Abstract In a streaming environment, the characteristics and labels of instances may change over time, forming concept drifts.Previous studies on data stream learning generally assume that the true label of each instance is available or easily obtained, which is impractical in many real-world applications due to expensive time and labor costs for l
Parts of the Ogun River basin namely Mokoloki, Brewery, Akomoje, Akin Olugbade, Lafenwa, Oyan, Arakanga, and Kara were surveyed to determine the effects of bedrock metals on the water quality of the river.Physicochemical analyses were done on the bedrock and water samples obtained while bedrock trace metal analyses were determined using the Tv Stan
Purpose.The article considers definition of the bond types occurring in a modified cement concrete matrix, and the evaluation of the quality of these links in a non-uniform material to determine the geometrical and physical relationships between the structure and the cement matrix modifiers.Methodology.To achieve this purpose the studies covered th
The present study concerns the experimental investigation of foamed concretes with 1600 kg/m3 density that incorporate biochar additions in the mix.A series of small notched beams are prepared to determine the fracture energy in CMOD (crack mouth opening displacement) mode and the mechanical properties in terms of flexural and compressive strength.
