(Emerald Group Holdings Ltd., 2022)
Purpose: This paper aims to offer a simultaneous design approach for helicopter having swept anhedral blade tip shape and helicopter flight control system (HFCS) to minimize controller cost. Design/methodology/approach: ...
Analysis of Factors Affecting the Sustainable Success of Airlines During the COVID-19 Pandemic
(SAGE Publications, 2022)
The COVID-19 pandemic increased the risk of financial distress, bankruptcy, or both, in the airline industry. Whether airlines can survive or not during and/or after the pandemic is closely related to their decisions and ...
The Theoretical Value for the Tip Radius of Cracks and Notches
(Kauno Technologijos Universitetas, 2022)
In this paper, an additional equation that can be used in conjunction with the Stress Intensity Factor is produced, enabling the determination of all critical fracture stresses, including tensile strength, from only one ...
Low-Cost Antenna-Array-Based Metamaterials for Non-Invasive Early-Stage Breast Tumor Detection in the Human Body
(MDPI, 2022)
Microstrip patch antennas have been used in many applications since their appearance. Despite their great promise, their narrow bandwidth and the loss at high-frequency bands have limited their usage in medical applications. ...
The prediction of surface roughness and tool vibration by using metaheuristic-based ANFIS during dry turning of Al alloy (AA6013)
(Springer, 2022)
In this article, the adaptive neuro-based fuzzy inference system (ANFIS) model is developed to estimate the surface roughness (Ra) and tool vibrations (Acc) of AA6013 aluminum alloy during dry turning. Turning experiments ...
A comparison of four machine learning techniques and continuous wavelet transform approach for detection and classification of tool breakage during milling process
(Canadian Science Publishing, 2022)
In machining, the tool condition has to be monitored by condition monitoring techniques to prevent damage by the use of tools and the workpiece. Cutting forces acting on the tool between zero and maximum values cause the ...
Characterizations of Microstructure and Properties of Dissimilar AISI 316L/9Ni Low-Alloy Cryogenic Steel Joints Fabricated by Gas Tungsten Arc Welding
(Springer, 2022)
The demand for dissimilar joining of steel grades, namely austenitic stainless steels to low-alloy steels, may increase in near future owing to the fact that the storing of LNG is currently becoming a necessity, particularly ...
