CERN GSM monitoring system  

CERN Document Server

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...

GSM BASED IRRIGATION CONTROL AND MONITORING SYSTEM  

Directory of Open Access Journals (Sweden)

Full Text Available Irrigated agriculture is one of the primary water consumers in most parts of the world. With developments in technology, efforts are being channeled into automation of irrigation systems to facilitate remote control of the irrigation system and optimize crop production and cost effectiveness. This paper describes an on-going work on GSM based irrigation monitoring and control systems. The objective of the work is to provide an approach that helps farmers to easily access, manage and regulate their irrigation systems for the water needs of crops using SMS technology for data transportation. A prototype irrigation controller system, which is a closed-loop digital control system, was implemented to continuously monitor the soil moisture level, control parameters, irrigation scheduling plan, and output of the pumping system to manage and control of the irrigation systems.The controller system comprises processor module, GSM module, soil sensing system, pump switching system, regulated power supply system, and intrusion detection system. To validate the performance and functionality of the controller system, field experiments were conducted. Test results show that the SMS could provide a simpleand easy means for users to directly access and manage their irrigation systems. Tests on different cellular networks revealed an average response time of 16 seconds from the time of SMS request to the controller system to read data or activate the irrigation system through data processing and submission to user. The GSM based irrigation system may offer users the flexibility to regulate and control the operations of their irrigation systems with little intervention to reduce runoff from over watering for improvement in crop yield.

Industrial Pollution Monitoring System Using Labview And Gsm  

Directory of Open Access Journals (Sweden)

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.

Directory of Open Access Journals (Sweden)

Full Text Available Nontechnical losses (NTL during transmission of electrical energy are a main problem in developing countries. It is so complicated for the utility companies to detect and fight the people responsible for the theft. Electricity theft forms a main chunk of non technical losses (NTL. These losses affect the quality of supply, increase load on the generating station, and affect tariff forced on actual consumers. This paper shows some common methods used by consumers for electricity theft and also proposes an architectural distribution system for theft detection using GSM based smart energy meter. The Inspiration of this work is to detect illegal consumers, preserve and successfully utilize energy. As well as smart meters are proposed to provide automatic readings/data of dissimilar parameters related to instantaneous power consumption via GSM. It will reduce the laborious task and financial expenditure by adopting the automatic meter reading instead of the manual meter reading process and bill data entry process.

Solar powered environmental radiation monitor with GSM based data communication  

International Nuclear Information System (INIS)

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

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)

A Secure Parking Reservation System Using GSM Technology  

Directory of Open Access Journals (Sweden)

Full Text Available In this paper, a secure parking reservation system using Global System for Mobile communications (GSM technology has been performed. It helps the drivers from facing the problem that always occurs at the car park, such as time being wasted in searching for the available parking spaces and keep on circling the parking area until they found an empty parking spot. This problem usually occurs in urban areas, where number of vehicles are higher as compared to the availability of parking spaces. In this proposed system there are two modules have been developed such as parking lot monitoring and security reservation modules. For the parking lot monitoring module, the layout animation is used to display the parking lot status. In security reservation module, the users need to send SMS to reserve the parking lot and use the password provided to enter and exit the parking lot. Our main contribution is the system has more security than other previous research with the used of password to enter and exit.

RFID, GPS & GSM Based Vehicle Tracing & Employee Security System  

Directory of Open Access Journals (Sweden)

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.

Fake BTS Attacks of GSM System on Software Radio Platform  

Directory of Open Access Journals (Sweden)

Full Text Available The 2G GSM communication system only provides one-way authentication mechanism which just authenticate the identities of mobile users. As we know, this is not resistant to fake BTS attack. But for the huge cost for building a fake BTS before, this kind of attack were not really implemented before. This paper presents an implement of fake BTS based on software radio technologies. Furthermore, this paper discusses two types of fake BTS attacks on our software radio platform. The first attack is IMSI/IMEI catch attack, which can get the mobile phone’s IMSI and IMEI. With this information, attacker can got the track of the man with this phone. The second attack is selective jamming attack. After get the IMSI and IMEI of the mobile phone, the attackers can decide whether the mobile phone is blocked or not. We will analyze the GSM protocol which is relevant to the interception system and later present the performance of such a system by real tests and demonstrate its feasibility.

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

Science.gov (United States)

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

Intelligent GSM Cell Coverage Analysis System Based on GIS  

Directory of Open Access Journals (Sweden)

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.

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/

Medical reliable network using concatenated channel codes through GSM network.  

Science.gov (United States)

Although the 4(th) generation (4G) of global mobile communication network, i.e. Long Term Evolution (LTE) coexisting with the 3(rd) generation (3G) has successfully started; the 2(nd) generation (2G), i.e. Global System for Mobile communication (GSM) still playing an important role in many developing countries. Without any other reliable network infrastructure, GSM can be applied for tele-monitoring applications, where high mobility and low cost are necessary. A core objective of this paper is to introduce the design of a more reliable and dependable Medical Network Channel Code system (MNCC) through GSM Network. MNCC design based on simple concatenated channel code, which is cascade of an inner code (GSM) and an extra outer code (Convolution Code) in order to protect medical data more robust against channel errors than other data using the existing GSM network. In this paper, the MNCC system will provide Bit Error Rate (BER) equivalent to the BER for medical tele monitoring of physiological signals, which is 10(-5) or less [1]. The performance of the MNCC has been proven and investigated using computer simulations under different channels condition such as, Additive White Gaussian Noise (AWGN), Rayleigh noise and burst noise. Generally the MNCC system has been providing better performance as compared to GSM. PMID:24110797

Development of a Secured Security System for an Automobile using GSM Technology and Electronic Circuit  

Directory of Open Access Journals (Sweden)

Full Text Available This paper focuses on the design and development of a security system for an automobile using GSM technology and electronic circuit which is being used to prevent or control the theft of a vehicle. The case of car hijacking has become so rampant that it has become a threat to the world leaders. Some of them cannot drive their expensive cars without escort plus the sounding of siren to scare the evil perpetrators. The necessity of car security cannot be overemphasized by car owners due to high cost of purchasing car nowadays. Car security system using GSM and Electronic circuit had been designed, which can operate in two ways: receiving signal / command from the car owner through the mobile phone or by taken decision by itself using electronic circuit. The signal received through the mobile phone that serves as input to the circuit and immediately sends signal through transistor TR1 and TR2 to the 555 timer IC1 to other transistors in the circuit and output of one transistor serves as input signal to another. The output signal from the PIC 16F84A or CD 4017 demobilized the central lock system and brain box of the car. The demobilized central lock system and brain box can be reset by calling or sending another signal through the mobile phone to reset the brain box.

Dosimetric assessment of an exposure system for simulating GSM and WCDMA mobile phone usage.  

Science.gov (United States)

An exposure system for investigation of volunteers during simulated GSM and WCDMA mobile phone usage has been designed. The apparatus consists of a dual band antenna with enhanced carrying properties that enables exposure for at least 8 h a day. For GSM a 900 MHz pulse modulated carrier was used. The QPSK modulated WCDMA signal at 1966 MHz comprises a power control scheme, which was designed for investigations of biological effects. The dosimetry of the exposure system by measurements and calculations is described in detail within this paper. It is shown that the SAR distribution of the antenna shows similar characteristics to mobile phones with an integrated antenna. The 10 g averaged localized SAR, normalized to an antenna input power of 1 W and measured in the flat phantom area of the SAM phantom, amounts to 7.82 mW/g (900 MHz) and 10.98 mW/g (1966 MHz). The simulated SAR(10 g) in the Visible Human head model agrees with measured values to within 20%. A variation of the antenna rotation angle results in an SAR(10 g) change below 17%. The increase of the antenna distance by 2 mm with respect to the human head leads to an SAR(10 g) change of 9%. PMID:16557502

SECURE VOICE COMMUNICATION USING LOW BIT RATE SYSTEM FOR GSM USERS  

Directory of Open Access Journals (Sweden)

Full Text Available The ever popular world of wireless mobile communication is taking wide strides and is becoming to a greater extent more technologically advanced as compared to its predecessors. Mobile communications such as GSM (Global System for Mobile Communication is already widespread and supports a large number of subscribers all around the global. The voice traffic is on an increase over the already existing system thereby demanding bulk resources, increasing the overall cost and putting a limit to its use in the long run. The security of the voice traffic is also an issue of concern to avoid intrusion by nscrupulous elements over the mobile communication network. A bankable solution for this is to reduce the overall bit rate of the system while still maintaining toll-quality speech and providing security to the speech signal before its transmission over the network. The advantages benefited are efficient use of available bandwidth, robustness to errors, secure communication, and reliability and flexibility of the system.

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.

Multi-Functional Monitoring System  

Directory of Open Access Journals (Sweden)

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.

Remote Arrhythmia Monitoring System Developed  

Science.gov (United States)

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.

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

International Nuclear Information System (INIS)

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

This paper presents a new distribution transformer monitoring system (DTMS), called Wimo, which utilizes the existing communication network, has low investment and operation costs and is easy to install and use. The system is able to provide the following benefits for utilities: warnings and alarms in real time, measured and registered data of loadings, reactive power, earth current and power quality at the transformer substation, and more reliable and effective maintenance. Also, transformer capacity can be utilized more effectively and the control of power quality can be improved. The field tests of the first two installations in Finland have been promising and the system is shown to be compatible with the commercial GSM networks and with the information systems used in power networks.

FPGA based Remote Monitoring System for Food Preservation  

Directory of Open Access Journals (Sweden)

Full Text Available Food security is the assured access to adequate food that is nutritious, of good quality, safe and meets cultural needs. In food production industries, performing visits for 24 hours evaluation is a difficult and time consuming process. In order to improve monitoring level for food industries, an intelligent system has been designed. Eight analog parameters Temperature, PH, humidity, water activity, redox potential, pressure, concentration and CO2 are monitored. The data acquisition is done through eight analog potentiometers and the parameters are monitored using FPGA. The developed system has been tested with RTD temperature sensors and information is transmitted through wireless communication to user mobile at remote place if any failures occur in the system. Thus for good food quality, FPGA and GSM based remote monitoring is performed to improve the status of production. The work represents the idea of real time monitoring and control of multi sensors food security application. The system is low cost, flexible, fast and reconfigurable.

AUTOMATED EB BILLING SYSTEM USING GSM AND AD-HOC WIRELESS ROUTING  

Directory of Open Access Journals (Sweden)

Full Text Available With the passage of time, technology has merged itself with the daily life of humans. We have seen so much progress in the field of science and technology but we are not able to make full use of it. One such area for improvement is the Electricity board billing system. Our existing electricity board billing system in India is obsolete and time consuming. We are proposing a system through which electricity billing becomes fully automated and communication is made possiblevia wireless networks. The existing manual system in India has major drawbacks. This system is prone to errors and can also be easily manipulated. The prevailing manual system also requires lot of human workforce. The major disadvantage in this system is that the meter cannot be accessed by the meter reader if the customer is not present at home. In our system the central EB office has immediate access to all consumer homes in a locality with the help of an RF system. The EB meter present in each house is connected by wireless network with the EB office which periodically gets updates from the meter. The EB office using a backend database calculates the amount to be paid according to the number of units consumed and sends it back to the meter for display and also to the user’s mobile phone. The advantages of the proposed system make the existing system incompetent. It ispossible to connect to remote areas even when there is a power failure as it employs wireless technology. The new system is user friendly, easy to access and far more efficient than the existing system.

Can LTE become an alternative to GSM-R?  

DEFF Research Database (Denmark)

GSM-R is the first widely adopted international mobile communication network for railways. It is a part of the European Rail Traffic Management System (ERTMS), which substitutes legacy national railway signaling technologies. GSM-R is designed to provide two fundamental services: transmission of the European Train Control System (ETCS) messages and voice communication for railways. ETCS system offers safe and reliable in-cab signaling and train supervision, which reduces the risk of train driver error and increases the track occupancy. Thus, GSM-R, as a basis for ETCS, contributes to the safety and the performance of railways [1].

Design of a GPS/GSM based tracker for the location of stolen items and kidnapped or missing persons in Nigeria  

Directory of Open Access Journals (Sweden)

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.

Two-way energy data communication with GSM; Toveis med GSM  

Energy Technology Data Exchange (ETDEWEB)

Enermet AS, Ericsson and Wireless Maingate have developed a new solution for two-way communication for remote reading of electricity meters via the GSM mobile telephone network. The collection of measurements by telephone is not a new concept, but the new method cuts the investment costs to less than one third and the operation costs to less than one fourth of the older method. There are two versions of the new method. One version uses traditional GSM data traffic combined with communication over the low-voltage network by means of LON-Works. Data are collected via the power grid in a low-voltage circuit containing for instance twenty houses each having its own meter and then periodically communicated to a central computer over the GSM system. The other version, which is the cheaper one, involves direct communication with each company or household. This method uses the GSM/SMS (Short Message Service) technique and is most appropriate for communication with one customer at a time. Using this new system, a utility may read off all its customers on for instance December 31 and send out the invoices to all of them the following week. The customer may use the GSM/SMS transmitter/receiver to communicate with his own house or cottage and connect or disconnect apparatuses and check various status indicators.

Simplified Monitoring System  

CERN Multimedia

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

Remote monitoring system enhancements  

International Nuclear Information System (INIS)

The Illinois Department of Nuclear Safety or IDNS is responsible for protecting the public from the hazards of radiation and radioactive materials. IDNS was created in 1980 following the accident at the Three Mile Island nuclear power plant in Pennsylvania. One part of the Department's responsibility is to recommend protective actions to the Governor in case of an accident at any of Illinois' 13 commercial nuclear power reactors. To handle that responsibility, IDNS has developed the most extensive remote reactor monitoring system in the nation. This state-of-the-art monitoring system has several components including: a computer linked data system so that IDNS can monitor important safety systems at the reactors; an in-stack monitor which analyzes gaseous emissions from each reactor, and a network of gamma radiation monitors which are located approximately 2 miles from each reactor and which are placed so that they encircle the plant. This paper focuses on the Department's plans for using photovoltaic power for the gamma radiation monitors which encircle the power plants. It describes the monitors and the importance of reliability of their power source; plans for testing photovoltaic power for these monitors; and progress to date on this project

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.

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

Directory of Open Access Journals (Sweden)

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.

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

Copilot: Monitoring Embedded Systems  

Science.gov (United States)

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.

VME system monitor board  

Energy Technology Data Exchange (ETDEWEB)

Much of the machinery throughout the APS will be controlled by VME based computers. In order to increase the reliability of the system, it is necessary to be able to monitor the status of each VME crate. In order to do this, a VME System Monitor was created. In addition to being able to monitor and report the status (watchdog timer, temperature, CPU (Motorola MVME 167) state (status, run, fail), and the power supply), it includes provisions to remotely reset the CPU and VME crate, digital I/O, and parts of the transition module (serial port and ethernet connector) so that the Motorla MVME 712 is not needed. The standard VME interface was modified on the System Monitor so that in conjunction with the Motorola MVME 167 a message based VXI interrupt handler could is implemented. The System Monitor is a single VME card (6U). It utilizes both the front panel and the P2 connector for I/O. The front panel contains a temperature monitor, watchdog status LED, 4 general status LEDs, input for a TTL interrupt, 8 binary inputs (24 volt, 5 volt, and dry contact sense), 4 binary outputs (dry contact, TTL, and 100 mA), serial port (electrical RS-232 or fiber optic), ethernet transceiver (10 BASE-FO or AUI), and a status link to neighbor crates. The P2 connector is used to provide the serial port and ethernet to the processor. In order to abort and read the status of the CPU, a jumper cable must be connected between the CPU and the System Monitor.

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

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)

Science.gov (United States)

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

Securing Speech in GSM Networks using DES with Random Permutation and Inversion Algorithm  

Directory of Open Access Journals (Sweden)

Full Text Available Global System for Mobile Communications (GSM is one of the most commonly used cellular technologies in the world. One of the objectives in mobile communication systems is the security of the exchanged data. GSM employs many cryptographic algorithms for security like A5/1, A5/2 and A5/3. Even so, these algorithms do not provide sufficient level of security for protecting the confidentiality of GSM. Therefore, it is desirable to increase security by additional encryption methods. This paper presents a voice encryption method called: “DES with Random permutation and Inversion”, based on current voice channel, which overcomes data channel's insufficiencies and solves the problem of penetrating the RPE-LTP vocoder by the encrypted voice. The proposed method fulfils an end-to-end secured communication in the GSM; insure a good compatibility to all GSM networks, and easy implementation without any modification in these systems.

Operating Objects Using RF Transmitters and Receivers through Mobile Phones via GSM after Authenticating Users with Fingerprint Analysis  

Directory of Open Access Journals (Sweden)

Full Text Available The paper aims to provide a system for monitoring and managing objects using Radio Frequency (RF transmitters and receivers, operating the objects using Global System for Mobile Communications (GSM via mobile phones, and authenticated access by fingerprinting analysis. An object represents an electronic device that can be programmed. This system is based on RF transmitters and receivers that are tagged to the electronic objects to be operated and have the capability of transmitting signals. A transmitter transmits the signal containing the object Identifier (ID and the system receiver detects this transmitted ID, and stores its corresponding information in the database which is created specifically for information maintenance of the tagged objects. Mobile phones are used to operate the tagged object by sending a message to the Subscriber Identity Module (SIM connected to a GSM modem. Once the system receives the fingerprint verification data and the operation code of the electronic tagged object via GSM modem, it fetches the relevant information from the database and encapsulates this information into a message which is sent to the receiver of the tagged electronic object along with its operation code. We begin by proposing a protocol for the system and perform a simulation to check the feasibility of this project before applying it to a real world scenario. In this simulation we test the capability of the transmitter and receiver to communicate effectively.

Bulk laundry monitoring system  

International Nuclear Information System (INIS)

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

Evaluation of Noise in Hearing Instruments Caused by GSM and DECT Mobile Telephones  

DEFF Research Database (Denmark)

The annoyance of noise in hearing instruments caused by electromagnetic interference from Global systems for Mobile Communication (GSM) and Digital European Cordless Telecommunication (DECT) mobile telephones has been subjectively evaluated by test subjects. The influence on speech recognition from the GSM and the DECT noises was also determined. The measurements involved seventeen hearing-imparied subjects. The annoyance was tested with GSM and DECT noise, each one mixed with continuous speech, a mall environment noise, or an office environment noise. Speech recognition was tested with the DANTALE word material mixed with GSM and DECT noise. The listening tests showed that if the noise level is acceptable so also is speech recognition. The results agree well with an investigation carried out on normal-hearing subjects. If a hearing instrument user is able to use a telephone without annoyance, the input-related noise level must not exceed 47 dB SPL for GSM and 46 dB SPL for DECT.

Integrated technologies for solid waste bin monitoring system.  

Science.gov (United States)

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

Eavesdropping on GSM: state-of-affairs  

CERN Document Server

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...

Uninterruptible power supply for GSM/UMTS base stations using fuel cells. PEM-FC back-up system - Final report; Unterbrechungsfreie Stromversorgung (USV) fuer GSM/UMTS-Basisstationen mit Brennstoffzellen. PEM-FC Back-Up System - Schlussbericht  

Energy Technology Data Exchange (ETDEWEB)

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)

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.

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. The project takes place in collaboration with the industrial partners APC Industrial Systems, as a producer and market leader of UPS-Systems, and Swisscom Mobile AG, as a user of UPS-systems in telecommunications. Following the good results and in order to get more experience in long-term operation of the Fuel Cell system the tests will go on for two more years. (author)

Nonlinear Filtering for Hybrid GPS/GSM Mobile Terminal Tracking  

Directory of Open Access Journals (Sweden)

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.

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

Energy Technology Data Exchange (ETDEWEB)

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

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

Transferring standards: lessons from GSM-R in the railway sector  

Digital Repository Infrastructure Vision for European Research (DRIVER)

In the mid 1990s the European railway community – under the aegis of the Union Internationale des Chemins de fer (UIC) – opted for GSM as the standard to replace existing analogue railway radio systems. The decision was taken on two grounds: GSM was a non-proprietary standard (i.e. open standard) and it fulfilled the needs of railway operators. Other arguments put forward to support the choice was that choosing GSM would have the advantage to remain close to the development of the publ...

SMS service from your GSM mobile phone  

CERN Document Server

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...

Plutonium process monitoring (PPM) system  

Science.gov (United States)

In mid-1980, Marsh and Pope developed an online gamma system to monitor americium, uranium and plutonium gamma rays during anion-exchange process for plutonium aqueous recovery operations. It has been shown that the real-time elution profiles of actinide impurities are important for plutonium loss via break-through, waste minimization, and process monitoring. However, the current monitoring equipment and data acquisition software are obsolete and are frequently problematic. In 1999, we redesigned the on-line gamma monitoring system in collaboration with Perkin-Elmer ORTEC (Oak Ridge, TN) to enhance and upgrade the current system. This paper describes the new integrated plutonium process monitoring (PPM) system for the aqueous plutonium recovery and anion-exchange processes at the Los Alamos Plutonium Facility. .

Flow cytometer jet monitor system  

Energy Technology Data Exchange (ETDEWEB)

A direct jet monitor illuminates the jet of a flow cytometer in a monitor wavelength band which is substantially separate from the substance wavelength band. When a laser is used to cause fluorescence of the substance, it may be appropriate to use an infrared source to illuminate the jet and thus optically monitor the conditions within the jet through a CCD camera or the like. This optical monitoring may be provided to some type of controller or feedback system which automatically changes either the horizontal location of the jet, the point at which droplet separation occurs, or some other condition within the jet in order to maintain optimum conditions. The direct jet monitor may be operated simultaneously with the substance property sensing and analysis system so that continuous monitoring may be achieved without interfering with the substance data gathering and may be configured so as to allow the front of the analysis or free fall area to be unobstructed during processing.

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

GSM. Columbia Plateau Geologic Site Simulation  

Energy Technology Data Exchange (ETDEWEB)

GSM is a Monte Carlo simulation program for tracking the future evolution of a repository site over periods of up to several million years. Phenomena included in the model that potentially can affect the site over such periods are: climatic changes, glaciation, deformation, geomorphic events, magmatic events, meteorite impact, sea-level fluctuations, shaft seal failure, basement faulting, and undetected features. Interrelationships among phenomena are modeled, and the effects of changes on ground-water flow are followed using a simplified network model of the ground-water system in a two-dimensional cross-section of the study area. The model is specific to a potential repository site in the Pasco Basin area of the Columbia Plateau. The ground water portion of the code is two-dimensional and is based on a specific conceptualization of the hydrology in the region surrounding the Pasco Basin. The probabilistic nature of the model enables it to be used to evaluate whether a potential site meets any probabilistic regulatory standards such as those that have been issued by the Environmental Protection Agency. Two auxiliary interactive programs to process input and output, respectively, are included. The Input Module is executed prior to the simulation to 1) generate a set of unformatted data files for first-time simulation access; 2) change any or all input parameter values from the previous simulation; or 3) generate listings of input parameter values. The Output Module is used to examine the three unformatted files (SUMMARY, HISTORY, and MASTER) produced by GSM. In addition, an auxiliary conversion routine is included to convert the formatted climate data to binary records for use by the Far Field State Model (FFSM) program .

SMS based Wireless Notice board with Monitoring system  

Directory of Open Access Journals (Sweden)

Full Text Available This project is designed using ARM-LPC2148 interfaced with Graphical Display. At present, when information has to be updated in a notice board, it has to be done manually. Also in present electronic systems, no matter how many displays are present, only a single notice can be sent to all of the notice boards irrespective of their places. In order to overcome this disadvantage, multiple displays along with a decoder are used to select a particular display and the corresponding information is sent through an ARM controller by using GSM technology. The entries can be documented and a record may be maintained for future use by using visual basic. The controller has internal a real time clock used for synchronization of data. A resistive touch screen is used to access the previous notices and also progress details. The monitoring system consists of an image sensor which captures the images for the specified amount of time and the images can be transferred through an USB port to a PC for storage purposes.

Fermilab distributed monitoring system (NGOP)  

International Nuclear Information System (INIS)

A Distributed Monitoring System (NGOP) that will scale to the anticipated requirements for Run II computing has been under development at Fermilab. NGOP [1] provides a framework to create Monitoring Agents for monitoring the overall state of computers and software that are running on them. Several Monitoring Agents are available within NGOP that are capable of analyzing log files, and checking existence of system daemons, CPU and memory utilization, etc. NGOP also provides customisable graphical hierarchical representations of these monitored systems. NGOP is able to generate events when serious problems have occurred as well as raising alarms when potential problems have been detected. NGOP allows performing corrective actions or sending notifications NGOP provides persistent storage for collected events, alarms and actions. A first implementation of NGOP was recently deployed at Fermilab. This is a fully functional prototype that satisfies most of the existing requirements. For the time being the NGOP prototype is monitoring 512 nodes. During the first few months of running NGOP has proved to be a useful tool. Multiple problems such as node resets, offline CPUs, and dead system daemons have been detected. NGOP provided system administrators with information required for better system tuning and configuration. The current state of deployment and future steps to improve the prototype and to implement some new features will be presented

Internet Access from CERN GSM subscriptions  

CERN Document Server

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

A Grid job monitoring system  

International Nuclear Information System (INIS)

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.

Structural Health Monitoring: Alarming System  

Directory of Open Access Journals (Sweden)

Full Text Available There is a huge investment in our infrastructure that is vital to our social and economic life. However, the aging and deterioration of the structures require implementing a damage detection system to monitor their structural integrity. In this study, a new alarming system was developed as part of a structural health monitoring system and installed in a scaled-down structure models. The designed system incorporated microprocessors, wireless communication, transducer, and cellular transmission that allow remote monitoring. The developed system facilitates continuous monitoring process of any part of structures and controlled remotely from any location. The system was equipped with data processing subsystem that detects structural behavior irregularity, defects, and potential failures. The system was tested using Linear Variable Differential Transformer (LVDT for deflections and using strain gages to measure the developed axial and flexural strains in different structural models. Filtering algorithm was used to filter graphs and the data gathered in each loading stage was averaged and plotted to show the abrupt change in the values. The filtering system helps the alarming system to have a clear prediction of possible irregularities. The developed system provides the desired features of low cost, low power, small size, flexibility and easy implementation, remote accessing, early detection of problems, and simplified representation of the results.

Monitoring the DIRAC distributed system  

CERN Document Server

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

A Novel Radiation Monitoring System  

International Nuclear Information System (INIS)

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

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)

GTA Beamloss-Monitor System  

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

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

Directory of Open Access Journals (Sweden)

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.

Comparison of grey scale median (GSM) measurement in ultrasound images of human carotid plaques using two different softwares.  

Science.gov (United States)

Grey scale median (GSM) measured on ultrasound images of carotid plaques has been used for several years now in research to find the vulnerable plaque. Centres have used different software and also different methods for GSM measurement. This has resulted in a wide range of GSM values and cut-off values for the detection of the vulnerable plaque. The aim of this study was to compare the values obtained with two different softwares, using different standardization methods, for the measurement of GSM on ultrasound images of carotid human plaques. GSM was measured with Adobe Photoshop(®) and with Artery Measurement System (AMS) on duplex ultrasound images of 100 consecutive medium- to large-sized carotid plaques of the Beta-blocker Cholesterol-lowering Asymptomatic Plaque Study (BCAPS). The mean values of GSM were 35·2 ± 19·3 and 55·8 ± 22·5 for Adobe Photoshop(®) and AMS, respectively. Mean difference was 20·45 (95% CI: 19·17-21·73). Although the absolute values of GSM differed, the agreement between the two measurements was good, correlation coefficient 0·95. A chi-square test revealed a kappa value of 0·68 when studying quartiles of GSM. The intra-observer variability was 1·9% for AMS and 2·5% for Adobe Photoshop. The difference between softwares and standardization methods must be taken into consideration when comparing studies. To avoid these problems, researcher should come to a consensus regarding software and standardization method for GSM measurement on ultrasound images of plaque in the arteries. PMID:23701450

Control rod withdrawal monitoring system  

International Nuclear Information System (INIS)

Purpose: To improve the responsivity of a control rod withdrawal monitoring system by judging the number of bypassed local power range monitors (LPRM) and amplifying the average value of the signals from the monitors based on the judged results in BWR type reactors. Constitution: The number of bypassed LPRM is judged by a bypass number judging circuit, and output signals from an averaging circuit that averages the signals from LPRM are amplified by a signal correction circuit. Thus, the output from the averaging circuit are amplified by so much in the signal correction circuit as the number of the bypassed LPRM increases. Degradation in the responsivity due to the bypassing of LPRM can thus be prevented, whereby erroneous withdrawal of the control rods, if should occur, during power operation can be inhibited always at an early position to prevent the powerup.

Corral Monitoring System assessment results  

International Nuclear Information System (INIS)

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

PC based vibration monitoring system  

International Nuclear Information System (INIS)

Health of large rotating machinery gets reflected in the vibration signature of the rotor and supporting structures and proper recording of these signals and their analysis can give a clear picture of the health of the machine. Using these data and their trending, it is possible to predict an impending trouble in the machine so that preventive action can be taken in time and catastrophic failure can be avoided. Continuous monitoring and analysis can give quick warning and enable operator to take preventive measures. Reactor Control Division, BARC is developing a PC based Vibration monitoring system for turbo generator machinery. The System can acquire 20 vibration signals at a rate of 5000 samples per second and also 15 process signals at a rate of 100 samples/ sec.

Operational benefits obtained by implementing a remote monitoring and control system at CEGAS (Gas Company of Ceara, Brazil)  

Energy Technology Data Exchange (ETDEWEB)

CEGAS (Gas Company of Ceara) recently implemented an automated remote monitoring and control system at the Natural Gas Stations located within the city of Fortaleza. The main purposes to implement the project were to install a better operational platform, allowing CEGAS to analyze its operational conditions and to measure customer's consumption in real time. The data communication infra-structure chosen was GPRS/GSM, due to it's low deployment cost and coverage availability. The first phase of the project comprised 50 vehicular natural gas stations. The project was successfully installed, and became the 1{sup st} project at this type to run efficiently over a GPRS infra-structure in Brazil for gas monitoring, with reliable control and data communication. This document intends to present the reasons that lead CEGAS to invest in such a system, the technology deployed and the benefits achieved. (author)

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

Efficient Radio Resource Allocation in a GSM and GPRS Cellular Network  

Directory of Open Access Journals (Sweden)

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.

Directory of Open Access Journals (Sweden)

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.

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

Science.gov (United States)

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

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

Directory of Open Access Journals (Sweden)

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.

A Novel Model for Optimized GSM Network Design  

CERN Multimedia

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

Monitored Geologic Repository Operations Monitoring and Control System Description Document  

Energy Technology Data Exchange (ETDEWEB)

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.

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.

Gaia basic angle monitoring system  

Science.gov (United States)

The Gaia mission1 will create an extraordinarily precise three-dimensional map of more than one billion stars in our Galaxy. The Gaia spacecraft2, built by EADS Astrium, is part of ESA's Cosmic Vision programme and scheduled for launch in 2013. Gaia measures the position, distance and motion of stars with an accuracy of 24 micro-arcsec using two telescopes at a fixed mutual angle of 106.5°, named the `Basic Angle', at an operational temperature of 100 K. This accuracy requires ultra-high stability at cryogenic conditions, which can only be achieved by using Silicon Carbide for both the optical bench and the telescopes. TNO has developed, built and space qualified the Silicon carbide Basic Angle Monitoring (BAM) on-board metrology system3 for this mission, measuring the relative motion of Gaia's telescopes with accuracies in the range of 0.5 micro-arcsec. This is achieved by a system of two laser interferometers able to detect Optical Path Differences (OPD) as small as 1.5 picometer rms. Following a general introduction on Gaia and the use of Silicon Carbide as base material this paper addresses the specific challenges towards the cryogenic application of the Gaia BAM including design, integration and verification/qualification by testing.

Operation and maintenance of the TFTR grounding system  

International Nuclear Information System (INIS)

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

Innovative portable radiation monitoring system  

Energy Technology Data Exchange (ETDEWEB)

A new generation of portable monitoring systems is presented. The system consists of RAM R-200, a portable gamma meter designed for measuring wide range gamma radiation fields, and external probes for beta-gamma contamination, and high range gamma fields. The meter and the external probes were designed to withstand vibrations, shocks and extreme temperature conditions. The meter is lightweight - less than 500 g, compact - 80 x 35 x 130 mm, with emphasis on ergonomic design and ease of operation. It contains an internal detector with two energy compensated GM tubes for gamma field measurement in the range of 0.1 {mu}Sv/h to 1 Sv/h, and flat energy response to gamma radiation from 60 keV to 1350 keV. Low power consumption techniques enable more than 100 hours of continuous operation with a single 9V standard battery. The meter and the high range gamma probe meet the IEC1017-1 and ANSI-N42 standards. The meter includes signal processing electronics and embedded microprocessor circuitry. Dedicated software for data processing was developed, enabling smoothed analog and digital readout and fast response. Additional functions include accumulated dose calculation, malfunction detection and appropriate alarm, dose rate and accumulated thresholds, serial RS-232 communication with the external probes or with a PC. The RAM R-200 supports the logging or dose-rate measurements and acquisition time into its internal backed-up memory. Due to the importance of the audible indication to the user of such system an intensive study was done. Two audible indication modes are available. A conventional mode based on a short 'chirp' every pulse measured and variable frequency mode according to the field intensity. In the latter mode the meter automatically normalizes the frequency response with the actual measured field. The meter and the external probes include an internal microcontroller circuitry, power supplies for the internal electronics and detector high voltage, and output signal processing electronics. Each one of the external probes can be operated either by connection to the meter or to a PC. This feature enables detector calibration and storage of calibration factors in the probes' nonvolatile memory, via serial communication to a PC. The meter automatically identifies each change of external probe. The internal detector accumulated dose is recorded in the meter also when measurement is performed by an external probe. A magnesium case for the meter is under development. This case will reduce about 20% of the meter weight and decrease 15% of the low energy gamma rays absorption compared to the aluminum case. A special telescopic rod was developed as an accessory for the system. This rod enables the reading of hard to reach areas and measurement of high activity sources, where a safety distance must be kept between the measurement point and the operator. The RAM R-200 system ease of operation, compact dimensions and extreme environmental conditions withstanding, makes it useful to a variety of applications such as: General purpose survey meter, portable or stand alone radiation measurement station, NPP radiation monitoring, Nuclear Medicine, beta gamma surface contamination detection and measurement.

Control system of environmental radiation monitoring  

International Nuclear Information System (INIS)

On the operation of nuclear power station, monitoring of environmental radiation by continuous measurement to ensure the health and safety of public is the responsibility of the operation side. Monitoring of environmental radiation covers various measurement. Among them, the continuous measurement of spatial ?-ray rate is thought to be an effective method because this measurement is possible to detect the fluctuation of the level of environmental radiation quickly and is effective to find out abnormal condition in early stage. The monitoring system of spatial ?-ray rate is composed of low range monitoring equipment and high range monitoring equipment, signal transmitting system and monitoring station. NaI(Tl) scintillator, which can measure the background radiation and the radiation from power station separately, is used for the former monitoring, and is able to identify the source of radiation. For the monitoring of high range radiation, pressurized spherical scintillator is used to catch the spatial ?-ray in the occasion of emergency. Those equipments were installed in stations of ALC plate construction, and signals are transmitted to monitoring center by optical fiber cable. The monitoring panel of monitoring center is equipped with output terminals making provisions for future computerization. Though present system is attaining high evaluation, efforts are being made to reach higher reliability by improving the signal transmitting system and by developing new materials for radiation detecting device.

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

How Many Smart Meters can be Deployed in a GSM cell?  

DEFF Research Database (Denmark)

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.

Intelligent monitoring system for intensive care units.  

Science.gov (United States)

We address in the present paper a medical monitoring system designed as a multi-agent based approach. Our system includes mainly numerous agents that act as correlated multi-agent sub-systems at the three layers of the whole monitoring infrastructure, to avoid non informative alarms and send effective alarms at time. The intelligence in the proposed monitoring system is provided by the use of time series technology. In fact, the capability of continuous learning of time series from the physiological variables allows the design of a system that monitors patients in real-time. Such system is a contrast to the classical threshold-based monitoring system actually present in the Intensive Care Units (ICUs) which causes a huge number of irrelevant alarms. PMID:21505862

Vibration Monitoring of Rotating Systems  

Directory of Open Access Journals (Sweden)

Full Text Available Most energy-conversion machines (e.g. vehicle engines and electric motors involve rotating components (e.g. roller bearings and gears, which generate vibrations. The behavior of a pump which includes a deliberate fault was chosen to illustrate this assertion. The test bearing at the driven end of the pump’s motor was deliberately damaged using a 1.5mm wire-cutting method and an adjustable coupling disk introduced to impose a shaft misalignment of 40. The resulting undesirable behavior of the pump was observed. Experimental data were measured at various speeds of the rotor. The sample period at various operating frequencies were 0.9, 0.6 and 0.45s respectively. The ball-passage frequency was observed at 4.4, 8.8, 13.2 and 17.6Hz. A computer-based analytical model was developed, in visual basic, for monitoring the machine failures: this led to an integrated system-process algorithm for diagnosis of faults in rotating components.

Automotive engine oil monitoring system  

Energy Technology Data Exchange (ETDEWEB)

This patent describes a system for continuously monitoring and indicating engine oil deterioration during the period of the oil's useful life in an internal combustion engine comprising: temperature signal generating a signal representative of engine oil temperature; deterioration rate measuring means coupled to the temperature signal generating means for determining the rate of deteriorating as a function of oil temperature; engine running time measuring means for generating a signal representative of elapsed engine running time; time measuring means for generating a signal representative of actual elapsed time since the oil was changed; a first remaining useful determining means coupled to the deterioration rate determining means and the engine running time measuring means for determining the first remaining useful life. This produces a continuous output signal representative of the first remaining useful life; a second remaining useful life determines means coupled to the deterioration rate and the time measuring means for determining the second remaining useful life of oil as a function producing a continuous output signal representative of the second remaining useful life; signal selecting means for selecting either the output signal from the first remaining useful life determining means or the output signal from the second remaining useful life determining means; and indicating means coupled to the remaining useful life determining means for indicating the remaining useful life as a function of the selected output signal.

DOWNHOLE VIBRATION MONITORING & CONTROL SYSTEM  

Energy Technology Data Exchange (ETDEWEB)

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.

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)

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.

Monitoring by holographic radar systems  

Science.gov (United States)

Nowadays, radar technology represents a significant opportunity to collect useful information for the monitoring and conservation of critical infrastructures. Radar systems exploit the non-invasive interaction between the matter and the electromagnetic waves at microwave frequencies. Such an interaction allows obtaining images of the region under test from which one can infer the presence of potential anomalies such as deformations, cracks, water infiltrations, etc. This information turns out to be of primary importance in practical scenarios where the probed structure is in a poor state of preservation and renovation works must be planned. In this framework, the aim of this contribution is to describe the potentialities of the holographic radar Rascan 4/4000, a holographic radar developed by Remote Sensing Laboratory of Bauman Moscow State Technical University, as a non-destructive diagnostic tool capable to provide, in real-time, high resolution subsurface images of the sounded structure [1]. This radar provides holograms of hidden anomalies from the amplitude of the interference signal arising between the backscattered signal and a reference signal. The performance of the holographic radar is appraised by means of several experiments. Preliminary tests concerning the imaging below the floor and inside wood structures are carried out in controlled conditions at the Electromagnetic Diagnostic Laboratory of IREA-CNR. After, with reference to bridge monitoring for security aim, the results of a measurement campaign performed on the Musmeci bridge are presented [2].

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.)

NASA Carbon Monitoring System Program  

Science.gov (United States)

NASA has recently begun a focused program to provide products on the amount and distribution of carbon reservoirs and fluxes in the global environment informed by the increasing global observational capability for these quantities developed by NASA and its interagency and international partners. This program, known as a Carbon Monitoring System (CMS), serves as a user-responsive, product-oriented overlay onto the existing observational, modeling, and research programs sponsored by NASA's Earth Science Division (ESD). Initial emphasis is on two pilot products - one on terrestrial biomass and one on integrated emission/uptake ("flux"), as well as a "scoping study" that will enable longer-term planning built around the increasing global observational capability NASA expects to be launching in the next few years (e.g., Landsat Data Continuity Mission in 2012, reflight of Orbiting Carbon Observatory in 2013, decadal survey missions including ICESat-II in 2015 and DESDynI in 2017). Initial efforts on the pilot products are based largely at three NASA centers (Ames, Goddard, Jet Propulsion Laboratory), but will draw on the broader expertise of the research community through workshops (e.g., one held in Boulder in July, 2010) as well as a planned solicitation for a Science Definition Team to provide broader guidance into the development, evaluation, and future evolution of the pilot products. The NASA CMS activity, with its emphasis on utilization of NASA remote-sensing data, will complement related efforts of other Federal agencies; coordination with other agencies will be carried out through the US Global Change Research Program. In this talk, steps taken to initiate this activity in FY2010 and plans for its evolution into the future will be presented.

In-vitro exposure of neuronal networks to the GSM-1800 signal.  

Science.gov (United States)

The central nervous system is the most likely target of mobile telephony radiofrequency (RF) field exposure in terms of biological effects. Several electroencephalography (EEG) studies have reported variations in the alpha-band power spectrum during and/or after RF exposure, in resting EEG and during sleep. In this context, the observation of the spontaneous electrical activity of neuronal networks under RF exposure can be an efficient tool to detect the occurrence of low-level RF effects on the nervous system. Our research group has developed a dedicated experimental setup in the GHz range for the simultaneous exposure of neuronal networks and monitoring of electrical activity. A transverse electromagnetic (TEM) cell was used to expose the neuronal networks to GSM-1800 signals at a SAR level of 3.2 W/kg. Recording of the neuronal electrical activity and detection of the extracellular spikes and bursts under exposure were performed using microelectrode arrays (MEAs). This work provides the proof of feasibility and preliminary results of the integrated investigation regarding exposure setup, culture of the neuronal network, recording of the electrical activity, and analysis of the signals obtained under RF exposure. In this pilot study on 16 cultures, there was a 30% reversible decrease in firing rate (FR) and bursting rate (BR) during a 3 min exposure to RF. Additional experiments are needed to further characterize this effect. PMID:23913345

Centralized environmental radiation monitoring system in JAERI  

International Nuclear Information System (INIS)

JAERI has continued the environmental radiation background survey and monitoring to ensure the safety of the peoples around the institute since one year before the first criticality of JRR-1 (Japan Research Reactor No.1) in August 1957. Air absorbed doses from ? and ? radiation, ? and ? radioactivity in air and the radioactivities in environmental samples were the monitoring items. For the monitoring of ? and ? radiation and ? and ? radioactivity in air, monitoring station and the centralized automatic environmental radiation monitoring system applying a computer were established as a new challenging monitoring system for nuclear facility, which was the first one not only in Japan but also in the would in 1960 and since then the system has been renewed two times (in 1973 and 1988) by introducing the latest technology in the fields of radiation detection and computer control at each stage. 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 arisen from 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

Plataforma para servicios de valor agregado basados en localización, en una red gsm, a partir de la medición de la intensidad de seńal (Parte I).  

Scientific Electronic Library Online (English)

Full Text Available SciELO Venezuela | Language: Spanish Abstract in spanish 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 seńal, 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.

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.

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.

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

Upgrade of the LHCb ECAL monitoring system  

CERN Document Server

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.

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)

Image detection monitoring system (IDMS) for landslide monitoring  

Science.gov (United States)

In the field of topographic displacement monitoring systems, the CNR IRPI of Turin has developed and patented a new instrumentation, named Image Detection For Monitoring System (IDMS). The IDMS is constituted by a digital reflex camera that, according to different needs, can be combined to a long range reflectorless laser distantiometer . The resulting assembly is automatically moved by an high accuracy sophisticated positioning mechanism managed by a low-consumption pc. The principle of operation is based on the analysis of a time series of pictures of an area that, processed using particular algorithms, allow to obtain topographic displacements. If necessary, with the long range laser integration it is also possible to get the displacement values in three-dimensions. The system, initially experimented with the use of a cam, has been improved using a reflex camera, developing a special software that allowed to improve performances and to set algorithms to seek the monitored areas. These implementations, in addition to the freedom from the needs of reflecting targets, increase the system flexibility that can operate in dynamic contexts where the phenomenon morphology can quickly change. With this characteristics , the IDMS can preserve the topographic total station accuracy, but it hasn't the necessity to use expensive reflecting targets, often characterized by the difficulty of their installation and maintenance. These characteristics make the system most flexible allowing to modify the investigated areas without particular logistic difficulties and without further costs.

Quaternion Based Omnidirectional Machine Condition Monitoring System  

Directory of Open Access Journals (Sweden)

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%

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

The Lower Saxony reactor remote monitoring system  

International Nuclear Information System (INIS)

Remote monitoring of nuclear power plants has been demanded by the German Federal Parliament for all nuclear power stations in the country. The Federal States are responsible for the practical implementation of this requirement, which means that measuring and monitoring centers are assigned to the respective Federal States. The first nuclear reactor remote monitoring system has been in operation in Bavaria since 1979. The State of Lower Saxony is the second state to install for its nuclear power plants a reactor remote monitoring system. Remote monitoring does not replace the local control installations covering all systems of a nuclear power plant, nor does it overrule the existing duty of the operator to report any accidents or incidents. Instead, it supplements this plant control in order to ensure even more thorough control of operation and of emissions. The data collected from the measuring stations in a nuclear power plant are transmitted hourly by public telephone line from a subcenter on the reactor site to a state measuring center controlled by a process computer, where they are recorded and checked. If the data transmitted were to approach permissible limits, the remote monitoring system would automatically change over to ten-minute scans. When limits are reached, an alarm is actuated automatically. The remote monitoring function not only serves as a means of double checking, but also to dissipate reservations against nuclear power plants in the mind of the public. (orig.)

Monitoring of LWR component cooling water systems  

International Nuclear Information System (INIS)

As part of the Nuclear Plant Aging Research program, the monitoring methods used for component cooling water (CCW) systems in pressurized water reactors (PWRs) were reviewed and evaluated in terms of their effectiveness at detecting various aging mechanisms. A survey of PWRs was performed to determine what practices are currently used. Monitoring methods for three of the major components in the CCW system were correlated with the aging mechanisms they are able to detect, and generic tables of practices were developed. These tables can be used by utilities to strengthen their monitoring program once specific aging concerns have been identified. 1 ref., 2 figs., 5 tabs

The CMS ECAL Laser Monitoring System  

CERN Document Server

Light monitoring will play a crucial role in maintaining the energy resolution of the CMS electromagnetic calorimeter, by providing transparency corrections for its 75,848 lead tungstate (PbWO4) crystals. To maintain the resolution of the calorimeter, the variation in the light output of the PbWO4 crystals in the harsh radiation environment of the LHC is corrected for by using a light monitoring system. The design of the light monitoring system, as well as the performance during test beams, is discussed.

Monitoring the CMS data acquisition system  

International Nuclear Information System (INIS)

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 collections. An implementation following this scheme is deployed as the monitoring infrastructure of the CMS experiment at the Large Hadron Collider. All services in this distributed data acquisition system are providing standard web service interfaces via XML, SOAP and HTTP. Continuing on this path we adopted WS-* standards implementing a monitoring system layered on top of the W3C standards stack. We designed a load-balanced publisher/subscriber system with the ability to include high-speed protocols for efficient data transmission and serving data in multiple data formats.

Configuration of risk monitor system by plant defense-in-depth risk monitor and reliability monitor  

International Nuclear Information System (INIS)

A new method of risk monitor system of a nuclear power plant has been proposed from the aspect by what degree of safety functions incorporated in the plant system is maintained by multiple barriers of defense-in-depth (DiD). Wherein, the central idea is plant DiD risk monitor and reliability monitor derived from the five aspects of (1) design principle of nuclear safety based on DiD concept, (2) definition of risk and risk to be monitored, (3) severe accident phenomena as major risk, (4) scheme of risk ranking, and (5) dynamic risk display. In this paper, the overall frame of the proposed risk monitor system is summarized and the detailed discussion is made on major items such as definition of risk and risk ranking, anatomy of fault occurrence, two-layer configuration of risk monitor, how to configure individual elements of plant DiD risk monitor, and lastly how to apply for a PWR safety system.

Achieving a "SIL 1" TCR Monitoring System  

CERN Document Server

SIL 1 (Safety Integrity Level 1) refers to the quantification and measurement of the availability, reliability, maintenance and safety of the monitoring system. In the last few years the computer infrastructure used to acquire and to diffuse data to the TCR has evolved very rapidly. A number of measures in hardware, software and management have been introduced to cope with this situation. These include: the Multipurpose Monitoring Device (MMD), a standard data acquisition platform used in the renovation of old front end monitoring equipment, the Smart Equipment Controller (Dsec), a driver that reduces the layers in the data diffusion pyramid, the multiplatform monitoring software to integrate the different SCADA systems, a software configuration tool (RAZOR) for problem tracking and version control, and a complete development environment reproducing a real installation for thorough testing of any changes. To achieve SIL 1 objectives, while mastering the evolution of our systems will be the challenge for the c...

The SSRL injector beam position monitoring systems  

International Nuclear Information System (INIS)

The beam position monitoring system of the SSRL injector forms a vital component of its operation. Several different types of instrumentation are used to measure the position or intensity of the electron beam in the injector. These include current toroids, fluorescent screens, Faraday cups, the 'Q' meter, a synchrotron light monitor, and electron beam position monitors. This paper focuses on the use of the electron beam position monitors to measure electron trajectories in the injector transport lines and the booster ring. The design of the beam position monitors is described in another paper to be presented at this conference. There are three different beam position monitor systems in the injector. One system consists of a set of five BPMs located on the injection transport line from the linac to the booster (known as the LTB line). There is a second system of six BPMs located on the ejection transport line (known as the BTS line). Finally, there is an array of 40 BPMs installed on the main booster ring itself. This article describes the software and processing electronics of the systems used to measure electron beam trajectories for the new SSRL injector for SPEAR

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.

Computerized plutonium laboratory-stack monitoring system  

International Nuclear Information System (INIS)

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

Acoustic emission monitoring of composite containment systems  

Energy Technology Data Exchange (ETDEWEB)

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

Nonlinear heart rate variability measures under electromagnetic fields produced by GSM cellular phones.  

Science.gov (United States)

This study was designed to assess the nonlinear dynamics of heart rate variability (HRV) during exposure to low-intensity EMFs. Twenty-six healthy young volunteers were subjected to a rest-to-stand protocol to evaluate autonomic nervous system in quiet condition (rest, vagal prevalence) and after a sympathetic activation (stand). The procedure was conducted twice in a double-blind design: once with a genuine EMFs exposure (GSM cellular phone at 900 MHz, 2 W) and once with a sham exposure (at least 24 h apart). During each session, three-lead electrocardiograms were recorded and RR series extracted off-line. The RR series were analyzed by nonlinear deterministic techniques in every phase of the protocol and during the different exposures. The analysis of the data shows there was no statistically significant effect due to GSM exposure on the nonlinear dynamics of HRV. PMID:23675620

Control rod withdrawal monitoring system  

International Nuclear Information System (INIS)

Purpose: To prevent excessively rapid power up caused by the control rod withdrawal upon high power operation. Constitution: In a BWR type reactor, are provided control rod drives adapted to withdrawing the control rod stepwise for the plurality of steps set to the entire stroke, and an inspection device adapted to inhibit the simultaneous withdrawal of the control rod for the plurality of stages but allow only the stepwise withdrawal if the reactor power exceeds a limiting value set between about 70 - 85% rated power. The reactor power is compared with the limiting value based on a reactor core power signal outputted from average power monitors to output a control rod continuous withdrawal inhibit signal for allowing notch-by-notch withdrawal of the control rod if the reactor power is greater than the limiting value and issue a continuous withdrawal enable signal if it is smaller than the limiting value. This enables to prevent excess power up in the high power operation. (Furukawa, Y.)

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.

Amplified OTDR systems for multipoint corrosion monitoring.  

Science.gov (United States)

We present two configurations of an amplified fiber-optic-based corrosion sensor using the optical time domain reflectometry (OTDR) technique as the interrogation method. The sensor system is multipoint, self-referenced, has no moving parts and can measure the corrosion rate several kilometers away from the OTDR equipment. The first OTDR monitoring system employs a remotely pumped in-line EDFA and it is used to evaluate the increase in system reach compared to a non-amplified configuration. The other amplified monitoring system uses an EDFA in booster configuration and we perform corrosion measurements and evaluations of system sensitivity to amplifier gain variations. Our experimental results obtained under controlled laboratory conditions show the advantages of the amplified system in terms of longer system reach with better spatial resolution, and also that the corrosion measurements obtained from our system are not sensitive to 3 dB gain variations.

Tritium monitor and collection system  

Science.gov (United States)

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

An Efficient Network Monitoring and Management System  

Directory of Open Access Journals (Sweden)

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.

Hydro-information system for drought monitoring  

Directory of Open Access Journals (Sweden)

Full Text Available Drought is a natural hazard caused by the variability in climate, which cannot be prevented. However, its effects can be reduced through management systems incorporating drought monitoring. The main aim of this paper is the presentation of information system for monitoring drought warning based on the model with optimal set of hydro-meteorological parameters: minimal number, availability of gauge data and spatial distribution of measuring locations. Monitoring the relevant hydro-meteorological parameters and creation of suitable forecast tools within a hydro-information system for monitoring drought warning would serve as a platform for decision making in drought effects reduction. Significance of this idea is in the substitution of complex climatological models. It requires time and maintenance investments with a practical method for estimation of drought duration and intensity which will satisfy the users' needs and will not require considerable economic investment.

LHCb: Monitoring the DIRAC Distribution System  

CERN Multimedia

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 ...

Continuous Glucose Monitoring Systems: A Review  

Directory of Open Access Journals (Sweden)

Full Text Available There have been continuous advances in the field of glucose monitoring during the last four decades, which have led to the development of highly evolved blood glucose meters, non-invasive glucose monitoring (NGM devices and continuous glucose monitoring systems (CGMS. Glucose monitoring is an integral part of diabetes management, and the maintenance of physiological blood glucose concentration is the only way for a diabetic to avoid life-threatening diabetic complications. CGMS have led to tremendous improvements in diabetic management, as shown by the significant lowering of glycated hemoglobin (HbA1c in adults with type I diabetes. Most of the CGMS have been minimally-invasive, although the more recent ones are based on NGM techniques. This manuscript reviews the advances in CGMS for diabetes management along with the future prospects and the challenges involved.

Assessment of extremely low frequency magnetic field exposure from GSM mobile phones.  

Science.gov (United States)

Although radio frequency (RF) electromagnetic fields emitted by mobile phones have received much attention, relatively little is known about the extremely low frequency (ELF) magnetic fields emitted by phones. This paper summarises ELF magnetic flux density measurements on global system for mobile communications (GSM) mobile phones, conducted as part of the MOBI-KIDS epidemiological study. The main challenge is to identify a small number of generic phone models that can be used to classify the ELF exposure for the different phones reported in the study. Two-dimensional magnetic flux density measurements were performed on 47 GSM mobile phones at a distance of 25?mm. Maximum resultant magnetic flux density values at 217?Hz had a geometric mean of 221 (+198/-104)?nT. Taking into account harmonic data, measurements suggest that mobile phones could make a substantial contribution to ELF exposure in the general population. The maximum values and easily available variables were poorly correlated. However, three groups could be defined on the basis of field pattern indicating that manufacturers and shapes of mobile phones may be the important parameters linked to the spatial characteristics of the magnetic field, and the categorization of ELF magnetic field exposure for GSM phones in the MOBI-KIDS study may be achievable on the basis of a small number of representative phones. Such categorization would result in a twofold exposure gradient between high and low exposure based on type of phone used, although there was overlap in the grouping. PMID:24203762

Hanger-type laundry monitor system  

International Nuclear Information System (INIS)

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

National Satellite Forest Monitoring systems for REDD+  

Science.gov (United States)

Reducing Emissions from Deforestation and Forest Degradation (REDD) is an effort to create a financial value for the carbon stored in forests, offering incentives for developing countries to reduce emissions from forested lands and invest in low-carbon paths to sustainable development. "REDD+" goes beyond deforestation and forest degradation, and includes the role of conservation, sustainable management of forests and enhancement of forest carbon stocks. In the framework of getting countries ready for REDD+, the UN-REDD Programme assists developing countries to prepare and implement national REDD+ strategies. For the monitoring, reporting and verification, FAO supports the countries to develop national satellite forest monitoring systems that allow for credible measurement, reporting and verification (MRV) of REDD+ activities. These are among the most critical elements for the successful implementation of any REDD+ mechanism. The UN-REDD Programme through a joint effort of FAO and Brazil's National Space Agency, INPE, is supporting countries to develop cost- effective, robust and compatible national monitoring and MRV systems, providing tools, methodologies, training and knowledge sharing that help countries to strengthen their technical and institutional capacity for effective MRV systems. To develop strong nationally-owned forest monitoring systems, technical and institutional capacity building is key. The UN-REDD Programme, through FAO, has taken on intensive training together with INPE, and has provided technical help and assistance for in-country training and implementation for national satellite forest monitoring. The goal of the support to UN-REDD pilot countries in this capacity building effort is the training of technical forest people and IT persons from interested REDD+ countries, and to set- up the national satellite forest monitoring systems. The Brazilian forest monitoring system, TerraAmazon, which is used as a basis for this initiative, allows countries to adapt it to country needs and the training on the TerraAmazon system is a tool to enhance existing capacity on carbon monitoring systems. The support with the National Forest Monitoring System will allow these countries to follow all actions related to the implementation of its national REDD+ policies and measures. The monitoring system will work as a platform to obtain information on their REDD+ results and actions, related directly or indirectly to national REDD+ strategies and may also include actions unrelated to carbon assessment, such as forest law enforcement. With the technical assistance of FAO, INPE and other stakeholders, the countries will set up an autonomous operational forest monitoring system. An initial version and the methodologies of the system for DRC and PNG has been launched in Durban, South Africa during COP 17 and in 2012 Paraguay, Viet Nam and Zambia will be launched in Doha, Qatar at COP 18. The access to high-quality satellite data for these countries is crucial for the set-up.

Energy Technology Data Exchange (ETDEWEB)

Complex special nuclear material (SNM) storage systems can benefit from automated monitoring and data integration systems that maximize safety and security and optimize system maintainability. Current methods of verification, which rely on physical access, are costly and labor intensive. A prototype data analysis. system for nuclear material monitoring is being developed through a joint effort by Argonne National Laboratory (ANL) and Lockheed Martin Idaho Technologies Company (LMITCO). The system synthesizes information from various sources and applies advanced data analysis to predict sensor faults and detect material instabilities and security/safeguards problems. The system makes use of Argonne's Multivariate State Estimation Technique, or MSET, to provide an early warning system for the performance of sensors and processes, The system is being implemented and tested at the Safeguard Technology Evaluation Laboratory (STEL) at ANL-W. The STEL was installed at a Fuel Manufacturing Facility (FMF) special nuclear materials vault at ANL-W in 1997 as part of a DOE Plutonium Focus Area Project. The STEL provides the infrastructure for the demonstration and integration of technologies for monitoring plutonium-bearing materials in various storage configurations. Real sensors located within the STEL are being used to ''calibrate'' and validate. software while simulated sensors are used to mockup larger-scale problems. Preliminary system design and testing results are discussed.

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

The report discusses design considerations of thermoluminescent dosimetry (TLD) badge for measurement of X and ?;, ? personnel exposures, a filter combination to compensate for energy dependence of the TLD disc and angular dependence of the badge. The badge reader incorporates a semiautomatic mechanical arrangement wherein the TLD cards are read, raising the heater after positioning the TLD discs one by one. Various figures illustrate the mechanical layouts and electronics circuits used in the system. Periodic quality assurance check of the system which ensures a good reproducibility, is also described.

An interactive beam position monitor system simulator  

Energy Technology Data Exchange (ETDEWEB)

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