Today’s trend of electronics complicating makes developers to create more complex devices in a shorter time. Developers have to contrive different ways of designing automatization to prevent production worsening. However, automatization cannot improve the situation when an innovative device is developing because such developing involves a lot of testing and researches. In this article authors propose to use hardware in the loop simulation methods to optimize designing process. Hardware in the loop simulation is division the device in functional blocks, some of them are produced as models and other are produced as hardware. Usage of this method decrease cost of modernization hardware blocks and allow using a number of data processing algorithms at the same time.
The article contains a using of hardware in the loop actuality description, main steps of designing enunciation and description of method exemplified by designing of data-measuring and controlling system for automatic orientation of tropospheric communications station.

In article the material about use of interactive training programs in educational process of the students training difficult household appliances is prepared. 
Within transition of the higher educational school to provisions of Bologna Process by a leading method of pedagogical work there is a competence-based approach to formation of steady knowledge and practical skills at students [1]. Indispensable condition thus is compliance of quality of training and the general education standard. As especially important requirement continuous control of assimilation of educational information and ability of its application serves in practical activities. The most well-tried remedy of total control of assimilation of educational information is carrying out daily testing, including remote. Use of test interactive programs becomes more actual at integration of groups and increase of an academic load on the teacher [2].

The problem of justifying extending the service life of hydraulic structures in Russia is unsatisfactory condition requiring modernization and refurbishment. Currently in Russia over the length of the river network of 2.37 million sq km includes more than 125 thousand rivers that can be used for navigation. When locking, the most widely found as regulator control structures of low pressure shield dam spillways with metal swivel farms most widely used when evaluating the residual life of structural elements carrying water conveyance structures, has an integrated risk assessment of the accident. According to the distribution curves can be classified technical condition of each item, such as rods and plates in various defects as small and dangerous damage the elements included in the design. During the simulation obtained contour plots of stress-bearing low-pressure water-lifting precast shield dams for subsequent prediction justify continued reliable exploitation. The concept of life extension studies supporting structures prefabricated low-pressure water-lifting shield dams on the example of individual structures bearing elements, prefabricated low-pressure water-lifting shield dams, based on modeling of the loading process from various defects and damage due to prolonged use.

Keywords: water-conducting structures, prefabricated pumping low-pressure-mounted dam, modeling, technical condition, residual life.

A stability problem of milling process is under consideration. A novel analytical tool is presented to assess the optimal cutting parameters which provide a chatter free machining. Chatter instability is broadly studied in the literature. However, the problem of simultaneous optimization of radial and axial depths of cut is kept out of scope. To describe the optimization method a single-degree-of-freedom model of milling process is investigated as well as corresponding equation of motion and function of cutting force. A unified delay-differential equation is proposed. A theorem of asymptotic stability is suggested. Suggested optimization technique allows to create a diagram of radial and axial depth-of-cut dependence.  As shown, there exists an extremum of function of axial and radial depth-of-cut dependence.

With the growing fleet's increasingly acute problem arises safety and reliability their exploitation as a result of this increase in productivity and accuracy of their technical diagnostics. Urgent task to further improve diagnosis for vehicles is to develop new methods and algorithms highlight the dominant component of the information in relation to a wide class of vehicles. The methods joint time-frequency and wavelet analysis. To isolate the dominant component of the information proposed to use the method of wavelet decomposition. Using vibro acoustic registration nodes vehicles funds allowed to receive signals carrying information about the defects of individual units of vehicles. The proposed decoding algorithms signals have high reliability, allow technical inspection, subsequent monitoring of the technical state of the vehicle.
