Framework for state and unknown input estimation of linear time-varying systems

, 2016
The design of unknown-input decoupled observers and filters requires the assumption of an existence condition in the literature. This paper addresses an unknown input filtering problem where the existence condition is not satisfied.

Meta-heuristic algorithms in car engine design: a literature survey [PDF]

, 2015
Meta-heuristic algorithms are often inspired by natural phenomena, including the evolution of species in Darwinian natural selection theory, ant behaviors in biology, flock behaviors of some birds, and annealing in metallurgy.

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

FEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Reducing the Effects of Inaccurate Fault Estimation in Spacecraft Stabilization

Journal of Aerospace Technology and Management, 2017
Reference Governor is an important component of Active Fault Tolerant Control. One of the main reasons for using Reference Governor is to adjust/modify the reference trajectories to maintain the stability of the post-fault system, especially when a ...

Decentralized Fuzzy Observer-Based Fault Estimation for Nonlinear Large-Scale Systems

IEEE Access
This paper presents a fault estimation technique based on the decentralized fuzzy observer for nonlinear large-scale systems, which are considered to be consisted of fuzzy subsystems and uncertain interconnections.

Fault Estimation and Fault Tolerant Control Strategies Applied to VTOL Aerial Vehicles With Soft and Aggressive Actuator Faults

IEEE Access, 2020
Actuator Fault Estimation (FE) and Fault Tolerant Control (FTC) strategies designed with model-based observers for Vertical Take-Off and Landing (VTOL) aerial vehicles are proposed and validated experimentally in this paper.

Distributed fault estimation with randomly occurring uncertainties over sensor networks [PDF]

, 2016
This paper is concerned with the distributed fault estimation problem for a class of uncertain stochastic systems over sensor networks. The norm-bounded uncertainty enters into the system in a random way governed by a set of Bernoulli distributed white ...

Wasatch fault damage estimate

Eos, Transactions American Geophysical Union, 1979
Studies of ground motion caused in the Salt Lake City, Ogden, and Provo, Utah, areas by underground nuclear tests suggest that a moderate earthquake in the region could cause significant damage.Walter W. Hays, USGS seismologist, Golden, Colorado, said that the studies indicate that soils in some parts of the Utah urban corridor along the Wasatch fault ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).
