ANALYSIS OF POROSITE-NEUTRON (NPHI) LOGGING DATA FROM THE KINKASI FIELD: THE CASE OF THE G UP, F AND E HORIZONS OF THE CENOMANIAN RESERVOIR (D.R. CONGO COASTAL BASIN) [PDF]

open access: yesRomanian Journal of Petroleum & Gas Technology
Since the discovery of hydrocarbon deposits in the DR Congo Coastal Basin in general, and in the Kinkasi field in particular, several development wells have been drilled with a view to optimising the economic value of the reserves evaluated.

On the Saturation of YAGO

open access: yes, 2010
YAGO is an automatically generated ontology out of Wikipedia and WordNet. It is eventually represented in a proprietary flat text file format and a core comprises 10 million facts and formulas. We present a translation of YAGO into the Bernays-Schonfinkel Horn class with equality.

Torque calculation of five-phase synchronous reluctance motors with shifted-asymmetrical-salient-poles under saturation condition

open access: yesCES Transactions on Electrical Machines and Systems, 2020
In traditional analytical method (AM), the magnetic saturation is always ignored to simplify the calculation process. However, synchronous reluctance motors (SynRMs) often operate around saturation point to achieve higher torque density. Therefore, a new

Consensus With Output Saturations [PDF]

open access: yesIEEE Transactions on Automatic Control, 2017
This paper consider a standard consensus algorithm under output saturations. In the presence of output saturations, global consensus can not be realized due to the existence of stable, unachievable equilibrium points for the consensus. Therefore, this paper investigates necessary and sufficient initial conditions for the achievement of consensus, that ...

Numerical Simulation Of The Treatment Of Soil Swelling Using Grid Geocell Columns

open access: yesSlovak Journal of Civil Engineering, 2015
In this paper, a method for the treatment of the swelling of expansive soil is numerically simulated. The method is simply based on the embedment of a geogrid (or a geomesh) in the soil.

On saturation games

open access: yesEuropean Journal of Combinatorics, 2016
A graph $G = (V,E)$ is said to be saturated with respect to a monotone increasing graph property ${\mathcal P}$, if $G \notin {\mathcal P}$ but $G \cup \{e\} \in {\mathcal P}$ for every $e \in \binom{V}{2} \setminus E$. The saturation game $(n, {\mathcal P})$ is played as follows.

Evaluation of Acute Exogenous Hypoxia Impact on the Fraction of Exhaled Nitric Oxide in Healthy Males

open access: yesFolia Medica, 2015
Introduction: Exogenous hypoxia increases ventilation and contracts the pulmonary vessels. Whether those factors change the values of nitric oxide in exhaled air has not yet been evaluated. Objective: To examine the effect of exogenous normobaric hypoxia
