SEDIMENTOLOGICAL STUDY OF THE HARTHA & SAADI FORMATIONS FROM SELECTED WELLS IN QAYARA OIL FIELD NORTHERN IRAQ [PDF]
The research included sedimentological study of Hartha and Saadi formations in Qayara oil fields: (QY53, QY84, QY82, QY54). The study indicates that the rocks of both formations are composed from limestone, dolomitic limestone, and dolomite which are ...

Unsupervised seismic facies classification using deep convolutional autoencoder [PDF]
With the increased size and complexity of seismic surveys, manual labeling of seismic facies has become a significant challenge. Application of automatic methods for seismic facies interpretation could significantly reduce the manual labor and subjectivity of a particular interpreter present in conventional methods.

Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated

Functional asymptotic confidence intervals for a common mean of independent random variables [PDF]
We consider independent random variables (r.v.'s) with a common mean $\mu$ that either satisfy Lindeberg's condition, or are symmetric around $\mu$. Present forms of existing functional central limit theorems (FCLT's) for Studentized partial sums of such r.v.'s on $D[0,1]$ are seen to be of some use for constructing asymptotic confidence intervals, or ...

Abstract Silesaurids (Archosauria: Dinosauriformes) are found in Middle to Upper Triassic deposits across Pangea, but few stratigraphic sections record the evolution of the group in one geographic area over millions of years. Here, we describe silesaurid remains from the oldest of the Upper Triassic stratigraphic sequence from the base of the Dockum ...
