Efficacy studies on ECO₂FUME® phosphine fumigant for complete control of Sitophilus zeamais and Tribolium castaneum in stored maize in Thailand

open access: yesJulius-Kühn-Archiv, 2018
ECO₂FUME® fumigation of maize bag stacks under gas proof sheets was conducted to establish the optimal dosages (application rate) and exposure times (fumigation period) against mixed-age cultures of Sitophilus zeamais and Tribolium castaneum.

Pelibatan Tuhan dalam Wacana Larangan Membuang Sampah: Antara Doa dan Sumpah Serapah

open access: yesAl-Adabiya: Jurnal Kebudayaan dan Keagamaan, 2021
One of the main community problems related to rubbish is disposing of it carelessly. This fact then gave rise to various responses such as placing the no-littering signs conveyed through prayer and swearing.

Application of ECO2FUME® phosphine fumigant for the complete control of major stored product insect pests in milled rice in Thailand

open access: yesJulius-Kühn-Archiv, 2018
ECO2FUME® phosphine fumigant was used to fumigate milled rice in a commercial plastic bag (5 kg) and milled rice in a jumbo bag (1,000 kg) under gas-proof sheets to assess its performance against a mixed-age culture of Sitophilus zeamais, Tribolium ...

Gridless DOA Estimation and Root-MUSIC for Non-Uniform Linear Arrays [PDF]

open access: yesIEEE Transactions on Signal Processing, 2020
Gridless direction of arrival (DOA) estimation is addressed for a 1-D non-uniform array (NUA) of arbitrary geometry. Currently, gridless DOA estimation is solved via convex relaxation, and is applicable only to uniform linear arrays (ULA). The ULA sample

The influence of random element displacement on DOA estimates obtained with (Khatri-Rao-)root-MUSIC [PDF]

open access: yes, 2014
Although a wide range of direction of arrival (DOA) estimation algorithms has been described for a diverse range of array configurations, no specific stochastic analysis framework has been established to assess the probability density function of the ...

Stochastic framework for evaluating the effect of displaced antenna elements on DOA estimation [PDF]

open access: yes, 2017
We establish a statistical framework for investigating the influence of correlated random displacements of antenna elements in a uniform circular antenna array (UCA) on the distribution of direction-of-arrival (DOA) estimates. More specifically, we apply

DOA Estimation in B5G/6G: Trends and Challenges

open access: yesItalian National Conference on Sensors, 2022
Direction-of-arrival (DOA) estimation is the preliminary stage of communication, localization, and sensing. Hence, it is a canonical task for next-generation wireless communications, namely beyond 5G (B5G) or 6G communication networks.

Low-Cost Beamforming and DOA Estimation Based on One-Bit Reconfigurable Intelligent Surface [PDF]

open access: yesIEEE Signal Processing Letters, 2022
In this work, we consider the Direction-of-Arrival (DOA) estimation problem in a low-cost architecture where only one antenna as the receiver is aided by a reconfigurable intelligent surface (RIS).
