Unerroric Automatic Control of Civil Hydroacousticer’s Working Quality on Board

Abstract

The collision of a dry cargo ship with a submarine off Cape Ashizuri this year has actualized the study of the possibility of unerroric control of readiness of passenger and merchant ships to extreme variants of hydroacoustic conditions. The purpose of the research is to develop digital methods and algorithms of automatic quality control of ship’s hydroacousticer. The possibility of such control by multilevel estimation of results within training hydroacousticer on board of the ship is investigated. Recurrent methods and algorithms of formation of final and intermediate estimations of results of such training in a training mode within functioning of on board hydroacoustic means are offered and developed. These methods and algorithms allow complicating the simulation model of hydroacoustic environment fraught with ship accidents.

Multi-criteria evaluation of reference terms requirements for development work performance

“…To minimise these risks [15][16][17][18], it is advisable to develop a methodological device that allows the head of the organisation to determine the possibility of implementing the contract conditions based on the results of a multi-criteria assessment of the requirements of the terms of reference for R&D [16], taking into account the resources available to the potential contractor and the level of personnel qualification.…”

Evaluation of the effect of interphase zone on the properties of the Al-Al2O3 composites

“…Modern composites have not only a wide spectrum of physical-mechanical properties but are also capable of their directed change, for example, to increase fracture toughness, to regulate stiffness, strength and other properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. These possibilities are extended to the application in fibre composites of various nature and geometry, that is, to the creation of hybrid composites [16][17][18][19][20][21][22][23][24][25][26][27][28]. In addition, the synergetic effect (coordinated joint action of several factors in one direction) is typical for these materials.…”
