Classifying rocks based on core data is the most common method used by geologists. However, due to factors such as drilling costs, it impossible obtain samples from all wells, which poses challenges for accurate identification of rocks. In this study, authors demonstrated application an explainable machine-learning workflow using and log identify rock types. The type determined utilizing flow z...

a = index referring to the lumped mass ‘a’ b = index referring to the lumped mass ‘b’ Fxi = X component of the inertial force acting on the i-th lumped mass (i = a or b) Fyi = Y component of the inertial force acting on the i-th lumped mass (i = a or b) Fzi = Z component of the inertial force acting on the i-th lumped mass (i = a or b) R = half of the distance between the two arms (bars) in par...

Unit A of Kurra Chine Formation has been studied in the well Shaikan - 4 (SH-4) at Oilfield Northern Iraqi Kurdistan Region. The available conventional wireline log data and existed core test values have used to characterize reservoir properties unit determine flow efficiency reservoired fluids. dolomite anhydrite dominated lithology contains low percentages shale except upper most part which c...

Using the Hβ linewidth, we obtained the virial central supermassive black hole masses and then the Eddington ratios in a sample of broad-line AGNs and NLS1s observed by ASCA. Combined with the data from ROSAT and Chandra observations, We found a strong correlation between hard/soft X-ray photon index and the Eddington ratio. Such a correlation can be understood by a two-zone accretion flow mode...

Environmental flow requirements, to maintain the functioning of freshwater-dependent ecosystems and restore rivers in ecologically acceptable conditions, depend upon the present water quality status of the river. Various stretches of Vishwamitri River vary in quality and quantity. Water quality index is a tool to converse information regarding water quality of various stretches of river and can...

The Upper Pannonian (UP) sandstone formation has been utilised for thermal water production in Hungary several decades. Although sustainable utilisation requires the reinjection of cooled geothermal brine into host rock, only a fraction used is reinjected country. UP reported to exhibit low injectivity, making challenging, and its petrophysical properties are poorly known, which increases uncer...

[1] The experimental evidence suggests that for many chemicals surface runoff and rapid preferential flow through the shallow unsaturated zone are significant pathways for transport to streams and groundwater. The signature of this is the episodic and pulsed leaching of these chemicals. The driver for this transport is the timing and magnitude of rainfall events which trigger rapid flow and the...

Coordinated Atomic actions (CA actions) are a unified approach to structuring complex concurrent activities and supporting error recovery between multiple interacting objects in object-oriented systems. This paper explains how we have used the CA action concept to design and implement a safety-critical application. We have used the Production Cell model that was developed in the Forschungszentr...
