Steering systems with an electromechanical amplifier (EMA) are a modern design solution compared to hydraulic and electro-hydraulic steering systems. Hydraulic steering amplifiers are used in the steering drives of modern trolleybuses and electric buses. If an electric motor powered from the power grid is used to drive the hydraulic pump in trolleybuses, then in electric buses, the source of electrical power is rechargeable batteries. Energy consumption to ensure the operation of the hydraulic power steering reduces the mileage of the electric bus between charging the batteries.

An approach for automating the monitoring and analysis of incoming network traffic in large-scale computer networks is proposed in the paper. The authors suggest using the Linux Berkeley Packet Filter tool to automate traffic analysis in computer networks. The software structure is developed, which includes two main parts: the service machine and the user machine, it is based on the modular principle, which allows for rapid improvement and modernization of the system.

Automobile manufacturers, when designing new cars, are increasingly faced with the need to reduce the weight of components in order to achieve the required level of fuel consumption and environmental standards. As a result, internal combustion engines (ICEs) with a small number of cylinders are designed and manufactured, which allows to achieve an increase in output power due to increased pressure in the cylinder and more efficient fuel combustion.

Modern high-torque low-speed internal combustion engines (ICEs) generate torsional vibrations close in disturbance frequency to gearboxes natural oscillation frequencies. Effective absorption of such oscillations requires a new torsional vibration damper between the internal combustion engine and gearbox design, which is implemented in the form of a dual-mass flywheel (DMF). One of the main reasons for DMF failure is its spring components destruction.

Noise immunity is one of the essential characteristics of modern wireless data reception/transmission systems. In wireless systems such as Wi-Fi, HiperLan, or Bluetooth, the signal is propagated by electromagnetic oscillations in the environment. However, unlike wiring systems, these oscillations are unprotected from external influences. Noise immunity is one of the essential characteristics of modern wireless data reception/transmission systems.

Simulation model of the mechanical component of the fully differential capacitive MEMS accelerometer has been developed using MATLAB/Simulink environment. The model allows to simulate movement of the proof mass, capacitance changes of the sense capacitors of the sensitive element, sensitivity of the sensor depending on the applied force of acceleration, and to perform the transient analysis of the integrated device at the system level of computeraided design.

In this paper the possibility of increasing quality of service for mobile operator based on using of Unlicensed Mobile Access-Advanced (UMA-A) technology has been substantiated. It has been proposed a new way of increasing the efficiency of resources allocation of convergent network. The use of UMA-A allows releasing part of the radio channel resources in the places where overloads are observed.

The logistics aspects of medical institution have been considered. Approach’s classification of simulation model’s creation of inner and external logistics has been formed. The medical institution’s simulation model of inner and external logistics structuring has been realized. The parameters’ of simulation model’s forming have been determined. The two fundamentally different approaches to simulation model’s forming according to specific character of posed tasks have been suggested. The scheme of receiving, transformation and data’s output for simulation model’s creation was developed.

This paper deals with questions of construction of mathematical and simulation models of optimal placement of objects, formalization of tasks and building placement algorithm solving problems of optimum allocation of objects by simulation.
