This paper presents an automatic meter extraction system which relies on auto-correlation coefficients. The input format for music is midi, and we assume that a beat is known. As output, our algorithm provides a set of possible metric groupments sorted by a confidence criteria. The algorithm has been tested on several pieces of Rameau and results are encouraging.

Smart electricity meters have been replacing conventional meters worldwide, enabling automated collection of fine-grained (every 15 minutes or hourly) consumption data. A variety of smart meter analytics algorithms and applications have been proposed, mainly in the smart grid literature, but the focus thus far has been on what can be done with the data rather than how to do it efficiently. In t...

This report describes the development of a low cost, digital Micro Electro Mechanical System (MEMS) vibration meter that reports an approximation to the RMS acceleration of the vibration to which the vibration meter is subjected. The major mechanical element of this vibration meter is a cantilever beam, which is on the order of 500 µm in length, with a piezoresistor deposited at its base. Vibra...

AIM to study the role of'Xerosis Meter' in screening of dry eye cases in a large population and compare its results with Schirmer's test and tear break-up time. MATERIALS AND METHOD in a cross sectional study with a control group dry eye was evaluated with Xerosis Meter, Schirmer test and tear film break-up time (TBUT). Cases included in the study were divided into two groups. Group I (Contro...

BACKGROUND Gait characteristics measured at usual pace may allow profiling in patients with cognitive problems. The influence of age, gender, leg length, modified speed or dual tasking is unclear. METHODS Cross-sectional analysis was performed on a data registry containing demographic, physical and spatial-temporal gait parameters recorded in five walking conditions with a GAITRite® electroni...

In this paper the use of a Hybrid Wireless Mesh Network (HWMN) technologies for the smart grid of Advanced Metering Infrastructure (AMI), which enables the collecting of meter data in real-time, was proposed and analyzed. A Google Maps mashup was developed to read the real GIS data from a local utility company and display the locations of the meters and light poles, which can be selected for mo...

Electromagnetic flow meters based on the principles of Faraday’s laws of induction have been used successfully in many industries. The conventional electromagnetic flow meter can measure the mean liquid velocity in axisymmetric single phase flows. However, in order to achieve velocity profile measurements in single phase flows with non-uniform velocity profiles, a novel Imaging Electromagnetic ...

This paper presents an auto-recognition method for pointer-type meter based on computer vision. Two calibrated cameras are located in the right and left sides of the meter to capture the meter displayed images. In each displayed image, the fast Hough transform method is used to locate the approximate pointer area and then the least squares fitting method is used to determine the precise line th...

In this paper, we describe the development of smart meter using Advanced Metering Infrastructure (AMI). This entails transport of metering data from energy consumer’s premises to the data management systems of energy provider using a practical mesh networking solution to realize metering communication. When the demand in the grid increases with decreased amount of power generated, this in turn ...
