Effect of the oxygen minimum zone on the second chlorophyll maximum

open access: yesCiencias Marinas, 2009
Field data collected during June 2005 were used to determine the relationship between the second fluorescence maximum (FMax), the top of the oxygen minimum zone (OMZ), and physical processes (coastal currents, eddies, and upwelling) in the northern ...

Strict Fejér Monotonicity by Superiorization of Feasibility-Seeking Projection Methods [PDF]

open access: yesarXiv, 2014
We consider the superiorization methodology, which can be thought of as lying between feasibility-seeking and constrained minimization. It is not quite trying to solve the full fledged constrained minimization problem; rather, the task is to find a feasible point which is superior (with respect to the objective function value) to one returned by a ...

Superiorization of Preconditioned Conjugate Gradient Algorithms for Tomographic Image Reconstruction [PDF]

open access: yesarXiv, 2018
Properties of Superiorized Preconditioned Conjugate Gradient (SupPCG) algorithms in image reconstruction from projections are examined. Least squares (LS) is usually chosen for measuring data-inconsistency in these inverse problems. Preconditioned Conjugate Gradient algorithms are fast methods for finding an LS solution. However, for ill-posed problems,

Lanthanum-Cerium Based Bulk Metallic Glasses with Superior Glass-Forming Ability [PDF]

open access: yesarXiv, 2006
A quinary (La0.5Ce0.5)65Al10(Co0.6Cu0.4)25 alloy with superior glass-forming ability (GFA), identified by the formation of fully glassy rod of 32 mm in diameter by tilt-pour casting, was reported. By comparing with the GFA of quarternary (La0.5Ce0.5)65Al10TM25 and ternary Ln65Al10TM25 alloys (Ln = La or Ce; TM = Co or Cu), we suggest that the strong ...

Jet Geometrical Objects Produced by Linear ODEs Systems and Superior Order ODEs [PDF]

open access: yesStudia Universitatis Babes-Bolyai Mathematica, Vol. LVI, No. 1 (2011), 85-99, 2007
The aim of this paper is to construct a Riemann-Lagrange geometry on 1-jet spaces, in the sense of d-connections, d-torsions, d-curvatures, electromagnetic d-field and geometric electromagnetic Yang-Mills energy, starting from a given linear ODEs system or a given superior order ODE.
