The use of nuclear energy to generate electric power is crucial in meeting the high energy demand of modern economy. The dependability of nuclear power plants has been a critical issue and the reactor containment is the most important safety structure acting as a barrier against the release of radioactive material to the environment. In this paper, we propose a practical framework for design, implementation,...
A cost effective and user-friendly indoor air quality (IAQ) monitoring system based on ZigBee wireless sensor network implemented with the TI CC2430 ZigBee chip is described. In this proposed system, a temperature and relative humidity sensing module and a carbon dioxide sensing module were integrated in each ensor node which was placed in different indoor environment to monitor the IAQ parameters...
This paper presents the automatic control of a temperature chamber. The temperature chambers are used to simulate temperatures from freezing temperatures to very high temperatures. These temperature chambers are often used for testing circuit board in the automotive industry, because this industry requires a big temperature interval. It will be presented three applications which can control temperature...
Affective or Emotion oriented computing constitutes an emerging research field that is still in its early stages. The lack of empirical results together with the complexity that attributes emotions, subjects research to a diversity of theories, models and tools. In the current paper we present a critical review of the state of the art on emotion measurement models, methods and tools and we suggest...
This media art installation aims to digitally reconstruct a traditional Chinese Guqin string instrument using physical sensing techniques, to invite bodily interpretation of the classical instrument. Guqin has a unique place in the Chinese history, as a symbol of the high culture of the nobles and intellectuals (Junzi, Superior Man). It's also seen as the vessel for pursuing harmony. Guqin is sometimes...
Wireless sensor networks (WSNs) have gained an increasing interest in logistic applications. In this paper, we propose a universal hardware and software architecture to measure environmental variables in a dynamic heterogeneous plug-and-play WSN. In this framework the physical structure of the WSN is automatically and transparently generated from the final user. Each node of the WSN communicates through...
It has great significance that monitoring temperature and pressure of reactor in chemical experiments and industrial production. In this paper, computer and intelligence instrument are connected by field bus into a small distributed control system, than, develop the on-line monitoring software for reactor based on LabVIEW platform, It has data collection, display, storage and analysis functions, and...
Owing to its small size, light weight, strong function and easily distributed control etc., single-chip microcomputer has been of wide application. However, there are lots of problems in experiment teaching on single-chip microcomputer technology. So, the single-chip microcomputer experiment teaching system for application is development, which can not only meet the experiment teaching in normal,...
Important improvements (ease of use and test, temperature correction, reliability‥) brought to the OSL sensor are introduced. The new architecture is detailed. Tests and a sectorial analysis are conducted.
The analog input signals of intelligent temperature transmitter (ITT) are milli-voltage signals, AD7714 was selected was selected for small signal acquisition. The new technology of potential lifting was explored to ensure the stability and accuracy of sampling. The wiring technology of small signal was presented. ITT's switching power supply was designed to meet the requirements of security and isolation...
This topic is raised in the current that the vehicle exhaust pollution has been increasing higher and higher standards of automobile exhaust testing, with the aim of eliminating environmental interference and improves the accuracy of the exhaust gas. The system overcomes the shortcomings of the existing automobile exhaust gas analyzer, using the compensation method to judge the exhaust gas. the system...
Clouds and the Earth's Radiant Energy System (CERES) Flight Model 5 (FM5) instrument is designed to continue the long-term monitoring of the Earth's radiation budget. CERES has three sensor units that measure radiation in the 0.3 – 5.0 µm, 0.3 – >100 µm and 8 – 12 µm wavelength regions. Prelaunch characterization of the sensors to determine their radiometric gain and spectral response function...
Calibration and validation of sensors is important for understanding how a sensor operates during its mission and shows the level of measurements that can be expected. The calibration is an on-going process throughout the mission but is most critical when the complete system comes together and during its initial stage after reaching orbit. Careful planning is required to accurately and efficiently...
The ATLAS silicon tracker community foresees an upgrade from the present octafluoropropane (C3F8) evaporative cooling fluid — to a composite fluid with a probable 10–20% admixture of hexafluoroethane (C2F6). Such a fluid will allow a lower evaporation temperature and will afford the tracker silicon substrates a better safety margin against leakage current-induced thermal runaway caused by cumulative...
The temperature protection is the important link for the protection of conveyance system in underground collieries. The infrared temperature sensor is used widely in domestic collieries, its stability, timeliness and precision etc. still need to be improve. The infrared imaging technology was used to analyze the infrared of the conveyance system, so as to realize the temperature monitor. It proved...
Because of the NATO Undersea Research Centre's long history of oceanographic instrument calibration, the growing application of underwater gliders in the oceanographic community and the difficulties in sensor characterization, the Centre is developing a complete set of facilities and procedures that allow within glider sensors calibration, validation and monitoring. Gliders typically carry a variety...
Adjusting of liquid crystal display (LCD) white balance is a key factor during the LCD production process. At present, LCD white balance is adjusted by PC on product line. This paper proposes a new method that automatic adjusting of LCD white balance will be implemented. Firstly, error of input signal and A/D is corrected based on embedded system of LCD. Secondly, difference of color temperature between...
The accuracy of the temperature measurement calibration in industry which consume a long process creates a chance that errors in the measurement influence the decision. The need of uncertainty analysis via virtual instrument is to provide a better measurement of that influence and likelihood of presented a wrong decision. Using the temperature calibration instrument, the purpose of this paper is to...
With the aim to improve the knowledge of nuclear fuel behaviour, the development of advanced instrumentation used during in-pile experiments in Material Testing Reactor (MTR) is necessary. To obtain data on high Burn-Up MOX fuel performance under transient operating conditions, especially in order to differentiate between the kinetics of fission gas and helium releases and to acquire data on the degradation...
Under the framework of French R&D studies for Generation IV reactors and more specifically for sodium-cooled fast reactors (SFR); the CEA, EDF and AREVA have launched a joint coordinated research programme. This paper deals with the R&D sets out to achieve better inspection, maintenance, availability and decommissioning. In particular the instrumentation requirements for core monitoring and...
