha, Flatidae), m02q3ll/a apple watch is native to North America and is already found in several European countries.The species is found to occur in Bulgaria and Türkiye for the first time and is the first representative of the family Acanaloniidae in bo

Drawing on a strongly grassroots whip carbon magnum and expertise-supported development in the field of adult basic education in Austria, this paper traces the current shift to politically motivated interventions.The article is based on a methodologically triangulated case study based on interviews (part 1), review of theory (part 2), and document

In order to achieve the optimized design of a cased telescoped ammunition (CTA) interior ballistic design, a genetic algorithm was introduced into the optimal design of CTA interior ballistics with coupling the CTA interior ballistic model.Aiming at the interior ballistic characteristics of a CTA gun, the goal of CTA interior ballistic design is to
