The preliminary numerical simulation results obtained in the analysis of a landmine detection system based on laser excitation of acoustic -seismic waves in the soil and observing its surface vibration above the embedded landmine are presented. The presented numerical simulations comprise three main parts: 1) Laser oscillator and laser beam propagation and absorption in soil; a laser oscillator operated in Q-switched regime is considered; different laser wavelengths are investigated. 2) Acoustic -seismic wave generation by absorption in soil of laser pulse energy; 3) Evaluation of acoustic -seismic wave generation by the buried in soil landmine; 4) Comparison of Distributed FeedBack Fiber Laser (DFB-FL) and Laser Doppler Vibrometer (LDV) detector used for soil vibrations evaluation. The above mentioned numerical simulation is dedicated for evaluation of an integrated portable detection system.

In the polymeric products industry, the lean production system is perceived as a solution to reduce difficulties of manufacturing automation processes complexity while reducing used resources, eliminate losses, and increase efficiency, flexibility, and profitability. Industry 4.0 is the stage of intelligent automation that exploits the latest developments in polymeric products engineering. Through implementation of information technology and the Industry 4.0 concepts in lean manufacturing 4.0 of polymeric injection molding products is a challenge that needs a strategic approach to efficient interconnection processes. The main achievements of intelligent polymeric products manufacturing system are based on the versatility and individualization of designing and manufacturing processes. The transition from lean manufacturing to Lean 4.0 manufacturing system is a complex project that requires physical production system update, transforming lean tools, build the cyber production system, define and implement Lean 4.0 tools, and connecting them into a new integrated cyber–physical system. This paper presents a strategy for identifying the transition that can be approached within an intelligent and adaptive molding cell fabrication of polymeric products industry.
