This paper shows an experimental study about a mechanical vibration analysis technique that can be useful for monitoring mobile rotary systems in order to find a way to characterize critical parts of the system, and by this mean to create the possibility to assure its proper function. A passenger car has been used to develop a test that consisted of using a sensor to acquire the vibrations on an specific point of the car followed by the extraction of the most significant frequency harmonics in terms of amplitude, then we looked up for the relationship between the harmonics and the mechanical elements of the vehicle based on the fact that each harmonic represents a source of vibration. Using a low complexity acquisition system and a virtual instrument, the main purpose of this technique is to achieve a simple development and potentiality to assure vehicle reliability.

On up-to-date aircrafts the electric power system is a very complex and crucial system, since great part of the equipment requires power supply. Its protection is a critical task as a fault may be catastrophic if it is not quickly detected and isolated. Thermal magnetic breakers or fuses are commonly employed to provide overload and short circuit protection. Unfortunately they are not effective in detecting other dangerous faults such as electrical arcs. In the last decades many systems able to detect series and parallel arcs have been developed. Most of them are complex devices that involve custom hardware and high computational burden. In this paper the authors propose a method for the identification of the series arcs in DC power systems which is based on a simple analysis of the current signal and on the evaluation of the energy related to the arc itself. In the paper the developed technique and the related experimental results are presented.

The systematic bias error of the non-parametric frequency estimation due to leakage effect can be effective reduced by the interpolated discrete Fourier transform. For fast decline of the long-range leakages the Rife-Vincent windows are used and the RV class II windows perform the lowest bias error.

The pulse signal can reflect the change of mechanisms and pathophysiology in the blood and viscera. An integrated approach, which combines the wavelet packet transform (WPT) with hidden Markov models (HMM), is presented to analyze the pulse signals, which often exhibit non-stationarity, in this study. Specifically, pulse signals measured from healthy and hypertensive subjects were decomposed into a number of frequency sub-bands, and energy features were then extracted from these sub-bands. The key features associated with each sub-band were selected based on the Fisher linear discriminant criterion. The key features were subsequently used as inputs to a HMM classifier for assessing the subjects' health status. Experimental results indicate that the proposed approach can differentiate the hypertensive pulses from healthy pulses effectively.

The deeper interconnection and the increasing presence of active devices on the electrical networks is raising many issues concerning with the monitoring of Power Quality phenomena. Voltage parameters related to the supply of electricity and current parameters related to the working of electrical apparatuses have to be monitored as accurately as possible. To this aim specific international standards impose strict measurement methods and complex measurement instrument architectures, usually based on the computation of real time Fast Fourier Transforms, to be adopted for the purpose. In particular, considering poly-phase systems, four currents and four voltages have to be detected, synchronized, measured and analyzed with good accuracy and spectral resolution. This imposes to the measurement the calculation of eight FFTs in a very short time. These requirements conflicts with the need of cost-effective measurement instruments required by spread and distributed monitoring systems in many points of the electrical plant. To face this issues this paper proposes the study and the tuning of compressive sampling (CS) techniques capable of assuring reliable reconstruction of the signal of interest from very low acquired samples. In particular, to make the CS use more feasible, the authors have also exploited some peculiarities of the CS approach in order to reduce the computational burden usually associated with the mere application of its acquisition and reconstruction protocol. Preliminary results confirm the applicability of the proposed solution.

Multiband signal is a typical signal in the realm of modern communication, whose spectrum is the sum of several narrow band signals in frequency domain. Modulated Wideband Converter (MWC) system, which is based on the emerging theory of Compressed Sensing (CS), can sample multiband signals at a sub-Nyquist rate without carrier frequencies as a precondition. In this paper, a novel recovery strategy for MWC is proposed, exploiting Simultaneous Smoothed ℓ0 Norm (SL0), to reconstruct original signal from sub-Nyquist sampling data. This method approximates ℓ0 norm using a continuous function, which can improve the reconstruction accuracy. Simulation results demonstrate that the proposed algorithm is superior to the original Simultaneous Orthogonal Matching Pursuit (SOMP) algorithm.

A design methodology for a self-priming PMMA valveless piezoelectric micro-pump has been proposed. A finite element-based software has been used to investigate the feasible device configurations. Both actuator and diffuser parameters have been studied. The experimental tests have shown that the proposed design approach yielded a low-cost and highly efficiency micro-pump.

Modeling and analysis of the functioning of power systems is very difficult because of time varying and non-linear behaviors. Often power systems are described trough simplified approaches. The most widespread one recognizes load conditions that can be considered stationary within limited time intervals, in order to apply thus standard harmonic analysis techniques. Here a data segmentation approach to distinguish the time intervals in which stationary load conditions can be recognized is discussed and assessed.

Measurement of human physical activity (PA) is important for assessing the health state. A wireless multi-sensor integrated measurement system (WIMS) has been designed for measurement of the activity types and intensities of human subjects under free-living conditions. To address challenges posted by the limited battery life and asynchronous data among multiple sensors in the WIMS system, a ZigBee-based wireless platform has been designed, prototyped, and experimentally evaluated. Multi-Data-Packaging and Slot-Data-Synchronization algorithms have been developed improved energy efficiency. Experiments have shown that the design enables continued operation of the wearable system for over 30 hours, with data synchronization error among the various sensor nodes being less than 6 ms. The results demonstrate the effectiveness of the energy-efficient wireless design for human physical activity monitoring.
