In the present work, potential of an electronic nose to differentiate geographical origin Moroccan virgin olive oils based on their volatile profile was investigated. An gas sensor array system composed 6 metal oxide semiconductor sensors used generate a chemical fingerprint (pattern) compounds in oils. Multivariate statistical approach showed good discrimination between classes 27-sample dataset population. The results this study provide promising perspectives for use low-cost and rapid...
Kashmir valley lies in the Northwest part of seismically active Himalayan arc, is vulnerable to earthquakes both from near and far seismogenic sources owing its unique geological, geographical seismotectonic setting. The area has witnessed numerous colossal throughout prolific geological past causing severe damage natural built environment with intensity levels ranges between VIII–X. Recent data instrumental seismicity shows that very high peak ground accelerations can be generated by...
Abnormal increase in radon (222Rn, half-life = 3.82 days) concentration has frequently been observed soil gas environments before major earthquakes. This observation suggests that emission may be suitable for use as an earthquake precursor. The objective of this study is to evaluate the precursor and around northern Pakistan. For purpose, was monitored at foothills Maragalla, Islamabad. data presented work obtained using a monitor (RTM2200) ion-implanted silicon detector covers period from...
In the field of hyperspectral image (HSI) classification in remote sensing, combination spectral and spatial features has gained considerable attention. addition, multiscale feature extraction approach is very effective at improving accuracy for HSIs, capable capturing a large amount intrinsic information. However, some existing methods extracting can only generate low-level consider limited scales, leading to low results, dense-connection based enhance propagation cost high model...
Shales can be distributed in sand through four different ways; laminated, structural, dispersed and any combination of these aforementioned styles. A careful analysis well log data is required for the determination shale distribution affecting its reservoir quality. The objective this study to characterize effect on quality sands using data. correlation terms lithology has revealed three layers Lower Goru Formation acting as a major area. Our results indicate that laminated type prevails at...
ABSTRACT Attempts have previously been made to predict anisotropic permeability in fractured reservoirs from seismic Amplitude Versus Angle and Azimuth data on the basis of a consistent permeability‐stiffness model Gassmann relations Brown Korringa. However, these attempts were not very successful, mainly because effective stiffness tensor porous medium under saturated (drained) conditions is much less sensitive aperture fractures than corresponding tensor. We here show that one can obtain...
Abstract On 24 September 2019, an Mw 5.9 earthquake struck near the Mangla reservoir in northeastern Pakistan and resulted 39 fatalities 746 serious injuries, making it deadliest region since 2005 7.6 Kashmir earthquake. Here, we integrate geodetic, seismic, field observations to characterize source properties impact of Mirpur as well investigate whether might be a reservoir-induced event. From inverting Interferometric Synthetic Aperture Radar data, find that fault with strike ∼310°, dip...
We have investigated the accuracy of Rüger's approximation for PP reflection coefficients in HTI media (relative to an exact generalization Zoeppritz anisotropy derived by Schoenberg and Protazio) within context seismic fracture characterization. consider inverse problem amplitude-versus-angle azimuth (AVAZ) inversion with respect density azimuthal orientation, as well forward calculating different contrasts levels. The T-matrix approach was used relate contrast level parameters fractures...
