Integrating UML and Formal Methods

open access: yesElectronic Notes in Theoretical Computer Science, 2007
AbstractUML is a widespread language used in both industry and academia, despite the fact that its semantics is still informal and allows ambiguities. On the other hand, OhCircus is a formal specification language which unifies Z, CSP, the refinement calculus of Morgan and object-oriented theories.

Investigating the Integration of two Formal Methods [PDF]

open access: yesFormal Aspects of Computing, 1998
Abstract. VDM and B are two mature formal methods currently in use by industry and supported by commercial tools. Though the methods are foundationally similar, the coverage of their supporting tools differ significantly. The SPECTRUM project has investigated the feasibility of integrating support for the two methodologies.

A commutative noncommutative fractal geometry [PDF]

open access: yes, 2011
In this thesis examples of spectral triples, which represent fractal sets, are examined and new insights into their noncommutative geometries are obtained.

Path integral formalism for the free Dirac propagator in spherical coordinates [PDF]

open access: yes, 2023
The relativistic Green's function of a free spin-1/2 fermion is derived using the Feynman path integral formalism in spherical coordinates. The Green's function is reduced to an exactly solvable path integral by an appropriate coordinate transformation ...

N-photon amplitudes in a plane-wave background

open access: yesPhysics Letters B, 2021
We use the worldline formalism to derive master formulas for the one-loop N-photon amplitudes in a plane-wave background, for both scalar and spinor quantum electrodynamics.

Line Defects in Two-Dimensional Dodecagonal Quasicrystals

open access: yesMathematics
In this work, line defects in two-dimensional dodecagonal quasicrystals are investigated. Using the ten-dimensional framework of the integral formalism of two-dimensional quasicrystals, the closed-form solutions for the displacement fields and stress ...

On the reliability of residual stress measurements in unidirectional carbon fibre reinforced epoxy composites

open access: yesPolymer Testing, 2021
The present work introduces a novel methodology to analyse non-uniform residual stresses in composite materials. For robust determination of stresses in complex structures made of different layers, it is first necessary to prove that residual stress ...

A gauge-invariant path integral for electrodynamics with magnetic monopoles in the Haddamard formalism [PDF]

open access: yes, 2017
We propose a new path integral for QED in the presence of magnetic monopoles on the formalism of Geometric Algebra of Hestenes–Haddamard written in terms of Dirac matrices.

Quantum sampling for the Euclidean path integral of lattice gauge theory [PDF]

open access: yes, 2022
Although the Hamiltonian formalism is so far favored for quantum computation of lattice gauge theory, the path integral formalism would never be useless.
