Covariant derivative of the curvature tensor of pseudo-K\"ahlerian manifolds
, 2016 It is well known that the curvature tensor of a pseudo-Riemannian manifold can be decomposed with respect to the pseudo-orthogonal group into the sum of the Weyl conformal curvature tensor, the traceless part of the Ricci tensor and of the scalar ...

Adaptive mixing formation control of multiquadrotor unmanned aerial vehicle systems
Asian Journal of Control, EarlyView.Abstract This paper presents a distributed adaptive mixing control (AMC) design for formation maintenance of systems of multiquadrotor UAVs (q‐UAVs) during commanded path‐tracking maneuvers. The proposed formation control scheme has a two‐level structure. The high level defines the desired trajectories for rigid and persistent formation acquisition and

A Short‐Cut Design Approach to Evaluate Reboiler Designs in Vapor Recompression Scenarios
Chemie Ingenieur Technik, EarlyView.A short‐cut model framework that incorporates mechanical vapor recompression (MVR) requirements into reboiler design is presented, which is particularly beneficial during early process development with limited data or initial feasibility assessments.

A Structurally Flexible Occupancy Network for 3-D Target Reconstruction Using 2-D SAR Images
Remote SensingDriven by deep learning, three-dimensional (3-D) target reconstruction from two-dimensional (2-D) synthetic aperture radar (SAR) images has been developed. However, there is still room for improvement in the reconstruction quality.

Corporate Sustainability Transition: Methodological Analysis for a Rating Model
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This study introduces a new rating model for the evaluation of corporate sustainability, addressing the inconsistencies and divergences that characterize current ESG assessment systems. The model is hierarchically structured, comprising 99 indicators organized into 19 modules, and is designed to be adaptable by sector and firm size.
