    Full Text Available Abstract Electricity is now more than a necessity and its need is increasing day by day resulting in power theft and power scarcity. The purpose of this project is to provide automatic control and monitoring of the Domestic Energy Meter enabling the Electricity Department to read meter readings without anyone visiting each house and also prevent electricity theft .This can be achieved by the use of a Microcontroller Unit that continuously monitors and records the Energy Meter readings in its permanent memory location. This system also makes use of a GSM module for remote monitoring and control of Energy Meter with the help of an interfacing circuitry. The Microcontroller based system continuously records the readings and the live meter reading can be sent to the Electricity department after a count period or on request. This system also can be used to disconnect the power supply to the house in case of non-payment of electricity bills. The Substation will be the receiving end. The data received is fed to a microcontroller at the Substation which will automatically calculate the bill based on tariff provider and display it.

  7. Requirements for gamma radiation survey meter calibration

    International Nuclear Information System (INIS)

    This guide describes the minimum requirements for calibrating a portable analog gamma radiation survey meter by means of a beam calibrator, with a known calibration source. If an alternative method of calibration is to be used the licensee should make a written request to the Atomic Energy Control Board that describes the calibration method to be used, and request the Board's permission to use that method in place of the requirements contained in this guide. This guide explains: the responsibility for survey meter calibration if licensees calibrate their own survey meters, use the services of a Canadian calibration agency, and use the services of a non-Canadian calibration agency; the requirements for survey meter calibration and the supporting documentation; the requirements for record-keeping; and, a calibration certificate, a calibration sticker, and a notification of failure to calibrate form, with examples

  8. Critical Review of Directional Neutron Survey Meters

    International Nuclear Information System (INIS)

    Having been overlooked for many years, research is now starting to take into account the directional distribution of the neutron work place field. The impact of not taking this into account has led to overly conservative estimates of dose in neutron workplace fields. This paper provides a critical review of this existing research into directional survey meters which could improve these estimates of dose. Instruments which could be adapted for use as directional neutron survey meters are also considered within this review. Using Monte-Carlo techniques, two of the most promising existing designs are evaluated; a boron-doped liquid scintillator and a multi-detector directional spectrometer. As an outcome of these simulations, possible adaptations to these instruments are suggested with a view to improving the portability of the instrument. (authors)

  10. Radiation survey meters used for environmental monitoring

    International Nuclear Information System (INIS)

    The Nordic dosimetry group set up the GammaRate project to investigate how its expertise could be used to assure appropriate usage of survey meters in environmental monitoring. Considerable expertise in calibrating radiation instruments exists in the Nordic radiation protection authorities. The Swedish, Finnish, Danish and Norwegian authorities operate Secondary Standard Dosimetry Laboratories (SSDLs) that provide users with calibration traceable to internationally recognised primary standards. These authorities together with the Icelandic authorities have formally cooperated since 2002 in the field of radiation dosimetry. Dosimetry is the base for assesment of risk from ionising radiation and calibration of instruments is an imported part in dosimetry. The Nordic dosimetry group has been focused on cancer therapy. This work extends the cooperation to the dosimetry of radiation protection and environmental monitoring. This report contains the formal, theoretical and practical background for survey meter measurements. Nordic standards dosimetry laboratories have the capability to provide traceable calibration of instruments in various types of radiation. To verify and explore this further in radiation protection applications a set of survey instruments were sent between the five Nordic countries and each of the authority asked to provide a calibration coefficient for all instruments. The measurement results were within the stated uncertainties, except for some results from NRPA for the ionchamber based instrument. The comparison was shown to be a valuable tool to harmonize the calibration of radiation protection instruments in the Nordic countries. Dosimetry plays an important role in the emergency situations, and it is clear that better traceability and harmonised common guidelines will improve the emergency preparedness and health. (Author)

  12. Survey meter using novel inorganic scintillators

    International Nuclear Information System (INIS)

    Single crystal scintillator materials are widely used for detection of high-energy photons and particles. There is continuous demand for new scintillator materials with higher performance because of increasing number of medical, industrial, security and other applications. This article presents the recent development of three novel inorganic scintillators; Pr-doped Lu3Al5O12 (Pr:LuAG), Ce doped Gd3 (Al, Ga)5O12 (Ce:GAGG) and Ce or Eu-doped 6LiCaAlF6 (Ce:LiCAF, Eu:LiCAF). Pr:LuAG shows very interesting scintillation properties including very fast decay time, high light yield and excellent energy resolution. Taking the advantage of these properties, positron emission mammography (PEM) equipped with Pr:LuAG were developed. Ce:GAGG shows very high light yield, which is much higher than that of Ce:LYSO. Survey meter using Ce:GAGG is developed using this scintillator. Ce:LiCAF and Eu:LiCAF were developed for neutron detection. The advantage and disadvantage are discussed comparing with halide scintillators. Eu-doped LiCAF indicated five times higher light yield than that of existing Li-glass. It is expected to be used as the alternative of 3He. (author)

    The large region surrounding the damaged Fukushima Daiichi Nuclear Power Plant has necessitated the use of numerous radiation survey meters with large, robust substrates. The survey meters require efficient scintillation materials that do not require doping and have dimensional stability, such as poly (ether sulfone) (PES) resins. Here, we demonstrate the performance of a model survey meter that uses large PES plates with polished, mirrored surfaces and rough, scattering surfaces. Light collection efficiencies from plates having one or more of these surfaces were quantitatively Characterised with {sup 36}Cl-, {sup 60}Co-, {sup 137}Cs-radioactive sources. The count rates of plates having a combination of mirrored/scattering-surfaces are >1.6 times that for plates having two mirrored surfaces. In addition, a significant amount of radiation-induced light generated in the PES is trapped inside the plate because of its relatively high refractive index. The results indicate that large, undoped PES plates can be used in radiation survey meters. - highlights: • Undoped poly (ether sulfone) (PES) can be used as a scintillation material in radiation survey meters. • Large PES plates with treated surfaces were characterized. • Surface roughening of the plates increased light collection efficiency. • Plates with a combination of mirrored/scattering surfaces work best. • A significant amount of light generated by radiation remains in the PES plates.

  16. Evaluation of uncertainties in the calibration of radiation survey meter

    International Nuclear Information System (INIS)

    In order to meet the requirements of ISO 17025, the quantification of the expanded uncertainties of experimental data in the calibration of survey meters must be carried out using well defined concepts, like those expressed in the 'ISO-Guide to the Expression of Uncertainty in Measurement'. The calibration procedure of gamma ray survey meters involves two values that have to get their uncertainties clearly known: measurements of the instrument under calibration and the conventional true values of a quantity. Considering the continuous improvement of the calibration methods and set-ups, it is necessary to evaluate periodically the involved uncertainties in the procedures. In this work it is shown how the measurement uncertainties of an individual calibration can be estimated and how it can be generalized to be valid for others radiation survey meters. (authors)

  18. Development of PIC-based digital survey meter

    International Nuclear Information System (INIS)

    The need of radiation monitoring and monitoring of radioactive contamination in the workplace is very important especially when x-ray machines, linear accelerators, electron beam machines and radioactive sources are present. The appropriate use of radiation detector is significant in order to maintain a radiation and contamination free workplace. This paper reports on the development of a prototype of PIC-based digital survey meter. This prototype of digital survey meter is a hand held instrument for general-purpose radiation monitoring and surface contamination meter. Generally, the device is able to detect some or all of the three major types of ionizing radiation, namely alpha, beta and gamma. It uses a Geiger-Muller tube as a radiation detector, which converts gamma radiation quanta to electric pulses and further processed by the electronic devices. The development involved the design of the controller, counter and high voltage circuit. All these circuit are assembled and enclosed in a plastic casing together with a GM detector and LCD display to form a prototype survey meter. The number of counts of the pulses detected by the survey meter varies due to the random nature of radioactivity. By averaging the reading over a time-period, more accurate and stable reading is achieved. To test the accuracy and the linearity of the design, the prototype was calibrated using standard procedure at the Secondary Standard Dosimetry Laboratory (SSDL) in MINT. (Author)

    Handheld multi-gas meters (MGMs) are equipped with sensors to monitor oxygen (O2) levels and additional sensors to detect the presence of combustible or toxic gases in the environment. This report is limited to operational response-type MGMs that include at least four different sensors. These sensors can vary by type and by the chemical monitored. In real time, the sensors report the concentration of monitored gases in the atmosphere near the MGM. To provide emergency responders with information on handheld multi-gas meters, the System Assessment and Validation for Emergency Responders (SAVER) Program conducted a market survey. This market survey report is based on information gathered between November 2015 and February 2016 from vendors, Internet research, industry publications, an emergency responder focus group, and a government issued Request for Information (RFI) that was posted on the Federal Business Opportunities website.

  1. Study on the Calibration of Environmental Survey Meter

    International Nuclear Information System (INIS)

    Study on calibration of environmental survey meter using 60Co dan 137Cs standard gamma sources made in P3KRBiN had been done. Shadow-shield and free field calibration techniques were used to calibrate a variety of environmental survey meters, which are typically energy compensated GM counter, high-pressure ionization chamber and Na(I)Tl counter. The exposure rate from the gamma source was calculated based on its activities given by the manufacture. The shadow shield calibration technique was carried out in the calibration room with the size of 12 m x 6.6 m x 2.94 m with and without shadow shield at the source to detector distances of 100 cm, 150 cm and 200 cm and the height of the source from the floor was 110 cm. The calibration factor was determined by the ratio between the exposure rate of the gamma source and the reading with and without shadow shield. The free field calibration technique was carried out at free field with the size of 80 m x 70 m with and without the sources present at the source to detector distances of 100 cm, 150 cm and 200 cm and the height of the source from the floor was 100 cm. The calibration factor was determined by the ratio between the nominal exposure rate of the gamma source and the reading with and without the source present. Generally, the calibration results using shadow shield and free field calibration techniques for all survey meters were in the permitted range which was 0.8 ≤ CF ≤ 1.2 for 137Cs gamma source. So shadow shield calibration technique can be used for calibration the environmental survey meter. (author)

  2. Review of Scattering Corrections for Calibration of Neutron Survey Meters

    International Nuclear Information System (INIS)

    In this study, the calibration factors of the several neutron survey meters obtained by both the shadow-cone method and semi-empirical method. Generally and theoretically, the calibration factors obtained by the methods given in ISO 8529-2 have the similar values. However we found that the calibration factors obtained by two methods have the different values. The calibration factors were obtained by two calibration method and the validity of the 'shadow-cone method' was proven by the MCNPX calculation. The total scattering correction of the conventional true scatter effects in the 'shadow-cone method' was under-estimated by 4.0.8.1% rather than the scatter correction in the 'semi-empirical method'. This lower calibration factor than that of the 'semi-empirical method' is owing to the under-response of the neutron survey meters in the thermal neutron field. These results are elucidated from that most of single-moderator-based survey meters excluding tissue-equivalent proportional counter (TEPC) have an under-response in the thermal neutron field. It is concluded that a great care is needed while calibrating a survey meter using a shadow-cone calibration method and in interpreting the readouts. ISO 8529-2 (the International Organization for Standardization) recommends four different approaches to the problem of correcting for scatter effects. The first three methods, denoted as the shadow-cone method, the generalized fit method, and the semi-empirical method, usually involve an initial set of careful measurements as a function of the distance between neutron source and detector

    International Nuclear Information System (INIS)

    In response to the major changes now taking place in its business environment, Tokyo Gas will restructure its meter-reading operations, including services peripheral thereto, to build a strong corporate structure toward the year 2010. Specifically, Tokyo Gas will proceed to intentional automatic meter reading, making use of the know-how it has accumulated doing so as part of a value-added service it has been marketing since 1988. Tokyo Gas will also use its two-way communication infrastructure to promote improved operational efficiency and labor savings. Intentional automatic meter reading will enable Tokyo Gas, over the 13 years following its commencement, to realize total cost savings of 53.5 billion yen and reassign 776 employers to strategic work. Tokyo Gas will also utilize its two-way communication infrastructure to provide additional services, including value-added services that will generate upwards of 3.7 billion yen margin annually and contracted meter reading services for utilities throughout Japan. Tokyo Gas will thus carry out a business expansion that will enable it to grow limitlessly together with society. (au)

  4. Semi-automatic drawings surveying system

    International Nuclear Information System (INIS)

    A system for the semi-automatic survey of drawings is presented. Its design has been oriented to the reduction of the stored information required for the drawing reproduction. This equipment consists mainly of a plotter driven by a micro-computer, but the pen of the plotter is replaced by a circular photodiode array. Line drawings are first viewed as a concatenation of vectors, with constant angle between the two vectors, and then divided in arcs of circles and line segments. A dynamic analysis of line intersections with the circular sensor permits to identify starting points and end points in a line, for the purpose of automatically following connected lines in drawing. The advantage of the method described is that precision practically depends only on the plotter performance, the sensor resolution being only considered for the thickness of strokes and the distance between two strokes.

  5. Digital Survey Meter based on PIC16F628 Microcontroller

    International Nuclear Information System (INIS)

    A Digital Survey Meter based on PIC16F628 Microcontroller was designed using simple Geiger-Muller Counter ZP1320 made by Centronic in the UK as detector. The sensitivity of this tube is about 9 counts/s at 10μGy/h. It is sensitive to gamma and beta particles over 0.25 MeV. It has a sensitive length of 28mm. Count rate versus dose rate is quite linear up to about 104 counts/s. Indication is given by a speaker which emits one click for each count. In addition to the acoustic alarm, the meter works according one of three different measurement modes selected using appropriate 3 states switch: 1- Measurement of Dose rate ( in μGy/h) and counting rate ( in CPS) , for High counting rates. 2- Measurement of Dose rate ( in μGy/h) and counting rate ( in CPM), for Low counting rates. 3- Accumulated Counting with continues display for No. of Counts and Counting Time with a period of 2 Sec. The results are Displayed on an Alphanumerical LCD Display, and the circuit will give many hours of operation from a single 9V PP3 battery. The design of the circuit combines between accuracy, simplicity and low power consumption. We built 2 Models of this design, the first only with an internal detector, and the second is equipped with an External Detector. (author)

  6. Automatic Meter Reading using Power Line Signaling and Voltage Zero-crossing Detection

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available In India, the electric power transmission and distribution loss is very high, about 7% in transmission and 26% in distribution. Though deployment of automated meter reading system will reduce losses, particularly in distribution, penetration of automated meter reading is low due to high costs involved. World over, the Two-Way Automatic Communications System (TWACS is the most widely used power line communications technology offering two-way communication between substation and end users. The TWACS introduces disturbance on the power system voltage for short durations near zero-crossing to generate the outbound (from substation to end user signal. To generate the inbound (from end user to substation signal, short duration current pulses are introduced, near voltage zero-crossings. Information is generated as a sequential combination of voltage disturbances for the outbound signal and current pulses for the inbound signal. The current study proposes a low-cost modification of the TWACS to reduce voltage and current harmonics. The proposed system has been modelled and simulated using SIMULINK/SIMPOWER Systems. The simulation results show that there is a reduction in voltage harmonics from 0.84 to 0.17% and in current harmonics from 2.07 to 1.10%.

  7. Performance of radiation survey meters in X- and gamma-radiation fields

    International Nuclear Information System (INIS)

    The aim of this work was to investigate the different types of radiation detectors commonly used for radiation protection purposes as survey meters. The study was performed on survey meters that use different detectors as ionisation chamber, Geiger Mueller (GM) counter and scintillation detector. For each survey meter, energy dependence and angular response in X- and gamma-radiation fields was tested. The following commercially available survey meters were investigated: ionisation chambers Victoreen 451P, Babyline 31 and VA-J-15A, Geiger counter MRK-M87, 6150 AD6 and FAG FH 40F2 and scintillation counter 6150 ADB. As a source of gamma radiation, 137Cs and 60Co were used whereas X-ray radiation fields were generated using an X-ray unit. The radiation characteristics of the survey meters were mostly in compliance with references estimated by standard IEC 1017-2. However, some of them showed larger deviation at lower energies. GM counters exhibit strong energy dependence for low-energy photons. (authors)

    Increasing concern about decline in biodiversity has created a demand for population surveys. Acoustic monitoring is an efficient non-invasive method, which may be deployed for surveys of animals as diverse as insects, birds, and bats. Long-term unmanned automatic monitoring may provide unique...... data sampling rates (500kHz). Using a sound energy threshold criterion for triggering recording, we collected 236GB (Gi=10243) of data at full bandwidth. We implemented a simple automatic method using a Support Vector Machine (SVM) classifier based on a combination of temporal and spectral analyses...... to classify events into bat calls and non-bat events. After experimentation we selected duration, energy, bandwidth, and entropy as classification features to identify short high energy structured sounds in the right frequency range. The spectral entropy makes use of the orderly arrangement of frequencies...

    We propose a low-cost robotic optical survey aimed at $1-300$ m Near Earth Objects (NEO) based on four state-of-the-art telescopes having extremely wide field of view. The small Near-Earth Asteroids (NEA) represent a potential risk but also easily accessible space resources for future robotic or human space in-situ exploration, or commercial activities. The survey system will be optimized for the detection of fast moving - trailed - asteroids, space debris and will provide real-time alert notifications. The expected cost of the system including 1-year development and 2-year operation is 1,000,000 EUR. The successful demonstration of the system will promote cost-efficient ADAM-WFS (Automatic Detection of Asteroids and Meteoroids - A Wide Field Survey) systems to be built around the world.

  13. Automatic device for measuring β-emitting sources: P.A.P.A. β-meters

    International Nuclear Information System (INIS)

    The apparatus described is designed for measuring β-emitting elements by the absorption method; it is suitable for carrying out a large number of routine analyses. A mechanical device pushes an aluminium absorption set automatically between the source and the detector; the movement is programmed for cutting on and off by a transistorized electronic unit, with printing out and punching of the results on tape; then this can be mathematically processed by a computer (tracing of absorption spectra, extrapolation and calculation of the activity). The detector is either a β-probe or a proportional counter with a specially designed loop. For routine measurements, the accuracy obtained, with all corrections made, is from 5 to 8 per cent; the reproducibility is about 2 per cent. (authors)

    2007-04-06

    Microg-LaCoste (MGL) was contracted by Pacfic Northwest National Laboratories (PNNL) to record borehole gravity density data in 3 wells at the HanfordWaste Treatment Plant (WTP) site. The survey was designed to provide highly accurate density information for use in seismic modeling. The borehole gravity meter (BHGM) tool has a very large depth of investigation (hundreds of feet) compared to other density tools so it is not influenced by casing or near welbore effects, such as washouts.

  15. Calibration of survey meters at the Algerian Secondary Standard Dosimetry Laboratory

    International Nuclear Information System (INIS)

    Full text: The Algerian Secondary Standard Dosimetry Laboratory, which became a Regional AFRA Designated Centre for French spoken countries, in the field of calibration since 2005, has developed and implemented methodologies for the calibration of radiation protection instruments such as survey meters. These instruments were initially calibrated in terms of air kerma free in air (NK) in 60Co, 137Cs gamma radiations. Although the recommended calibration quantity is H*(10) (Sv/h), most of instruments measure different physical quantities and problems about the expression of calibration factor in the calibration certificates are always raised. In order to switch to calibrations in terms of H*(10), a feasibility study was performed using instruments submitted for calibration at the SSDL. This paper presents the variation of the calibration coefficients, Fc, obtained since 2005 for three types of survey meters. The uncertainty components involved in the determination of Fc are analysed in details. Material and method: This study included the most used survey meters in Algeria and received at the SSDL in 2005 and 2006 which consist of 127 survey-meters of type Automess (different models), 80 Ludlum model 3 and 23 Graetz X 5 DE. Calibrations were performed using the beam output decay method. This output was determined with the Reference Standard chamber of type NE 2575 in 2005 and LS01 in 2006, both calibrated at the IAEA calibration laboratory. The average calibration coefficients, Fc, which converts the instruments reading to ambient equivalent absorbed dose, are calculated and the relative standard deviations assessed. The variation of calibration coefficients, for each type of instruments, is compared to the overall stated uncertainty for this coefficient. Results and discussion: The mean calibration coefficients in terms of H*(10) were lying from 0.993 ± 2.55% and 1.039 ± 3.16% for the Automess survey meters and from . The results are 1.215 ± 5.93%, 1.149 ± 14

    2013-01-01

    Full Text Available The Automatic Meter Reading (AMR network for the next generation Smart Grid is required to possess many essential functions, such as data reading and writing, intelligent power transmission, and line damage detection. However, the traditional AMR network cannot meet the previous requirement. With the development of the WiFi sensor node in the low power cost, a new kind of wireless sensor network based on the WiFi technology can be used in application. In this paper, we have designed a new architecture of WiFi-based wireless sensor network, which is suitable for the next generation AMR system. We have also proposed a new routing algorithm called Energy Saving-Based Hybrid Wireless Mesh Protocol (E-HWMP on the premise of current algorithm, which can improve the energy saving of the HWMP and be suitable for the WiFi-based wireless sensor network. The simulation results show that the life cycle of network is extended.

  18. Evaluation of the surface contamination density with 51Cr by direct measurement method using a GM survey-meter

    International Nuclear Information System (INIS)

    It is difficult to detect a low level contamination with 51Cr using a scintillation survey-meter because background counting rate of the survey-meter is high and emitted rate of γ-rays (0.320 MeV) from 51Cr is less than 10%. We examined whether a surface contamination with 51Cr can be detected directly with a GM survey-meter. As the result, the detection efficiency and detection limit of the GM survey-meter against the surface contamination were more than 0.6%(4π) and 4.6 Bq/cm2, respectively. From measurement of transmittance of radiations from 51Cr against poly (vinylidene chloride) seat, it became clear that the majority (about 98%) of detected radiations with the GM survey-meter is characteristic X-rays. These results show that the GM survey-meter can be used as a detector to check a surface contamination with 51Cr in controlled area. (author)

  19. Method for monitoring radioactive cesium concentration in water using cesium adsorption disk and GM survey meter

    International Nuclear Information System (INIS)

    A method for monitoring radioactive cesium concentration in water using a cesium adsorption disk and a GM survey meter has been developed to ascertain whether the water quality meets standards on radiological contaminants in water. In this method, both dissolved and suspended forms of radioactive cesium are collected on the cesium adsorption disk by means of filtration of a water sample. Beta count rate of the disk is converted into radioactivity using a conservative calibration factor obtained here. The present method was applied to monitoring of decontaminated water of an outdoor school swimming pool in Date City after Fukushima Daiichi Nuclear Power Plant accident. (author)

  20. Application of groundwater flow meter with single well to groundwater flow survey in fractured rock, (1)

    International Nuclear Information System (INIS)

    In this study, we applied the groundwater flow meter developed by CRIEPI to the groundwater flow survey with single well named AN-1 of Tounou mine that is owned by PNC and located in Mizunami-city, Gifu-prefecture. This study forms a link in the chain of a cooperative research work, that is aimed to establish the technique for evaluation of the characteristics of fractured rocks, between CRIEPI and PNC. The principal results are summarized as follows. 1) We improved the structure of this groundwater flow meter into having newly a intermediate air packer made with rubber, so that the measurements of local flow characteristics (velocity and direction) of groundwater flow could be performed more effectively. 2) The groundwater flow velocity in rocks is generally so low that we can't ignore the effect of diffusion of the tracer (distilled water) in comparison with advection. Then, we introduced a method of analysis, that is based on a advective-diffusion equation and is able to specify the advective component (flow), on the velocity and direction of groundwater flow. From a experimental results, we had good prospects for being able to detect the groundwater flow with velocity that is so low as to be a few cm per year, by using the groundwater flow meter system above mentioned. 3) We applied this type of groundwater flow meter to a field test that has three measurement points within about 150 m depth with AN-1 well in Tounou mine, so that the groundwater velocity of each points were measured to be from a few m to a few cm per year.

  1. Calibration and performance testing of survey meters used in ionizing radiation applications in Greece

    International Nuclear Information System (INIS)

    Radiation protection monitoring is an essential activity in any facility using radioactive sources or isotopes, for medical, industrial, research and other ionizing radiation application. Quantification of the radiation levels in a workplace in order to designate an area as controlled or supervised or to estimate the effectiveness of shielding is frequently needed. According to the Greek legislation the levels of ionizing radiation must be adequately monitored and the equipment used for this purpose should be tested and calibrated at appropriate intervals that should not exceed two years. The Ionizing Radiation Calibration Laboratory (H.I.R.C.L.) of the Greek Atomic Energy Commission (G.A.E.C.) has established a detailed calibration procedure for radiation protection equipment in order to investigate the accuracy of the various detectors and to provide homogeneous response of their use in Greece. H.I.R.C.L. has been accredited according to E.N./ISO 17 025, for radiation protection calibrations by the Hellenic Accreditation Council, E.S.Y.D.. This study summarizes the results of calibrations and performance testing in nearly 650 survey meters of different types. For each instrument, operational characteristics such as, accuracy and linearity in every scale, energy and angular dependence have been studied. The calibration factor in each scale was also determined. The measured values were compared to the suggested limits. The results were classified in seven dose intervals (from 0,1 + Sv/h up to >1 Sv/h). The statistical distribution showed tales that exceeded the + 20% criterion of accuracy in all dose intervals. About 20% of them showed non - linearity in their response. Moreover, about 8,5% of the instruments with more than one operational scales, showed accuracy discrepancies in some scales, while the others where found to operate satisfactory. Almost 9% of the instruments were found to be out of order because of technical and operational malfunctions. About 270

  2. Borehole gravity meter survey in drill hole USW G-4, Yucca Mountain Area, Nye County, Nevada

    International Nuclear Information System (INIS)

    Drill hole USW G-4 was logged with the US Geological Survey borehole gravity meter (BHGM) BH-6 as part of a detailed study of the lithostratigraphic units penetrated by this hole. Because the BHGM measures a larger volume of rock than the conventional gamma-gamma density tool, it provides an independent and more accurate measurement of the in situ average bulk density of thick lithologic units. USW G-4 is an especially important hole because of its proximity to the proposed exploratory shaft at Yucca Mountain. The BHGM data were reduced to interval densities using a free-air gradient (F) of 0.3083 mGal./m (0.09397 mGal/ft) measured at the drill site. The interval densities were further improved by employing an instrument correction factor of 1.00226. This factor was determined from measurements obtained by taking gravity meter BH-6 over the Charleston Peak calibration loop. The interval density data reported herein, should be helpful for planning the construction of the proposed shaft

    In this work, the radiation exposure in nuclear medicine is evaluated by measuring dose rates in the proximity of patients and those in close contact to sources like capsules and syringes. A huge number of different survey meters (SMs) are offered commercially. This topic has recently gained interest since dosemeters and active personal dosemeters (APD) for the new dose quantities (ambient and directional dose equivalent) have become available. One main concern is the practical use of SMs and APD in daily clinical routines. Therefore, the radiation field of four common radiopharmaceuticals containing (18)F, (90)Y, (99m)Tc and (131)I in radioactive sources or after application to the patient was determined. Measurements were carried out with different SMs and for several distances. Dose rates decline significantly with the distance to the patient, and with some restrictions, APD can be used as SMs. PMID:25071244

  4. Survey of environmental radiation dose rates from Tokushima to Misasa hot spring in Tottori using a scintillation survey meter

    International Nuclear Information System (INIS)

    In this work, a survey of environmental radiation dose rates from Tokushima to Misasa Hot Spring in Tottori has been performed using a portable NaI(Tl) scintillation survey meter equipped in a car. It has been possible to record the environmental radiation dose rates together with time information by a portable personal computer. In the course of the present survey, the maximum value of the environmental radiation dose rates was 0.203 μSv/h into Kokubunji tunnel in Kagawa prefecture, while the minimum value was 0.016 μSv/h on the bridge of Seto-Ohashi. Radiation dose rates into tunnels were higher than those of public places, in contrast, those on bridges were lower. This trend is in agreement with generally recognized one. That is, the radiation dose rates into tunnels will increase by a top and sides of bedrocks, while those on bridges will decrease by the effect of shielding of river and sea waters for the natural occurring radiation due to bedrocks. Comparing the environmental radiation dose rates at public places in the following four prefectures, Tokushima, Kagawa, Okayama, and Tottori, except those tunnels and bridges, we found that the average radiation dose rate in Tottori was 0.079 ± 0.011 μSv/h and it was the highest value in the four prefectures. This suggests that granites, which generally have the highest content of U and Th, will be geologically distributed in the Chugoku District than the Shikoku One. (author)

    Braun, Jaroslav; Štroner, Martin; Urban, Rudolf

    2015-05-01

    All surveying instruments and their measurements suffer from some errors. To refine the measurement results, it is necessary to use procedures restricting influence of the instrument errors on the measured values or to implement numerical corrections. In precise engineering surveying industrial applications the accuracy of the distances usually realized on relatively short distance is a key parameter limiting the resulting accuracy of the determined values (coordinates, etc.). To determine the size of systematic and random errors of the measured distances were made test with the idea of the suppression of the random error by the averaging of the repeating measurement, and reducing systematic errors influence of by identifying their absolute size on the absolute baseline realized in geodetic laboratory at the Faculty of Civil Engineering CTU in Prague. The 16 concrete pillars with forced centerings were set up and the absolute distances between the points were determined with a standard deviation of 0.02 millimetre using a Leica Absolute Tracker AT401. For any distance measured by the calibrated instruments (up to the length of the testing baseline, i.e. 38.6 m) can now be determined the size of error correction of the distance meter in two ways: Firstly by the interpolation on the raw data, or secondly using correction function derived by previous FFT transformation usage. The quality of this calibration and correction procedure was tested on three instruments (Trimble S6 HP, Topcon GPT-7501, Trimble M3) experimentally using Leica Absolute Tracker AT401. By the correction procedure was the standard deviation of the measured distances reduced significantly to less than 0.6 mm. In case of Topcon GPT-7501 is the nominal standard deviation 2 mm, achieved (without corrections) 2.8 mm and after corrections 0.55 mm; in case of Trimble M3 is nominal standard deviation 3 mm, achieved (without corrections) 1.1 mm and after corrections 0.58 mm; and finally in case of Trimble

  8. Empowered? Examining self-disconnection in a postal survey of electricity prepayment meter consumers in New Zealand

    International Nuclear Information System (INIS)

    Prepayment metering is an electricity payment method often used by low-income consumers. Fuel poverty is an important public health problem in New Zealand, and is likely to be a particular problem for those using prepayment metering. This paper details a nationwide postal survey of consumers undertaken with the support of three major electricity retailers, which investigated the advantages and disadvantages of using prepayment metering from a consumer perspective. The study surveyed a total pool of 359 randomly selected consumers across the three companies, a response rate of 48%. The study found that while almost all respondents felt the benefits of using prepayment outweighed the risks of running out of credit or ‘self-disconnection’, 53% of respondents experienced self-disconnection in the past year. Of concern, over a third of respondents experiencing self-disconnection were without electricity for more than 12 h. The frequency of self-disconnection was also high, with 17% of those disconnecting reporting six or more events in the past year. Government intervention could reduce the risks and disadvantages involved with using prepayment metering, which could then support initiatives aimed at reducing fuel poverty. - Highlights: ► Results of a national postal survey of New Zealand electricity prepayment users. ► Self-disconnection is an extreme outcome of fuel poverty. ► 53% of respondents experienced self-disconnection in the past year. ► Self-disconnection is problematic, lasting 12 or more hours for 38% of those who disconnected. ► Government policies could minimise health effects and capture benefits of prepayment metering.

  12. Effects of the protective covers against radioactive contamination of a GM survey meter probe on the counting value

    International Nuclear Information System (INIS)

    A GM survey-meter probe is usually covered with a polyethylene or poly (vinylidene chloride) sheet to prevent radioactive contamination. We investigated the effects of the thickness of these protective covers on the counting values of the survey-meter. A source was put on a detection face of the probe wrapped with the protective cover, and the counting values of the radiation from the source (14C, 35S, 45Ca, 51Cr and 32P) were measured. As the result, the decay rate of the counting values of 14C and 35S were high, that of 32P was low, and that of 45Ca was between these nuclides, in any thickness of these protective covers. On the other hand, in the case of 51Cr, the decay rate of the counting values with the poly (vinylidene chloride) cover was far higher than that with the polyethylene in any thickness. From calculation of transmittance of radiation from 51Cr, such difference in the decay rate between these covers was ascribed to the difference in constituent elements of these covers. Further, it was confirmed that the differences in the decay rates of the counting values by using the polyethylene sheets were available to identify certain of nuclides. (author)

  13. Atlantic 3800-meter radioactive waste disposal site survey (1978): sedimentary, micromorphologic and geophysical analyses. Final report

    International Nuclear Information System (INIS)

    During the period of 22-28 July, 1978, five dives were made in the manned submersible ALVIN into the Atlantic Ocean 3800 meter depth radioactive waste disposal site located in the Hudson Canyon channel approximately 320 kilometers from the Maryland-Delaware coast. A geological description of the site was made by direct examination of the bottom topography, bedrock exposures, sedimentary and erosional processes, and sediment cores collected from the dumpsite area. Observations within a depth range of 3985-3830 meters revealed angular blocks and piles of displaced channel wall rock, boulder and cobble olistoliths of Eocene-age chalks derived from higher elevations on the slope, and bedforms such as ripples and scour marks which imply the existence of periodic strong currents. Local benthic fauna were sparse. Three low-level radioactive waste drums were examined from the submersible, and one was subsequently recovered for corrosion, and concrete deterioration analyses. Photographic and visual evidence suggest that downslope transport of objects such as talus blocks, olistoliths, and radioactive waste drums has occurred in this area

  19. Correspondence between the count rates of the various GM tube survey meters and the initial setting value based on OIL4

    International Nuclear Information System (INIS)

    After the Fukushima Daiichi Nuclear Power Station accident, the Nuclear Emergency Response Guidelines developed by the Nuclear Regulatory Authority of Japan has introduced Operational Interventional Levels (OILs). Particularly, OIL4 that is the screening level for decontamination against surface contaminations on the skin, clothes and others wad adopted, and the default OIL4 value is 13,000 cpm. The guideline mentions that conversion of count rate is necessary when using different models of GM tube survey meters. Thus, count rate measurements using a surface radiation source of 10 cm square were performed with four typical GM tube survey meters in this work, and the instrument efficiencies were compared. In addition, the dependences of the distance from the detector window of the GM tube survey meter to the source are also evaluated between 1 cm and 5 cm. The resulting count rates for OIL4 of the tested GM tubes survey meters varied between 7,000 and 9,000 cpm. Count rates were decreasing as distance from the source increased with the different ratios depending on the model of GM tube survey meter. The screening levels showed between 3,000 and 6,000 cpm when distance between the source and the detector windows were 5 cm. This study suggested the importance to evaluate the intrinsic characteristics of the model and to derive and appropriate screening level at a few centimeters from the screening object in order to detect contamination reliably.

    2016-01-01

    Full Text Available This study is focused on the radiological investigation of terrestrial gamma radiation in the test field with soil samples from different minefields in the Federation of Bosnia and Herzegovina. Measurements of ambient dose equivalent rate, commonly referred to as “air dose rate”, in the test field located in the Tuzla Canton, were performed by RADIAGEMTM 2000 portable survey meter, based on energy-compensated Geiger-Muller counter. Its performances were tested in the laboratory conditions with gamma point sources. Since all the samples in the test field were exposed to the same cosmic radiation, there was a possibility to assess a relative contribution of terrestrial gamma radiation due to soil samples of different composition. One set of measurements in the test field was performed with RADIAGEMTM 2000, at a height of about one meter above the ground and basic statistical parameters indicated that there was no significant difference of terrestrial gamma radiation from different soil samples. The other set of measurements was carried out with the same device placed on the ground in the test field. Processing of experimental data on terrestrial gamma radiation has shown that it was possible to make a difference between relative contributions of terrestrial gamma radiation from individual soil samples. The results of investigation could be useful for multiple purposes of public interest.

    The most recent study of the Wide Field Infrared Survey Telescope (WFIRST) mission is based on reuse of an existing 2.4m telescope. This study was commissioned by NASA to examine the potential science return and cost effectiveness of WFIRST by using this significantly larger aperture telescope. We review the science program envisioned by the WFIRST 2012-2013 Science Definition Team (SDT), an overview of the mission concept, and the telescope design and status. Comparisons against the previous 1.3m and reduced cost 1.1m WFIRST design concepts are discussed. A significant departure from past point designs is the option for serviceability and the geostationary orbit location which enables servicing and replacement instrument insertion later during mission life.

    Network monitoring of extensive water distribution systems as you can find in rural areas causes high costs. Therefore a current research project tries to find cost savings by using automatic meter reading of main flow meters within the network. The project focuses on improving leakage control as well as optimizing rehabilitation investments. By operation of a pilot plant significant potentialities for cost savings already could be identified. Additionally the calculation of the optimal time of rehabilitation shows that automatic meter reading is able to reduce investment costs. For the calculation of the costs the research team developed a software that supports the user in this decision making process. (orig.) [German] In grossraeumigen Wasserversorgungsnetzen, wie sie vor allem im laendlichen Raum anzutreffen sind, ist die Netzueberwachung mit erheblichem Aufwand verbunden. In einem laufenden Forschungsvorhaben wird untersucht, inwieweit sich Einsparungen durch Einsatz von fernablesbaren Grosswasserzaehlern realisieren lassen. Im Zentrum steht dabei die Verbesserung der Leckageueberwachung sowie eine Optimierung der Reinvestitionsplanung. Anhand ausgewaehlter Untersuchungsgebiete des beteiligten Wasserversorgers konnten bereits eindeutige Einsparpotenziale im Netz- und Leckagenmanagement durch den Einsatz der Fernablesung nachgewiesen werden. Auch die Berechnung des betriebswirtschaftlich optimalen Reinvestitionszeitpunkts laesst darauf schliessen, dass der Einsatz der Fernablesung zu einer Kostenreduktion fuehrt. Zur Berechnung der Kosten wurde eine Software entwickelt, die den Anwender bei seiner Entscheidungsfindung unterstuetzt. (orig.)

  5. An automatic locating and data logging system for radiological walkover surveys

    International Nuclear Information System (INIS)

    Oak Ridge National Laboratory has developed an Ultrasonic Ranging and Data System (USRADS) to track a radiation surveyor in the field, to log his instrument's reading automatically, and to provide tabular and graphical data display in the field or in the office. Once each second, USRADS computes the position of the radiation surveyor by using the time-of-flight of an ultrasonic chirp, emitted by a transducer carried in a backpack, to stationary receivers deployed in the field. When the ultrasonic transducer is pulsed, a microprocessor in the backpack radios the start time and survey instrument's reading to the master receiver at the base station (a van or truck). A portable computer connected to the master receiver plots the surveyor's position on the display, and stores his position and instrument reading. The CHEMRAD Corporation has just completed a survey of the ORNL main plant area using two radiation survey instruments simultaneously: a ratemeter connected to a NaI crystal that is swung in a arc near the ground, to look for surface contamination; and a small pressurized ionization chamber (PIC), attached to the backpack frame at a height of 3 ft, to measure the exposure rate. 3 refs., 5 figs

  6. A 50 m laser interferometer for automatic calibration of surveying tapes using wireless communication

    International Nuclear Information System (INIS)

    A 50 m linear measuring interferometer, consisting of a precision laser interferometer, a 51 m long guide rail, a moving carriage, an optical microscope with a CCD camera and an image processor, is described here. The system is designed for the automatic calibration of surveying tapes. The carriage can move up to 50 m along the guide rail. The dc servo motor, which is fixed on the carriage, drives the carriage and its speed is controlled by a computer through wireless communication. The CCD camera captures the image of tape lines through the microscope fixed on the stage, and the image is wireless transferred to the image processor installed in the computer. The image processor calculates the deviation between the center of the line and the field-of-view of the CCD camera, and the laser interferometer measures the displacement of the carriage simultaneously. Finally, the intervals between lines are determined using the deviation and the reading of the laser interferometer. The calibration process is performed automatically after the installation of the tape. The estimated expanded uncertainty of the steel tape measurement is √((24 μm)2 + (6.6×10-6)2×L2) at the confidence level of approximately 95%. (technical design note)

    The small Near-Earth Asteroids (NEAs) represent a potential risk but also an easily accessible space resource for future robotic or human in-situ space exploration or commercial activities. However, the population of 1--300 m NEAs is not well understood in terms of size- frequency and orbital distribution. NEAs with diameters below 200 m tend to have much faster spin rates than large objects and they are believed to be monolithic and not rubble-pile like their large counterparts. Moreover, the current surveys do not systematically search for the small NEAs that are mostly overlooked. We propose a low- cost robotic optical survey (ADAM-WFS) aimed at small NEAs based on four state-of-the-art telescopes having extremely wide fields of view. The four Houghton-Terebizh 30-cm astrographs (Fig. left) with 4096×4096 -pixel CCD cameras will acquire 96 square degrees in one exposure with the plate scale of 4.4 arcsec/pixel. In 30 seconds, the system will be able to reach +17.5 mag in unfiltered mode. The survey will be operated on semi-automatic basis, covering the entire night sky three times per night and optimized toward fast moving targets recognition. The advantage of the proposed system is the usage of existing of-the-shelf components and software for the image processing and object identification and linking (Denneau et al., 2013). The one-year simulation of the survey (Fig. right) at the testing location at AGO Modra observatory in Slovakia revealed that we will detect 60--240 NEAs between 1--300 m that get closer than 10 lunar distances from the Earth. The number of detections will rise by a factor of 1.5--2 in case the survey is placed at a superb observing location such as Canary Islands. The survey will also serve as an impact warning system for imminent impactors. Our simulation showed that we have a 20 % chance of finding a 50-m NEA on a direct impact orbit. The survey will provide multiple byproducts from the all-sky scans, such as comet discoveries, sparse

  9. Survey and analysis of radiation safety management systems at medical institutions. Second report. Radiation measurement, calibration of radiation survey meters, and periodic check of installations, equipment, and protection instruments

    International Nuclear Information System (INIS)

    We carried out a questionnaire survey to determine the actual situation of radiation safety management measures in all medical institutions in Japan that had nuclear medicine facilities. The questionnaire consisted of questions concerning the evaluation of shielding capacity; radiation measurement; periodic checks of installations, equipment, and protection instruments; and the calibration of radiation survey meters. The analysis was undertaken according to region, type of establishment, and number of beds. The overall response rate was 60 percent. For the evaluation of shielding capacity, the outsourcing rate was 53 percent of the total. For the radiation measurements of ''leakage radiation dose and radioactive contamination'' and contamination of radioactive substances in the air'', the outsourcing rates were 28 percent and 35 percent of the total, respectively (p<0.001, according to region and establishment). For the periodic check of radiation protection instruments, the implementation rate was 98 percent, and the outsourcing rate was 32 percent for radiation survey meters and 47 percent for lead aprons. The non-implemented rate for calibration of radiation survey meters was 25 percent of the total (p<0.001, according to region and establishment). The outsourcing rate for calibration of radiation survey meters accounted for 87 percent of the total, and of these medical institutions, 72 percent undertook annual calibration. The implementation rate for patient exposure measurement was 20 percent of the total (p<0.001, according to number of beds), and of these medical institutions 46 percent recorded measurement outcome.

  10. Detection of the surface contamination with nuclides emitting low-energy β-rays by direct measurement method using a GM survey-meter

    International Nuclear Information System (INIS)

    For a direct measurement method using a GM survey-meter, the detection efficiency and detection limit against surface contamination with nuclides emitting β-rays on a polyethylene-coated paper were examined. Three nuclides, 14C, 35S and 32P were used as a source. The detection efficiency against 14C, 35S and 32P at the place of 5.0 mm distance from the detection face of the survey-meter was approximately 1.4, 1.9 and 34.5%, respectively. Although the detection efficiency obtained for 32P was the same as the value showed in the instruction manual, that of 14C was smaller than that of the instruction manual. It is considered that such a difference in detection efficiency between 32P and 14C is ascribed to difference in source efficiency. Furthermore the detection limit against 14C, 35S and 32P at the distance of 5.0 mm was about 3.6, 2.6 and 0.2 Bq/cm2, respectively. Hence it appears that the direct measurement method using the GM survey-meter is useful to check the surface contamination with 14C or 35S in a controlled area since the surface contamination density limit in a controlled area is 40 Bq/cm2.

  16. AUTOMATIC UNSUPERVISED CLASSIFICATION OF ALL SLOAN DIGITAL SKY SURVEY DATA RELEASE 7 GALAXY SPECTRA

    International Nuclear Information System (INIS)

    Using the k-means cluster analysis algorithm, we carry out an unsupervised classification of all galaxy spectra in the seventh and final Sloan Digital Sky Survey data release (SDSS/DR7). Except for the shift to rest-frame wavelengths and the normalization to the g-band flux, no manipulation is applied to the original spectra. The algorithm guarantees that galaxies with similar spectra belong to the same class. We find that 99% of the galaxies can be assigned to only 17 major classes, with 11 additional minor classes including the remaining 1%. The classification is not unique since many galaxies appear in between classes; however, our rendering of the algorithm overcomes this weakness with a tool to identify borderline galaxies. Each class is characterized by a template spectrum, which is the average of all the spectra of the galaxies in the class. These low-noise template spectra vary smoothly and continuously along a sequence labeled from 0 to 27, from the reddest class to the bluest class. Our Automatic Spectroscopic K-means-based (ASK) classification separates galaxies in colors, with classes characteristic of the red sequence, the blue cloud, as well as the green valley. When red sequence galaxies and green valley galaxies present emission lines, they are characteristic of active galactic nucleus activity. Blue galaxy classes have emission lines corresponding to star formation regions. We find the expected correlation between spectroscopic class and Hubble type, but this relationship exhibits a high intrinsic scatter. Several potential uses of the ASK classification are identified and sketched, including fast determination of physical properties by interpolation, classes as templates in redshift determinations, and target selection in follow-up works (we find classes of Seyfert galaxies, green valley galaxies, as well as a significant number of outliers). The ASK classification is publicly accessible through various Web sites.

    1983-06-01

    During the period of 22-28 July, 1978, five dives were made in the manned submersible ALVIN into the Atlantic Ocean 3800 meter depth radioactive waste disposal site located in the Hudson Canyon channel approximately 320 kilometers from the Maryland-Delaware coast. A geological description of the site was made by direct examination of the bottom topography, bedrock exposures, sedimentary and erosional processes, and sediment cores collected from the dumpsite area. Observations within a depth range of 3985-3830 meters revealed angular blocks and piles of displaced channel wall rock, boulder and cobble olistoliths of Eocene-age chalks derived from higher elevations on the slope, and bedforms such as ripples and scour marks which imply the existence of periodic strong currents. Local benthic fauna were sparse. Three low-level radioactive waste drums were examined from the submersible, and one was subsequently recovered for corrosion, and concrete deterioration analyses. Photographic and visual evidence suggest that downslope transport of objects such as talus blocks, olistoliths, and radioactive waste drums has occurred in this area.

    Full Text Available The electricity is very essential in day to day life. Most of industries are running with electricity. In commercial areas also electricity plays very vital role and hence electricity is backbone of any developing nation. To measure the consumed electricity and generate Electricity bill, the energy meters are provided to each and every consumer. This project is use to take meter reading wirelessly by using transceiver which provides accuracy and speed in MSEB meter reading. In this work, Micro controller plays the main role. This circuit contains the LCD, RF transmitter, RF receiver, Energy meter, switch, RS 232 etc. This project uses one Microcontroller, LCD, RF transceiver module, energy meter and relay for connecting load. Meter reading is the technology of automatically collecting data from energy meter and transferring that data to a central database for billing and/or analyzing. This saves employee trips and means that billing can be based on actual consumption rather than on an estimate based on previous consumption, giving customers better control of their use of electric energy. The Transmitter is connected to the meter and it counts the pulses from it and displays it over the LCD. It transmits the data over radio frequency. This network technology overcome all the difficulties of earlier billing system and become more advantageous and accurate.

    We present an automatic method to identify galaxy mergers using the morphological information contained in the residual images of galaxies after the subtraction of a Sersic model. The removal of the bulk signal from the host galaxy light is done with the aim of detecting the fainter minor mergers. The specific morphological parameters that are used in the merger diagnostic suggested here are the Residual Flux Fraction and the asymmetry of the residuals. The new diagnostic has been calibrated and optimized so that the resulting merger sample is very complete. However, the contamination by non-mergers is also high. If the same optimization method is adopted for combinations of other structural parameters such as the CAS system, the merger indicator we introduce yields merger samples of equal or higher statistical quality than the samples obtained through the use of other structural parameters. We explore the ability of the method presented here to select minor mergers by identifying a sample of visually classif...

    A dense digital surface model is one of the products generated by using UAV aerial survey data. Today more and more specialized software are supplied with modules for generating such kind of models. The procedure for dense digital model generation can be completely or partly automated. Due to the lack of reliable criterion of accuracy estimation it is rather complicated to judge the generation validity of such models. One of such criterion can be mobile laser scanning data as a source for the detailed accuracy estimation of the dense digital surface model generation. These data may be also used to estimate the accuracy of digital orthophoto plans created by using UAV aerial survey data. The results of accuracy estimation for both kinds of products are presented in the paper.

  5. Characterization of various survey meters through car-borne survey in Java Island as a basis data for searching orphan sources

    International Nuclear Information System (INIS)

    Full text: An assessment of available technical means has been performed to select suitable instruments to be used in car borne surveys for the detection and localization of orphan sources. Criteria used for the selection included (i) that the instrument should be simple to operate, (ii) that it should provide reliable results, and (iii) that little time for processing or transferring raw data from the instrument to a desktop computer (for decision making using statistical methods) is required. Based upon these criteria, four hand-held instruments in the BATAN inventory were selected for further study. Measurements data using these four instruments, taken during a 400 km car-borne survey of western Java, was analyzed. The data was taken both in rainy and clear weather conditions, thus recorded fluctuations from the instrument response (when the vehicle was driven along the same paths in both weather conditions) included variations due washout by the rain of Rn daughters. The data from all instruments was analyzed using various statistical tests to determine the most sensitive instruments (with lowest number of alarm fluctuations) and best statistical analysis technique for finding anomalous radiation levels. Using this data, as well as data from taken during controlled field measurements, it was determined that the best instrument could detect a 7.4 GBq 137Cs source from as far as 145 m away, when traveling in a car at 50 kph.

    1276 shoeprints were collected at a scientific exhibition. Details regarding the age groups of the participants, style, size and manufacturer/brand of their shoes were recorded. The impressions were assigned to pattern groups showing that the most common pattern was present in only 1% of the population studied and most patterns were much less common. The impressions were digitized and a system developed for automatically sorting a database of images of outsole patterns in response to a reference image. The database images are ranked so that those from the same pattern group as the reference shoeprint are likely to be at the start of the list. A database of 486 complete shoeprint images belonging to 142 pattern groups was established with each group containing two or more examples. Tests of the system have shown that the first-ranked database image belongs to the same pattern group as the reference image 60% of the time and that a correct match appears within the first 5% of the ranked images 88% of the time. The system has translational and rotational invariance so that the spatial positioning of the reference shoeprint images does not have to correspond with the spatial positioning of the shoeprint images of the database. The performance of the system for matching partial shoeprints was also determined. PMID:17002210

When DPC was experiencing diminished service within its analog cellular-based data communications system, it was presented with an opportunity to install a new automated telecommunications system that would provide secure collection of meter readings from all of its substations. DPC decided to evaluate an advanced multifunctional digital meter from Schweitzer Engineering Laboratories (SEL). The SEL-734 Revenue Metering System offers complete instantaneous metering functions, including voltages, currents, power, energy and power factor. Other capabilities include predictive demand, time-of-use metering, automatic voltage monitoring, harmonics metering and synchrophasor measurement. From a metering perspective, DPC wanted to perform daily load profiles and interval-by-interval metering of their delivery points for billing purposes. They also wanted to provide real-time monitoring of electricity being delivered for both generation and transmission purposes and to make that information available to a distribution SCADA system for their members. The SEL-734 Revenue Meter was well suited to those needs. The SEL-734 provides very high-accuracy energy metering, load profile data collection, instantaneous power measurements, power quality monitoring, and communicates simultaneously over a modem, serial ports, and wide area networks (WAN). The meter is backed with a ten-year warranty as well as field support engineers. 5 figs.

    We employ classical statistical methods of multivariate classification for the exploitation of the stellar content of the Hamburg/ESO objective prism survey (HES). In a simulation study we investigate the precision of a three-dimensional classification (Teff, log g, [Fe/H]) achievable in the HES for stars in the effective temperature range 520010 (typically corresponding to B_J<16.5). The accuracies in log g and [Fe/H] are better than 0.68dex in the same S/N range. These precisions allow for a very efficient selection of metal-poor stars in the HES. We present a minimum cost rule for compilation of complete samples of objects of a given class, and a rejection rule for identification of corrupted or peculiar spectra. The algorithms we present are being used for the identification of other interesting objects in the HES data base as well, and they are applicable to other existing and future large data sets, such as those to be compiled by the DIVA and GAIA missions.

    The Transneptunian Automated Occultation Survey (TAOS II) is a three robotic telescope project to detect the stellar occultation events generated by Trans Neptunian Objects (TNOs). TAOS II project aims to monitor about 10000 stars simultaneously at 20Hz to enable statistically significant event rate. The TAOS II camera is designed to cover the 1.7 degree diameter field of view (FoV) of the 1.3m telescope with 10 mosaic 4.5kx2k CMOS sensors. The new CMOS sensor has a back illumination thinned structure and high sensitivity to provide similar performance to that of the backillumination thinned CCDs. The sensor provides two parallel and eight serial decoders so the region of interests can be addressed and read out separately through different output channels efficiently. The pixel scale is about 0.6"/pix with the 16μm pixels. The sensors, mounted on a single Invar plate, are cooled to the operation temperature of about 200K by a cryogenic cooler. The Invar plate is connected to the dewar body through a supporting ring with three G10 bipods. The deformation of the cold plate is less than 10μm to ensure the sensor surface is always within ±40μm of focus range. The control electronics consists of analog part and a Xilinx FPGA based digital circuit. For each field star, 8×8 pixels box will be readout. The pixel rate for each channel is about 1Mpix/s and the total pixel rate for each camera is about 80Mpix/s. The FPGA module will calculate the total flux and also the centroid coordinates for every field star in each exposure.

    2002-01-01

    Those who work in radiation protection are faced with various quantities that were created to account for the effects of ionizing radiation in the human body. As far as the experimental point of view is concerned, each available equipment is planned to measure a distinct quantity, for a specific radiation protection application, and it is not always clear which one it is. This paper shows a series of tests, planned and applied to a portable gamma ray spectrometer, in order to assure that the monitoring low dose levels of radiation with it is reliable. The equipment is fully automated and does not allow modifications of the conversion factors from counts to ambient dose equivalent. It is therefore necessary to assure that the values provided by the equipment are correct and refer to the actual situation one expects to find in practice. The system is based on an NaI(Tl) scintillation detector, mounted with its electronics in a portable case, suitable for field measurements. It measures ambient dose equivalent r...

  12. Integrated metering products

    International Nuclear Information System (INIS)

    During the last 10 years the U.K. in particular has become increasingly interested in the introduction of solid state products within the metering market. Whilst this trend has not been seen in the rest of Europe, the U.K. market has made great strides within the domestic single phase metering area. Of course polyphase precision meters have been with us for many years although it must be stated that the high manufacturing cost of these products have not made them attractive for general use. Today, the solid state domestic meter makes up some 40% of the total U.K. market and it is anticipated that this growth will continue for many years to come. Indeed some electricity companies will now only purchase solid state domestic metering products. It is clear that the major benefits which accrue from solid state metering and in particular from integrated metering products ensure that the trend outlined will continue. The two major benefits which are worth considering are cost and additional functionality. (author)

    Hargrove, Douglas L.

    2004-09-14

    A portable, hand-held meter used to measure direct current (DC) attenuation in low impedance electrical signal cables and signal attenuators. A DC voltage is applied to the signal input of the cable and feedback to the control circuit through the signal cable and attenuators. The control circuit adjusts the applied voltage to the cable until the feedback voltage equals the reference voltage. The "units" of applied voltage required at the cable input is the system attenuation value of the cable and attenuators, which makes this meter unique. The meter may be used to calibrate data signal cables, attenuators, and cable-attenuator assemblies.

    The apparatus described is designed for measuring {beta}-emitting elements by the absorption method; it is suitable for carrying out a large number of routine analyses. A mechanical device pushes an aluminium absorption set automatically between the source and the detector; the movement is programmed for cutting on and off by a transistorized electronic unit, with printing out and punching of the results on tape; then this can be mathematically processed by a computer (tracing of absorption spectra, extrapolation and calculation of the activity). The detector is either a {beta}-probe or a proportional counter with a specially designed loop. For routine measurements, the accuracy obtained, with all corrections made, is from 5 to 8 per cent; the reproducibility is about 2 per cent. (authors) [French] L'appareillage decrit est destine aux mesures des elements emetteurs {beta} par la methode d'absorption et il permet d'effectuer, en routine, un nombre important de mesures. Un ensemble mecanique effectue le passage automatique, sous vide primaire, d'un jeu d'absorption en aluminium entre la source et le detecteur, ce passage est programme en pre-temps ou pre-coup par un ensemble electronique a transistors, avec impression et perforation sur bandes des resultats des mesures pour traitement mathematique par un ordinateur (trace du spectre d'absorption, extrapolation et calcul d'activite).

  19. Automatic sequences

    CERN Document Server

    Haeseler, Friedrich

    2003-01-01

    Automatic sequences are sequences which are produced by a finite automaton. Although they are not random they may look as being random. They are complicated, in the sense of not being not ultimately periodic, they may look rather complicated, in the sense that it may not be easy to name the rule by which the sequence is generated, however there exists a rule which generates the sequence. The concept automatic sequences has special applications in algebra, number theory, finite automata and formal languages, combinatorics on words. The text deals with different aspects of automatic sequences, in particular:· a general introduction to automatic sequences· the basic (combinatorial) properties of automatic sequences· the algebraic approach to automatic sequences· geometric objects related to automatic sequences.

  20. Survey of energetic particle precipitation. Automatic detection of enhanced transient ionisation in the mesosphere using subionospheric narrow band VLF signals

    International Nuclear Information System (INIS)

    Complete text of publication follows. Powerful signals of VLF transmitters, propagating long range in the Earth-ionosphere waveguide have been widely applied as effective tools for monitoring transient mesospheric ionization. Perturbations in recorded amplitude and/or phase data series may refer to the effect of. loss-cone precipitation of trapped energetic electrons (Carpenter et al., 1984, Dowden and Adams, 1990), burst of solar plasma particles (Clilverd et al., 2001). The contribution of precipitating particles are thought to be substantial in certain Sun-to-Earth energy flow processes in the upper atmosphere (Rodger et al., 2005). Hungarian narrow band VLF measuring network has been operated in Hungary in the last decade almost continuously, dedicated to monitor ionization enhancement regions along numerous transmitter-receiver paths. This setup is based on Omnipal and Ultra-MSK equipment, logging amplitude and phase data of received signals, sampled at frequencies of selected VLF transmitters. Signal trajectories, selected for recording represent proper configuration to survey transient ionization caused by energetic particles in the sub-polar region, such as effect of scattered particles of the inner radiation belt. Data processing results in the mass archived VLF recordings is presented based on an automated event detection procedure, developed recently. Occurrence rates, daily and seasonal variation, statistics of transient ionization enhancements, their geographic distribution within the surveyed range and time period are the primal outcome of this analysis.

    2016-03-01

    Full Text Available Prepaid meter (PM is getting very popular especially in developing countries. There are many advantages to use prepaid meter as opposed to postpaid meter both to the utility provider and to the consumer. Brunei has adopted PM but it is not intelligent and not wireless enabled. Reading meters and topping up balance are still done manually. Utility provider does not have information on the usage statistics and has only limited functionalities in the grid control. So accordingly an intelligent agent based wireless prepaid energy meter been developed using JADE-LEAP Agent development kit allowing agent from utility provider to query wireless energy meter for energy values for every household. These statistics can be used for statistical computation of the power consumed and for policy and future planning. Agent from consumers’ mobile devices can query the energy meter to study the power consumed and for topping up the balance. When the meter reaches the threshold, agent at energy meter would also send messages to alert consumers for topping up through mobile handset and failing to do so will lead to power being cut automatically

    International Nuclear Information System (INIS)

    This report describes the survey operation, survey and processing methods and the deliverables of an aerogeophysical survey in Olkiluoto area in April 2008. The survey was conducted by Geological Survey of Finland (GTK). The survey aircraft was a twin-engine Twin Otter operated by Finnish Aviation Academy (SIO) and owned by Natural Environment Research Council / British Geological Survey (NERC / BGS), with whom GTK has established a joint venture called Joint Airborne-geoscience Capability (JAC). The survey was conducted in April 2008 during six days. The survey consists of six separate survey flights, one of which was a magnetic calibration flight. The survey was based in Pori airport. Survey line spacing was 50 meters and nominal survey altitude was 30 meters. Measurements were completed in April 2008, and data processing and reporting was done in June 2008. Two cesium magnetometers installed onboard the aircraft (at the left wingtip and in a nose cone) were measuring the magnetic total field intensity during the survey flights. An automatic compensation unit corrected the aircraft attitude errors in the magnetic data in real time. In addition to magnetic measurement, auxiliary parameters such as flight altitude and aircraft attitude were also recorded simultaneously. Reference ground base station was used for recording the temporal variations in the magnetic field and also reference data for post-positioning of coordinate information. In the post-processing phase, heading correction, base station correction and microlevelling procedures were applied to the magnetic data. The data was exported to numeric XYZ files and interpolated into grid data file. A noteworthy local detail present in the survey and in the processing was the massive power line. For safety reasons, flight altitude had to be increased and survey lines had to be cut short in the vicinity of the powerline. However, due to reasonable planning of the survey area boundaries, this caused no great

  6. Digital Receiver Phase Meter

    Science.gov (United States)

    Marcin, Martin; Abramovici, Alexander

    2008-01-01

    The software of a commercially available digital radio receiver has been modified to make the receiver function as a two-channel low-noise phase meter. This phase meter is a prototype in the continuing development of a phase meter for a system in which radiofrequency (RF) signals in the two channels would be outputs of a spaceborne heterodyne laser interferometer for detecting gravitational waves. The frequencies of the signals could include a common Doppler-shift component of as much as 15 MHz. The phase meter is required to measure the relative phases of the signals in the two channels at a sampling rate of 10 Hz at a root power spectral density digital receiver. The input RF signal is first fed to the input terminal of an analog-to-digital converter (ADC). To prevent aliasing errors in the ADC, the sampling rate must be at least twice the input signal frequency. The sampling rate of the ADC is governed by a sampling clock, which also drives a digital local oscillator (DLO), which is a direct digital frequency synthesizer. The DLO produces samples of sine and cosine signals at a programmed tuning frequency. The sine and cosine samples are mixed with (that is, multiplied by) the samples from the ADC, then low-pass filtered to obtain in-phase (I) and quadrature (Q) signal components. A digital signal processor (DSP) computes the ratio between the Q and I components, computes the phase of the RF signal (relative to that of the DLO signal) as the arctangent of this ratio, and then averages successive such phase values over a time interval specified by the user.

  12. Automatic readout micrometer

    International Nuclear Information System (INIS)

    A measuring system is disclosed for surveying and very accurately positioning objects with respect to a reference line. A principal use of this surveying system is for accurately aligning the electromagnets which direct a particle beam emitted from a particle accelerator. Prior art surveying systems require highly skilled surveyors. Prior art systems include, for example, optical surveying systems which are susceptible to operator reading errors, and celestial navigation-type surveying systems, with their inherent complexities. The present invention provides an automatic readout micrometer which can very accurately measure distances. The invention has a simplicity of operation which practically eliminates the possibilities of operator optical reading error, owning to the elimination of traditional optical alignments for making measurements. The invention has an extendable arm which carries a laser surveying target. The extendable arm can be continuously positioned over its entire length of travel by either a coarse or fine adjustment without having the fine adjustment outrun the coarse adjustment until a reference laser beam is centered on the target as indicated by a digital readout. The length of the micrometer can then be accurately and automatically read by a computer and compared with a standardized set of alignment measurements. Due to its construction, the micrometer eliminates any errors due to temperature changes when the system is operated within a standard operating temperature range

    Science.gov (United States)

    Kunickis, M.; Dandens, A.; Bariss, U.

    2015-12-01

    Automatic data reading from smart meters is being developed in many parts of the world, including Latvia. The key drivers for that are developments of smart technologies and economic benefits for consumers. Deployment of smart meters could be launched in a massive scale. Several pilot projects were implemented to verify the feasibility of smart meters for individual consumer groups. Preliminary calculations indicate that installation of smart meters for approximately 23 % of electricity consumers would be economically viable. Currently, the data for the last two years is available for an in-depth mathematical analysis. The continuous analysis of consumption data would be established, when more measurements from smart meters are available. The extent of introduction of smart meters should be specified during this process in order to gain the maximum benefit for the whole society (consumers, grid companies, state authorities), because there are still many uncertain and variable factors. For example, it is necessary to consider statistical load variations by hour, dependence of electricity consumption on temperature fluctuations, consumer behaviour and demand response to market signals to reduce electricity consumption in the short and long term, consumer's ambitions and capability to install home automation for regulation of electricity consumption. To develop the demand response, it is necessary to analyse the whole array of additional factors, such as expected cost reduction of smart meters, possible extension of their functionality, further development of information exchange systems, as well as standard requirements and different political and regulatory decisions regarding the reduction of electricity consumption and energy efficiency.

Details of six tasks are given and cover examination of the existing framework and legal documentation for metering work, the existing technical requirements for meter operators, meter operator personnel accreditation, appraisal of options for meter changes and for micro-generation installation, document change procedures, industry consultation, and a review of the costs implications of the options.

  1. Revenue Recovery Through Meter Replacement

    OpenAIRE

    Shields, Devan J.

    2011-01-01

    Previous studies have identified water meter inaccuracy at low flow rates as a significant source of non-revenue flow for water systems; however a lack of available data makes it difficult to include low flow accuracy degradation in meter replacement plans. This thesis examines results from an extensive accuracy test program carried out at the Utah Water Research Laboratory on small water meters over a wide range of flow rates and at various levels of throughput. The study compares expected a...

A market survey showed that Coriolis and thermal mass flow meters and positive displacement (volumetric) flow meters, as the Reciflow, are the most common kinds. The Reciflow consist of a syst...

  4. Digital reactivity meter

    International Nuclear Information System (INIS)

    Digital reactivity meters (DRM) are mostly used as measuring instruments, e.g. for calibration of control rods, and there are only a few cases of their incorporation into the control systems of the reactors. To move in this direction there is more development work needed. First of all, fast algorithms are needed for inverse kinetics equations to relieve the computer for more important tasks of reactor model solving in real time. The next problem, currently under investigation, is the incorporation of the reactor thermal-hydraulic model into the DRM so that it can be used in the power range. Such an extension of DHM allows presentation not only of the instantaneous reactivity of the system, but also the inserted reactivity can be estimated from the temperature reactivity feed-backs. One of the applications of this concept is the anomalous digital reactivity monitor (ADRN) as part of the reactor protection system. As a solution of the first problem, a fast algorithm for solving the inverse kinetics equations has been implemented in the off-line program RODCAL on CDC 1700 computer and tested for its accuracy by performing different control rod calibrations on the reactor TRIGA

  10. Calibration of personnel dose meters

    International Nuclear Information System (INIS)

    Methods of calibrating both film and thermoluminescent dose meters (TLD) to photon and electron radiations are described. K fluorescent X-rays, heavily filtered X-ray beams, and isotope gamma rays are used at the Los Alamos calibration facility to measure the energy and angular response of radiation detectors over a photon energy range of 10 to 1000keV. Beam spectra, alignment, size and uniformity are discussed. The energy and angular response of dose meters to electrons is measured with beta-emitting isotopes varying in maximum energy from 770 to 2300keV. A free-air ionization chamber is the primary standard used in the measurement of photon radiation. Thimble-sized ionization chambers, calibrated to the free-air chamber, serve as secondary standards. Electron radiation is measured with an end-window ionization chamber having a 7mg/cm2 approximately tissue-equivalent plastic wall. Photon calibrations are performed with personnel dose meters in air, on a phantom, and in a phantom. If the personnel dose meter and secondary chamber are both in air, or both on or both in a phantom, the response of the LiF TLD chip, relative to the secondary chamber, is the same. However, the film dose meter shows a larger relative response on or in the phantom than in air. With beta sources, personnel dose meters are calibrated by exposing the dose meter either in air to a high-dose-rate 90Sr (90Y) source, or in contact with a low-dose-rate uranium source. The differences in personnel dose meter response observed between the two methods are discussed. The personnel dose meters are calibrated to determine penetrating doses by placing the secondary chamber 1cm deep in a phantom and the personnel dose meter on the surface, with a filter over the TLD to simulate 1cm depth. Non-penetrating dose calibrations are measured by placing both chamber and dose meter on the surface of the phantom. (author)

  15. X-ray system signal derivation circuits for heat unit indicators and/or calibration meters

    International Nuclear Information System (INIS)

    Milliampere and kilovolt signals are monitored from the X-ray tube system high tension transformer. These signals may be connected to a heat unit indicator or a calibration meter or both. With the heat unit indicator, the heat level in an X-ray tube anode is monitored and referred to the level corresponding to the ambient room temperature as zero reference. As successive signal exposures or series of exposures are made, the X-ray tube heat loading is automatically monitored and displayed. The cooling characteristics of the tube are automatically reflected in the reading. A calibration meter may be connected to the signal derivation circuitry to indicate a plurality of operating parameters. The circuitry includes automatic scaling device for maintaining the relatively accurate signals required for the accurate operation of the heat indicator and the calibration meter. (UK)

  9. Sulfur meter speeds coal blending

    International Nuclear Information System (INIS)

    The sulfur content has become the most important criterion that industry looks at when purchasing coal. The exact amount of sulfur in coal being processed by a preparation plant must be known and, if possible, controlled by blending coal streams of various sulfur contents. Present techniques, however, of measuring the sulfur in coal involve laborious and time-consuming sampling and chemical analysis (12 to 24 hr), and the results usually are not available until the following day. By then, the coal barges or trains are already on the way to their destinations. A new nuclear sulfur meter is expected to overcome these difficulties and help lead to true automation in coal preparation plants. Initially developed by the Bureau of Mines' Morgantown Energy Research Center (MERC) at Morgantown, W. Va., and completed after reorganization of the center by the US Energy Research and Development Administration (ERDA), the meter can scan coal to produce a reading within 2 min to an accuracy of 0.04 percent sulfur. The meter is expected to soon result in an element-ash-moisture-Btu meter that would rapidly detect the sulfur, sodium, potassium, and overall mineral content of the coal, as well as its ash and Btu content

    Introduction of communication technologies into today's energy network enables the interworking between the domains of smart metering, smart grid, smart home and e-mobility as well as the creation and provisioning of new innovative services such as efficient load adjustment. Due to this convergence the new energy networks are becoming increasingly complex. Ensuring the interworking between all network elements (e.g. electricity meters, gateways) in these smart energy networks is of utmost importance. To this end conformance and interoperability tests have to be defined to ensure that services work as expected. (orig.)

This test range was designed to duplicate typical field survey conditions encountered in gravity measurements on 3-D land seismic surveys. A profile of 270 stations was acquired with a station spacing of 33.5 m (110 ft). The four meters were Scintrex CG-3, Sodin, LaCoste and Romberg (L and R) G-meter, and Edcon/L and R Super-G meter. The purpose of this study was to determine which of the four meters had the best balance of accuracy, convenience, and speed of measurement for these specialized surveys. All four meters had their limitations, and no single meter was greatly superior to the others. The CG-3 was awkward in leveling, had a large (368 {mu}Gal per day) drift rate, and had some quirks in its user interface. The Sodin meter had problems controlling its temperature and, at one point, had a very high 935 {mu}Gal per day drift rate. It had the poorest accuracy of the four. The G-meter lacked a convenient digital user interface; thus, it was susceptible to operator blunder in misreading or recording the data. The Super-G meter also had some problems in its user interface, had only a 6-mGal range without a range change, and was the heaviest of the field instruments. An unbiased statistical estimator was developed to analyze the data. The technique determined the best three meters at each station. Both the G-meter and the Super-G meter produced the most accurate data. They had an average absolute deviation from the mean of 209 and 23 {mu}Gal, respectively. In comparison, the two quartz meters--the CG-3 and the Sodin--had an average absolute deviation from the mean of 31 and 46 {mu}Gal, respectively. The authors would like to see the manufacturers improve (or add, in the case of the G-meter and the Sodin) their digital interfaces. Additionally, they would like to see upgrades in the thermal control systems in all the meters. The single largest amount of station time was

    Full Text Available The paper deals with the construction and determination of coordinates of the absoluteEDMs baseline in a laboratory with 16 pillars with forced centring. Leica Absolute TrackerAT401 (standard deviation of distance measurement: 5 μ m, standard deviation of anglemeasurement: 0.15 mgon, which is designed for very accurate industrial measurements,was used for our purpose. Lengths between the baseline points were determined with astandard deviation of 0.02 mm. The baseline is used for determining systematic and randomerrors of distance meters and for accuracy of distance meters at short distances commonin engineering surveying for purposes of mechanical engineering.

  13. Automatic personnel contamination monitor

    International Nuclear Information System (INIS)

    United Nuclear Industries, Inc. (UNI) has developed an automatic personnel contamination monitor (APCM), which uniquely combines the design features of both portal and hand and shoe monitors. In addition, this prototype system also has a number of new features, including: micro computer control and readout, nineteen large area gas flow detectors, real-time background compensation, self-checking for system failures, and card reader identification and control. UNI's experience in operating the Hanford N Reactor, located in Richland, Washington, has shown the necessity of automatically monitoring plant personnel for contamination after they have passed through the procedurally controlled radiation zones. This final check ensures that each radiation zone worker has been properly checked before leaving company controlled boundaries. Investigation of the commercially available portal and hand and shoe monitors indicated that they did not have the sensitivity or sophistication required for UNI's application, therefore, a development program was initiated, resulting in the subject monitor. Field testing shows good sensitivity to personnel contamination with the majority of alarms showing contaminants on clothing, face and head areas. In general, the APCM has sensitivity comparable to portal survey instrumentation. The inherit stand-in, walk-on feature of the APCM not only makes it easy to use, but makes it difficult to bypass.

    Forsen, H.; Tarvainen, V. [VTT Building Technology, Espoo (Finland). Building Materials and Products, Wood Technology

    2000-09-01

    The main task of VTT in this EU project was to test and improve the reliability and performance of moisture content meters. A total of 16 resistance type and 6 capacitance type hand-held moisture meters were included in the test series. Test samples of the most important European species (pine, spruce, birch, oak, beech, alder, larch) were obtained from all over Europe. The total survey included about 2,700 pieces for comparative testing. The test material was conditioned to three different moisture contents (8 - 10%, 12 - 14% and 16 - 18%). The moisture gradients in the test specimens were small due to the long conditioning time lasting at least 1 year. The effects of various factors, such as moisture content, species, and temperature, on the electrical resistance of conditioned wood were studied. In the laboratory tests, the resistance - moisture content curves for different species from different countries were determined using conditioned wood material. The species corrections (resistance curves) are quite similar for different counties. Only the resistance curve for Maritime Pine differs clearly from the other resistance curves for the pine species originating from the different countries. The wood temperature corrections are about 0.1 - 0.15% units/deg C which has to be considered when the moisture content of wood is measured at temperatures other than 20 deg C. The other properties of wood, such as sapwood/heartwood and density, do not have a significant effect on resistance values. There were no significant resistance differences related to the type of electrodes, distances between electrodes, and different measuring direction. The commercial instruments for the determination of wood moisture content were tested with respect to accuracy, reliability and ergonomy. The moisture meters were tested both under laboratory and industrial conditions. Most of the resistance meters show a systematic deviation from the actual moisture content because of incorrect MC

    We examined the influence of incidental exposure to varied metrical patterns from different musical cultures on the perception of complex metrical structures from an unfamiliar musical culture. Adults who were familiar with Western music only (i.e., simple meters) and those who also had limited familiarity with non-Western music were tested on their perception of metrical organization in unfamiliar (Turkish) music with simple and complex meters. Adults who were familiar with Western music detected meter-violating changes in Turkish music with simple meter but not in Turkish music with complex meter. Adults with some exposure to non-Western music that was unmetered or metrically complex detected meter-violating changes in Turkish music with both simple and complex meters, but they performed better on patterns with a simple meter. The implication is that familiarity with varied metrical structures, including those with a non-isochronous tactus, enhances sensitivity to the metrical organization of unfamiliar music.

  9. Net metering in British Columbia : white paper

    International Nuclear Information System (INIS)

    Net metering was described as being the reverse registration of an electricity customer's revenue meter when interconnected with a utility's grid. It is a provincial policy designed to encourage small-distributed renewable power generation such as micro-hydro, solar energy, fuel cells, and larger-scale wind energy. It was noted that interconnection standards for small generation is an important issue that must be addressed. The British Columbia Utilities Commission has asked BC Hydro to prepare a report on the merits of net metering in order to support consultations on a potential net metering tariff application by the utility. This report provides information on net metering with reference to experience in other jurisdictions with net metering, and the possible costs and benefits associated with net metering from both a utility and consumer perspective. Some of the barriers and policy considerations for successful implementation of net metering were also discussed. refs., tabs., figs

  15. Smart meter status report from Toronto

    International Nuclear Information System (INIS)

    An update of Toronto Hydro's smart metering program was presented. Electricity demand is expected to keep increasing, and there is presently insufficient generation to match supply needs in Ontario. The smart metering program was introduced to aid in the Ontario government's energy conservation strategy, as well as to address peak supply problems that have led to power outages. It is expected that the smart metering program will reduce provincial peak supply by 5 per cent, as the meters support both time-of-use rates and critical peak pricing. Over 800,000 smart meters will be supplied to customers by 2007, and all 4.3 million homes in Toronto will have a smart meter by 2010. In order to meet targets for 2010, the utility will continue to install more 15,000 meters each month for the next 4 years. While the Ontario government has planned and coordinated the rollout and developed smart metering specifications and standards, Toronto Hydro is responsible for the purchase, installation, operation and maintenance of the meters. Advance testing of each meter is needed to ensure billing accuracy, and customer education on meter use is also. The complexity of the metering program has led the utility to establish a rigid project management process. Customer education pilot program are currently being conducted. Experience gained during the earlier phases of the program have enabled the utility to select appropriate metering systems based on density, topography and physical conditions. Project expenditures have been within budget due to improved project estimating and planning. The metering program has been conducted in tandem with the utility's peakSAVER program, a residential and small commercial load control program that has been successful in reducing summer peak demand by cycling air conditioners without causing discomfort. It was concluded that the utility will continue with its mass deployment of smart meters, and is currently preparing its call center to handled

    THE STUDY EVALUATED AND COMPARED THE DIFFERENCES OF GLUCOSE RESPONSES, INCREMENTAL AREA UNDER CURVE (IAUC), GLYCEMIC INDEX (GI) AND THE CLASSIFICATION OF GI VALUES BETWEEN MEASURED BY BIOCHEMICAL ANALYZER (FUJI AUTOMATIC BIOCHEMISTRY ANALYZER (FAA)) AND THREE GLUCOSE METERS: Accue Chek Advantage (AGM), BREEZE 2 (BGM), and Optimum Xceed (OGM). Ten healthy subjects were recruited for the study. The results showed OGM yield highest postprandial glucose responses of 119.6 +/- 1.5, followed by FAA, 118.4 +/- 1.2, BGM, 117.4 +/- 1.4 and AGM, 112.6 +/- 1.3 mg/dl respectively. FAA reached highest mean IAUC of 4156 +/- 208 mg x min/dl, followed by OGM (3835 +/- 270 mg x min/dl), BGM (3730 +/- 241 mg x min/dl) and AGM (3394 +/- 253 mg x min/dl). Among four methods, OGM produced highest mean GI value than FAA (87 +/- 5) than FAA, followed by BGM and AGM (77 +/- 1, 68 +/- 4 and 63 +/- 5, pOGM are more variable methods to determine IAUC, GI and rank GI value of food than FAA. The present result does not necessarily apply to other glucose meters. The performance of glucose meter to determine GI value of food should be evaluated and calibrated before use. PMID:20664730

  18. Smart meter adoption and deployment strategy for residential buildings in Indonesia

    International Nuclear Information System (INIS)

    Highlights: • Limited consumer awareness of smart meters contributes to skepticism. • Data obtained from a survey of energy users are analyzed using SEM. • A CAP index is developed via SEM results to measure consumer propensity for adopting smart meters. • The findings of this study enhance understanding of consumer perceptions and behaviors. • Concrete strategies are proposed to help policy makers and utility companies. - Abstract: For countries pursuing sustainable development and energy efficiency, the use of smart meters is considered a first step in allowing residential consumers to remotely control their energy consumption, and a promising technology for conserving limited energy resources. However, despite the growing interest in smart meters, limited consumer awareness, knowledge, and understanding of these devices contributes to skepticism. This study thus developed an index to measure consumer propensity to adopt smart meters in residential buildings. Data obtained from a survey of energy use by Indonesian households were analyzed using structural equation modeling to determine the interacting factors in consumer acceptance of smart meters. Consumer perceptions, expectations, and intentions regarding the potential use of smart meters in Indonesia were also discussed. The findings of this study enhance understanding of consumer perceptions and behaviors, and can help decision makers and energy utility companies develop policies and strategies for a “one-size-fits-all” program related to smart meter applications in future residential buildings

  19. Development of a calibration methodology and tests of kerma area product meters

    International Nuclear Information System (INIS)

    The quantity kerma area product (PKA) is important to establish reference levels in diagnostic radiology exams. This quantity can be obtained using a PKA meter. The use of such meters is essential to evaluate the radiation dose in radiological procedures and is a good indicator to make sure that the dose limit to the patient's skin doesn't exceed. Sometimes, these meters come fixed to X radiation equipment, which makes its calibration difficult. In this work, it was developed a methodology for calibration of PKA meters. The instrument used for this purpose was the Patient Dose Calibrator (PDC). It was developed to be used as a reference to check the calibration of PKA and air kerma meters that are used for dosimetry in patients and to verify the consistency and behavior of systems of automatic exposure control. Because it is a new equipment, which, in Brazil, is not yet used as reference equipment for calibration, it was also performed the quality control of this equipment with characterization tests, the calibration and an evaluation of the energy dependence. After the tests, it was proved that the PDC can be used as a reference instrument and that the calibration must be performed in situ, so that the characteristics of each X-ray equipment, where the PKA meters are used, are considered. The calibration was then performed with portable PKA meters and in an interventional radiology equipment that has a PKA meter fixed. The results were good and it was proved the need for calibration of these meters and the importance of in situ calibration with a reference meter. (author)

  20. A positioning and data logging system for surface geophysical surveys

    International Nuclear Information System (INIS)

    The Ultrasonic Ranging and Data System (USRADS) developed at ORNL is being adapted to work with two commercially available geophysical instruments: a magnetometer and an EM31 terrain conductivity meter. Geophysical surveys have proven an important preliminary step in investigating hazardous waste sites. Magnetometers and terrain conductivity meters are used to locate buried drums, trenches, conductive contaminant plumes and map regional changes in geology. About half the field time of a typical geophysical investigation is spent surveying the position of the grid points at which the measurements will be made. Additional time is lost and errors may be made recording instrument values in field notebooks and transcribing the data to a computer. Developed for gamma radiation surveys, the USRAD system keeps track of the surveyor's position automatically by triangulating on an ultrasonic transmitter carried in a backpack. The backpack also contains a radio transmitter that sends the instrument's reading coincident with the ultrasonic pulse. The surveyor's position and the instrument's reading are recorded by a portable computer which can plot the data to check the survey's progress. Electronic files are stored in a form compatible with AutoCAD to speed report writing. 7 refs., 3 figs

  1. Too cheap to meter what?

    International Nuclear Information System (INIS)

    Full text: 50 years ago, at 17:30 hours, 26 June 1954, in the town of Obninsk, near Moscow, the first nuclear power plant sent electricity to residences and businesses. Atomic energy had crossed the divide from military uses to peaceful ones, demonstrating the potential to fuel civilian electric power plants. The milestone is being marked this year at an IAEA international nuclear power conference in Obninsk. Past experience will be reviewed, but the focus is on meeting future challenges. Though it has come a long way in 50 years, nuclear energy today finds itself in a struggle of the fittest to carve a niche over the next fifty - in the marketplace and in the public eye. Cliches and sound bites tell part of the nuclear story. Visionary talk by nuclear proponents in 1954 was about future energy sources that would be 'too cheap to meter', a phrase critics pounced upon. Today in 2004 the 'too cheap to meter' phrase occasionally haunts the atom, but pops up more often than not in promotional ads for anything from wind power to web sites. Talk of nuclear energy now is of a 'renaissance' and 'second wind.' New nuclear plants are most attractive where energy demand is growing and resources are scarce, and where energy security, air pollution and greenhouse gases are priorities, IAEA Director General Mohamed ElBaradei points out. In cities, towns, and villages, reality is different, or too much the same, depending how you see and live it. Cheap or not, nuclear energy today supplies one-sixth of the world's electricity in some 30 countries. Still, it does not produce enough power. Neither does any other energy source. More than 1.5 billion people have no electricity to meter whatsoever - not from renewables, solar, nuclear, biomass, wind, coal, oil, gas, firewood, or hydrogen, the publicized promise of tomorrow. So what will it take? Maybe bigger blackouts or hotter days than the world has seen. Certainly needed are more attention, action, and money. In dollar terms

  2. Tohoku one meter bubble chamber

    International Nuclear Information System (INIS)

    At the request of Tohoku University and the National Laboratory for High Energy Physics, IHI has developed a complete freon bubble chamber system successfully, which is used for photo analysis of elementary particles physics. This system will be delivered to Fermi National Accelerator Laboratory (FNAL) in Illinois (U.S.A.) and will be coupled with the superconducting accelerator (TEVATRON) for the study of elementary particles. The total system of the freon bubble chamber is composed of a stainless steel casting spherical bubble chamber with a diameter of about one meter, an expansion system for freon pressure control, hydraulic system for driving an expansion piston, a freon feed system, a temperature control system, an overall control system as well as camera and flashlight for photograph.

    U.S Geological Survey seismologists in Menlo park, California, are utilizing the speed, reliability, and efficiency of minicomputers to monitor seismograph stations and to automatically detect earthquakes. An earthquake detection computer system, believed to be the only one of its kind in operation, automatically reports about 90 percent of all local earthquakes recorded by a network of over 100 central California seismograph stations. The system also monitors the stations for signs of malfunction or abnormal operation. Before the automatic system was put in operation, all of the earthquakes recorded had to be detected by manually searching the records, a time-consuming process. With the automatic detection system, the stations are efficiently monitored continuously. 

  5. The reactivity meter and core reactivity

    International Nuclear Information System (INIS)

    The point kinetic equations and the characteristics of the point kinetic reactivity meter are discussed, particularly for large negative reactivities. From a given input signal representing the neutron flux seen by a detector, the meter computes a value of reactivity in dollars (ρ/β), based on inverse point kinetics. The prompt jump point of view is emphasised. A simple point model of the reactor and a local flux distortion factor are used to generate input signals into a simulated reactivity meter. The obtained results show how the reading of the reactivity meter will approach the reactivity of the core model, if the reactivity is lower than -1 dollars. However, for reactivity values higher than -1 dollars, the influence of the flux distortion on the reading of the reactivity meter persists. Reactivity meter measurements taken during typical rod drop experiments in VVER-440 reactors do not produce accurate indications of the (static) core reactivity. (author)

    The transformation of water services that began with the privatisation of water companies in 1989 extended to households with the implementation of water metering. Meters 'privatised' water and the cost of provision by allocating to individual households costs that had previously been shared within the community. This (ongoing) conversion of common pool to private good has mostly improved economic, environmental and social impacts, but the potential burden of metering on poorer households has...

  9. Hardware Design of a Smart Meter

    2014-09-01

    Full Text Available Smart meters are electronic measurement devices used by utilities to communicate information for billing customers and operating their electric systems. This paper presents the hardware design of a smart meter. Sensing and circuit protection circuits are included in the design of the smart meter in which resistors are naturally a fundamental part of the electronic design. Smart meters provides a route for energy savings, real-time pricing, automated data collection and eliminating human errors due to manual readings which would ultimately reduce labour costs, diagnosis and instantaneous fault detection. This allows for predictive maintenance resulting in a more efficient and reliable distribution network.

  10. Off-level corrections for gravity meters

    Science.gov (United States)

    Niebauer, T. M.; Blitz, Thomas; Constantino, Andy

    2016-04-01

    Gravity meters must be aligned with the local gravity at any location on the surface of the earth in order to measure the full amplitude of the gravity vector. The gravitational force on the sensitive component of the gravity meter decreases by the cosine of the angle between the measurement axis and the local gravity vector. Most gravity meters incorporate two horizontal orthogonal levels to orient the gravity meter for a maximum gravity reading. In order to calculate a gravity correction it is often necessary to estimate the overall angular deviation between the gravity meter and the local gravity vector using two measured horizontal tilt meters. Typically this is done assuming that the two horizontal angles are independent and that the product of the cosines of the horizontal tilts is equivalent to the cosine of the overall deviation. These approximations, however, break down at large angles. This paper derives analytic formulae to transform angles measured by two orthogonal tilt meters into the vertical deviation of the third orthogonal axis. The equations can be used to calibrate the tilt sensors attached to the gravity meter or provide a correction for a gravity meter used in an off-of-level condition.

    We present a novel technique, automatic input rectification, and a prototype implementation, SOAP. SOAP learns a set of constraints characterizing typical inputs that an application is highly likely to process correctly. When given an atypical input that does not satisfy these constraints, SOAP automatically rectifies the input (i.e., changes the input so that it satisfies the learned constraints). The goal is to automatically convert potentially dangerous inputs into typical inputs that the ...

    The common hippopotamus (Hippopotamus amphibius L.) is part of the animal species endangered because of multiple human pressures. Monitoring of species for conservation is then essential, and the development of census protocols has to be chased. UAV technology is considering as one of the new perspectives for wildlife survey. Indeed, this technique has many advantages but its main drawback is the generation of a huge amount of data to handle. This study aims at developing an algorithm for automatic count of hippos, by exploiting thermal infrared aerial images acquired from UAV. This attempt is the first known for automatic detection of this species. Images taken at several flight heights can be used as inputs of the algorithm, ranging from 38 to 155 meters above ground level. A Graphical User Interface has been created in order to facilitate the use of the application. Three categories of animals have been defined following their position in water. The mean error of automatic counts compared with manual delineations is +2.3% and shows that the estimation is unbiased. Those results show great perspectives for the use of the algorithm in populations monitoring after some technical improvements and the elaboration of statistically robust inventories protocols.

    1991-12-01

    Much of the previous research efforts aimed at determining those physiological characteristics that contribute to distance running success have centered around distances greater than 1500 meters with little attention to events such as the 800 meter run. Therefore, this investigation examined the relationship between selected physiological and body composition, characteristics and performance in an 800 meter run. Measurements of body composition, VO2max, running economy, and performance times for 100 and 300 meter dashes were obtained on 11 male track athletes. Stepwise multiple regression analysis was performed using 800 meter race time as the dependent variable. Although the combination of 300 and 100 meter run times, percent body fat, running economy and VO2 max as independent variables accounted for the greatest amount of total variance (r2 = .89), the additional variance explained by the model did not increase significantly (p greater than 0.05), when VO2max, percent body fat, and running economy were added to a model which contained 300 and 100 meter run time (r2 = .85) as the explanatory variables. These data offer additional support for the notion that much of the intramuscular ATP produce and utilized during an 800 meter run comes from anaerobic metabolic pathway. PMID:1806725

  17. Period meter output during startup transients

    International Nuclear Information System (INIS)

    The time response of a period meter whose input signal comes from an ionization chamber may be calculated using a Ferranti Mercury digital computer programme. Details of the programme are given. The type of period meter considered is the one for which the input time constant is determined by the input capacity and the logarithmic element. The input excitation is a terminated ramp of reactivity. Other reactivity inputs may be treated. In particular the step change of reactivity may be used as the input excitation. Allowance is taken of the power dependent time constant associated with the logarithmic element and of the differentiating and integrating time constants in the period meter. The programme may be used by period meter designers to assess the performance of their instruments and may also be used by those carrying out safety and operations studies on reactors which use this type of period meter. An example of the use of the programme is given. (author)

  3. Development of a contour meter

    International Nuclear Information System (INIS)

    The dosimetric calculation in patients that receive radiotherapy treatment it requires the one knowledge of the geometry of some anatomical portions, which differs from a patient to another. Making reference to the specific case of mammary neoplasia, one of the measurements that is carried out on the patient is the acquisition of the contour of the breast, which is determined from a point marked on the breastbone until another point marked on the lateral of the thorax, below the armpit, with the patient located in the irradiation position. This measurement is carried out with the help of a mechanical contour meter that is a device conformed by a series of wires with a polymeric coating, which support on the breast of the patient and it reproduces its form. Then it is transported in the more careful possible form on a paper and the contour is traced with a tracer one. The geometric error associated to this procedure is of ±1 cm, which is sensitive of being reduced. The present work finds its motivation in the patient's radiological protection radiotherapy. The maximum error in dose allowed in radiotherapeutic treatments is 5%. It would be increase the precision and with it to optimize the treatment received by the patient, reducing the error in the acquisition process of the mammary contour. With this objective, a digital device is designed whose operation is based in the application of a spatial transformation on a picture of the mammary contour, which corrects the geometric distortion introduced in the process of the photographic acquisition. An algorithm that allows to obtain a front image (without distortion) of the plane of the contour was developed. A software tool especially developed carries out the processing of the digital images. The maximum geometric error detected in the validation process is 2 mm located on a small portion of the contour. (Author)

    The Lick-Gaertner automatic equipment has been designed mainly for the measurement of stellar proper motions with reference to galaxies, and consists of two main components: the survey machine and the automatic measuring engine. The survey machine is used for initial inspection and selection of objects for subsequent measurement. Two plates, up to 17 x 17 inches each, are surveyed simultaneously by means of projection on a screen. The approximate positions of objects selected are measured by two optical screws: helical lines cut through an aluminum coating on glass cylinders. These approximate coordinates to a precision of the order of 0.03mm are transmitted to a card punch by encoders connected with the cylinders.

  5. Preparing for smart grid technologies: A behavioral decision research approach to understanding consumer expectations about smart meters

    International Nuclear Information System (INIS)

    With the enactment of the 2009 American Recovery and Reinvestment Act, U.S. President Obama made a public commitment to a new approach to energy production and transmission in the United States. It features installing smart meters and related technologies in residential homes, as part of transforming the current electrical grid into a “smart grid.” Realizing this transformation requires consumers to accept these new technologies and take advantage of the opportunities that they create. We use methods from behavioral decision research to understand consumer beliefs about smart meters, including in-depth mental models interviews and a follow-up survey with a sample of potential smart meter customers of a major U.S. mid-Atlantic electricity utility. In both the surveys and the interviews, most respondents reported wanting smart meters. However, these preferences were often based on erroneous beliefs regarding their purpose and function. Respondents confused smart meters with in-home displays and other enabling technologies, while expecting to realize immediate savings. They also perceived risks, including less control over their electricity usage, violations of their privacy, and increased costs. We discuss the policy implications of our results. - Highlights: ► We outline normative risks and benefits of smart meters from scientific literature. ► We examine consumer perceptions of smart meters via interviews and surveys. ► Smart meter desire stems from consumer misconceptions about purpose and function. ► Appropriate communications may prevent consumer protests against the smart grid.

    This paper describes the photogrammetry method as a mean to measure the deformation of the 6-meter carbon fiber reinforced plastic (CFRP) Platform of the AMiBA interferometric array telescope installed at the Mauna Loa Observatory, Hawaii. The Platform was surveyed at a series of elevation, azimuth and polarization angles. Photogrammetry demonstrates that the deformation of the Platform is not only gravity-induced but also due to the Hexapod mount actuator. The measurement results verify the predictions of the Finite Element Analysis (FEA).

  7. Hydrogen meter for service in liquid sodium

    International Nuclear Information System (INIS)

    This standard establishes the requirements for the design, materials, fabrication, quality assurance, examination, and acceptance testing of a hydrogen meter and auxiliary equipment for use in radioactive or nonradioactive liquid sodium service. The meter shall provide a continuous and accurate indication of the hydrogen impurity concentration over the range 0.03 to 10 ppM hydrogen in sodium at temperatures between 800 and 10000F (427 and 5380C). The meter may also be used to rapidly monitor changes in hydrogen concentration, over the same concentration range, and, therefore can be used as a sensor for sodium-water reactions in LMFBR steam generators

  8. Which way through the metering maze?

    International Nuclear Information System (INIS)

    Already suffering from the unrelenting rise in electricity prices, some major energy users have found that the metering side of power purchasing offers no relief. Despite having paid out for metering equipment so that they can shop around in the second tier market for their power, those users with 1MW-plus loads have found, to their frustration, that they are unable to find out exactly what they are paying for when it comes to settling the electricity bill. Not only are they unhappy about the lack of information available, but these users are also disgruntled about the high, and unpredictable costs of metering. (author)

  9. Water metering in England and Wales

    David Zetland

    2016-02-01

    Full Text Available The transformation of water services that began with the privatisation of water companies in 1989 extended to households with the implementation of water metering. Meters 'privatised' water and the cost of provision by allocating to individual households costs that had previously been shared within the community. This (ongoing conversion of common pool to private good has mostly improved economic, environmental and social impacts, but the potential burden of metering on poorer households has slowed the transition. Stronger anti-poverty programmes would be better at addressing this poverty barrier than existing coping mechanisms reliant on subsidies from other water consumers.

    Full Text Available This paper focuses on the issues of smart metering market and considers different services provided by smart metering from consumer point of view. Firstly, smart metering deployment challenges emerging and conventional tariffs, which modify a consumer behavior and thus, the entire electric energy market can be optimized since the customer is motivated to consume less energy. Secondly, the authors illustrate changes in electricity quality, which have an impact on consumer relations with utility. Additionally, two main indices of grid resilience – SAIDI and SAIFI – are exemplified to reveal the improvement potential of smart metering implementation in certain regions of Russia that also influence the consumer. Finally, in-home display and privacy problem directly reflect the consumer’s behavior, thus the private life rights should not be violated as they are guaranteed by law.

    2010-01-01

    Full Text Available OBJECTIVE: To compare the measurements of spirometric peak expiratory flow (PEF from five different PEF meters and to determine if their values are in agreement. Inaccurate equipment may result in incorrect diagnoses of asthma and inappropriate treatments. METHODS: Sixty-eight healthy, sedentary and insufficiently active subjects, aged from 19 to 40 years, performed PEF measurements using Air Zone®, Assess®, Galemed®, Personal Best® and Vitalograph® peak flow meters. The highest value recorded for each subject for each device was compared to the corresponding spirometric values using Friedman's test with Dunn's post-hoc (p<0.05, Spearman's correlation test and Bland-Altman's agreement test. RESULTS: The median and interquartile ranges for the spirometric values and the Air Zone®, Assess®, Galemed®, Personal Best® and Vitalograph® meters were 428 (263-688 L/min, 450 (350-800 L/min, 420 (310-720 L/min, 380 (300-735 L/min, 400 (310-685 L/min and 415 (335-610 L/min, respectively. Significant differences were found when the spirometric values were compared to those recorded by the Air Zone® (p<0.001 and Galemed ® (p<0.01 meters. There was no agreement between the spirometric values and the five PEF meters. CONCLUSIONS: The results suggest that the values recorded from Galemed® meters may underestimate the actual value, which could lead to unnecessary interventions, and that Air Zone® meters overestimate spirometric values, which could obfuscate the need for intervention. These findings must be taken into account when interpreting both devices' results in younger people. These differences should also be considered when directly comparing values from different types of PEF meters.

  1. Diagnostic flow metering using ultrasound tomography

    International Nuclear Information System (INIS)

    For an accurate flow metering without considering the influences of flow control devices such as valves and elbows in closed conduits, velocity distribution in the cross-sectional area must be integrated. However, most flow meters, including multi-path ultrasonic, electromagnetic or Coriolis mass flow meters, require assumptions on the fully-developed turbulent flows to calculate flow rates from physical quantities of their own concern. Therefore, a long straight pipe has been a necessary element for accurate flow metering because the straight pipe can reduce flow disturbances caused by flow control devices. To reduce costs due to the installation of long straight pipes, another flow metering technique is required. For example, flow rates can be estimated by integrating velocity distributions in the cross section of conduits. In the present study, ultrasound tomography was used to find the velocity distribution in the cross-section of a closed conduit where flow was disturbed by a Coriolis mass flow meter or a butterfly valve. A commercial multi-path ultrasonic flow meter was installed in the pipeline to measure the line-averaged velocity distribution in the pipe flow. The ultrasonic flow meter was rotated 180 .deg. at intervals of 10 .deg. to construct line-averaged velocity distributions in Radon space. Flow images were reconstructed by using a backprojection algorithm (inverse Radon transform). Flow diagnostic parameters were defined by calculating statistical moments, i.e., average, standard deviation, skewness, and kurtosis, based on the normalized velocity distribution. The flow diagnostic parameters were applied to flow images to find whether the parameters could discern flow disturbances in the reconstructed velocity distribution

  2. Intelligent Metering for Urban Water: A Review

    Directory of Open Access Journals (Sweden)

    Rodney Stewart

    2013-07-01

    Full Text Available This paper reviews the drivers, development and global deployment of intelligent water metering in the urban context. Recognising that intelligent metering (or smart metering has the potential to revolutionise customer engagement and management of urban water by utilities, this paper provides a summary of the knowledge-base for researchers and industry practitioners to ensure that the technology fosters sustainable urban water management. To date, roll-outs of intelligent metering have been driven by the desire for increased data regarding time of use and end-use (such as use by shower, toilet, garden, etc. as well as by the ability of the technology to reduce labour costs for meter reading. Technology development in the water sector generally lags that seen in the electricity sector. In the coming decade, the deployment of intelligent water metering will transition from being predominantly “pilot or demonstration scale” with the occasional city-wide roll-out, to broader mainstream implementation. This means that issues which have hitherto received little focus must now be addressed, namely: the role of real-time data in customer engagement and demand management; data ownership, sharing and privacy; technical data management and infrastructure security, utility workforce skills; and costs and benefits of implementation.

    The Australian Dark Energy Survey (OzDES) is a 100-night spectroscopic survey underway on the Anglo-Australian Telescope using the fibre-fed 2-degree-field (2dF) spectrograph. We have developed a new redshifting application MARZ with greater usability, flexibility, and the capacity to analyse a wider range of object types than the RUNZ software package previously used for redshifting spectra from 2dF. MARZ is an open-source, client-based, Javascript web-application which provides an intuitive interface and powerful automatic matching capabilities on spectra generated from the AAOmega spectrograph to produce high quality spectroscopic redshift measurements. The software can be run interactively or via the command line, and is easily adaptable to other instruments and pipelines if conforming to the current FITS file standard is not possible. Behind the scenes, a modified version of the AUTOZ cross-correlation algorithm is used to match input spectra against a variety of stellar and galaxy templates, and automatic matching performance for OzDES spectra has increased from 54% (RUNZ) to 91% (MARZ). Spectra not matched correctly by the automatic algorithm can be easily redshifted manually by cycling automatic results, manual template comparison, or marking spectral features.

  5. SRV-automatic handling device

    International Nuclear Information System (INIS)

    Automatic handling device for the steam relief valves (SRV's) is developed in order to achieve a decrease in exposure of workers, increase in availability factor, improvement in reliability, improvement in safety of operation, and labor saving. A survey is made during a periodical inspection to examine the actual SVR handling operation. An SRV automatic handling device consists of four components: conveyor, armed conveyor, lifting machine, and control/monitoring system. The conveyor is so designed that the existing I-rail installed in the containment vessel can be used without any modification. This is employed for conveying an SRV along the rail. The armed conveyor, designed for a box rail, is used for an SRV installed away from the rail. By using the lifting machine, an SRV installed away from the I-rail is brought to a spot just below the rail so that the SRV can be transferred by the conveyor. The control/monitoring system consists of a control computer, operation panel, TV monitor and annunciator. The SRV handling device is operated by remote control from a control room. A trial equipment is constructed and performance/function testing is carried out using actual SRV's. As a result, is it shown that the SRV handling device requires only two operators to serve satisfactorily. The required time for removal and replacement of one SRV is about 10 minutes. (Nogami, K.)

    1997-07-01

    The computational fluid dynamics (CFD) work on Venturi meters reported in this paper was part of a large project for Shell Exploration and Production to investigate the application of Venturi meters to gas flow measurement. The majority of the experimental findings were reported in 'Unpredicted behaviour of Venturi flowmeters in gas at high Reynolds numbers' presented in the 1996 North Sea Flow Metering Workshop. CFD has been used to model the flow through Venturi tubes and thereby gain understanding of how the discharge coefficient is affected by the vital parameters of diameter ratio, pipe Reynolds number and roughness. It has also been used to calculate the effect of manufacturing tolerance. The discharge coefficients obtained from the calibration of Venturi meters have been used to validate the CFD predictions. The CFD results have also been compared with experimental results from the 1950s and 1960s with surprisingly good agreement. This work forms the basis of further possible research using CFD on the effect of upstream and Venturi surface roughness on the performance of these meters. The knowledge gained on the effect of surface roughness may also be applicable to ultrasonic flowmeters. (author)

    2009-10-01

    Full Text Available Abstract Background Automatic measurement of arterial blood pressure is important, but the available commercial automatic blood pressure meters, mostly based on oscillometry, are of low accuracy. Methods In this study, we present a cuff-based technique for automatic measurement of systolic blood pressure, based on photoplethysmographic signals measured simultaneously in fingers of both hands. After inflating the pressure cuff to a level above systolic blood pressure in a relatively slow rate, it is slowly deflated. The cuff pressure for which the photoplethysmographic signal reappeared during the deflation of the pressure-cuff was taken as the systolic blood pressure. The algorithm for the detection of the photoplethysmographic signal involves: (1 determination of the time-segments in which the photoplethysmographic signal distal to the cuff is expected to appear, utilizing the photoplethysmographic signal in the free hand, and (2 discrimination between random fluctuations and photoplethysmographic pattern. The detected pulses in the time-segments were identified as photoplethysmographic pulses if they met two criteria, based on the pulse waveform and on the correlation between the signal in each segment and the signal in the two neighboring segments. Results Comparison of the photoplethysmographic-based automatic technique to sphygmomanometry, the reference standard, shows that the standard deviation of their differences was 3.7 mmHg. For subjects with systolic blood pressure above 130 mmHg the standard deviation was even lower, 2.9 mmHg. These values are much lower than the 8 mmHg value imposed by AAMI standard for automatic blood pressure meters. Conclusion The photoplethysmographic-based technique for automatic measurement of systolic blood pressure, and the algorithm which was presented in this study, seems to be accurate.

    2015-11-01

    In this work, we present a digital microflow meter operating in the range 30-250 nl min-1 for water. The principle is based on determining the evaporation rate of the liquid via reading the number of wetted pore array structures in a microfluidic system, through which continuous evaporation takes place. A proof-of-principle device of the digital flow meter was designed, fabricated, and tested. The device was built on foil-based technology. In the proof-of-principle experiments, good agreement was found between set flow rates and the evaporation rates estimated from reading the number of wetted pore structures. The measurement range of the digital flow meter can be tuned and extended in a straightforward manner by changing the pore structure of the device.

  15. Flow meters for the PAT loop

    International Nuclear Information System (INIS)

    The flow of coolant in the PAT loop at temperatures in the range 2000C to 6000C and a pressure of 40 bar must be measured accurately. It is not possible to provide good upstream flow conditions for a flow meter in the complicated pipework or to calibrate a flow meter in the loop itself. Two independent combined flow conditioner and orifice meter units for subsequent insertion into the loop were designed, built and independently calibrated. The discharge coefficient was determined over the working range of Reynolds number by comparison with a standard orifice plate in the WNL high pressure gas loop. Tests at atmospheric pressure have demonstrated that, to the accuracy of measurement, the discharge coefficients of the units are unaffected by disturbances to the upstream flow. (author)

    1988-08-01

    In order to assess the performance of current meters within and near the surf zone, data from biaxial electromagnetic current meters with spherical and open frame probe geometries were intercompared. One bottom-mounted flow meter of each type was deployed in a mean depth of 7.0 m for 17 days, and two sensors of each type were deployed in a mean depth of 2.0 m for 5 days. Sensors in the shallow deployment were frequently in the surf zone. Hourly averaged mean flows measured by different sensor types are highly correlated, averaging above 0.98. The largest difference between measured mean flows is a constant bias, typically about 3.0 cm/s, which is roughly equal to the estimated accuracy of the sensor offset calibrations. Root-mean-square deviations from this constant bias are less than 2.0 cm/s, and are contributed to by errors in both gain calibration and sensor orientation. Comparisons of measured (surface gravity wave) oscillatory currents were made both between current meter types and with velocities inferred from the application of linear theory to pressure sensor data. Correlations between time series of UTrms (the rms total oscillatory velocity for a 1-hour record) were all above 0.99 in 7.0-m depth and averaged 0.95 for the shallow deployment. The average UTrms ratio (over all hour-long records) was within 1.0 ±0.07 for all current meter pairs in both deployments, which is consistent with the estimated 5% uncertainties in the flow meter gain calibration. Typical fluctuations of the UTrms ratio of any spherical and open frame sensor pair about its mean ratio, indicative of flow meter gain distortions probably associated with variations in the hydrodynamic environment, were less than 0.04 for any one deployment. Ratios of UTrms from both deployments taken together suggest that the open frame sensor overresponds, relative to the spherical probe, by about 5% at low (about 10.0 cm/s) total (mean + UTrms) speeds, and underresponds by about 5% at higher total

    2007-01-30

    Measuring the flow of liquid metal presents serious challenges. Current commercially-available flow meters use ultrasonic, electromagnetic, and other technologies to measure flow, but are inadequate for liquid metal flow measurement because of the high temperatures required by most liquid metals. As a result of the reactivity and high temperatures of most liquid metals, corrosion and leakage become very serious safety concerns. The purpose of this project is to develop a flow meter for Lockheed Martin that measures the flow rate of molten metal in a conduit.

    An impedance void meter is developed to measure the area-averaged void fraction. Its basic principle is based on the difference in the electrical conductivity between phases. Several methods of measuring void fraction are briefly reviewed and the reason why this type of void meter is chosen to develop is discussed. Basic principle of the measurement is thoroughly described and several design parameters to affect the overall function are discussed in detail. As example of applications is given for vertical air-water flow. It is shown that the current design has good dynamic response as well as very fine spatial resolution. (Author) 47 refs., 37 figs.

    Full Text Available The purpose of the study is to design a prototype model of an energy meter which has the ability of wireless data transfer such as sending emails and SMS. In the current energy monitoring scenario, manual energy meter monitoring is a cumbersome and tedious process for the electricity boards. It involves huge manpower and higher expenditure for a simple task. Manual energy meter monitoring is highly erroneous and amounts to great losses for both the consumers and the electricity boards. In this conventional technique, losing the bills and delay in the arrival of the official to note down the reading are common affairs. Complete digitalization of bill delivery and transaction processes eliminates such uneventful circumstances. The manual reading method is inefficient to meet the raising power demands. The invention described here has the potential to wipe of manual energy meter reading from the scene and replace it with a sophisticated automated system facilitating remote monitoring of energy consumption. In this proposed system, the Raspberry Pi performs all the essential functions of a microcontroller and supports features like sending emails and SMS with the aid of Wi-Fi dongle and GSM modem. This automated system enables continuous monitoring of energy consumption.

    The error test of the taximeter is divided into two aspects: (1) the test about time error of the taximeter (2) distance test about the usage error of the machine. The paper first gives the working principle of the meter and the principle of error verification device. Based on JJG517 - 2009 "Taximeter Verification Regulation ", the paper focuses on analyzing the machine error and test error of taxi meter. And the detect methods of time error and distance error are discussed as well. In the same conditions, standard uncertainty components (Class A) are evaluated, while in different conditions, standard uncertainty components (Class B) are also evaluated and measured repeatedly. By the comparison and analysis of the results, the meter accords with JJG517-2009, "Taximeter Verification Regulation ", thereby it improves the accuracy and efficiency largely. In actual situation, the meter not only makes up the lack of accuracy, but also makes sure the deal between drivers and passengers fair. Absolutely it enriches the value of the taxi as a way of transportation.

    Full Text Available This paper presents a single phase digital prepaid energy meter based on two microcontrollers and a single phase energy meter IC. This digital prepaid energy meter does not have any rotating parts. The energy consumption is calculated using the output pulses of the energy meter chip and the internal counter of microcontroller (ATmega32. A microcontroller (ATtiny13 is used as a smart card and the numbers of units recharged by the consumers are written in it. A relay system has been used which either isolates or establishes the connection between the electrical load and energy meter through the supply mains depending upon the units present in the smart card.Energy consumption (kWh, maximum demand (kW, total unit recharged (kWh and rest of the units (kWh are stored in the ATmega32 to ensure the accurate measurement even in the event of an electrical power outage that can be easily read from a 20×4 LCD. As soon as the supply is restored, energy meter restarts with the stored values. A single phase prepaid energy meter prototype has been implemented to provide measurement up to 40A load current and 230V line to neutral voltage.Necessary program for microcontrollers are written in c-language and compiled by Win-AVR libc compiler.

  10. KVP meter errors induced by plastic wrap

    International Nuclear Information System (INIS)

    The purpose of this study was to determine whether erroneous kVp meter readings, induced by plastic wrap, affected the actual kVp (output) of a dental X-ray machine. To evaluate the effect of plastic wrap on dental X-ray machine kVp meters, a radiation output device was used to measure output in mR/ma.s. An intraoral dental X-ray unit (S.S. White Model number-sign 90W) was used to make the exposures. First, the kVp meter was not covered with plastic wrap and output readings were recorded at various kVp settings with the milliamperage and time held constant. Secondly, the same kVp settings were selected before the plastic wrap was placed. Milliamperage and time were again held to the same constant. The X-ray console was then covered with plastic wrap prior to measuring the output for each kVp. The wrap possessed a static charge. This charge induced erroneous kVp meter readings. Out-put readings at the various induced kVp settings were then recorded. A kVp of 50 with no wrap present resulted in the same output as a kVp of 50 induced to read 40 or 60 kVp by the presence of wrap. Similar results were obtained at other kVp settings. This indicates that the plastic wrap influences only the kVp meter needle and not the actual kilovoltage of the X-ray machine. Dental X-ray machine operators should select kVp meter readings prior to placing plastic wrap and should not adjust initial settings if the meter is deflected later by the presence of wrap. The use of such a procedure will result in proper exposures, fewer retakes, and less patient radiation. If plastic wrap leads to consistent exposure errors, clinicians may wish to use a 0.5% sodium hypochlorite disinfectant as an alternative to the barrier technique

    2016-09-01

    This paper describes a novel methodology for burst detection in a water distribution system. The proposed method has two stages. In the first stage, a clustering algorithm was employed for outlier detection, while the second stage identified the presence of bursts. An important feature of this method is that data analysis is carried out dependent on multiple flow meters whose measurements vary simultaneously in a district metering area (DMA). Moreover, the clustering-based method can automatically cope with non-stationary conditions in historical data; namely, the method has no prior data selection process. An example application of this method has been implemented to confirm that relatively large bursts (simulated by flushing) with short duration can be detected effectively. Noticeably, the method has a low false positive rate compared with previous studies and appearance of detected abnormal water usage consists with weather changes, showing great promise in real application to multi-inlet and multi-outlet DMAs.

    Vamos¸, C˘alin

    2013-01-01

    Our book introduces a method to evaluate the accuracy of trend estimation algorithms under conditions similar to those encountered in real time series processing. This method is based on Monte Carlo experiments with artificial time series numerically generated by an original algorithm. The second part of the book contains several automatic algorithms for trend estimation and time series partitioning. The source codes of the computer programs implementing these original automatic algorithms are given in the appendix and will be freely available on the web. The book contains clear statement of the conditions and the approximations under which the algorithms work, as well as the proper interpretation of their results. We illustrate the functioning of the analyzed algorithms by processing time series from astrophysics, finance, biophysics, and paleoclimatology. The numerical experiment method extensively used in our book is already in common use in computational and statistical physics.

    Probabilistic modeling is iterative. A scientist posits a simple model, fits it to her data, refines it according to her analysis, and repeats. However, fitting complex models to large data is a bottleneck in this process. Deriving algorithms for new models can be both mathematically and computationally challenging, which makes it difficult to efficiently cycle through the steps. To this end, we develop automatic differentiation variational inference (ADVI). Using our method, the scientist on...

    1982-01-01

    This paper introduces a general procedure for automatic registration of two images which may have translational, rotational, and scaling differences. This procedure involves (1) segmentation of the images, (2) isolation of dominant objects from the images, (3) determination of corresponding objects in the two images, and (4) estimation of transformation parameters using the center of gravities of objects as control points. An example is given which uses this technique to register two images which have translational, rotational, and scaling differences.

  9. An automated locating and data logging system for geophysical surveys

    International Nuclear Information System (INIS)

    Oak Ridge National Laboratory has developed an Ultrasonic Ranging and Data System (USRADS) and interfaced the system with a Geonics EM31 terrain conductivity meter. USRADS keeps track of a surveyor's position by measuring the time-of-flight of ultrasonic pulses from an transducer carried by the surveyor in a backpack to stationary receivers arrayed over the survey area. Also built into the backpack is a radio transmitter that sends the EM31 data to a base station (van or truck) where the surveyor's position and the EM31 quadrature and inphase data are automatically recorded once a second on a portable computer. We surveyed a 13-acre landfill at Idaho National Engineering Laboratory with three people, in three days, collecting over 25,000 EM31 quadrature and inphase readings. At a normal walking pace the average distance between measurement points along the surveyor's path was about 2 ft, with an overall positioning precision of about 0.5 ft for each point. USRADS offers several advantages over conventional EM31 surveys: (1) time and money are saved because it does not require a civil survey to lay a grid before the geophysical survey begins, (2) data are directly recorded by a portable computer and are available for analysis in the field, and (3) refining or expanding the grid about an anomaly does not require civil surveying to add extra grid points. USRADS can also be used with a gamma scintillometer for radiation surveys. Currently, we are working to interface USRADS with a portable X-ray fluorescence spectrometer for detecting heavy metals in soil

  10. Effects of simulated ice on the performance of price type-AA current meter rotors

    Science.gov (United States)

    Fulford, Janice M.

    1994-01-01

    Slush ice readily adheres to the standard metal rotor of the winter Price type-AA current meter and affects the ability of the meter to measure the flow velocity accurately. Tests conducted at the U.S. Geological Survey Hydraulics Laboratory at Stennis Space Center, Mississippi, attempt to quantify the effects of slush ice on the performance of standard Price type-AA meter metal rotors. Test data obtained for rotors filled with simulated slush are compared with data for solid-cup polymer and standard hollow-cup metal rotors. Partial filling of the cups only marginally affects rotor performance at velocities greater than 15.24 centimeters per second. However, when cups are filled or over-filled with simulated slush, rotor performance is noticeably affected. Errors associated with slush over-filling and filling of cups are also significant when flows are angled vertically.

  11. Intermediate leak protection/automatic shutdown for B and W helical coil steam generator

    International Nuclear Information System (INIS)

    The report summarizes a follow-on study to the multi-tiered Intermediate Leak/Automatic Shutdown System report. It makes the automatic shutdown system specific to the Babcock and Wilcox (B and W) helical coil steam generator and to the Large Development LMFBR Plant. Threshold leak criteria specific to this steam generator design are developed, and performance predictions are presented for a multi-tier intermediate leak, automatic shutdown system applied to this unit. Preliminary performance predictions for application to the helical coil steam generator were given in the referenced report; for the most part, these predictions have been confirmed. The importance of including a cover gas hydrogen meter in this unit is demonstrated by calculation of a response time one-fifth that of an in-sodium meter at hot standby and refueling conditions

  12. Community Net Energy Metering: How Novel Policies Expand Benefits of Net Metering to Non-Generators

    Energy Technology Data Exchange (ETDEWEB)

    Rose, James; Varnado, Laurel

    2009-04-01

    As interest in community solutions to renewable energy grows, more states are beginning to develop policies that encourage properties with more than one meter to install shared renewable energy systems. State net metering policies are evolving to allow the aggregation of multiple meters on a customer’s property and to dissolve conventional geographical boundaries. This trend means net metering is expanding out of its traditional function as an enabling incentive to offset onsite customer load at a single facility. This paper analyzes community net energy metering (CNEM) as an emerging vehicle by which farmers, neighborhoods, and municipalities may more easily finance and reap the benefits of renewable energy. Specifically, it aims to compare and contrast the definition of geographical boundaries among different CNEM models and examine the benefits and limitations of each approach. As state policies begin to stretch the geographic boundaries of net metering, they allow inventive solutions to encourage renewable energy investment. This paper attempts to initiate the conversation on this emerging policy mechanism and offers recommendations for further development of these policies.

  11. Energy Theft in the Advanced Metering Infrastructure

    Science.gov (United States)

    McLaughlin, Stephen; Podkuiko, Dmitry; McDaniel, Patrick

    Global energy generation and delivery systems are transitioning to a new computerized "smart grid". One of the principle components of the smart grid is an advanced metering infrastructure (AMI). AMI replaces the analog meters with computerized systems that report usage over digital communication interfaces, e.g., phone lines. However, with this infrastructure comes new risk. In this paper, we consider adversary means of defrauding the electrical grid by manipulating AMI systems. We document the methods adversaries will use to attempt to manipulate energy usage data, and validate the viability of these attacks by performing penetration testing on commodity devices. Through these activities, we demonstrate that not only is theft still possible in AMI systems, but that current AMI devices introduce a myriad of new vectors for achieving it.

  13. SOLVENT DISPERSION AND FLOW METER CALCULATION RESULTS

    Energy Technology Data Exchange (ETDEWEB)

    Nash, C.; Fondeur, F.; Peters, T.

    2013-06-21

    Savannah River National Laboratory (SRNL) found that the dispersion numbers for the six combinations of CSSX:Next Generation Solvent (NGS) “blend” and pure NGS versus salt solution, caustic wash, and strip aqueous solutions are all good. The dispersion numbers are indications of processability with centrifugal contactors. A comparison of solvent physical and thermal properties shows that the Intek™ solvent flow meter in the plant has a reading biased high versus calibrated flow when NGS is used, versus the standard CSSX solvent. The flow meter, calibrated for CSSX solvent, is predicted to read 2.8 gpm of NGS in a case where the true flow of NGS is 2.16 gpm.

  14. On a radiochromic dye dose meter

    International Nuclear Information System (INIS)

    Radiochromic dye dose meters made of polyvinyl butyral (PVB) with hexa (hydroxyethyl) pararosaniline cyanide (HPR-CN) as the radiation-sensitive element are being developed and investigated at Risoe. This report summarizes the present results and outlines plans for further research on this dose meter. Currently the response is found to be almost stable after irradiation, but recalibration of a given batch is needed every 3-6 months because of changes in response chracteristics with age. Under typical laboratory conditions, the temperature coefficient is found to be about +1% per degree Celcius and the relative humidity coefficient +(0.4-0.5)% per percent change in relative humidity. The response drops approximately 15% when the dose rate is lowered from 1.1 Gy/sec to 0.2 Gy/sec. (author)

    Gravitational-wave detectors have been well developed and operated with high sensitivity. However, they still suffer from mirror displacement noise. In this paper, we propose a resonant speed meter, as a displacement noise-canceled configuration based on a ring-shaped synchronous recycling interferometer. The remarkable feature of this interferometer is that, at certain frequencies, gravitational-wave signals are amplified, while displacement noises are not.

  1. Is Individual Metering Socially Sustainable? The Case of Multifamily Housing in France

    Directory of Open Access Journals (Sweden)

    Bernard Barraqué

    2011-06-01

    Full Text Available Before generalising water metering and billing at the apartment level for consumer equity reasons, and alleviating the burden of water bills for poor families through increasing block tariffs (IBTs, Paris Council asked for some expert advice. The pros and cons of two separate issues – IBTs efficiency and justice; and individual household metering – were mixed. Our research first summarises various studies of the redistributive effects of tariff changes, first from flat rates to metering, and then from uniform prices to IBTs. We address the particular case of multifamily housing, where it is possible to retain collective billing, while relying on sub-metering to allocate the bill. The limitations of classical econometric surveys on large samples (in terms of understanding households’ strategies with tap water support the need for supplementary detailed sociological surveys at neighbourhood or building levels, if only to check the unexpected redistributive effects of tariff changes in practice. We review the specific French situation, peculiarly in Paris, to show that individual apartment billing is more costly and tends to have regressive effects. Like other cities in France, Paris abandoned the implementation of Art. 93 of the 2000 law, which encouraged individual billing; and we explain why.

    General formulas are derived for determining gage averaging errors of strip-type heat flux meters used in the measurement of one-dimensional heat flux distributions. The local averaging error e(x) is defined as the difference between the measured value of the heat flux and the local value which occurs at the center of the gage. In terms of e(x), a correction procedure is presented which allows a better estimate for the true value of the local heat flux. For many practical problems, it is possible to use relatively large gages to obtain acceptable heat flux measurements.

  2. A new model for the V-Cone meter in low pressure wet gas metering

    International Nuclear Information System (INIS)

    Wet gas metering with differential pressure (DP) devices (e.g. the orifice plate, the Venturi and the V-Cone) has gained increasing interest in the oil and gas industry. Many investigations have been performed and several models have been proposed. Among the DP devices, the V-Cone flow meter has received increasing attention owing to its remarkable performance characteristics, including high accuracy, excellent repeatability, wide turndowns, shorter straight length and stable signals. In this work, we developed a new method for predicting the gas flow rate in low pressure wet gas flow using a V-Cone flow meter with the diameter ratio of 0.55. The experimental fluid was air and tap water. The test pressure ranged from 0.10 to 0.48 MPa, and the gas and liquid mass flow rates ranged from 100 to 500 N m3 h−1 and from 0.030 to 0.358 m3 h−1, respectively. Thus, the Lockhart–Martinelli parameter, XLM, was up to 0.158 and the gas volume fraction ranged from 98.94% to 100%. A dimensionless parameter, K, was proposed in this work and defined as the two-phase flow coefficient of the flow meter. The results indicated that the K linearly increased with the Lockhart–Martinelli parameter. In addition, the K increased with the gas densiometric Froude number and decreased with the operating pressure when other parameters were kept constant. On the basis of the two-phase flow coefficient, a new wet gas model was developed and compared with seven popular wet gas models. It was found that with the V-Cone flow meter and under the present experimental conditions the new model produced a more accurate prediction of the wet gas than other models. The research approach to obtaining the model can also be used in the studies on other DP devices and thus will benefit the design of wet gas meters. (paper)

    While a number of publications and lectures on smart metering have already provided detailed coverage of the legal requirements, this is not the case for its implementation strategies. Coherent concepts for this task are still virtually inexistent. Any promising strategy to this end must take account of the fact that there are motives and interests involved which go far beyond the views currently prevailing in the sector. Despite the national differences, experiences gained in other European countries can offer important insights for the implementation of smart metering in Germany.

    For the past decade, the NASA Orbital Debris Program Office (ODPO) has relied on using various ground-based telescopes in Chile to acquire statistical survey data as well as photometric and spectroscopic data of orbital debris in geosynchronous Earth orbit (GEO). The statistical survey data have been used to supply the Orbital Debris Engineering Model (ORDEM) v.3.0 with debris detections in GEO to better model the environment at altitudes where radar detections are limited. The data produced for the statistical survey ranged from 30 to 40 nights per year, which only accounted for 10% of the possible observing time. Data collection was restricted by ODPO resources and weather conditions. In order to improve the statistical sampling in GEO, as well as observe and sample other orbits, NASA's ODPO with support from the Air Force Research Laboratory (AFRL), has constructed a new observatory dedicated to orbital debris - the Meter Class Autonomous Telescope (MCAT) on Ascension Island. This location provides MCAT with the unique ability to access targets orbiting at an altitude of less than 1,000 km and low inclinations (MEO), as well as highly eccentric orbits like geostationary transfer orbits. On 25 August 2015, MCAT successfully acquired scientific first light, imaging the Bug Nebula and tracked objects in LEO, MEO, and GEO. NASA is working towards characterizing the system and thoroughly testing the integrated hardware and software control to achieve fully autonomous operations by late 2016. This paper will review the history and current status of the MCAT project, the details of the telescope system, and its five currently manifested operating modes.

  9. Void fraction measurement with capacitance meter

    International Nuclear Information System (INIS)

    The void fraction in an air-water system has been measured using the capacitance meter. Various flow regimes including bubbly, slug, churn, annular and drop-annular flow have been investigated. The superficial air and water velocity have been varied in the range of 0.145 less than or equal to j /SUB f/ less than or equal to 3.62 ft/sec and 0.183 less than or equal to j /SUB g/ less than or equal to 63.7 ft/sec respectively and the void fraction has been varied from 0.04 to 0.94. The capacitance meter is calibrated by both quick closing valve method and theoretical calculation based on drift-flux model. The sensitivity of void fraction measurement on sensor shape has been investigated with sensors of different width. Using the conventional theoretical curves of void fraction vs. relative susceptance, the results show that the sensor width has strong effect on void fraction measurement especially annular flow regime. The results also show that significant discrepancy exists between the theoretical curve and the experimental results. The reason for this discrepancy has been identified due to two dimensional edge effect of the circular sensor. A 2-D model has been developed taking into account of both sensor width and flow regime which gives good prediction of the experimental results

    Full Text Available Spoken language is used by human to convey many types of information. Primarily, speech convey message via words. Owing to advanced speech technologies, people's interactions with remote machines, such as phone banking, internet browsing, and secured information retrieval by voice, is becoming popular today. Speaker verification and speaker identification are important for authentication and verification in security purpose. Speaker identification methods can be divided into text independent and text-dependent. Speaker recognition is the process of automatically recognizing speaker voice on the basis of individual information included in the input speech waves. It consists of comparing a speech signal from an unknown speaker to a set of stored data of known speakers. This process recognizes who has spoken by matching input signal with pre- stored samples. The work is focussed to improve the performance of the speaker verification under noisy conditions.

    This alkaloid automated removal machine was developed at Instrumentation Laboratory, Universiti Sultan Zainal Abidin Malaysia that purposely for removing the alkaloid toxicity from Dioscorea hispida (DH) tuber. It is a poisonous plant where scientific study has shown that its tubers contain toxic alkaloid constituents, dioscorine. The tubers can only be consumed after it poisonous is removed. In this experiment, the tubers are needed to blend as powder form before inserting into machine basket. The user is need to push the START button on machine controller for switching the water pump ON by then creating turbulence wave of water in machine tank. The water will stop automatically by triggering the outlet solenoid valve. The powders of tubers are washed for 10 minutes while 1 liter of contaminated water due toxin mixture is flowing out. At this time, the controller will automatically triggered inlet solenoid valve and the new water will flow in machine tank until achieve the desire level that which determined by ultra sonic sensor. This process will repeated for 7 h and the positive result is achieved and shows it significant according to the several parameters of biological character ofpH, temperature, dissolve oxygen, turbidity, conductivity and fish survival rate or time. From that parameter, it also shows the positive result which is near or same with control water and assuming was made that the toxin is fully removed when the pH of DH powder is near with control water. For control water, the pH is about 5.3 while water from this experiment process is 6.0 and before run the machine the pH of contaminated water is about 3.8 which are too acid. This automated machine can save time for removing toxicity from DH compared with a traditional method while less observation of the user. PMID:24783795

  13. A review of net metering mechanism for electricity renewable energy sources

    In this work, an overview of the net metering mechanism for renewable energy sources for power generation (RES-E) systems is carried out. In particular, the net metering concept is examined with its benefits and misconceptions. Furthermore, a survey of the current operational net metering schemes in different countries in the world, such as, in Europe, USA, Canada, Thailand and Australia, is carried out. The survey indicated that there are different net metering mechanisms depending on the particularities of each country (or state in the case of USA). Especially, in Europe, only five countries are using net metering in a very simple form, such as, any amount of energy produced by the eligible RES-E technology is compensated from the energy consumed by the RES-E producer, which results to either a less overall electricity bill or to an exception in payment energy taxes. In the USA and the USA territories, any customer’s net excess generation is credited to the customer’s next electricity bill for a 12-month billing cycle at various rates or via a combination between rates. The actual type of net excess generation (NEG) credit is decided by a number of set criteria, such as the type of RES-E technology, the RES-E capacity limit, the type of customer and the type of utility. Regarding any excess credit at the end of the 12-month billing cycle, this is either granted to the utilities, or carries over indefinitely to the customer’s next electricity bill, or is reconciled annually at any rate, or provides an option to the customer to choose between the last two options.

    2013-07-01

    The quantity kerma area product (PKA) is important to establish reference levels in diagnostic radiology exams. This quantity can be obtained using a PKA meter. The use of such meters is essential to evaluate the radiation dose in radiological procedures and is a good indicator to make sure that the dose limit to the patient's skin doesn't exceed. Sometimes, these meters come fixed to X radiation equipment, which makes its calibration difficult. In this work, it was developed a methodology for calibration of PKA meters. The instrument used for this purpose was the Patient Dose Calibrator (PDC). It was developed to be used as a reference to check the calibration of PKA and air kerma meters that are used for dosimetry in patients and to verify the consistency and behavior of systems of automatic exposure control. Because it is a new equipment, which, in Brazil, is not yet used as reference equipment for calibration, it was also performed the quality control of this equipment with characterization tests, the calibration and an evaluation of the energy dependence. After the tests, it was proved that the PDC can be used as a reference instrument and that the calibration must be performed in situ, so that the characteristics of each X-ray equipment, where the PKA meters are used, are considered. The calibration was then performed with portable PKA meters and in an interventional radiology equipment that has a PKA meter fixed. The results were good and it was proved the need for calibration of these meters and the importance of in situ calibration with a reference meter. (author)

    The Australian Dark Energy Survey (OzDES) is a 100-night spectroscopic survey underway on the Anglo-Australian Telescope using the fibre-fed 2-degree-field (2dF) spectrograph. We have developed a new redshifting application Marz with greater usability, flexibility, and the capacity to analyse a wider range of object types than the Runz software package previously used for redshifting spectra from 2dF. Marz is an open-source, client-based, Javascript web-application which provides an intuitive interface and powerful automatic matching capabilities on spectra generated from the AAOmega spectrograph to produce high quality spectroscopic redshift measurements. The software can be run interactively or via the command line, and is easily adaptable to other instruments and pipelines if conforming to the current FITS file standard is not possible. Behind the scenes, a modified version of the Autoz cross-correlation algorithm is used to match input spectra against a variety of stellar and galaxy templates, and automat...

  4. Two laboratory methods for the calibration of GPS speed meters

    International Nuclear Information System (INIS)

    The set-ups of two calibration systems are presented to investigate calibration methods of GPS speed meters. The GPS speed meter calibrated is a special type of high accuracy speed meter for vehicles which uses Doppler demodulation of GPS signals to calculate the measured speed of a moving target. Three experiments are performed: including simulated calibration, field-test signal replay calibration, and in-field test comparison with an optical speed meter. The experiments are conducted at specific speeds in the range of 40–180 km h−1 with the same GPS speed meter as the device under calibration. The evaluation of measurement results validates both methods for calibrating GPS speed meters. The relative deviations between the measurement results of the GPS-based high accuracy speed meter and those of the optical speed meter are analyzed, and the equivalent uncertainty of the comparison is evaluated. The comparison results justify the utilization of GPS speed meters as reference equipment if no fewer than seven satellites are available. This study contributes to the widespread use of GPS-based high accuracy speed meters as legal reference equipment in traffic speed metrology. (paper)

    1998-01-01

    Full Text Available The stratospheric ozone layer plays a crucial role in protecting living organisms against ultraviolet radiation. Chlorofluorocarbons (CFC contained in metered-dose inhalers (MDIs contribute to ozone depletion and in accordance with the Montreal Protocol on Substances That Deplete the Ozone Layer established 10 years ago, phase-out strageies have been developed worldwide for this category of agents. Alternatives to CFC-containing inhalers have been developed, such as powder inhalers and those using hydrofluoroalkanes (HFAs as propellants, which have been shown to be as safe and effective as CFC-containing inhalers and even offer interesting advantages over older inhalers. The transition to non-CFC MDIs requires a major effort to make the new products available and to ensure adequate comparision with the previous ones. It also requires a harmonization of actions taken by industry, government, licencing bodies and patients or health professional associations to ensure adequate information and education to the public and respiratory care providers.

    As part of the conceptual and preliminary design processes of the Thirty Meter Telescope (TMT), the TMT site testing team has spent the last five years measuring the atmospheric properties of five candidate mountains in North and South America with an unprecedented array of instrumentation. The site testing period was preceded by several years of analyses selecting the five candidates, Cerros Tolar, Armazones and Tolonchar in northern Chile; San Pedro Martir in Baja California, Mexico and the 13 North (13N) site on Mauna Kea, Hawaii. Site testing was concluded by the selection of two remaining sites for further consideration, Armazones and Mauna Kea 13N. It showed that all five candidates are excellent sites for an extremely large astronomical observatory and that none of the sites stands out as the obvious and only logical choice based on its combined properties. This is the first article in a series discussing the TMT site testing project.

    Handheld multi-gas meters (MGMs) are equipped with sensors to monitor oxygen (O2) levels and additional sensors to detect the presence of combustible or toxic gases in the environment. This report is limited to operational response-type MGMs that include at least four different sensors. These sensors can vary by type and by the monitored chemical. In real time, the sensors report the concentration of monitored gases in the atmosphere near the MGM. In April 2016 the System Assessment and Validation for Emergency Responders (SAVER) Program conducted an operationally-oriented assessment of MGMs. Five MGMs were assessed by emergency responders. The criteria and scenarios used in this assessment were derived from the results of a focus group of emergency responders with experience in using MGMs. The assessment addressed 16 evaluation criteria in four SAVER categories: Usability, Capability, Maintainability, and Deployability.

  9. Educational electrical appliance power meter and logger

    Science.gov (United States)

    Nunn, John

    2013-09-01

    The principles behind two different designs of inductive power meter are presented. They both make use of the microphone input of a computer which, together with a custom-written program, can record the instantaneous power of a domestic electrical appliance. The device can be built quickly and can be calibrated with reference to a known power device such as an electric kettle. Typical power-versus-time profiles are shown for a kettle, a dishwasher and a fridge-freezer. The components are cheap and the cost may be recouped many times over from the resultant energy saving. Custom software will be made available free of charge to anyone who requests it. It is hoped that students attending poorly resourced schools will be able to make power loggers for educational use.

    2013-08-01

    This paper reviews radiofrequency (RF) field levels produced by electric utility meters equipped with RF transceivers (so-called Smart Meters), focusing on meters from one manufacturer (Trilliant, Redwood City, CA, USA, and Granby, QC, Canada). The RF transmission levels are summarized based on publicly available data submitted to the U.S. Federal Communications Commission supplemented by limited independent measurements. As with other Smart Meters, this meter incorporates a low powered radiofrequency transceiver used for a neighborhood mesh network, in the present case using ZigBee-compliant physical and medium access layers, operating in the 2.45 GHz unlicensed band but with a proprietary network architecture. Simple calculations based on a free space propagation model indicate that peak RF field intensities are in the range of 10 mW m or less at a distance of more than 1-2 m from the meters. However, the duty cycle of transmission from the meters is very low (meter that were consistent with data reported by the vendor to the U.S. Federal Communications Commission. Limited measurements conducted in two houses with the meters were unable to clearly distinguish emissions from the meters from the considerable electromagnetic clutter in the same frequency range from other sources, including Wi-Fi routers and, when it was activated, a microwave oven. These preliminary measurements disclosed the difficulties that would be encountered in characterizing the RF exposures from these meters in homes in the face of background signals from other household devices in the same frequency range. An appendix provides an introduction to Smart Meter technology. The RF transmitters in wireless-equipped Smart Meters operate at similar power levels and in similar frequency ranges as many other digital communications devices in common use, and their exposure levels are very far below U.S. and international exposure limits.

  11. The dynamic response of Coriolis mass flow meters

    Cheesewright, R.; Clark, C.; Belhadj, A.; Hou, Y. Y.

    2003-09-01

    The speed of response of commercial Coriolis meters to a step change in mass flow rate corresponds to a time constant which may range from 0.1s to several seconds. This response is a result both of the dynamic response of the physical components of the meter and of the electronics and the computational algorithms used to convert that dynamic response into an estimate of the mass flow rate. A comprehensive investigation of the dynamic response is presented with a view to establishing the ultimate limits of the overall meter response. Attention is initially concentrated on a simple straight tube meter and analytical solutions are presented for the response to a step change in flow rate both for an undamped meter and for a meter with internal damping. These results are compared with results from a finite element model of the same meter and then the finite element modelling is extended to geometries typical of commercial meters. Finally, representative results are presented from an experimental study of the response of commercial meters to step changes in flow rate. A study of the essential components of the algorithm used in a meter leads to the conclusion that the time constant cannot be less than the period of one cycle of the meter drive. The analytical, finite element and experimental results all combine to show that the meters all respond in the period of one drive cycle but that the flow step induces fluctuations in the meter output which decay under the influence of the flow tube damping. It is the additional damping introduced in the signal processing to overcome these fluctuations which is responsible for the large observed time constants. Possible alternative approaches are discussed.

  12. Proceedings of the 2006 smart metering conference and expo

    International Nuclear Information System (INIS)

    Ontario's smart metering program was launched as part of a general demand response management strategy to improve energy conservation in the province. Smart metering will help consumers to control their electricity bills through conservation and demand response, and will allow consumers to better manage their energy consumption and use it more effectively during cheaper, off-peak times of day. Smart metering systems measure how much electricity a customer uses on an hourly basis, and data is transferred daily to local electricity distributors. Toronto Hydro will have close to 200,000 smart meters installed by the end of 2006. By 2010, Toronto will be North America's largest urban centre to have made the full transition to smart metering technology across its entire base. This conference provided an update of Toronto Hydro's smart metering project, as well as details of their demand response program. Presentations were given by a variety of experts in information technology as well as electric power industry leaders North American demand and response metering strategies were reviewed, as well as various initiatives in advanced metering infrastructure (AMI). Security risks associated with smart metering environments were reviewed. An evaluation of the current regulatory environment was presented along with a discussion of smart metering standards and compatibility issues. New metering technologies were presented as well as various associated demand side management tools. Smart metering pilot programs and initiatives were discussed, and best practices in smart metering were evaluated. Twenty-nine presentations were given at the conference, 13 of which have been indexed separately for inclusion in this database. refs., tabs., figs

  13. Making automatic differentiation truly automatic : coupling PETSc with ADIC

    International Nuclear Information System (INIS)

    Despite its name, automatic differentiation (AD) is often far from an automatic process. often one must specify independent and dependent variables, indicate the derivative quantities to be computed, and perhaps even provide information about the structure of the Jacobians or Hessians being computed. However, when AD is used in conjunction with a toolkit with well-defined interfaces, many of these issues do not arise. They describe recent research into coupling the ADIC automatic differentiation tool with PETSc, a toolkit for the parallel numerical solution of PDEs. This research leverages the interfaces and objects of PETSc to make the AD process very nearly transparent

    In recent years, greenhouse automatic-control, based on the measurement of solar irradiance, has been attracting attention. This control is an effective method for improving crop production. In the agricultural field, it is necessary to measure Photon Flux Density (PFD), which is an important parameter in the promotion of plant growth. In particular, the PFD of Photosynthetically Active Radiation (PAR, 400-700 nm) and Plant Biologically Active Radiation (PBAR, 300-800 nm) have been discussed in agricultural plant science. The commercial quantum meter (QM, PAR meter) can only measure Photosynthetically Photon Flux Density (PPFD) which is the integrated PFD quantity on the PAR wavelength. In this research, a band-spectral pyranometer or quantum meter using PVs with optical bandpass filters for dividing the PBAR wavelength into 100 nm bands (five independent channels) was developed. Before field testing, calibration of the instruments was carried out using a solar simulator. Next, a field test was conducted in three differing weather conditions such as clear, partly cloudy and cloudy skies. As a result, it was found that the response rate of the developed pyranometer was faster by four seconds compared with the response rate of the commercial pyranometer. Moreover, the outputs of each channel in the developed pyranometer were very similar to the integrated outputs of the commercial spectroradiometer. It was confirmed that the solar irradiance could be measured in each band separately using the developed band-spectral pyranometer. It was indicated that the developed band-spectral pyranometer could also be used as a PV band-spectral quantum meter which is obtained by converting the band irradiance into band PFD.

The commercial quantum meter (QM, PAR meter) can only measure Photosynthetically Photon Flux Density (PPFD) which is the integrated PFD quantity on the PAR wavelength. In this research, a band-spectral pyranometer or quantum meter using PVs with optical bandpass filters for dividing the PBAR wavelength into 100 nm bands (five independent channels) was developed. Before field testing, calibration of the instruments was carried out using a solar simulator. Next, a field test was conducted in three differing weather conditions such as clear, partly cloudy and cloudy skies. As a result, it was found that the response rate of the developed pyranometer was faster by four seconds compared with the response rate of the commercial pyranometer. Moreover, the outputs of each channel in the developed pyranometer were very similar to the integrated outputs of the commercial spectroradiometer. It was confirmed that the solar irradiance could be measured in each band separately using the developed band-spectral pyranometer. It was indicated that the developed band-spectral pyranometer could also be used as a PV band-spectral quantum meter which is obtained by converting the band irradiance into band PFD.

  16. Development of simple band-spectral pyranometer and quantum meter using photovoltaic cells and bandpass filters

    International Nuclear Information System (INIS)

    In recent years, greenhouse automatic-control, based on the measurement of solar irradiance, has been attracting attention. This control is an effective method for improving crop production. In the agricultural field, it is necessary to measure Photon Flux Density (PFD), which is an important parameter in the promotion of plant growth. In particular, the PFD of Photosynthetically Active Radiation (PAR, 400-700 nm) and Plant Biologically Active Radiation (PBAR, 300-800 nm) have been discussed in agricultural plant science. The commercial quantum meter (QM, PAR meter) can only measure Photosynthetically Photon Flux Density (PPFD) which is the integrated PFD quantity on the PAR wavelength. In this research, a band-spectral pyranometer or quantum meter using PVs with optical bandpass filters for dividing the PBAR wavelength into 100 nm bands (five independent channels) was developed.

    Full Text Available Automatic dialect identification is a necessary Lan guage Technology for processing multi- dialect languages in which the dialects are linguis tically far from each other. Particularly, this becomes crucial where the dialects are mutually uni ntelligible. Therefore, to perform computational activities on these languages, the sy stem needs to identify the dialect that is the subject of the process. Kurdish language encompasse s various dialects. It is written using several different scripts. The language lacks of a standard orthography. This situation makes the Kurdish dialectal identification more interesti ng and required, both form the research and from the application perspectives. In this research , we have applied a classification method, based on supervised machine learning, to identify t he dialects of the Kurdish texts. The research has focused on two widely spoken and most dominant Kurdish dialects, namely, Kurmanji and Sorani. The approach could be applied to the other Kurdish dialects as well. The method is also applicable to the languages which are similar to Ku rdish in their dialectal diversity and differences.

  3. De Minimis Thresholds for Federal Building Metering Appropriateness

    Henderson, Jordan W. [Pacific Northwest National Lab. (PNNL), Richland, WA (United States)

    2015-03-31

    The U.S. Department of Energy (DOE) is required by statute and Presidential Memorandum to establish guidelines for agencies to meter their Federal buildings for energy (electricity, natural gas, and steam) and water. See 42 U.S.C. § 8253(e). DOE issued guidance in February 2006 on the installation of electric meters in Federal buildings. A recent update to the 2006 guidance accounts for more current metering practices within the Federal Government. The updated metering guidance specifies that all Federal buildings shall be considered “appropriate” for energy or water metering unless identified for potential exclusion. In developing the updated guidance to carry out the statue, Congress also directed DOE to (among other things) establish exclusions from the metering requirements based on the de minimis quantity of energy use of a Federal building, industrial process, or structure. This paper discusses the method used to identify de minimis values.

  5. Economic and social impacts of converting to tenant metering in multi-family housing

    International Nuclear Information System (INIS)

    A current trend in the multifamily housing industry is to convert heating (gas and oil) systems to tenant-metered heating systems (electric zonal heat, individual gas furnaces, secondary metering systems for boilers). Moving responsibility for heating costs directly to tenants has been shown to save energy (on the order of 15%). However, there are social and economic aspects of this type of 'energy investment' such as the impact on vacancy rates, rent levels and comfort of tenants. This paper presents the findings from a research project that surveyed the owners and tenants of 37 multifamily buildings (a total of 741 units) that had been converted from central to individual metering. In addition to the behavioral analysis, the authors gathered utility billing data which they analyzed using the Princeton Scorekeeping Method. Survey findings indicate that energy use was decreased substantially by conversion to separate heating systems. Increases in tenant-paid utility bills after conversion were not sufficient to cause hardship for most tenants, even those with modest incomes. Rent and vacancy levels remained stable after the heating system changes were made or an allocation system was installed

    The same technology and analytic approaches that led to cost-effective unmitigated successes for the spaceborne Kepler and WISE telescopes are now being applied to meter-class to 4-meter-class ground telescopes, providing affordable solutions to ground astronomy, with advanced features as needed for the application. The range of optical and mechanical performance standards and features that can be supplied for ground astronomy shall be described. Both classical RC designs, as well as unobscured designs are well represented in the IOS design library, allowing heritage designs for both night time and day time operations, the latter even in the proximity of the sun. In addition to discussing this library of mature features, we will also describe a process for working with astronomers early in the definition process to provide the best-value solution. Solutions can include remote operation and astronomical data acquisition and transmission.

  11. Clothes Dryer Automatic Termination Evaluation

    TeGrotenhuis, Ward E.

    2014-10-01

    Volume 2: Improved Sensor and Control Designs Many residential clothes dryers on the market today provide automatic cycles that are intended to stop when the clothes are dry, as determined by the final remaining moisture content (RMC). However, testing of automatic termination cycles has shown that many dryers are susceptible to over-drying of loads, leading to excess energy consumption. In particular, tests performed using the DOE Test Procedure in Appendix D2 of 10 CFR 430 subpart B have shown that as much as 62% of the energy used in a cycle may be from over-drying. Volume 1 of this report shows an average of 20% excess energy from over-drying when running automatic cycles with various load compositions and dryer settings. Consequently, improving automatic termination sensors and algorithms has the potential for substantial energy savings in the U.S.

    Research by Raz and his associates has repeatedly found that suggestions for hypnotic agnosia, administered to highly hypnotizable subjects, reduce or even eliminate Stroop interference. The present paper sought unsuccessfully to extend these findings to negative priming in the Stroop task. Nevertheless, the reduction of Stroop interference has broad theoretical implications, both for our understanding of automaticity and for the prospect of de-automatizing cognition in meditation and other altered states of consciousness.

    The continued growth of the obesity epidemic at a time when obesity is highly stigmatizing should make us question the assumption that, given the right information and motivation, people can successfully reduce their food intake over the long term. An alternative view is that eating is an automatic behavior over which the environment has more control than do individuals. Automatic behaviors are those that occur without awareness, are initiated without intention, tend to continue without contr...

    Full Text Available The calibration of pH meters including the pH glass electrode, ISE electrodes,buffers, and the general background for calibration are reviewed. Understanding of basicconcepts of pH, pOH, and electrode mechanism is emphasized. New concepts of pH, pOH,as well as critical examination of activity, and activity coefficients are given. Theemergence of new solid state pH electrodes and replacement of the salt bridge with aconducting wire have opened up a new horizon for pH measurements. A pH buffer solutionwith a conducting wire may be used as a stable reference electrode. The misleadingunlimited linear Nernstian slope should be discarded. Calibration curves with 3 nonlinearportions for the entire 0—14 pH range due to the isoelectric point change effect areexplained. The potential measurement with stirring or unstirring and effects by double layer(DL and triple layer (TL will be discussed.

  17. Evaluation of MDA instant working level meters

    International Nuclear Information System (INIS)

    The U.S. Bureau of Mines and the Mine Safety and Health Administration have evaluated, for accuracy and reliability, a commercially available Instant Working Level Meter (IWLM) used by the mining industry to measure short-lived 222Rn-progeny concentrations. Six evaluation parameters were determined experimentally. These included two alpha and two beta detector efficiencies for the short-lived 222Rn progeny and two internal conversion factors. The experimental procedure detailing the evaluation technique is described in the paper. The measuring accuracy of 13 instruments is as follows: average inherent uncertainty (at least 68% confidence interval) is +/- 18%; for counting statistics and rounding at 0.10 WL (2.1 microJ m-3), coefficients of variation range from +/- 15% at low gamma flux backgrounds to +/- 50% at gamma flux backgrounds of 0.39 microC kg-1 h-1 (1.5 mR h-1). All parameters were derived theoretically and measured experimentally. All tests were conducted at a sample flow rate of 2.5 L min-1. A sample air flow rate of 7.5 L min-1 can lower the counting statistics to more acceptable levels at 0.1 WL (2.1 microJ m-3)

    The TMT Detailed Science Case describes the transformational science that the Thirty Meter Telescope will enable. Planned to begin science operations in 2024, TMT will open up opportunities for revolutionary discoveries in essentially every field of astronomy, astrophysics and cosmology, seeing much fainter objects much more clearly than existing telescopes. Per this capability, TMT's science agenda fills all of space and time, from nearby comets and asteroids, to exoplanets, to the most distant galaxies, and all the way back to the very first sources of light in the universe. More than 150 astronomers from within the TMT partnership and beyond offered input in compiling the new 2015 Detailed Science Case. The contributing astronomers represent the entire TMT partnership, including the California Institute of Technology (Caltech), the Indian Institute of Astrophysics (IIA), the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), the National Astronomical Observatory of Japan (NAOJ), the University of California, the Association of Canadian Universities for Research in Astronomy (ACURA) and US associate partner, the Association of Universities for Research in Astronomy (AURA).

  19. Thirty meter telescope observatory software architecture

    International Nuclear Information System (INIS)

    The Thirty Meter Telescope (TMT) will be a ground-based, 30-m optical-IR telescope with a highly segmented primary mirror located on the summit of Mauna Kea in Hawaii. The TMT Observatory Software (OSW) system will deliver the software applications and infrastructure necessary to integrate all TMT software into a single system and implement a minimal end-to-end science operations system. At the telescope, OSW is focused on the task of integrating and efficiently controlling and coordinating the telescope, adaptive optics, science instruments, and their subsystems during observation execution. From the software architecture viewpoint, the software system is viewed as a set of software components distributed across many machines that are integrated using a shared software base and a set of services that provide communications and other needed functionality. This paper describes the current state of the TMT Observatory Software focusing on its unique requirements, architecture, and the use of middle-ware technologies and solutions that enable the OSW design.

  20. Thirty meter telescope adaptive optics computing challenges

    International Nuclear Information System (INIS)

    The Thirty Meter Telescope (TMT) will be used with Adaptive Optics (AO) systems to allow near diffraction-limited performance in the near-infrared and achieve the main TMT science goals. Adaptive optics systems reduce the effect of the atmospheric distortions by dynamically measuring the distortions with wavefront sensors, performing wavefront reconstruction with a real time controller (RTC), and then compensating for the distortions with deformable mirrors. The requirements for the RTC subsystem of the TMT first light AO system will represent a significant advance over the current generation of astronomical AO control systems. Memory and processing requirements would be at least 2 orders of magnitude greater than the currently most powerful AO systems using conventional approaches, so that innovative wavefront reconstruction algorithms and new hardware approaches will be required. In this paper, we will first present the requirements and challenges for the RTC of the first light AO system, together with the algorithms that have been developed to reduce the memory and processing requirements, and then two possible hardware architectures based on Field Programmable Gate Array (FPGA).
