  • The potential of web awareness as a determinant of dually defined customer value

    Publikacja

    - TECHNOLOGICAL FORECASTING AND SOCIAL CHANGE - Rok 2021

    In the conditions of increasing demand barrier, the enterprise’s basic capital is customers. From an enterprise point of view, this means the need to create a dual perceived and defined customer value which remains related to market value (income and development potential) and customer resource value (reference, information and cooperative potential). The progressing digitisation process transfers business processes, and thus relationships, into...

  • Fluctuation-Enhanced Sensing

    Publikacja

    - Journal of Sensors - Rok 2020

    Fluctuation-enhanced sensing (FES) is an exciting and relatively new research field that promises to extend the range of information that can be extracted from a single sensor. In FES, the stochastic fluctuations of the sensor signal, rather than its average value, are recorded and analyzed. Typical components of such fluctuations are due to interactions at the microscopic level. Proper statistical analysis provides optimum sensory...
