Due to the relatively low rigidities in the vertical and horizontal planes, the structures of the footbridges must be checked from the point of view of their dynamic behavior, so as to avoid the resonance phenomenon and to ensure the walking comfort of the pedestrians. The paper presents some aspects related to the dynamic behaviour, for the pedestrian bridge with a span of 31.5 m that was constructed in The Railway Park area of Cluj-Napoca city, over the Someşul Mic River, in 2022. In terms of pedestrian traffic density, the structure falls into Category III: Footbridges for normal use occasionally crossed by large groups of pedestrians. After the finalization of the project The Revitalization and Activation of the Railway Park in Cluj-Napoca city, the park will include two pedestrian walkways with similar superstructure, which crosses the Someș River, but in the vicinity of the park a road bridge with 4 traffic lanes and two sidewalks was also built during this period. Given the possibility of changing the density of walking in the future, the footbridge was also analysed for higher density conditions, so that there is no need to carry out structural intervention works in the near future, except for known maintenance works.

This paper presents the design and implementation of an embedded system for real-time network flow identification. The system identifies data flows based on packet inspection. The main advantage of this system is that it reduces significantly the processing time required for the flow identification. For the hardware implementation, a Xilinx Virtex-II Pro FPGA device and the Xilinx Embedded Development Kit (EDK) software are used. This embedded system represents the first step for designing a reconfigurable router with QoS (Quality of Service) support.
