"Dynamic mode of heat exchangers is typical for a number of technological thermal plants , as well as air-heating systems , ventilation, and air conditioning. Technologically predetermined control algorithm operating mode heat exchangers in practice implemented by means of manual or automatic adjustment in one or more control parameters . Obviously, the most efficient in the energy and technically and economically dynamic mode control algorithm of the heat exchanger can be detected only in the form of a review of the relevant mathematical model. In this paper we consider a mathematical model of the dynamic operation of the system of heat exchangers with natural air circulation . As input parameters are considered the temperature of hot and cold air streams. Modeled by changing the inputs are heat exchangers and the extent to which these changes will not affect the operation of the entire system. In order to keep the temperature at the i- MOT has not changed , the coefficient of variation should tend to zero , since all the other quantities are limited by technical parameters of the system . By changing the values ​​of the input parameters is analyzed mass flow of hot flow limits are changing the output parameters of the preceding heat exchangers that will not change the entire system ."

To solve the traffic problems , namely the coordination of the movement of transport modes have been developed micro-and macro-modeling programs that predict traffic situations , to choose the most appropriate solutions for specific problems by using real data and statistics. The emergence of intelligent transportation systems, traffic simulation pushed to the fact that it has become one of the most used methods for studying the traffic flow, allowing to plan and predict the situation on the roads. The possibilities offered by the modeling of traffic flows , helping to simulate the situation on the roads, and it becomes a unique tool for understanding the complexity of transport systems. For precise work of model needs an indicator such as the time of the trip. Travel time - the time it takes to travel from one point to another , consisting of travel time and the stop time of the vehicle.

Traffic light control for urban road network has for several decades been one of the most important areas of study and application in order to ensure maximum efficiency . During this time he developed a variety of techniques and tools , a lot of research . But with the ever increasing number of cars and , as a consequence , poor road conditions and increases in the amount of traffic congestion , require more and more new and advanced techniques that would have allowed not only to solve the existing problems , but also to predict the possible developments in the future. Traffic congestion on the road network of the city continues to be a growing problem of modern cities . Possible reduction of traffic congestion can be achieved either by the constant increase in the volume of road surface, or by reducing the demand for personal vehicles . If we assume that the improvement will be achieved by increasing the number of roads , it is possible to face the fact that it is not always feasible , given the current road infrastructure . Accordingly , it follows that it is necessary to focus on the use of traffic management to reduce congestion and subsequent increase in urban transport mobility .

The composition, basic properties and application scope of the two main types of expanding binders historically most widespread in Russia such as gypsum-alumina expansive cement and expansive cement Type M are given. The expansion kinetics of the binders ranging from gypsum-alumina expansive cement to expansive cement Type M is observed. The role of lime as a supplement and as a hydration product of the Portland cement in the expansion process is shown: as a supplement in small values (2-4%) to gypsum-alumina expansive cement with higher gypsum concentration stabilizes the hardening and expansion process, in higher values boosts the expansion process to self-destruction. Optimization criteria of the expansion kinetics aimed at obtaining project expansion in 10 days of hardening without any additional chemical additives are proposed.
