Dört boyutlu Ising modelinin, dorusal boyutu L =4,6,8,10,12,14,16 olan periyodik sınır artlı soyut basit küp örgülerde, dört “bit”li demonlar kullanılarak Creutz cellular automaton’ında simülasyonu yapıldı. Simülasyondan elde edilen veriler bilinen sonlu örgü ölçekleme teorisi ve logaritmik düzeltmeli sonlu örgü ölçekleme teorisine göre analiz edildi. Manyetik alınganlık için kritik üs logaritmik düzeltme olmaksızın ν γ = 2.2529 logaritmik düzeltmeli ν γ = 2.0057, özısı için kritik üs logaritmik düzeltme olmaksızın α ν = -0.0715 logaritmik düzeltmeli α ν = 0.0932 α ν = -0.1055 elde edildi. Bu sonuçlar üç “bit”li demonlar kullanılarak yapılan simülasyon sonuçları ve teorik deerlerle uyum halindedir.
The four-dimensional nearest-neighbor Ising model is simulated on the Creutz cellular automaton by using four-bit demons and the finite-size lattices with the linear dimension L=4,6,8,10,12,14,16. The simulation results for the finite-lattice are analyzed according to the conventional finite-size scaling theory with and without logarithmic factors. Critical exponents of the magnetic susceptibility ( χ ) is found as = .2 0057 ν γ when the expression with the logarithmic factor is used and as = .2 2529 ν γ when the expression without logarithmic factor is used. Similarity, the exponents for the specific heat (C ) are calculated as = .0 0932 ν α , = − .0 1055 ν α with the logarithmic factor and = − .0 0715 ν α without logaritmic factor.These results are in good agreement with the results of simulations with three-bit demons and theoretical values.

Selcuk University Journal of Science Faculty accepts articles in Turkish and English with original results in basic sciences and other applied sciences. The journal may also include compilations containing current innovations.
It was first published in 1981 as "S.Ü. Fen-Edebiyat Fakültesi Dergisi" and was published under this name until 1984 (Number 1-4).
In 1984, its name was changed to "S.Ü. Fen-Edeb. Fak. Fen Dergisi" and it was published under this name as of the 5th issue.
When the Faculty of Letters and Sciences was separated into the Faculty of Science and the Faculty of Letters with the decision of the Council of Ministers numbered 2008/4344 published in the Official Gazette dated 3 December 2008 and numbered 27073, it has been published as "Selcuk University Journal of Science Faculty" since 2009.
It has been scanned in DergiPark since 2016.
