A numerical study of high-speed (with the velocity of 250 m/s) impact of a liquid cone (cone-like jet) on a plain rigid wall has been performed.The range of the angles of inclination of the cone surface to the wall corresponds to that of their variation in the process of impact on the wall of a cylindrical jet with 910-005270 the semi-spherical end
This study aims to examine the effect of operating cash flow and return on assets on stock returns with accounting profit as a moderating variable.The sample technique used purposive sampling on LQ 45 listed companies (IDX) for the period 2016-2018, because the samples were taken using certain criteria and obtained 20 companies as research samples.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the current global COVID-19 pandemic, in which millions of lives have been lost.Understanding the zoonotic evolution of the coronavirus may provide insights for developing effective vaccines, monitoring the transmission trends, and preventing new zoonotic infecti
The global pandemic generated a crisis 910-005270 of still unpredictable consequences, further aggravated by the war in Ukraine.In 2008 a broad consensus had emerged on the need for far-reaching reforms, which basically meant doing away with the neoliberal consensus that had prevailed since the 1980s, although the chances of recovery were soon made
In this paper, we present the dynamic modeling and controller design of a tendon-driven system that is antagonistically driven by elastic tendons.In the dynamic modeling, the tendons are approximated as linear axial springs, neglecting their masses.An overall equation for motion is established by following 11m-be0023dx the Euler-Lagrange formalism
