CERN GSM monitoring system  

CERN Multimedia

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.

Directory of Open Access Journals (Sweden)

Full Text Available Global System for Mobile Communication (GSM) is a digital system developed to meet the desires of the entire public. As the population of a particular area, city or country increases, the number of mobile subscribers increases too. GSM network operators have to reduce congestion on their networks in order to satisfy their subscribers, therefore, a means of monitoring the base stations' locations and the geographical area of where they are located are important factor to achieve this purpose. This work provides a simple step-by-step approach on how to monitor the location of the base stations. A review of GSM and Global Positioning System (GPS) technology and their applications to the Geographic Information System (GIS) are presented. The means of taken the coordinates of base stations using a GPS device is also presented. ESRI's ArcView application software was used to design the map that shows the location of the base station and thereafter was integrated into the web. It concluded with the recommendation to GSM operators in Nigeria. If the recommendations are given necessary attention, the planning and optimization of cell sites will be enhanced and thereby reduce congestion on network. As a result, the performance of Network will improve, and it will give rise to subscribers' satisfaction and increasing profit returns to the operators.

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

GSM Based Smart Distribution System  

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)

Directory of Open Access Journals (Sweden)

Full Text Available A vehicle tracking system is an electronic device installed in a vehicle to enable the owner or a third party to track the vehicle's location. This paper proposed to design a vehicle tracking system that works using GPS and GSM technology, which would be the cheapest source of vehicle tracking and it would work as anti-theft system. It is an embedded system which is used for tracking and positioning of any vehicle by using Global Positioning System (GPS) and Global system for mobile communication (GSM). This design will continuously monitor a moving Vehicle and report the status of the Vehicle on demand. For doing so an AT89C51 microcontroller is interfaced serially to a GSM Modem and GPS Receiver. A GSM modem is used to send the position (Latitude and Longitude) of the vehicle from a remote place. The GPS modem will continuously give the data i.e. the latitude and longitude indicating the position of the vehicle. The same data is sent to the mobile at the other end from where the position of the vehicle is demanded. When the request by user is sent to the number at the GSM modem, the system automatically sends a return reply to that mobile indicating the position of the vehicle in terms of latitude and longitude in real time.

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)

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.

Directory of Open Access Journals (Sweden)

Full Text Available This paper basically describes how fuel level in fuel tanks can remotely be controlled and monitored in order to provide a cost-effective solution to a unique challenge of fuel shortage. This was experimented with the aid of Aplicom 12 GSM Module connected to a fuel gauge of a remote tank and the variation in fuel level was remotely monitored through a compatible mobile phone. Aplicom 12 Configurator software was used to configure the Aplicom 12 GSM Module. Then, control messages were sent from a compatible mobile phone through a GSM network to the Module and response messages were sent back to the mobile phone in form of different voltage levels which correspond to the volumes of fuel in the remote tank. An equation and a graph that relates volume to voltage were established.

Outage Probability in GSM-GPRS Cellular Systems with and  

UK PubMed Central (United Kingdom)

this paper, wepresent a method to calculate the outage probability of the GSM-GPRS network for both thenon-frequency hopping and the frequency hopping systems. This method takes into accountthe Rayleigh fading, power control (with error), discontinuous transmission, and frequencyhopping (if applied). The outage probability of voice services affected by the introduction ofGPRS is discussed. The number of unused voice channels allocated to GPRS depends on thedifference between the outage level of the existing GSM network and the maximumacceptable level. The frequency hopping system can accommodate more GPRS traffic than thenon-frequency hopping system. The power control error has more impact on the systemperformance when more channels are allocated to GPRS. Beyond our expectations, for thenon-frequency hopping system, the channels provided to GPRS are not much differentbetween the high channel occupancy and low channel occupancy of voice services. However,for the frequency hopping system, the system can provide more channels to GPRS at lowchannel occupancy. The cell service area decreases by about 10%~20% for each additionalchannel allocated to GPRS

VEHICLE THEFT ALERT SYSTEM USING GSM  

Directory of Open Access Journals (Sweden)

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

PREPAID ELECTRICITY BILLING SYSTEM USING GSM MOBILE  

Directory of Open Access Journals (Sweden)

Full Text Available The billing process of electricity consumption which we are using at present is very long process and requires lot of man power. The energy billing in India is error prone and also time and labor consuming. Errors get introduced at every stage of energy billing like errors with electro-mechanical meters, human errors while noting down the meter reading and error while processing the paid bills and the due bills. There are many cases where the bill is paid and then is shown as a due amount in the next bill. There is no proper way to know the consumer's maximum demand, usage details, losses in the lines, and power theft.For overcoming all the difficulties present in the system we are introducing fully automated billing process. In the proposed system front end is user friendly and can be operated easily by having minimum computer knowledge. The billing process is prepaid energy billing, which could be titled. Pay first and then use it. There are clear results from many countries, where prepaid system has reduced the wastage by a large amount. Another advantage of the prepaid system is that the human errors made reading meters and processing bills can be reduced to a large extent.

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.

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

Directory of Open Access Journals (Sweden)

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

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.

GSM BASED POWER METER READING AND CONTROL SYSTEM  

Directory of Open Access Journals (Sweden)

Full Text Available The present system of energy billing is error prone and also time and labor consuming. Errors get introduced at every stage of energy billing like errors with electro-mechanical meters, human errors while noting down the meter reading, and errors while processing the paid bills and the due bills. The home appliances which consume more power causes an increase in the payment of excessive bills. The remedy for all these problems GPMC(GSM based power meter and control system) is developed which consist of the integration of a single phase Class 1, IEC61036 , standard compliance digital kWh power meter. It will keep track of the meter reading of each day and the reading with the user identification number send it to the user as well as to the electricity department and Electricity eBilling system associated with electricity department will keep the track of each SMS meter reading and the appropriate bill get generated at the last day of the month and the bill is forwarded to user from the server. So there is no chances of confusion to the user for paying the bill. The GPMC also feature distribution control system which controls the power of the appliances remotely.

A Comprehensive Study and Performance Evaluation of Operational GSM and GPRS Systems under Varying Traffic Conditions  

UK PubMed Central (United Kingdom)

In the light of the introduction of 3G systems, wepresent a comprehensive study of the performance ofGSM and GPRS. UMTS is already in a few countriesdeployed, on the other hand it is expected that it will belimited to hot-spot areas, while voice calls will bepreferably established with existing networks. At theearly 80's, when GSM was introduced it was consideredas an overspecified system. Nowadays it is obvious thatthe whole range of services is used and in additionperformance is degreasing, due to the rapidly increasednumber of mobile subscribers. We strongly believe thatGSM is not yet optimized and this is a motivation totrigger new research topics in this area.

Medical reliable network using concatenated channel codes through GSM network.  

UK PubMed Central (United Kingdom)

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.

Energy Technology Data Exchange (ETDEWEB)

This paper gives the design idea of optimized PV-Solar and Wind Hybrid Energy System for GSM/CDMA type mobile base station over conventional diesel generator for a particular site in central India (Bhopal). For this hybrid system ,the meteorological data of Solar Insolation, hourly wind speed, are taken for Bhopal-Central India (Longitude 77 deg.23'and Latitude 23 deg.21' ) and the pattern of load consumption of mobile base station are studied and suitably modeled for optimization of the hybrid energy system using HOMER software. The simulation and optimization result gives the best optimized sizing of wind turbine and solar array with diesel generator for particular GSM/CDMA type mobile telephony base station. This system is more cost effective and environmental friendly over the conventional diesel generator. It should reduced approximate 70%-80% fuel cost over conventional diesel generator and also reduced the emission of CO2 and other harmful gasses in environments. It is expected that the newly developed and installed system will provide very good opportunities for telecom sector in near future.

Evolution of GSM  

Directory of Open Access Journals (Sweden)

Full Text Available GSM is the most widely deployed 2nd generation digital cellular standard, with over 2 billion subscribers in some 213 countries and adding about 1000 new users per minute! Originally developed in the 1980s, and first deployed in 1991, GSM is a TDMA+FDMA system, providing wide area voice communications using 200 KHz carriers. Subsequently, GSM evolved into a 2.5G standard with the introduction of packet data transmission technology (GPRS) and higher data rates via higher order modulation schemes (EDGE). More recently, GERAN standards organization has been evolving further to coexist with and provide comparable services to 3G technologies. In this paper, we provide an over view of evolution of GSM technology and also the framework of 4G technology that will provide access to wide range of telecommunication services, including advanced mobile services, supported by mobile and fixed networks, which are increasingly packet based, along with a support for low to high mobility applications and wide range of data rates, in accordance with service demands in multiuser environment.

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.

Effects of Mobile Phone System (GSM-900) on the Rabbit Hearing with Auditory Brainstem Response  

Directory of Open Access Journals (Sweden)

Full Text Available A rapid worldwide expansion of mobile telephones raises questions regarding possible effects of the emitted radiofrequencies on the health of the consumers. The mobile phone system (GSM-900) works in the range of 890-960 MHZ in the electromagnetic spectrum. The present study was performed to investigate the effect of mobile phone radiation on auditory system of rabbit. The auditory brainstem response (ABR), was studied before and after using a mobile phone in the hearing of rabbit. After measuring of click and tone burst at different frequencies (500, 1000, 2000, 4000 and 8000 HZ) with two intensities of 70 and 100 dB, the animals were exposured to electromagnetic waves from a simulator of mobile phone one week exposure and 16-19 h rest. The ABR tests were shown that the latency time of wave V (ms) have some changes in the frequencies of the experiments. The latency time of wave V (ms) at the frequencies of 500 and 1000 HZ was almost unchanged, but at the frequencies of 2000, 4000 and 8000 HZ were decreased at the end of second week of exposure. Statistical analysis have not any significant changes between time latency of wave in pre and post exposures.

GSM Security Using Identity-based Cryptography  

CERN Document Server

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

A fault detection monitoring system is described in this patent, suitable for industrial plants. One application of this invention could be the detection of fault conditions in nuclear reactors. A test signal device generates signals which are then superimposed on data signals from the plant being monitored so as to create a recognisable pattern of acceptable and unacceptable signals. As long as the expected pattern is received the correct operation of the plant and the monitoring system is assured. Because the device is coupled dynamically to pulse-coded logic (PCL) guardlines, it operates at a much higher frequency than arrays generated from status signals alone. (UK).

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)

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.

Review on Monitoring Systems of the Road Network  

Directory of Open Access Journals (Sweden)

Full Text Available The network monitoring is a way to detect quickly and effectively all problems having an impact on the road network and to evaluate them in a structured way. It also helps to allocate resources on the basis of priority in order to address, in timely, the urgent situations and to secure the road to protect other users that could potentially be affected by an incident. Generally, this type of service allowsessentially the location of people in distress and need assistance. This paper presents a review and synthesis of current knowledge on geolocation systems, used in the context of the monitoring of the roadnetwork, such as emergency call network, embedded system in vehicles and video cameras. We also present our new approach for an intelligent system of management of road safety; this system is acombination of GSM, GPS and Web-GIS to provide an ideal environment for the conception and test of an intelligent surveillance system in real time.

A Comparative Study of Three TDMA Digital Cellular Mobile Systems (GSM, IS-136 NA-TDMA and PDC) Based On Radio Aspect  

Directory of Open Access Journals (Sweden)

Full Text Available As mobile and personal communication services and networks involve providing seamless global roaming and improve quality of service to its users, the role of such network for numbering and identification and quality of service will become increasingly important, and well defined. All these will enhance performance for the present as well as future mobile and personal communication network, provide national management function in mobile communication network and provide national and international roaming. Moreover, these require standardized subscriber and identities. To meet these demands, mobile computing would use standard networks. Thus, in this study the researcher attempts to highlight a comparative picture of the three standard digital cellular mobile communication systems: (i) Global System for Mobile (GSM) -- The European Time Division Multiple Access (TDMA) Digital Cellular Standard, (ii) Interim Standard-136 (IS-136) -- The North American TDMA Digital Cellular Standard (D-AMPS), and (iii) Personal Digital Cellular (PDC) -- The Japanese TDMA Digital Cellular Standard.

Distributed System Contract Monitoring  

Directory of Open Access Journals (Sweden)

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

Safety system status monitoring  

Energy Technology Data Exchange (ETDEWEB)

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

Embedded linux for web monitoring of PV-diesel hybrid system for remote area power supply  

Energy Technology Data Exchange (ETDEWEB)

The autonomous PV-diesel hybrid system power supply is used world wide to supply electricity in rural areas where no grid, no telephone line coverage, and often difficult accessibility. Commonly, systems in such rural areas are supervised by yearly visits in conjunction with a data logger. Over the lifetime of a system, the costs for supervision often significantly exceed the cost of the system itself. Response time for maintenance, repair and product improvements is poor. To overcome these disadvantages, this project uses an embedded Linux system with an interactive web server. It is a small embedded Linux module for an Apache server with an extremely low power input required. The embedded module provides a common web server and data acquisition unit. The monitoring database can be stored in the web server and connected to a work station by a GSM modem. The communication will be base upon GSM technology. The monitoring database can be accessed via a standard web browser. When accessing the website, the operator can download monitored data as well as upload important parameters to the hybrid system inverters. Using embedded web base technology, the monitoring investment is very low-both initial costs and running costs. Development of monitoring system can improve the reliability of the system and can provoke more public interest in PV-diesel hybrid systems. (orig.)

System health monitoring  

Energy Technology Data Exchange (ETDEWEB)

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)

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.

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

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.

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.

Monitoring and targeting system  

Energy Technology Data Exchange (ETDEWEB)

Management control systems are now the 'norm' for most UK companies. The opportunities to increase company profits by reducing energy costs are often significant and very achievable. To help convince people that energy cost reduction programmes are worthwhile, and often very profitable, the UK Government, via the Energy Efficiency Office, have initiated a series of schemes financially to assist industry to understand and control energy costs. One scheme was to promote the use of energy management techniques using a system known as Monitoring and Targeting. Various industry sectors were selected by the Government and, within each selected sector, the Government funded the introduction of Monitoring and Targeting (M and T) into volunteer companies, the results of which were then to be disseminated to the remainder of the sector.

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

Eavesdropping on GSM: state-of-affairs  

CERN Multimedia

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...

UPS Project for GSM base stations with a fuel cell (PEM fuel cell back-up system) - Final report; Projekt USV fuer GSM-Basisstationen mit BZ (PEM fuel cell back-up system) - Abschlussbericht  

Energy Technology Data Exchange (ETDEWEB)

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

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.)

Groundwater monitoring system  

Energy Technology Data Exchange (ETDEWEB)

A groundwater monitoring system includes a bore, a well casing within and spaced from the bore, and a pump within the casing. A water impermeable seal between the bore and the well casing prevents surface contamination from entering the pump. Above the ground surface is a removable operating means which is connected to the pump piston by a flexible cord. A protective casing extends above ground and has a removable cover. After a groundwater sample has been taken, the cord is disconnected from the operating means. The operating means is removed for taking away, the cord is placed within the protective casing, and the cover closed and locked. The system is thus protected from contamination, as well as from damage by accident or vandalism.

Automatic Fire Sensing and Extinguishig Robot Embedded With GSM Modem  

Directory of Open Access Journals (Sweden)

Full Text Available Our goal is to develop an intelligent multi sensor based fire fighting robot in our daily life. We design the fire detection system using four flame sensors in the fire fighting robot, and program the fire detection and fighting procedure using sensor based method. The fire fighting robot is equipped with four thermistors/flame sensors that continuously monitor the temperature. If the temperature increases beyond the predetermined threshold value, buzzer sounds to intimate the occurrence of fire accident and a warning message will be sent to the respective personnel in the industry and to nearby fire station with the GSM module provided to it. Fire Fighting Robot continuously monitors the temperature at four sensors and if fire accident is true, the robot moves to the direction to which the temperature is recorded to be the relatively maximum among the four sensors and extinguishes the fire with water pump provided to it. After extinguishing the fire it comes back to its initial position. It is more advantageous than a smoke detector as it can extinguish the fire at the inception than waiting for an object to burn and produce smoke. When a smoke detector detects fire it, sprays water all over the place, instead of that particular point of source. It voluntarily detects and extinguishes fire without human aid.

Design and Development of Anti-detaining Student Monitoring System  

Directory of Open Access Journals (Sweden)

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

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)

[en] 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 for

SMS service from your GSM mobile phone  

CERN Multimedia

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...

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 .

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.

Internet Access from CERN GSM subscriptions  

CERN Multimedia

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.

Solar Power Systems Web Monitoring  

CERN Multimedia

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

A grid job monitoring system  

Energy Technology Data Exchange (ETDEWEB)

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.

An Electrical Energy Consumer Load Monitoring and Control System Through SMS Based  

Directory of Open Access Journals (Sweden)

Full Text Available This study presents an SMS based Consumer Load Monitoring and Control System (CLMCS) incorporating the widely used GSM network to facilitate the communication of electrical energy consumption by the user to his mobile phone. Its operation is centered on an AT89C52 microcontroller programmed in assembly language. A dedicated GSM modem with a SIM card is interfaced to the ports of the microcontroller through a PNP transistor (BC557) and a Normally Closed (NC) relay to send SMS notification alert to user’s mobile phone when power supply is restored to his premises and whenever the energy consumed exceeds the maximum value set by the end user in this case 1 kW. This enables the consumer to respond promptly by cutting off power supply to his load unit when not needed. With this, a great deal of energy is saved and the consumer enjoys maximum satisfaction of the electrical energy paid for; hence an improvement, stability and utilization of electrical energy are achievable.

Perception and Reaction of Subscribers to Service S' Cost of GSM Roviders in Nigeria Telecomminication Sector  

Directory of Open Access Journals (Sweden)

Full Text Available In Nigeria today, subscribers own more than one network line in order to have access to various network they intent to call at all time, not this alone the tariff / service cost charge by GSM providers are quite higher compare to each order. Base on this, the study investigates the perception and reaction of subscribers to services' cost of GSM providers in Nigeria telecommunication sector. 150 copies of questionnaire were administered with close monitoring, 100% rate of return were eventually achieved. Purposive and random samplings were used to select the representative members of GSM provider in the state. Simple regression method and Kruskal-Wallis Test were used for the analysis, the results revealed that all null hypotheses are rejected and alternative hypotheses are accepted, that is, there ischain relationship between customer service cost/tariff charges by GSM providers and customer's retention, value of services, new customer generation and that network reliability and accessibility will improve subscribers' reaction positively if at all the service cost is relatively high. From the findings, it was recommended that managers should endeavor to enhance the market share of their organisation through effective customers' service packages. Also, market survey should be carried out on regular basis to determine and re-determine the perception and reaction of subscribers toward GSM provider in Nigeria.

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.

Establishment of Antakya Basin Strong Ground Motion Monitoring System  

Science.gov (United States)

Turkey is located in one of the most active earthquake zones of the world. The cities located along the North Anatolian Fault (NAF) and the East Anatolian Fault (EAF) are exposed to significant earthquake hazard. The Hatay province near the southern terminus of the EAF has always experienced a significant seismic activity, since it is on the intersection of the northernmost segment of Dead Sea Fault Zone coming from the south, with the Cyprean Arc approaching from south-west. Historical records extending over the last 2000 years indicate that Antakya, founded in the 3rd century B.C., is effected by intensity IX-X earthquakes every 150 years. In the region, the last destructive earthquake occurred in 1872. Destructive earthquakes should be expected in the region in the near future similar to the ones that occurred in the past. The strong response of sedimentary basins to seismic waves was largely responsible for the damage produced by the devastating earthquakes of 1985 Michoacan Earthquake which severely damaged parts of Mexico City, and the 1988 Spitak Earthquake which destroyed most of Leninakan, Armenia. Much of this devastating response was explained by the conversion of seismic body waves to surface waves at the sediment/rock contacts of sedimentary basins. "Antakya Basin Strong Ground Motion Monitoring System" is set up with the aim of monitoring the earthquake response of the Antakya Basin, contributing to our understanding of basin response, contributing to earthquake risk assessment of Antakya, monitoring of regional earthquakes and determining the effects of local and regional earthquakes on the urban environment of Antakya. The soil properties beneath the strong motion stations (S-Wave velocity structure and dominant soil frequency) are determined by array measurements that involve broad-band seismometers. The strong motion monitoring system consists of six instruments installed in small buildings. The stations form a straight line along the short axis of Antakya basin passing through the city center. They are equipped with acceleration sensors, GPS and communication units and operate in continuous recording mode. For on-line data transmission the EDGE mode of available GSM systems are employed. In the array measurements for the determination of soil properties beneath the stations two 4-seismometer sets have been utilized. The system is the first monitoring installment in Turkey dedicated to understanding basin effects. The records obtained will allow for the visualization of the propagation of long-period ground motion in the basin and show the refraction of surface waves at the basin edge. The records will also serve to enhance our capacity to realistically synthesize the strong ground motion in basin-type environments.

GTA Beamloss-Monitor System  

International Nuclear Information System (INIS)

[en] 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

Performance Analysis of GSM Coverage considering Spectral Efficiency, Interference and Cell Sectoring  

Directory of Open Access Journals (Sweden)

Full Text Available In this work, the capacity and coverage area of GSM system have been studied. This paper presents the importance of using link budget calculations, determining the path loss and cell range for RF coverage planning and improving capacity using cell-sectoring. The major contribution is to estimate the coverage of GSM system which depends on BS antenna height, transmitting antenna gain, output power of BS for propagation environment such as rural, sub-urban and urban case. MATLAB has been used for simulation and performance evaluation of capacity and coverage in GSM system. Path loss for uplink and downlink has been calculated using Link Calculator software considering 3-sector antenna. Analysis reveals that coverage area improves significantly considering spectral efficiency, interference and cell sectoring. As an example, Google Earth and Radio Works software have been used to estimate the coverage area for a particular area. A 3D coverage map has been formulated using this result.

This project "Software Oriented Data Monitoring System" deals with real time monitoring of patients' parameters like body temperature, heart rate etc. The parameters are checked at regular intervals and Short Messaging Service (SMS) is sent to concerned doctor regarding the measured values. If the obtained parameters are above or below critical values, an alert SMS is also sent to the concerned doctor. This system is very much useful in hospitals, which saves the valuable time of the doctor who otherwise will have to monitor the patients throughout the day. Here the analog data from the sensors is first converted into digital form and is fed to the parallel port of the computer. This data obtained is converted into useful parameters, which is monitored and checked for safe limits. Appropriate SMS is sent to the doctor depending on whether the request is from an alert or routine signal. This is possible by interfacing a mobile phone (Siemens c35i) to the serial port of the computer. The SMS is sent from the co...

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

Domain Modeling for Monitoring Systems  

UK PubMed Central (United Kingdom)

Applying a knowledge-based approach to monitoring and controlling real-time systems is often infeasible because the execution time of backward-chaining queries is unpredictable. In this paper, we show how a decomposition of reasoning into forward and backward inference can bound the execution time of queries. We present a domain modeling technique with algorithms for classifying knowledge into forward and backward categories.

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.

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

International Nuclear Information System (INIS)

[en] 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

The Design of Granary Environmental Monitoring and Control System Based On ARM9 and ZIGBEE  

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.

DOWNHOLE VIBRATION MONITORING & CONTROL SYSTEM  

Energy Technology Data Exchange (ETDEWEB)

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

Radiation monitoring system for astronauts  

International Nuclear Information System (INIS)

Astronauts in space are constantly under the bombardment of radiation particles from trapped electrons, and trapped proton. In addition, cosmic rays, while penetrating the spacecraft shell, generate secondary radiation of neutrons. As astronauts' stay in space is getting longer, the need for a real-time radiation monitoring device has become critical. Thermoluminescent dosemeter (TLD), used onboard both the MIR and the Space Transportation System (STS), cannot provide real-time dose reading. This paper describes a real-time direct read-out device, currently under development, which can measure skin, eye, and Blood Forming Organ (BFO) doses separately. (author).

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  

Directory of Open Access Journals (Sweden)

Full Text Available 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 that 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. And 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.

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

A checklist for PV system monitoring  

Energy Technology Data Exchange (ETDEWEB)

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

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.

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

Outage Probability for GPRS over GSM Voice Services  

UK PubMed Central (United Kingdom)

this paper the outage probability of non-frequencyhopping and frequency hopping systems withdifferent frequency reuse factor has been calculatedin order to investigate those effects. The number ofunused voice channels allocated to GPRS depends onthe difference between the outage level of the existingGSM network and the maximum acceptable level.For both non-frequency hopping and frequencyhopping systems, GPRS affects the QoS of voiceservices of the network with small reuse factor arehigher than that of the network with large reusefactor. GPRS will reduce the cell service area, but thereduction percentage of the cell service area for thesystem with small reuse factor is higher than that forthe system with large reuse factor

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.

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 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 Sistemas de Localización basados en la medición de la intensidad de la seńal, que logran determinar la ubicación del móvil realizando un proceso de triangulación, e (more) stimando la distancia respecto a varias radiobases (al menos tres) a partir de la medición del nivel de la potencia que el móvil recibe de dichas radiobases. Analizando las posibilidades de obtener los niveles de potencia que recibe el móvil de las BTS circundantes, se concluye que existen dos maneras de implementar dicha plataforma a partir de la información del "Measurement Result Information Element": a) Monitoreando la capa 3 de la interfaz Abis entre la BTS y la BSC, o b) Solicitándolo al módulo SIM de los teléfonos GSM. Se explican con detalle, por cada una de estas posibilidades los esquemas de implementación y las condiciones que deben cumplirse con el fin de obtener el "Measurement Result Information Element". Finalmente se presentan las ventajas y desventajas que posee cada uno de estos métodos y se propone la realización de una prueba piloto en la ciudad de Caracas. Abstract in english Feasibility studies to implement a platform for Value Aggregated Services based on the localization of mobile telephones, in a cellular network GSM, begin with the analysis of the systems that allow such localization. The Location Systems based on Signal Strength Measurements are part of these systems. 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 m (more) easurement 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.

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 were: more extensive laboratory testing, including the evaluation of different feedback algorithms for control of the damper; design and manufacture of a field prototype system; and, testing of the field prototype in a drilling laboratory. Phase II concluded on January 31, 2006, and the Phase II final report was issued. Work on Phase III of the project began during the first quarter, 2006. Efforts the current quarter have continued to focus on the manufacture of the prototype and precommercial parts, field test planning and commercialization. The continued extreme lead times quoted by oilfield machine shops for collar components significantly delayed the deployment of the prototype and precommercial units. All parts have now been received for two units, and all but one for the third. Mechanical assembly of the first two systems is complete and the electronics installation and laboratory testing will be finished in April. We have entered into a Memorandum of Understanding with a major US oilfield equipment supplier, which calls for their assisting with our field tests, in cash and in kind. We are close to signing a definitive agreement which includes the purchase of the three precommercial units. We had also signed a CRADA with the Rocky Mountain Oilfield Test Center (RMOTC), and scheduled a test at their site, The RMOTC drilling schedule continues to slip, and the test cannot begin until the first week of May. Based on these factors, we have requested a no-cost extension to July 31, 2007.

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.

Estimating the Computational Requirements of a Software GSM Base Station  

UK PubMed Central (United Kingdom)

In this paper, we describe the software implementation of a GSMbase station and consider the performance of each of its RadioInterface components. The performance of each software moduleis evaluated using both a % CPU metric and a processorindependentmetric based on SPEC benchmarks. These resultscan be used to dimension systems, e.g., to estimate the numberof GSM channels that can be supported by a given processorconfiguration, and to predict the impact of future processor enhancementson base station capacity.1 IntroductionHistorically, the use of software within radio systems has beenrestricted to low bandwidth out-of-band tasks, such as signaling,operations and management. Implementation of the in-band RadioInterface functionality has leveraged analog front ends, thatpartition the band into individual FDM channels, and digitalcomponents that perform the time division and speech processingfunctions. The design of the digital portion is typically based onsome comprom...

Phase II concluded on January 31, 2006. The month of January was devoted to the final preparations for, and conducting of testing of the DVMCS at TerraTek laboratories in Salt Lake City. This testing was concluded on January 27, 2006. Much of the effort in this period was then devoted to the analysis of the data and the preparation of the Phase II final report. The report was issued after the close of the period. Work on Phase III of the project began during this quarter. It has consisted of making some modifications in the prototype design to make it more suitable for field testing an more practical for commercial use. This work is continuing. The redesign effort, coupled with the current extreme lead times quoted by oilfield machine shops for collar components, will delay the deployment of the field prototypes. The precommercial prototypes are being developed in parallel, so the project should be completed per the current schedule.

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].

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 eter troubles, which has operated successfully without any suspension being attributable to the power failures and telemeter troubles.

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

UK PubMed Central (United Kingdom)

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. Bioelectromagnetics © 2013 Wiley Periodicals, Inc.

The present disclosure is directed to a mud metering tank monitoring system for use with an oil well drilling derrick having a sheave on the crown block and a bottom pulley forming a block and tackle arrangement with a cable supporting a traveling block adapted to be attached at one end to a pipe string for raising and lowering the string in a drill casing by a prime mover the other end of said cable being a dead line and having a weight indicator connected thereto. The tank has a mud pump and a fluid connection between the tank and the drill casing. Pipe string counting means is connected to be driven by the sheave in the crown block and to indicate pipe stands lowered into and removed from the drill casing only when a pipe string is being carried by the traveling block. A pair of vertically spaced apart mud sensors are positioned in the mud metering tank, and a computer panel is connected to receive input signals from the pipe string counters and mud sensors. A display panel having indication means shows barrels of mud needed, barrels used, mud weight in the tank and stands pulled and is connected to receive signals from the computer panel. Recorder means is connected to the display panel to keep a running log of quantities listed on the panel plus date and time of day. This recorder is energized by the stand counter and records the above data each time a stand of drill pipe is removed from the hole, and an alarm circuit is in circuit with the computer panel and display panel to compare the actual volume of mud used with the calculated volume required and to energize the alarm to signal the driller should a discrepancy exceed a predetermined limit.

Intelligent Wireless Emergency Alert System for Patient Monitoring using AT89S52 Microcontroller  

Directory of Open Access Journals (Sweden)

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

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

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

Supervisory monitoring system in nuclear power plants  

International Nuclear Information System (INIS)

[en] 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.

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)

Introducing a modular activity monitoring system.  

Science.gov (United States)

In this paper, the idea of a modular activity monitoring system is introduced. By using different combinations of the system's three modules, different functionality becomes available: 1) a coarse intensity estimation of physical activities 2) different features based on HR-data and 3) the recognition of basic activities and postures. 3D-accelerometers--placed on lower arm, chest and foot--and a heart rate monitor were used as sensors. A dataset with 8 subjects and 14 different activities was recorded to evaluate the performance of the system. The overall performance on the intensity estimation task, relying on the chest-worn accelerometer and the HR-monitor, was 94.37%. The overall performance on the activity recognition task, using all three accelerometer placements and the HR-monitor, was 90.65%. This paper also gives an analysis of the importance of different accelerometer placements and the importance of a HR-monitor for both tasks. PMID:22255614

Comparison of bioactivity between GSM 900 MHz and DCS 1800 MHz mobile telephony radiation.  

UK PubMed Central (United Kingdom)

An increasing number of studies find that pulsed Radio Frequency (RF), electromagnetic radiation of both systems of digital mobile telephony, established and commonly used in Europe during the last years, GSM 900 MHz (Global System for Mobile telecommunications) and DCS 1800 MHz (Digital Cellular System), exert intense biological action on different organisms and cells (Hardell et al., 2006; Hyland, 2000; Kundi, 2004; Panagopoulos et al., 2004, 2007). The two types of cellular telephony radiation use different carrier frequencies and give different frequency spectra, but they usually also differ in intensity, as GSM 900 MHz antennas operate at about double the power output than the corresponding DCS 1800 MHz ones. In our present experiments, we used a model biological system, the reproductive capacity of Drosophila melanogaster, to compare the biological activity between the two systems of cellular mobile telephony radiation. Both types of radiation were found to decrease significantly and non thermally the insect's reproductive capacity, but GSM 900 MHz seems to be even more bioactive than DCS 1800 MHz. The difference seems to be dependent mostly on field intensity and less on carrier frequency.

Monitoring the usage of a computer system  

Energy Technology Data Exchange (ETDEWEB)

Controlling the usage of computer systems particularly those operated for the federal government, is an important topic today. Audit requirements have grown to the point where they can be a significant burden to the proprietors of the system. The paper briefly mentions several proposals for responding to increased audit requirements and for monitoring a system to detect unauthorized activity. A technique is proposed for situations where the proscribed or the intended activity can be characterized in terms of program or system performance parameters. The design of a usage monitoring system is outlined. The design is based on enhancing the audit data provided by the monitored system, capturing the audit data in a separate system to protect it from user access, and implementing one of the audit trail analysis systems currently under development.

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 performance of various cellular planning methodsfor GSM, which decrease co-channel interference withoutsacrificing traffic capacity, is evaluated. For measuring theadvantages of each method, the Carrier-to-InterferenceRatio, is calculated. The use of different clusters and thebenefits of sectorisation in C/I are studied. An evaluationof the influence of Frequency Hopping on C/I is also done.The Multiple Re-use Patterns (MRP) method isinvestigated as well, and a comparison is performed withprevious results. The results show that changing the sizefrom 4 to 3 leads to a decrease in C/I of 2.6 dB. Severalreal antennas are studied for sectorisation, the best resultsbeing obtained for the 90 beamwidth one. The use ofsectorisation, together with MRP, allows an increase innetwork performance, without visible additional costs.I.

The Authenticated Tracking and Monitoring System (ATMS)  

Energy Technology Data Exchange (ETDEWEB)

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.

Directory of Open Access Journals (Sweden)

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.

Synergy among international monitoring system technologies  

Energy Technology Data Exchange (ETDEWEB)

This paper describes the results of an International Monitoring System synergy study using Sandia National Laboratory`s IVSEM (Integrated Verification System Evaluation Model). The study compares individual subsystem performance (seismic, infrasound, radionuclide, and hydroacoustic) with integrated system performance. The integrated system exhibits synergy because different sensor technologies cover different locations; thus, the integrated system covers more locations than can any individual subsystem. Energy and system performance can be further enhanced by allowing mixed technology detection and location.

Monitoring system for relativistic particles and nuclei  

International Nuclear Information System (INIS)

The techniques and applications of a monitoring system of relativistic particles and nuclei accelerated at the Dubna synchrophasotron are described. The proposed technique allows one to measure a beam of charged projectiles over a wide range of intensities without any noticeable dependence on the beam profile. The technique was applied to calibrate the systems for measuring the absolute intensity. It facilitated the determination of the total cross sections of monitoring reactions 27Al(p,X)24Na and 27Al(12C,X)24Na at 3.65 AGeV with a sufficient accuracy for the beam flux monitoring by the well-known foil activation technique.

Dynamic Rating and Underground Monitoring System (DRUMS)  

Energy Technology Data Exchange (ETDEWEB)

Drums is an acronym for Dynamic Rating and Underground Monitoring System, with specific application to high-pressure pipe-type cable systems which are the predominant means of underground electric power transmission in the United States. The primary objective of this EPRI-sponsored feasibility study was to establish the technical feasibility of seven DRUMS functions and two novel DRUMS communication schemes. The seven DRUMS functions which monitor the system's vital and measurable parameters in real time and perform system diagnostics in the event of component deterioration, malfunction or failure are: Real Time Current Monitoring and Rating; Leak Detection and Location; Fault Location; Pothead Monitoring; Oil Monitoring; Pipe Protection; and Splice Monitoring. The two DRUMS communication schemes are internal to the pipe cable system. Mechanical Communication will use pressure pulses to transmit data along the system, while the Electrical Communication scheme will use electrical pulses impressed on the pipe. This feasibility study concludes that all of the DRUMS functions and both communication schemes are technically feasible and recommends pursuing these concepts. 17 refs., 19 figs., 6 tabs.

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

UK PubMed Central (United Kingdom)

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.

A Study on Auto Theft Prevention Using GSM  

Directory of Open Access Journals (Sweden)

Full Text Available This paper deals with the design & development of a theft control system for an automobile, which is being used to prevent / control the theft of a vehicle. The developed system makes use of an embedded system based on GSM technology. An interfacing mobile is also connected to the microcontroller, which is in turn, connected to the engine. Once, the vehicle is being stolen, the information is being used by the vehicle owner for further processing. The information is passed onto the central processing insurance system, where by sitting at a remote place, a particular number is dialed by them to the interfacing mobile that is with the hardware kit which is installed in the vehicle. By reading the signals received by the mobile, one can control the ignition of the engine; say to lock it or to stop the engine immediately. Again it will come to the normal condition only after entering a secured password. The owner of the vehicle & the central processing system will know this secured password. The main concept in this design is introducing the mobile communications into the embedded system.

A new infusion pathway intactness monitoring system.  

Science.gov (United States)

A new infusion pathway monitoring system has been developed for hospital and home use. The system consists of linear integrated circuits and a low-power 8-bit single chip microcomputer which constantly monitors the infusion pathway intactness. An AC (alternating current) voltage is induced on the patient's body by electrostatic coupling from the normal 100 volt, 60 Hz AC power line wiring field in the patient's room. The induced AC voltage can be recorded by a main electrode wrapped around the infusion polyvinyl chloride tube. A reference electrode is wrapped on the electrode to monitor the AC voltage around the main electrode. If the injection needle or infusion tube becomes detached, then the system detects changes in the induced AC voltages and alerts the nursing station, via the nurse call system or PHS (personal handy phone system).

INTRODUCTION The Acoustic Flow Monitor (AFM) is a portable system that was designed by the U.S. Geological Survey Cascades Volcano Observatory to detect and monitor debris flows associated with volcanoes. It has been successfully used internationally as part of real-time warning systems in valleys threatened by such flows (Brantley, 1990; Marcial and others, 1996; Lavigne and others, 2000). The AFM system has also been proven to be an effective tool for monitoring some non-volcanic debris flows. This manual is intended to serve as a basic guide for the installation, testing, and maintenance of AFM systems. An overview of how the system works, as well as instructions for installation and guidelines for testing, is included. Interpretation of data is not covered in this manual; rather, the user should refer to the references provided for published examples of AFM data.

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.

Diabetes Monitoring System Using Mobile Computing Technologies  

Directory of Open Access Journals (Sweden)

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

Electronics of LHCb calorimeter monitoring system  

CERN Multimedia

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

Tritium monitor and collection system  

Energy Technology Data Exchange (ETDEWEB)

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.

The AGS Booster Beam Position Monitor system  

International Nuclear Information System (INIS)

To accelerate both protons and heavy ions, the AGS Booster requires a broadband (multi-octave) beam position monitoring system with a dynamic range spanning several orders of magnitude (2 x 1010 to 1.5 x 1013 particles per pulse). System requirements include the ability to acquire single turn trajectory and average orbit information with ± 0.1 mm resolution. The design goal of ± 0.5 mm corrected accuracy requires that the detectors have repeatable linear performance after periodic bakeout at 300 degree C. The system design and capabilities of the Booster Beam Position Monitor will be described, and initial results presented. 7 refs., 5 figs

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.

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.

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

Corrosion and monitoring in refinery systems  

Energy Technology Data Exchange (ETDEWEB)

The major cause of failure in refinery systems is corrosion. From the standpoint of economic loss to the refiner, corrosion related problems are the most expensive and hazardous problems in the industry today. Two basic types of corrosion activity are present in most refineries. These are high temperature corrosion and aqueous phase corrosion. This work focuses on monitoring corrosion mechanisms in the aqueous phase. Thus, the objective is to present a view of such corrosion mechanisms as may exist in a refinery crude unit overhead system, as being typical of refinery aqueous phase corrosion and to describe how these mechanisms can be mitigated and monitored to provide a proactive approach to corrosion control.

An Analysis of GSM Handover based On Real Data  

Directory of Open Access Journals (Sweden)

Full Text Available Handover decisions in GSM networks are based on the difference in received signal strength, between the serving cell and the neighboring cells. But in a practical scenario, particularly in city area ,considering difference in signal level strength alone , is an inferior criteria to decide handover issue ,because the towers are in close proximity & the absolute signal strength is quite good to continue the communication ,without much difficulty .Also, in these environments, multipath reflections, scattering due to moving vehicles & diffraction from multiple building edges ,contributes to poor signal quality, hence forcing the mobile to transmit more power to continue the communication. Continuation of an active call is one of the most important quality measures in the cellular systems. Handover process enables a cellular system to provide such a facility by transferring an active call from one cell to another. Different approaches have been proposed and applied in order to achieve better handover service, by various researchers. The principal parameters considered in the present work, which are used to evaluate handover techniques are: Received signal quality (RxQual), FER, Received signal level, MS-BS distance, transmit power (TxPower) & aggregate C/I. In the present work, thorough analysis has been done for the received signal strength difference threshold, along with other RF quality parameters. To ensure best performance to all mobile users at all times and all locations an active set of parameters has been calculated for critical values along with signal strength difference threshold.

Uranium concentration monitor manual: 2300 system  

Energy Technology Data Exchange (ETDEWEB)

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.

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

Science.gov (United States)

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

A Suppliers Monitoring System Utilizing Control Chart  

Directory of Open Access Journals (Sweden)

Full Text Available Because of the networking technologies progress made, and the collaboration theories developed, the relationship of suppliers and buyers is changed to a collaborative one nowadays. The performance of each member in a supply chain will affect the market competitiveness of the chain. Therefore, how to choose an appropriate collaborative partner becomes an important issue for the initiator of the supply chain. The performance quality of the supplier is the key factor of wining the competition in a market. If the performance quality of the supplier is good and stable, it can supply its downstream with sufficient quality resources and thus build competitive advantages. There are enterprises using information technology to assist the monitoring of the supply chain, from material flow to customer’s relationship. Information technologies, such as Enterprise Resource Planning (ERP), are employed to deal with the problem. Business transaction data, such as delivered quality, price, date, quantity, etc., can be saved in a database and then analyzed to form production policies. The aims of the research are to construct a framework of supplier monitoring information system and to propose a control-chart-based mechanism for monitoring the performance of suppliers in a business-to-business (B2B) supply chain environment. The research uses the delivered quality, date, and quantity as the monitoring indexes, and adopts the concept of control chart to construct an information system that monitors business performances of suppliers in a real time manner.

A Prototype Wire Position Monitoring System  

Energy Technology Data Exchange (ETDEWEB)

The Wire Position Monitoring System (WPM) will track changes in the transverse position of LCLS Beam Position Monitors (BPMs) to 1{micro}m over several weeks. This position information will be used between applications of beam based alignment to correct for changes in component alignment. The WPM system has several requirements. The sensor range must be large enough so that precision sensor positioning is not required. The resolution needs to be small enough so that the signal can be used to monitor motion to 1{micro}m. The system must be stable enough so that system drift does not mimic motion of the component being monitored. The WPM sensor assembly consists of two parts, the magnetic sensor and an integrated lock-in amplifier. The magnetic sensor picks up a signal from the alternating current in a stretched wire. The voltage v induced in the sensor is proportional to the wire displacement from the center of the sensor. The integrated lock-in amplifier provides a DC output whose magnitude is proportional to the AC signal from the magnetic sensor. The DC output is either read on a digital voltmeter or digitized locally and communicated over a computer interface.

Monitoring System for Uninterruptible Power Supply  

Directory of Open Access Journals (Sweden)

Full Text Available In industrial process today, reliability of equipment is very important. Power supply must be able to cater the need of industrial process. In case of power failure, backup power supply system must be able to support the main process plant. This is to ensure smooth operation and product quality. In order to do this, uninterruptible power supply (UPS) system can be used to ensure the reliability, stability and consistency of the entire system. This UPS system must be monitored in order to enable them to react accordingly in response to a fault or power failure. In this project, monitoring system for UPS was designed by using visual basic (VB) to provide a safe and constant 12V DC supply in the case of power disruption. The main power supply, 240V AC was converted to 12V DC as output voltage and a battery will be used as part of the backup system. This system will be able to control the source of power which offers power from LIVE line or power from BATTERY line. The main output voltage was 12V DC and the battery level will be monitored using GUI software created using VB.

Unsupervised user similarity mining in GSM sensor networks.  

UK PubMed Central (United Kingdom)

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

Ubiquitous Health Monitoring Systems: Addressing Security Concerns  

Directory of Open Access Journals (Sweden)

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

Infrared system for monitoring movement of objects  

Energy Technology Data Exchange (ETDEWEB)

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

Corrosion Rate Monitoring in District Heating Systems  

DEFF Research Database (Denmark)

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

Simulating underground mine environmental monitoring systems  

Energy Technology Data Exchange (ETDEWEB)

Mine emergency exercises are required by legislation in Queensland to test the readiness of a mine's emergency response system. The effectiveness of such exercises relies heavily on the realism that can be generated both underground and on the surface. One area where realism is very important is in the control room. An authentic environmental monitoring system that duplicates the actual system used by the mine enables monitoring data to be collected and used throughout the exercise. Enabling alarms to sound as they would in a real scenario greatly adds to the atmosphere and tension in the control room and also provides information to those on the surface in the form that they would receive it in a real situation, allowing them the opportunity to determine what is happening underground. 3 figs.

Science.gov (United States)

A new infusion catheter pathway monitoring system employing linear integrated circuits and a low-power 8-bit single chip microcomputer has been developed for hospital and home use. The sensor consists of coaxial three-layer conductive tapes wrapped around the polyvinyl chloride infusion tube. The inner tape is the main electrode, which records an AC (alternating current) voltage induced on the patient's body by electrostatic coupling from the normal 100 volt, 60 Hz AC power line wiring field in the patient's room. The outside tape layer is a reference electrode to monitor the AC voltage around the main electrode. The center tape layer is connected to system ground and functions as a shield. The microcomputer calculates the ratio of the induced AC voltages recorded by the main and reference electrodes and if the ratio indicates a detached infusion, alerts the nursing station, via the nurse call system or low transmitting power mobile phone.

Environmental monitoring with a portable TLD system  

International Nuclear Information System (INIS)

Two types of TLD systems are used for environmental dose monitoring. One is based on an NHZ-203 laboratory TLD reader and CaSO4:Dy powder. The other is based on CaSO4:Tm bulbs and a small, portable TLD reader built into a cross-country car and operated by means of the car battery. The laboratory TLD system has been used for many years for environmental monitoring and it has been tested and proved satisfactory at international intercomparisons for environmental dosemeters. The new portable TLD system has the advantage of being able to establish the dose in a few minutes at the environmental station. The transport dose is omitted as the TLDs are evaluated at the field site. The evaluation of a bulb needs only a few minutes and the measured dose value can be reported back by radio - an important aspect during an emergency situation. (author).

A design methodology for unattended monitoring systems  

International Nuclear Information System (INIS)

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