    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...

    Full Text Available The majority applications of pollution monitoring systems are in industries. The control of the parameters which causes pollution and deteriorates the industrial and natural environment pattern is a great challenge and has received interest from industries especially in Petro chemical industries, Paper making industries, Water treatment industries and Sugar manufacturing industries. The main objective of our project is to design an efficient and robust system to control the parameters causing pollution and to minimize the effect of these parameters without affecting the plant or natural environment. The proposed methodology is to model a system to read and monitor pollution parameters and to inform pollution control authorities when any of these factors goes higher than industry standards. A mechanism using GSM and LabVIEW is introduced in this proposed methodology, which will automatically monitor when there is a disturbance affecting the system. The system is implemented using LabVIEW software. The system investigates level of pH in industry effluents, level of CO gas released during industry process and temperature of the machineries. With the design of GSM, the signals can be effectively transferred and the actions in these cases can still be made accurate and effective. Thus through this project we try to prove that control of pollution can be computed and the data can be transferred online. Our proposed method is more accurate to derive the desired parameters. LabVIEW is the powerful and versatile programming language for operating and controlling the pollution monitoring system and GSM is suitable for interactive environment for signal transfer.

  20. Development of low cost wireless radiation monitoring station using GSM network

    International Nuclear Information System (INIS)

    SMS or Short Message Service is a mean of GSM wireless communication that allow text messages to be sent to and from mobile cell phones. While SMS communication is mainly utilized at personal level or person to person basis; the usage of SMS can be extended into nuclear application specifically in radiation monitoring. This paper explains the development of a wireless station assembled by using a recycled Siemens M50 cell phone as substitutes to GSM modem, a PIC micro controller, and MINT-ISG home made digital survey meter at the remote transmitting site. While at the receiving end; an online monitoring system is set-up by using a Bluetooth enabled cell phone, a Bluetooth dongle, and a PC with Labview 8.0 software written as the Data logger which also served as the PC-Bluetooth interface platform. Wireless station at the remote area operates by continuously sending SMS in every 3 minutes to a predefined cellular number located at the monitoring system. The SMS consists of 6 data which individually is a survey meter readings recorded at each 30 seconds duration. At the receiver, Data logger program will retrieve the SMS from the cell phone via Bluetooth and extract the original 6 readings to be displayed on PC. The system has been successfully tested to detect and log radiation data for extended period of time. (Author)

    Full Text Available A RFID, GPS & GSM Based Vehicle Tracking and Employee Security System combine the installation of an electronic device in a vehicle, with purpose-designed computer software to enable the company to track the vehicle's location. In vehicle tracking systems we use Global Positioning System (GPS technology for locating the vehicle. Vehicle information can be viewed on electronic maps via the Internet or specialized software. Due to recently happened mishaps such as burglary, rape cases etc., the employee safety, esp. for the women employees, has become a number one priority for most of the companies. Even though the companies take good precautions to ensure that its employees are safe, there are some serious loop holes in the existing system. Firstly there is no full proof mechanism to track the outsiders to avoid this kind of problem we are going to implement a system that provides more security to the employee. The car Unit is placed inside the car .When the car picks up the employee; he/she needs to swap the RFID card. The micro controller matches the RFID card no. with its database records and sends the employee’s id, cab id & the cab position co-ordinates to the company unit via GSM module. The GSM Modem will receive the message through GSM in the company unit. If employee finds himself/herself in a problem, he/she will press the button. Microcontroller will detect the action & sends a signal to the GSM which will coordinate with to the company unit and police. Microcontroller will also send a signal to the relay which will turn off the car ignition & stop the car. The GSM Modem will receive the message. This message will then be transferred to the computer through the serial port. The employee name, employee id & cab position coordinates (longitude and latitude get displayed on computer. Once the data is obtained on the computer, it can be used for further analysis. In this way the company unit keeps a track of the vehicle. This will be a much simpler and low cost technique compared to others.

    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.

    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.

    Mobile phones are two-way radios that emit electromagnetic radiation in microwave range. As the number of mobile phone users has reached 6 billion, the bioeffects of exposure to mobile phone radiation and mobile phone electromagnetic interference with electronic equipment have received more attention, globally. As self-monitoring of blood glucose can be a beneficial part of diabetes control, home blood glucose testing kits are very popular. The main goal of this study was to investigate if radiofrequency radiation emitted from a common GSM mobile phone can alter the accuracy of home blood glucose monitors. Forty five female nondiabetic students aged 17-20 years old participated in this study. For Control-EMF group (30 students), blood glucose concentration for each individual was measured in presence and absence of radiofrequency radiation emitted by a common GSM mobile phone (HTC touch, Diamond 2) while the phone was ringing. For Control- Repeat group (15 students), two repeated measurements were performed for each participant in the absence of electromagnetic fields. The magnitude of the changes between glucose levels in two repeated measurements (|?C|) in Control-Repeat group was 1.07 ± 0.88 mg/dl while this magnitude for Control-EMF group was 7.53 ± 4.76 mg/dl (P mobile phones has an adverse effect on the accuracy of home blood glucose monitors. We suggest that mobile phones should be used at least 50 cm away from home blood glucose monitors. PMID:25505778

    Full Text Available In mobile network, a deviation of cell coverage area influences many network performance indexes. Cell coverage analyses are vital to network optimization. The traditional check method is DT (Drive Test or FSP (Field Strength Prediction by manpower which costs much time and resources. This paper presents an intelligent multiple factors analysis method on cell coverage, and designs the relevant software system based on GIS platform. This system derives a cell coverage analysis chart and identifies the cells with cross-boundary coverage or poor coverage problem by collecting a huge number of mobile phone measure data in OMC and analyzing multiple factors based on the measure data and the basic data of cells. The measure data analysis aims to compute signal level distribution, sample point distribution, category of interferences. The basic data of cells includes neighborhood relationship, azimuth ward, location and distance between two cells. The base station site level can be computed from the basic data of cells by the triangulation method. The calculation and analysis results are presented in the map based on GIS platform to improve visualization. This method and system are validated by a large number of actual datasets from an in-service GSM network. Contrast with the traditional cell analysis method, this method and system demonstrate advantages in intelligence, accuracy, timeliness, and visualization.

    Context-aware applications have been gaining huge interest in the last few years. With cell phones becoming ubiquitous computing devices, cell phone localization has become an important research problem. In this paper, we present CellSense, a prob- abilistic RSSI-based fingerprinting location determi- nation system for GSM phones. We discuss the chal- lenges of implementing a probabilistic fingerprinting localization technique in GSM networks and present the details of the CellSense systemand how it addresses these challenges. We then extend the proposed system using a hybrid technique that combines probabilistic and deterministic estimation to achieve both high ac- curacy and low computational overhead.Moreover, the accuracy of the hybrid technique is robust to changes in its parameter values. To evaluate our proposed system, we implemented CellSense on Android-based phones. Results from two different testbeds, represent- ing urban and rural environments, for three differ- ent cellular providers show that Ce...

    1- Your present GSM subscription (SIM card) will no longer be valid as from the 5th January 2004. 2- Short numbers 16xxxx (where xxxx are your current last 4 digits) will remain valid. 3- Your new number from outside will then be +4176 487xxxx. 4- From the 20th December to the 4th January 2004 (CERN's official holiday) your GSM will be unusable underground. Nota bene: Due to the high costs involved calls from outside will not be automatically diverted to a "combox" indicating that your number has changed. It is therefore up to you to inform your correspondents of your GSM number change. For further information on the GSM Migration see the CERN home page: http://cern.ch/

    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.

The paper “GSM and internet based home security” is mainly aims to implements the emerging applications of the GSM technology. Using GSM networks, a controlling system has been proposed that will act as an embedded system which can monitor and control appliances and other devices locally using built-in input and output peripherals. Remotely the system allows the user to effectively monitor and control the house/office appliances and equipments via the mobile phone set by sending commands in the form of SMS messages and receiving the appliances status. This project concept is to use keywords as SMS and processing it further as required to perform several operations. The operation to be performed depends up on the nature of the SMS sent or keyword used. The principle in which the project is based is fairly simple. First, the sent SMS will be received at the receiver mobile station and then the required control signal is generated and sent to the intermediate hardware that we have designed according to the command received in form of the sent message. In this we are using internet also to send messages through internet we can controldevices

    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.

    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.

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.

    Full Text Available Instead of having the single application in a system it is better to have multiple applications such that the user can run the vehicle safely and can avoid the accident. Here in this paper we are using a combination of different technologies such as GPS, GSM Technology. Now a days drunken drivers are increasing enormously. Due to this drunken driving, accidents are occurring at high rates. The main reason for driving drunk is that the police are not able to check each and every car. So we need an effective system which checks whether the driving person has drunken or not. Then it checks the seat belt is inserted properly or not. Vehicle will be automatically off when the system senses alcohol or seat belt is not properly inserted. Including with above applications, there is a CO sensor for monitoring the CO level which is emitted from the car and ultrasonic sensor for obstacle detection. The car is embedded with all the above technologies. If suddenly the vehicle met with an accident automatically the information will be transmitted to the nearest control room/medical rescue team by using an advanced GSM device which better suits for faster communication.

    2004-01-01

    Telemedicine is taking a step forward with the efforts of team members from the NASA Glenn Research Center, the MetroHealth campus of Case Western University, and the University of Akron. The Arrhythmia Monitoring System is a completed, working test bed developed at Glenn that collects real-time electrocardiogram (ECG) signals from a mobile or homebound patient, combines these signals with global positioning system (GPS) location data, and transmits them to a remote station for display and monitoring. Approximately 300,000 Americans die every year from sudden heart attacks, which are arrhythmia cases. However, not all patients identified at risk for arrhythmias can be monitored continuously because of technological and economical limitations. Such patients, who are at moderate risk of arrhythmias, would benefit from technology that would permit long-term continuous monitoring of electrical cardiac rhythms outside the hospital environment. Embedded Web Technology developed at Glenn to remotely command and collect data from embedded systems using Web technology is the catalyst for this new telemetry system (ref. 1). In the end-to-end system architecture, ECG signals are collected from a patient using an event recorder and are transmitted to a handheld personal digital assistant (PDA) using Bluetooth, a short-range wireless technology. The PDA concurrently tracks the patient's location via a connection to a GPS receiver. A long distance link is established via a standard Internet connection over a 2.5-generation Global System for Mobile Communications/General Packet Radio Service (GSM/GPRS)1 cellular, wireless infrastructure. Then, the digital signal is transmitted to a call center for monitoring by medical professionals.

    The proximity of a mobile phone to the human eye raises the question as to whether radiofrequency (RF) electromagnetic fields (EMF) affect the visual system. A basic characteristic of the human eye is its light sensitivity, making the visual discrimination threshold (VDThr) a suitable parameter for the investigation of potential effects of RF exposure on the eye. The VDThr was measured for 33 subjects under standardized conditions. Each subject took part in two experiments (RF-exposure and sham-exposure experiment) on different days. In each experiment, the VDThr was measured continuously in time intervals of about 10 s for two periods of 30 min, having a break of 5 min in between. The sequence of the two experiments was randomized, and the study was single blinded. During the RF exposure, a GSM signal of 902.4 MHz (pulsed with 217 Hz) was applied to the subjects. The power flux density of the electromagnetic field at the subject location (in the absence of the subject) was 1 W/m(2), and numerical dosimetry calculations determined corresponding maximum local averaged specific absorption rate (SAR) values in the retina of SAR(1 g) = 0.007 W/kg and SAR(10 g) = 0.003 W/kg. No statistically significant differences in the VDThr were found in comparing the data obtained for RF exposure with those for sham exposure. PMID:17654531

    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.

    Francis Enejo Idachaba

    2011-10-01

    Full Text Available The high rate of kidnapping in Nigeria is fueled inability of security agencies to quickly identify the location of the kidnapped persons. This system combines the position location capabilities of the GPS (Global Positioning System to identify the current location of the kidnapped person or stolen items. These coordinates are time stamped, accessed by the microcontroller and sent to predetermine mobile phones via the GSM network. The GPS readings are accessed at short regular intervals but only the latest five readings are stored per time and these five readings are transmitted on demand by the GSM modem under the control of the Microcontroller upon the receipt of a location request SMS. The system monitors the GSM signal strength as the tracked object or person moves and when the GSM received signal strength falls below a predetermined threshold value, an alert together with the last five location data is sent to the monitoring mobile phones and the control center notifying them that the tracked object is approaching an area without GSM coverage. The system is designed to be permanently on and it is run on batteries that can last for very long periods before requiring a recharge. The unit is designed to be attached to the clothing or strapped on the tracked person in such a way that it can not be easily identified or removed. It also has a panic button which can be activated during an emergency to send the location data to the predetermined numbers.

So it was difficulty in popularizing in with low cost and at the circumstance of infrastructure less or infrastructure destruction. By utilizing the wireless technique to transmit information between medical sensor and monitoring control center, the free space of patients is enlarged, and the efficiency of the modern management of hospitals is improved. Besides, the problem of the lack of unremitted real-time care for every patient, which is caused by the shortage of health care members, is also solved. Therefore, the portable wireless medical monitoring products will become popular in the future market. Nowadays, there are various kinds of wireless communication protocols. But since the main task of a monitoring terminal is to realize the transmission of signals such as heart rate, body temperature, and calling signals---the data traffic is not heavy. In this paper, the real-time monitoring system for monitoring the patient’s physical states using wireless sensor network technology is illustrated.

    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.

    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.

  12. Safety system status monitoring

    International Nuclear Information System (INIS)

    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

    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.

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

    International Nuclear Information System (INIS)

    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)

  18. Redundant instrument monitoring system

    International Nuclear Information System (INIS)

    This paper reports on the instrumentation design at the San Onofre Nuclear Generating Station (SONGS), Units 2 and 3, which includes the monitoring of important process parameters by several redundant instrument channels. The Southern California Edison Company (SCE) has installed a system to monitor the calibration status of selected redundant instrumentation in Units 2 and 3 at SONGS. The purpose of the system is to enable identification of instruments which are preforming properly and those whose performance is questionable while the plant in on-line. This information can then be used to justify the calibration of only those instruments that are questionable, thereby reducing the number of calibrations that are required during refueling outages. The Redundant Instrument Monitoring System (RIMS) collects data from the in-plant computer systems, the Plant Monitoring and Critical Functions Monitoring Systems for both Units at 12 minutes intervals. The signals from instrument which monitor the same process parameter are grouped. The average value for each redundant group is then calculated and the deviation of each parameter from the average is determined in terms of percent of calibrated span. Appropriate weighing factors are utilized, based on individual instrument accuracies, to determine the best estimate of the process parameter. The deviations are then trended over time to evaluate changes in the instrumentation calibration status. The time history of these deviations are permanently stored on an optical disk for retrieval at any future date. Result from RIMS are compared with tradition calibration methods at refueling intervals to validate RIMS operation

    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.

    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. System health monitoring

    International Nuclear Information System (INIS)

    Well designed large systems include many instrument taking data. These data are used in a variety of ways. They are used to control the system and its components, to monitor system and component health, and often for historical or financial purposes. This paper discusses a new method of using data from low level instrumentation to monitor system and component health. The method uses the covariance of instrument outputs to calculate a measure of system change. The method involves no complicated modeling since it is not a parameter estimation algorithm. The method is iterative and can be implemented on a computer in real time. Examples are presented for a metal lathe and a high efficiency particulate air (HEPA) filter. It is shown that the proposed method is quite sensitive to system changes such as wear out and failure. The method is useful for low level system diagnostics and fault detection

  7. Benzene Monitor System report

    International Nuclear Information System (INIS)

    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/PRclose 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 ampersand 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)

    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.

    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...

    2010-06-15

    The Lucerne University of Applied Sciences and Arts - Lucerne School of Engineering and Architecture conducted field tests with an uninterruptible power supply (UPS) with fuel cell technology since January 2006. The project took place in collaboration with the industrial partners Swisscom (Schweiz) AG, as a user of UPS-systems in telecommunications and the American Power Conversion Corporation as a producer and market leader of UPS-Systems. In this project, the lead-acid batteries were replaced by a PEM fuel cell system. The delayed start-up behaviour of the fuel cell was bridged with supercapacitor technology. The system was connected to an existing working base station of a telecommunication installation, which was installed on the roof of the Lucerne School of Engineering and Architecture in Horw. Hydrogen was provided by two pressurized tanks. The full quantity of hydrogen assured a stand-alone operation for about 6 hours under the load of the telecommunication base station. The field test included monthly grid failure simulations of 5x5 minutes and 2x20 minutes power failures. Also during grid failure simulations for more than 4 hours and during two real outages up to one and a half hour the system provided the demanded power. The field test was performed for a period of three and a half years. Excellent results of the approximately 350 start-up's confirm the functionality, reliability and performance of the system. Under the load of the base station the fuel cell system started with a reliability of 100%. At the end of the tests a decrease of the fuel cell voltage of about 3.3% was measured. The fuel cell system was still fully operational at this time. An amount of energy of about 470 kWh was provided. In addition to the field test, the environmental impact of the lead-acid batteries, which are normally used, and of the fuel cell system was investigated. The comparison between the fuel cell system and lead-acid batteries without recycling showed a reduction of CO{sub 2}-equivalents of nearly 90% within a life cycle of 10 years. In comparison with lead-acid batteries with recycling there is a reduction of more than 80%. During the project period the market changed. An increasing number of fuel cell producers and UPS suppliers became aware that the application of fuel cell's as a back-up system respond to critical market demands. They developed ready-to-market products which are suited to achieve early commercialisation success. Hence for the fuel cell UPS application it is no longer the question of functionality but of a successful market entry. (authors)

    2007-07-01

    The University of applied sciences HTA Lucerne designed a prototype of an uninterruptible power supply (UPS) with Fuel Cell technology instead of lead-acid batteries and put it into operation. The delayed start-up of the Fuel Cell was bridged with ultra capacitor technology. In a first project stage the system was designed, assembled and tested in laboratory. In a second stage the installation was connected to a real base station of a telecommunication antenna and put to field tests for one year. The field test included monthly simulations of power failure with antenna load of about 2.4 kW as well as tests with external load up to 8.5 kW to establish the characteristic diagram. Hydrogen was provided by two 50 l pressure tanks. The full quantity of hydrogen secured a stand-alone operation of the Fuel Cell system for about 6 hours under antenna load. The results of the 101 grid-failure simulations demonstrate a very reliable start-up behaviour of the Fuel Cell System. Also during a real power failure due to a thunderstorm the installation provided the demanded power without any problem. The total duration of operation of the Fuel Cell during the field tests was 39 hours. No degradation could be noticed.

  16. Nonlinear Filtering for Hybrid GPS/GSM Mobile Terminal Tracking

    Directory of Open Access Journals (Sweden)

    Carsten Fritsche

    2010-01-01

    Full Text Available The Global Positioning System (GPS has become one of the state-of-the-art location systems that offers reliable mobile terminal (MT location estimates. However, there exist situations where GPS is not available, for example, when the MT is used indoors or when the MT is located close to high buildings. In these scenarios, a promising approach is to combine the GPS-measured values with measured values from the Global System for Mobile Communication (GSM, which is known as hybrid localization method. In this paper, three nonlinear filters, namely, an extended Kalman filter, a Rao-Blackwellized unscented Kalman filter, and a modified version of the recently proposed cubature Kalman filter, are proposed that combine pseudoranges from GPS with timing advance and received signal strengths from GSM. The three filters are compared with each other in terms of performance and computational complexity. Posterior Cramér-Rao lower bounds are evaluated in order to assess the theoretical performance. Furthermore, it is investigated how additional GPS reference time information available from GSM influences the performance of the hybrid localization method. Simulation and experimental results show that the proposed hybrid method outperforms the GSM method.

    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 of environments including summer in Arizona to winter above 9000' in the mountains of southern Colorado. Statistically based on-board processing is used for detection, arrival time picking, back azimuth estimation and magnitude estimates from coda waves and acoustic signals.

  20. Sensor Based Effective Monitoring of Coal Handling System (CHS

    2013-06-01

    Full Text Available Coal level detection is an important aspect to assess the performance of a coal-fired power plant. Coal has to be transported, via a coal handling system. The fuel in a coal-fired power plant is stored in silos, bunkers or stock piles. Coal is stored in silos in a small plant, Bunkers for handling a day’s operation and Stock piling methods for large plants. So, fuel handling had to done efficiently. To accurately sense the coal height, Real-time feedback is deployed within the bunker or stock pile. The real time range information is then fedback to the control system. Of the different types of ranging sensors, radar based system is used. Also a real-time temperature monitoring system is developed to protect the coal. The range and temperature data from sensors are sent to the main system through GSM modem by means of SMS. The range information is used to start the conveyor belt to draw the coal from coal yard. If the temperature exceeds the limit, the SMS will be sent through the software or it will call the respective person to monitor the process. A fire sensor is also used to extinguish the fire by initiating the water spraying system. A PIC Microcontroller is interfaced all the sensors for effective handling of thermal power plant.

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

    Science.gov (United States)

    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.

  3. Airborne monitoring system

    International Nuclear Information System (INIS)

    A complete system for tracking, mapping, and performing a composition analysis of a radioactive plume and contaminated area was developed at the NRCN. The system includes two major units : An airborne unit for monitoring and a ground station for analyzing. The airborne unit is mounted on a helicopter and includes file following. Four radiation sensor, two 2'' x 2'' Nal (Tl) sensors horizontally separated by lead shield for mapping and spectroscopy, and two Geiger Mueller (GM) tubes as part of the safety system. A multichannel analyzer card is used for spectroscopy. A navigation system, based on GPS and a barometric altitude meter, is used to locate the plume or ground data. The telemetry system, consisting of a transceiver and a modem, transfers all the data in real time to the ground station. An industrial PC (Field Works) runs a dedicated C++ Windows application to manage the acquired data. An independent microprocessor based backup system includes a recorder, display, and key pad. The ground station is based on an industrial PC, a telemetry system, a color printer and a modem to communicate with automatic meteorology stations in the relevant area. A special software controls the ground station. Measurement results are analyzed in the ground station to estimate plume parameters including motion, location, size, velocity, and perform risk assessment. (authors)

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

    International Nuclear Information System (INIS)

    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 power is required to achieve measurable SAR. In Burkhardt et al an analysis is performed of the exposure within a TEM cell. In particular, for thin samples, an analytical formulation is derived that provides SAR as a function of h. The applicability of the formula is limited in the current work because the sample height is relatively large in the interests of producing acceptable SAR with the available RF power. Consequently, a finite-difference model of the exposure geometry was developed using the XFDTD package. A comparison with the Burkhardt formula showed that the accuracy of the formula diminishes for thicknesses greater than h = 4 mm. The XFDTD model also highlights the desired uniformity of the SAR on the bottom level where the cells are present. To simplify modeling, it was important that plane wave conditions be maintained in the exposure chamber. These conditions exist within a TEM cell design as long as the absorbing volume is not too thick, presenting another constraint on sample thickness and hence power efficiency. A further constraint on thickness was that the nutrient media layer needed to be sufficiently thin to allow diffusion to the cells of the CO2 atmosphere of the chamber in which the entire exposure system is incubated. Based on considerations of physical size and required field characteristics, a modified transverse electromagnetic TEM was chosen. Modifications included provision of adequate ventilation; access ports and inserts to allow placement of two standard 25 cm3 culture flasks so that the cell monolayer was positioned at the midpoint of the volume of the TEM cell; and fixtures to allow ingress and accurate location of the fluoroptic temperature probes used in the SAR calibration of the TEM cell. The TEM cell is supplied with a signal that simulates the transmissions from a standard GSM mobile phone. Maximum peak RMS power to the TEM cell is 20 W, with average RMS power of 2.5 W. Measured return loss is greater than 30 dB. Total absorbed power with the TEM cell loaded with two flasks containing media is less than 4% of forward power

    2013-04-01

    Full Text Available The Idea of Designing an Innovative Anti-detaining student monitoring system is born with the observation of student’s behavior in real life. Most of the students will be bunking the classes, most of the time and due to attendance shortage finally gets detained. And he will be losing his career most of the times. The parents will not be aware until the student crosses the attendance dead line. The purpose of this project is to develop a student monitoring and guardian alert system maintain the attendance of students who are mostly irregular to classes. After observing the attendance of the students in the first month, students whose attendance is below the margin level, (approx. below 40 to 50% are filtered out and those students should be registered in the system with their identity particulars, finger prints, mobile numbers of their guardians etc…every day the enrolled students has to put their attendance at periodical intervals of the day. If the student fails to put attendance, immediately a SMS message using GSM modem will be sent to the guardian and student mobiles. The main objective of the system is to reduce the students who are getting detained every year.

    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.

    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...

  10. Route 66: Passively Breaking All GSM Channels

    DEFF Research Database (Denmark)

    Vejre, Philip S.; Bogdanov, Andrey

    2014-01-01

    The A5/2 stream cipher used for encryption in the GSM mobile phone standard has previously been shown to have serious weaknesses. Due to a lack of key separation and flaws in the security protocols, these vulnerabilities can also compromise the stronger GSM ciphers A5/1 and A5/3. Despite GSM's huge impact in the field, only a small selection of its channels have been analyzed. In this paper, we perform a complete practical-complexity, ciphertext-only cryptanalysis of all 66 encoded GSM channels. Moreover, we present a new passive attack which recovers the encryption key by exploiting the location updating procedure of the GSM protocol. This update is performed automatically even when the phone is not actively used. Interestingly, the attack potentially enables eavesdropping of future calls.

  12. Plant monitor system

    International Nuclear Information System (INIS)

    An advanced control room complex for a nuclear power plant, including a discrete indicator and alarm system which is nuclear qualified for rapid response to changes in plant parameters and a component control system which together provide a discrete monitoring and control capability at a panel in the control room. A separate data processing system, which need not be nuclear qualified, provides integrated and overview information to the control room and to each panel, through CRTs and a large, overhead integrated process status overview board. The discrete indicator and alarm system and the data processing system receive inputs from common plant sensors and validate the sensor outputs to arrive at a representative value of the parameter for use by the operator during both normal and accident conditions, thereby avoiding the need for him to assimilate data from each sensor individually. The integrated process status board is at the apex of an information hierarchy that extends through four levels and provides access at each panel to the full display hierarchy. The control room panels are preferably of a modular construction, permitting the definition of inputs and outputs, the main machine interface, and the plant specific algorithms, to proceed in parallel with the fabrication of the panels, the installation of the equipment and the generic testing thereof.

    2014-01-01

    GSM is a synonym for a major success in wireless technology, achieving widespread use and high technology maturity. However, its future is questionable, as many stakeholders indicate that the GSM spectrum should be re-farmed for LTE. On the other hand, the advent of smart grid and the ubiquity of smart meters will require reliable, long-lived wide area connections. This motivates to investigate the potential of GSM to be evolved into a dedicated network for smart metering. We introduce simple mechanisms to reengineer the access control in GSM. The result is a system that offers excellent support for smart metering, as well as the other massive machine-to-machine traffic patterns that are envisioned in 3GPP.

  5. ERMS - Environmental Radiation Monitoring System

    International Nuclear Information System (INIS)

    A new Environmental Radiation Monitoring System (ERMS) has been developed in the NRCN as an extensive tool to be applied in case of nuclear malfunction or Nuclear Disposal Device (NDD) incident, as well as for routine radiation monitoring of the reactor's vicinity. The system collects real-time environmental data such as: gamma radiation, wind speed, wind direction, and temperature for monitoring purposes. The ERMS consists of a main Control Center and an array of monitoring stations. Fixed, environmental, gamma radiation monitoring stations are installed at the reactor's surroundings while portable stations can be posted rapidly along the wind direction, enhancing the spatial sampling of the radiation measurements and providing better hazard assessment at an emergency event. The presented ERMS, based on industrial standards for hardware and network protocols, is a reliable standalone system which upgrades the readiness to face a nuclear emergency event by supplying real-time, integrated meteorological and radiation data.

    Dumitrescu, Catalin; Nowack, Andreas; Padhi, Sanjay; Sarkar, Subir

    2010-04-01

    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.

  13. VoLTE Performance in Railway Scenarios : Investigating VoLTE as a Viable Replacement for GSM-R

    DEFF Research Database (Denmark)

    Sniady, Aleksander; SØnderskov, Morten

    2015-01-01

    GSM-Railways (GSM-R) is the current standard for railway voice and data communication. GSM-R provides railway specific voice services, such as Railway Emergency Call (REC). GSM-R provides also the European Train Control System (ETCS), which offers in-cab signaling and Automatic Train Protection (ATP). Despite these features and services, GSM-R has various major shortcomings. Therefore, alternative technologies are considered to replace GSM-R and become the next generation railway mobile communication network. 3GPP Long Term Evolution (LTE) is a likely candidate for GSM-R replacement. LTE is more efficient, flexible and offers much higher capacity, which allows the railway network to provide new communication-based applications for railways. Most of the research on LTE in railways has been focused on data-based railway applications (ETCS signaling and other). Nevertheless, voice communication is still a crucial service for railways. Regardless of its advantages, LTE can only become a railway communication technology if it provides voice communication fulfilling railway requirements. This paper presents how Voice over LTE (VoLTE) can be used to build railway communication services. Examples of Railway Emergency Call and One-to-One Call are provided. Service performance, in terms of call setup times and voice transmission quality, is analyzed in simulation scenarios modelling two railway scenarios in Denmark.

    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.

  17. No influence of acute RF exposure (GSM-900, GSM-1800, and UMTS) on mouse retinal ganglion cell responses under constant temperature conditions.

    Science.gov (United States)

    Ahlers, Malte T; Ammermüller, Josef

    2014-01-01

    Possible non-thermal effects of radio frequency electromagnetic fields (RF-EMF) on retinal ganglion cells were studied in vitro under conditions of constant temperature. Isolated mouse retinae were exposed to GSM-900, GSM-1800, and universal mobile telecommunication system (UMTS) RF-EMF applying specific absorption rates (SAR) of 0 (sham), 0.02, 0.2, 2, and 20?W/kg. Temperature was kept constant within ±0.5 to 1?°C for GSM-900 and ±0.5?°C for GSM-1800 and UMTS. Responses of retinal ganglion cells to light stimuli of three intensities (0.5, 16, and 445?lx) were recorded before, during, and up to 35?min after exposure. Experiments were performed under double-blind conditions. Changes in light responses during and after exposure were determined for each condition (RF-EMF; SAR value; light intensity) with respect to the responses before exposure, respectively. Changes were calculated using the Euclidian distance of the n-dimensional response vectors, respectively. Some changes already occurred during sham (0?W/kg) exposure, reflecting the intrinsic variability in retinal ganglion cell responses. Comparison of the distance values from sham exposure with those from actual exposure yielded no significant differences. In addition, linear regression analysis of the distance values versus SAR values yielded no consistent dependence of light response changes. From these results we conclude that RF-EMF exposure at three mobile phone frequencies (GSM-900, GSM-1800, UMTS) and SARs up to 20?W/kg has no acute effects on retinal ganglion cell responses under constant temperature conditions.

  19. Remote Tritium Air Monitoring System

    International Nuclear Information System (INIS)

    A versatile system for monitoring tritium in air has been installed in reactor buildings. The monitor provides quick estimates of tritium activity in the presence of gamma radiation. The system also provides a means for leak-checking the heavy-water moderator and blanket-gas systems associated with reactor operation. The monitor can sample widely separate areas or simultaneously average the activities from many areas. By using an arrangement of electrically- or manually-operated valves, samples can be selected from one or more points at a work site, or the size of the area being monitored by one system can be changed. This flexibility of sampling can be attained by valving locally or remotely. Meters provide for visual indication of air activity levels at the job site; alarms alert personnel to hazardous conditions. Recorders are used where a record of air activity in a work zone is needed, or where an audit of the work area is desired. The reliability and usefulness of air activity measurements have been improved and monitoring costs have been reduced by this development. (author)

    International Nuclear Information System (INIS)

    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, ?) 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 ?s 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

  2. Glovebox oxygen monitoring system

    International Nuclear Information System (INIS)

    This system is located in the Replacement Tritium Facility (RTF) at the Savannah River Site of the US Department of Energy. The basic system consists of an oxygen sensor module located inside the glovebox and a wall mounted panel located outside the glovebox that contains an electronics package that displays the oxygen level, displays alarms, and sends signals to a facility Distributed Control System (DCS). RTF is a new facility that will be used primarily to load and unload tritium reservoirs, and recycle the tritium for use in existing or new reservoirs. Tritium, an oderless, colorless, gas is a radioactive isotope of hydrogen that is used in modern thermonuclear weapons. Once on-line, RTF will replace other tritium facilities that have been in existence since the 1950's. Since the entire process at RTF is contained in nitrogen blanketed gloveboxes and features have been provided to recapture fugitive tritium, environmental releases and worker exposure to tritium will be reduced compared to the old facilities

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

    International Nuclear Information System (INIS)

    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

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

    Directory of Open Access Journals (Sweden)

    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.

    Filby, E.E.; Haskel, K.J.

    1998-03-01

    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.

    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.

    International Nuclear Information System (INIS)

    The work proposed in this presentation builds on the foundation set by the DTRA funded demonstration project begun in 2000 and completed in December of 2003. This previous work consisted of two phases whose overall objective was to install portal radiation monitors at four select ports-of-entry in Uzbekistan (Tashkent International Airport, Gisht-Kuprik (Kazakhstan border), Alat (Turkmenistan border), and Termez (Afghanistan border)) in order to demonstrate their effectiveness in preventing the illicit trafficking of nuclear materials. The objectives also included developing and demonstrating capabilities in the design, installation, operation, training, and maintenance of a radiation portal monitoring system. The system and demonstration project has proved successful in many ways. An effective working relationship among the Uzbekistan Customs Services, Uzbekistan Border Guards, and Uzbekistan Institute of Nuclear Physics has been developed. There has been unprecedented openness with the sharing of portal monitor data with Lawrence Livermore National Laboratory. The system has proved to be effective, with detection of illicit trafficking, and, at Alat, an arrest of three persons illegally transporting radioactive materials into Turkmenistan. The demonstration project has made Uzbekistan a model nonproliferation state in Central Asia and, with an expanded program, places them in a position to seal a likely transit route for illicit nuclear materials. These results will be described. In addition, this work is currently being expanded to include additional ports-of-entry in Uzbekistan. The process for deciding on which additional ports-of-entry to equip will also be described

    Full Text Available Grain storage is a vital component in the economy and the society. The quality and safety of grain storage are related to the hundreds of millions of people. In the process of grain storage, temperature and humidity are two major ecological factors that can affect the grain quality. Therefore, the parameters of temperature, humidity must be in accurate and real-time monitoring by supervisory systems in large granaries. The automatic monitoring of the grain storage will help us to improve the operation levels of grain storage, reduce the grain losses during stored procedure and reduce labor intensity. This project designs an environment monitoring system of the granary combining Embedded and ZigBee wireless sensor network technology. Using ZigBee wireless sensor network to complete acquisition and transmission of environment parameters and using ARM9 to achieve precise control of the barn environment as system data controller and using GSM to achieve the system's remote control, it greatly improves the flexibility and scalability of the warehouse management which sends available data to grain depot manager (Database management in time and filters invalid data on the spot. It makes many important aspects not need manager to complete on the scene, which saves a lot of manpower and material resources and improves labor productivity.

The electronic characteristic of the measurement system, allows him to accept different types of sensors (for the measurement of physical and chemical variables) and also digital communication. It is possible to run different mathematical models for the evaluation of the presence of pollutants, dispersion calculations, etc. The concentration of the treatment of the information, to expense of a given investment in communications is more convenient because it reduces the costs significantly in teams and operative. This way it can diminish the economic impact that takes place in the municipal and provincial governments the equipment acquisition for monitoring and environmental control. As concrete examples of this application in operation, the facilities of the cities of Cordoba and of Rio Tercero, province of Cordoba, can be mentioned. In the first one you can make the daily pursuit, in detailed and objective way, of the influence that the traffic urban produces in the atmosphere. In the second one it is possible to control the operation parameters of a station of industrial incineration and their correlation with the pollutants in chimney mouth

  20. Seismic countermeasures for environmental radiation monitoring system

    International Nuclear Information System (INIS)

    Environmental radiation monitoring system continually measures and monitors the amount of environmental radiation around nuclear facilities 24-hours a day, 365-days a year. These systems must continue to function even when a disaster occurs such as an earthquake. Fuji Electric takes countermeasures for earthquakes by duplicating transmissions lines with land ratio equipment and installing backup power supplies, seismically isolated monitoring posts, and seismically evaluated equipment. Furthermore, we have developed new portable monitoring posts equipped with semiconductor detectors and monitoring cars equipped with the same functions as stationary monitoring posts, and we can supply equipment that makes measuring and monitoring possible without power supplies or transmission lines.

    2004-10-13

    The deep hard rock drilling environment induces severe vibrations into the drillstring, which can cause reduced rates of penetration (ROP) and premature failure of the equipment. The only current means of controlling vibration under varying conditions is to change either the rotary speed or the weight-on-bit (WOB). These changes often reduce drilling efficiency. Conventional shock subs are useful in some situations, but often exacerbate the problems. The objective of this project is development of a unique system to monitor and control drilling vibrations in a ''smart'' drilling system. This system has two primary elements: (1) The first is an active vibration damper (AVD) to minimize harmful axial, lateral and torsional vibrations. The hardness of this damper will be continuously adjusted using a robust, fast-acting and reliable unique technology. (2) The second is a real-time system to monitor drillstring vibration, and related parameters. This monitor adjusts the damper according to local conditions. In some configurations, it may also send diagnostic information to the surface via real-time telemetry. The AVD is implemented in a configuration using magnetorheological (MR) fluid. By applying a current to the magnetic coils in the damper, the viscosity of the fluid can be changed rapidly, thereby altering the damping coefficient in response to the measured motion of the tool. Phase I of this program entailed modeling and design of the necessary subsystems and design, manufacture and test of a full laboratory prototype. Phase I of the project was completed by the revised end date of May 31, 2004. The objectives of this phase were met, and all prerequisites for Phase II have been completed. The month of June, 2004 was primarily occupied with the writing of the Phase I Final Report, the sole deliverable of Phase I, which will be submitted in the next quarter. Redesign of the laboratory prototype and design of the downhole (Phase II) prototype was begun.

  6. Interference Mitigation Techniques for Spectral Capacity Enhancement in GSM Networks

    Directory of Open Access Journals (Sweden)

    Ahmed M. Alaa

    2014-01-01

    Full Text Available Random Frequency Hopping (FH is a key feature of GSM networks that allows for capacity enhancement. The increased co-channel interference experienced in networks with tight frequency reuse schemes can be mitigated by adopting frequency hopping. Frequency hopping diversifies the interference signals over sparse transmitted bursts. This effect is called Interference Diversity. Interference Diversity allows the Forward Error Correcting codes (FEC to easily correct the corrupted bits. Thus, frequency hopping allows the network operator to use a tighter frequency reuse scheme without exhibiting higher levels of co-channel interference. Discontinuous Transmission (DTX is another interference mitigation method that utilizes the user’s silence frames to reduce the transmitted power, while Power Control (PC links the transmitted handset power with its relative distance from the Base Station (BTS. In this work, we study the impact of random FH, DTX and PC on the Spectral Capacity of GSM cellular networks by means of combined link level and system level simulation. It is shown that a spectral capacity gain is obtained in a 3/9 reuse scheme that deploys PC, DTX and FH compared to a conventional 4/12 reuse scheme.

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

    Directory of Open Access Journals (Sweden)

    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.

    Directory of Open Access Journals (Sweden)

    Himanshu D. Nayak

    2013-05-01

    Full Text Available General Packet Radio Service (GPRS [1], initiated in 1994, is an ETSI standard for packet data transmission using the core GSM (Global System for Mobile Communications radio access network. GPRS shares the GSM frequency bands with telephone and circuit-switched data traffic, and makes use of many properties of the physical layer of the original GSM system. Since radio resources of a cell are shared by both the GPRS and GSM voice services, how to efficiently allocate radio resources between these two services and at the same time not degrading the QOS of voice service is an important issue. Guard channels can be temporarily allocated to GPRS connections to improve channel utilization. As voice traffic load increases, the channels of some ongoing GPRS connections are de-allocated to arriving voice calls. The de-allocation must still maintain the minimum required QOS of the de-allocated connections. Simulation results show that at low voice traffic load, there is no need to apply admission control to GPRS connections. At high voice traffic load, the call admission control guarantees the blocking probability of new and handoff calls to be below certain value. But this will result in high GPRS rejection and low channel utilization. To guarantee the QOS of voice service not to be affected by the introduction of GPRS.

Today monitoring systems are either webcam based or simple motion detection based. Here we have interfaced both webcam and PIR sensor to the embedded system so that the user can get an immediate alert message and can take necessary steps. This system is based on the kernel of Cortex board with the GSM module being triggered by a Pyroelectric Infrared Sensor (PIR, which senses changes in the external temperature, especially in this case when an invader enters in to remote location and send SMS to the user. At the same time, by using a smart device or a PC, the user can link to the video streaming server constructed on the embedded board via the internet and browse the webpage to monitor the surveillance area, here the UVC driver and V4L programming is used to interface USB camera to the board to capture video information and then board will do two parallel works first one is transmits the processed captured video information using wireless network, which will be collected and monitored at client side using wireless network connection through the wireless device, second one is extracts the key frames from captured video using OpenCV and served on a server, the both provides an advantage to surveillance monitoring system.

  14. The Ames Power Monitoring System

    2003-01-01

    The Ames Power Monitoring System (APMS) is a centralized system of power meters, computer hardware, and specialpurpose software that collects and stores electrical power data by various facilities at Ames Research Center (ARC). This system is needed because of the large and varying nature of the overall ARC power demand, which has been observed to range from 20 to 200 MW. Large portions of peak demand can be attributed to only three wind tunnels (60, 180, and 100 MW, respectively). The APMS helps ARC avoid or minimize costly demand charges by enabling wind-tunnel operators, test engineers, and the power manager to monitor total demand for center in real time. These persons receive the information they need to manage and schedule energy-intensive research in advance and to adjust loads in real time to ensure that the overall maximum allowable demand is not exceeded. The APMS (see figure) includes a server computer running the Windows NT operating system and can, in principle, include an unlimited number of power meters and client computers. As configured at the time of reporting the information for this article, the APMS includes more than 40 power meters monitoring all the major research facilities, plus 15 Windows-based client personal computers that display real-time and historical data to users via graphical user interfaces (GUIs). The power meters and client computers communicate with the server using Transmission Control Protocol/Internet Protocol (TCP/IP) on Ethernet networks, variously, through dedicated fiber-optic cables or through the pre-existing ARC local-area network (ARCLAN). The APMS has enabled ARC to achieve significant savings ($1.2 million in 2001) in the cost of power and electric energy by helping personnel to maintain total demand below monthly allowable levels, to manage the overall power factor to avoid low power factor penalties, and to use historical system data to identify opportunities for additional energy savings. The APMS also provides power engineers and electricians with the information they need to plan modifications in advance and perform day-to-day maintenance of the ARC electric-power distribution system.

    The need to deploy large number of wireless devices, such as electricity or water meters, is becoming a key challenge for any utility. Furthermore, such a deployment should be functional for more than a decade. Many cellular operators consider LTE to be the single long term solution for wide area connectivity serving all types of wireless traffic. On the other hand, GSM is a well-adopted technology and represents a valuable asset to build M2M infrastructure due to the good coverage, device maturity, and low cost. In this paper we assess the potential of GSM/GPRS/EDGE to operate as a dedicated network for M2M communications. In order to enable M2M-dedicated operation in the near future, we reengineer the GSM/GPRS/EDGE protocol in a way that requires only minor software updates of the protocol stack. We propose different schemes to boost the number of M2M devices in the system without affecting the network stability. We show that a single GSM cell can support simultaneous low-data rate connections (e. g. to smart meters) in the order of 104 devices.

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

    International Nuclear Information System (INIS)

    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

    Practical guidelines for use in improving the monitoring of a photovoltaic (PV) system were presented. PV system monitoring often fails to meet desired objectives because of a lack of understanding of the importance of monitoring. These guidelines place emphasis on the planning and design of the monitoring system including setup, data storage, data analysis, with considerations for cold climates. Monitoring is usually carried out to determine one of three things: (1) system energy production, (2) more detailed engineering information, such as the performance of the various components of the system, or (3) more specific, research-oriented information such as the distribution of diffuse irradiance in the sky, or the spectral composition of light incident on the PV array. Twenty-three examples of variables that should be monitored to get basic information about the system`s energy production were presented. 10 refs.

    Full Text Available El estudio de factibilidad de implementación de una plataforma para servicios de valor agregado basados en la localización de teléfonos móviles, en una red de telefonía celular GSM, comienza con el análisis de los sistemas que permiten dicha localización. Dentro de estos sistemas se encuentran los S [...] istemas de Localización basados en la medición de la intensidad de la señal, que logran determinar la ubicación del móvil realizando un proceso de triangulación, estimando la distancia respecto a varias radiobases (al menos tres) a partir de la medición del nivel de la potencia que el móvil recibe de dichas radiobases. Analizando las posibilidades de obtener los niveles de potencia que recibe el móvil de las BTS circundantes, se concluye que existen dos maneras de implementar dicha plataforma a partir de la información del "Measurement Result Information Element": a) Monitoreando la capa 3 de la interfaz Abis entre la BTS y la BSC, o b) Solicitándolo al módulo SIM de los teléfonos GSM. Se explican con detalle, por cada una de estas posibilidades los esquemas de implementación y las condiciones que deben cumplirse con el fin de obtener el "Measurement Result Information Element". Finalmente se presentan las ventajas y desventajas que posee cada uno de estos métodos y se propone la realización de una prueba piloto en la ciudad de Caracas. Abstract in english Feasibility studies to implement a platform for Value Aggregated Services based on the localization of mobile telephones, in a cellular network GSM, begin with the analysis of the systems that allow such localization.

Such systems determine the location of a user carrying out a triangulation process that estimates the distance from several base stations (at least three), throughout the measurement of the power level that the user receives from these base stations. Analyzing the possibilities to obtain the levels of power that the cell phone receives from the surrounding BTS, we conclude that there are two approaches to implement this platform starting from the information of the Measurement Result Information Element: a) Monitoring layer 3 of the Abis interface, or b) Requesting it from the module SIM of the cell phone GSM. We explain in detail for each of these possibilities, the implementation outlines and the conditions that should be completed with the purpose to obtain the "Measurement Result Information Element". Finally, we present the advantages and disadvantages of each method and conclude with a recommendation for a test bed in the city of Caracas.

    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. This system's primary surface and subsurface operator consoles, for both supervisory and remote control activities, will be located in a Central Control Center (CCC) inside one of the surface facility buildings. The system consists of instrument and control equipment and components necessary to provide human operators with sufficient information to monitor and control the operation of the repository in an efficient and safe manner. The system consists of operator consoles and workstations, multiple video display terminals, communications and interfacing equipment, and instrument and control software with customized configuration to meet the needs of the Monitored Geologic Repository (MGR). Process and logic controllers and the associated input/output units of each system interfaced with this system will be configured into Remote Terminal Units (RTU) and located close to the systems to be monitored and controlled. The RTUs are configured to remain operational should communication with CCC operations be lost. The system provides closed circuit television to selectively view systems, operations, and equipment areas and to aid in the operation of mechanical systems. Control and monitoring of site utility systems will be located in the CCC. Site utilities include heating, ventilation, and air conditioning equipment; plant compressed air; plant water; firewater; electrical systems; and inert gases, such as nitrogen, if required. This system interfaces with surface and subsurface systems that either generate output data or require remote control input. The system interfaces with the Site Communications System for bulk storage of operational data, on-site and off-site communication, and a plant-wide public announcement system. The system interfaces with the Safeguards and Security System to provide operational status and emergency alarm indications. The system interfaces with the Site Operation System to provide site wide acquisition of data for analysis and reports, historical information for trends, utility information for plant operation, and to receive operating plans and procedures.

  18. Centralized environmental radiation monitoring system in JAERI

    International Nuclear Information System (INIS)

    Japan Atomic Energy Research Institute (JAERI) has continued the radiation background survey and environmental radiation monitoring to ensure the safety of the residents around the Institute. For the monitoring of ? and ? radiations and ? and ? radioactivities in air, the centralized automatic environmental radiation monitoring system (EMS) applying a computer with monitoring stations (MS) was established. The system has been renewed twice in 1973 and 1988. In 1962, a new concept emergency environmental ?-ray monitoring system (MP) was begun to construct and completed in 1965 independent of EMS. The first renewal of the EMS was carried out by focusing on the rapid and synthetic judgement and estimation of the environmental impacts caused by radiation and radioactive materials due to the operation of nuclear facilities by centralizing the data measured at MS, MP, a meteorological station, stack monitors and drainage monitoring stations under the control of computer. Present system renewed in 1988 was designed to prevent the interruption of monitoring due to computer troubles, communication troubles and power failures especially an instant voltage drop caused by thunder by reflecting the experiences through the operation and maintenance of the former system. Dual telemeters whose power is constantly supplied via batteries (capable of 10 min. monitoring after power failure) are equipped in the monitoring center to cope with telemeter troubles, which has operated successfully without any suspension being attributable to the power failures and telemeter troubles.

  19. Lower Saxony's feeder monitoring system - radioactivity

    International Nuclear Information System (INIS)

    The results obtained from the measuring programmes under Lower Saxony's feeder monitoring system - radioactivity with regard to the media concerning water are summed up, evaluated and made available to the respective competent authorities and to the interested public. Radiological feeder monitoring is a special feature because both immission and effluents are monitored. In the 'Guideline on effluent and immission monitoring of nuclear facilities' measuring programmes are given which are carried out by operators and independent measuring centres. Such systematic monitoring of immissions and effluents is not done for any other technical plant. Depending on the task, different monitoring concepts are used both for immission and effluent monitoring. Within the framework of immission monitoring the impacts of feed-ins are recorded and documented. Radioactive effluents cause immission and thus have an impact on plant, animal and man. (orig.)

    2003-06-01

    Many parties have already demonstrated telemedicine applications that use cellular phones and the Internet. A current trend in telecommunication is the convergence of wireless communication and computer network technologies, and the emergence of wireless application protocol (WAP) devices is an example. Since WAP will also be a common feature found in future mobile communication devices, it is worthwhile to investigate its use in telemedicine. This paper describes the implementation and experiences with a WAP-based telemedicine system for patient-monitoring that has been developed in our laboratory. It utilizes WAP devices as mobile access terminals for general inquiry and patient-monitoring services. Authorized users can browse the patients' general data, monitored blood pressure (BP), and electrocardiogram (ECG) on WAP devices in store-and-forward mode. The applications, written in wireless markup language (WML), WMLScript, and Perl, resided in a content server. A MySQL relational database system was set up to store the BP readings, ECG data, patient records, clinic and hospital information, and doctors' appointments with patients. A wireless ECG subsystem was built for recording ambulatory ECG in an indoor environment and for storing ECG data into the database. For testing, a WAP phone compliant with WAP 1.1 was used at GSM 1800 MHz by circuit-switched data (CSD) to connect to the content server through a WAP gateway, which was provided by a mobile phone service provider in Hong Kong. Data were successfully retrieved from the database and displayed on the WAP phone. The system shows how WAP can be feasible in remote patient-monitoring and patient data retrieval. PMID:12834165

  6. DOWNHOLE VIBRATION MONITORING & CONTROL SYSTEM

    2005-04-27

    The objective of this program is to develop a system to both monitor the vibration of a bottomhole assembly, and to adjust the properties of an active damper in response to these measured vibrations. Phase I of this program, which entailed modeling and design of the necessary subsystems and design, manufacture and test of a full laboratory prototype, was completed on May 31, 2004. The principal objectives of Phase II are: more extensive laboratory testing, including the evaluation of different feedback algorithms for control of the damper; design and manufacture of a field prototype system; and, testing of the field prototype in drilling laboratories and test wells. As a result of the lower than expected performance of the MR damper noted last quarter, several additional tests were conducted. These dealt with possible causes of the lack of dynamic range observed in the testing: additional damping from the oil in the Belleville springs; changes in properties of the MR fluid; and, residual magnetization of the valve components. Of these, only the last was found to be significant. By using a laboratory demagnetization apparatus between runs, a dynamic range of 10:1 was achieved for the damper, more than adequate to produce the needed improvements in drilling. Additional modeling was also performed to identify a method of increasing the magnetic field in the damper. As a result of the above, several changes were made in the design. Additional circuitry was added to demagnetize the valve as the field is lowered. The valve was located to above the Belleville springs to reduce the load placed upon it and offer a greater range of materials for its construction. In addition, to further increase the field strength, the coils were relocated from the mandrel to the outer housing. At the end of the quarter, the redesign was complete and new parts were on order. The project is approximately three months behind schedule at this time.

    Presently work the methodology used by the Laboratory of Thermoluminescent Dosimetry (TLD) of the Nuclear Regulatory Authority (RNA) to gauge it system of environmental monitoring in function of the media absorbed dose rate in free air and the environmental dose equivalent, H*(10), according to the recommendation ICRU Report 47 is described. It was studied the response of the environmental dosemeter (DA) in fields of photonic radiation of energies W60, Wl 10, W200 and 137 Cs. The irradiations were carried out following the recommendations of the standard ISO:4037. It was analyzed the response in the DA of the detectors LiF: Mg, Ti and CaF2: Dy for the different radiation qualities and the relative response at 137 Cs of both. The methodology used in the evaluation of the dose includes: the correction of the readings of both detectors by fading, gotten experimentally, the witness of transfers, the energy answer and the value of the zero. The dose is calculated applying the average pondered in uncertainty of the dose obtained for each type of detector. Its were analyzed and calculated the uncertainties that affect to the measurement following the recommendation of the Argentine standard IRAM 35050. The detection limit of the absorbed dose rate in free air of this system it is 3.5 n Gy/h for a period of sampling of 3 months. With this detection limit environmental dose equivalent rates of the order of 70 n Sv/h are measured with an expanded uncertainty of the order of 10% with a cover factor k = 2. (Author)

    2013-04-01

    Full Text Available In the past pace of life it is difficult for people to be constantly available for their near ones who might need them while they are suffering from any disease or physical disorder. So constant monitoring of the patient’s body parameters such as body temperature, Pulse rate and sugar level etc becomes difficult. Generally in ICUs nurses are taking care of abnormalities n the health of the patient but they may not be available for taking care of patient’s health 24X7. So sometimes in absence of care taker it may happens that the health of the patient becomes abnormal /critical from normal condition. So to remove these critical conditions we have proposed an automatic low cost microcontroller & intelligent Wireless GSM based Advanced patient monitoring system which continuously in the regular interval of time (DS1307 RTC for clock measuring the intensive parameter of the patient’s health and if any abnormal condition occurs, it directly give a message to the doctor’s cell phone that particular word no’s particular parameter is out of the range. Due to this alert message, Doctor can do the fast assessment of the patient’s health without wasting the time.

  11. Supervisory monitoring system in nuclear power plants

    International Nuclear Information System (INIS)

    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.

  12. Storage monitoring systems for the year 2000

    International Nuclear Information System (INIS)

    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

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

    International Nuclear Information System (INIS)

    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)

    The LHCb ECAL is a shashlik calorimeter of 6016 cells, covering 7.68 x 6.24 m$^2$ area. To monitor the readout chain of each ECAL cell, the LHCb ECAL is equipped with a LED based monitoring system. During the LHC Run I (2009-2012) it was found that the precision of the monitoring suffers from the radiation degradation of transparency of polystyrene clear fibers used to transport the LED light to the ECAL photomultipliers. In order to improve the performance of the monitoring system, and especially in view of significant increase of LHCb working luminosity foreseen after 2018, the present plastic fibers have been replaced by radiation hard quartzfi bers. The performance of the old LHCb ECAL monitoring system during LHC Run I and the design of the upgraded system are discussed here.

  19. A novel security algorithm for gsm mobile

    International Nuclear Information System (INIS)

    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.

    Full Text Available Home security is very popular in present days in its simplest form home controlling is the ability to control lighting , household and image reorganization appliances remotely with this device automation safety from theft, leak in of raw gas and fire is also the most important requirement of home for people by combining wireless sensor net work and GSM technology, In this proposes a new solution for remote home security and device control system. The system is composed of the ARM7 based WSN center node with GSM module, data collecting node , device control node and mobile phone. The WSN data collecting node module is connected with PIR, temperature sensor, smoke detector and gas sensor separately and send data to the data collecting node. Advances in the field of Information Technology also make Information Security an inseparable part of it. In order to deal with security, Authentication plays an important role. This paper presents a review on the Voice authentication techniques and somefuture possibilities in this field. In Voice & face, a human being needs to be identified based on some characteristic physiological parameters. A wide variety of systems require reliable personal recognition schemes to either confirm or determine the identity of an individual requesting their services.The purpose of such schemes is to ensure that the rendered services are accessed only by a legitimate user, and not anyone else. By using Voice & ace it is possible to confirm or establish an individual’s identity. The position of biometrics in the current field of Security has been depicted in this work. We have also outlined options about the usability of voice and face authentication systems. The data collecting node will send encoded alarm signal to the WSN center node through WSN sensor network established in home . Once the WSN center node receives alarm signal, it will send alarm SMS to the users through the GSM module and GSM network immediately.

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

    International Nuclear Information System (INIS)

    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 ?Gy h-1 and can detect 7.4 MBq (200 ?Ci) of 60Co and 25 MBq (675 ?Ci) 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 at nodal Emergency Response Centre (ERC) which enhances the quick decision making capability on the implementation of counter measures, whenever required.This paper discusses the selection and optimization of the monitoring systems required during any radiological emergencies, monitoring methodology to be adopted and the results of the monitoring exercises carried out at various cities of India i.e., Jaipur, Bangalore, Thiruvanathapuram, Nagpur, Hyderabad, Tarapur etc. The mobile monitoring methodology adopted and base line dose rate data generated for the major cities will be very useful during the assessment of impact, if required, during any radiological emergency scenario in the cities.

    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.

    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%

    2012-01-01

    SystemC is a modeling language built as an extension of C++. Its growing popularity and the increasing complexity of designs have motivated research efforts aimed at the verification of SystemC models using assertion-based verification (ABV), where the designer asserts properties that capture the design intent in a formal language such as PSL or SVA. The model then can be verified against the properties using runtime or formal verification techniques. In this paper we focus on automated generation of runtime monitors from temporal properties. Our focus is on minimizing runtime overhead, rather than monitor size or monitor-generation time. We identify four issues in monitor generation: state minimization, alphabet representation, alphabet minimization, and monitor encoding. We conduct extensive experimentation and identify a combination of settings that offers the best performance in terms of runtime overhead.

    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.

    In Managed Aquifer Recharge (MAR) schemes the monitoring system, for both water quality and quantity issues, plays a key role in assuring that a groundwater recharge plant is really managed. Considering induced Riverbank Filtration (RBF) schemes, while the effect of the augmented filtration consists in an improvement of the quality and quantity of the water infiltrating the aquifer, there is in turn the risk for groundwater contamination, as surface water bodies are highly susceptible to contamination. Within the framework of the MARSOL (2014) EU FPVII-ENV-2013 project, an experimental monitoring system has been designed and will be set in place at the Sant'Alessio RBF well field (Lucca, Italy) to demonstrate the sustainability and the benefits of managing induced RBF versus the unmanaged option. The RBF scheme in Sant'Alessio (Borsi et al. 2014) allows abstraction of an overall amount of about 0,5 m3/s groundwater providing drinking water for about 300000 people of the coastal Tuscany. Water is derived by ten vertical wells set along the Serchio River embankments inducing river water filtration into a high yield (10-2m2/s transmissivity) sand and gravel aquifer. Prior to the monitoring system design, a detailed site characterization has been completed taking advantage of previous and new investigations, the latter performed by means of MOSAIC on-site investigation platform (UFZ). A monitoring network has been set in place in the well field area using existing wells. There groundwater head and the main physico-chemical parameters (temperature, pH, dissolved oxygen, electrical conductivity and redox potential) are routinely monitored. Major geochemical compounds along with a large set of emerging pollutants are analysed (in cooperation with IWW Zentrum Wasser, Germany) both in surface-water and ground-water. The experimental monitoring system (including sensors in surface- and ground-water) has been designed focusing on managing abstraction efficiency and safety at one of the ten productive wells. The groundwater monitoring system consists of a set of six piezometer clusters drilled around a reference well along the main groundwater flowpaths. At each cluster, three piezometers (screened in the penultimate meter) are set at different depths to allow multilevel monitoring and sampling. At six selected piezometers, depending on ongoing hydrogeochemical investigations, six sensors for continuous monitoring of groundwater head, temperature and electrical conductivity will be set in operation. Within the Serchio River, two monitoring stations will be set in operation in order to monitor river head, water temperature and electrical conductivity upstream and downstream the experimental plot. A multi/parameter probe for the detection of selected analytes such nitrates, and selected organics to be defined will also be set in the Serchio River water. Each sensor will constitute a node of a Wireless Sensor Network (WSN). The WSN is based on several data loggers «client» connected via radio to one server point (Gateway), transmitting to a server via GSM-GPRS. This set up, while maintaining the high quality of data transmission, will allow to reduce installation and operational costs. The main characteristic of the conceived monitoring system is that sensors have been selected so to transmit data in an open format. The sensor network prototype will allow to get a substantial sensor cost reduction compared to available commercial solutions. The ultimate goal of this complex monitoring setting will be that of defining the minimum monitoring set up to guarantee efficiency and safety of groundwater withdrawals.

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

    The CMS data acquisition system comprises O(20000) interdependent services that need to be monitored in near real-time. The ability to monitor a large number of distributed applications accurately and effectively is of paramount importance for robust operations. Application monitoring entails the collection of a large number of simple and composed values made available by the software components and hardware devices. A key aspect is that detection of deviations from a specified behaviour is supported in a timely manner, which is a prerequisite in order to take corrective actions efficiently. Given the size and time constraints of the CMS data acquisition system, efficient application monitoring is an interesting research problem. We propose an approach that uses the emerging paradigm of Web-service based eventing systems in combination with hierarchical data collection and load balancing. Scalability and efficiency are achieved by a decentralized architecture, splitting up data collections into regions of col...

    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.

  6. Underground ventilation remote monitoring and control system

    International Nuclear Information System (INIS)

    This paper presents the design and installation of an underground ventilation remote monitoring and control system at the Waste Isolation Pilot Plant. This facility is designed to demonstrate safe underground disposal of U.S. defense generated transuranic nuclear waste. To improve the operability of the ventilation system, an underground remote monitoring and control system was designed and installed. The system consists of 15 air velocity sensors and 8 differential pressure sensors strategically located throughout the underground facility providing real-time data regarding the status of the ventilation system. In addition, a control system was installed on the main underground air regulators. The regulator control system gives indication of the regulator position and can be controlled either locally or remotely. The sensor output is displayed locally and at a central surface location through the site-wide Central Monitoring System (CMS). The CMS operator can review all sensor data and can remotely operate the main underground regulators. Furthermore, the Virtual Address Extension (VAX) network allows the ventilation engineer to retrieve real-time ventilation data on his personal computer located in his workstation. This paper describes the types of sensors selected, the installation of the instrumentation, and the initial operation of the remote monitoring system

    International Nuclear Information System (INIS)

    Neutron detectors are commonly used by the nuclear materials processing industry to monitor fissile materials in process vessels and tanks. The proper functioning of these neutron monitors must be periodically evaluated. We have developed and placed in routine use a PC-based multichannel analyzer (MCA) system for on-line BF3 and He-3 gas-filled detector function testing. The automated system: 1) acquires spectral data from the monitor system, 2) analyzes the spectrum to determine the detector's functionality, 3) makes suggestions for maintenance or repair, as required, and 4) saves the spectrum and results to disk for review. The operator interface has been designed to be user-friendly and to minimize the training requirements of the user. The system may also be easily customized for various applications

    2008-01-01

    All calorimeter sub-detectors in LHCb, the Scintillator Pad Detector (SPD), the Preshower detector (PS), the Electromagnetic Calorimeter (ECAL) and the Hadron Calorimeter (HCAL) are equipped with the Hamamatsu photomultiplier tubes (PMT) as devices for light to electrical signal conversion [1]. The PMT gain behaviour is not stable in a time, due to changes in the load current and due to ageing. The calorimeter light emitting diode (LED) monitoring system has been developed to monitor the PMT gain over time during data taking. Furthermore the system will play an important role during the detector commissioning and during LHC machine stops, in order to perform tests of the PMTs, cables and FE boards and measurements of relative time alignment. The aim of the paper is to describe the LED monitoring system architecture, some technical details of the electronics implementation based on radiation tolerant components and to summarize the system performance.

    1996-11-01

    The Connecticut Department of Transportation (ConnDOT) has undertaken a major initiative to install permanent remotely- accessible monitoring systems on seven in-service highway bridges. These systems will consist of either a Roadway Weather Information System (RWIS), or Structural Monitoring System (SMS), or both, depending on the structure type and/or location. The RWIS provides weather related information regarding the pavement on and off the structure and ambient weather conditions at the bridge site. Systems like this are commercially available and in use throughout the country assisting transportation agencies in performing winter maintenance operations. The SMS is the product of cooperative research at the University of Connecticut and ConnDOT. The University has specified, installed and operated a prototype vibrational-based monitoring system on tow in-service bridges during separate year-long studies. The planned SMS, modeled after the prototype, includes accommodations for a variety of sensors including strain, tilt, structural temperature and vibration. The ultimate goal of this work is to develop a generic platform for a remote bridge monitoring system which can be adapted to any bridge with any combination of sensors and sensor types. Such a system would benefit both the safety and management of these structures. Current activity along with background information are discussed.

    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

    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.

  18. Data-acquisition system for radon monitoring

    International Nuclear Information System (INIS)

    A data-acquisition system was designed by the Bureau of Mines to monitor five detectors with radon continuously flowing through each. These detectors could be monitored up to 12 times an hour, but were only monitored according to a preset time, thus allowing radon to be monitored continuously in a uranium mine. The counter can be set to monitor each detector for any period of time up to 16.5 minutes. This allows very low concentrations to be monitored longer to reduce statistical error. There would be no upper limit in radon concentration that could be monitored, but there would be a lower limit of 50 pCi/l. Each detector was calibrated by the Lucas flask method. Multiple samples were taken at two different concentrations, and the correction factor for each detector was determined by a least squares fit of the data. To verify the calibrations, a series of measurements at several concentrations were made against a constant source. The agreement at low radon concentrations (300 pCi/l) with the two-filter method was within 3 percent; thus, the total error would be this difference plus the two-filter error. At high concentrations, the coefficient of variation ranged between 2.1 and 9.8 percent for the five different detector units

    Full Text Available Large organizations always require fast and efficient network monitoring system which reports to the network administrator as soon as a network problem arises. This paper presents an effective and automatic network monitoring system that continuously monitor all the network switches and inform the administrator by email or sms when any of the network switch goes down. This system also point out problem location in the network topology and its effect on the rest of the network. Such network monitoring system uses smart interaction of Request Tracker (RT and Nagios softwares in linux environment. The network topology is built in Nagios which continuously monitor all of the network nodes based on the services defined for them. Nagios generates a notification as soon as a network node goes down and sends it to the RT software. This notification will generate a ticket in RT database with problematic node information and its effect on the rest of the network. The RT software is configured to send the ticket by email and sms to the network administrator as soon as it is created. If the administrator is busy at the moment and does not resolve the ticket within an hour, the same ticket is automatically sent to the second network responsible person depending upon the priority defined. Thus, all persons in the priority list are informed one by one until the ticket is resolved.

  1. 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 ...

  2. Reactivity monitoring in ADS systems

    International Nuclear Information System (INIS)

    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)

    2013-01-01

    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.

    The number of Renewable Energy (RE) systems increases due to the low carbon energy policy in most of industrialised countries. In order to ensure the performance of RE sustainable and reduce maintenance costs, remote monitoring systems of RE plant condition and performance are essential. Wireless monitoring systems are easy to install and operate, but requires high cost in general. Radio Frequency technology is relatively cheap, but its transmission range is limited. It is a challenge to establish long range communication between RE plants and the monitoring centre in cost effective way. In this paper, a novel remote condition monitoring system for RE systems is presented, which exploits RF modems in the multi-point link network to make long range communication. The paper illustrates the overview of the proposed system and the results of the field tests implemented with PV+Wind and PV+Wave hybrid power generation systems at land and sea.

    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.

With the help of BCM system, the bunch current in each bucket can be monitored in the Central Control Room. The BEPCII timing system can also use the bunch current database to decide which bucket needs to refill to implement ``top-off'' injection.

  9. A high reliability oxygen deficiency monitoring system

    International Nuclear Information System (INIS)

    The escalating use of cryogens at national laboratories in general and accelerators in particular, along with the increased emphasis placed on personnel safety, mandates the development and installation of oxygen monitoring systems to insure personnel safety in the event of a cryogenic leak. Numerous vendors offer oxygen deficiency monitoring systems but fail to provide important features and/or flexibility. This paper describes a unique oxygen monitoring system developed for the Magnet Test Laboratory (MTL) at the Superconducting Super Collider Laboratory (SSCL). Features include: high reliability, oxygen cell redundancy, sensor longevity, simple calibration, multiple trip points, offending sensor audio and visual indication, global alarms for building evacuation, local and remote analog readout, event and analog data logging, EMAIL event notification, phone line voice status system, and multi-drop communications network capability for reduced cable runs. Of particular importance is the distributed topology of the system which allows it to operate in a stand-alone configuration or to communicate with a host computer. This flexibility makes it ideal for small applications such as a small room containing a cryogenic dewar, as well as larger systems which monitor many offices and labs in several buildings

  18. Gauging Systems Monitor Cryogenic Liquids

    Science.gov (United States)

    2009-01-01

    Rocket fuel needs to stay cool - super cool, in fact. The ability to store gas propellants like liquid hydrogen and oxygen at cryogenic temperatures (below -243 F) is crucial for space missions in order to reduce their volumes and allow their storage in smaller (and therefore, less costly) tanks. The Agency has used these cryogenic fluids for vehicle propellants, reactants, and life support systems since 1962 with the Centaur upper stage rocket, which was powered with liquid oxygen and liquid hydrogen. During proposed long-duration missions, super-cooled fluids will also be used in space power systems, spaceports, and lunar habitation systems. In the next generation of launch vehicles, gaseous propellants will be cooled to and stored for extended periods at even colder temperatures than currently employed via a process called densification. Densification sub-cools liquids to temperatures even closer to absolute zero (-459 F), increasing the fluid s density and shrinking its volume beyond common cryogenics. Sub-cooling cryogenic liquid hydrogen, for instance, from 20 K (-423 F) to 15 K (-432.4 F) reduces its mass by 10 percent. These densified liquid gases can provide more cost savings from reduced payload volume. In order to benefit from this cost savings, the Agency is working with private industry to prevent evaporation, leakage, and other inadvertent loss of liquids and gases in payloads - requiring new cryogenic systems to prevent 98 percent (or more) of boil-off loss. Boil-off occurs when cryogenic or densified liquids evaporate, and is a concern during launch pad holds. Accurate sensing of propellants aboard space vehicles is also critical for proper engine shutdown and re-ignition after launch, and zero boil-off fuel systems are also in development for the Altair lunar lander.

  19. Background compensation methodologies for contamination monitoring systems

    International Nuclear Information System (INIS)

    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. Evaluation of a multiport groundwater monitoring system

    International Nuclear Information System (INIS)

    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

  3. Uranium concentration monitor manual: 2300 system

    International Nuclear Information System (INIS)

    This manual describes the design, operation, and procedures for measurement control for the automated uranium concentration monitor on the 2300 solvent extraction system at the Oak Ridge Y-12 Plant. The nonintrusive monitor provides a near-real time readout of uranium concentration at two locations simultaneously in the solvent extraction system for process monitoring and control. Detectors installed at the top of the extraction column and at the bottom of the backwash column acquire spectra of gamma rays from the solvent extraction solutions in the columns. Pulse-height analysis of these spectra gives the concentration of uranium in the organic product of the extraction column and in the aqueous product of the solvent extraction system. The visual readouts of concentrations for process monitoring are updated every 2 min for both detection systems. Simultaneously, the concentration results are shipped to a remote computer that has been installed by Y-12 to demonstrate automatic control of the solvent extraction system based on input of near-real time process operation information. 8 refs., 13 figs., 4 tabs

    International Nuclear Information System (INIS)

    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

    2011-04-01

    Sleep plays the important role of rejuvenating the body, especially the central nervous system. However, more than thirty million people suffer from sleep disorders and sleep deprivation. That can cause serious health consequences by increasing the risk of hypertension, diabetes, heart attack and so on. Apart from the physical health risk, sleep disorders can lead to social problems when sleep disorders are not diagnosed and treated. Currently, sleep disorders are diagnosed through sleep study in a sleep laboratory overnight. This involves large expenses in addition to the inconvenience of overnight hospitalization and disruption of daily life activities. Although some systems provide home based diagnosis, most of systems record the sleep data in a memory card, the patient has to face the inconvenience of sending the memory card to a doctor for diagnosis. To solve the problem, we propose a wireless sensor system for sleep apnea, which enables remote monitoring while the patient is at home. The system has 5 channels to measure ECG, Nasal airflow, body position, abdominal/chest efforts and oxygen saturation. A wireless transmitter unit transmits signals with Zigbee and a receiver unit which has two RF modules, Zigbee and Wi-Fi, receives signals from the transmitter unit and retransmits signals to the remote monitoring system with Zigbee and Wi-Fi, respectively. By using both Zigbee and Wi-Fi, the wireless sensor system can achieve a low power consumption and wide range coverage. The system's features are presented, as well as continuous monitoring results of vital signals.

  7. The Anatahan volcano-monitoring system

    2003-12-01

    A real-time 24/7 Anatahan volcano-monitoring and eruption detection system is now operational. There had been no real-time seismic monitoring on Anatahan during the May 10, 2003 eruption because the single telemetered seismic station on Anatahan Island had failed. On May 25, staff from the Emergency Management Office (EMO) of the Commonwealth of the Northern Mariana Islands and the U. S. Geological Survey (USGS) established a replacement telemetered seismic station on Anatahan whose data were recorded on a drum recorder at the EMO on Saipan, 130 km to the south by June 5. In late June EMO and USGS staff installed a Glowworm seismic data acquisition system (Marso et al, 2003) at EMO and hardened the Anatahan telemetry links. The Glowworm system collects the telemetered seismic data from Anatahan and Saipan, places graphical display products on a webpage, and exports the seismic waveform data in real time to Glowworm systems at Hawaii Volcano Observatory and Cascades Volcano Observatory (CVO). In early July, a back-up telemetered seismic station was placed on Sarigan Island 40 km north of Anatahan, transmitting directly to the EMO on Saipan. Because there is currently no population on the island, at this time the principal hazard presented by Anatahan volcano would be air traffic disruption caused by possible erupted ash. The aircraft/ash hazard requires a monitoring program that focuses on eruption detection. The USGS currently provides 24/7 monitoring of Anatahan with a rotational seismic duty officer who carries a Pocket PC-cell phone combination that receives SMS text messages from the CVO Glowworm system when it detects large seismic signals. Upon receiving an SMS text message notification from the CVO Glowworm, the seismic duty officer can use the Pocket PC - cell phone to view a graphic of the seismic traces on the EMO Glowworm's webpage to determine if the seismic signal is eruption related. There have been no further eruptions since the monitoring system was installed, but regional tectonic earthquakes have provided frequent tests of the system. Reliance on a Pocket PC - cell phone requires that the seismic duty officer remain in an area with cell phone coverage. With this monitoring method, the USGS is able to provide rapid notice of an Anatahan eruption to the EMO and the Washington Volcano Ash Advisory Center.

    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.

  3. Smart actuators: Valve Health Monitor (VHM) system

    Science.gov (United States)

    Perotti, José; Lucena, Angel; Burns, Bradley

    2006-05-01

    The health of electromechanical systems (actuators) and specifically of solenoid valves is a primary concern at Kennedy Space Center (KSC). These systems control the storage and transfer of such commodities as liquid hydrogen. The potential for the failure of electromechanical systems to delay a scheduled launch or to cause personnel injury requires continual maintenance and testing of the systems to ensure their readiness. Monitoring devices need to be incorporated into these systems to verify the health and performance of the valves during real operating conditions. It is very advantageous to detect degradation and/or potential problems before they happen. This feature will not only provide safer operation but save the cost of unnecessary maintenance and inspections. Solenoid valve status indicators are often based upon microswitches that work by physically contacting a valve's poppet assembly. All of the physical contact and movement tends to be very unreliable and is subject to wear and tear of the assemblies, friction, breakage of the switch, and even leakage of the fluid (gas or liquid) in the valve. The NASA Instrumentation Branch, together with its contractor, ASRC Aerospace, has developed a solenoid valve smart current signature sensor that monitors valves in a noninvasive mode. The smart system monitors specific electrical parameters of the solenoid valves and detects and predicts the performance and health of the device. The information obtained from the electrical signatures of these valves points to not only electrical components failures in the valves but also mechanical failures and/or degradations.

  5. Replaceable Sensor System for Bioreactor Monitoring

    Science.gov (United States)

    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.

    A system for monitoring moving objects, such as the flight of honeybees and other insects, using a pulsed laser light source. This system has a self-powered micro-miniaturized transmitting unit powered, in the preferred embodiment, with an array solar cells. This transmitting unit is attached to the object to be monitored. These solar cells provide current to a storage energy capacitor to produce, for example, five volts for the operation of the transmitter. In the simplest embodiment, the voltage on the capacitor operates a pulse generator to provide a pulsed energizing signal to one or more very small laser diodes. The pulsed light is then received at a receiving base station using substantially standard means which converts the light to an electrical signal for processing in a microprocessor to create the information as to the movement of the object. In the case of a unit for monitoring honeybees and other insects, the transmitting unit weighs less than 50 mg, and has a size no larger than 1.times.3.times.5 millimeters. Also, the preferred embodiment provides for the coding of the light to uniquely identify the particular transmitting unit that is being monitored. A "wake-up" circuit is provided in the preferred embodiment whereby there is no transmission until the voltage on the capacitor has exceeded a pre-set threshold. Various other uses of the motion-detection system are described.

    A more efficient newer algorithm of detecting systolic and diastolic pressure of human body along with a complete package of an effective user-friendly embedded programmable blood pressure monitoring system has been proposed in this paper to reduce the overall workload of medical personals as well as to monitor patient's condition more conveniently and accurately. Available devices for measuring blood pressure have some problems and limitations in case of both analog and digital devices. The sphygmomanometer, being analog device, is still being used widely because of its reliability and accuracy over digital ones. But it requires a skilled person to measure the blood pressure and obviously not being automated as well as time consuming. Our proposed system being a microcontroller based embedded system has the advantages of the available digital blood pressure machines along with a much improved form and has higher accuracy at the same time. This system can also be interfaced with computer through serial port/USB to publish the measured blood pressure data on the LAN or internet. The device can be programmed to determine the patient's blood pressure after each certain interval of time in a graphical form. To sense the pressure of human body, a pressure to voltage transducer is used along with a cuff in our system. During the blood pressure measurement cycle, the output voltage of the transducer is taken by the built-in ADC of microcontroller after an amplifier stage. The recorded data are then processed and analyzed using the effective software routine to determine the blood pressure of the person under test. Our proposed system is thus expected to certainly enhance the existing blood pressure monitoring system by providing accuracy, time efficiency, user-friendliness and at last but not the least the 'better way of monitoring patient's blood pressure under critical care' all together at the same time.

  9. Corrosion Rate Monitoring in District Heating Systems

    DEFF Research Database (Denmark)

    Hilbert, Lisbeth Rischel; Nielsen, Lars Vendelbo

    2005-01-01

    Quality control in district heating systems to keep uniform corrosion rates low and localized corrosion minimal is based on water quality control. Side-stream units equipped with carbon steel probes for online monitoring were mounted in district heating plants to investigate which techniques would be applicable, and if on-line monitoring could improve the quality control. Water quality monitoring was applied as well as corrosion rate monitoring with linear polarization resistance (LPR), electrochemical impedance spectroscopy (EIS), electrical resistance (ER) technique, mass loss and a crevice corrosion cell for localized corrosion risk estimation. Important variations in corrosion rate due to changes in make-up water quality were detected with the continuous monitoring provided by ER and crevice cell, while LPR gave unreliable corrosion rates. The acquisition time of two-three days for EIS measurements was too long for real time data, and reliable mass loss data could only be obtained after 6 months exposure.It was furthermore found that localized corrosion events detected by the carbon steel crevice corrosion cell correlated with oxygen peaks of even a few hours duration.

    Full Text Available The system of environmental radiation monitoring established in Spain is composed of several networks with different objectives, a monitoring network in the vicinity of the facilities and several national networks financed and managed by public agencies. The operators of the facilities are responsible for the conduct of its Environmental Radiological Surveillance Program as directed by the CSN. Moreover, the Directorate General of Civil Defense and Emergencies has a Radioactivity Warning Network (RAR consisting of over 900 automatic stations measuring dose rate distributed nationwide. The Environmental Radioactivity Monitoring Network (Revira, managed by the CSN, is a nationwide network, consists of a Network of Sampling Stations (REM and a Network of Automatic Stations for continuous monitoring (REA. The autonomous communities of Valencia, Catalonia, Extremadura and the Basque Country have their own automated networks similar to that of the CSN. Revira provides information on the radioactivity in the air, soil, water (drinking, inland and sea and of food. The sampling and analysis programs are tailored to radiological recommendations laid down in the European Union Commission. The REM has the collaboration of laboratories in universities and the Centre for Energy, Environmental and Technological Research (CIEMAT for execution. The monitoring of inland and coastal waters is undertaken by the Centre for Studies and Experimentation of Public Works, Ministry of Public Works (CEDEX.

    To accelerate both protons and heavy ions, the AGS Booster requires a broadband (multi-octave) beam position monitoring system with a dynamic range spanning several orders of magnitude (2 {times} 10{sup 10} to 1.5 {times} 10{sup 13} particles per pulse). System requirements include the ability to acquire single turn trajectory and average orbit information with {plus minus} 0.1 mm resolution. The design goal of {plus minus} 0.5 mm corrected accuracy requires that the detectors have repeatable linear performance after periodic bakeout at 300 {degree}C. The system design and capabilities of the Booster Beam Position Monitor will be described, and initial results presented. 7 refs., 5 figs.

  12. A Resilient Condition Assessment Monitoring System

    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.

  13. A design methodology for unattended monitoring systems

    Energy Technology Data Exchange (ETDEWEB)

    SMITH,JAMES D.; DELAND,SHARON M.

    2000-03-01

    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.

    Full Text Available Concern about human exposure to radiofrequency (RF is not new. The conveniences and satisfaction derived in the use of GSM mobile phone is being threatened by claims of adverse effects on human health by radiation coming from this device. This radiation belongs to the type called non-ionizing radiation the health hazard of which remains debatable. Research has not been carried out on possible effect this device might have on human health and no experimental proof, based on data obtained within Nigeria, exist to substantiate any claim. Safety standards exist for radiation from cell phone but these are not reassuring. This paper investigates any possible effect of GSM mobile phone radiation on human heart rate and then come out with conclusion based on experimental proof. Over one hundred human subjects were monitored by measuring their pulse rate under three exposure criteria. In one of the radiation tests, the phone used was put in vibration mode in order to determine subjects were not just responding to vibration. It was found out pulse rate do not change significantly when subjects were exposed to phone radiation. However, the percentage decrease recorded by people of age 40 years and above, even though barely above 1% makes it advisable that people of age 40 years and above should avoid keeping mobile phones close to the heart.

  19. Integrated monitoring and surveillance system demonstration project

    International Nuclear Information System (INIS)

    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

  20. Delta count-rate monitoring system

    International Nuclear Information System (INIS)

    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

    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)

    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 monitoring in a wide range of other applications such as: long sub sea flow lines; offshore riser systems; settlement in tank farms; facilities perimeter security. An important element of this system is a bespoke direct-bury optical sensor cable, designed to allow distributed strain measurement and hence enable monitoring of ground movement, whilst withstanding the rigors of the pipeline environment. The system can also be configured for detection of third-party interference and leaks with the majority of existing buried cables. In this paper, we outline the optical sensing methods employed in the system, and the results of the extensive field trials performed to fully evaluate and prove the system for use on long hydrocarbon transmission pipelines. Specifically, we will describe the detection of small gas releases, simulated ground movement and detection and recognition of a number of different types of third party interventions at the full 100 km target range. Finally, the tracking of a pig during pigging operations is demonstrated on a pilot installation. (author)

    This paper presents an innovative approach for a monitoring system, with applicability for water environments, based on a previous state of the art regarding both communication challenges in water and underwater monitoring but also the technologies which may be used in such surroundings. The system is based on an underwater sensors network which is connected to a cloud platform by means of a reconfigurable wireless transceiver. The sensor network integrates several low cost sensors that can measure different parameters such as water level, the water flow, temperature, pressure etc. The paper analyzes the measured parameters that will be transmitted through an operational communication node, which is able to ensure a reliable communication with timing and variation delay constraints. The cloud platform collects and stores the environmental data received from the targeted locations. Finally, the paper describes the platform interface available to end users, which will provide a real time visualization of the water environment events.

    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.

    International Nuclear Information System (INIS)

    This report describes a microcomputer-based monitoring and control system devised within, and used by, the Cryogenic Operations group at SLAC. Presently, a version of it is operating at the one meter liquid hydrogen bubble chamber augmenting the conventional pneumatic and human feedback system. Its use has greatly improved the controlled tolerances of temperature and pulse shape, and it has nearly eliminated the need for operating personnel to adjust the conventional pneumatic control system. The latter is most important since the rapid cycling machine can demand attentions beyond the operator's skill. Similar microcomputer systems are being prepared to monitor and control cryogenic devices situated in regions of radiation which preclude human entry and at diverse locations which defy the dexterity of the few operators assigned to maintain them. An IMSAI 8080 microcomputer is basic to the system. The key to the use of the IMSAI 8080 in this system was in the development of unique interface circuitry, and the report is mostly concerned with this

    International Nuclear Information System (INIS)

    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.

Stavroulakis (Ed.), Biological Effects of Electromagnetic Fields, Springer, 2003, pp. 545''578], which had shown a large decrease in the oviposition of the same insect caused by GSM radiation. Our present results suggest that the decrease in oviposition previously reported, is due to degeneration of large numbers of egg chambers after DNA fragmentation of their constituent cells, induced by both types of mobile telephony radiation. Induced cell death is recorded for the first time, in all types of cells constituting an egg chamber (follicle cells, nurse cells and the oocyte) and in all stages of the early and mid-oogenesis, from germarium to stage 10, during which programmed cell death does not physiologically occur. Germarium and stages 7''8 were found to be the most sensitive developmental stages also in response to electromagnetic stress induced by the GSM and DCS fields and, moreover, germarium was found to be even more sensitive than stages 7''8.

    2003-05-01

    Full Text Available Abstract Background The purpose was to investigate mobile phone interference with implantable deep brain stimulators by means of 10 different 900 Mega Hertz (MHz and 10 different 1800 MHz GSM (Global System for Mobile Communications mobile phones. Methods All tests were performed in vitro using a phantom especially developed for testing with deep brain stimulators. The phantom was filled with liquid phantom materials simulating brain and muscle tissue. All examinations were carried out inside an anechoic chamber on two implants of the same type of deep brain stimulator: ITREL-III from Medtronic Inc., USA. Results Despite a maximum transmitted peak power of mobile phones of 1 Watt (W at 1800 MHz and 2 W at 900 MHz respectively, no influence on the ITREL-III was found. Neither the shape of the pulse form changed nor did single pulses fail. Tests with increased transmitted power using CW signals and broadband dipoles have shown that inhibition of the ITREL-III occurs at frequency dependent power levels which are below the emissions of GSM mobile phones. The ITREL-III is essentially more sensitive at 1800 MHz than at 900 MHz. Particularly the frequency range around 1500 MHz shows a very low interference threshold. Conclusion These investigations do not indicate a direct risk for ITREL-III patients using the tested GSM phones. Based on the interference levels found with CW signals, which are below the mobile phone emissions, we recommend similar precautions as for patients with cardiac pacemakers: 1. The phone should be used at the ear at the opposite side of the implant and 2. The patient should avoid carrying the phone close to the implant.

    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 frequency of the TDC s pulse width modulated outputs is approximately 40 kHz. In this system, the technique is implemented by means of a monitoring circuit that includes a 20-MHz sampling circuit and a 24-bit accumulator with a gate time of 10 ms. The monitoring circuit measures the duty cycle of each of the 12 TDCs at a repetition rate of 28 Hz. The accumulator content is reset to all zeroes at the beginning of each measurement period and is then incremented or decremented based of the value of the state of the pulse width modulated signal. Positive or negative values in the accumulator correspond to duty cycles greater or less, respectively, than 50 percent.

    2011-01-01

    A system was designed to automate cryogenically cooled low-noise amplifier systems used in the NASA Deep Space Network. It automates the entire operation of the system including cool-down, warm-up, and performance monitoring. The system is based on a single-board computer with custom software and hardware to monitor and control the cryogenic operation of the system. The system provides local display and control, and can be operated remotely via a Web interface. The system controller is based on a commercial single-board computer with onboard data acquisition capability. The commercial hardware includes a microprocessor, an LCD (liquid crystal display), seven LED (light emitting diode) displays, a seven-key keypad, an Ethernet interface, 40 digital I/O (input/output) ports, 11 A/D (analog to digital) inputs, four D/A (digital to analog) outputs, and an external relay board to control the high-current devices. The temperature sensors used are commercial silicon diode devices that provide a non-linear voltage output proportional to temperature. The devices are excited with a 10-microamp bias current. The system is capable of monitoring and displaying three temperatures. The vacuum sensors are commercial thermistor devices. The output of the sensors is a non-linear voltage proportional to vacuum pressure in the 1-Torr to 1-millitorr range. Two sensors are used. One measures the vacuum pressure in the cryocooler and the other the pressure at the input to the vacuum pump. The helium pressure sensor is a commercial device that provides a linear voltage output from 1 to 5 volts, corresponding to a gas pressure from 0 to 3.5 MPa (approx. = 500 psig). Control of the vacuum process is accomplished with a commercial electrically operated solenoid valve. A commercial motor starter is used to control the input power of the compressor. The warm-up heaters are commercial power resistors sized to provide the appropriate power for the thermal mass of the particular system, and typically provide 50 watts of heat. There are four basic operating modes. "Cool " mode commands the system to cool to normal operating temperature. "Heat " mode is used to warm the device to a set temperature near room temperature. "Pump " mode is a maintenance function that allows the vacuum system to be operated alone to remove accumulated contaminants from the vacuum area. In "Off " mode, no power is applied to the system.

  5. Expert systems for protective monitoring of facilities

    International Nuclear Information System (INIS)

    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. The new FTU continuous monitoring system

    International Nuclear Information System (INIS)

    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

  7. Downhole Vibration Monitoring and Control System

    2007-09-30

    The objective of this program is to develop a system to both monitor the vibration of a bottomhole assembly, and to adjust the properties of an active damper in response to these measured vibrations. The key feature of this system is its use of a magnetorheological fluid (MRF) to allow the damping coefficient to be changed extensively, rapidly and reversibly without the use of mechanical valves, but only by the application of a current. Phase I of this program, which entailed modeling and design of the necessary subsystems and design, manufacture and test of a full laboratory prototype, was completed on May 31, 2004. Much of the effort was devoted to the design and testing of the MRF damper, itself. The principal objectives of Phase II were: more extensive laboratory testing, including the evaluation of different feedback algorithms for control of the damper; design and manufacture of a field prototype system; and, testing of the field prototype in a drilling laboratory. Phase II concluded on January 31, 2006, and a final report was issued. Work on Phase III of the project began during the first quarter, 2006, with the objectives of building precommercial prototypes, testing them in a drilling laboratory and the field; developing and implementing a commercialization plan. All of these have been accomplished. The Downhole Vibration Monitoring & Control System (DVMCS) prototypes have been successfully proven in testing at the TerraTek drilling facility and at the Rocky Mountain Oilfield Test Center (RMOTC.) Based on the results of these tests, we have signed a definitive development and distribution agreement with Smith, and commercial deployment is underway. This current version of the DVMCS monitors and controls axial vibrations. Due to time and budget constraints of this program, it was not possible to complete a system that would also deal with lateral and torsional (stick-slip) vibrations as originally planned; however, this effort is continuing without DOE funding.

    Full Text Available Location estimation using the Global System for Mobile Communication (GSM is an emerging application that infers the location of the mobile receiver from multiple signals measurements. The approach is based on the use of an inherent feature of the GSM cellular system and on the use of this information to estimate the phone’s location. Mobile positioning is the key aspect in providing the location based services. To offer reliable Location Based Services (LBS of 3G communication, accurate position estimate of Mobile Station (MS is essential. In the present technology, there is various position techniques are based on estimation of either time, angle and are economic. This work presents a new simple approach, to find MS position using Received Signal Strength (RSS measurements and is based on pdf of RSS probability method which in turns results with improved accuracy and reduction in minimum mean square error (MMSE. It turns out to be significantly beneficial, enhancing estimation accuracy and thereby enabling high-performance mobile positioning in a practical and cost effective manner. Experimental observed results are verified with Global Positioning System (GPS receiver measurements and found reasonably matching.

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

    International Nuclear Information System (INIS)

    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 ?T 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

    2013-01-01

    Full Text Available Ship-To-Ship (STS crude oil transfer at sea is an operation where crude oil is transferred between seagoing ships moored alongside each other. Due to the complex sea conditions and the poorer lightering facilities compared with the port operations, the risk of the operations is higher. Even though the frequency of incidents involving lager oil tankers has been reduced during recent decades, the consequences of such incidents can be very serious. In order to enhance regulation of STS operation and reduce risk of oil spill accidents, the study examined the existing regulation system and proposed an enhanced intelligent regulation system supported by modern Internet of Things technology. The framework of the intelligent regulation system was described in detail which included several intelligent monitoring means and a decision support system based on risk assessment.

  13. Development of the real time monitor system

    International Nuclear Information System (INIS)

    Large-scale simulation technique is studied at the Center for Promotion of Computational Science and Engineering (CCSE) for the computational science research in nuclear fields. Visualization and animation processing technique are studied and developed for efficient understanding of simulation results. The real time monitor system, in which on-going simulation results are transferred from a supercomputer or workstation to a graphic workstation and are visualized and recorded, is described in this report. This system is composed of the graphic workstation and the video equipment connected to the network. The control shell programs are the job-execution shell for simulations on supercomputers, the file-transfer shell for output files for visualization, and the shell for starting visualization tools. Special image processing technique and hardware are not necessary in this system and the standard visualization tool AVS and the UNIX commands are used, so that this system can be implemented and applied in various computer environments.

    2011-03-01

    In the present double-blind, randomized, sham-controlled cross-over study, possible effects of electromagnetic fields emitted by Global System for Mobile Communications (GSM) 900 and Wideband Code-Division Multiple Access (WCDMA)/Universal Mobile Telecommunications System (UMTS) cell-phones on the macrostructure of sleep were investigated in a laboratory environment. An adaptation night, which served as screening night for sleep disorders and as an adjustment night to the laboratory environment, was followed by 9 study nights (separated by a 2-week interval) in which subjects were exposed to three exposure conditions (sham, GSM 900 and WCDMA/UMTS). The sample comprised 30 healthy male subjects within the age range 18-30 years (mean ± standard deviation: 25.3 ± 2.6 years). A cell-phone usage at maximum radio frequency (RF) output power was simulated and the transmitted power was adjusted in order to approach, but not to exceed, the specific absorption rate (SAR) limits of the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines for general public exposure (SAR(10g) = 2.0 W kg(-1)). In this study, possible effects of long-term (8 h) continuous RF exposure on the central nervous system were analysed during sleep, because sleep is a state in which many confounding intrinsic and extrinsic factors (e.g. motivation, personality, attitude) are eliminated or controlled. Thirteen of 177 variables characterizing the initiation and maintenance of sleep in the GSM 900 and three in the WCDMA exposure condition differed from the sham condition. The few significant results are not indicative of a negative impact on sleep architecture. From the present results there is no evidence for a sleep-disturbing effect of GSM 900 and WCDMA exposure.

  15. Environmental radiation monitoring system in nuclear medical facilities

    International Nuclear Information System (INIS)

    The radiation monitoring systems in nuclear medical facilities are explained. Liquid effluent monitors and dust-gas monitors are described. The monitoring of liquid effluent can be done by measuring beta-ray or gamma-ray of samples. The gamma-ray is continuously measured with NaI(Tl) scintillation counters. The detection efficiency is larger than that of beta-ray counters. The sensitivity coefficients and maximum detection sensitivity of both types for various nuclides are shown in tables. The beta-ray is measured with plastic scintillation counters which are used for monitoring the nuclides with no gamma-ray. The dust monitors used in medical facilities are usually continuously feeding filter paper dust monitors and movable type fixed filter paper dust monitors. The continuously feeding filter paper dust monitors collect radioactive dust on moving filter papers, and the beta-ray from the dust is measured with end-window G-M counters. The movable type monitors can be moved to the position where the monitoring should be done. Two types of gas monitors are used for monitoring radioactive gas. The ionization chamber type monitors are used for tritium, and the plastic scintillation type monitors are used for other gas. Other equipments for the monitoring are area monitors, hand-foot-cloth monitors and floor monitors. (Kato, T.)

    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...

    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.

  20. HTS subsystem formed by 12-pole filter for GSM1800 mobile communication

    International Nuclear Information System (INIS)

    High temperature superconductor (HTS) microwave filter was designed for Global System for Mobile Communication (GSM)1800 system. The center frequency and the transmission fractional bandwidth of the 12-pole micro-strip line filter were designed as 1750 MHz and 4.3% respectively. The filter was fabricated on 30 mmx19 mmx0.5 mm LaAlO3 wafer that was double side coated with YBCO thin films. At the temperature of 70 K, the filter has the insertion loss less than 0.48 dB, and the out-band rejection higher than 65 dB. Assembled with a low noise amplifier, the 12-pole filter formed the receive front of GSM1800 base station. The HTS receive front was tested by Datang's lab and showed the good performance. The gain of the receive front is 22.5 dB and the noise figure of the receive front is less than 0.6 dB

    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.

  2. Fence line noble gas monitoring system

    International Nuclear Information System (INIS)

    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)

    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?

  8. Intelligent data monitoring for advanced control systems

    International Nuclear Information System (INIS)

    Data monitoring is a key issue for the development of efficient, reliable control systems in the process industries as in the nuclear power plants. Conventional analog systems are being replaced by a new generation of process control systems that provide higher level concepts allowing intelligent filtering and diagnosis systems. Advanced knowledge-based technologies have already been introduced in industrial production systems. However these approaches have several drawbacks: the integration within such systems of knowledge-based components implies that these latter offer facilities for representing the process dynamics, i.e. facilities for programming temporal knowledge and reasoning, the control system itself must be able to exploit these temporal data and reasoning schema with satisfaction of the real-time constraints. One main problem is thus to deal with this permanently evolving image of the plant, by selecting at the earliest possible moment, relevant information that will become evidences for the diagnosis process, and deleting as soon as possible useless data. An approach to this problem based on an intelligent forgetting algorithm that limits the amount of data stored for the temporal reasoning and allows a distributed follow-up of critical information is proposed. Knowledge about possible critical event sequences is dispatched onto specific modules that can be located as close as possible to the data sources. A representation system for temporal knowledge and an actor based programming is also presented. (11 refs.)

  10. Monitored Retrievable Storage System Requirements Document

    International Nuclear Information System (INIS)

    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

  1. Automatic monitoring system on LLW transportation

    International Nuclear Information System (INIS)

    Low level radioactive wastes (LLW) generated from Japanese nuclear power plants are mostly stuffed in steel drums and packed in containers, eight in each. Some 400 of such containers are transported by a specially built ship, the 'Seiei Maru' to the Mutu-Ogawara Port in Rokkasho-mura, Aomori Prefecture and transported overland by specially designed vehicles to the nearby LLW Disposal Center. Before leaving nuclear power plants all LLW packages are inspected for radiation dose rate to confirm that they satisfy the applicable regulations. Although the radiation level around the packages are not thought to increase during the voyage, it was decided to carry out the same measurement again at the port of arrival to demonstrate to the local public that the transport is not a matter concern. Prior to system development, number and position of optimal measurement points around the vehicle, and also possible measurement method were examined. This was realized by means of geometrical modeling of the containers and vehicle and then evaluating the dose rates at the reference points. Taking into account of the results, we have developed the automatic radiation monitoring system (Gate Monitor) for measurement of LLW containers which are loaded on a vehicle. The purpose is as follows: (1) Reduction of personnel radiation exposure. Approximately 60 turn-arounds of vehicles are daily required to transfer the LLW packages from the port to the LLW Disposal Center and the reduction of inspectors radiation exposure is strongly requested. (2) Reduction of personnel for radiation measurement. The period of time allowed for radiation measurement is about 4 minutes per truck and 5 to 6 persons will have to be engaged in such operation. Therefore reduction of personnel for radiation measurement is requested. (3) Enhancement of safety and workability. Radiation measurement is carried out at the quay, outdoor, cold and snowy in winter season. Therefore remote and automatic operation is requested for personnel safety and workability. (4) Reliability of measurement. For the sake of quality assurance in transport operations the results of the measurement should be maintained in the same level of accuracy and mechanical and automatic system is most suited for such purpose. (5) Ease of recording and management of data. A system of radiation survey meters and data processor is requested to record and process a large amount of data. A specific measuring system is requested for the ease of recording and management of data. Since December 1992 this Gate Monitor has been in use and 7,921 vehicles have been measured as of August 1999. The Gate Monitor has been operated all year around, even under winter snow storms and we have not experienced any breakdowns, although there have been some cases of dead batteries and incorrect alignment of the vehicle in the Gate Monitor.

  2. Exposure to low level GSM 935 MHz radiofrequency fields does not induce apoptosis in proliferating or differentiated murine neuroblastoma cells

    International Nuclear Information System (INIS)

    The aim of this study was to investigate whether radiofrequency (RF) fields characteristic of mobile phones at non-thermal levels can induce apoptosis in murine neuroblastoma (N2a) cells in both proliferating and differentiated states. Cells were exposed continuously for 24 h to one of the three 935-MHz RF signals: global system for mobile communication (GSM) basic, GSM talk and a continuous wave, unmodulated signal; all at a specific energy absorption rate of 2 W kg-1. The measured increase in temperature of the cells due to the RF fields was around 0.06 deg. C. At a number of time points between 0 and 48 h post-exposure, the cells were assessed for apoptosis under a fluorescence microscope using three independent assays: Annexin V, caspase activation and in situ end-labelling. No statistically significant differences in apoptosis levels were observed between the exposed and sham-exposed cells using the three assays at any time point post-exposure. These data suggest that RF exposures, characteristic of GSM mobile phones, do not significantly affect the apoptosis levels in proliferating and differentiated murine neuroblastoma cell line N2a.

  3. An imaging contamination monitoring system for surfaces

    International Nuclear Information System (INIS)

    A novel system for monitoring surfaces for radioactive contamination has been developed. The system uses audible and visual identification methods to provide natural coactivation clues to an operator, resulting in enhanced sensitivity to areas of surface contamination. The system utilizes position-sensing proportional counter detectors, and includes a head-mounted display that provides the user with a real-time, three-dimensional image to allow for instant recognition of surface contamination. This visual information is augmented with audio input in the form of background-subtracted stereo clicks. Time-stamped survey data is stored for later retrieval, providing for additional analysis using a digital imaging workstation. The system is motorized to provide constant speed during surveys, and surveys are recorded with a video camera to allow identification of locations of contamination using the time index from the stored data. The system has been used to conduct surveys at several facilities throughout the southeast, including the Y-12 and K-25 sites in Oak Ridge, Tennessee, and EPA facilities in Montgomery, Alabama. It was demonstrated that the system could perform surveys at much greater rates than with conventional methods, with equal or better detection performance and with documentation so complete that an entire survey could be reexamined at a later date with the reviewer able to see what the original surveyor saw, including display indications and the surface thing display indications and the surface that was monitoredA novel system for monitoring surfaces for radioactive contamination has been developed.

  6. The Automator: Intelligent Control System Monitoring

    International Nuclear Information System (INIS)

    A large-scale control system may contain several hundred thousand control points which must be monitored to ensure smooth operation. Knowledge of the current state of such a system is often implicit in the values of these points and operators must be cognizant of the state while making decisions. Repetitive operators requiring human intervention lead to fatigue, which can in turn lead to mistakes. The authors propose a tool called the Automator based on a middleware software server. This tool would provide a user-configurable engine for monitoring control points. Based on the status of these control points, a specified action could be taken. The action could range from setting another control point, to triggering an alarm, to running an executable. Often the data presented by a system is meaningless without context information from other channels. Such a tool could be configured to present interpreted information based on values of other channels. Additionally, this tool could translate numerous values in a non-friendly form (such as numbers, bits, or return codes) into meaningful strings of information. Multiple instances of this server could be run, allowing individuals or groups to configure their own Automators. The configuration of the tool will be file-based. In the future, these files could be generated by graphical design tools, allowing for rapid development of new configurations. In addition, the server will be able to explicitly maintain information about the state of the control system. This state information can be used in decision-making processes and shared with other applications. A conceptual framework and software design for the tool are presented

  12. The compact surveillance and monitoring system 'COSMOS'

    International Nuclear Information System (INIS)

    The Japan Atomic Energy Research Institute (JAERI) has developed a surveillance video camera device named 'COSMOS' (Compact Surveillance and Monitoring System) for the replacement of the Twin Minolta Film Camera system that have been used by the International Atomic Energy Agency (IAEA). Since the Minolta Company was reported to cease the production of the relevant camera, the JAERI started the development under the Japanese Support Programme for the Agency Safeguards (JASPAS). A COSMOS system consists of two units; one is a main unit and the other is a set-up/review unit. The main unit consists of three parts, i.e., four modules, a main frame and a tamper-indicating housing. The four modules are a small CCD camera module with an auto-iris lens and an 8 mm VTR module that is specifically designed for COSMOS, a video frame memory module, a system control module, and DC or AC power supply module. The most important target in the COSMOS design is to achieve a long period operation with low power consumption, which enables the system operate for three months with one battery, and produce 30,000 shots with 5 minutes time interval. The IAEA carried out its reliability tests and field tests and completed with successful results, with which the IAEA approved the COSMOS as an authorized equipment for IAEA inspection use. This report describes the function and operation of the COSMOS, which are particularly needed at the stage of its installation. (author)

  13. Atmospheric radioactivity monitoring system for the CTBT

    International Nuclear Information System (INIS)

    The Comprehensive Test Ban Treaty (CTBT), which was signed in September, 1996, bans the testing of nuclear weapons in any environment. It is now in a preparatory phase, which will lead to the development of an international verification regime to ensure that the Treaty is not violated. A key component of this regime will be an International Monitoring System (IMS) to monitor global environments, consisting of four components: 1)a network of 50 seismic stations to detect underground explosions, supplemented by an additional network of 120 national seismic facilities. 2)network of 11 hydro-acoustic stations to detect underwater explosions. 3) a network of 80 radionuclide stations to detect atmospheric explosions and vented radionuclides from underground or underwater explosions. 4) a network of 60 infra-sound stations to detect atmospheric explosions. The radionuclide monitoring network will be capable of detecting very low levels of atmospheric fission products. Also, it will provide a means of discriminating between radionuclides originating from a nuclear explosion and those from other sources, such as normal or accidental emissions from a nuclear power station or a reprocessing plant and discharges from a medical isotope production facility. This network is, in fact, the only component of the IMS which will be able to confirm that an explosion is nuclear. Data from each of the stations in the four IMS networks will be transmitted to an International Data Centre (IDC) currently being established in Vienna, where processing and analysis will take place. The IDC will characterise any event detected and merge information gathered by the four technologies when appropriate. A prototype centre in Washington, USA has been gathering radionuclide data for 2 years from approximately 20 national stations, including several in Australia, and this experience has been invaluable in the current development program for the IMS network

  18. Seals monitoring systems using wireless communications

    International Nuclear Information System (INIS)

    Document available in extended abstract form only. Wireless monitoring based on electromagnetic waves is a promising application for deep geological nuclear waste repositories. It should allow data transmission without installing wires across the various seals (disposal cell plugs, gallery plugs, shaft plugs). Developments of the wireless system (e.g. transmitter and receiver) are in progress in order to fit the repository requirements. A common research program has been elaborated by RWMC and Andra. The present work aims at developing the wireless monitoring technology to intermediate level waste (ILW) disposal facilities concept. In this concept, ILW packages will be emplaced in disposal cells with concrete liner. After the operational phase, the cells will be backfilled with sealing material. In practice, this work demonstrates the feasibility of adapting and optimizing the wireless transmission system for specific repository cases. After preliminary transmission studies, it was decided to make a representative test in situ of a wireless transmission through the clay from a sealed side to an accessible side of the repository. In order to reduce the attenuation of magnetic flux caused by steel components between the transmitter and the receiver, the receiving antenna is installed in a dedicated borehole (drilled from the accessible side). Two types of reception antennas have been designed. According to its coil orientation, type A antenna measures the electromagnetic wave perpendicular to the borehole axis. On the other hand, type B antenna with a coil set in-line with the tubular casing, measures the electromagnetic wave parallel to the borehole axis. The outside cylinder (pressure tight case) is made of PVC considering the attenuation of electromagnetic flux. According to the direction of electromagnetic flux and position of the boreholes in the final repository design, type A or type B will be chosen. For the 'representative' test, a borehole, TSF1002 has been drilled in the first experimental gallery of Andra's underground laboratory. On the 'sealed' side, e.g. TSF1001 (400 mm of diameter), a battery-powered monitoring system has been installed. This autonomous system includes three pressure sensors and a temperature probe. As shown in figure 2, wireless transmission and measurements have been perfectly working since the installation. This transmission is designed to last more than ten years. In figure 2, blue and brown lines show the pressure variation in the TSF1001 boreholes, between -4 and -7 m, where 3 meters of bentonite are hydrated periodically. Since September 2011, water has been added in this borehole, in order to increase the bentonite pressure (cf. PRT measurements on the time chart). The green clear curve, related to the pore water pressure, indicates that the bentonite is not totally hydrated. When the saturation mechanism will begin, the pore water pressure will increase. Transmission numerical analyses Numerical analyses were carried out by using software for three-dimensional electromagnetic field analyses called JMAG. In order to analyze the electromagnetic phenomena which occurred in the drifts and boreholes, precise modeling of electromagnetic field and variety of materials which will affect the electromagnetic flux is inevitable. On this case, JMAG has an advantage of high capacity of analysis and efficiency of modeling. Figure 3 shows the magnetic density of all direction. A robust and efficient system was deployed for underground seal monitoring. The results of simulations of these wireless transmission match with the measured values. There is a case that the received voltage is higher than the theoretical value because the magnetic flux is amplified by the steel pipes. (authors)

  19. Standard-D hydrogen monitoring system, system design description

    International Nuclear Information System (INIS)

    During most of the year, it is assumed that the vapor space in the 177 radioactive waste tanks on the Hanford Project site contain a uniform mixture of gases. Several of these waste tanks (currently twenty-five, 6 Double Shell Tanks and 19 Single Shell Tanks) were identified as having the potential for the buildup of gasses to a flammable level. An active ventilation system in the Double Shell Tanks and a passive ventilation system in the Single Shell Tanks provides a method of expelling gasses from the tanks. A gas release from a tank causes a temporary rise in the tank pressure, and a potential for increased concentration of hydrogen gas in the vapor space. The gas is released via the ventilation systems until a uniform gas mixture in the vapor space is once again achieved. The Standard Hydrogen Monitoring System (SHMS) is designed to monitor and quantify the percent hydrogen concentration during these potential gas releases. This document describes the design of the Standard-D Hydrogen Monitoring System, (SHMS-D) and its components as it differs from the original SHMS

  20. INFN-CNAF Monitor and Control System

    International Nuclear Information System (INIS)

    CNAF is the national center of National Institute of Nuclear Physics (INFN) for R and D in the field of Information Technologies applied to High Energy Physics (HEP) experiments. It is involved in the management and development of the most important information and data handling services in behalf of the INFN. In 2005, the Italian Tier-1 for Large Hadron Collider (LHC) experiments has been inaugurated at INFN-CNAF. Due to the huge complexity of Tier-1 center, the use of control systems is fundamental for management and operation of the center. At INFN-CNAF, several solutions have been adopted, from commercial to open source products up to entirely home-made systems. Adopted open source solutions have been strongly adapted to specific needs; a wide set of customized sensors has been developed for various divisions like Network, Storage, Farming, Grid operation and National Services. Finally, a dashboard has been developed, to which described control systems send critical alarms (sent via sms to an operator as well). The dashboard can be exploited to get an historical view of the Tier-1 and national services' state and to allow a quick web control. In this article, the whole system, adopted customizations in monitoring and control as well as their integrations with the dashboard will be described.
