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 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.

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.

This paper presents a new neuroimmune-based method for block recognition of railway rolling stock inventory numbers. The advantage of such approach is  classification without using of negative samples. Developed technique combines segmentation and classification that allows to achieve higher noise robustness, segmentation possibility of fuzzy combined digits which have different fonts and typeface, and invariance of existing numbers to scale changes. Proposed method allows to constantly increase the training set for the improvement in classification accuracy by new committee classifiers statistics due to the data reduction property achieved by using the immune clustering mechanism. Research results were implemented in the software system of automatic recognition of cars numbers (ARNV), which is operated on the JSC Russian Railways.
