INVERSE FILTERING FOR FREQUENCY IDENTIFICATION OF BRIDGES USING SMARTPHONES IN PASSING VEHICLES: FUNDAMENTAL DEVELOPMENTS AND LABORATORY VERIFICATIONS

This paper puts forward a novel methodology of employing inverse filtering technique to extract bridge features from acceleration signals recorded on passing vehicles using smartphones.Since the vibration of a vehicle moving on a bridge will be affected by various features related to the vehicle, such as suspension and speed, this study focuses on

Objective: To explore the phytochemical constituents from petroleum ether and dichloromethane extracts of Moringa oleifera (M.oleifera) roots using GC/GC-MS.Methods: A total of 5.11 kg fresh and undried crushed root of M.oleifera were Nettle Leaf cut into small pieces and extracted with petroleum ether and dichloromethane (20 L each) at room temper

Vocal tract length is highly variable across speakers and determines many aspects of the acoustic speech signal, making it an essential parameter to consider for explaining behavioral variability.A method for accurate estimation of vocal tract length from formant frequencies would afford normalization of interspeaker variability and facilitate acou

Ensuring service continuity has become a fundamental issue for companies involved in electricity distribution; in particular, isolating the smallest possible portion of the network as a result of faults has long been a primary objective.To this aim, solutions based on logic selectivity have been defined and implemented for an efficient search for t

During the last decade, migration flows have greatly affected the Italian economy and demography.The trend is growing, not only because of the ideal geographic position for transit, but also due to the Italian economic structure, and business interest: Cheap labour is greatly in demand among employers.The increasing number of migrants has created a
