Asphaltene precipitation and deposition can occur at both the surface subsurface levels, leading to formation of organic-based scales. also lead changes in petrophysical properties such as wettability, which affects ultimate recovery. is linked fluid composition driven by pressure drawdown temperature variation across reservoir. Thus, asphaltene adversely influence Thermal recovery methods are ...

Satan has captured the imagination of writers in the English language for centuries. This figure and the notion of evil have gone through many changes in English literature of the 19 and 20 centuries. Something changed Satan during this time, and made him into an arbiter of truth rather than a figure of rebellion. In The Mysterious Stranger, Mark Twain used him as the grand narrator of the univ...

We show that it is always possible to transform the problem of tìnding the mots of a generic polynomial to the problem of determining the eigenvalues of tridiagonal matrices having only simple eigenvalues. Since this problem is very effìciently solved, for example with the familiar QR method, it seems that the present veIy simple approach bas the potentiality to supplant the existing ones.

Ultimate Opening (UO) is a powerful operator based on numerical residues. In a multi-scale framework, it analyzes an image under a series of increasing openings. Contrasted objects are detected when they are filtered out by an opening, generating an important residue. Gradual transitions make this operator underestimate the contrast of blurred objects. In this paper we propose a solution to thi...

The flow structure of strongly turbulent Taylor-Couette flow with Reynolds numbers up to Re(i)=2×10(6) of the inner cylinder is experimentally examined with high-speed particle image velocimetry (PIV). The wind Reynolds numbers Re(w) of the turbulent Taylor-vortex flow is found to scale as Re(w)∝Ta(1/2), exactly as predicted by Grossmann and Lohse [Phys. Fluids 23, 045108 (2011).] for the ultim...

A cellular automaton (CA) is a parallel synchronous computing model, which consists in a juxtaposition of finite automata (cells) whose state evolves according to that of their neighbors. Its trace is the set of infinite words representing the sequence of states taken by some particular cell. In this paper we study the ultimate trace of CA and partial CA (a CA restricted to a particular subshif...

Existing statistical ultimate (Frisbee) analyses rely on data aggregates to produce numeric statistics, such as completion percentage and scoring rate, that assess strengths and weaknesses of individuals and teams. We leverage sequential, location-based data to develop completion and scoring maps. These are visual tools that describe the aggregate statistics as a function of location. From thes...

We examine the ultimate fate of individual opinions in a socially interacting population of leftists, centrists and rightists. In an elemental interaction between agents, a centrist and a leftist can both become centrists or both become leftists with equal rates (and similarly for a centrist and a rightist). However leftists and rightists do not interact. This interaction step between pairs of ...

Although a complete nanotechnology does not yet exist, we can already foresee some new directions in theoretical computer science that will be required to help us design maximally efficient computers using nano-scale components. In particular, we can devise novel theoretical models of computation that are intended to faithfully reflect the computational capabilities of physics at the nano-scale...
