MATHEMATICAL MODEL OF WORKING CAPACITY AUTOMOTIVE ALTERNATOR ^{[№ 4 ' 2015]}
Maintenance operation of modern cars does not assume diagnosing of parameters of the automotive alternator, therefore, the exit it out of operation, as a rule, is sudden, and leads to essential losses of time. Lack of techniques of an assessment of a functioning state complicates timely failure detection of alternators; therefore, the purpose of work is establishment of interrelation between structural parameters of basic elements of the alternator with its diagnostic parameters. Based on the developed mathematical models the author proves direct dependence between structural parameters of stator windings and a rotor, the rectifier block and brush-holder and parameters of their working capacity. It is established that these structural parameters are electric resistance of windings, case and interturn isolation, semiconductor diodes and a site a brush-holder — an armature coil. The conducted researches allowed to prove quantitatively the ranges of electric resistance corresponding to operating state and characteristic failures of elements of the alternator. As the automotive alternator possesses the consecutive scheme of reliability, changes of above-mentioned electric resistance by all means will lead to violation of the size (form) of its output voltage, as critical diagnostic parameter. Therefore, the solution of a problem of forecasting of operability of the automotive alternator possibly at establishment of dependence between quantitative values of electric resistance of its elements and size (form) of an output voltage which can be estimated by means of an oscilloscope.

JUSTIFICATION OF AUTOMOBILE GENERATOR SETTINGS DIAGNOSTIC PARAMETERS ^{[№ 10 ' 2014]}
Justification of the diagnostic parameters characterizing operability of automobile generating installation is given in article. Interaction of structural and diagnostic parameters is considered and the range of structural parameters values which excess conducts to change of diagnostic parameter is established. It is offered to estimate a condition of generating installation in size of scope of output tension.

ON REDUCTION OF DELAYS TO TRANSPORT IN THE AREA OF PEDESTRIAN CROSSINGS (FOR EXAMPLE, ORENBURG) ^{[№ 10 ' 2011]}
The article describes the results of the study on the nature of the traffic and transport delays in land area for pedestrian crossings in Orenburg. The authors identified characteristics indicating that the location of a pedestrian crossing on the highway-road network objects directly affects the amount of traffic delays. The authors concluded that the choice of organizational-technical actions, taking into account the location of the pedestrian crossings will help decongest the highway-road network of the city and to improve road safety.
