Automated Test Systems (ATSs) can join the Internet of Things (IoT) at multiple layers and benefit both the overall IoT concept as well as advance the goals of ATSs. Logistics and sustainment are traditionally brought into the IoT conversation through asset tracking, transportation, and Health and Usage Monitoring Systems (HUMS). However the IoT has additional aspects that can be related to logistics...
Increased interest in security has resulted in greater demand for automated test systems to comply with security standards. Automated test systems have traditionally been operated in isolated environments because of their unique characteristics. However, changes in United States defense acquisition regulations require that defense contractors bring these test systems into compliance with National...
Phasor Measurement Units have become more and more interesting for monitoring applications in distribution grids. For a large exploitation in medium and low voltage networks, however, a limited cost is required. Such specification, however, should not impact excessively the accuracy requirements, as it is expected that automatic control functionalities will run based on state estimation algorithms,...
Nowadays the adoption of IoT solutions is gaining high momentum in several fields, including energy, home and environment monitoring, transportation, and manufacturing. However, cybersecurity attacks to low-cost end-user devices can severely undermine the expected deployment of IoT solutions in a broad range of scenarios. To face these challenges, emerging software-based networking features can introduce...
The Phasor Measurement Unit (PMU) is a modern instrument that measures magnitude, phase angle, frequency and rate of change of frequency (ROCOF) from voltage and current signals in electric networks. It is designed to be used in the monitoring and control of electric transmission systems. For each measurement, the PMU assigns a timestamp from an accurate time source; in this way, it is possible to...
Long term monitoring of human micro activities along breathing is still considering challenging in noncontact vital sign measurements. A new detection method based on acceleration of micro-motion displacements is proposed through ultra-wideband radar. Micro motions responses due to different physiological conditions, including random body movement, coughing and speaking are quantitatively detected...
The operation and maintenance of large distributed systems that are subject to high QoS conditions has led to the need of designing and developing advanced monitoring tools that facilitate the administration of the critical services required by the user communities. RASSMon is a portable, reliable, secure software platform able to collect monitoring data from multiple sources in heterogeneous environments...
In order to assess the microshock risk, the automatic detection of currents during surgery is important. To this aim, a prototype, called Protegemed, was designed. In order to introduce the device in Italian operating rooms the compliance assessment with international standards is essential. The results of some electrical safety tests and the identification of a measuring method to detect the microshock...
Cryptographic APIs are often vulnerable to attacks that compromise sensitive cryptographic keys. In the literature we find many proposals for preventing or mitigating such attacks but they typically require to modify the API or to configure it in a way that might break existing applications. This makes it hard to adopt such proposals, especially because security APIs are often used in highly sensitive...
Agricultural drought greatly impacts the crop yield. Monitoring agricultural drought can deliver critical information to farmers on when, where and how much to irrigate. However, precisely monitoring which requires many kinds of data sources and data fusion and mining is still a huge challenge for scientists. In recent years, many data sources like remote sensed hyperspectral images are released online...
The paper deals with the behavior of a medium / low voltage transformer (MV/LV), for a non-sinusoidal consumer placed in the transformer's secondary winding. The analysis is performed using the Discrete Wavelet Transform (DWT). The monitoring is realized with two data acquisition systems, briefly described in the paper. Problems associated to the conducted and radiated emissions are addressed and...
This paper first gives a brief review of Integrated Vehicle Health Management (IVHM) concept, functions and architecture, then summarizes recent international research and development activities in this area especially in commercial aviation industry. A clear trend is that IVHM has become a focus in aerospace industry. All commercial aircraft manufacturers have spent significant amount of resources...
Detecting RAT (Remote Access Trojan or Remote Administration Tool) used in APT (Advanced Persistent Threat) attacks is a challenging task. Many previous methods to detect RATs on the network require monitoring all network traffic. However, it is difficult to keep all network traffic because the size is too huge. Actually, we would have to detect RAT activity through insufficient information such as...
Greenhouse gas emission and climatic changes constitute major problems at an international level. That is why it is great importance to increase energy efficiency on large scale. New advanced power analysis platforms and new control algorithms are developed, in order to administrate the electricity consumption. I intended to give a clear image and a better understanding of the airport's power consumption...
This paper presents a smart system based on Low Power Wide Area networks for a remote monitoring of technological room in unstaffed railway stations. The paper aim is the design of an efficient network scheme characterized by improved performance compared with the standard solution. Adopting an innovative smart System Control Strategy and a custom network topology, good results are reached in terms...
Following the Service-Oriented Architecture, a large number of diversified Cloud services are exposed as Web APIs (Application Program Interface), which serve as the contracts between the service providers and service consumers. Due to their massive and broad applications, any flaw in the cloud APIs may lead to serious consequences. API testing is thus necessary to ensure the availability, reliability,...
The advances in virtual engineering brought about the creation of models of physical systems. This has been enhanced by the use of relevant standards and web technologies to develop interfaces for monitoring and controlling industrial systems at the shop floor or remotely over the internet. However, owing to the open nature of the internet as well as vulnerabilities associated with internet-based...
Large amounts of RFI(Radio Frequency Interference) are observed in the data obtained over East Asia, North America and Europe by L-band missions of SMOS, Aquarius and SMAP etc. Multiple approaches have been proposed to detect and eliminate the RFI signals in the past few decades. This paper focuses on a new potential RFI detection and mitigation method that is based on the Local Outlier Factor (LOF)...
Land cover is an important earth observation parameter for understanding the Earth's ecosystem. Compared with optical sensors, Synthetic Aperture Radar (SAR) enables more rapid land cover monitoring with its all-weather, day-and-night imaging capability. We mosaicked 390 scenes of PALSAR-2 fully polarimetric data acquired in Japan and computed several polarimetric decompositions. Then, we applied...
A cost-efficient framework for executing life-time dependability procedures is presented in this paper. The proposed framework relies on distributed sensors and actuators (embedded instruments) for self-awareness and adaptation, where the IEEE 1687 standard (iJTAG) is utilized for the dependability communications and the on-chip access of the instruments.
