Design and Implementation of an Efficient Tracking Differentiator

IEEE Access, 2019
Differential signals play significant roles in control practices, but they are prone to noise corruption. A noise-tolerant time-optimal system-based tracking differentiator (TD) was first proposed by Jingqing Han, which is constructed in the form of ...

VMD–WT-Based Method for Extracting On-the-Fly GNSS Tide Level and Its Realization

Remote Sensing, 2022
In this paper, a method for extracting the on-the-fly (OTF) GNSS tide level was designed by combining variational modal decomposition (VMD) and a wavelet thresholding (WT) method to improve the extraction accuracy of the OTF GNSS tide level.

⊤-Nets and ⊤-Filters.

TFSS, 2022
In this paper‎, ‎we develop a theory of $\top$-nets and study their relation to $\top$-filters‎. ‎We show that convergence in strong $L$-topological spaces can be described by both $\top$-nets and $\top$-filters and both concepts are equivalent in the sense that definitions and proofs that are given using $\top$-filters can also be given using $\top ...

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...
