Integrating Hasse-Schmidt derivations [PDF]

open access: yes, 2014
We study integrating (that is expanding to a Hasse-Schmidt derivation) derivations, and more generally truncated Hasse-Schmidt derivations, satisfying iterativity conditions given by formal group laws.

Compressible primitive equation: formal derivation and stability of weak solutions [PDF]

open access: yes, 2010
We present a formal derivation of a simplified version of Compressible Primitive Equations (CPEs) for atmosphere modeling. They are obtained from $3$-D compressible Navier-Stokes equations with an \emph{anisotropic viscous stress tensor} where viscosity ...

Some consequence relations on propositional formulas [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2011
Consequence relations on propositional formulas are binary relations on propositional formulas that represent certain types of entailment - formal or semi-formal derivation of conclusion from a certain set of premises.

Higher Derivatives and Canonical Formalisms [PDF]

open access: yesProgress of Theoretical Physics, 1996
Path integral expressions for three canonical formalisms -- Ostrogradski's one, constrained one and generalized one -- of higher-derivative theories are given. For each fomalism we consider both nonsingular and singular cases. It is shown that three formalisms share the same path integral expressions. In paticular it is pointed out that the generalized

On the Origin of Model Relations among Transverse-Momentum Dependent Parton Distributions [PDF]

open access: yes, 2011
Transverse-momentum dependent parton distributions (TMDs) are studied in the framework of quark models. In particular, quark-model relations among TMDs are reviewed, elucidating their physical origin in terms of the quark-spin structure in the nucleon ...

Final State Interactions in Kaon Decays [PDF]

open access: yes, 2000
We quantify the important effect of strong final state interactions in the weak $K\to 2\pi$ amplitudes, using the measured $\pi$-$\pi$ phase shifts with J=0 and $I=0,2$.

La derivación verbal apreciativa en español

open access: yesEstudios de Lingüística, 1998
This paper analyzes the verb formation by means of the called, in Spanish, affixal «apreciativos». The paper is split into three subparts that are occupied by others so man y facets of this type of derivation.

General Approach for the Sensitivity Analysis and Optimization of Integrated Optical Evanescent-Wave Sensors [PDF]

open access: yes, 2014
The optimization of integrated optical evanescent-wave sensors is dual. For optimal performances, we require waveguides with both maximal sensitivity to the measurand, the quantity intended to be measured, and minimal sensitivities to perturbations.

Higher Derivative Gravity in Generalized Covariant Derivative Formalism [PDF]

open access: yesProgress of Theoretical Physics, 1999
Field strength (‘curvature’ tensor in mathematical terms) is one of the key concepts in gauge theory. To develop a new unified theory of the gauge and Higgs fields, a “field strength” is introduced for the Higgs field by generalizing covariant derivatives for chiral multi-spinor fields so as to include the Dirac γ-matrices.

A Petri Net Strategy for Fault Diagnosis and Location in Power Distribution Systems to Prevent Local Power Shortages

open access: yesIEEE Access
A power distribution system is usually composed of a number of distribution substations and distribution lines, where the latter are fragile and often suffer from faults, leading to serious local power shortages.
