This paper proposes a low-voltage ridethrough (LVRT) capability for a doubly-fed induction generator (DFIG) wind turbine (WT) system. With the proposed method, series grid-side converter (SGSC) in which its DC-side connected at the DC bus of the back-toback converters and its AC-side connected in series with line through transformer have been applied, enables to compensate a voltage response of the system during the grid faults and to reduce the capital cost.

A corotational finite element for large-displacement elastic analysis of semi-rigid planar steel frames is proposed in this paper. Two zero-length rotational springs are attached to the ends of the Euler-Bernoulli element formulated in corotational context to simulate the flexibility of the beam-to-column connections and then the equilibrium equations of the hybrid element, including the stiffness matrix which contains the stiffness terms of the rotational springs, are established based on the static condensation procedure.

Recent advancements in metagenomics, particularly in the studies of conservative 16S rRNA sequences, have significantly accelerated our understanding of the relationship between corals and their associated microbial communities. While bacteria are known to be closely linked with corals, there is limited understanding of the connections between archaea and corals. Unlike previous 16S rRNA studies conducted in similar tropical coral reef ecosystems, we analyzed both the archaeal and bacterial communities associated with Acropora sp. and Lobophyllia sp.

This article evaluates and compares the punching shear behaviour of unbonded prestressed concrete (UPC) slab - concrete-filled steel tube (CFT) column connections/joints with that of reinforced concrete (RC) slab – CFT column connections. The experimental program was carried out on five large-sized samples, including three UPC slab - CFT column samples and two RC slab - CFT column samples.

We use the conditional granger causality framework to investigate the connectedness among the most globally traded currencies from three perspective namely node-wise, group-wise and system-wise connectedness. Empirically, Global currencies tend to form into communities based on connection strength and density. While more links are found for emerging market currencies, the G11 currencies are net return- shock transmitters.
