The purpose of this special edition is to develop, share the knowledge and experience in mechanical vibrations, to know the theory of the vibration, to identify the basic elements of a system of vibration and the resulting of movements; to know the applications of the analysis of diagnostic vibrations of equipment with defects and of the techniques of equilibrium; to get contact with test of vibration in instruments, rotor unbalance, apply insulation techniques and devices; to present the fundamentals and problems of mechanical vibrations of discrete systems with one or many degrees of freedom and of continuous systems, with applications in the measurement and analysis of vibrations of machines and structures.

Smart electromechanical systems (SEMS) used in cyber physical systems (CPhS). Cyber physical systems the ability to integrate computing, communication and storage of information, monitoring and control of the physical world objects. The main tasks in the field of theory and practice CPhS are to ensure the efficiency, reliability and safety of functioning in real time.

The purposes of the publication is to introduce the latest achievements of scientists of the Russian Academy of Sciences in the theory and practice of SEMS and development of methods for their design and simulation based on the principles of adaptability, intelligence, biomorfizma, parallel kinematics and parallelism in information processing and control computation.

The use of innovative technologies is deemed to improve the current measurement techniques in various research areas. Their relative merits in the respective fields, which require real-time, accurate and quantitative estimation of the measurands, shall be published with clear engineering motivation and problem solving requirement for the new theoretical and applied engineering development. In this special issue, we welcome the submission of novel research articles which are related to the advanced measurement techniques.

Products designing with strong computer modeling skills are in high demand in industry. Computer aided product design gives accurately generated and easily modifiable graphical representation of the product. The user can nearly view the actual product on screen, make any modifications to it, and present their ideas on screen without any prototype, especially during the early stages of the design process. Perform complex design analysis in short time. Enable allocating Geometric dimensioning and tolerance for manufacturing. Implementing Finite Elements Analysis methods the user can perform: Static, Dynamic and Natural Frequency analysis, Heat transfer analysis, Plastic analysis, Fluid flow analysis, Motion analysis, Tolerance analysis, Design optimization. Record and recall information with consistency and speed. In particular the use of Product Data Management (PDM) systems can store the whole design and processing history of a certain product, for future reuse and upgrade.
