A scalar potential of the form aba^2b^2 is bounded from below if its matrix of quartic
couplings λ ab is copositive—positive on non-negative vectors. Scalar potentials of this form …

In this article, we address the simultaneous estimation problem of the lateral speed, the
steering input, and the effective engine torque, which play a fundamental role in vehicle …

Reducing the weight of concrete beams is a primary (beyond strength and durability)
concern of engineers. Therefore, this research was directed to investigate the impact …

This paper presents line search algorithms for finding extrema of locally Lipschitz functions
defined on Riemannian manifolds. To this end we generalize the so-called Wolfe conditions …

The use of uncrewed aerial vehicles (UAVs) in cell-free networks is poised to unleash a
number of new opportunities to further improve wireless networks. However, cell-free UAV …

In this article, we investigate a resource allocation problem for multicarrier multiuser MISO
(multiple-input-Single-output) downlink systems, where multiple co-channel multicast groups …

Membrane-based processes and thermal desalination plants are two alternatives to
overcome the problem of fresh water supply by means of seawater desalination. In this work …

Complex molecular biological processes such as transcription and translation, signal
transduction, post-translational modification cascades, and metabolic pathways can be …

Total hip joint replacement is a common procedure to retrieve the lower limp functionality for
motorcycle accidents, and hip fracture due to bone weakness. Stress shielding is the factor …

Further improvement of state-of-the-art low-pressure (LP) turbines (LPTs) has become
progressively more challenging. LP design is more than ever confronted to the need to …
