The mechanical model of a two-degree-of-freedom forced harmonic vibration system with multiclearance rigid constraints is established, considering the location schemes of symmetrical both-sided clearance and asymmetrical multiple clearance.Existence domains, here correlative distributions, and bifurcation scenarios of periodic vibrations are analyz
Automated Fiber Placement of thermoplastic unidirectional tape materials offers several advantages over conventional organosheets, such as enhanced part performance through tailored fiber architecture, and economic and ecological benefits due to scrap reduction.Because material is cut perpendicular to the feeding direction in state-of-the-art machi
This paper explored taxation and foreign direct investment (FDI) using the case of Nigeria with limited investigation.Taxation was proxy by company income tax (CITX) and value added tax (VATX), while FDI was proxy by FDI inflows.Data employed for the analyses were from 2000 to 2020 and obtained from Central Bank of Nigeria (CBN) Statistical Bulleti
Vegetable oils have been used as metalworking fluids (MWFs) for many years, particularly in small-scale metalworking operations and in industries where environmental regulations are strict.Before the development of modern MWFs, vegetable oils were one of the most common lubricants used for metalworking tools.The use of vegetable oils can be traced
