A new numerical well testing approach: Application to characterization of complex fault structures

Petroleum, 2019
Fluid flow in hydrocarbon reservoirs and consequently optimum scenario for hydrocarbon production, is heavily influenced by reservoir heterogeneities. Faults are one of the most common types of heterogeneity found in reservoirs.

Remarks on the O(N) Implementation of the Fast Marching Method

, 2007
The fast marching algorithm computes an approximate solution to the eikonal equation in O(N log N) time, where the factor log N is due to the administration of a priority queue. Recently, Yatziv, Bartesaghi and Sapiro have suggested to use an untidy priority queue, reducing the overall complexity to O(N) at the price of a small error in the computed ...

Cognitive Performance in Early Neuronal Synuclein Disease with Hyposmia but without Motor Disability: Association with Dopamine Deficiency and Isolated Rapid Eye Movement Sleep Behavior Disorder

Annals of Neurology, EarlyView.
Objective To determine the impact of dopamine deficiency and isolated rapid eye movement (REM) sleep behavior disorder (iRBD) on cognitive performance in early neuronal α‐synuclein disease (NSD) with hyposmia but without motor disability. Methods Using Parkinson's Progression Markers Initiative baseline data, cognitive performance was assessed with a ...

Locating Traces of Arboreal Beings: Connecting the Tree and the Woodblock

Archaeology in Oceania, EarlyView.
ABSTRACT Woodblocks for printmaking are multi‐perspectival communicators inscribed with layered narratives. The artistic process of cutting excavates the surface of a woodblock, making visible lesser‐seen traces of the past, reflective of the practice of archaeology.

Multidisciplinary Approach to Identifying Early Mediaeval Gates: A Case Study of the Břeclav–Pohansko Stronghold

Archaeological Prospection, EarlyView.
ABSTRACT This study presents a comprehensive approach to verifying a presumed western gate at Pohansko by integrating nondestructive geophysical methods (ERT, magnetometry and core prospection) with traditional archaeological excavation. The identification and characterization of gates by nondestructive methods within early mediaeval fortified sites ...
