Low Computational Burden Adaptive Overcurrent Protection for Active Distribution Networks
International Transactions on Electrical Energy Systems, Volume 2023, Issue 1, 2023., 2023 Conventional distribution networks have evolved into active distribution networks due to the high penetration of distributed energy resources. These new networks have several protection issues; some are related to the high fault and load current variations due to the various operating conditions.

Space Weather, Volume 20, Issue 1, January 2022., 2022 Abstract We develop a new methodology for the multi‐resolution assimilation of electric fields by extending a Gaussian process model (Lattice Kriging) used for scalar field originally to vector field. This method takes the background empirical model as “a priori” knowledge and fuses real observations under the Gaussian process framework. The comparison

Journal of Nanomaterials, Volume 2022, Issue 1, 2022., 2022 Low‐voltage design is a challenge for Gilbert cell‐based mixers due to stacking transconductance and switching stage. This work addresses this issue by proposing a design of a low‐voltage down‐conversion mixer for band #1 of multiband orthogonal frequency division multiplexing (MB‐OFDM) system in 180 nm complementary metal oxide semiconductor (CMOS ...

Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 In this paper, we focus on the vehicle‐to‐vehicle dynamic channel in tactical communication environments, which shows time‐varying and nonstationary characteristics due to the fast mobility, directional antennas, and harsh terrain. These situations present great challenges for the channel state information (CSI) acquisition.

Plant Breeding, Volume 139, Issue 6, Page 1299-1309, December 2020., 2020 Abstract Pollen sterility (PS) in mother lines is crucial for hybrid crossings in plant breeding. 21 di‐ (2x) and tetraploid (4x) accessions of the hermaphroditic chamomile were screened for spontaneous, thermic or gametocide induced PS. Two crossing trials with the diploid accessions 'Bona' (BON) and 'Hungary 2' (HUN2) should specify maternally ...

Design of Broadband Band‐Pass Filter with Cross‐Coupled Line Structure
International Journal of Antennas and Propagation, Volume 2020, Issue 1, 2020., 2020 This paper presents a broadband band‐pass filter with cross‐coupled line structure. The cross‐coupled line structure is composed of the parallel coupled lines and an open stub. It can be analyzed by the odd‐ and even‐mode method due to its symmetric structure. There are three transmission poles in the passband and two transmission zeros out of passband.

Advances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020 Liquefied natural gas (LNG) leaks often lead to cascading accident disasters, including vapor cloud release, explosion, fire, and toxic gas release. The origin and evolution of each accidental disaster must be considered when assessing safety. This paper discusses the safety assessment project of an LNG gas storage station in Xuzhou, China.

Predictive Functional Control‐Based Zenith Pass Controller Design for Roll‐Pitch Seeker
International Journal of Aerospace Engineering, Volume 2020, Issue 1, 2020., 2020 A roll‐pitch seeker has a wide field of view but suffers from a singularity as the sightline coincides with the outer gimbal (OG) axis. In the vicinity of the singularity, the tracking effectiveness is often degraded or even lost due to the high actuation demand on OG, which is known as the zenith pass problem.
