Basic Algebraic Structures And Field Extensions

open access: yes
U ovom radu proučavali smo osnovne algebarske strukture i kvadratna proširenja polja racionalnih brojeva. Počevši od osnovnih definicija i pojmova iz algebre, istražujemo kako se formiraju proširenja polja, s posebnim naglaskom na kvadratna proširenja ...

Algebraic extensions of difference fields

open access: yes, 1973
An inversive difference field K \mathcal {K} is a field K together with a finite number of automorphisms of K. This paper studies inversive extensions of inversive difference fields whose underlying field extensions are ...

Particle-in-cell based parameter study of 12-cavity, 12-cathode rising-sun relativistic magnetrons for improved performance

open access: yesAIP Advances, 2015
Particle-in-cell simulations are performed to analyze the efficiency, output power and leakage currents in a 12-Cavity, 12-Cathode rising-sun magnetron with diffraction output (MDO).

Combinatorics on Finite Fields: the Sign Repartition for the Quadratic Residues

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014
In the present paper we present the equivalence between the combinatorial determination of the sign repartition for the quadratic residues and non-residues to the computation of the class number of certain quadratic extensions of the field of rationals.

Revisiting Kneser’s theorem for field extensions

open access: yes
A Theorem of Hou, Leung and Xiang generalised Kneser’s addition Theorem to field extensions. This theorem was known to be valid only in separable extensions, and it was a conjecture of Hou that it should be valid for all extensions.

Hidden Markov random field and FRAME modelling for TCA-image analysis [PDF]

open access: yes
Tooth Cementum Annulation (TCA) is an age estimation method carried out on thin cross sections of the root of human teeth. Age is computed by adding the tooth eruption age to the count of annual incremental lines that are called tooth rings and appear in

Theoretical and Experimental Comparison of Efficiency of Finite Field Extensions

open access: yes, 1995
An extension of composite degree over a finite field may be implemented in one or more steps, involving the implementation of zero or more intermediate fields.
