Reinforcement learning scales poorly when reinforcements are delayed. The problem of propagating information from delayed reinforcements to the states and actions that have an e ect the reinforcement is similar to the problem of propagating information in a discretized boundary value problem. Multigrid methods have been shown to decrease the number of updates required to solve boundary value pr...

The increase of shear strength in soil, reinforced with the geogrid (alternate reinforcer), is resulted from an increase of modulus of soil hardness, and also from the tensile strength of reinnforcer. The shear strength of contact surface in soil appears due to both the friction strength against the contact surface, and the passive strength formed in front of the elements of the geogri...

Abstract: It is easy for composite laminates to be damaged by relative lower velocity impact which could give rise to internal delamination that will strongly weaken the compressive strength of laminates. In order to predict the occurrence of matrix failure, the elastic-brittle behaviors of fiber-reinforced composites were modeled constitutively by an anisotropic damage model. The dynamic tensi...

This paper proposes a novel and environmentally friendly solution for subgrade stabilization that not only contributes towards waste material recycling but also enhances the bearing capacity of soil. Laboratory plate load tests were conducted under static loads to evaluate potential use palm tree pruning (PTPW) as soil reinforcement instead commercially manufactured geotextiles, well analyse im...

Materials Research Group (CMRG) at the University of Mississippi (UM) have recently begun a research study supported by the U. S. Department of Agriculture (NRICSREES-USDA Award number 2003-35504-13627) examining natural fiber reinforcements (NFR). The objectives of this research are to demonstrate the feasibility of using the cost-effective pultrusion process to manufacture high quality polyme...

Two-dimensional model tests combined with PIV technology were conducted to study the failure behavior of strip footing on geosynthetic-reinforced granular soil foundations a mesoscale. The results showed that geosynthetic reinforcements improve bearing capacity foundations; however, effectiveness reinforcement was affected by position, length, and number geosynthetics. mesoscale factor affectin...

This study contrasts different instructional reinforcements in the teaching of phonetics, i.e., learning tasks that supplement a classroom lecture on a phonetic contrast. 152 introductory linguistics students were split into four groups, each of which received the same lecture but a different instructional reinforcement, as follows: (1) a baseline textbook-style handout explaining the contrast,...
