In view of the shortcomings of traditional fault diagnosis system in accuracy, robustness and too complicated recognition algorithm, the distributed intelligent fault diagnosis system is presentation based on ZigBee technology and particle filter. Multi variable data's acquisition and centralized treatment is realized through the wireless sensor network, and the accurate estimation of the state of...
Smart farming is seen to be the future of agriculture as it produces higher quality of crops by making farms more intelligent in sensing its controlling parameters. Analyzing massive amount of data can be done by accessing and connecting various devices with the help of Internet of Things (IoT). However, it is not enough to have an Internet support and self-updating readings from the sensors but also...
In Japan, about 50 thousand heat stroke patients are emergency transported and die more than 0.1% (about 50–100) patients every year[1]. This study describes the development of the system that gives warning with consideration of high temperature and humidity so that operators at construction sites do not get heatstroke. This system does not only measure the temperature and the humidity near an office...
The paper deals with the on-line monitoring system integrated by the Italian TSO (Terna S.p.A.) in the HV substations. Arose from the long experience achieved, the latest integrated system is the SMOAT (acronym for Monitoring System for HV, in Italian). Infrastructure introduced by the online monitoring system, integrated into the Terna's existing expert systems (PSE, MBI) are also presented as well...
Thermal management is one of the key issues arising in designing light-emitting diode (LED) based luminaire products. Dynamic compact thermal models (DCTMs) are required to predict the thermal behaviour of LED packages fast and accurately in system level simulations. The European Delphi4LED consortium aims to develop multi-domain (electrical-thermal-optical) compact models. One of its targets is to...
Condition monitoring (CM) of gearbox is a crucial activity due to its importance in power transmission for many industrial applications. Monitoring temperature is an effective mean to collect useful information about the healthy conditions of the gearbox. This study investigates the use of a novel wireless temperature node to monitor and diagnose different faults on a gearbox transmission system under...
Museum environmental monitoring is an important issue for the artifact conservation. Many solutions have been proposed to tackle this problem, but the museum constraints prevent an easy application in several cases, especially if the monitoring has to be performed in museums where an environmental control system has been already installed. This paper describes a simple though powerful solution, which...
Water management and irrigation scheduling have become the main subjects of different studies in the last decades, due to their high influence on crop performance indicators. This study presents the most important parameters that have to be monitored in an irrigation management system and the most important ones are synthesized: air moisture and temperature, soil air and moisture, evapotranspiration...
The article considers the issue of the possibility of applying the phase-measuring method in inclinometric systems of geotechnical monitoring. The main problems with use of the inclinometric systems of geotechnical monitoring. The causes, causing the occurrence of angular measurement errors. The factors affecting the accuracy of inclinometric control. A new approach of construction for inclinometric...
The paper presents experimental research related to pH measuring and to the design of a system of pH monitoring. The paper is structured on three parts. The first part presents the principle of measuring the pH of a solution matter, the transducer structure and of the adaptor used. The second part is dedicated to the experimental research effectuated aiming at the use of PACTware software environment...
The questions of practical application of georadar sounding for the detailed studying of development of a karst were considered in the article. The importance of the problem being solved for the planning of construction and further operation of industrial facilities in karst limestone areas is emphasized. In the last case, the geodynamic control of karst zones is necessary, as operation of objects...
This paper presents a method of on-site density measurement of pressure transmitting medium at high pressures. The density is estimated by precisely detecting head differential pressure using a monitoring pressure gauge. A flexible pressure tube which is durable for high pressures is used to change the vertical position of the monitoring pressure gauge. We measured the density of dioctyl sebacate,...
Off-line ultrasonic non-destructive testing (NDT) is used to inspect defects in thermal power plants. However, for new-generation thermal power plants, off-line NDT is not sufficient and long-term monitoring at high temperature is desired. In the previous study, ultrasonic transducers made by CaBi4Ti4O15 (CBT)/Pb(Zr, Ti)O3 (PZT) were investigated and maximum operation temperature was estimated as...
Ultrasound offers measurements of parameters encountered in harsh environments such as steam generators, heat exchangers and nuclear reactor primary and secondary systems. But there is a lack of piezo-materials tolerant of high temperatures and nuclear irradiation. Another issue is that transducers are needed that can be left in place on curved surfaces such as pipes and valves. The transducers should...
High intensity focused ultrasound (HIFU) is a non-invasive thermal ablation technique. To perform the ablation procedure safely, temperature monitoring is employed to preserve healthy tissues while simultaneously ensuring that the targeted region is completely ablated. Ultrasound (US) thermometry techniques have the advantages of cost-effectiveness and portability over other medical imaging modalities...
A tracing method is proposed in this paper to identify lines for outage for ice accumulation prevention on overhead lines during storms. The objective is to increase current flow on at-risk line by sequential outages of other lines in the network. The higher current flow causes more resistive power loss on line which increases temperature on the surface of the conductor. The outages are applied to...
This paper addresses the development of electro-thermal models able to accurately predict the thermal behaviour of power modules in AC drives. The model would be implemented in the digital signal processor used to control the drive, operating therefore on line. FEM will be used for the design and calibration of the models. The performance of the proposed methods will be validated experimentally.
In safety-critical systems, many-processor Systems-on-Chip are being increasingly employed. An example is an imminent collision detection System-on-Chip for cars. Such a system requires zero downtime and a very high reliability despite aging issues under harsh environmental conditions. By monitoring the health status of processor cores and other IPs, and taking appropriate counteractions if required,...
Thermal strain imaging (TSI) is promising for lesion targeting and dose control in thermal-based treatment. We previously developed HIFU and temperature sensitive cerasomes (HTSCs) for local chemotherapy of cancer (Liang et al, Acs Nano 2015). However, the temperature within tissues cannot be noninvasively measured in vivo. The aim of this study was to investigate the feasibility of TSI in noninvasive...
High intensity focused ultrasound (HIFU) is a non-invasive thermal ablation technique. Ablating malignant tissue entirely while preserving as much healthy tissue as possible is challenging, requiring real-time monitoring for optimal results. Magnetic Resonance Imaging (MRI) is the current gold standard for HIFU monitoring, providing reliable temperature information in real-time. However, MRI has several...
