Abstract Porosity and facies are two main properties of rock which control the reservoir quality have significant role in petroleum exploration production. Well seismic data most prevalent information for characterization. such as logs prepare adequate vertical resolution but leave a large distance between wells. In comparison, three-dimensional can more detailed characterization inter-well spa...

In this paper, we investigate software fault detection and fault correction processes based on infinite server queuing model which incorporate testing effort functions. Some researches proposed in the literature to study fault detection and fault correction processes. However, most of them do not consider the amount of resources consumed during fault detection and fault correction processes. Th...

in this research, a new mathematical modeling on strength changes due to reservoir elastic stresses across the preexisting fault plane is introduced. the method has been applied to the dalpari fault, which is one of the potential seismic sources in the vicinity of the karkheh reservoir. in this method the distribution of total stress across the fault cannot be determined because the initial str...

in this study, detection and identification of common faults in industrial gas turbines is investigated. we propose a model-based robust fault detection(fd) method based on multiple models. for residual generation a bank of local linear neuro-fuzzy (llnf) models is used. moreover, in fault detection step, a passive approach based on adaptive threshold is employed. to achieve this purpose, the a...

Fault tolerance property of artificial neural networks has been investigated with reference to the hardware model of artificial neural networks. Weight fault is an important link, which causes breakup between two nodes. In this paper weight fault has been explained. Experiments have been performed for Weight-stuck-0 fault. Effect of weight-stuck-0 fault on trained network has been analyzed in t...

Active fault isolation of parametric faults in closed-loop MIMO systems are considered in this paper. The fault isolation consists of two steps. The first step is groupwise fault isolation. Here, a group of faults is isolated from other possible faults in the system. The group-wise fault isolation is based directly on the input/output signals applied for the fault detection. It is guaranteed th...

Different fault reasoning techniques are used in fault localization for either deterministic or probabilistic fault causality model. Symptom-Fault map is commonly used to describe Symptom-Fault causality in fault reasoning. However lost and spurious symptoms severely affect both performance and accuracy of fault reasoning. In this paper, we propose an extended Symptom-Fault-Action model to inco...

Abstract Due to the growing need for hydrocarbons and limited conventional resources, paying attention unconventional oil gas resources is essential. The upper Jurassic-Lower Cretaceous in western southwestern Iran contains most crucial source rocks of Zagros sedimentary basin. One richest shaly Garau Formation. Owing geochemical geological characteristics, Formation, with Neocomian Coniacian a...
