Social and economic development trends require that the economy be based on sustainable consumption and sustainable production patterns by means of implementing an effective recirculation policy – this is also important from an environmental perspective. Consequently, the design of economic processes becomes increasingly complex. This paper presents method and results of environmental life-cycle assessment of selected stages of the concrete recycling process. The results will be used in a further, holistic assessment of managing the concrete waste on the construction site.

https://doi.org/10.4467/20838476SI.15.006.3028In this article we present the use of sparse representation of a signal and incoherent dictionary learning method for the purpose of network traffic analysis. In learning process we use 1D INK-SVD algorithm to detect proper dictionary structure. Anomaly detection is realized by parameter estimation of the analyzed signal and its comparative analysis to network traffic profiles. Efficiency of our method is examined with the use of extended set of test traces from real network traffic. Received experimental results confirm effectiveness of the presented method.
