Falls are critical events among elderly people that requires timely rescue. In this paper, we propose a fall detection system consisting of an inertial unit includes triaxial accelerometer, gyroscope, and magnetometer with efficient data fusion algorithms. Starting from the raw data, implemented orientation filter provides correct subject in terms yaw, pitch, roll angles. The is tested according to experimental protocols, engaging volunteers who performed simulated falls, falls recovery,...

Accurate flood forecasting is essential to mitigate the impacts of extreme rainfall on communities and infrastructure. Traditional hydrological prediction methods often rely rain gauge data numerical models, which can be limited in capturing precipitation's spatial temporal dynamics, particularly during intense or rapid-onset events. X-band polarimetric radar provides a valuable alternative for quantitative estimation, offering finer resolution crucial applications.This study investigates...

In this study, we propose a method based on support vector regression (SVR) to model the nonlinear dynamics of customer load demand given limited set previous measurements. Such methodology is used for short-term forecasting (STLF). SVR trained and tested using real-world data from both residential business profile types. An important issue in addressed: determining single kernel parameters suitable whole year, regardless type. Main advantages proposed are that makes no prior assumptions...

An aspect correlated with climate change is certainly represented by the alternation of severe floods and relevant drought periods. Moreover, there evidence that changes in land cover are inducing stream channel cross-sections, altering local capacity. A direct consequence a significant capacity relationship between amount water flowing at given point river or (usually gauging stations) corresponding stage section, known as stage-discharge rating curve, changed. The key messages deriving...

A wireless sensor network (WSN) consists of spatially distributed autonomous nodes (sensors) to cooperatively monitor environmental or physical conditions. The considerable reduction in size and energy consumption CMOS circuitry together with the self-organizational capability are leading WSNs be ubiquitous. operate under very strict constraints power supply is usually most expensive component node being designed. This study proposes a methodology reduce by means an energy-efficient...

Replacing a portion of current light-duty vehicles (LDVs) with plug-in hybrid electric (PHEVs) offers the possibility to reduce dependence on fossil fuels together environmental and economic benefits. However, charging myriad PHEVs will certainly introduce huge new load power grid. In framework development smarter grid, primary focus present study is propose model for daily electrical demand from residential sector in presence PHEVs. The expected PHEV modeled by assigning certain probability...

Divers’ health state after underwater activity can be assessed the immersion using precordial echo Doppler examination. An audio analysis of acquired signals is performed by specialist doctors to detect circulating gas bubbles in vascular system and evaluate decompression sickness risk. Since on-site medical assistance cannot always guaranteed, we propose a for automatic emboli detection custom portable device connected instrument. The empirical mode decomposition method used develop...

In the framework of three projects co-funded by European Union (EU), an X-band (8-12 GHz frequency range) polarimetric radar was installed in Marche Region territory (East-Central Italy) at Cingoli municipality, province Macerata. The site is located about 750 m above sea level and 30 km away from Adriatic Sea. radar, managed Civil Protection Service, employed for weather monitoring purposes pre-operational stage. It known that measurements are affected various sources error, to be addressed...

In the framework of Radiation Explorer in Far InfraRed space mission for characterization far infrared Earth outgoing emission, a breadboard version Fourier transform spectrometer, which is core instrument payload package, has been developed. The spectrometer operates spectral range 100-1100 cm^-1 with resolution 0.5 cm^-1, 6.5 s acquisition time, and signal-to-noise ratio better than 100. It compact prototype designed both laboratory applications field campaigns,...

The effects of climate change are already being felt in several parts the World. Variability changing rainfall intensity, drought and weather patterns contribute to determining vulnerability many human activities such as agriculture. In next future, considerations will depend on having appropriate strategies strengthen implementation agencies working a coordinated manner with data-driven approach order ensure monitoring, reporting data verification. this context, national regional...

We propose the utilization of a satellite system, composed by couple LEO (low Earth orbit) satellites operating in 18-22 GHz range (close to 22.235 absorption line water vapor), estimate total content vapor (IWV, integrated vapor) along propagation path between two (one them carrying transmitter, other receiver). In particular, we show that IWV can be estimated starting from measurements received spectral power.

Wireless sensor networks (WSNs) are nowadays employed in several applications that require real-time event monitoring (telemedicine, remote environmental monitoring, industrial automation). This has been enabled by the availability of sensors have become smaller, cheaper, and intelligent. Most development efforts WSN design were focused on energy efficiency, dynamic self-organization mobility nodes (sensors). Providing Quality Services (QoS) support WSNs is an emerging area research due to...
