On the J-Tightness of Graphs

Abolfazl Javan; Majid Javan; M. Jafarpour; Dara Moazzami; Ali Moieni

Volume 53, Issue 2 , December 2021, , Pages 57-74

Abstract
  We introduce a new invariant vulnerability parameter named “J-Tightness” or “J(G)” for graphs. As a stability measure, its properties along with comparisons to other parameters of a graph are proposed. We show how it is calculated for complete graphs and cycles. We show that J-Tightness ...  Read More

Implementation of Combinational Logic Circuits Using Nearest-Neighbor One-Dimensional Four-State Cellular Automata

Abolfazl Javan; Maryam Jafarpour; Ali Moieni; Mohammad Shekaramiz

Volume 52, Issue 2 , December 2020, , Pages 41-56

https://doi.org/10.22059/jac.2020.79225

Abstract
  Cellular automata are simple mathematical idealizations of natural systems. They consist of a lattice of discrete identical sites, each site taking on a finite set of, say, integer values. Over the years, scientists have been trying to investigate the computational capabilities of cellular automata by ...  Read More

Solving a non-linear optimization problem in the presence of Yager-FRE constraints

A. Ghodousian; Abolfazl Javan; Asieh Khoshnood

Volume 50, Issue 1 , June 2018, , Pages 155-183

https://doi.org/10.22059/jac.2018.68964

Abstract
  Yager family of t-norms is a parametric family of continuous nilpotent t-norms which is also one of the most frequently applied one. This family of t-norms is strictly increasing in its parameter and covers the whole spectrum of t-norms when the parameter is changed from zero to infinity. In this paper, ...  Read More

Normalized Tenacity and Normalized Toughness of Graphs

A. Javan; M. Jafarpour; D. Moazzami; A. Moieni

Volume 49, Issue 2 , December 2017, , Pages 141-159

https://doi.org/10.22059/jac.2017.67083

Abstract
  In this paper, we introduce the novel parameters indicating Normalized Tenacity ($T_N$) and Normalized Toughness ($t_N$) by a modification on existing Tenacity and Toughness parameters.  Using these new parameters enables the graphs with different orders be comparable with each other regarding their ...  Read More
