Estimation of stability condition in transportation process on the railway transport in the emergency situations

There is a short analysis of problem questions and the destabilising factors negatively influencing stability of transportation process shown in this article. Research algorithms of the transportation process stability management are given. The mathematical model is developed for accounting stability degree in transportation process in different parts of railways in emergency situations.

Estimation of radiating conditions on railway enterprices in the Far East region after underground nuclear explosions

Radiological consequences after underground nuclear explosions for population of the Far East region including railway workers are considered/ It is noticed that at the analysis of radiation conditions in the region after underground nuclear explosions in it, it is necessary to take into consideration the long period of relaxation, because postshocking consequences can create a mode of pulsation compression that gives an increasing effective share of radiation for railway workers in basements and on the ground floors of buildings.

Geological and climatic influence on transport tunnel stability at seismic explosive influences

The method of final elements gives a solution in the interaction of a seismic explosive wave with a ditch and underground structure in laminated non-uniform elastic sticky geometrically nonlinear soil. Accounts established the sufficient effect of seasonal changes in physical and mechanical characteristics of soil on structure durability at seismic explosive impact.

Electric power quality in lines "two wires-a rail"

The numeral and analytical analysis of a contact network influence on the level of the maximum harmonics in lines "two wires-a rail" was conducted. It is shown that electric energy quality used by consumers from lines "two wires - a rail" largely depends on a power supply circuit in intersubstational zones.

The account of financial investments in securities

Security tradings are investments for getting greater income. But investment of capital is always accompanied by commercial risk of economic losses. The ability to evaluate these losses and to some extent to expect possible negative consequences - this is the major problem for experts of organizations. The purpose of the given article is to state consistently the reflexion order of operations under the accounts of financial investments in securities.
