Cathodic protection of concrete structures: A case study of Madeira airport [PDF]

open access: yesMATEC Web of Conferences
Reinforced concrete structures located near the coast are particularly prone to corrosion due to the presence of chloride ions in the air surrounding the structures.

Improved Dimension-Reduced Structures of 3D-STAP on Nonstationary Clutter Suppression for Space-Based Early Warning Radar

open access: yesRemote Sensing, 2022
By introducing degrees of freedom (DOFs) in elevation, the elevation-azimuth-Doppler three-dimensional space–time adaptive processing (3D-STAP) methods have better performance when suppressing the nonstationary clutter caused by the Earth’s rotation in ...

Knowledge-aided STAP in heterogeneous clutter using a hierarchical bayesian algorithm [PDF]

open access: yes, 2011
This paper addresses the problem of estimating the covariance matrix of a primary vector from heterogeneous samples and some prior knowledge, under the framework of knowledge-aided space-time adaptive processing (KA-STAP).

STAP [PDF]

open access: yes, 2013
The comparative analysis of ss-rRNA sequences is one of the most powerful approaches for studying phylogenetic relationships among all organisms. Our ss-rRNA Taxonomy Assigning Pipeline (STAP) combines publicly available packages such as, PHYML, BLASTN ...

Training sample selection for space–time adaptive processing based on multi-frames

open access: yesThe Journal of Engineering, 2019
As training samples are not identically distributed with cell under test (CUT) in heterogeneous environments, the performance of space–time adaptive processing (STAP) to suppress clutter degrades. To improve the performance of STAP, this study proposes a

Knowledge‐aided block sparse Bayesian learning STAP for phased‐array MIMO airborne radar

open access: yesIET Radar, Sonar & Navigation, 2021
The phased‐array multiple‐input multiple‐output (PA‐MIMO) airborne radar faces more severe sample shortage problem than the conventional PA radar. Hence, it suffers from severe performance degradation when it adopts the traditional space‐time adaptive ...

Joint allocation of transmit-receive resource for MIMO-STAP [PDF]

open access: yes, 2023
Aiming to address the issue of target detection performance degradation due to limited resources of airborne multiple-in multiple-out (MIMO) radar, a joint allocation method of transmit-receive spatial-temporal resources is developed to ameliorate the ...

Polarisation-space-time adaptive processing for heterogeneous clutter suppression of airborne-phased array radar

open access: yesThe Journal of Engineering, 2019
Conventional space-time adaptive processing (STAP) achieves clutter suppression by combining spatial signals and the temporal pulses. However, extreme slow-moving target cannot be effectively detected by space-time joint filtering in ambiguous and non ...

Expression of signal-transducing adaptor protein-1 attenuates experimental autoimmune hepatitis via down-regulating activation and homeostasis of invariant natural killer T cells.

open access: yesPLoS ONE, 2020
ObjectiveSignal-transducing adaptor protein (STAP) family members function as adaptor molecules and are involved in several events during immune responses. Notably however, the biological functions of STAP-1 in other cells are not known.
