Rainfall prediction for data-scarce areas using meteorological satellites in the case of the lake Tana sub-basin, Ethiopia

Journal of Water and Climate Change
In African nations with complex topographies, alternative rainfall estimation methods such as satellites are crucial. This study aimed at predicting the spatial and temporal distribution of rainfall in the lake Tana sub-basin from 1990 to 2020.

Impact of Decoherence on Internal State Cooling using Optical Frequency Combs

, 2012
We discuss femtosecond Raman type techniques to control molecular vibrations, which can be implemented for internal state cooling from Feshbach states with the use of optical frequency combs with and without modulation.

Analysis of CHIRPS and GPM-IMERG and Discharge Modeling with Transfer Function-GRU in Gembong Watershed, Pasuruan

Jurnal Teknik Pengairan
Rain gauges in Indonesia are often unevenly distributed, with significant gaps in data availability. As an alternative, satellite precipitation products (SPPE), such as CHIRPS and GPM-IMERG, are increasingly used for precipitation estimates. Additionally,

Clumps of material orbiting a black hole and the QPOs

, 2008
Clumps of material orbiting a black hole may be disturbed, somewhat like comets in the Kuiper belt, to relatively small periastron orbits. Each periastron passage changes the orbital parameters in such a way that the orbit becomes more and more eccentric

Vocal Classification of Vocalizations of a Pair of Asian Small-Clawed Otters to Determine Stress [PDF]

, 2015
Asian Small-Clawed Otters (Aonyx cinerea) are a small, protected but threatened species living in freshwater. They are gregarious and live in monogamous pairs for their lifetimes, communicating via scent and acoustic vocalizations.

Orthogonal Chirp Division Multiplexing

, 2016
Chirp waveform plays a significant role in radar and communication systems for its ability of pulse compression and spread spectrum. This paper presents a principle of orthogonally multiplexing a bank of linear chirp waveforms within the same bandwidth ...
