Experimental and Numerical Analysis of the Aerodynamic Characteristics of the Flexing Wing With Active Camber Design

International Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.
The flexing/morphing concept is a means of improving wings’ aerodynamic performance. Morphing technology such as the fishbone active camber (FishBAC) design has demonstrated drag reduction of over 30% at moderate angles of attack (AoAs) and 40% at higher AoAs and tail deflections compared to plain flap systems.

Hypersoft sets with weight-based SVM for medical uncertainty modeling: A case study in heart disease diagnosis [PDF]

Journal of Fuzzy Extension and Applications
The HyperSoft Set (HSS) is a powerful tool for Multi-Criteria Group Decision-Making (MCGDM) problems because it expands on the concept of the soft set by combining many sets of qualities. The function F in this framework is a multi-argument function. The

Antijamming Improvement for Frequency Hopping Using Noise-Jammer Power Estimator

Applied Sciences, 2020
In frequency-hopping spread-spectrum (FHSS) systems, jammer detection and mitigation are important but difficult. Each slot of the FHSS experiences frequency-selective fading and unequal transceiver-frequency gains that hinder the detection of jammed ...

Australian first home ownership assistance schemes: International comparison and assessment

Australian Economic Papers, Volume 63, Issue 3, Page 507-529, September 2024.
Abstract Australia, like most developed countries, has promoted homeownership as an express housing policy goal for many decades. Domestically and internationally, recent years have seen growing efforts to enhance access to owner‐occupation for prospective first home buyers (FHBs). FHB assistance takes many forms.
