AP19-OLR Challenge: Three Tasks and Their Baselines [PDF]
2019 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC), 2019 This paper introduces the fourth oriental language recognition (OLR) challenge AP19-OLR, including the data profile, the tasks and the evaluation principles. The OLR challenge has been held successfully for three consecutive years, along with APSIPA Annual Summit and Conference (APSIPA ASC).

OLR-filtenna for Wi-Fi applications
2016 Progress in Electromagnetic Research Symposium (PIERS), 2016Microstrip open loop resonators with annular or square configuration are widely used in the design of filters and antennas. In this paper a new compact microstrip OLR based filters are designed and analyzed. This filter configuration is extended to work as a filter antenna.

Variation Characteristics of OLR for the Wenchuan Earthquake
Chinese Journal of Geophysics, 2010AbstractBased on the outgoing long‐wave radiation data of geostationary satellite and their variation characteristics, this paper proposes a method for extracting earthquake thermal infrared anomaly, namely, the relative variance rate of power spectrum estimation.

Spectrally resolved OLR from IASI measurements
2020<p>The Earth&#8217;s Outgoing Longwave Radiation (OLR) is a key component in the study of climate feedbacks and processes. As part of the Earth&#8217;s radiation budget, it reflects how the Earth-atmosphere system compensates the incoming solar radiation at the top of the atmosphere.

Relationship of Stress Changes and Anomalies in OLR Data of the Wenchuan and Lushan Earthquakes
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2018 The Longmenshan fault zone in southwest China has produced two large earthquakes within the last few years: the Wenchuan earthquake with magnitude scale (Ms) 8.0 on May 12, 2008, and the Lushan earthquake with Ms 7.0 on April 20, 2013. In this paper, we investigate the Coulomb stress changes, the data from the strainmeters and pendulum tiltmeter which ...

Study on the effect of feeding mechanism in the frequency response of OLR
2018 2nd International Conference on Inventive Systems and Control (ICISC), 2018Planar resonator structures play a vital role in wireless communication systems. The characteristics of resonators depend upon its structure and its feeding mechanism. Each variation in the geometric structure and the feeding mechanism leads to the change in the characteristics of the entire system. In this paper, there is a detailed analysis of planar

A Comparison of OLR and Circulation-Based Indices for Tracking the MJO
Monthly Weather Review, 2014Abstract Two univariate indices of the Madden–Julian oscillation (MJO) based on outgoing longwave radiation (OLR) are developed to track the convective component of the MJO while taking into account the seasonal cycle. These are compared with the all-season Real-time Multivariate MJO (RMM) index of Wheeler and Hendon derived from a ...

Characterizing Warm-ENSO Variability in the Equatorial Pacific: An OLR Perspective*,+
Journal of Climate, 2010Abstract It is shown that space–time smoothed outgoing longwave radiation (OLR) indices of equatorial Pacific seasonal variability can give an interestingly different perspective on El Niño than is obtained from sea surface temperature (SST) indices or the Southern Oscillation index (SOI).
