the analysis of the role of the speech acts theory in translating and dubbing hollywood films
از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
15 صفحه اولClifford Algebra and Dirac equation for TE, TM in waveguide
Following Hestenes and others we explore the possibility that the electron is a (sort of) bound electromagnetic wave. To do this a waveguide analogy is considered. The E, H field components in waveguide satisfy the second order Klein Gordon equation. The question is if a (first order) Dirac equation is involved. Making use of Clifford Algebra, by first it is shown that a spinor ψ satisfying Dir...
متن کاملOn the equivalence of Daviau’s space Clifford algebraic, Hestenes’ and Parra’s formulations of (real) Dirac theory
Recently Daviau showed the equivalence of ordinary matrix based Dirac theory –formulated within a spinor bundle Sx ≃ C 4 x–, to a Clifford algebraic formulation within space Clifford algebra Cl(R, δ) ≃ M2(C) ≃ P ≃ Pauli algebra (matrices) ≃ H ⊕ H ≃ biquaternions. We will show, that Daviau’s map θ : C 7→ M2(C) is an isomorphism. Furthermore it is shown that Hestenes’ and Parra’s formulations are...
متن کاملThe Dirac Algebra and its Physical Interpretation
A version of the Dirac equation is derived from first principles using a combination of quaternions and multivariate 4-vectors. The nilpotent form of the operators used allows us to derive explicit expressions for the wavefunctions of free fermions, vector bosons, scalar bosons, Bose-Einstein condensates, and baryons; annihilation, creation and vacuum operators; the quantum field integrals; and...
متن کاملUse of group theory and Clifford algebra in the study of generalized Dirac equation for particles with arbitrary spin
contains many of the features of the Dirac theory. The theory of spin-s free particles has been also developed by Proca [4], Kemmer [5] and Bargmann and Wigner [6]. All of these formalisms for spin-s free particles have many intrinsic contradictions and difficulties when an electromagnetic field interaction is introduced (see [7] and references therein). It should be noted that the mathematical...
