Background: Drilling is one of the most widely used process in orthopaedic surgical operation and the same drill bit is used a number of times in hospitals. Using the same drill bit a several times may be the cause of osteosynthesis and osteonecrosis. Methods: In the present work, the effect of repeated orthopaedic surgical twist drill bit on the tool wear, force, torque, temperature and chip m...
Deep Deterministic Policy Gradient (DDPG) algorithm is one of the most well-known reinforcement learning methods. However, this method inefficient and unstable in practical applications. On other hand, bias variance Q estimation target function are sometimes difficult to control. This paper proposes a Regularly Updated (RUD) policy gradient for these problems. theoretically proves that procedur...
Developing a Model for the Integrated Management of Water and Soil Resources in Hableh-Rud River Basin Using System Dynamics Approach
To reduce dependence on foreign oil reserves, there has been a push in North America to develop alternative domestic energy resources. Relatively undeveloped renewable energy resources include biofuels and wind and solar energy, many of which occur predominantly on rangelands. Rangelands are also key areas for natural gas development from shales and tight sand formations. Accordingly, policies ...
Rud syndrome is a rare disease entity that consists of congenital ichthyosis, mental retardation, hypogonadism, and epilepsy. In this article two cases that are sibling are reported. The parents are relative. The elder one who is a 16-yr old female suffers from sever ichthyosis, hypocalcemic tetany, sever mental and grown retardation, and hypogonadism. In the second patient a 9-yr old male the ...
and call a set A provident if it is transitive and closed under all p-rud-rec functions with p a member of A. * If ζ is the least ordinal not in a provident set A, then ζ is indecomposable, that is, that the sum of two ordinals less than ζ is less than ζ. Conversely, if ζ is indecomposable, η > ζ and p ∈ Jζ , then the Jensen set Jη is is closed under all p-rud rec functions; in particular Jζ is...
Determination of landscape evolution is useful to well understand the physical environment and it also enables us to conduct the soil related studies. The objective of this study was to establish the historic evolution of Zayandeh-rud Valley from late Tertiary to Quaternary. To achieve this objective, the spatial structure of a representative area of Zayandeh-rud Valley in three dimensions was ...
