Compositions of fine-grained concrete mixtures that provide the minimum required strength values in 1 day (7.5 MPa) have been developed. A comparison was made of the test results of the properties of samples printed on a 3D printer with samples made acco...

Events of a seismic nature followed by catastrophic floods caused by tsunami waves (the incidence of which has increased in recent decades) have an important impact on the populations of littoral regions. On the coast of Japan and Kamchatka, it takes nea...

The correctness of the adjoint approach used in Marchuk and Skiba (1992) is demonstrated. Remarks are made on the historical development of the adjoint methods and its application in the works by Cacuci (1981), Cacuci and Schlesinger (1993), Hall (198...
