摘要：The paper presents different phases of largeIT project creation–the simulation environment of movement and maneuvering of ships for the needs of pilot navigation systems (PNS).The particular effort was placed on new methods of object modeling with the use of UML (Unified Modeling Language),which is a standard used for proper management of the object programming development process.
其他摘要：The article considers the upgraded device to determine the thickness of lubricating films when testing the gear materials.The content of modernization of such a device includes apart from the connected in series the rolling samples of ammeter,rheostat,battery and switch as well as the voltmeter samples connected in parallel with the addi tional the rigid conductive plate and two voltmeters connected by ones of their ends between themselves and the rigid conductive plate and by the other ones with the individual samples.The mentioned above device in addition to the determining the oil film thickness and the total thickness of boundary lubricating films on the working surfaces of both roller samples pro?vides also the possibility of determining on the working surface of each sample separately.This enhances significantly its func?tional capacity for physical simulation of work conditions for closed gear trains of the printing equipment.
