This paper proposes an improved step detection approach for smartphones. The improvements consist in a new fuzzy-logic (FL) algorithm for user’s step detection using accelerometer data. The proposed method exploits ranges of features reported in reference data on basic gait parameters. We also formulate robust defuzzification-rules related to future(More)
Nitrate contamination still remains one of the main groundwater quality issues in several aquifers worldwide, despite the perduring efforts of the international scientific community to effectively tackle this problem. The classical hydrogeological and isotopic investigations are obviously of paramount importance for the characterization of contaminant(More)
