dynoGP: Deep Gaussian Processes for Dynamic System Identification

International Journal of Adaptive Control and Signal Processing, EarlyView.
This work introduces a novel class of deep models for system identification, dynamical deep Gaussian processes, which combine the strengths of data‐driven methods, such as those based on neural network architectures, with the ability to output a probability distribution for uncertainty representation.

Delay‐dependent small‐signal stability analysis of inverter‐based islanded microgrids

IET Smart Grid
The stability of an inverter‐based hierarchical microgrid is challenged by inverter controls, network dynamics, load models and communication delays among the interacting agents.

Online identification of stability region for large-scale wind farms, Part II: Construction of stability region boundary

International Journal of Electrical Power & Energy Systems
The operating point of wind farms changes in a wide range, leading to diverse performances of small-signal stability. The mapping between the stability index and the operating point is complex.

Stability of an Elastic Column Subjected to Non-Stationary Compressive Loads

Engineering Transactions, 2005
The problem of dynamic stability of an elastic column with pinned ends subjected to non-stationary compressive axial loads is considered. The method of optimal Lyapunov functions for differential inclusions is applied to obtain sufficient conditions of ...

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Interval analysis of the small‐signal stability of grid‐connected voltage‐source converter system considering multiparameter uncertainty

IET Energy Systems Integration
Grid‐connected voltage source converters (VSCs) have been broadly applied in modern power system. However, instability issues may be triggered by the integration of grid‐connected VSCs, jeopardising the operation of the power grid. Conventional stability

Extensive and intensive trade margins: a state-by-state view [PDF]

This paper examines a topic of increasing interest, the potential determinants of extensive (i.e., number of firms) and intensive (i.e., average exports per firm) trade margins, using state-level trade to 190 countries.

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

Advanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Iberian Atlantic Margins

, 1995
The IAM project was part of an effort to study the deep geology of Europe. In particular the project aimed at exploring the nature of the deep continental and oceanic crust of the Earth in selected areas of the Atlantic margins of Iberia for a better ...
