In recent years, there has been a large increase in the use of uncrewed attack aircraft, or attack drones, in the Yemen conflict. At the same time, the flight endurance and payload capabilities of these uncrewed aerial vehicles seem to have increased significantly. This article presents a flight performance …

This artistic research report explores the functional possibilities of three extended instrumental techniques for the saxophone, uncovering and applying discovered conceptual principals for their use in composition, performance and improvisation which allow for saxophonists to occupy non-traditional …

Purpose As oral communication in higher education is vital, good classroom acoustics is needed to pass the verbal message to university students. Non-auditory factors such as academic language, a non-native educational context and a diversity of acoustic settings in different types of classrooms affect …

The prediction of mechanical elastic response of laminated hybrid polymer composites with basic carbon nanostructure, that is carbon nanotubes and graphene, inclusions has gained importance in many advanced industries like aerospace and automotive. For this purpose, in the current work, a hierarchical, …

Current methods for energy diagnosis in heating, ventilation and air conditioning (HVAC) systems are not consistent with process and instrumentation diagrams (P&IDs) as used by engineers to design and operate these systems, leading to very limited application of energy performance diagnosis in practice. …

The increase in consumption of resources has led to more waste being generated, which then needs to be managed at the end of their life-cycle as waste. Current practices of waste management are not efficient as they lead to a release of emissions and a loss of value that is present in the resource, which …

Background: Clinicians are currently challenged to support older adults to maintain a certain level of Functional Independence (FI). FI is defined as "functioning physically safely and independent from another person, within one's own context". A Core Outcome Set was developed to measure FI. The purpose …

Purpose: The present study deals with the numerical modeling of the low-velocity impact damage of laminated composites which have increasingly important applications in aerospace primary structures. Such damage, generated by various sources during ground handling, substantially reduces the mechanical …

Authors in previous studies pointed out that the professional competences of managers overlap with the competences and skills that are attributed to entrepreneurs. The goal of this study is to analyze the correlation between the actual market demand for competences to develop new businesses and the competence …

tract Micro wind turbines can be structurally integrated on top of the solid base of noise barriers near highways. A number of performance factors were assessed with holistic experiments in wind tunnel and in the field. The wind turbines underperformed when exposed in yawed flow conditions. The theoretical …
