In this paper we present results from the METER (MEasuring TExt Reuse) project whose aim is to explore issues pertaining to text reuse and derivation, especially in the context of newspapers using newswire sources. Although the reuse of text by journalists has been studied in linguistics, we are not aware of any investigation using existing computational methods for this particular task. We inv...

This paper introduces a novel way to detect metrical structure in music. We introduce a way to compute autocorrelation such that the distribution of energy in phase space is preserved in a matrix. The resulting autocorrelation phase matrix is useful for several tasks involving metrical structure. First we can use the matrix to enhance standard autocorrelation by calculating the Shannon entropy ...

A microcontroller based capacitance meter using 89C52 microcontroller for the measurement of capacitance has been design and developed. It is based on the principle of charging and discharging of the capacitor. Atmel’s AT89C52 microcontroller is used in the present study. Further, an LCD module is interfaced with the microcontroller in 4-bit mode, which reduces the hardware complexity. Software...

The widespread deployment of smart meters for electricity gas and water consumption to modernise the electricity systems, has been associated with privacy concerns. In this paper, we present protocols that can be used to privately compute aggregate meter measurements, allowing for fraud and leakage detection as well as further statistical processing of meter measurements, without revealing any ...

This paper outlines the operating principles and application of ultrasonic gas flow metering for custody transfer. Basic principles and underlying equations are discussed, as are considerations for applying ultrasonic flow meter technology to station design, installation, and operation. These applications are illustrated based on operating experience with the SICK ultrasonic flow meter, however...

An inexpensive yet portable device for calibrating four different flow meters in the undergraduate fluid mechanics laboratory was designed and constructed. The apparatus contains a rotameter, a turbine-type meter, a venturi meter, and an orifice meter. All four meters are calibrated simultaneously using a volumetric measuring tank. Results obtained by undergraduate students are presented, and a...

unaccounted-for-water is a misleading term long used by water industry. unaccounted-for-water includes unmeasured volume of water that run out of access from supply to end consumer and consequently leads no revenue for supplier. examples of water losses are: meter inaccuracies, illegal connection and unauthorized usage of water, abnormal meter reading, reservoir seepage and leakage, reservoir o...

The United States Federal Communications Commission delivered to Congress a national broadband plan in 2010. The purpose of this article is to analyze key economic arguments involving the development of the broadband plan addressing open network and competition issues, to make recommendations to the Commission in its formulation of federal policy as to positions that make the most economic sens...
