The global mean of aerosol optical depth at 550 nm over land is ~0.19 and over oceans is ~0.13. About 45% of the Earth surface shows AOD at 550 nm smaller than 0.1. Hence, there is a need for measurement techniques that are optimized to measure aerosol optical properties under low AOD conditions. Over the past decade the multi-axis differential optical

DOA Estimation in heteroscedastic noise
Signal Processing, 2019The paper considers direction of arrival (DOA) estimation from long-term observations in a very noisy environment. The concern is to derive methods obtaining reasonable DOAs at very low SNR. The noise is assumed zero-mean Gaussian and its variance varies in time and space, causing stationary data models to fit poorly over long observation times ...

Practical DOA Estimation via a Network of DOA-Blind Sensors
2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007We consider the problem of DOA (direction of arrival) estimation of an acoustic wavefront by a wireless sensor network (WSN) within the SENMA architecture (a mobile agent (MA) repeatedly polls the sensors lying inside its field of view). The sensors, which are random in number and location, are DOA-blind and simply emit a pulse train synchronized to ...

Doa dalam Al-Qur’an: Studi terhadap Doa-Doa Para Nabi
Ikhlas : Jurnal Ilmiah Pendidikan IslamPrayer constitutes the essence of worship in Islam and serves as a profound expression of faith, resilience, and spiritual submission. This study aims to unveil the multifaceted dimensions of the prophets’ prayers in the Qur’an by integrating the adābi ijtimāʾī approach of Tafsir Al-Azhar (Buya Hamka) and the lughāwī approach of Tafsir al-Kashshāf ...
