The Mélange of Innovation and Tradition in Maltese Law: The Essence of the Maltese Mix?

Aim of this paper is to provide valuable insights into the Maltese legal system with a special focus on private law. The assumption is that this legal system is the by-product of the "mixing" of innovation and tradition, resulting from the interaction of English law and continental law. A major role in the development of the system is played by courts. Some examples (moral damages and pre-contractual liability) are considered which highlight the importance of the function displayed by Maltese judges

A Measurement Tool for Investigating the Volcanic Activity

Video surveillance systems are consolidated techniques for monitoring eruptive phenomena in volcanic areas. Along with these systems, which use standard video cameras, people working in this field sometimes make use of infrared cameras providing useful information about the thermal evolution of eruptions. Real-time analysis of the acquired frames is required along with image storing to analyze and classify the activity of volcanoes. Human efforts are hence required to perform monitoring tasks. In this paper a new strategy is presented, which aims to improve the performance of surveillance systems in terms of human-independent image processing. The proposed methodology is based on real time thermo graphic analysis of the area considered. The tool developed provides information about the activity being monitored

A Measurement Tool for Investigating Cooling Lava Properties

This paper presents the development and uncertainty characterization of a system for the direct measurement of heat transfer in cooling lava. The system continuously measures the parameters involved in the cooling process and, particularly, in the formation of the crust. The aim is to allow the future development of a physical model of the cooling process itself. In order to realize a system that will be effective in such a hostile environment, the principles on which the instruments for radiation thermometry are based have been thoroughly investigated. A virtual instrument has been developed, interfacing the measuring system and the user, processing the incoming data, and producing an estimate of the uncertainty of the measurement chain. The various sources of uncertainty have been taken into account to produce an accurate estimate of the uncertainty associated with the measured data. The results of experimental tests are presented

A Low Cost Multi-sensor Strategy for Early Warning in Structural Monitoring Exploiting a Wavelet Multiresolution Paradigm

AbstractThis paper deals with a novel approach to validate alerts provided by an early warning system (EWS) for structural monitoring implemented through low cost multi-sensor nodes. In particular, a dedicated wavelet multiresolution methodology is presented to implement a reliable assessment of the structural behavior. Such strategy allows to discriminate the structural response to seismic sources from other exogenous inertial components. Results obtained demonstrate the suitability of the proposed solution in the framework of the development of low cost multi-sensor strategies for the early warning of anomalous structural behaviors

RTD Fluxgate behavioral model for circuit simulation

Abstract SPICE simulation is universally recognized as a powerful tool in the field of electronic engineering. Simulations are strategic when dealing with a strong non-linear behavior that cannot be easily handled analytically. Magnetic hysteresis is one example of non-linearity that founds many practical applications, especially in the field of magnetometers and magnetic sensors. The aim of this paper is to present a behavioral model of RTD Fluxgate magnetometers easy to implement and adaptive with respect to the dynamic of the driving signal. Even if the whole work is focused on a specific magnetometer, the developed methodology can generalized to the wide class of hysteretic devices

Smart virtual sensors for real-time assessment of Volcanic activity

Monitoring is mandatory in hazardous areas with active volcanoes. South Italy countries are seriously affected by continuous risk of volcanic ash emissions, explosions and eruptions. In particular, Mt. Etna and Stromboli volcanoes requires great efforts by the scientific community to develop efficient monitoring systems. Several tasks in surveillance are already being managed by authority; anyway, innovative techniques are required to improve the performance of the monitoring task which is mandatory to improve the quality of public safety. Synergy between competence on geophysical and engineer disciplines must be reinforced to develop monitoring systems aimed to increase information needed to promptly manage crisis arising from volcanic activities. In this paper an innovative monitoring system is proposed. The system is based on smart virtual sensors, which assures real-time management of the volcanic activity by providing a large amount of information on the time evolution of the observed phenomena. The system performs in two parallel tasks: the first aims to optimise the amount of the recorded data by a smart real-time processing of the gathered images and gives very rough set of information on the ongoing events (explosions, eruptions, ash emissions, etc.), while the second task is aimed to a deep analysis of the recorded data to compute statistic indexes characterizing the evolution of the volcanic activity observed (area, height, width, aspect ratio, magma flow rate, etc.). The prototype of the proposed system is composed by a thermal camera sensor and a PC-based environment for data analysis. In particular, two computation tools were developed in the LabVIEW environment which provide the above mentioned information on the ongoing activity along with a smart processing of the acquired data. The system will be aimed to give useful information to the surveillance authority which, on the basis of the obtained results, can suitably manage the incoming events
