Development of an Intelligent and Statistical Model for Prediction of Rock Mass Deformation Modulus
Abstract: The rock mass deformation modulus (Em) takes into account the plastic and the elastic deformation of the rock mass. It has been widely used for designing structures such as dams, tunnels, caverns, and mines, etc. Since the tests available for ascertaining Em are expensive and time consuming, several equations were suggested in the past. However, it has been found that the existing models are limited to specific type of rock …

Predictability of Equation of State (EoS)-based Gas Hydrate Models for Single and Binary Gas Mixtures
Abstract: The better models are necessary to design and understand the phase behavior of produced trapped natural gas from natural gas hydrates from subsea environments. Most of the models available in an open literature are primarily applicable at relatively low pressure condition thus making their use very limited for gas hydrate reservoir modeling. In order to produce methane from these gas hydrates, it is important to understand the phase behavior through …

Breathing prediction of fracture deviated wellbore through flooding mechanism
Abstract: Wellbore breathing is a common occurrence during drilling operations, but the down hole mechanism and how it manifests itself in surface and subsurface processes, is not well understood. It often result in a drilling fluid gain at surface and are misidentified as a kick, resulting in unneeded shut in periods and associated non-productive time (NPT). Further, misidentification of wellbore breathing as underbalance often results in increases in mud weight, which …

Model to Predict the Non-Competitive Inhibition of Petroleum Hydrocarbon Degradation
Abstract: This investigation involves the development of model to predict the non-competitive inhibition of petroleum hydrocarbon degradation. The result of the model shows the relation between the substrates concentration (hydrocarbon) with time. It was observed that at a very small rate the substrate decrease upon the act of the inhibitor. The non-inhibitor is such that it influences the growth rate of the enzymes substrate formation but attacking not necessarily the active …

Prediction of Transformer Oil Parameters Using UV/VIS Spectroscopy Graphs
Abstract: AbstractUltraviolet–visible rays (UV/VIS) spectroscopy is a method based on a spectrum, which forms a graph between radiations absorbed by the material and the wavelength of the radiations. UV/VIS spectroscopy is able to tell the impurities or decay contents present in any sample material. In this paper, we have used data collected from various tests performed on the transformer oil samples and compared these results with the UV/VIS spectroscopy results. This …

Predicting diabetes status using ensemble algorithms with hyperparameter tuning
Abstract: Diabetes is a condition in which the body is unable to produce enough insulin to keep blood sugar levels under control. If diabetes is not properly identified and treated, it can lead to kidney failure, nerve damage, blindness, and coronary heart disease. A healthy lifestyle, therefore, depends on the early identification of diabetes diseases. However, it can be difficult to assess a person's diabetic status if they live in remote …
