    2009-01-01

    As a result of the tremendous development of GSM services over the last years, the number of related services used by organizations has drastically increased. Therefore, monitoring GSM services is becoming a business critical issue in order to be able to react appropriately in case of incident. In order to provide with GSM coverage all the CERN underground facilities, more than 50 km of leaky feeder cable have been deployed. This infrastructure is also used to propagate VHF radio signals for the CERN’s fire brigade. Even though CERN’s mobile operator monitors the network, it cannot guarantee the availability of GSM services, and for sure not VHF services, where signals are carried by the leaky feeder cable. So, a global monitoring system has become critical to CERN. In addition, monitoring this infrastructure will allow to characterize its behaviour over time, especially with LHC operation. Given that commercial solutions were not yet mature, CERN developed a system based on GSM probes and an application...

To develop a timely response capability, the Radiation Safety Systems Division has launched a project to develop an advanced online measurement system for use in different threat scenarios, such as the release of radioactive materials to the environment during any nuclear or radiological accident. In order to meet this requirement a Global system for Mobile (GSM) based Radiation Monitoring system is designed and tested on field. It uses an energy compensated GM detector and is attached with commercially available Global Positioning System (GPS) for online acquisition of positional coordinates with time, and GSM modem for online data transfer. The equipment can be operated continuously while the vehicle is moving. The system is designed to provide measurement information, either raw data or analysis results, to the local database or to a remote database through a communication link. The system consumes ∼ 250 mA including the GPS and GSM enabling ∼ 30 hours of continuous radioactivity monitoring with a 12 Ah battery source. The system has been used in road based environmental radiation surveys carried out at various part of the country. With PC support, the system can map the radiological status online onto the map of the area being surveyed, to help decision-making on countermeasures during the survey and sending the online data at a remote station to enable the emergency managers to take appropriate decision.

    Full Text Available A Street light, lamppost, street lamp, light standard, or lamp standard is a raised source of light on the edge of a road or walkway, which is turned on or lit at a certain time every night. Major advantages of street lighting includes: prevention of accidents and increase in safety. Studies have shown that darkness results in a large number of crashes and fatalities, especially those involving pedestrians; pedestrian fatalities are 3 to 6.75 times more likely in the dark than in daylight. Street lighting has been found to reduce pedestrian crashes by approximately 50%.A number of street light control systems have been developed to control and reduce energy consumption of a town's public lighting system. These range from controlling a circuit of street lights and/or individual lights with specific ballasts and network operating protocols. These may include sending and receiving instructions via separate data networks, athigh frequency over the top of the low voltage supply or wireless. Various protocols have been developed as well as compatible hardware for most types of lighting. The control center will deal with thedata so that it can know the situation of each streetlight. According to the result the control center gives orders to each streetlight to control the switch state and illumination of them [1]-[2].

    2005-07-01

    Global Positioning Systems (GPS) are considered suitable to monitor the position and velocity of horses during cross-country competition or in training. Furthermore, simultaneous recording of life data such as heart rate could be useful to assess the horse's condition during exercise. To test the suitability and reliability of a commercially available GPS system with integrated heart rate recording system and with built in GSM for data transmission, the Fidelak Equipilot Type EP-2003-15/G-2.11 (EP-15/G) was evaluated first for reliability of pulse recording from a pulse generator within the physiological range of horses; furthermore distance, velocity and heart rate recordings were carried out on a standard 1000 m field track with five repetitions. Agreement (% deviation from actually measured distance and from stopwatch-distance based velocity calculations) and variability (Coefficient of Variation for distance, velocity, heart rate) were calculated. From the results it was safe to assume that the heart rate sensor recorded horse heart rates at a high degree of accuracy. Overall distances and velocities are in high agreement with actually measured values. However, overall variability expressed in terms of relative variability (C.V.) is smaller for distance recording (C.V. 0.68%) when compared to velocity (C.V. 1.01%). The system tested is suitable and reliable for simultaneously recording of distance, velocity and heart rates for horses during cross country exercise. GPS-based monitoring of movement along with simultaneous recording of physiological data and the possibility to call upon data will not only be of benefit for training horses or for surveillance during competition, it may also be suitable for distant patient monitoring and in behavioural studies as well as in veterinary medicine in general.

  19. Solar powered environmental radiation monitor with GSM based data communication

    This paper describes the development and features of a solar powered system for monitoring of environmental radiation for detection of nuclear emergency. It is essential that a system which is meant for detection of nuclear emergency must be installed in open environment so that the changes in environmental radiation level can be readily and accurately monitored. The traditional systems employ mains power which is subject to various problems like load shedding, power fluctuations, power transients and brown outs. Being powered by solar cells with battery backup, the system is free from the vagaries of mains power. The system employs GSM Modem for data communication to the central station. GSM cellular network provides more reliable data communication as compared to the dialup land line network. The system is adopted by the Indian Environmental Radiation Monitoring Network (IERMON) for deployment across India. Being developed and manufactured indigenously at low cost, a large scale monitoring network across the country is readily achievable. Under IERMON about 100 systems were manufactured and being deployed. This paper describes the design of the solar powered environmental radiation monitor deployed in IERMON network. With the help of a block diagram the various constituents of the system are explained. The features of the system are highlighted. The calibration and the performance of the system are explained in the subsequent part of the paper. (author)

    Full Text Available Voting is the foundation of a democratic system of government, whether the system uses direct or representative governance. To increase the efficiency and accuracy of voting procedures, computerized voting systems were developed to help collecting and counting the votes. For a variety of reasons, voters may be unable to attend voting booths physically, but need to vote remotely, for example, from home or while traveling abroad. Hence, there is great demand for remote voting procedures that are easy, transparent, and, most importantly, secure. Numerous electronic voting schemes have been proposed in the past, but most of them have failed to provide voter authentication in an efficient and transparent way. On the other hand, GSM (Global System for Mobile communications is the most widely used mobile networking standard. In this paper, an polling scheme using GSM mobile technology is presented.

    LAXMI

    2013-05-01

    Full Text Available In this technical world where technology is growing up day by day and scientific researches are presenting a new era of discoveries, we need security in all the areas. As theft activities are increasing around, we have need of more security in Automobiles/Vehicles. Today automobile industry is a major industry of the world and the vehicles need to be secured otherwise they will be packed gifts for the criminals given by our own hands. The main aim of this paper is to use wireless technology to intimate the owner of the vehicle about each and every unauthorized attempt of entry to his/her vehicle. The auto-generated Short Message Service by system is used to give information to the owner’s cell phone. And one more advantage of this project is that a back Short Message Service can be send by vehicle’s owner which will disable the ignition of the vehicle system and vehicle will be stopped. If system is active and if any unauthorized person tries to start the vehicle, the microcontroller used insystem gets an interrupt through a switch which is connected to the security system. Instantly microcontroller commands the Global System for Mobile modem to send an auto-generated message. The owner receives the Short Message Service alert in the form of some written text which is predefined in the system. If he is not sure about the jumper, owner can send a back message to the Global System for Mobile modem to ‘stop’. The Global System for Mobile modem which is interfaced to the microcontroller receives the message, according to the output of Global System for Mobile modem, micro controller disables the ignition, and it will result in stopping of the vehicle. Advancement to this system is that we can transmit auto-generated Multimedia Message Service instead of Short Message Service by using smart phone.

As we know, this is not resistant to fake BTS attack. But for the huge cost for building a fake BTS before, this kind of attack were not really implemented before. This paper presents an implement of fake BTS based on software radio technologies. Furthermore, this paper discusses two types of fake BTS attacks on our software radio platform. The first attack is IMSI/IMEI catch attack, which can get the mobile phone’s IMSI and IMEI. With this information, attacker can got the track of the man with this phone. The second attack is selective jamming attack. After get the IMSI and IMEI of the mobile phone, the attackers can decide whether the mobile phone is blocked or not. We will analyze the GSM protocol which is relevant to the interception system and later present the performance of such a system by real tests and demonstrate its feasibility.

  1. WATER-LEVEL MONITOR FOR BOREWELL AND WATER TANK BASED ON GSM

    R.Ramani

    2012-10-01

    Full Text Available Now a days, home automation & remote control and monitoring systems have seen a rapid growth in terms of technology. Apparently there is no early warning system to monitor the tank water level and bore well water level when it has reached the critical level. In this paper we have provided water level monitoring in the tank as well as in the bore well. If the water level in a bore well drops below the threshold level for pumping its pump motor may get air locked or more burn out due to dry running. It is awkward for farmers to walk all the way to their fields at night just to switch the pump motor off. Besides, he may never get to identify the problem. This problem can be solved by using this GSM based system that will automatically make a call to the user mobile phone, when the water Level in the bore well drops threshold below or rises to the threshold level for pumping. The user can also remotely switch on or off the pump motor by sending a SMS from his mobile phone. The system is simple, reliable, portable and affordable. We proposed the work in which, Whenever water level in the tankdrops below the required level the system try to fill the tank by switching on the bore well motor to pump the water into the tank It is must to have enough water in the bore well to avoid the formation of air gap or empty running of bore well motor. High precision water level sensor is used to identify the reference water level to activate and deactivate the motor and system properly by interfacing the sensor devices into the well definedembedded system.

  3. Interworking and integration of the Inmarsat Standard-M with Pan-European GSM system

    Tafazolli, R.; Evans, B. G.

    1993-01-01

    The market demand on mobile telephone communications has been increasing since the introduction of the cellular mobile telephone systems about twelve years ago. In Europe, projections indicate a demand of about 17 million subscribers for a fully deployed Pan European system. The Pan-European GSM system is to harmonize the growth of the terrestrial mobile system. Studies conducted by the European Space Agency (ESA) indicate that even with 60-70 percent of the area being covered by the GSM, a significant traffic demand (voice and data) will still exist for areas not covered by the terrestrial systems. This demand could be satisfied by a land mobile satellite system. The satellite system is therefore seen in a complementary role rather than in competition with the terrestrial system in an integrated telecommunications network. One possible scenario may be that initially the satellite system provides services to the rural areas together with areas still not covered by the GSM system. This service area is then gradually diminished as the terrestrial system expands until an optimum point is reached where the systems co-exist optimally. The objective of this paper is to investigate the possibility of integration of a space based system, in this case Inmarsat Standard-M, with the GSM (Global System for Mobile communications). One very important advantage of incorporating GSM services in Standard-M is that it will be feasible to extend the GSM services economically worldwide, not only to land mobiles but also to aeronautical and maritime mobiles.

    This project is about producing a prototype to feed fishes at fish ponds of remote location with the use of GSM mobile phone. An automatic fish feeder is an electric device that has been designed to give out the right amount of pellets at the designed time. In this project, the automatic feeder designed consists of photovoltaic solar cells that are used to generate electricity and storing it into batteries. Solar charge controllers can be used to determine the rate of which current is drawn and added from the batteries. GSM cellular communication is used to allow user to control from a distance. Commands or instructions are sent to the operating system which in return runs the servomotor and blower by blowing certain amount of fish pallets into the pond to feed the fishes. The duration of the feeding processes is fixed by the user, hence the amount of fish food pallets released are precisely the same for each time. This technology is especially useful for fish farmers where they can remotely feed their fishes.

    Full text: We present in this paper a new concept of gamma radiation portal detector, where the detection process is monitored by a micro-controller, coupled to a compatible GSM communication system, which is suitable to be accessed by all mobile phone operators worldwide. The signal generated at the detectors is converted by an A/D circuit, and driven to a micro-controller where a software evaluates the signal conditions and, depending on a previously set program, it triggers a communication system which sends the alarm to any computer linked to internet and/or to any mobile phone protocol by a specific software linked to the portal. The control electronic system is compatible to several detectors types, ranging from gas based devices to solid state ones. The portal is totally compatible with the ANSI - Standard N42.35 - 2004. It can be used in all types of government and industrial control scenarios. Its measure device permits the use of the equipment in all range of sensibility and in tracking radiation signals where it is. (author)

    2014-05-01

    Recent years have been characterized by an increase in the air traffic. More attention over micro-economic and macroeconomic indexes would be strategic to gather and enhance the safety of a flight and customer needing, for communicating by wireless handhelds on-board aircrafts. Thus, European Telecommunications Standards Institute (ETSI) proposed a GSM On Board (GSMOBA) system as a possible solution, allowing mobile terminals to communicate through GSM system on aircraft, avoiding electromagnetic interferences with radio components aboard. The main issues are directly related with interferences that could spring-out when mobile terminals attempt to connect to ground BTS, from the airplane. This kind of system is able to resolve the problem in terms of conformance of Effective Isotropic Radiated Power (EIRP) limits, defined outside the aircraft, by using an On board BTS (OBTS) and modeling the relevant key RF parameters on the air. The main purpose of this work is to illustrate the state-of-the-art of literature and previous studies about the problem, giving also a good detail of technical and normative references.

    2014-12-01

    Full Text Available The largest cause of unnatural deaths in the world today (apart from diseases is road accidents. With increase in population and thus in the number of vehicles, accidents are only going to increase. Most of these deaths are due to delay in medical attention to the injured. The major cause of this delay is lack of intimation or delayed intimation of the accident to emergency medical response authorities. This can be addressed by the system proposed. This system uses an accelerometer, GSM modem and a GPS device along with a microcontroller to report an accident. The system also incorporates a “panic switch” which when depressed will send a text message for help to stored numbers. This facility provides assistance in the case of some chronic medical condition like heart attack or robberies that are increasing on highways.

    Lightning is one type of transient faults that usually cause the circuit breaker in the distribution board trip due to overload current detection. The instant tripping condition in the circuit breakers clears the fault in the system. Unfortunately most circuit breakers system is manually operated. The power line will be effectively re-energized after the clearing fault process is finished. Auto-reclose circuit is used on the transmission line to carry out the duty of supplying quality electrical power to customers. In this project, an automatic reclose circuit breaker for low voltage usage is designed. The product description is the Auto Reclose Circuit Breaker (ARCB) will trip if the current sensor detects high current which exceeds the rated current for the miniature circuit breaker (MCB) used. Then the fault condition will be cleared automatically and return the power line to normal condition. The Global System for Mobile Communication (GSM) system will send SMS to the person in charge if the tripping occurs. If the over current occurs in three times, the system will fully trip (open circuit) and at the same time will send an SMS to the person in charge. In this project a 1 A is set as the rated current and any current exceeding a 1 A will cause the system to trip or interrupted. This system also provides an additional notification for user such as the emergency light and warning system.

    Current security model in Global System for Mobile Communications (GSM) predominantly use symmetric key cryptography. The rapid advancement of Internet technology facilitates online trading, banking, downloading, emailing using resource-constrained handheld devices such as personal digital assistants and cell phones. However, these applications require more security than the present GSM supports. Consequently, a careful design of GSM security using both symmetric and asymmetric key cryptography would make GSM security more adaptable in security intensive applications. This paper presents a secure and efficient protocol for GSM security using identity based cryptography. The salient features of the proposed protocol are (i) authenticated key exchange; (ii) mutual authentication amongst communicating entities; and (iii) user anonymity. The security analysis of the protocol shows its strength against some known threats observed in conventional GSM security.

  1. Wearable vital parameters monitoring system

    Caramaliu, Radu Vadim; Vasile, Alexandru; Bacis, Irina

    2015-02-01

    The system we propose monitors body temperature, heart rate and beside this, it tracks if the person who wears it suffers a faint. It uses a digital temperature sensor, a pulse sensor and a gravitational acceleration sensor to monitor the eventual faint or small heights free falls. The system continuously tracks the GPS position when available and stores the last valid data. So, when measuring abnormal vital parameters the module will send an SMS, using the GSM cellular network , with the person's social security number, the last valid GPS position for that person, the heart rate, the body temperature and, where applicable, a valid fall alert or non-valid fall alert. Even though such systems exist, they contain only faint detection or heart rate detection. Usually there is a strong correlation between low/high heart rate and an eventual faint. Combining both features into one system results in a more reliable detection device.

  9. 准平坦地形GSM-R电波传播特性研究%Research of the Electromagnetic Wave Propagation in GSM-R System with Quasi-flat Terrain

    崔勇; 张啸天

    2012-01-01

    城市的电波传播以衍射机制为主,其大尺度衰落特性的预测通常采用基于统计模型的Okumura模型和Hata模型.这两种模型未考虑小尺度衰落.同时,如果对准平坦环境下高速铁路GSM-R信号的大尺度衰落预测,还需要进行适当的修正.本文首先对准平坦地形下铁路沿线GSM-R电波传播进行理论分析,认为其传播方式以一条直射路径和若干条反射路径为主.然后建立起4路径仿真模型.通过该模型计算得出小区各个位置场强分布,同时得到大、小尺度衰落特性.最后对仿真结果和实测结果进行统计分析,统计结果显示了模型的有效性.%Diffraction is the main way by which electromagnetic waves propagate in urban areas. Its large-scale fading may be estimated by the Okumura and Hata models. However, small-scale fading has not been taken into consideration in the above two models. The above two models need to be modified to estimate the large-scale fading of the GSM-R system in the quasi-flat terrain. It can be understood that the electromagnetic waves in the quasi-flat terrain usually propagate to the receiver by the line of sight (LOS) or by a few reflection ways. Based on the above analysis, the 4-way simulation model was established. Both the large-scale and small-scale fading properties can be obtained from the model. The statistics of the simulation results are close to the measured results, showing the validity of the simulation model.

  10. Exposure setup to study potential adverse effects at GSM 1800 and UMTS frequencies on the auditory systems of rats

    To investigate possible biological effects of exposure to electromagnetic (EM) fields at the frequencies of global system for mobile communication (GSM) 1800 system and universal mobile telecommunication system (UMTS) on the auditory system of rats, an exposure setup for in vivo experiments is presented. The study was carried out in the framework of two European research projects. The target of the investigation was the cochlea. A dosimetric study was performed, both numerically and through direct measurements, to assess the interaction of the radiated fields and the dose distribution in the biological target. For the local exposure of rats, a loop antenna operating at the frequency bands of interest was designed, realised and characterised through numerical and experimental dosimetric procedures. Moreover, an exposure apparatus was set up, consisting of three arrays of four loop antennas, placed on three levels, thus allowing simultaneous exposure of 12 rats to give statistical power to the experiments. To isolate the exposure arrays, the setup was assembled by a wooden rack with EM field absorbing panels, inserted among the levels and at the four sides of the rack. Isolation was verified by direct measurements. Two exposure arrays were simultaneously supplied, whereas the third one was used for sham exposure. Blind exposure was achieved through a black box, hiding physical connections to the microwave power supply. During exposure sessions, rats were restrained in special plastic jigs for repeatable positioning, thus assuring the fixed level of dose in the target. (authors)

  18. Reduction of Bumblebee Noise Generated by GSM

    Han Su Kyi

    2014-09-01

    Full Text Available This research work presents a method for reducing a bumblebee noise generated by a GSM system. Global smart phone penetration has been very swift and 2nd generation, 3rd generation and 4th generation communication technology are commercially used in the world. GSM technology uses a channel access method that combines frequency division multiple access (FDMA and time division multiple access (TDMA. There are four commercial frequency bands. GSM technology has a burst structure by a TDMA method. And hence, the GSM technology has a disadvantage; radiation noise is generated from an antenna propagation signal of the smart phone, and consequently, the voice quality of the smart phone is degraded. This noise is commonly known as bumblebee noise, buzz noise or TDMA noise. There have been several studies to reduce the noise since a release of GSM technology in a commercial market. Those studies mainly focused on designing infinite impulse response (IIR notch filters by the signal processing technology or on data burst transmission schemes.

    The paper is focused on the building ad-hoc GSM network based on open source software and low-cost hardware. The created Base Transmission Station can be deployed and put into operation in a few minutes in a required area to ensure private communication between connected GSM mobile terminals. The convergence between BTS station and the other networks is possible through IP network. The paper tries to define connection parameters to provide sufficient quality of voice service between the GSM network and IP Multimedia Subsystem. The paper brings practical results of voice call quality measurement between users inside BTS station mobile network and users inside IP Multimedia Subsystem network. The calls are simulated by low-cost embedded solution for speech quality measurement in GSM network. This tool is under development of our laboratory and allows automatic speech quality measurement of any GSM or UMTS mobile network. The Perceptual Evaluation of Speech Quality method is used to get final comparable results. The communication between BTS station and connected networks has to be secured against the interception from the third party. The influence of the securing method for quality of service is presented in detail. Paper, apart from the quality of service measurement section, describes technical requirements for successful interconnection between BTS and IMS networks. The authentication, authorization and accounting methods in roaming between BTS and IMS system are presented too.

    2011-01-01

    The use of behavioural contracts, to specify, regulate and verify systems, is particularly relevant to runtime monitoring of distributed systems. System distribution poses major challenges to contract monitoring, from monitoring-induced information leaks to computation load balancing, communication overheads and fault-tolerance. We present mDPi, a location-aware process calculus, for reasoning about monitoring of distributed systems. We define a family of Labelled Transition Systems for this calculus, which allow formal reasoning about different monitoring strategies at different levels of abstractions. We also illustrate the expressivity of the calculus by showing how contracts in a simple contract language can be synthesised into different mDPi monitors.

  10. Radioactive source monitoring system based on RFID and GPRS

    Nuclear radiation produced by radioactive source is harmful to the health of human body, and the lost and theft of radioactive source will cause environmental pollution and social panic. In order to solve the abnormal leaks, accidental loss, theft and other problems of the radioactive source, a radioactive source monitoring system based on RFID, GPS, GPRS and GSM technology is put forward. Radiation dose detector and GPS wireless location module are used to obtain the information of radiation dose and location respectively, RFID reader reads the status of a tag fixed on the bottom of the radioactive source. All information is transmitted to the remote monitoring center via GPRS wireless transmission. There will be an audible and visual alarm when radiation dose is out of limits or the state of radioactive source is abnormal, and the monitoring center will send alarming text messages to the managers through GSM Modem at the same time. Thus, the functions of monitoring and alarming are achieved. The system has already been put into operation and is being kept in functional order. It can provide stable statistics as well as accurate alarm, improving the supervision of radioactive source effectively. (authors)

  11. SMART ON-BOARD TRANSPORTATION MANAGEMENT SYSTEM USING GPS/GSM/GPRS TECHNOLOGIES TO REDUCE TRAFFIC VIOLATION IN DEVELOPING COUNTRIES

    Saed Tarapiah

    2014-03-01

    Full Text Available Nowadays, the evolution in transportation technologies makes the necessity for increasing road safety. In this context, we propose the implementation of a smart onboard GPS/GPRS system to be attached to vehicles for monitoring and controlling their speed. In case of traffic speed violation, a GPRS message containing information about the vehicle such as location and maximum speed is sent to a hosting server located in an authorized office so that the violated vehicle is ticketed. Moreover, this system can also track the vehicle’s current location on a Google Map, which is mostly beneficial when vehicles should follow a specific road and in case of robbery. Also geo-casting can have a major role in this model. Some sensors, such as shock/vibration sensor usually attached to the air-bags in vehicles, are attached to the system that in case of accident, it will send notifications to the nearest hospital, police station and civil defense. Our proposed model can be utilized for different implementations, both in public and private sectors. While similar existing systems in Palestine have focalized just on the tracking aspect of vehicles’ monitoring, it would be the first system supporting both ticketing and tracking.

    This project can be considered as a model for a simplified grid monitoring. In particular, I was creating a specific monitoring instance, which can be easily set up on a machine and, depending on an input information, automatically start monitoring services using Nagios software application. I had to automate the set up process and configuration of the monitoring system in order for the user to use it easily. I developed a script which automatically sets up the monitoring system, configures it and starts monitoring. I put the script, files and instructions in the repository 'https://git.cern.ch/web/?p=cosmic.git;a=summary' under the sub-directory called SNCG.

  14. Breaking GSM with rainbow Tables

    Meyer, Steven

    2011-01-01

    Since 1998 the GSM security has been academically broken but no real attack has ever been done until in 2008 when two engineers of Pico Computing (FPGA manufacture) revealed that they could break the GSM encryption in 30 seconds with 200'000$ hardware and precomputed rainbow tables. Since then the hardware was either available for rich people only or was confiscated by government agencies. So Chris Paget and Karsten Nohl decided to react and do the same thing but in a distributed open source form (on torrent). This way everybody could "enjoy" breaking GSM security and operators will be forced to upgrade the GSM protocol that is being used by more than 4 billion users and that is more than 20 years old.

    2011-09-01

    Full Text Available The use of behavioural contracts, to specify, regulate and verify systems, is particularly relevant to runtime monitoring of distributed systems. System distribution poses major challenges to contract monitoring, from monitoring-induced information leaks to computation load balancing, communication overheads and fault-tolerance. We present mDPi, a location-aware process calculus, for reasoning about monitoring of distributed systems. We define a family of Labelled Transition Systems for this calculus, which allow formal reasoning about different monitoring strategies at different levels of abstractions. We also illustrate the expressivity of the calculus by showing how contracts in a simple contract language can be synthesised into different mDPi monitors.

  1. Monitoring Cray Cooling Systems

    Maxwell, Don E [ORNL; Ezell, Matthew A [ORNL; Becklehimer, Jeff [Cray, Inc.; Donovan, Matthew J [ORNL; Layton, Christopher C [ORNL

    2014-01-01

    While sites generally have systems in place to monitor the health of Cray computers themselves, often the cooling systems are ignored until a computer failure requires investigation into the source of the failure. The Liebert XDP units used to cool the Cray XE/XK models as well as the Cray proprietary cooling system used for the Cray XC30 models provide data useful for health monitoring. Unfortunately, this valuable information is often available only to custom solutions not accessible by a center-wide monitoring system or is simply ignored entirely. In this paper, methods and tools used to harvest the monitoring data available are discussed, and the implementation needed to integrate the data into a center-wide monitoring system at the Oak Ridge National Laboratory is provided.

  2. Safety system status monitoring

    The Pacific Northwest Laboratory has studied the safety aspects of monitoring the preoperational status of safety systems in nuclear power plants. The goals of the study were to assess for the NRC the effectiveness of current monitoring systems and procedures, to develop near-term guidelines for reducing human errors associated with monitoring safety system status, and to recommend a regulatory position on this issue. A review of safety system status monitoring practices indicated that current systems and procedures do not adequately aid control room operators in monitoring safety system status. This is true even of some systems and procedures installed to meet existing regulatory guidelines (Regulatory Guide 1.47). In consequence, this report suggests acceptance criteria for meeting the functional requirements of an adequate system for monitoring safety system status. Also suggested are near-term guidelines that could reduce the likelihood of human errors in specific, high-priority status monitoring tasks. It is recommended that (1) Regulatory Guide 1.47 be revised to address these acceptance criteria, and (2) the revised Regulatory Guide 1.47 be applied to all plants, including those built since the issuance of the original Regulatory Guide

    2014-07-01

    Full Text Available Childbirth is generally time of joy for parents and families. As per the medical reports each year 4 million newborns die within 28 days of birth and more suffer from disability, disease, infection and injury. The enabling environment for safe childbirth depends on the care and attention required to newborns by health personnel and the availability of adequate health-care facilities, equipment, and medicines and emergency care when needed. Neonatal monitoring refers to the monitoring of vital physiological parameters of premature infants. Continuous health monitoring of the neonates provides crucial parameters for early detection of adverse events. Health monitoring for the neonates provides crucial parameters for urgent diagnoses and corresponding medical procedures, subsequently increasing the survival rates. In the present paper, we propose a proto type design of a neonatal monitoring system. The system is designed and integrated with different health measurement and display devices. The prototype design is very much useful for monitor the physiological parameters of infants.

  9. Remote monitoring system

    The present invention provides a system for remote diagnosis of facilities disposed to not accessible places and for confirming a state of the inside of closed chambers upon occurrence of abnormality. Namely, a flying type monitoring robot is used as a monitoring means. When monitoring the inside of a closed vessel in the plant, a mechanism for securing the flying type monitoring robot secured to the chamber can be released from outside of the chamber. Then, when abnormality should occur in the chamber, the condition can be confirmed from various view points by remote operation. In addition, if the securing mechanism is released by alarm signals of a different plant monitoring system, influences of abnormality occurred in a different plant applied to the closed chamber can be confirmed, and presence or absence of abnormality can be monitored by remote operation. In addition, when an automatic navigation system is loaded on the flying type monitoring robot, the securing mechanism can be released by alarm signals of the different plant monitoring system in addition to the robot can stand-by while hovering at a predetermined place and fly to a place to be assumed as abnormal under automatic control.

    Chomtong, P.; Akkaraekthalin, P.

    2014-05-01

    This paper presents a triple-band bandpass filter for applications of GSM, WiMAX, and WLAN systems. The proposed filter comprises of the tri-section step-impedance and capacitively loaded step-impedance resonators, which are combined using the cross coupling technique. Additionally, tapered lines are used to connect at both ports of the filter in order to enhance matching for the tri-band resonant frequencies. The filter can operate at the resonant frequencies of 1.8 GHz, 3.7 GHz, and 5.5 GHz. At resonant frequencies, the measured values of S11 are -17.2 dB, -33.6 dB, and -17.9 dB, while the measured values of S21 are -2.23 dB, -2.98 dB, and -3.31 dB, respectively. Moreover, the presented filter has compact size compared with the conventional open-loop cross coupling triple band bandpass filters

  12. Remote maintenance monitoring system

    Simpkins, Lorenz G. (Inventor); Owens, Richard C. (Inventor); Rochette, Donn A. (Inventor)

    1992-01-01

    A remote maintenance monitoring system retrofits to a given hardware device with a sensor implant which gathers and captures failure data from the hardware device, without interfering with its operation. Failure data is continuously obtained from predetermined critical points within the hardware device, and is analyzed with a diagnostic expert system, which isolates failure origin to a particular component within the hardware device. For example, monitoring of a computer-based device may include monitoring of parity error data therefrom, as well as monitoring power supply fluctuations therein, so that parity error and power supply anomaly data may be used to trace the failure origin to a particular plane or power supply within the computer-based device. A plurality of sensor implants may be rerofit to corresponding plural devices comprising a distributed large-scale system. Transparent interface of the sensors to the devices precludes operative interference with the distributed network. Retrofit capability of the sensors permits monitoring of even older devices having no built-in testing technology. Continuous real time monitoring of a distributed network of such devices, coupled with diagnostic expert system analysis thereof, permits capture and analysis of even intermittent failures, thereby facilitating maintenance of the monitored large-scale system.

  16. Comparison of GSM Modulated and CW Radiofrequency Radiation on Cells

    The aim of our study was to evaluate and compare effect of global system of mobile (GSM) modulation and continuous wave (CW) radiofrequency radiation (RF) on proliferation ability and viability of V79 Chinese hamster lung cells. Previously prepared samples of cells in culture were exposed for 1, 2 and 3 hours both to 915 MHz GSM modulated and to 935 MHz CW RF field in gigahertz transversal electromagnetic mode cell (GTEM-cell). Electric field strength for cells exposed to GSM modulation was set at 10 V/m and for CW exposed cells was 8.2 V/m. Average specific absorption rate (SAR) was calculated to be for GSM 0.23 W/kg and for CW 0.12 W/kg. V79 samples were plated in concentration of 1x104cells/mL. Cell proliferation was determined by cell counts for each hour of exposure during five post-exposure days. Trypan blue exclusion test was used to determine cell viability. In comparison to control cell samples, proliferation of GSM irradiated cells showed significant decrease after 3 hours of exposure on the second and third post-exposure day. CW exposed cell samples showed significant decrease after 3 hours of exposure on the third post-exposure day. Viability of GSM and CW exposed cells did not significantly differ from matched control cell samples. Both applied RF fields have shown similar effect on cell culture growth, and cell viability of V79 cell line. In addition, applied GSM modulated RF radiation demonstrate bigger influence on proliferation of cells. (author)

    2012-01-01

    Runtime verification (RV) is a natural fit for ultra-critical systems, where correctness is imperative. In ultra-critical systems, even if the software is fault-free, because of the inherent unreliability of commodity hardware and the adversity of operational environments, processing units (and their hosted software) are replicated, and fault-tolerant algorithms are used to compare the outputs. We investigate both software monitoring in distributed fault-tolerant systems, as well as implementing fault-tolerance mechanisms using RV techniques. We describe the Copilot language and compiler, specifically designed for generating monitors for distributed, hard real-time systems. We also describe two case-studies in which we generated Copilot monitors in avionics systems.

  18. Development of structural health monitoring and early warning system for reinforced concrete system

    Many buildings have been damaged due to earthquakes that occurred recently in Indonesia. The main cause of the damage is the large deformation of the building structural component cannot accommodate properly. Therefore, it is necessary to develop the Structural Health Monitoring System (SHMS) to measure precisely the deformation of the building structural component in the real time conditions. This paper presents the development of SHMS for reinforced concrete structural system. This monitoring system is based on deformation component such as strain of reinforcement bar, concrete strain, and displacement of reinforced concrete component. Since the deformation component has exceeded the limit value, the warning message can be sent to the building occupies. This warning message has also can be performed as early warning system of the reinforced concrete structural system. The warning message can also be sent via Short Message Service (SMS) through the Global System for Mobile Communications (GSM) network. Hence, the SHMS should be integrated with internet modem to connect with GSM network. Additionally, the SHMS program is verified with experimental study of simply supported reinforced concrete beam. Verification results show that the SHMS has good agreement with experimental results

  20. New head exposure system for use in human provocation studies with EEG recording during GSM900- and UMTS-like exposure.

    Schmid, Gernot; Cecil, Stefan; Goger, Christoph; Trimmel, Michael; Kuster, Niels; Molla-Djafari, Hamid

    2007-12-01

    A new head exposure system for double blinded human provocation studies, which requires EEG recording during exposure with GSM900- and UMTS-like signals has been developed and dosimetrically evaluated. The system uses planar patch antennas fixed at 65 mm distance from the subject's head by a special headset, which provides minimum impairment of the test subjects and ensures an almost constant position of the antennas with respect to the head, even in case of head movements. Compared to exposure concepts operating small antennas in close proximity to the head, the concept of planar antennas at a certain distance from the head produces a much more homogeneous SAR distribution in the temporal and parietal lobe of the brain. At the same time the resulting uncertainty of exposure due to variations in head size, variations of the dielectric properties of tissues and unavoidable small changes of the antenna's position with respect to the head, is reduced to the order of approximately 3 dB, which is a significant improvement to comparable head exposure systems reported in literature in the past. To avoid electromagnetic interference on the EEG recording caused by the incident RF-field an appropriate double-shielded filter circuit has been developed. Furthermore, the effect of the presence of the sintered Ag/AgCl EEG electrodes and electrode wires on the SAR distribution inside the head has been investigated and was found to be minimal if the electrode wires are arranged orthogonal to the incident electric field vector. EEG electrode arrangement parallel to the incident field vector, however, might cause drastic changes in the SAR distribution inside the head. PMID:17654486

    The Urine Monitoring System (UMS) is a system designed to collect an individual crewmember's void, gently separate urine from air, accurately measure void volume, allow for void sample acquisition, and discharge remaining urine into the Waste Collector Subsystem (WCS) onboard the International Space Station. The Urine Monitoring System (UMS) is a successor design to the existing Space Shuttle system and will resolve anomalies such as: liquid carry-over, inaccurate void volume measurements, and cross contamination in void samples. The crew will perform an evaluation of airflow at the ISS UMS urinal hose interface, a calibration evaluation, and a full user interface evaluation. o The UMS can be used to facilitate non-invasive methods for monitoring crew health, evaluation of countermeasures, and implementation of a variety of biomedical research protocols on future exploration missions.

  2. A low-cost GPS GSM/GPRS telemetry system: performance in stationary field tests and preliminary data on wild otters (Lutra lutra.

    Lorenzo Quaglietta

    Full Text Available BACKGROUND: Despite the increasing worldwide use of global positioning system (GPS telemetry in wildlife research, it has never been tested on any freshwater diving animal or in the peculiar conditions of the riparian habitat, despite this latter being one of the most important habitat types for many animal taxa. Moreover, in most cases, the GPS devices used have been commercial and expensive, limiting their use in low-budget projects. METHODOLOGY/PRINCIPAL FINDINGS: We have developed a low-cost, easily constructed GPS GSM/GPRS (Global System for Mobile Communications/General Packet Radio Service and examined its performance in stationary tests, by assessing the influence of different habitat types, including the riparian, as well as water submersion and certain climatic and environmental variables on GPS fix-success rate and accuracy. We then tested the GPS on wild diving animals, applying it, for the first time, to an otter species (Lutra lutra. The rate of locations acquired during the stationary tests reached 63.2%, with an average location error of 8.94 m (SD = 8.55. GPS performance in riparian habitats was principally affected by water submersion and secondarily by GPS inclination and position within the riverbed. Temporal and spatial correlations of location estimates accounted for some variation in the data sets. GPS-tagged otters also provided accurate locations and an even higher GPS fix-success rate (68.2%. CONCLUSIONS/SIGNIFICANCE: Our results suggest that GPS telemetry is reliably applicable to riparian and even diving freshwater animals. They also highlight the need, in GPS wildlife studies, for performing site-specific pilot studies on GPS functioning as well as for taking into account eventual spatial and temporal correlation of location estimates. The limited price, small dimensions, and high performance of the device presented here make it a useful and cost-effective tool for studies on otters and other aquatic or

  11. Wearable Health Monitoring Systems

    Bell, John

    2015-01-01

    The shrinking size and weight of electronic circuitry has given rise to a new generation of smart clothing that enables biological data to be measured and transmitted. As the variation in the number and type of deployable devices and sensors increases, technology must allow their seamless integration so they can be electrically powered, operated, and recharged over a digital pathway. Nyx Illuminated Clothing Company has developed a lightweight health monitoring system that integrates medical sensors, electrodes, electrical connections, circuits, and a power supply into a single wearable assembly. The system is comfortable, bendable in three dimensions, durable, waterproof, and washable. The innovation will allow astronaut health monitoring in a variety of real-time scenarios, with data stored in digital memory for later use in a medical database. Potential commercial uses are numerous, as the technology enables medical personnel to noninvasively monitor patient vital signs in a multitude of health care settings and applications.

  13. Benzene Monitor System report

    Livingston, R.R.

    1992-10-12

    Two systems for monitoring benzene in aqueous streams have been designed and assembled by the Savannah River Technology Center, Analytical Development Section (ADS). These systems were used at TNX to support sampling studies of the full-scale {open_quotes}SRAT/SME/PR{close_quotes} and to provide real-time measurements of benzene in Precipitate Hydrolysis Aqueous (PHA) simulant. This report describes the two ADS Benzene Monitor System (BMS) configurations, provides data on system operation, and reviews the results of scoping tests conducted at TNX. These scoping tests will allow comparison with other benzene measurement options being considered for use in the Defense Waste Processing Facility (DWPF) laboratory. A report detailing the preferred BMS configuration statistical performance during recent tests has been issued under separate title: Statistical Analyses of the At-line Benzene Monitor Study, SCS-ASG-92-066. The current BMS design, called the At-line Benzene Monitor (ALBM), allows remote measurement of benzene in PHA solutions. The authors have demonstrated the ability to calibrate and operate this system using peanut vials from a standard Hydragard{trademark} sampler. The equipment and materials used to construct the ALBM are similar to those already used in other applications by the DWPF lab. The precision of this system ({+-}0.5% Relative Standard Deviation (RSD) at 1 sigma) is better than the purge & trap-gas chromatograpy reference method currently in use. Both BMSs provide a direct measurement of the benzene that can be purged from a solution with no sample pretreatment. Each analysis requires about five minutes per sample, and the system operation requires no special skills or training. The analyzer`s computer software can be tailored to provide desired outputs. Use of this system produces no waste stream other than the samples themselves (i.e. no organic extractants).

  14. Eavesdropping on GSM: state-of-affairs

    Broek, Fabian van den

    2011-01-01

    In the almost 20 years since GSM was deployed several security problems have been found, both in the protocols and in the - originally secret - cryptography. However, practical exploits of these weaknesses are complicated because of all the signal processing involved and have not been seen much outside of their use by law enforcement agencies. This could change due to recently developed open-source equipment and software that can capture and digitize signals from the GSM frequencies. This might make practical attacks against GSM much simpler to perform. Indeed, several claims have recently appeared in the media on successfully eavesdropping on GSM. When looking at these claims in depth the conclusion is often that more is claimed than what they are actually capable of. However, it is undeniable that these claims herald the possibilities to eavesdrop on GSM using publicly available equipment. This paper evaluates the claims and practical possibilities when it comes to eavesdropping on GSM, using relatively che...

  17. Modified TEM cell design exposure system for in vitro exposure of cultured human astrocytes to 900 MHz GSM mobile phone type signals

    Full text: A key to the rigour of any experiment seeking to investigate possible effects on living systems of the electromagnetic energy (EME) from mobile phones is to ensure that the exposures used are accurately known and reflect the actual exposures. To achieve well controlled and characterised radiofrequency (RF) exposures is not trivial, and has been a concern in many previous studies. At St Vincent's Hospital Centre for Immunology (CFI), an in vitro study is being performed of possible gene expression changes in cultured human astrocytes exposed to GSM mobile phone type signals. In order to provide rigorous RF dosimetry for the study, Telstra Research Laboratories (TRL) has developed a modified transverse electromagnetic (TEM) cell exposure system. This paper will describe salient aspects of the design and development of the system used at CFI. In the experimental design proposed by CFI, live human astrocyte cells are exposed in standard FalconTM 25 cm3 plastic culture flasks while incubated in a CO2 atmosphere at 37 deg C. The cells typically exist as a very thin monolayer (microns) adhered to the bottom of the flask under a layer of several millimetres of nutrient media. This particular arrangement presents a number of challenges for the design of an appropriate RF exposure system. Many RF exposure systems rely on measurements of average absorption within the target material to determine the specific absorption rate (SAR) in the sample. The actual SAR at any given point in the exposed volume may differ markedly from this average value, and typically varies quadratically with height (h) within the sample, where h is taken to be in the direction of the incident electric (E) field. This variance may be tolerable where the cells are distributed in solution throughout the volume, but this is not the case in this instance. Alternatively, keeping the sample very thin can reduce the variance. However, this limits the efficiency of the system, so that high input

  18. Indoor Localisation Based on GSM Signals: Multistorey Building Study

    Rafał Górak

    2016-01-01

    Full Text Available Among the accurate indoor localisation systems that are using WiFi, Bluetooth, or infrared technologies, the ones that are based on the GSM rely on a stable external infrastructure that can be used even in an emergency. This paper presents an accurate GSM indoor localisation system that achieves a median error of 4.39 metres in horizontal coordinates and up to 64 percent accuracy in floor prediction (for 84 percent of cases the floor prediction is mistaken by not more than a single floor. The test and reference measurements were made inside a six-floor academic building, with an irregular shape, whose dimensions are around 50 metres by 70 metres. The localisation algorithm uses GSM signal readings from the 7 strongest cells available in the GSM standard (or fewer, if fewer than 7 are available. We estimate the location by a three-step method. Firstly, we propose a point localisation solution (i.e., localisation based on only one measurement. Then, by applying the central tendency filters and the Multilayer Perceptron, we build a localisation system that uses a sequence of estimations of current and past locations. We also discuss major accuracy factors such as the number of observed signals or the types of spaces in the building.

  19. GSM-R International. Europe's railways growing closer together; GSM-R International. Europas Bahnen wachsen zusammen

    Pospischil, Reinhard [DB Netz AG, Muenchen (Germany). Internationale Kooperation GSM-R und Tk

    2010-07-01

    GSM-R, the digital radio communication system for railways, offers a uniform standard, which more and more railways throughout Europe are using. GSM-R is thus making a crucial contribution to bringing the railway systems closer together. The network operators are already cooperating with one another internationally at various levels in Europe with this aim in mind. The UIC's working groups have drawn up a standardised contract for setting up international roaming, but there are still numerous hurdles to overcome, despite the very considerable volume of work already done. In this context, it would be helpful if certifications of the individual GSM-R networks and their operating methods could be introduced in a binding fashion in accordance with the example laid down ISO 9002. New interfaces between the radio-equipment systems are coming into being at the border crossings between neighbouring infrastructure managers, where there has to be an adequately dimensioned overlapping zone between the networks, and switching from one network to another must be determined independently of the operational constraints of the particular border sections. Thanks to GSM-R, it is becoming possible in many instances to eliminate the communication gaps that have existed to date in handling train movements across borders and thus to make a contribution to the desired improvement in interoperability and operating control. In doing this, it is important above all else for the railway employees to feel at ease working with such systems too. (orig.)

  1. Design and testing of a GPS/GSM collar prototype to combat cattle rustling

    Francesco M. Tangorra

    2013-10-01

    Full Text Available Rustling is an age-old practice that was widespread in Italy until the first half of the 20th century. Today, incidents of cattle rustling are again being reported. However, the problem is not only found in Italy. It is also becoming a plague for ranchers in the US and is still rampant in East Africa. In Italy, the cattle rustling phenomena have usually been limited through the direct control of the herdsmen. Global positioning system (GPS and geographic information system (GIS combined technologies are increasingly applied for tracking and monitoring livestock with greater spatial and temporal resolution. However, so far, no case studies of the use of GPS technology to combat cattle rustling have been reported in the literature. The aim of this research was to develop a GPS/GSM (global system for mobile communication collar, using commercial hardware and implementing a specific software [ARVAshepherd 1.0; ARVAtec Srl, Rescaldina (MI, Italy] to track animals’ movements outside their grazing area and to signal when animals are straying outside virtual perimeters. A phase I study was conducted from January to June 2011 to build the GPS/GSM collar and to assess its performances in terms of GPS accuracy and precision, while a phase II study was conducted in July 2011 to test the GPS collar under real-life operating conditions. The static GPS positioning error achieved a circular error probable (50% and horizontal 95% accuracy of 1.462 m and 4.501 m, respectively. This is comparable with values obtained by other authors in static tests of a commercial GPS collar for grazing studies. In field tests, the system was able to identify the incorrect position of the cattle and the warning messages were sent promptly to the farmer, continuing until the animals had been repositioned inside the fence, thus highlighting the potential of the GPS/GSM collar as an anti-theft system.

  2. Bulk laundry monitoring system

    Protective wear (like boiler suits, hand gloves etc.) is essential while handling radioactive material in plants/laboratories. During the course of work, it is quite possible that protective wear may get contaminated. These protective wears are packed in laundry bags and send to Decontamination Centre (DC). There is a need for monitoring the laundry bags at the time of receipt, as well as before dispatch to respective locations to comply with AERB guidelines, To avoid cross contamination during wash cycle, contaminated bags (> 0.5 mR/h on surface) need to be segregated. Present paper describes the development of such system for monitoring surface dose rate on bags at the time of receipt. The system installed at ETP after calibration, effectively segregates the contaminated bags from the rest and prevents from cross contamination during wash cycle. Reduction in man-rem consumption due to semi automatic monitoring. Improved sensitivity due to good geometry, long counting time, background and attenuation corrections. Optimum utilization of decontamination chemicals based on level of contamination and keeping track of its inventory. Generation of decontamination process data base for improvement

    The paper presents the results of numerical calculations of lightning surge currents and voltages in the low voltage power mains system connected to a free standing GSM base station. Direct lightning strike to GSM tower was studied. The analysis concerned the current that flows to the transformer station through AC power mains, the potential difference between the grounding systems of the GSM and the transformer stations and the voltage differences between phase and PE conductors of the power mains underground cable at both the GSM and the transformer sides. The calculations were performed using a numerical program based on the electromagnetic field theory and the method of moments. (author)

  4. Induced Seismicity Monitoring System

    Taylor, S. R.; Jarpe, S.; Harben, P.

    2014-12-01

    There are many seismological aspects associated with monitoring of permanent storage of carbon dioxide (CO2) in geologic formations. Many of these include monitoring underground gas migration through detailed tomographic studies of rock properties, integrity of the cap rock and micro seismicity with time. These types of studies require expensive deployments of surface and borehole sensors in the vicinity of the CO2 injection wells. Another problem that may exist in CO2 sequestration fields is the potential for damaging induced seismicity associated with fluid injection into the geologic reservoir. Seismic hazard monitoring in CO2 sequestration fields requires a seismic network over a spatially larger region possibly having stations in remote settings. Expensive observatory-grade seismic systems are not necessary for seismic hazard deployments or small-scale tomographic studies. Hazard monitoring requires accurate location of induced seismicity to magnitude levels only slightly less than that which can be felt at the surface (e.g. magnitude 1), and the frequencies of interest for tomographic analysis are ~1 Hz and greater. We have developed a seismo/acoustic smart sensor system that can achieve the goals necessary for induced seismicity monitoring in CO2 sequestration fields. The unit is inexpensive, lightweight, easy to deploy, can operate remotely under harsh conditions and features 9 channels of recording (currently 3C 4.5 Hz geophone, MEMS accelerometer and microphone). An on-board processor allows for satellite transmission of parameter data to a processing center. Continuous or event-detected data is kept on two removable flash SD cards of up to 64+ Gbytes each. If available, data can be transmitted via cell phone modem or picked up via site visits. Low-power consumption allows for autonomous operation using only a 10 watt solar panel and a gel-cell battery. The system has been successfully tested for long-term (> 6 months) remote operations over a wide range

  8. SMS service from your GSM mobile phone

    IT Department

    2009-01-01

    The exchange of SMS (Short Message Service) messages is a very popular application of GSM mobile services. However, the use of the application with a CERN subscription is subject to certain conditions: First of all, only text messages can be sent and received with a CERN GSM subscription. These messages are limited to 160 characters. MMS (Multimedia Message Service) messages, which consist in attaching pictures, videos or sounds to a message, are not supported by the current CERN mobile network configuration. In addition, value-added SMS or SMS premium messages (e.g. messages to short numbers involving extra charges) are not permitted. Before sending a message, you must first record the number of the message centre (+41765980000) in your mobile. In principle, this configuration setting is automatically applied to all standard GSM mobile phones when they are issued. To send a message to another GSM user, you must of course enter his or her GSM number. This number must be e...

    2014-06-01

    Full Text Available Drip irrigation is now a common phenomenon gaining popularity especially in the states like Rajasthan where water scarcity is a day to day affair. For drip irrigation a small over head water tank in used which supply water to the drip system. Usually the geographic systems as well as the cost do not permit a bigger tank. This tank generally gets vacated and a farmer needs to be always attentive to refill the over head tank from his well or cannel by an electric pump, mostly this need arises in the night as the availability of power is not whole day. This involved a lot of risk and cost on the part of farmer. The simple and low cost gadget that has been work upon, not only control the starting and stopping of motor by sending a simple SMS through a GSM mobile but also gets the return SMS showing level of water in overhead tank. The application of the gadget is not only limited to the use for a farmer & but can be beneficial for any process industry in which level of a chemical or any liquid need to be crucially controlled and monitored from far end, may be even from the home of a supervisor with no constraints of time or place for controlling the operations.

    2011-06-01

    The integration of communication technologies such as radio frequency identification (RFID), global positioning system (GPS), general packet radio system (GPRS), and geographic information system (GIS) with a camera are constructed for solid waste monitoring system. The aim is to improve the way of responding to customer's inquiry and emergency cases and estimate the solid waste amount without any involvement of the truck driver. The proposed system consists of RFID tag mounted on the bin, RFID reader as in truck, GPRS/GSM as web server, and GIS as map server, database server, and control server. The tracking devices mounted in the trucks collect location information in real time via the GPS. This information is transferred continuously through GPRS to a central database. The users are able to view the current location of each truck in the collection stage via a web-based application and thereby manage the fleet. The trucks positions and trash bin information are displayed on a digital map, which is made available by a map server. Thus, the solid waste of the bin and the truck are being monitored using the developed system. PMID:20703798

  18. A GPS-based Real-time Road Traffic Monitoring System

    Tanti, Kamal Kumar

    In recent years, monitoring systems are astonishingly inclined towards ever more automatic; reliably interconnected, distributed and autonomous operation. Specifically, the measurement, logging, data processing and interpretation activities may be carried out by separate units at different locations in near real-time. The recent evolution of mobile communication devices and communication technologies has fostered a growing interest in the GIS & GPS-based location-aware systems and services. This paper describes a real-time road traffic monitoring system based on integrated mobile field devices (GPS/GSM/IOs) working in tandem with advanced GIS-based application software providing on-the-fly authentications for real-time monitoring and security enhancement. The described system is developed as a fully automated, continuous, real-time monitoring system that employs GPS sensors and Ethernet and/or serial port communication techniques are used to transfer data between GPS receivers at target points and a central processing computer. The data can be processed locally or remotely based on the requirements of client’s satisfaction. Due to the modular architecture of the system, other sensor types may be supported with minimal effort. Data on the distributed network & measurements are transmitted via cellular SIM cards to a Control Unit, which provides for post-processing and network management. The Control Unit may be remotely accessed via an Internet connection. The new system will not only provide more consistent data about the road traffic conditions but also will provide methods for integrating with other Intelligent Transportation Systems (ITS). For communication between the mobile device and central monitoring service GSM technology is used. The resulting system is characterized by autonomy, reliability and a high degree of automation.

    The data service on GSM subscriptions has been improved, allowing CERN users to access the Internet directly. A CERN GSM subscription with data option now allows you to connect to the Internet from a mobile phone or a PC equipped with a GSM modem. The previous access (CERN intranet) still exists. To get access to the new service, you will find all the information on configurations at: http://cern.ch/gprs The use of this service on the Sunrise network is charged on a flat-rate basis (no extra charge related to the volume of downloaded data). Depending on your CERN subscription type (standard or master), you can also connect to foreign GSM data networks (roaming), but this is strongly discouraged, except where absolutely necessary, due to international roaming charges.

  12. Unattended Monitoring System Design Methodology

    A methodology for designing Unattended Monitoring Systems starting at a systems level has been developed at Sandia National Laboratories. This proven methodology provides a template that describes the process for selecting and applying appropriate technologies to meet unattended system requirements, as well as providing a framework for development of both training courses and workshops associated with unattended monitoring. The design and implementation of unattended monitoring systems is generally intended to respond to some form of policy based requirements resulting from international agreements or domestic regulations. Once the monitoring requirements are established, a review of the associated process and its related facilities enables identification of strategic monitoring locations and development of a conceptual system design. The detailed design effort results in the definition of detection components as well as the supporting communications network and data management scheme. The data analyses then enables a coherent display of the knowledge generated during the monitoring effort. The resultant knowledge is then compared to the original system objectives to ensure that the design adequately addresses the fundamental principles stated in the policy agreements. Implementation of this design methodology will ensure that comprehensive unattended monitoring system designs provide appropriate answers to those critical questions imposed by specific agreements or regulations. This paper describes the main features of the methodology and discusses how it can be applied in real world situations

    2011-01-01

    All over the world the peak demand load is increasing and the load factor is decreasing year-by-year. The fossil fuel is considered insufficient thus solar energy systems are becoming more and more useful, not only in terms of installation but monitoring of these systems is very crucial. Monitoring becomes very important when there are a large number of solar panels. Monitoring would allow early detection if the output falls below required level or one of the solar panel out of 1000 goes down. In this study the target is to monitor and control a developed solar panel by using available internet foundation. This web-enabled software will provide more flexibility over the system such as transmitting data from panel to the host computer and disseminating information to relevant stake holders barring any geographical barrier. The software would be built around web server with dynamic HTML and JAVA, this paper presents the preliminary design of the proposed system.

    This paper presents a web-based Job Monitoring framework for individual Grid sites that allows users to follow in detail their jobs in quasi-real time. The framework consists of several independent components: (a) a set of sensors that run on the site CE and worker nodes and update a database, (b) a simple yet extensible web services framework and (c) an Ajax powered web interface having a look-and-feel and control similar to a desktop application. The monitoring framework supports LSF, Condor and PBS-like batch systems. This is one of the first monitoring systems where an X.509 authenticated web interface can be seamlessly accessed by both end-users and site administrators. While a site administrator has access to all the possible information, a user can only view the jobs for the Virtual Organizations (VO) he/she is a part of. The monitoring framework design supports several possible deployment scenarios. For a site running a supported batch system, the system may be deployed as a whole, or existing site sensors can be adapted and reused with the web services components. A site may even prefer to build the web server independently and choose to use only the Ajax powered web interface. Finally, the system is being used to monitor a glideinWMS instance. This broadens the scope significantly, allowing it to monitor jobs over multiple sites.

  14. Network management convergence of multiple subnetworks in GSM infrastructure

    Zong, Baiqing; Su, Jiang; Zhong, Tao; Dong, Hui; Zhong, Shuangli; Zhou, Weiming; Chen, Wansheng

    2001-10-01

    Network convergence, including service, timing and management convergence, is a trend of future telecommunication networks. Because network convergence can provide carriers with cost reduction, highly integrated applications as well as greater flexibility and functionality, new technologies and standards have driven this convergence tide. However, network management convergence, managing disparate networks with a unified platform, has been a challenging task in sophisticated telecommunication network environments. Administrators are faced with the task of managing various devices with several different applications, without an effective tool set to provide visibility across the network. In general, multiple transmission networks such as SDH, PON, HDSL and digital microwave are adopted in GSM infrastructure to transport mobile traffic between BTS and BSC. Traditional method of managing these devices is that GSM network (MSC, BSC and BTS), SDH, PON, HDSL and digital microwave are managed independently. In this paper, a converged network management platform, named OMConvergence, is proposed and demonstrated. The platform aims at managing the whole GSM network covering SDH, PON, HDSL or digital microwave sub-networks within it. The OMConvergence comprises of remote access methods of OAM message, as well as processing of multiple network management protocol such as ECC (Embedded Control Channel), Q3 and simple network management protocol (SNMP). The management and maintenance message of various devices physically converges to E1 timeslots at the sides of BTS, and then convert to unified IP packages before it is terminated at the side of BSC or network administration center. In addition, extended applications of OMConvergence in image monitoring of BTS surroundings are also demonstrated.

  15. Monitoring the DIRAC distributed system

    Santinelli, R; Nandakumar, R

    2010-01-01

    DIRAC, the LHCb community Grid solution, is intended to reliably run large data mining activities. The DIRAC system consists of various services (which wait to be contacted to perform actions) and agents (which carry out periodic activities) to direct jobs as required. An important part of ensuring the reliability of the infrastructure is the monitoring and logging of these DIRAC distributed systems. The monitoring is done collecting information from two sources – one is from pinging the services or by keeping track of the regular heartbeats of the agents, and the other from the analysis of the error messages generated both by agents and services and collected by a logging system. This allows us to ensure that the components are running properly and to collect useful information regarding their operations. The process status monitoring is displayed using the SLS sensor mechanism that also automatically allows to plot various quantities and keep a history of the system. A dedicated GridMap interface (Service...

  17. Heater drain system transient monitoring

    Feedwater heater drain systems are susceptible to unstable, two phase flow conditions. These instabilities are difficult to predict and are dependent on plant-specific system designs and operating conditions. Therefore, significant vibrations and transient events can occur that the systems are not specifically designed for. This paper describes how heater drain system responses due to unanticipated transient events at a nuclear plant were captured and quantified using a digital data acquisition system. The setup of the data acquisition system, including the determination of what parameters to monitor and how to effectively capture potential transient events, is discussed. This paper also discusses the monitoring results and their relevance to system modification evaluations and root cause evaluations

  18. A Novel Radiation Monitoring System

    An ultra reliable radiation monitoring system is essential in order to provide safety to the workers in nuclear plants. The system should be able to detect minor fluctuations of the radiation field and activate an alarm when file radiation field exceeds predefined thresholds. The system implementation requires qualification for nuclear applications such as IEEE 323 and IEC 61503. In this paper such system is presented, it is a novel modular system that provides reliable monitoring of y radiation field. Although such systems were developed in the past, the presented system is based on modern electronics and 'went file extra mile' to provide a very high reliability achieved by using sophisticated methods of BIT (Built In Test) and feedback loops

  19. Analysis of Data Transmission Method based on GSM-R Network and Teaching Platform For Wireless Network

    2013-07-01

    Full Text Available Railway digital radio system, GSM-R, is a dedicated system for railway based on GSM system, which shoulders the demand of dedicated dispatching communication for railway. So it is extremely important to research the data transmission of GSM-R. In this paper, a data transmission method has been proposed, based on the actual measurement report of GSM-R and a prediction algorithm, in analyzing the relationship between Measurement Report and Transmission Interference through visualization method by using the data mining instruments. The simulation results prove that the probability of data being interrupted and retransmitted can be decreased by using this method. At the same time, a teaching platform is established for analyzing the actual test data and the simulation in high-speed railway system, which can contribute to the theoretical research and the teaching. And the mass data used in this paper comes from this platform.  

  20. Evaluation of Radiation Monitoring System

    As a part of the continuous improvement policy of the NRCN, a novel radiation monitoring system is being developed. The challenge in developing such a system is to assure that the system provides safety improvement. In order to achieve this goal, a set of parameters was defined to estimate the safety performance of the current system. The values of these parameters will be used as a reference for a comparison between the current system and the developed one. This paper describes the method for evaluating the defined parameters: stability and accuracy of the ionization current and the response time of the system

  2. GTA Beamloss-Monitor System

    The GTA Beamless-Monitor System at Los Alamos National Laboratory has been designed to detect high-energy particle loss in the accelerator beamline and shut down the accelerator before any damage can occur. To do this, the Beamless-Monitor System measures the induced gamma radiation, from (p, γ) reactions, at 15 selected points along the beamline, converts this measured radiation to electrical signals integrates and compares them to preset limits, and, in the event of an over-limit condition causes the Fast-Protect System to shut down the entire accelerator. The system dynamic range exceeds 70 dB which will enable experimenters to use the Beamless-Monitor System to help steer the beam as well as provide signals for a Fast-Protect System. The system response time is less than 7 μs assuming a step-function, worst-case beam spill of 50 mA. The system resolution, based on the noise floor of the electronics is about 1.3 mRads/s. Production units have been built and meet the above specifications. The remainder of the system will be installed and tested later in 1992/1993 with the GTA accelerator. The ionization chamber sensitivity and response time are described in the paper

    Price, Danny C.

    2016-03-01

    PyGSM is a Python interface for the Global Sky Model (GSM, ascl:1011.010). The GSM is a model of diffuse galactic radio emission, constructed from a variety of all-sky surveys spanning the radio band (e.g. Haslam and WMAP). PyGSM uses the GSM to generate all-sky maps in Healpix format of diffuse Galactic radio emission from 10 MHz to 94 GHz. The PyGSM module provides visualization utilities, file output in FITS format, and the ability to generate observed skies for a given location and date. PyGSM requires Healpy, PyEphem (ascl:1112.014), and AstroPy (ascl:1304.002).

    Aim: To evaluate the effects of global system for mobile communications (GSM)1800 MHz microwaves on dendritic filopodia, dendritic arborization, and spine maturation during development in cultured hippocampal neurons in rats. Methods: The cultured hippocampal neurons were exposed to GSM 1800 MHz microwaves with 2.4 and 0.8 W/kg, respectively, for 15 min each day from 6 days in vitro (DIV6) to DIV14. The subtle structures of dendrites were displayed by transfection with farnesylated enhanced green fluorescent protein (F-GFP) and GFP-actin on DIV5 into the hippocampal neurons. Results: There was a significant decrease in the density and mobility of dendritic filopodia at DIV8 and in the density of mature spines at DIV14 in the neurons exposed to GSM 1800 MHz microwaves with 2.4 W/kg. In addition, the average length of dendrites per neuron at DIV10 and DIV14 was decreased, while the dendritic arborization was unaltered in these neurons. However, there were no significant changes found in the neurons ex- posed to the GSM 1800 MHz microwaves with 0.8 W/kg. Conclusion: These data indicate that the chronic exposure to 2.4 W/kg GSM 1800 MHz micro- waves during the early developmental stage may affect dendritic development and the formation of excitatory synapses of hippocampal neurons in culture.

  11. Complementary neutron flux monitoring system

    The present work is an example for that, how with modern technical instruments it is possible to compensate disadvantage and to increase technical resources of the old systems, without a change of given system totally with new one. The system detail design and implementation was possible mostly, due to the international conferences and courses organized by IAEA and technical information provided by the agency. The system acts as a complementary to the existing systems for the reactor core neutron flux monitoring AKNP. The new system extends the measurement range of the original AKNP system approximately by two decades. It allows neutron flux to be monitored during refuelling. The system is permitted for use by Bulgarian Nuclear Safety Authority - CUAEPP. The system also calculates the reactivity and thus allows the operator to monitor the criticality condition very precisely. The system calculates also the period of the reactor and has adjustable setpoints at two levels for alarm and pre-alarm, both for counting rate and period. The system sends the analog signals for the counting rate and for the period as well as digital signals for the alarm and pre-alarm to the refueling machine cabin for on-line control. It also produces sound and blinks (LEDs) if any setpoint is reached. It should be mentioned that the refueling machine panel do not need additional power supply and thus high reliability is achieved. The system automatically stores the data for neutron flux, period, reactivity, alarm and prealarm state and value, reactor kinetic parameters(β,λ and source) on hard disk. The stored data can be reviewed very easy and printed. Depending on the hard disk capacity the storage period can be longer than a year. The old system for neutron flux monitoring during refuelling, which operated with 3 removable neutron fission chambers KNT-54 located next to the reactor core is now obsolete and is decommissioned. This have the significant impact on personnel dose

  14. Efficient Radio Resource Allocation in a GSM and GPRS Cellular Network

    David Vannucci

    2004-10-01

    Full Text Available This paper investigates the effect of various radio resource allocation strategies in a GSM/GPRS cellular network. The most efficient resource allocation is analysed as a function of the proportion of circuit switched voice and packet switched data load. The Grade of Service and average packet delay is investigated as a function of the load, packet size and call duration. Additionally, the feasibility of using voice over Internet Protocol as opposed to circuit switched voice is investigated as a means to increase subscriber capacity per base station. The work is motivated firstly by the complexity of having both circuit switched and packet switched connectivity on GSM/GPRS mobile cellular system and secondly that an exclusively packet based access on GSM/GPRS has the potential to increase the efficiency of resource utilisation by suitably varying the channel allocation to exploit the characteristics of voice and data traffic.

  17. Corral Monitoring System assessment results

    This report describes the results of a functional and operational assessment of the Corral Monitoring Systems (CMS), which was designed to detect and document accountable items entering or leaving a monitored site. Its development was motivated by the possibility that multiple sites in the nuclear weapons states of the former Soviet Union might be opened to such monitoring under the provisions of the Strategic Arms Reduction Treaty. The assessment was performed at three levels. One level evaluated how well the planned approach addressed the target application, and which involved tracking sensitive items moving into and around a site being monitored as part of an international treaty or other agreement. The second level examined the overall design and development approach, while the third focused on individual subsystems within the total package. Unfortunately, the system was delivered as disassembled parts and pieces, with very poor documentation. Thus, the assessment was based on fragmentary operating data coupled with an analysis of what documents were provided with the system. The system design seemed to be a reasonable match to the requirements of the target application; however, important questions about site manning and top level administrative control were left unanswered. Four weaknesses in the overall design and development approach were detected: (1) poor configuration control and management, (2) inadequate adherence to a well defined architectural standard, (3) no apparent provision for improving top level error tolerance, and (4) weaknesses in the object oriented programming approach. The individual subsystems were found to offer few features or capabilities that were new or unique, even at the conceptual level. The CMS might possibly have offered a unique combination of features, but this level of integration was never realized, and it had no unique capabilities that could be readily extracted for use in another system

  20. On the mechanisms of interference between mobile phones and pacemakers: parasitic demodulation of GSM signal by the sensing amplifier

    The aim of this study was to investigate the mechanisms by which the radiated radiofrequency (RF) GSM (global system for mobile communication) signal may affect pacemaker (PM) function. We measured the signal at the output of the sensing amplifier of PMs with various configurations of low-pass filters. We used three versions of the same PM model: one with a block capacitor which short circuits high-frequency signals; one with a ceramic feedthrough capacitor, a hermetically sealed mechanism connecting the internal electronics to the external connection block, and one with both. The PMs had been modified to have an electrical shielded connection to the output of the sensing amplifier. For each PM, the output of the sensing amplifier was monitored under exposure to modulated and non-modulated RF signals, and to GSM signals (900 and 1800 MHz). Non-modulated RF signals did not alter the response of the PM sensing amplifier. Modulated RF signals showed that the block capacitor did not succeed in short circuiting the RF signal, which is somehow demodulated by the PM internal non-linear circuit elements. Such a demodulation phenomenon poses a critical problem because digital cellular phones use extremely low-frequency modulation (as low as 2 Hz), which can be mistaken for normal heartbeat

  1. Semantic remote patient monitoring system.

    Shojanoori, Reza; Juric, Radmila

    2013-02-01

    We propose an automated and personalized remote patient monitoring (RPM) system, which is applied to care homes and is dependent on the manipulation of semantics describing situations during patient monitoring in ontological models. Decision making in RPM is based on reasoning performed upon ontologies, which secures the delivery of appropriate e-health services in care homes. Our working experiment shows an example of preventive e-healthcare, but it can be extended to any situation that requires either urgent action from healthcare professionals or a simple recommendation during RPM. We use Semantic Web technology and OWL/SWRL-enabled ontologies to illustrate the proposal and feasibility of implementing this RPM system as a software solution in pervasive healthcare. It will be of interest to healthcare professionals, who can directly shape and populate the proposed ontological model, and software engineers, who would consider using OWL/SWRL when creating e-health services in general.

    Full Text Available Using Wireless Sensor Networks (WSNs in health care system has yielded a tremendous effort in recent years. However, in most of these researches, tasks like sensor data processing, health state decisions making and emergency messages sending are completed by a remote server. Transmitting and handing with a large scale of data from body sensors consume a lot of communication resource, bring a burden to the remote server and delay the decision time and notification time. In this paper, we present a prototype of a smart gateway that we have implemented. This gateway is an interconnection and services management platform especially for WSN health care systems at home environment. By building a bridge between a WSN and public communication networks, and being compatible with an onboard data decision system and a lightweight database, our smart gateway system is enabled to make patients' health state decisions in low-power and low-cost embedded system and get faster response time o the emergencies. We have also designed the communication protocols between WSN, gateway and remote servers. Additionally Ethernet, Wi-Fi and GSM/GPRS communication module are integrated into the smart gateway in order to report and notify information to care-givers.

  7. Experimental and numerical assessment of low-frequency current distributions from UMTS and GSM mobile phones

    The evaluation of the exposure from mobile communication devices requires consideration of electromagnetic fields (EMFs) over a broad frequency range from dc to GHz. Mobile phones in operation have prominent spectral components in the low-frequency (LF) and radio-frequency (RF) ranges. While the exposure to RF fields from mobile phones has been comprehensively assessed in the past, the LF fields have received much less attention. In this study, LF fields from mobile phones are assessed experimentally and numerically for the global system for mobile (GSM) and universal mobile telecommunications system (UMTS) communication systems and conclusions about the global (LF and RF) EMF exposure from both systems are drawn. From the measurements of the time-domain magnetic fields, it was found that the contribution from the audio signal at a normal speech level, i.e., −16 dBm0, is the same order of magnitude as the fields induced by the current bursts generated from the implementation of the GSM communication system at maximum RF output level. The B-field induced by currents in phones using the UMTS is two orders of magnitude lower than that induced by GSM. Knowing that the RF exposure from the UMTS is also two orders of magnitude lower than from GSM, it is now possible to state that there is an overall reduction of the exposure from this communication system.

    de Aguiar, Alexei Barbosa; Neto, Alvaro de Menezes S; Cunha, Ruddy P P; Pinheiro, Rebecca F

    2009-01-01

    GSM networks are very expensive. The network design process requires too many decisions in a combinatorial explosion. For this reason, the larger is the network, the harder is to achieve a totally human based optimized solution. The BSC (Base Station Control) nodes have to be geographically well allocated to reduce the transmission costs. There are decisions of association between BTS and BSC those impacts in the correct dimensioning of these BSC. The choice of BSC quantity and model capable of carrying the cumulated traffic of its affiliated BTS nodes in turn reflects on the total cost. In addition, the last component of the total cost is due to transmission for linking BSC nodes to MSC. These trunks have a major significance since the number of required E1 lines is larger than BTS to BSC link. This work presents an integer programming model and a computational tool for designing GSM (Global System for Mobile Communications) networks, regarding BSS (Base Station Subsystem) with optimized cost.

    A platform built around three information entities (patient, health-care_agent, and central_station) was designed to enable patients with chronic heart disease (in stable condition; emergency situations were excluded deliberately) to complete specifically defined protocols for out-of-hospital follow-up and monitoring. The patients belonged to one of four specific risk groups: arterial hypertension, malignant arrhythmias, heart failure, and postinfarction rehabilitation. They were provided with portable recording equipment and a cellular phone that supported data transmission [electrocardiogram (ECG)] and wireless application protocol (WAP) (remaining parameters and ad hoc questionnaires). The central station was an automatized platform, with no human operator. The information received was organized chronologically in patient folders. The health-care_agents had continuous and secure access to the patient folders, through tools based on the world wide web and WAP, and to short messages sent by their patients. A pilot project was conducted with 89 patients (mean length of participation: 50.1 days). A total of 2168 ECGs (mean duration transmission = 2 min/30 s; network errors failures < 0.1%) were The functionality of the platform was also evaluated, analyzing the subjective component of usability, showing the evolution of patient acceptance over time.

  1. An Analytic Approach for Calculating Frame Erasue Rate in Cellular GSM Networks

    Ahmed M. Alaa

    2013-11-01

    Full Text Available The Quality of Service (QoS of a GSM system is quantified in terms of Bit Error Rate (BER and Frame Erasure Rate (FER observed by the user. The problem of obtaining analytical expressions for BER and FER in a fading channel with multiple cochannel interferers (CCI is an extremely complex mathematical problem. The reason for this complexity is that the involvement of several GSM physical layer modules is required to obtain an expression for the probability of bit error. Besides, one needs to obtain the statistical properties of faded cochannel interferers in order to obtain the raw BER of GMSK modulation. Thus, error rate metrics are usually obtained by simulating the GSM physical layer rather than treating the problem analytically. A reliable interface between system and link level models can be obtained by evaluating the BER and FER in terms of the Signal-to-Interference Ratio (SIR analytically, instead of the pre-defined statistical mapping data usually used in literature. In this work, bounds on the uplink BER and FER are obtained for the GSM physical layer assuming a CCI limited system where both the desired and interference signals are subjected to Rayleigh fading. The analysis considers GMSK modulation, convolutional coding and Frequency Hopping.

    Bleom, H.; Colombo, R.; Gilliaert, D.; Tebaldi, P. (Joint Research Centre, Ispra (Italy))

    1990-01-01

    Large solar thermal systems, which are in direct competition with so-called classical heat or cold producing systems (as fuel burners, air conditioners, ...) show, at the same time similarities and major differences. The classical systems are factory-packaged and modular systems (consequently they have a rather high reliability), and are site mounted. Solar thermal systems, however, are location dependent designs based on factory-made components (each of them having well known characteristics, reliability and durability). These components have to be connected and dimensioned in order to optimize the energy output in relation to the financial investments, the overall system reliability and durability, and maintenance. The analysis and the evaluation of the level of success of each of the projects should be enlarged and assisted with an intercomparison of different similar projects, leading to more general conclusions about: the usefulness of solar systems; the performance, i.e. the solar fraction of systems; the functioning and reliability of components; the effectiveness of different control strategies; proposals for improvements in the design, dimensioning and control strategies of systems; the impact on employment and on the environment of the introduction of solar systems; and to develop the necessary tools to assess the replicability of the techniques applied, even extended to other climates. This whole task could be largely facilitated by the introduction of some level of uniformity for the evaluation of the projects, through format sheets and/or guidelines for each of the following items: description of the project; set up of the monitoring of the system; and presentation of the results. Each of these is discussed.

  13. Design and implementation of environmental monitoring system

    the RECODAL (remote controlled data logger) is a stand - alone system based on the 80 C 537 micro-controller. one of the main features of the RECODAL system is its flexibility to be interfaced to various types of sensors after suitable signal conditioning and stor ge of data coming from these sensors into its serial EEPROM. in this paper, the design of signal conditioning circuits for interfacing a set of sensors with the RECODAL system to measure a set of environmental parameters such as nuclear radiation, temperature, relative humidity of the air, absolute air pressure, direction of wind and its speed will be introduced with the experimental results. as it is intended to have the RECODAL devices in the surrounded field that may be far from the control room so, we developed accurate, friendly and powerful graphical user interface software (GUI) for remote controlling the RECODAL system . the aim of this GUI not only to visual the data being received by the Pc from the RECODAL and output this data to a format for further analysis, but also to full control the RECODAL system remotely through external modem using normal telephone lines or a dual-band GSM modem depends on the availability of the communication media. this GUI has also the ability to upload the new developed firmware which is required for 80 C 537 micro controller without affecting the data or the communication program . one of the advantages of this GUI is that it can communicate with the RECODAL through the serial port of the Pc too

  14. Exposure to GSM 900 MHz electromagnetic fields affects cerebral cytochrome c oxidase activity

    The world-wide and rapidly growing use of mobile phones has raised serious concerns about the biological and health-related effects of radio frequency (RF) radiation, particularly concerns about the effects of RFs upon the nervous system. The goal of this study was conducted to measure cytochrome oxidase (CO) levels using histochemical methods in order to evaluate regional brain metabolic activity in rat brain after exposure to a GSM 900 MHz signal for 45 min/day at a brain-averaged specific absorption rate (SAR) of 1.5 W/Kg or for 15 min/day at a SAR of 6 W/Kg over seven days. Compared to the sham and control cage groups, rats exposed to a GSM signal at 6 W/Kg showed decreased CO activity in some areas of the prefrontal and frontal cortex (infralimbic cortex, prelimbic cortex, primary motor cortex, secondary motor cortex, anterior cingulate cortex areas 1 and 2 (Cg1 and Cg2)), the septum (dorsal and ventral parts of the lateral septal nucleus), the hippocampus (dorsal field CA1, CA2 and CA3 of the hippocampus and dental gyrus) and the posterior cortex (retrosplenial agranular cortex, primary and secondary visual cortex, perirhinal cortex and lateral entorhinal cortex). However, the exposure to GSM at 1.5 W/Kg did not affect brain activity. Our results indicate that 6 W/Kg GSM 900 MHz microwaves may affect brain metabolism and neuronal activity in rats

  20. A novel security algorithm for gsm mobile

    Security is a crucial factor in the provision of secure mobile services. The rapid growth of harmful attacks has increased the need for higher security level, especially in the case of wireless networks. GSM security is proposed by A5/1 synchronous symmetric-key stream cipher. It has been revealed in (1), (2), and (3) that biased birthday attack, random subgraph attack and correlation attack, breach the security at the air interface. In this paper, we have proposed a high level security solution that incorporates a new Key setup routine and new feedback taps positions. We have shown that the proposed solution is more secure and efficient by simulating and application of different Statistical Tests for standard A5/1 and proposed A5/1 in MATLAB and comparing results.

    The Monitored Geologic Repository Operations Monitoring and Control System provides supervisory control, monitoring, and selected remote control of primary and secondary repository operations. Primary repository operations consist of both surface and subsurface activities relating to high-level waste receipt, preparation, and emplacement. Secondary repository operations consist of support operations for waste handling and treatment, utilities, subsurface construction, and other selected ancillary activities. Remote control of the subsurface emplacement operations, as well as, repository performance confirmation operations are the direct responsibility of the system. In addition, the system monitors parameters such as radiological data, air quality data, fire detection status, meteorological conditions, unauthorized access, and abnormal operating conditions, to ensure a safe workplace for personnel. Parameters are displayed in a real-time manner to human operators regarding surface and subsurface conditions. The system performs supervisory monitoring and control for both important to safety and non-safety systems. The system provides repository operational information, alarm capability, and human operator response messages during emergency response situations. The system also includes logic control to place equipment, systems, and utilities in a safe operational mode or complete shutdown during emergency response situations. The system initiates alarms and provides operational data to enable appropriate actions at the local level in support of emergency response, radiological protection response, evacuation, and underground rescue. The system provides data communications, data processing, managerial reports, data storage, and data analysis.

  6. Innovative portable radiation monitoring system

    A new generation of portable monitoring systems is presented. The system consists of RAM R-200, a portable gamma meter designed for measuring wide range gamma radiation fields, and external probes for beta-gamma contamination, and high range gamma fields. The meter and the external probes were designed to withstand vibrations, shocks and extreme temperature conditions. The meter is lightweight - less than 500 g, compact - 80 x 35 x 130 mm, with emphasis on ergonomic design and ease of operation. It contains an internal detector with two energy compensated GM tubes for gamma field measurement in the range of 0.1 μSv/h to 1 Sv/h, and flat energy response to gamma radiation from 60 keV to 1350 keV. Low power consumption techniques enable more than 100 hours of continuous operation with a single 9V standard battery. The meter and the high range gamma probe meet the IEC1017-1 and ANSI-N42 standards. The meter includes signal processing electronics and embedded microprocessor circuitry. Dedicated software for data processing was developed, enabling smoothed analog and digital readout and fast response. Additional functions include accumulated dose calculation, malfunction detection and appropriate alarm, dose rate and accumulated thresholds, serial RS-232 communication with the external probes or with a PC. The RAM R-200 supports the logging or dose-rate measurements and acquisition time into its internal backed-up memory. Due to the importance of the audible indication to the user of such system an intensive study was done. Two audible indication modes are available. A conventional mode based on a short 'chirp' every pulse measured and variable frequency mode according to the field intensity. In the latter mode the meter automatically normalizes the frequency response with the actual measured field. The meter and the external probes include an internal microcontroller circuitry, power supplies for the internal electronics and detector high voltage, and output signal

New exposure system for human studies on possible effects of low dose radio frequency electromagnetic fields of GSM and UMTS on central nervous processes; Neuartiges Expositionssystem fuer Humanstudien zu moeglichen Wirkungen hochfrequenter elektromagnetischer Felder von GSM und UMTS auf zentralnervoese Verarbeitungsprozesse im Niedrigdosis-Bereich

    Schmid, G. [ARC Seibersdorf Research GmbH, Seibersdorf (Austria); Kundi, M. [Medizinische Univ. Wien (Austria). Inst. fuer Umwelthygiene; Molla-Djafari, H. [Allgemeine Unfallversicherungsanstalt AUVA, Wien (Austria)

    2004-07-01

    A new exposure system for human studies on possible effects of radio frequency (RF) electromagnetic fields on central nervous processes was developed. The system consists of a signal generation unit, a headset with antennas, which is worn by the test subject and a control and monitoring software allowing double blind application of RF exposure. The headset can be worn similar as spectacles and allows the mounting of one antenna at the left and one antenna at the right side of the head. This design provides a constant relative position between the antennas and the head and therefore a minimum of variation of the exposure, even in case of movements of the test subject. Furthermore test subjects' restriction is minimised and the head surface remains accessible for application of EEG-electrodes. In order to reduce the weight to be carried by the test subject's head the entire headset is suspended from the ceiling by a special suspension unit, yielding a resulting effective weight to be carried of less than 80 g. Using suitable antennas the system can be used for head exposures in the frequency range from 400 MHz to 5 GHz. (orig.)

  20. Operation and maintenance of the TFTR grounding system

    The authors discuss how the Tokamak Fusion Test Reactor (TFTR) grounding system utilizes a single-point ground which is connected to the building perimeter ground. Wired to this single-point ground, via individual 500 MCM insulated cables, are: the vacuum vessel, four toroidal field coil cases/inner support structure quadrants, umbrella structure halves, substructure ring girder sections, radial beams and columns and diagnostic systems. A special Ground System Monitor (GSM) system was designed and installed which actively monitors each of the individual machine grounds. The GSM insures that grounds remain intact thus avoiding secondary grounds on any components which would form a ground loop. Upon an accidental connection of a secondary ground to any one component of TFTR, the GSM sounds a horn within the TFTR test cell, the test cell basement, and the data acquisition rooms which notifies personnel that a ground loop is present

  1. Storage monitoring systems for the year 2000

    Nilsen, C.; Pollock, R.

    1997-12-31

    In September 1993, President Clinton stated the US would ensure that its fissile material meet the highest standards of safety, security, and international accountability. Frequent human inspection of the material could be used to ensure these standards. However, it may be more effective and less expensive to replace these manual inspections with virtual inspections via remote monitoring technologies. To prepare for this future, Sandia National Laboratories has developed several monitoring systems, including the Modular Integrated Monitoring System (MIMS) and Project Straight-Line. The purpose of this paper is to describe a Sandia effort that merges remote monitoring technologies into a comprehensive storage monitoring system that will meet the near-term as well as the long-term requirements for these types of systems. Topics discussed include: motivations for storage monitoring systems to include remote monitoring; an overview of the needs and challenges of providing a storage monitoring system for the year 2000; an overview of how the MIMS and Straight-Line can be enhanced so that together they create an integrated and synergistic information system by the end of 1997; and suggested milestones for 1998 and 1999 to assure steady progress in preparing for the needs of 2000.

  3. Supervisory monitoring system in nuclear power plants

    Monitoring of a power plant is one of the essential tasks during operation and the computer-based implementations are nowadays seemingly quite mature. However, presently these are still not satisfactory enough to meet the high standards to the licensing requirements and they are mostly not truly integrated to the plant's design-based monitoring system. This is basically due to the robustness problem as the majority of the methods are not robust enough for the monitoring of the safety parameter set in a plant or intelligent supervision. Therefore, a supervisory monitoring system (SMS) in a plant is necessary to supervise the monitoring tasks: determining the objectives to be obtained and finding the means to support them. SMS deals with the changing plant status and the coordination of the information flow among the monitoring subunits. By means of these robustness and consistency in monitoring is achieved. The paper will give the guidelines of knowledge and data management techniques in a framework of robust comprehensive and coordinated monitoring which is presented as supervisory monitoring. Such a high level monitoring serves for consistent and immediate actions in fault situations while this particularly has vital importance in preventing imminent severe accidents next to the issues of recognition of the monitoring procedures for licensing and enhanced plant safety.

    2015-02-01

    Full Text Available Reducing the energy consumption and carbon footprint emissions to improve the global climate change has become the global concern. However, CO2 generated from the current mobile devices and infrastructure has increased. Many researchers intended to develop the communication systems with low energy-consumption technologies, called the green communication. This paper proposes a framework of the load balanced green access network supporting the GSM femtocell service. By using the USRP software-defined radio device, we can build a GSM femtocell base station by software configuration. Besides, the proposed network can also extend the coverage of base stations by integrating with radio over fiber technology. With the load balancer, the proposed green access network can accomplish low power consumption, high energy efficiency, and easy to maintain. The experimental results showed that it can effectively save 24% energy consumption for the overall network and meet the quality-of-service of user when the proposed framework is applied.

  13. Ultra sensitive sea water radioactivity monitoring system. Autonomous low power consumption equipped with wireless data communication

    Following the recognition of their usefulness by the States and the scientific community, the automatic water monitoring networks were developed again to be able to measure sea water. For that purpose they had to be fully autonomous, have low power consumption (solar panels power supply), use wireless communicating (satellite, GSM, Radio) and be very sensitive (few Bq/m3). It is important to note that radioactivity detection in sea has many constraints: The detection system sensitivity must be very high because of the dilution factor of the ocean. The analysis method has to be adapted: the detection of very low levels of artificial contamination is made difficult due to the natural radioactivity in seawater (i.e., more than 10 kBq of 40K/m3). The system has to be completely autonomous, 'wireless'. Additional conventional measuring probes must be connected to the system to increase its interest (pH, t deg, salinity, position, meteorology). The system maintenance must be very limited (1/year). Wind and corrosion resistance must be high. The probe must be installed on a buoy. Moreover, some improvements are needed to allow: Amplification Gain drifts due to NaI sensitivity to t deg to be compensated. Net peak area computation in a specific energy range. Interference correction to prevent false alarms due to natural radiation. Very long counting time. (author)

    Wai-Kit Wong

    2011-05-01

    Full Text Available Thermal monitoring is useful for revealing some serious electrical problems in a factory that oftengo undetected until a serious breakdown occurs. In factories, there are various types offunctioning machines to be monitored. When there is any malfunctioning of a machine, extra heatwill be generated which can be picked up by thermal camera for image processing andidentification purpose. In this paper, a new and effective omnidirectional machine conditionmonitoring system applying log-polar mapper, quaternion based thermal image correlator andmax-product fuzzy neural network classifier is proposed for monitoring machine condition in anomnidirectional view. With this monitoring system, it is convenient to detect and monitor theconditions of (overheat or not of more than one machines in an omnidirectional view captured byusing a single thermal camera. Log-polar mapping technique is used to unwarp omnidirectionalthermal image into panoramic form. Two classification characteristics namely: peak to sideloberatio (PSR and real to complex ratio of the discrete quaternion correlation output (p-value areapplied in the proposed machine condition monitoring system. Large PSR and p-value observe ina good match among correlation of the input thermal image with a particular reference image,while small PSR and p-value observe in a bad/not match among correlation of the input thermalimage with a particular reference image. Simulation results also show that the proposed system isan efficient omnidirectional machine monitoring system with accuracy more than 97%

  3. The Authenticated Tracking and Monitoring System (ATMS)

    The Authenticated Tracking and Monitoring System (ATMS) has been designed to address the need for global monitoring of the status and location of proliferation-sensitive items. Conceived to utilize the proposed Global Verification and Location System (GVLS) satellite link, ATMS could use the existing International Maritime Satellite commercial communication system until GVLS is operational. The ATMS concept uses sensor packs to monitor items and environmental conditions, collects a variety of event data through a sensor processing unit, and transmits the data to a satellite, which then sends data to ground stations. Authentication and encryption algorithms will be used to secure the data. A typical ATMS application would be to track and monitor the safety and security of a number of items in transit along a scheduled shipping route. This paper also discusses a proof-of-concept system demonstration

    2016-01-01

    Purpose Due to its role in learning, memory and in many neurodegenerative diseases, acetylcholinesterase (AChE) represents an interesting endpoint to assess possible targets of exposure to radiofrequency electromagnetic fields (RF-EMF) generated by mobile phones. We investigated possible alterations of enzymatic activity, gene and protein expression of AChE in neuronal-like cells exposed to a 1.8 GHz Global System for Mobile Communication (GSM) modulated signal (217-GSM). Materials and methods Rat PC12 cells were exposed for 24 h to 1.8 GHz 217-GSM signal. Specific adsorption rate (SAR) was 2 W/kg. AChE enzyme activity was assessed spectrophotometrically by Ellman's method, mRNA expression level was evaluated by real time polymerase chain reaction, and protein expression was assessed by Western blotting. Results AChE enzymatic activity increased of 1.4-fold in PC12 cells exposed to 217-GSM signal for 24 h, whilst AChE transcriptional or translational pathways were not affected. Conclusion Our results provide the first evidence of effects on AChE activity after in vitro exposure of mammalian cells to the RF-EMF generated by GSM mobile phones, at the SAR value 2 W/kg. The obtained evidence promotes further investigations on AChE as a possible target of RF-EMF and confirm the ability of 1.8 GHz 217-GSM signal to induce biological effects in different mammalian cells.

  9. A GSM-based surface meteorology network in service of improved African hydrological data assimilation and drought forecasting

    Wolf, A.; Falusi, J.; Caylor, K. K.; Sheffield, J.; Wood, E. F.

    2012-12-01

    The last few years have witnessed an explosion in consumer electronics, particularly mobile computing and telephony. This technological development has led to profound changes in (i) the cost of mobile computing platforms, (ii) the ubiquity of data connectivity, particularly in rural locales, and (iii) the knowledge gap for non-specialists to design, manufacture, and program electronics. Our group has developed a small, inexpensive, modular electronics platform that accomodates any number or flavor of sensors, coupled to a GSM transceiver to allow machine-to-machine communications of realtime meteorological data of hydrological relevance. This effort has particular import in Sub-Saharan Africa, where there is a pressing need for improved drought monitoring and forecasting, but a sparse surface meteorology which poorly constrains the forecast model. We present here our design of the sensor package and data architecture, as well as an implementation of the data assimilation system using the Princeton African Drought Monitor and Forecast system. It is shown that due to the relatively large uncertainties in the prior condition, that surface meteorological and soil moisture observations reduce posterior ensemble spread considerably with potential to extend the forecast horizon and be useful for taking action on emerging drought.

  13. Coupling GSM/ALE with ES-FEM-T3 for fluid-deformable structure interactions

    Wang, S.; Khoo, B. C.; Liu, G. R.; Xu, G. X.; Chen, L.

    2014-11-01

    In light of the effectiveness of the edge-based smoothed finite element method (ES-FEM-T3) and arbitrary Lagrangian-Eulerian gradient smoothing method (GSM/ALE) in, respectively, solving the pure solid and fluid flow problems using three-node triangular elements, they are coupled together in the present study to solve the more challenging fluid-deformable structure interaction (FSI) problems based on the weak coupling algorithm. Specifically, the fluid flow is tracked over the moving mesh with the well developed GSM/ALE and the transient response of the solid part is solved by the newly developed explicit ES-FEM-T3. The solutions from these two parts are “linked” together by the carefully formulated FSI coupling conditions on the FSI interface. Detailed procedures are summarized to illustrate the implementations of the GSM/ALE with ES-FEM-T3 in an FSI analysis. Three benchmarks are employed to validate the proposed coupled smoothed method in solving both transient and steady-state FSI problems. The mesh sensitivity analysis is further carried out showing that the results of an FSI system appear more sensitive to the change in the solid mesh as compared to the fluid mesh, thus suggesting a more refined mesh for the solid part. Another significant finding is that the present method can still produce reliable results even on the extremely distorted mesh near the FSI interface. The successful coupling GSM/ALE with ES-FEM-T3 for solving FSI problems serves as a good start for further implementing the family of smoothed methods in solving more complex cross-area problems.

  14. Moisture monitoring and control system engineering study

    During the past 50 years, a wide variety of chemical compounds have been placed in the 149 single-shell tanks (SSTS) on the Hanford Site. A concern relating to chemical stability, chemical control, and safe storage of the waste is the potential for propagating reactions as a result of ferrocyanide-oxidizer and organic-oxidizer concentrations in the SSTS. Propagating reactions in fuel-nitrate mixtures are precluded if the amounts of fuel and moisture present in the waste are within specified limits. Because most credible ignition sources occur near the waste surface, the main emphasis of this study is toward monitoring and controlling moisture in the top 14 cm (5.5 in.) of waste. The purpose of this engineering study is to recommend a moisture monitoring and control system for use in SSTs containing sludge and saltcake. This study includes recommendations for: (1) monitoring and controlling moisture in SSTs; (2) the fundamental design criteria for a moisture monitoring and control system; and (3) criteria for the deployment of a moisture monitoring and control system in hanford Site SSTs. To support system recommendations, technical bases for selecting and using a moisture monitoring and control system are presented. Key functional requirements and a conceptual design are included to enhance system development and establish design criteria

  15. Seismic monitoring system replacement at Temelin plant

    The VVER-1000 plants under construction at Temelin (Czech Republic) were designed with an automatic reactor trip system triggered on seismic peak accelerations. Within the plant I and C upgrade, Westinghouse designed a digital Seismic Monitoring System to be integrated in an Artificial Intelligence based Diagnostic and Monitoring System. The system meets the requirements of the emerging standards prepared by the US NRC on the basis of EPRI studies, which recommend a detailed data evaluation and a pre-shutdown plant inspection before orderly shutdown, if required, rather than immediate emergency shutdown. The paper presents the arguments about automatic trip, as discussed in an IAEA meeting attended by expert consultants from Japan, Russia, US and Eastern and Western Europe. It describes the system installed at Temelin, including the plant specific criteria for OBE exceedance. Finally it presents the capabilities and limitations of the integration into an overall Diagnostic and Monitoring System

  19. Preparedness for response to the challenges from orphan sources: nationwide environmental radiation mapping with state of the art monitoring systems

    Based on the various international reports on orphan sources, the potential for radiological emergencies in public domain is recognized as a cause of concern. To detect the presence of any such orphan sources and to strengthen the preparedness for response to any radiological emergencies in public domain, a nationwide radiation mapping programme was initiated in India. Various radiation monitoring systems, few of them integrated with Global Positioning System (GPS) installed in mobile monitoring vans were used for this purpose. This monitoring also helped in generating the base line dose rate data of the cities and also in demonstrating the methodology of environmental monitoring for locating the presence of orphan sources, if any. During the detailed monitoring of various cities of the country, different systems such as GSM based Radiation Monitoring System (GRaMS), Compact Radiation Monitoring system, Portable Mobile Gamma Spectrometry System, Gamma Tracer System etc. installed in a vehicle were made to continuously acquire the data at a varying rate from 10 sec to 1 minute acquisition time. These systems can measure dose rate in the range of 0.01 - 100 μGy h-1 and can detect 7.4 MBq (200 μCi) of 60Co and 25 MBq (675 μCi) of 137Cs from a distance of 5 metre. Average dose rate recorded during these environmental monitoring was 81 ± 07 nGy h-1 with a maximum of 210 ± 11 nGyh-1 at Bangalore (attributed to the presence of K-40). The digital topographic map and the data acquired from the radiation mapping are used to generate terrestrial radiation map. This radiation profile stored in the database can be used as reference while carrying out the impact assessment following any nuclear / radiological emergencies. These systems also help to tag the radiation levels along with positional coordinates online onto the GIS map of the area. GRaMS also demonstrated its capability for online transmission of the data to the centralized data acquisition Base Station located

    2013-01-01

    Full Text Available Mobility data has attracted the researchers for the past few years because of its rich context and spatiotemporal nature, where this information can be used for potential applications like early warning system, route prediction, traffic management, advertisement, social networking, and community finding. All the mentioned applications are based on mobility profile building and user trend analysis, where mobility profile building is done through significant places extraction, user’s actual movement prediction, and context awareness. However, significant places extraction and user’s actual movement prediction for mobility profile building are a trivial task. In this paper, we present the user similarity mining-based methodology through user mobility profile building by using the semantic tagging information provided by user and basic GSM network architecture properties based on unsupervised clustering approach. As the mobility information is in low-level raw form, our proposed methodology successfully converts it to a high-level meaningful information by using the cell-Id location information rather than previously used location capturing methods like GPS, Infrared, and Wifi for profile mining and user similarity mining.

  3. Computerized plutonium laboratory-stack monitoring system

    The Los Alamos Scientific Laboratory has recently designed and constructed a Plutonium Research and Development Facility to meet design criteria imposed by the United States Energy Research and Development Administration. A primary objective of the design criteria is to assure environmental protection and to reliably monitor plutonium effluent via the ventilation exhaust systems. A state-of-the-art facility exhaust air monitoring system is described which establishes near ideal conditions for evaluating plutonium activity in the stack effluent. Total and static pressure sensing manifolds are incorporated to measure average velocity and integrated total discharge air volume. These data are logged at a computer which receives instrument data through a multiplex scanning system. A multipoint isokinetic sampling assembly with associated instrumentation is described. Continuous air monitors have been designed to sample from the isokinetic sampling assembly and transmit both instantaneous and integrated stack effluent concentration data to the computer and various cathode ray tube displays. The continuous air monitors also serve as room air monitors in the plutonium facility with the primary objective of timely evacuation of personnel if an above tolerance airborne plutonium concentration is detected. Several continuous air monitors are incorporated in the ventilation system to assist in identification of release problem areas

  4. Monitoring the CMS strip tracker readout system

    The CMS Silicon Strip Tracker at the LHC comprises a sensitive area of approximately 200 m2 and 10 million readout channels. Its data acquisition system is based around a custom analogue front-end chip. Both the control and the readout of the front-end electronics are performed by off-detector VME boards in the counting room, which digitise the raw event data and perform zero-suppression and formatting. The data acquisition system uses the CMS online software framework to configure, control and monitor the hardware components and steer the data acquisition. The first data analysis is performed online within the official CMS reconstruction framework, which provides many services, such as distributed analysis, access to geometry and conditions data, and a Data Quality Monitoring tool based on the online physics reconstruction. The data acquisition monitoring of the Strip Tracker uses both the data acquisition and the reconstruction software frameworks in order to provide real-time feedback to shifters on the operational state of the detector, archiving for later analysis and possibly trigger automatic recovery actions in case of errors. Here we review the proposed architecture of the monitoring system and we describe its software components, which are already in place, the various monitoring streams available, and our experiences of operating and monitoring a large-scale system

  5. Monitoring system of ECCS injection system upon periodical inspection

    An ECCS reactor injection system is automatically monitored upon periodical inspection. That is, a memory device stores information of the stand-by state of the ECCS reactor injection system upon periodical inspection. A data input means inputs monitoring item data in the present state. A required monitoring target is designated by the input means. A judging means compares the data of the monitoring target with the stand-by state information successively, to judge whether or not the monitoring target is in a predetermined stand-by state. A display means displays the result of the judgment. In the present system thus constituted, since it can be automatically judged whether or not the ECCS reactor injection system, as a monitoring target, is in the predetermined stand-by state, it is possible to reduce the operator's burden and improve the safety.

    This system measures tritium on-line and collects tritium from a flowing inert gas stream. It separates the tritium from other non-hydrogen isotope contaminating gases, whether radioactive or not. The collecting portion of the system is constructed of various zirconium alloys called getters. These alloys adsorb tritium in any of its forms at one temperature and at a higher temperature release it as a gas. The system consists of four on-line getters and heaters, two ion chamber detectors, two collection getters, and two guard getters. When the incoming gas stream is valved through the on-line getters, 99.9% of it is adsorbed and the remainder continues to the guard getter where traces of tritium not collected earlier are adsorbed. The inert gas stream then exits the system to the decay chamber. Once the on-line getter has collected tritium for a predetermined time, it is valved off and the next online getter is valved on. Simultaneously, the first getter is heated and a pure helium purge is employed to carry the tritium from the getter. The tritium loaded gas stream is then routed through an ion chamber which measures the tritium activity. The ion chamber effluent passes through a collection getter that readsorbs the tritium and is removable from the system once it is loaded and is then replaced with a clean getter. Prior to removal of the collection getter, the system switches to a parallel collection getter. The effluent from the collection getter passes through a guard getter to remove traces of tritium prior to exiting the system. The tritium loaded collection getter, once removed, is analyzed by liquid scintillation techniques. The entire sequence is under computer control except for the removal and analysis of the collection getter.

  10. Acoustic emission monitoring of composite containment systems

    This paper considers two different types of composite containment system, and two different types of acoustic emission (AE) monitoring approach. The first system is a composite reinforced pressure vessel (CRPV) which is monitored both during construction and in-service using a broadband modal acoustic emission (MAE) technique. The second system is a membrane cargo containment system which is monitored using both a global as well as a local AE technique. For the CRPV, the damage assessment is concerned mainly with the integrity of the composite outer layer at the construction stage, and possible fatigue cracking of the inner steel liner at the in-service stage. For the membrane tank, the damage assessment is concerned with locating and quantifying any abnormal porosities that might develop in-service. By comparing and contrasting the different types of structural system and different monitoring approaches inferences are drawn as to what role AE monitoring could take in the damage assessment of other types of composite containment system. (Detailed technical data have not been included, due to client confidentiality constraints.)

  11. Diabetes Monitoring System Using Mobile Computing Technologies

    Mashael Saud Bin-Sabbar

    2013-03-01

    Full Text Available Diabetes is a chronic disease that needs to regularly be monitored to keep the blood sugar levels within normal ranges. This monitoring depends on the diabetic treatment plan that is periodically reviewed by the endocrinologist. The frequent visit to the main hospital seems to be tiring and time consuming for both endocrinologist and diabetes patients. The patient may have to travel to the main city, paying a ticket and reserving a place to stay. Those expenses can be reduced by remotely monitoring the diabetes patients with the help of mobile devices. In this paper, we introduce our implementation of an integrated monitoring tool for the diabetes patients. The designed system provides a daily monitoring and monthly services. The daily monitoring includes recording the result of daily analysis and activates to be transmitted from a patient’s mobile device to a central database. The monthly services require the patient to visit a nearby care center in the patient home town to do the medical examination and checkups. The result of this visit entered into the system and then synchronized with the central database. Finally, the endocrinologist can remotely monitor the patient record and adjust the treatment plan and the insulin doses if need.

  12. Reactivity monitoring in ADS systems

    Monitoring reactivity in an ADS should be performed on-line with a simple, accurate and robust technique. Within the range of experimental reactor techniques, no single technique can be selected which meet these requirements. Therefore a combination of different techniques has to be chosen in a way that various off-line techniques serve as a calibration for the on-line measurement technique. As an on-line measurement technique, the current/flux reactivity indicator is the most simple and robust solution. It is based on the fact that in a subcritical multiplying medium with a driving source the flux level is proportional to the driving source intensity, hence the beam current, and the reactivity level. However, since the proportionality constant depends on a number of core dependent parameters and detector characteristics, this current-to-flux indicator has to be calibrated on a regular basis. For this calibration, one could benefit from the occurrence of accelerator beam trips to determine the reactivity level in dollars by means of a prompt jump analysis of the flux level change. Hence, the prompt jump reactivity indicator could act as a first calibration tool of the current-to-flux indicator. Since the prompt jump indicator still relies on the value for the effective delayed neutron fraction to determine reactivity level, complementary techniques have to be used to obtain a more accurate determination of the reactivity. Techniques based on reactor noise methods such as RAPJA technique which is combination of the Rossi-alpha method and Prompt jump analysis can be used in this respect. In the future the bi-spectral ratio from the Cf - source driven noise analysis could be used for this purpose. (author)

  14. Reduced growth of soybean seedlings after exposure to weak microwave radiation from GSM 900 mobile phone and base station.

    Halgamuge, Malka N; Yak, See Kye; Eberhardt, Jacob L

    2015-02-01

    The aim of this work was to study possible effects of environmental radiation pollution on plants. The association between cellular telephone (short duration, higher amplitude) and base station (long duration, very low amplitude) radiation exposure and the growth rate of soybean (Glycine max) seedlings was investigated. Soybean seedlings, pre-grown for 4 days, were exposed in a gigahertz transverse electromagnetic cell for 2 h to global system for mobile communication (GSM) mobile phone pulsed radiation or continuous wave (CW) radiation at 900 MHz with amplitudes of 5.7 and 41 V m(-1) , and outgrowth was studied one week after exposure. The exposure to higher amplitude (41 V m(-1)) GSM radiation resulted in diminished outgrowth of the epicotyl. The exposure to lower amplitude (5.7 V m(-1)) GSM radiation did not influence outgrowth of epicotyl, hypocotyls, or roots. The exposure to higher amplitude CW radiation resulted in reduced outgrowth of the roots whereas lower CW exposure resulted in a reduced outgrowth of the hypocotyl. Soybean seedlings were also exposed for 5 days to an extremely low level of radiation (GSM 900 MHz, 0.56 V m(-1)) and outgrowth was studied 2 days later. Growth of epicotyl and hypocotyl was found to be reduced, whereas the outgrowth of roots was stimulated. Our findings indicate that the observed effects were significantly dependent on field strength as well as amplitude modulation of the applied field. PMID:25644316

  15. An improved procedure to accurately assess the variability of the exposure to electromagnetic radiation emitted by GSM base station antennas

    Long-term human exposure around Global System for Mobile Communications (GSM) base station antennas has not yet been precisely established; this is of interest from human health and epidemiological perspectives. Actual exposure is difficult to assess accurately, mainly because there is a lack of technical information directly from the GSM operators. The in situ measurement standards available at present provide only a worst-case prediction method; the present work goes beyond this and proposes a methodology that, without the need for data from operators, allows a reliable way to express real exposure with a greater accuracy than all other methods proposed to date. The method is based on dual measurements of the signal strengths in the frequency domain and the time domain and takes into consideration the instantaneous traffic in GSM channels. In addition, it allows a channel-individualized exposure assessement, by making possible the separate analysis of the electric field level in the two types of channel of the GSM standard—the traffic channels and the control channels.

  16. A system for environmental monitoring

    The system described in this paper consists of a reader, multi-element dosemeters, and dose algorithm. The reader is a medium capacity non-contact gas heating unit interfaced to an application software package that evaluates and manages generated data. The dosemeter consists of elements that are 240 mg.cm-2 thick and which are symmetrically filtered. The two CaF2:Dy (TLD-200) elements are shielded by 80 mg.cm-2 ABS plastic, 0.25 mm tantalum and 0.05 mm lead. The two LiF:Mg,Ti (TLD-100) are shielded by the 80 mg.cm-2 ABS plastic only. The response of this system was characterised according to the criteria established in the ANSI Standard N545, Section 4, as modified by NRC Regulatory Guide 4.13. The procedures applied to study the energy response, fading, linearity, uniformity, minimum detectability, reproducibility, reponse dependence on angle of incidence are described, reviewed, and the results presented. The study also included self-irradiation, sensitivity to light and moisture, and performance in actual field conditions. The results demonstrate that this dosemeter satisfies all of the N545-1975 performance requirements. The dose calculation algorithm developed for this dosemeter is outlined and the accuracy of its performance in various pure and mixed fields has been determined. The results are presented and discussed. (author)

    2015-12-01

    Full Text Available Industrial Control Systems (ICS are widely deployed in nation’s critical national infrastructures such as utilities, transport, banking and health-care. Whilst Supervisory Control and Data Acquisition (SCADA systems are commonly deployed to monitor real-time data and operations taking place in the ICS they are typically not equipped to monitor the functional behaviour of individual components. In this paper (This paper expands on an earlier position paper presented at the International Symposium for Industrial Control System and SCADA Cyber Security Research 2014, we are presenting a runtime-monitoring technology that provides assurances of the functional behaviour of ICS components and demonstrates how this can be used to provide additional protection of the ICS against cyber attacks similar to the well-known Stuxnet attack.

  19. LHCb: Monitoring the DIRAC Distribution System

    Nandakumar, R; Santinelli, R

    2009-01-01

    DIRAC is the LHCb gateway to any computing grid infrastructure (currently supporting WLCG) and is intended to reliably run large data mining activities. The DIRAC system consists of various services (which wait to be contacted to perform actions) and agents (which carry out periodic activities) to direct jobs as required. An important part of ensuring the reliability of the infrastructure is the monitoring and logging of these DIRAC distributed systems. The monitoring is done collecting information from two sources - one is from pinging the services or by keeping track of the regular heartbeats of the agents, and the other from the analysis of the error messages generated by both agents and services and collected by the logging system. This allows us to ensure that he components are running properly and to collect useful information regarding their operations. The process status monitoring is displayed using the SLS sensor mechanism which also automatically allows one to plot various quantities and also keep ...

  1. Degradation Modelling for Health Monitoring Systems

    Condition-monitoring plays an increasingly important role for technical processes in order to improve reliability, availability, maintenance and lifetime of equipment. With increasing demands for efficiency and product quality, plus progress in the integration of automatic control systems in high-cost mechatronic and critical safety processes, the field of health monitoring is gaining interest. A similar research field is concerned with an estimation of the remaining useful life. A central question in these fields is the modelling of degradation; degradation is a process of a gradual and irreversible accumulation of damage which will finally result in a failure of the system. This paper is based on a current research project and explores various degradation modelling techniques. These results are explained on the basis of an industrial product – a system for the generation of health status information for pump systems. The result of this fuzzy-logic based system is a single number indicating the current health of a pump system

  4. Autonomous remote monitoring system for landslides

    Manetti, Luca; Terribilini, Andrea; Knecht, Alfredo

    2002-07-01

    There is a general tendency in systems for environmental monitoring towards ever more automatic and autonomous operation. Moreover, technologies and instruments are available to reliably interconnect distributed, disparate components. This allows the measurement, logging, data processing and interpretation activities to be carried out by separate units at different locations in near real-time. Building on the results of a previous research and development project at SUPSI, which focused on movement monitoring with GPS, the system has been generalized to accommodate a range of other sensors, thus rendering it even more interesting for geotechnical applications. In particular a laser distance meter and a robotized theodolite have been integrated. First results confirm an expected increase in robustness of the combined measurement network, which is particularly important in unfavorable stand-alone GPS reception conditions. Due to the modular architecture of the system, other sensor types, ranging from simple analog or digital sensors to complex measuring instruments may be supported with minimal effort. Measurements are transmitted via cellular or point-to-point radio links to a control station, which provides for post-processing and system management. The control station may be remotely accessed via an Internet connection. The system takes advantage of a standard and flexible database structure which has been tailored to measurement and monitoring projects using different sensors. The system represents an architecture for remote monitoring tasks requiring a high degree of autonomy, reliability and automation. The solution can be advantageously applied to remote, near real-time measurements of low dynamics movements.

    2016-01-01

    Purpose The current study investigates the feasibility of a platform for a nationwide dose monitoring system for dental radiography. The essential elements for an unerring system are also assessed. Materials and Methods An intraoral radiographic machine with 14 X-ray generators and five sensors, 45 panoramic radiographic machines, and 23 cone-beam computed tomography (CBCT) models used in Korean dental clinics were surveyed to investigate the type of dose report. A main server for storing the dose data from each radiographic machine was prepared. The dose report transfer pathways from the radiographic machine to the main sever were constructed. An effective dose calculation method was created based on the machine specifications and the exposure parameters of three intraoral radiographic machines, five panoramic radiographic machines, and four CBCTs. A viewing system was developed for both dentists and patients to view the calculated effective dose. Each procedure and the main server were integrated into one system. Results The dose data from each type of radiographic machine was successfully transferred to the main server and converted into an effective dose. The effective dose stored in the main server is automatically connected to a viewing program for dentist and patient access. Conclusion A patient radiation dose monitoring system is feasible for dental clinics. Future research in cooperation with clinicians, industry, and radiologists is needed to ensure format convertibility for an efficient dose monitoring system to monitor unexpected radiation dose.

  6. Nanosensor system for monitoring brain activity and drowsiness

    Ramasamy, Mouli; Varadan, Vijay K.; Harbaugh, Robert

    2015-04-01

    Detection of drowsiness in drivers to avoid on-road collisions and accidents is one of the most important applications that can be implemented to avert loss of life and property caused by accidents. A statistical report indicates that drowsy driving is equally harmful as driving under influence of alcohol. This report also indicates that drowsy driving is the third most influencing factor for accidents and 30% of the commercial vehicle accidents are caused because of drowsy driving. With a motivation to avoid accidents caused by drowsy driving, this paper proposes a technique of correlating EEG and EOG signals to detect drowsiness. Feature extracts of EEG and blink variability from EOG is correlated to detect the sleepiness/drowsiness of a driver. Moreover, to implement a more pragmatic approach towards continuous monitoring, a wireless real time monitoring approach has been incorporated using textile based nanosensors. Thereby, acquired bio potential signals are transmitted through GSM communication module to the receiver continuously. In addition to this, all the incorporated electronics are equipped in a flexible headband which can be worn by the driver. With this flexible headband approach, any intrusiveness that may be experienced by other cumbersome hardware is effectively mitigated. With the continuous transmission of data from the head band, the signals are processed on the receiver side to determine the condition of the driver. Early warning of driver's drowsiness will be displayed in the dashboard of the vehicle as well as alertness voice and sound alarm will be sent via the vehicle radio.

  13. Hanger-type laundry monitor system

    Laundry monitor is installed in nuclear power plants or other nuclear facilities in order to efficiently detect radioactive contamination remains on the surfaces of the working clothes which were used in the controlled area and washed afterward. The number of the working clothes which must be measured has been increasing in accordance with the increase of the nuclear facilities. This fact and recent intensified radiation control require automatic, high-speed and high sensitive measurement. Conveyer-type laundry monitor in which the working clothes are inserted by the metal net conveyer has been generally used, and recently new system with an automatic folder has become more popular. But, this type of system has not so big capacity because the clothes are conveyed longitudinally and also requires considerable wide space when installed. Fuji electric Co., Ltd. has been engaging in research and development for an optimum laundry monitor system used in nuclear facilities since the joint investigation with ten electric power companies in Japan in 1982. Consequently hanger-type laundry monitor system using automatic hanger conveyer was developed and 2 systems were delivered to Chubu Electric Power Co., Ltd. in 1986. This system permits to detect radioactive contamination on the working clothes, pick the contaminated clothes out and fold the uncontaminated clothes fully automatically and continuously. Moreover it allows to shorten the measurement time because the clothes are conveyed transversely and save the installation space, so that this will be regarded as considerably complete system in the world. This report describes the outline of the hanger-type laundry monitor system. (author)

  14. National Satellite Forest Monitoring systems for REDD+

    Jonckheere, I. G.

    2012-12-01

    Reducing Emissions from Deforestation and Forest Degradation (REDD) is an effort to create a financial value for the carbon stored in forests, offering incentives for developing countries to reduce emissions from forested lands and invest in low-carbon paths to sustainable development. "REDD+" goes beyond deforestation and forest degradation, and includes the role of conservation, sustainable management of forests and enhancement of forest carbon stocks. In the framework of getting countries ready for REDD+, the UN-REDD Programme assists developing countries to prepare and implement national REDD+ strategies. For the monitoring, reporting and verification, FAO supports the countries to develop national satellite forest monitoring systems that allow for credible measurement, reporting and verification (MRV) of REDD+ activities. These are among the most critical elements for the successful implementation of any REDD+ mechanism. The UN-REDD Programme through a joint effort of FAO and Brazil's National Space Agency, INPE, is supporting countries to develop cost- effective, robust and compatible national monitoring and MRV systems, providing tools, methodologies, training and knowledge sharing that help countries to strengthen their technical and institutional capacity for effective MRV systems. To develop strong nationally-owned forest monitoring systems, technical and institutional capacity building is key. The UN-REDD Programme, through FAO, has taken on intensive training together with INPE, and has provided technical help and assistance for in-country training and implementation for national satellite forest monitoring. The goal of the support to UN-REDD pilot countries in this capacity building effort is the training of technical forest people and IT persons from interested REDD+ countries, and to set- up the national satellite forest monitoring systems. The Brazilian forest monitoring system, TerraAmazon, which is used as a basis for this initiative, allows

  15. Evaluation of a multiport groundwater monitoring system

    In 1988 and 1989, Pacific Northwest Laboratory installed a multiport groundwater monitoring system in two wells on the Hanford Site: one near the 216-B-3 Pond in the center of the Hanford Site and one just north of the 300 Area near the Columbia River. The system was installed to provide the US Department of Energy with needed three-dimensional data on the vertical distribution of contaminants and hydraulic heads on the Hanford Site. This study evaluates the ability of the multiport system to obtain hydrogeologic data at multiple points vertically in a single borehole, and addresses the representativeness of the data. Data collected from the two wells indicate that the multiport system is well suited for groundwater monitoring networks requiring three-dimensional characterization of the hydrogeologic system. A network of these systems could provide valuable information on the hydrogeologic environment. However, the advantages of the multiport system diminish when the system is applied to long-term monitoring networks (30+ years) and to deeper wells (<300 ft). For shallow wells, the multiport system provides data in a cost-effective manner that would not be reasonably obtainable with the conventional methods currently in use at the Hanford Site. 17 refs., 28 figs., 6 tabs

  16. Decision Fusion System for Bolted Joint Monitoring

    Dong Liang

    2015-01-01

    Full Text Available Bolted joint is widely used in mechanical and architectural structures, such as machine tools, industrial robots, transport machines, power plants, aviation stiffened plate, bridges, and steel towers. The bolt loosening induced by flight load and environment factor can cause joint failure leading to a disastrous accident. Hence, structural health monitoring is critical for the bolted joint detection. In order to realize a real-time and convenient monitoring and satisfy the requirement of advanced maintenance of the structure, this paper proposes an intelligent bolted joint failure monitoring approach using a developed decision fusion system integrated with Lamb wave propagation based actuator-sensor monitoring method. Firstly, the basic knowledge of decision fusion and classifier selection techniques is briefly introduced. Then, a developed decision fusion system is presented. Finally, three fusion algorithms, which consist of majority voting, Bayesian belief, and multiagent method, are adopted for comparison in a real-world monitoring experiment for the large aviation aluminum plate. Based on the results shown in the experiment, a big potential in real-time application is presented that the method can accurately and rapidly identify the bolt loosening by analyzing the acquired strain signal using proposed decision fusion system.

  17. Background compensation methodologies for contamination monitoring systems

    Radiation surveillance program in the various nuclear facilities incorporate contamination monitoring as an important component. Contamination monitoring programs constitute monitoring for alpha and beta contamination of the physical entities associated with the working personnel that include his hands, feet, clothing, shoes as well as the general surface areas in the working environment like floors. All these measurements are fraught with the contribution of the ambient gamma background radiation fields. These inhibit a proper and precise estimation of the contamination concentration being monitored. This paper investigates the efficacy of two methodologies that have been incorporated in two of the contamination monitoring systems developed in the Division. In the first system discussed, a high degree of gamma compensation has been achieved for an uniform exposure of the order of 50 nSv/hr to 100 mSv/hr. In the second system discussed, the degree of gamma compensation achieved is equal to those dictated by the statistical nature of the uncertainties associated with the subtraction of background from the source data. These two methods can be very effectively employed depending on the application requirement. A minimum detection level equivalent to 0.37 Bq/cdm2 has been achieved in both these cases

  20. An interactive beam position monitor system simulator

    A system simulator has been implemented to aid the development of the RHIC position monitor system. Based on the LabVIEW software package by National Instruments, this simulator allows engineers and technicians to interactively explore the parameter space of a system during the design phase. Adjustable parameters are divided into three categories: beam, pickup, and electronics. The simulator uses these parameters in simple formulas to produce results in both time-domain and frequencydomain. During the prototyping phase, these simulated results can be compared to test data acquired with the same software package. The RHIC position monitor system is presented as an example, but the software is applicable to several other systems as well

  1. Monitoring the atlas distributed data management system

    The ATLAS Distributed Data Management (DDM) system is evolving to provide a production-quality service for data distribution and data management support for production and users' analysis. Monitoring the different components in the system has emerged as one of the key issues to achieve this goal. Its distributed nature over different grid infrastructures (EGEE, OSG and NDGF) with infrastructure-specific data management components makes the task particularly challenging. Providing simple views over the status of the DDM components and data to users and site administrators is essential to effectively operate the system under realistic conditions. In this paper we present the design of the DDM monitor system, the information flow, data aggregation. We discuss the available usage, the interactive functionality for end-users and the alarm system

    2011-06-01

    Full Text Available Air pollution has significant influence on the concentration of constituents in the atmosphere leading to effects like global warming and acid rains. To avoid such adverse imbalances in the nature, an air pollution monitoring system is utmost important. This paper attempts to develop an effective solution for pollution monitoring using wireless sensor networks (WSN on a real time basis namely real time wireless air pollution monitoring system. Commercially available discrete gas sensors for sensing concentration of gases like CO2, NO2, CO and O2 are calibrated using appropriate calibration technologies. These pre-calibrated gas sensors are then integrated with the wireless sensor motes for field deployment at the campus and the Hyderabad city using multi hop data aggregation algorithm. A light weight middleware and a web interface to view the live pollution data in the form of numbers and charts from the test beds was developed and made available from anywhere on the internet. Other parameters like temperature and humidity were also sensed along with gas concentrations to enable data analysis through data fusion techniques. Experimentation carried out using the developed wireless air pollution monitoring system under different physical conditions show that the system collects reliable source of real time fine-grain pollution data.

  13. Mobile Monitoring System for Nuclear Contamination Analysis

    In case of a nuclear accident, it is essential to have extensive knowledge concerning the nature of the radioactive plume expansion, for further analysis. For this purpose a mobile monitoring system may provide important data about the plume characteristics. An advanced Mobile Monitoring System is under development at the Nuclear Research Center-Negev. The system is composed of a network of mobile stations, typically installed onboard vehicles, which transmit radiation measurements along with position information to a central station. The mobile network's communications infrastructure is based on Motorola Mobile Logic Unit devices, which are state-of-the-art reliable modems with an integrated Global Positioning System module. The radiation measurements received by the central station are transferred to a risk assessment program, which evaluates the expected hazards to the populated areas located in the estimated plume's expansion direction

  14. Energy Consumption Monitoring System for Large Complexes

    Jorge, André; Guerreiro, João; Pereira, Pedro; Martins, João; Gomes, Luís

    This paper describes the development of an open source system for monitoring and data acquisition of several energy analyzers. The developed system is based on a computer with Internet/Intranet connection by means of RS485 using Modbus RTU as communication protocol. The monitoring/metering system was developed for large building complexes and was validated in the Faculdade de Ciências e Tecnologia University campus. The system considers two distinct applications. The first one allows the user to verify, in real time, the energy consumption of any department in the complex, produce load diagrams, tables and print, email or save all available data. The second application keeps records of active/reactive energy consumption in order to verify the existence of some anomalous situation, and also monthly charge energy consumption to each corresponding department.

  1. Replaceable Sensor System for Bioreactor Monitoring

    Mayo, Mike; Savoy, Steve; Bruno, John

    2006-01-01

    A sensor system was proposed that would monitor spaceflight bioreactor parameters. Not only will this technology be invaluable in the space program for which it was developed, it will find applications in medical science and industrial laboratories as well. Using frequency-domain-based fluorescence lifetime technology, the sensor system will be able to detect changes in fluorescence lifetime quenching that results from displacement of fluorophorelabeled receptors bound to target ligands. This device will be used to monitor and regulate bioreactor parameters including glucose, pH, oxygen pressure (pO2), and carbon dioxide pressure (pCO2). Moreover, these biosensor fluorophore receptor-quenching complexes can be designed to further detect and monitor for potential biohazards, bioproducts, or bioimpurities. Biosensors used to detect biological fluid constituents have already been developed that employ a number of strategies, including invasive microelectrodes (e.g., dark electrodes), optical techniques including fluorescence, and membrane permeable systems based on osmotic pressure. Yet the longevity of any of these sensors does not meet the demands of extended use in spacecraft habitat or bioreactor monitoring. It was therefore necessary to develop a sensor platform that could determine not only fluid variables such as glucose concentration, pO2, pCO2, and pH but can also regulate these fluid variables with controlled feedback loop.

  2. Ubiquitous Health Monitoring Systems: Addressing Security Concerns

    Mahmoud Elkhodr

    2011-01-01

    Full Text Available Problem statement: It is important to secure the transmission of patient’s EHR in remote health monitoring systems. Security is among the main issues that need to be realized for the adaption of this monitoring technology. The face of healthcare is changing as ubiquitous computing technologies are being incorporated into the existing infrastructure. We specify the requirements, needed security mechanism, outstanding issues and the future challenges as well as the open problems that need to be achieved. Approach: Although there were benefits to technology, approaches that offer reliable privacy and security features must be presented to users in order to make these systems socially accepted. Results: We investigated the privacy and security implications generated from the deployment of remote health monitoring technology. To achieve these security requirements, building on the strengths of Transport Layer Security (TLS protocol, a trust negotiation approach was proposed. The application of this approach results in significant improvements in overcoming security related concerns compared to the traditional identity-based only access control techniques. Conclusion: We believe these considerations will eventually contribute toward an efficient and practical deployment of remote monitoring systems.

  3. A matrix-form GSM-CFD solver for incompressible fluids and its application to hemodynamics

    Yao, Jianyao; Liu, G. R.

    2014-10-01

    A GSM-CFD solver for incompressible flows is developed based on the gradient smoothing method (GSM). A matrix-form algorithm and corresponding data structure for GSM are devised to efficiently approximate the spatial gradients of field variables using the gradient smoothing operation. The calculated gradient values on various test fields show that the proposed GSM is capable of exactly reproducing linear field and of second order accuracy on all kinds of meshes. It is found that the GSM is much more robust to mesh deformation and therefore more suitable for problems with complicated geometries. Integrated with the artificial compressibility approach, the GSM is extended to solve the incompressible flows. As an example, the flow simulation of carotid bifurcation is carried out to show the effectiveness of the proposed GSM-CFD solver. The blood is modeled as incompressible Newtonian fluid and the vessel is treated as rigid wall in this paper.

  4. 基于随机Petri网的GSM-R越区切换成功率分析%Analysis of GSM-R Handover Switching Success Rate Based on Stochastic Petri Net

    许德超; 米根锁; 张小花

    2015-01-01

    CTCS ( China Train Control System ) level-3 uses GSM-R networks to conduct continuous two-way security information transmission between train and ground. However, GSM-R system adopts hard-switching technology, which will produce a short time communication interrupt and affect train control data transmission. In order to ensure the reliability of security data transmission, shorter time and higher success rate of switching is urgently required. Therefore, this paper establishes a stochastic Petri net model of GSM-R system switching and analyzes the factors that impact the success rate of crossover switching. The relationships between and among the train speed, crossover switching interruption time, and train tracking interval and crossover switching success rate are obtained with MATLAB simulation. Finally, the paper illustrates whether the crossover switching success rate meets the system requirements of CTCS-3 when the train runs at the speeds of 350km/h and 430km/h.%CTCS-3级列车运行控制系统利用GSM-R网络进行车地间连续、双向的安全信息传输。而GSM-R系统采用硬切换技术,切换时必然会产生短暂的通信中断,这就会影响列车控制类数据传输业务。为保证安全数据传输的可靠性,迫切要求更短的切换时间和更高的切换成功率。对此,建立GSM-R系统越区切换的随机Petri网模型,分析影响越区切换成功率的因素,并利用MATLAB仿真得到列车运行速度、越区切换中断时间以及列车追踪间隔与越区切换成功率的关系;最后说明列车在350 km/h 和430 km/h 速度下运行时,越区切换成功率是否满足CTCS-3级系统需求标准要求。

  9. A Resilient Condition Assessment Monitoring System

    Humberto Garcia; Wen-Chiao Lin; Semyon M. Meerkov

    2012-08-01

    An architecture and supporting methods are presented for the implementation of a resilient condition assessment monitoring system that can adaptively accommodate both cyber and physical anomalies to a monitored system under observation. In particular, the architecture includes three layers: information, assessment, and sensor selection. The information layer estimates probability distributions of process variables based on sensor measurements and assessments of the quality of sensor data. Based on these estimates, the assessment layer then employs probabilistic reasoning methods to assess the plant health. The sensor selection layer selects sensors so that assessments of the plant condition can be made within desired time periods. Resilient features of the developed system are then illustrated by simulations of a simplified power plant model, where a large portion of the sensors are under attack.

  10. A design methodology for unattended monitoring systems

    The authors presented a high-level methodology for the design of unattended monitoring systems, focusing on a system to detect diversion of nuclear materials from a storage facility. The methodology is composed of seven, interrelated analyses: Facility Analysis, Vulnerability Analysis, Threat Assessment, Scenario Assessment, Design Analysis, Conceptual Design, and Performance Assessment. The design of the monitoring system is iteratively improved until it meets a set of pre-established performance criteria. The methodology presented here is based on other, well-established system analysis methodologies and hence they believe it can be adapted to other verification or compliance applications. In order to make this approach more generic, however, there needs to be more work on techniques for establishing evaluation criteria and associated performance metrics. They found that defining general-purpose evaluation criteria for verifying compliance with international agreements was a significant undertaking in itself. They finally focused on diversion of nuclear material in order to simplify the problem so that they could work out an overall approach for the design methodology. However, general guidelines for the development of evaluation criteria are critical for a general-purpose methodology. A poor choice in evaluation criteria could result in a monitoring system design that solves the wrong problem

    Traditional feedforward structures suffer from performance constraints caused by the complex adder before quantizer. This paper presents an improved 4th-order 1-bit sigma-delta modulator which has a simple adder and delayed input feedforward to relax timing constraints and implement low-distortion. The modulator was fabricated in a 0.35 μm CMOS process, and it achieved 92.8 dB SNDR and 101 dB DR with a signal bandwidth of 100 kHz dissipating 8.6 mW power from a 3.3-V supply. The performance satisfies the requirements of a GSM system. (semiconductor integrated circuits)

  15. Knowledge based systems for condition monitoring

    McDonald, J.R.; Burt, G.M.; Moyes, A.

    1997-12-31

    A key issue in the operation of power system plant is deriving maximum financial benefit while staying within technical, contractual and regulatory constraints. Moreover, the capital investment required for much power system plant necessitates high levels of plant availability to make a reasonable rate-of-return. Thus, the minimisation of operational costs resulting from unplanned plant outages, unnecessary maintenance and under-utilisation of plant capabilities has become a core objective of power system plant operation. Rationalisation of power system control functions has resulted in the use of centralised control rooms from which large and complex power systems are operated. Extensive measurement, monitoring and control systems have been developed which provide operators with data from which power system plant behaviour can be evaluated. However, in the event of a serious operational incident, significant amounts of data are generated. Under such circumstances it has been found that operators are inhibited in assessing the situation, and hence the effectiveness of the subsequent operational response can be reduced. The role of knowledge based systems (KBSs) in condition monitoring is to support operational decision making through the provision of timely and focused information. (Author)

    In this paper we have briefly described our practical experiences with the most complex Radiation Monitoring System we have designed. This system consists of number of stations; those data are collected in the main crisis center of the whole system. The main center integrates RMS Central Database, the IMS Model Suite workstation and the Graphics workstation. The radiations probes of the RP series are the base for stationary , portable sets and for sets measuring underwater radiation. The radiation and meteorological data, which are necessary for reasonable interpretation of radiation data, are archived in RMS Central database. The Lagrangian trajectory model from the IMS Model Suite serves for radiation dispersion modeling. (authors)

  17. Delta count-rate monitoring system

    A need for a more effective way to rapidly search for gamma-ray contamination over large areas led to the design and construction of a very sensitive gamma detection system. The delta count-rate monitoring system was installed in a four-wheel-drive van instrumented for environmental surveillance and accident response. The system consists of four main sections: (1) two scintillation detectors, (2) high-voltage power supply amplifier and single-channel analyzer, (3) delta count-rate monitor, and (4) count-rate meter and recorder. The van's 6.5-kW generator powers the standard nuclear instrument modular design system. The two detectors are mounted in the rear corners of the van and can be run singly or jointly. A solid-state bar-graph count-rate meter mounted on the dashboard can be read easily by both the driver and passenger. A solid-state strip chart recorder shows trends and provides a permanent record of the data. An audible alarm is sounded at the delta monitor and at the dashboard count-rate meter if a detected radiation level exceeds the set background level by a predetermined amount

  18. Integrated monitoring and surveillance system demonstration project

    We present a summary of efforts associated with the installation of an integrated system for the surveillance and monitoring of stabilized plutonium metals and oxides in long-term storage. The product of this effort will include a Pu storage requirements document, baseline integrated monitoring and surveillance system (IMSS) prototype and test bed that will be installed in the Fuel Manufacturing Facility (FMF) nuclear material vault at Argonne National Laboratory - West (ANL-W), and a Pu tracking database including data analysis capabilities. The prototype will be based on a minimal set of vault and package monitoring requirements as derived from applicable DOE documentation and guidelines, detailed in the requirements document, including DOE-STD-3013-96. The use of standardized requirements will aid individual sites in the selection of sensors that best suit their needs while the prototype IMSS, located at ANL-W, will be used as a test bed to compare and contrast sensor performance against a baseline integrated system (the IMSS), demonstrate system capabilities, evaluate potential technology gaps, and test new hardware and software designs using various storage configurations. With efforts currently underway to repackage and store a substantial quantity of plutonium and plutonium-bearing material within the DOE complex, this is an opportune time to undertake such a project. 4 refs

    In this paper we present the unique and innovative 'Integriti' pipeline and flow line integrity monitoring system developed by Schlumberger in collaboration with BP. The system uses optical fiber distributed sensors to provide simultaneous distributed measurements of temperature, strain and vibration for the detection, monitoring, and location of events including: Third Party Interference (TPI), including multiple simultaneous disturbances; geo-hazards and landslides; gas and oil leaks; permafrost protection. The Integriti technology also provides a unique means for tracking the progress of cleaning and instrumented pigs using existing optical telecom and data communications cables buried close to pipelines. The Integriti solution provides a unique and proactive approach to pipeline integrity management. It performs analysis of a combination of measurands to provide the pipeline operator with an event recognition and location capability, in effect providing a hazard warning system, and offering the operator the potential to take early action to prevent loss. Through the use of remote, optically powered amplification, an unprecedented detection range of 100 km is possible without the need for any electronics and therefore remote power in the field. A system can thus monitor 200 km of pipeline when configured to monitor 100 km upstream and downstream from a single location. As well as detecting conditions and events leading to leaks, this fully integrated system provides a means of detecting and locating small leaks in gas pipelines below the threshold of present online leak detection systems based on monitoring flow parameters. Other significant benefits include: potential reductions in construction costs; enhancement of the operator's existing integrity management program; potential reductions in surveillance costs and HSE risks. In addition to onshore pipeline systems this combination of functionality and range is available for practicable

The crime rate in every part of the society these days has become a threatening issue such that vehicles are now used for committing criminal activities more than before. The issue of vehicle theft has increased tremendously, mostly at gunpoint or car parks. In view of these, there is a need for adequate records of stolen, identified and recovered vehicles which are not readily available in our society and as such very important. The development of a vehicle theft alert and location identification system becomes more necessary for vehicle owners to ensure theft prevention and a speedy identification towards recovery efforts in situations where a vehicle is missing, stolen or driven by an unauthorized person. The theft alert function makes use of a GSM application developed and installed in a mobile phone device which is embedded in the vehicle to communicate with the vehicle owner’s mobile phone. The communication is established via SMS (i.e. between the installed mobile phone device and that of the vehicle owner. The communications established include; (i. Sending an SMS alert from installed mobile phone device to vehicle owner mobile phone when the car ignition is put on. (ii. Sending an SMS from the vehicle owner’s mobile phone to start and stop the installed mobile phone device application. The location identification function makes use of a web application developed to; (i. Determine the real time location of a vehicle by means of tracking using GPS. (ii. Broadcast missing or stolen vehicle information to social media and security agency. The implementation of the installed mobile phone device application was done using JAVA because of its capabilities in programming mobile applications while PHP and MySQL was used for the web application functions. Integration testing of the system was carried out using

  1. FOSREM - Fibre-Optic System for Rotational Events&Phenomena Monitoring

    Jaroszewicz, Leszek; Krajewski, Zbigniew; Kurzych, Anna; Kowalski, Jerzy; Teisseyre, Krzysztof

    2016-04-01

    We present the construction and tests of fiber-optic rotational seismometer named FOSREM (Fibre-Optic System for Rotational Events&Phenomena Monitoring). This presented device is designed for detection and monitoring the one-axis rotational motions, brought about to ground or human-made structures both by seismic events and the creep processes. The presented system works by measuring Sagnac effect and generally consists of two basic elements: optical sensor and electronic part. The optical sensor is based on so-called the minimum configuration of FOG (Fibre-Optic Gyroscope) where the Sagnac effect produces a phase shift between two counter-propagating light beams proportional to the measured rotation speed. The main advantage of the sensor of this type is its complete insensitivity to linear motions and a direct measurement of rotational speed. It may work even when tilted, moreover, used in continuous mode it may record the tilt. The electronic system, involving specific electronic solutions, calculates and records rotational events data by realizing synchronous in a digital form by using 32 bit DSP (Digital Signal Processing). Storage data and system control are realised over the internet by using connection between FOSREM and GSM/GPS. The most significant attribute of our system is possibility to measure rotation in wide range both amplitude up to 10 rad/s and frequency up to 328.12 Hz. Application of the wideband, low coherence and high power superluminescent diode with long fibre loop and suitable low losses optical elements assures the theoretical sensitivity of the system equal to 2·10-8 rad/s/Sqrt(Hz). Moreover, the FOSREM is fully remote controlled as well as is suited for continuous, autonomous work in very long period of time (weeks, months, even years), so it is useful for systematic seismological investigation at any place. Possible applications of this system include seismic monitoring in observatories, buildings, mines and even on glaciers and in

    Chomont, Arthur Rene; The ATLAS collaboration

    2016-01-01

    The ATLAS Tile Calorimeter (TileCal) is the central section of the hadronic calorimeter of the ATLAS experiment and provides important information for reconstruction of hadrons, jets, hadronic decays of tau leptons and missing transverse energy. This sampling calorimeter uses steel plates as absorber and scintillating tiles as active medium. The light produced by the passage of charged particles is transmitted by wavelength shifting fibres to photomultiplier tubes (PMTs), located on the outside of the calorimeter. The readout is segmented into about 5000 cells (longitudinally and transversally), each of them being read out by two PMTs in parallel. To calibrate and monitor the stability and performance of each part of the readout chain during the data taking, a set of calibration systems is used. The TileCal calibration system comprises Cesium radioactive sources, laser and charge injection elements and it allows to monitor and equalize the calorimeter response at each stage of the signal production, from scin...

    2010-11-01

    The designed and simulated system will be used in the tanning industry, for Volatile Organic Compound (VOC) measurements. In this industry, about 90% of the solvent contained in the emulsions evaporates during its application, giving rise to VOC, which are at the same time hazardous atmospheric pollutants and one of the sources of ground level photochemical ozone formation. It results that a monitoring system is necessary in a leather finishing process, in order to detect hazardous VOC concentration and conducting process in order of VOC concentration diminishing. The paper presents the design of a VOC monitoring system, which includes sensors for VOCs and temperature, the conditioning circuitry for these sensors, the suction system of the gas in the hood, the data acquisition and the computing system and graphic interface. The used sensor in the detection system is a semiconductor sensor, produced by Figaro Engineering Inc., characterized by a short response time, high sensitivity at almost all VOC substances. The design of the conditioning circuitry and data acquisition is done in order to compensate the sensor response variation with temperature and to maintain the low response time of the sensor. The temperature compensation is obtained by using a thermistor circuitry, and the compensation is done within the software design. A Mitsubishi PLC is used to receive the output signals of the circuits including the sensor and of the thermistor, respectively. The acquisition and computing system is done using Mitsubishi ALPHA 2 controller and a graphical terminal, GOT 1000.

    Full Text Available Designing and implementing commercial as well as industrialized systems based on Wireless. Robust communication has always been a important field of interest among many researchers and developers. Many special protection systems are available based on volume of power distributed and often the load changes without calculation required an advanced and special communication based systems to control the electrical parameters of the generation. Most of the existing systems are reliable on various applications but not perfect for electrical applications. Electrical environment will have lots of disturbance in nature, Due to natural disasters like storms, cyclones or heavy rains transmission and distribution lines may lead to damage. The electrical wire may cut and fall on ground, this leads to very harmful for human beings and may become fatal. So, a inflexible, dependable and robust communications like GSM technology instead of many communication techniques used previous. This technology saves human life from this electrical danger by providing the fault detection and automatically stops the electricity to the damaged line and also conveys the message to the electricity board to clear the fault. A powerful GSM networking is designed to send data from a network to other network. Any change in parameters of transmission is sensed to protect the entire transmission and distribution.

  11. Cell death induced by GSM 900-MHz and DCS 1800-MHz mobile telephony radiation

    In the present study, the TUNEL (Terminal deoxynucleotide transferase dUTP Nick End Labeling) assay '' a well known technique widely used for detecting fragmented DNA in various types of cells'' was used to detect cell death (DNA fragmentation) in a biological model, the early and mid stages of oogenesis of the insect Drosophila melanogaster. The flies were exposed in vivo to either GSM 900-MHz (Global System for Mobile telecommunications) or DCS 1800-MHz (Digital Cellular System) radiation from a common digital mobile phone, for few minutes per day during the first 6 days of their adult life. The exposure conditions were similar to those to which a mobile phone user is exposed, and were determined according to previous studies of ours [D.J. Panagopoulos, A. Karabarbounis, L.H. Margaritis, Effect of GSM 900-MHz mobile phone radiation on the reproductive capacity of D. melanogaster, Electromagn. Biol. Med. 23 (1) (2004) 29''43; D.J. Panagopoulos, N. Messini, A.

  13. The COMPASS control and engineering monitoring system

    The high degree of flexibility of the COMPASS experiment demands a control system readily adaptable to the various modes and operating conditions of the machine. The COMPASS Machine Control System therefore relies on programmable devices with the bulk of the control sequencing resident in the system software. The central control facility provides the main operator interface to the system using touch-sensitive colour monitors to set up the configuration and shot data base. A central computer transmits the processed information to five subsystem control points each of which uses a Programmable Controller to communicate with central control and enable local subsystem operation using a local control panel. Separate from the MCS, though interacting with it, are dedicated systems for fact sequence timing, personnel safety and fast engineering data monitoring. The latter system will collect and process transient signals too fast for the MCS to handle. The data will be archived along with the engineering set-up parameters and physics data and will be available for review at the central control desk

    2005-05-01

    In an urban highway network system such as Tokyo Metropolitan Expressway, to detect conditions of road pavement and expansion joints is a very important issue. Although accurate surface condition can be captured by using a road profiler system, the operating cost is expensive and development of a simpler and more inexpensive system is really needed to reduce monitoring cost. "Vehicle Intelligent Monitoring System (VIMS)" developed for this purpose is described in this paper. An accelerometer and GPS are installed to an ordinary road patrol car. GPS together with a PC computer are used to measure the road surface condition and to identify the location of the vehicle, respectively. Dynamic response of the vehicle is used as a measure of the road pavements surface condition as well as the expansion joints. A prototype of VIMS is installed to a motor car and measurement is made at the actual roads. Accuracy of measuring result and effectiveness of this system are demonstrated; the outline of the system and some of the measurement results are reported herein.

  15. Reactor coolant pump monitoring and diagnostic system

    In order to reliably and safely operate a nuclear power plant, it is necessary to continuously monitor the performance of numerous subsystems to confirm that the plant state is within its prescribed limits. An important function of a properly designed monitoring system is the detection of incipient faults in all subsystems (with the avoidance of false alarms) coupled with an information system that provides the operators with fault diagnosis, prognosis of fault progression and recommended (either automatic or prescriptive) corrective action. In this paper, such a system is described that has been applied to reactor coolant pumps. This system includes a sensitive pattern-recognition technique based upon the sequential probability ratio test (SPRT) that detects incipient faults from validated signals, an expert system embodying knowledge bases on pump and sensor performance, extensive hypertext files containing operating and emergency procedures as well as pump and sensor information and a graphical interface providing the operator with easily perceived information on the location and character of the fault as well as recommended corrective action. This system is in the prototype stage and is currently being validated utilizing data from a liquid-metal cooled fast reactor (EBR-II). 3 refs., 4 figs

  16. Optimal logic structure of safety monitoring systems

    This paper introduces an optimal logic structure of a safety monitoring system to minimize the expected total loss incurred upon fail-dangerous (FD) failures or fail-safe (FS) failures. This paper is divided into three parts. The first part considers the safety monitoring system composed of several channels. Each channel has identical sensors to monitor a plant state variable, e.g., temperature of pressure. When a state variable becomes abnormal, the corresponding channel issues a channel alarm for protective action. The problem is to design an optimal, coherent structure for each channel when the channels are logically connected according to an accident occurence mechanism. For the one-channel system, the optimal channel structure is proven to be k*-out-of-n: G, and k* can be calculated analytically. For the multi-channel system, the optimal channel structure is a k-out-of-n: G, and the problem is formulated as a non-linear integer programming (NLIP) which can be solved by the extended Lawler and Bell's method. The second part generalizes the first part to cover more general optimization of the logic structure without assuming ad-hoc channel connections. The optimal, Boolean structure can be determined by a switching function. The monotone property enables one to employ a systematic search method for a simple expression of the optimal structure. A probabilistic logic structure is discussed and proven to be reduced to a deterministic one. The last part disccusses an optimal shut-down logic for the overall protective system, which is composed of the driving, judging, and sensing sections. Each section may fail in two ways: FD or FS. The optimal shut-down logic, as before, is determined by a switching function. For the system with reliable judging and driving sections, the optimal shut-down logic can be determined based on the reliability information of the sensing section. (author)

  19. Monitoring Digital Closed-Loop Feedback Systems

    Katz, Richard; Kleyner, Igor

    2011-01-01

    A technique of monitoring digital closed-loop feedback systems has been conceived. The basic idea is to obtain information on the performances of closed-loop feedback circuits in such systems to aid in the determination of the functionality and integrity of the circuits and of performance margins. The need for this technique arises as follows: Some modern digital systems include feedback circuits that enable other circuits to perform with precision and are tolerant of changes in environment and the device s parameters. For example, in a precision timing circuit, it is desirable to make the circuit insensitive to variability as a result of the manufacture of circuit components and to the effects of temperature, voltage, radiation, and aging. However, such a design can also result in masking the indications of damaged and/or deteriorating components. The present technique incorporates test circuitry and associated engineering-telemetry circuitry into an embedded system to monitor the closed-loop feedback circuits, using spare gates that are often available in field programmable gate arrays (FPGAs). This technique enables a test engineer to determine the amount of performance margin in the system, detect out of family circuit performance, and determine one or more trend(s) in the performance of the system. In one system to which the technique has been applied, an ultra-stable oscillator is used as a reference for internal adjustment of 12 time-to-digital converters (TDCs). The feedback circuit produces a pulse-width-modulated signal that is fed as a control input into an amplifier, which controls the circuit s operating voltage. If the circuit s gates are determined to be operating too slowly or rapidly when their timing is compared with that of the reference signal, then the pulse width increases or decreases, respectively, thereby commanding the amplifier to increase or reduce, respectively, its output level, and "adjust" the speed of the circuits. The nominal

    The Frascati Tokamak Upgrade (FTU) continuous (slow) data acquisition system has been redesigned to allow easy monitoring of the status of the plant. In the new system 'Opto22(TM)' modules, which use Ethernet as fieldbus, substitute the old 'programmable logic controller (PLC)' devices allowing easy access to and display of many continuous measurements. Data collected by 'Opto22' modules are stored in a 'MySQL' database via a driver written in C++ language. A 'CORBA' server, running on the same machine hosting the 'MySQL' server, allows the database access from any remote client regardless of the local platform. A remarkable aspect looks out for the use of totally free software packages. This new architecture overcomes the limitations of the previous monitoring system:*an interface based on internet browser allows to easily configure Opto22 modules and MySQL database; a graphical interface, developed in Java, allows data management and visualization; the above operations are completely platform independent. In addition the CORBA server introduces the advantages of:hardware independence, thus allowing maximum flexibility in the choice of platforms and system components; both network and programming languages being completely transparent. This paper will present the new system architecture, last results and future developments.

  5. Expert systems for protective monitoring of facilities

    In complex plants, the possibility of serious operator error always exists to some extent, but, this can be especially true during an experiment or some other unusual exercise. Possible contributing factors to operational error include personnel fatigue, misunderstanding in communication, mistakes in executing orders, uncertainty about the delegated authority, pressure to meet a demanding schedule, and a lack of understanding of the possible consequences of deliberate violations of the facility's established operating procedures. Authoritative reports indicate that most of these factors were involved in the disastrous Russian Chernobyl-4 nuclear reactor accident in April 1986, which, ironically, occurred when a safety experiment was being conducted. Given the computer hardware and software now available for implementing expert systems together with integrated signal monitoring and communications, plant protection could be enhanced by an expert system with extended features to monitor the plant. The system could require information from the operators on a rigidly enforced schedule and automatically log in and report on a scheduled time basis to authorities at a central remote site during periods of safe operation. Additionally, the system could warn an operator or automatically shut down the plant in case of dangerous conditions, while simultaneously notifying independent, responsible, off-site personnel of the action taken. This approach would provide protection beyond that provided by typical facility scram circuits. This paper presents such an approach to implementing an expert system for plant protection, together with specific hardware and software configurations. The Chernobyl accident is used as the basis of discussion

  6. PWR core monitoring system and benchmarking

    The PWR Power Shape Monitoring System (PSMS) provides site engineers with new capabilities for monitoring and predicting core power distributions. These capabilities can lead to increased plant output as a result of greater operating margins, better load maneuvering, earlier detection of anomalies, and improved fuel reliability. The heart of the PSMS consists of nodal code (NODEP-2/THERM-P) that computes the 3-D core power distribution. This code is coupled to a simplified nodal version of the COBRA-IIIC/MIT-2 thermal-hydraulic model to determine the DNBR. These calculations can be completed in about 30 seconds on a PRIME-750 mini computer. Activation of the calculations and review of the results is through user-friendly interactive software that can be tailored to the requirements and capabilities of the different categories of users through table-driven menus. The PSMS provides unique advances over core power monitoring systems based purely on measurements. The PSMS approach permits the three-dimensional core simulation model to be routinely corrected with in-core/ex-core measurements while simultaneously identifying consistent instrument errors

    Hao, Zengchao; AghaKouchak, Amir; Nakhjiri, Navid; Farahmand, Alireza

    2014-01-01

    Drought is by far the most costly natural disaster that can lead to widespread impacts, including water and food crises. Here we present data sets available from the Global Integrated Drought Monitoring and Prediction System (GIDMaPS), which provides drought information based on multiple drought indicators. The system provides meteorological and agricultural drought information based on multiple satellite-, and model-based precipitation and soil moisture data sets. GIDMaPS includes a near real-time monitoring component and a seasonal probabilistic prediction module. The data sets include historical drought severity data from the monitoring component, and probabilistic seasonal forecasts from the prediction module. The probabilistic forecasts provide essential information for early warning, taking preventive measures, and planning mitigation strategies. GIDMaPS data sets are a significant extension to current capabilities and data sets for global drought assessment and early warning. The presented data sets would be instrumental in reducing drought impacts especially in developing countries. Our results indicate that GIDMaPS data sets reliably captured several major droughts from across the globe. PMID:25977759

  9. Dielectric Track Detector fuel motion monitor system

    The fuel motion monitor system described is one of the systems being developed for use in the upgraded Sandia ACPR. Like the hodoscope, this system will image fast neutrons from the test fuel element--but there the similarity to the hodoscope ends, because this system will use Dielectric Track Detectors (DTD's) for both neutron detection and recording. Kimfoil is a commercial polycarbonate film that is used as a capacitor dielectric. It is just one example of a Dielectric Track Detector. When a DTD is struck by an energetic and heavy ion, the ion produces damage along its path. If the dielectric is then etched, the damaged track enlarges to form a crater. These craters are then easily visible with an optical microscope. These dielectrics have several properties that make them ideal for use in a reactor environment. First of all, they are completely insensitive to any of the background radiations to which they can be exposed in that environment

    2014-01-01

    Full Text Available Handover is the mechanism that transfers information from one terminal to another as a user moves through the coverage area of a cellular system. Here the Network selection is the handover decision process between various network environments. This handover decision will be either mobile or network initiated. In 2G GSM handover decision method especially concentrates on Received frequency signals (RFS. Upcoming technologies (3G/4G the number of available networks increase the selection process should evaluate additional factors such as cost, network services, network terminology, system conditions, user and operators performances and needed energy to work in an exceedingly network. In Future networks (IEEE or 4G standards offer facilities such as network routes, handover routing messages, network and client reports, message exchange with handover triggers and handover negotiation. In this study we have a tendency to discuss the utilization of a cost function to perform associate a network selection exploitation information provided by these standards, such as network coverage or network properties. The efficient function provides flexibility to balance the various factors within the network selection, and our research is focused on rising each seamlessness and energy efficiency of the devices in handovers. We have a tendency to evaluate our approach supported usage scenarios over 2G, 3G and 4G GSM networks. Our results show the optimal networks and handovers were generate appropriate times to increase overall network connectivity as compared to traditional network schemes, at the same time optimizing energy consumption of network devices.

  13. Fence line noble gas monitoring system

    A new system has been developed for monitoring noble gas emissions at the fence line around the Pickering NPP in Canada. The system differs from the traditional method of assessing the dose to the critical group based on meteorological models. Instead, the new system monitors the dose directly at the fence line, which in fact has reduced the reported doses by 1 to 2 orders of magnitude. Typical annual Minimum Detectable Levels (MDLs)4 in Air Kerma are 1.8 nGy (135Xe), 4.2 nGy (135Xe), and 11.0 nGy (41Ar). The complete system comprises 7 self-contained Na(Tl) detector units located around the Pickering fence line. System design makes each detector assembly a stand-alone unit with internal data scanning, Stabilization and data storage capability. Each detector has been calibrated for Air Kerma, Ambient Dose Equivalent, Effective Dose (adults), and Effective Dose (Juvenile)5. The detector systems are polled every 24 hrs. (user selected from real-time to every 7 days as required) by one or more central computers. The central computers collect spectral data from each detector unit and store all the data in a SQL database. The data is analyzed and preliminary noble gas concentration calculated. Every month the complete data set for the month is reevaluated based on actual wind information using the new computed calibration factors, to achieve maximum data accuracy. The system creates automatic monthly reports with tables of emissions and MDLs. Included in the reports are also graphs of the emissions during the month. (author)

    Moure, David; Torres, Pedro A.; Meletlidis, Stavros; Lopez, Carmen; José Blanco, María

    2014-05-01

    A low cost and low power consumption multiparametric system designed for volcano monitoring is presented. Once tested with various sensors, at present it is installed in two locations in Tenerife, Canary Islands, acquiring and transmitting data in real time. The system is based on a commercial board (Raspberry Pi®, RPi®) that uses an embedded ARMTM processor with a Debian (Wheezy-Raspbian) Linux Operating System. This configuration permits different standard communication systems between devices as USB and ETHERNET, and also communication with integrated circuits is possible. The whole system includes this platform and self-developed hardware and software. Analog signals are acquired at an expansion board with an ADC converter with three 16 bits channels. This board, which is powered directly from the RPi®, provides timing to the sampling data using a Real Time Clock (RTC). Two serial protocols (I2C and SPI) are responsible for communications. Due to the influence of atmospheric phenomena on the volcano monitoring data, the system is complemented by a self-developed meteorological station based on ArduinoCC and low cost commercial sensors (atmospheric pressure, humidity and rainfall). It is powered with the RPi® and it uses a serial protocol for communications. Self-developed software run under Linux OS and handles configuration, signal acquisition, data storage (USB storage or SD card) and data transmission (FTP, web server). Remote configuration, data plotting and downloading is available through a web interface tool. Nowadays, the system is used for gravimetric and oceanic tides data acquisition in Tenerife and soon it will be applied for clinometric data.

    The clinical electroencephalogram (EEG) monitoring systems based on personal computer system can not meet the requirements of portability and home usage. The epilepsy patients have to be monitored in hospital for an extended period of time, which imposes a heavy burden on hospitals. In the present study, we designed a portable 16-lead networked monitoring system based on the Android smart phone. The system uses some technologies including the active electrode, the WiFi wireless transmission, the multi-scale permutation entropy (MPE) algorithm, the back-propagation (BP) neural network algorithm, etc. Moreover, the software of Android mobile application can realize the processing and analysis of EEG data, the display of EEG waveform and the alarm of epileptic seizure. The system has been tested on the mobile phones with Android 2. 3 operating system or higher version and the results showed that this software ran accurately and steadily in the detection of epileptic seizure. In conclusion, this paper provides a portable and reliable solution for epileptic seizure monitoring in clinical and home applications. PMID:27382736

  16. Performance and limits of KNN-based positioning methods for GSM networks over leaky feeder in underground tunnels

    Pereira, Fernando; Moreira, Adriano; Ricardo, Manuel

    2012-01-01

    Localisation techniques have long been of major importance for safety systems and a lot of research has been conducted in the distributed computing field regarding its functionality and reliability. In the specific scenario of long yet narrow tunnels existing at CERN, localisation methods will enable a number of applications and processes to substantially reduce human intervention. In this article, we evaluate the use of fingerprinting techniques with GSM signal available throughout the LHC tunnel via a radiating cable and compare some methods to estimate the location. In the tests, 16 variants of the K-Nearest Neighbour algorithm, employing different distance weighting methods and fingerprint grouping functions, are taken into consideration and their performance is assessed with a specific rating algorithm. The existing GSM infrastructure and tunnel conditions seem to be favourable to the adoption of these fingerprinting methods. Nevertheless, significant variations in the signal have been observed which mig...

  17. A large-scale measurement of electromagnetic fields near GSM base stations in Guangxi, China for risk communication

    Radiofrequency (RF) electromagnetic field (EMF) exposure from wireless telecommunication base station antennae can lead to debates, conflicts or litigations among the adjacent residents if inappropriately managed. This paper presents a measurement campaign for the GSM band EMF exposure in the vicinity of 827 base station sites (totally 6207 measurement points) in Guangxi, China. Measurement specifications are designed for risk communication with the residents who previously complained of over-exposure. The EMF power densities with the global positioning system coordinate at each measured point were recorded. Compliance with the International Commission on Non-Ionizing Radiation Protection guidelines and Chinese environmental EMF safety standards was studied. The results show that the GSM band EMF level near the base stations is very low. The measurement results and the EMF risk communication procedures positively influence public perception of the RF EMF exposure from the base stations and promote the exchange of EMF exposure-related knowledge.

    2013-03-01

    Full Text Available It is likely that about one out of many large companies systematically monitors the computer, internet, or email use of its users employees. There are over hundred’s different products available today that will let organizations see what their users do at work on their "personal" computers, in their email, and on the internet. But what do such numbers really mean? What does company monitoring of user/employee email, internet, and computer usage actually look like? What sorts of things can an organization/companysee users do at their computers, and what sorts of computer activities are currently invisible to workplace monitoring? This admittedly document attempts to propose, as concretely as possible what "Informational Flow" on internet and computer usage looks like: its extent, the key concepts involved, and the forces driving its adoption. The keylogging program logs all keystrokes (aka Keystroke Logging along with the name of the application in which the keystrokes were entered. Using keylogger we prevent the miscellaneous use of system. Using this we capture all information in text and image form.

  1. Monitoring System For Improving Radiation Safety Management

    Medi SMARTS (Medical Survey Mapping Automatic Radiation Tracing System), a gamma radiation monitoring system, was installed in a nuclear medicine department. In this paper the evaluation of the system's ability to improve radiation safety management is presented. The system is based on a state of the art software that continuously collects on line radiation measurements for display, analysis and logging. Radiation is measured by GM tubes; the signal is transferred to a data processing unit and then via an RS-485 communication line to a computer. The system automatically identifies the detector type and its calibration factor, thus providing compatibility, maintainability and versatility when changing detectors. Radiation levels are displayed on the nuclear medicine department map at six locations. The system has been operating continuously for more than one year, documenting abnormal events caused by routine operation or failure incidents. In cases where abnormal working conditions were encountered, an alarm message was sent automatically to the supervisor via his tele-pager. An interesting issue observed during the system evaluation, was the inability to distinguish between high radiation levels caused by proper routine operation and those caused by safety failure incidents. The solution included examination of two parameters, radiation levels as well as their duration period. A careful analysis of the historical data, applying the appropriated combined parameters determined for each location, verified that such a system can identify abnormal events, provide alarms to warn in case of incidents and improve standard operating procedures

  2. GSM microwaves and 50 Hz electromagnetic field induce stress response but not apoptosis in human lymphocytes from hypersensitive and healthy persons

    We used specific conditions of exposure to microwaves from a GSM (global system for mobile communication) mobile phone (915 MHz, SAR=0.4 mW/g) and 50 Hz electromagnetic field (EMF, 15 μT amplitude) to investigate the response of lymphocytes from healthy subjects and from persons reporting hypersensitivity to EMF. The groups of hypersensitive and healthy donors were matched by gender and age and the data were analyzed in blind. The changes in chromatin conformation were measured with the method of anomalous viscosity time dependencies (AVTD). 53BP1 protein, which has been shown to co-localize in foci with DNA double strand breaks (DSB), was analyzed by immunostaining in situ. Exposure either to GSM microwaves or EMF/50 Hz resulted in significant condensation of chromatin, which was similar to the effect of heat shock at 41deg C. These effects varied between donors with a trend for prolonged condensation of chromatin in the cells from hypersensitive subjects. Cells from subjects, which were classified as pronounced hypersensitivity, responded to GSM /ELF stronger than cells from matched control subjects, but these differences in responses need to be confirmed in a larger study group. Neither GSM nor ELF exposure induced formation of 53BP1 foci. In contrary, distinct decrease in background level of 53BP1 signaling was observed upon these exposures as well as after heat shock treatments. This decrease correlated with the AVTD data and may indicate decrease in accessibility of 53BP1 to antibodies because of stress-induced chromatin condensation. No apoptosis was induced by exposure to ELF/50 Hz and GSM microwaves. In conclusion, ELF magnetic fields and GSM microwaves under specified conditions of exposure induced stress response in lymphocytes from healthy and hypersensitive donors

  3. Subcritical reactivity monitoring in accelerator driven systems

    In this paper, an absolute measurements technique for the subcriticality determination is presented. The development of accelerator driven systems (ADS) requires the development of methods to monitor and control the subcriticality of this kind of system, without interfering with its normal operation mode. This method is based on the stochastic neutron and photon transport theory that can be implemented by presently available neutron transport codes. As a by-product of the methodology a monitoring measurement technique has been developed and verified using two coupled Monte Carlo programs. The first one, LAHET, simulates the spallation collisions and the high energy transport and the other, MCNPDSP, is used to estimate the counting statistics from neutron ray counter in fissile system, and the transport for neutrons with energies less than 20 Mev. Through the analysis of the counter detectors it is possible to determine the kinetics parameters and the keff value. We present two different ways to obtain these parameters using the accelerator or using a Cf-252 source. A good agreement between theory and simulations has been obtained with both sources

  4. Automatic Outdoor Monitoring System for Photovoltaic Panels

    2016-05-01

    Long-term acquisition of solar panel performance parameters, for panels operated at maximum power point in their real environment, is of critical importance in the photovoltaic research sector. However, few options exist for the characterization of non-standard panels such as concentrated photovoltaic systems, heavily soiled or shaded panels or those operating under non-standard spectral illumination; certainly, it is difficult to find such a measurement system that is flexible and affordable enough to be adopted by the smaller research institutes or universities. We present here an instrument aiming to fill this gap, autonomously tracking and maintaining any solar panel at maximum power point while continuously monitoring its operational parameters and dissipating the produced energy without connection to the power grid. The instrument allows periodic acquisition of current-voltage curves to verify the employed maximum power point tracking approach. At the same time, with hardware schematics and software code being provided, it provides a flexible open development environment for the monitoring of non-standard generators like concentrator photovoltaic systems and to test novel power tracking approaches. The key issues, and the corresponding solutions, encountered in the design are analyzed in detail and the relevant schematics presented.

    Recent structural health monitoring techniques have focused on developing global sensor systems that can detect damage on large structures. The approach presented here uses a piezoelectric sensor array system that mimics the biological nervous system architecture to measure acoustic emissions and dynamic strains in structures. The advantage of this approach is that the number of channels of data acquisition used for an N-by-N sensor array can be reduced from N2 to 2N. For large arrays the number of data acquisition channels is tremendously reduced. When transient damage events occur on the structure, the array output time histories can be recorded and the location of the excitation can be accurately determined using combinatorial logic. A trade-off is the difficulty of extracting individual sensor time histories from the array outputs without a neural network or a regressive technique. Only the sums of the sensor strains of each row and column can be exactly calculated using the voltage outputs of the array. The array approach allows efficient use of data acquisition instrumentation for structural health monitoring. Applications for the sensor array include crack and delamination detection, dynamic strain measurement, impact detection, and localization of damage on large complex structures.

  6. Monitored Retrievable Storage System Requirements Document

    This Monitored Retrievable Storage System Requirements Document (MRS-SRD) describes the functions to be performed and technical requirements for a Monitored Retrievable Storage (MRS) facility subelement and the On-Site Transfer and Storage (OSTS) subelement. The MRS facility subelement provides for temporary storage, at a Civilian Radioactive Waste Management System (CRWMS) operated site, of spent nuclear fuel (SNF) contained in an NRC-approved Multi-Purpose Canister (MPC) storage mode, or other NRC-approved storage modes. The OSTS subelement provides for transfer and storage, at Purchaser sites, of spent nuclear fuel (SNF) contained in MPCs. Both the MRS facility subelement and the OSTS subelement are in support of the CRWMS. The purpose of the MRS-SRD is to define the top-level requirements for the development of the MRS facility and the OSTS. These requirements include design, operation, and decommissioning requirements to the extent they impact on the physical development of the MRS facility and the OSTS. The document also presents an overall description of the MRS facility and the OSTS, their functions (derived by extending the functional analysis documented by the Physical System Requirements (PSR) Store Waste Document), their segments, and the requirements allocated to the segments. In addition, the top-level interface requirements of the MRS facility and the OSTS are included. As such, the MRS-SRD provides the technical baseline for the MRS Safety Analysis Report (SAR) design and the OSTS Safety Analysis Report design

    2016-09-06

    Generally, the present disclosure is directed to gas monitoring systems that use inductive power transfer to safely power an electrically passive device included within a nuclear material storage container. In particular, the electrically passive device can include an inductive power receiver for receiving inductive power transfer through a wall of the nuclear material storage container. The power received by the inductive power receiver can be used to power one or more sensors included in the device. Thus, the device is not required to include active power generation components such as, for example, a battery, that increase the risk of a spark igniting flammable gases within the container.

  17. The Pajarito Monitor: a high-sensitivity monitoring system for highly enriched uranium

    The Pajarito Monitor for Special Nuclear Material is a high-sensitivity gamma-ray monitoring system for detecting small quantities of highly enriched uranium transported by pedestrians or motor vehicles. The monitor consists of two components: a walk-through personnel monitor and a vehicle monitor. The personnel monitor has a plastic-scintillator detector portal, a microwave occupancy monitor, and a microprocessor control unit that measures the radiation intensity during background and monitoring periods to detect transient diversion signals. The vehicle monitor examines stationary motor vehicles while the vehicle's occupants pass through the personnel portal to exchange their badges. The vehicle monitor has four groups of large plastic scintillators that scan the vehicle from above and below. Its microprocessor control unit measures separate radiation intensities in each detector group. Vehicle occupancy is sensed by a highway traffic detection system. Each monitor's controller is responsible for detecting diversion as well as serving as a calibration and trouble-shooting aid. Diversion signals are detected by a sequential probability ratio hypothesis test that minimizes the monitoring time in the vehicle monitor and adapts itself well to variations in individual passage speed in the personnel monitor. Designed to be highly sensitive to diverted enriched uranium, the monitoring system also exhibits exceptional sensitivity for plutonium

    2015-04-01

    Full Text Available Accurate characterization of radio communication channel through key parameters and a mathematical model is important for predicting signal coverage, channel efficiency and capacity. Outdoor path loss propagation modeling plays a fundamental role in planning and designing of every radio communication link. The ultimate goal in this work is to develop a model that can help in planning better global system for mobile communication (GSM network and to address complain of poor quality of service by the subscribers, within Kaduna town. Outdoor measurements were conducted to precision at 900MHz, the overall average path loss detected were; 93.70, 88.50, 98.27 and 103.15 dB for MTN, Glo, Airtel, and Etisalat networks, respectively. The differences may be attributed to the nature of the environment or the location or antenna heights of the respective base stations (BSs, or weather fluctuations. However, the variance of these average values lies between 10 to 20dB, which is within the acceptable range. The empirical model developed from Log-normal shadowing model, which has a unique advantage of accounting for shadowing effects that may be caused by varying degree of clutter between transmitter and receiver, may be used in planning and optimization of GSM service within Kaduna town.

  19. Short GSM mobile phone exposure does not alter human auditory brainstem response

    Thuróczy György

    2007-11-01

    Full Text Available Abstract Background There are about 1.6 billion GSM cellular phones in use throughout the world today. Numerous papers have reported various biological effects in humans exposed to electromagnetic fields emitted by mobile phones. The aim of the present study was to advance our understanding of potential adverse effects of the GSM mobile phones on the human hearing system. Methods Auditory Brainstem Response (ABR was recorded with three non-polarizing Ag-AgCl scalp electrodes in thirty young and healthy volunteers (age 18–26 years with normal hearing. ABR data were collected before, and immediately after a 10 minute exposure to 900 MHz pulsed electromagnetic field (EMF emitted by a commercial Nokia 6310 mobile phone. Fifteen subjects were exposed to genuine EMF and fifteen to sham EMF in a double blind and counterbalanced order. Possible effects of irradiation was analyzed by comparing the latency of ABR waves I, III and V before and after genuine/sham EMF exposure. Results Paired sample t-test was conducted for statistical analysis. Results revealed no significant differences in the latency of ABR waves I, III and V before and after 10 minutes of genuine/sham EMF exposure. Conclusion The present results suggest that, in our experimental conditions, a single 10 minute exposure of 900 MHz EMF emitted by a commercial mobile phone does not produce measurable immediate effects in the latency of auditory brainstem waves I, III and V.
