Oscillation modes of humidity over the Amazon basin derived from GPS RO profiles [PDF]

open access: yes, 2013
The Global Positioning System radio occultation (GPS RO) technique provides vertical profiles of refractivity from which water vapor can be derived. It is possible to reproduce global, synoptic, and regional climatological patterns.

Radiative decays of light vector mesons in a quark level linear sigma model [PDF]

open access: yes, 2002
We calculate the P0 to gamma gamma, V0 to P0 gamma and V0to V'0 gamma gamma decays in the framework of a U(3)xU(3) linear sigma model which includes constituent quarks.

Research on the Fault Diagnosis Method for Rolling Bearings Based on Improved VMD and Automatic IMF Acquisition

open access: yesShock and Vibration, Volume 2020, Issue 1, 2020., 2020
This paper proposes a novel method to improve the variational mode decomposition (VMD) method and to automatically acquire the sensitive intrinsic mode function (IMF). First, since fault signals are impulsive and periodic, a weighted autocorrelative function maximum (AFM) indicator is constructed based on the Gini index and autocorrelation function to ...

Recent advances in osmotic energy generation via pressure-retarded osmosis (PRO): A review [PDF]

open access: yes, 2015
© 2015 by the authors. Global energy consumption has been highly dependent on fossil fuels which cause severe climate change and, therefore, the exploration of new technologies to produce effective renewable energy plays an important role in the world ...

variED : an editor for collaborative, real-time feature modeling [PDF]

open access: yes, 2021
Feature models are a helpful means to document, manage, maintain, and configure the variability of a software system, and thus are a core artifact in software product-line engineering.

A Session‐Based Song Recommendation Approach Involving User Characterization along the Play Power‐Law Distribution

open access: yesComplexity, Volume 2020, Issue 1, 2020., 2020
In recent years, streaming music platforms have become very popular mainly due to the huge number of songs these systems make available to users. This enormous availability means that recommendation mechanisms that help users to select the music they like need to be incorporated.

Sub-Bottom Sediment Classification Using Reliable Instantaneous Frequency Calculation and Relaxation Time Estimation

open access: yesRemote Sensing, 2021
The shift in IF (instantaneous frequency) series and the corresponding relaxation time have the potential to characterize sediment properties. However, these attributes derived from SBP (sub-bottom profiler) data are seldom used for offshore site ...

Model Independent Electromagnetic corrections in hadronic $\tau$ decays [PDF]

open access: yes, 2013
The long distance correction to the total decay width of the $\tau^{\pm}\to K^{0}\pi^{\pm}\nu$ decay is calculated in a model independent approach where a discrimination of photons in the Bremmstrahlung process is assumed.
