the kopet-dagh basin extended in the north and north east of iran and consists of marine strata from middle jurassic to paleogene time. abtalkh formation is one of the thickest lithostratigraphic units of cretaceous in the kopet-dagh basin and is composed of light gray, green to bluish marl and silty marl. the abtalkh formation conformably overlies the marls and chalky limestones of the abderaz...

Abstract In the present work we discuss results of a number Schmidt hammer tests (total impacts N > 2,400) that were performed in situ on rock outcrops different lithology (marl, calcareous marl, limestone, sandstone, quartz sandstone and rhyolite) occur Italy. Firstly, specific field procedure to choose reference value rebound index adopted calculate UCS intact is suggested. A relationship ...

In this paper, we propose a novel method of reward design for multi-agent reinforcement learning (MARL). One the main uses MARL is building cooperative policies between self-interested agents. We take inspiration from concept mechanism game theory to modify how agents are rewarded in algorithms. defined payment that reflects negative contribution other agents’ valuation same manner as Vickrey-C...

Deep Reinforcement Learning has made significant progress in multi-agent systems recent years. The aim of this review article is to provide an overview approaches on Multi-Agent (MARL) algorithms. Our classification MARL includes five categories for modeling and solving cooperative reinforcement learning problems: (I) independent learners, (II) fully observable critics, (III) value function fac...

Hydrochemical patterns across groundwater-fed wetlands, especially carbonate and redox gradients, can influence phosphorus (P) availability by controlling its distribution among different soil pools. We explored these linkages by comparing shallow (5–20 cm) soil properties along groundwater flowpaths in two rich fens, a marl fen, and a poor fen. Organic matter content, bulk density, and total e...

This study aims to compare two approaches for the reserve calculation of cement raw material by geological sections and structural maps. The first is legally based, its accuracy approved periodical exploited on site. In this research, it was crucial determine deviation in approach, i.e., section volume versus obtained as a software solution estimated number cells between maps, maps interpolated...

Network slicing (NS) management devotes to providing various services meet distinct requirements over the same physical communication infrastructure and allocating resources on demands. Considering a dense cellular network scenario that contains several NS multiple base stations (BSs), it remains challenging design proper real-time inter-slice resource strategy, so as cope with frequent BS hand...
