“…According to multiple research, including (Kim and Rhee, 1997), (Singh and Shukla, 2020), (Nelson, 1991) EGARCH mannequin is the super specification for modeling stock index (Teniwut et al, 2019). This was also looked at in some subsequent experiments, such as a web search (Krause and Tse, 2013).…”

This study points to increase global monetary integration as a result of rising volatility spillovers. As a result, analyzing volatility spillovers for international areas that expand and improve through the usage of inventory returns and oil prices is critical. The EGARCH model is used to explore the Volatility Spillovers of oil agencies in five ASEAN international areas during the Covid-19 Pandemic. To assess the interrelationships of the ASEAN stock index as well as the path of volatility, data were acquired from five global sites with very large volatility spillovers, namely Indonesia, Malaysia, Singapore, Thailand, and Vietnam. The findings show that this search is critical for ASEAN traders as well as Filipinos. Furthermore, because accurate forecasting of volatility spillover in global equity markets is required to reduce portfolio risk, this search has a substantial and viable significance.

“…In the last decade, there has been a significant increase in interest in the use of an abrasive water jet for the micromachining [ 29 , 30 ]. These applications are accompanied by a number of technical difficulties that need to be resolved [ 31 , 32 ]. These problems result in the new challenges that await scientists in this area [ 33 , 34 ].…”

Analysis of Several Physical Phenomena Measured on the Metallic Materials Cut by Abrasive Water Jets (AWJ)

Cutting using an abrasive water jet is a complex process involving several physical phenomena. This research studies some of them, mostly the influence of selected variables on the measured forces and vibrations. The traverse speed represents one of the key parameters when cutting using the AWJ. In the presented research, a set of experiments was performed on twelve different metal samples, while the force sensor measured the exerted forces and accelerometers measured the vibrations. Ten different types of steel samples of the same dimensions were cut applying five different traverse speeds. The data obtained during these measurements show that an increase in the traverse speed leads to an increase in the measured forces and vibrations. An analogous experiment performed on bronze and duralumin samples of the same dimensions, having applied higher speeds to compensate for the difference in the material structure and properties, completes the presented data. The most important results of the research are that exerted forces in the z-axis are higher than those in the x-axis, whereas measured vibrations are higher in the x-axis. According to our research, the elemental structure, especially the carbide formation, affects the measured forces and vibrations substantially.
