A literature review of QSPR approaches to predict jet fuel properties. It exposes the fundamental principles of QSPR and illustrates pure‐compound QSPR through examples of applications for jet fuel components. Mixture‐QSPR (M‐QSPR) modeling specificities are addressed: mixtures representation, design of descriptors for mixtures, and impact on internal ...

Major Space Weather Risks Identified via Coupled Physics‐Engineering‐Economic Modeling
Abstract Space weather poses an important but under‐quantified threat to society. While severe geomagnetic storms are recognized as potential global catastrophes, their socio‐economic impacts remain poorly quantified. We present a novel physics‐engineering‐economic framework that links geophysical drivers to power grid geoelectric fields, transformer ...

Comparative Analysis of Fourth-Order Non-Isolated DC-DC Converters: Ćuk, SEPIC and Zeta [PDF]
This paper presents a comparative study of three fourth-order non-isolated DC-DC converters: Ćuk, SEPIC, and Zeta. Analytical expressions for output voltage ripple were derived for each topology, and their accuracy was validated through numerical ...

Realization of a Photovoltaic Fed Sparse Alternating Current (AC)-Link Inverter
In this paper, a soft-switched alternating current (AC)-link buck-boost inverter with a reduced number of switches, referred to as a sparse AC-link buck-boost inverter, was designed and implemented for a photovoltaic (PV) interface. Important features of
