Influences of aerodynamic parameter uncertainties for UFSC based flight trajectory generation
SICE Journal of Control, Measurement, and System Integration, 2023 This paper discusses the model identification of a biplane which has superior lift generation capability and the influences of identification errors on trajectory generation using updating final-state control (UFSC). Aerodynamic parameters are identified

Adaptive Convex Optimization Guidance for Lunar Landing
Aerospace, 2023 In this paper, a novel guidance algorithm based on adaptive convex optimization is proposed to ensure robustness in the uncertainty of a lunar lander’s parameters and satisfy the constraints of terminal position, velocity, attitude, and thrust.

Magnetometry via a double-pass continuous quantum measurement of atomic spin
, 2009 We argue that it is possible in principle to reduce the uncertainty of an atomic magnetometer by double-passing a far-detuned laser field through the atomic sample as it undergoes Larmor precession. Numerical simulations of the quantum Fisher information

Diagnostics of Data-Driven Models: Uncertainty Quantification of PM7 Semi-Empirical Quantum Chemical Method. [PDF]
, 2018 We report an evaluation of a semi-empirical quantum chemical method PM7 from the perspective of uncertainty quantification. Specifically, we apply Bound-to-Bound Data Collaboration, an uncertainty quantification framework, to characterize (a) variability

Thrombolytic proteins profiling: High‐throughput activity, selectivity, and resistance assays
FEBS Open Bio, EarlyView.We present optimized biochemical protocols for evaluating thrombolytic proteins, enabling rapid and robust screening of enzymatic activity, inhibition resistance, and fibrin affinity, stimulation, and selectivity. The outcome translates to key clinical indicators such as biological half‐life and bleeding risk. These assays streamline the development of

Fault-Tolerant Control for Actuator Faults of Wind Energy Conversion System
Energies, 2019 The problem of robust fault-tolerant control for actuators of nonlinear systems with uncertain parameters is studied in this paper. Takagi−Sugeno (T-S) fuzzy model is used to describe the wind energy conversion system (WECS).

FEBS Open Bio, EarlyView.Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

Wind Turbine Structural Load Reduction by Linear Single Model Predictive Control
IEEE Access, 2020 A new model-based predictive controller (MPC), specially oriented to facilitate its practical implementation, is presented. This controller is devoted to reduce the structural load in the drive train or/and the rotor of a wind turbine.

Bayesian estimation of copula parameters for wind speed models of dependence
IET Renewable Power Generation, 2021 Modelling the uncertainty of wind speed is essential in power flow analysis. Having abundant knowledge of the wind speed in an area is critical. A low volume of data can increase uncertainty in wind speed analysis. Spatial dependencies are often modelled
