Cohn called a ring $R$ is reversible if whenever $ab = 0,$ then $ba = 0$ for $a,bin R.$ The reversible property is an important role in noncommutative ring theory‎. ‎Recently‎, ‎Abdul-Jabbar et al‎. ‎studied the reversible ring property on nilpotent elements‎, ‎introducing‎ the concept of commutativity of nilpotent elements at zero (simply‎, ‎a CNZ ring)‎. ‎In this paper‎, ‎we extend the CNZ pr...

as a distinct socially constructed genre, wedding invitations (wis) offer a fruitful site for investigating how two areas of genre knowledge (i.e., form and content) change over time under the influence of sociocultural forces. through the examination of 100 iranian wis dating from 1970s to the present time, the study investigated the trajectories of change through time within the social semiot...

This paper proposes creating new reversible marking technique. This originally based on indentifying parts of the image which are watermarked using two different Histogram Shifting (HS) modulations. One is Pixel Histogram shifting and other is Dynamic Prediction Error Histogram Shifting (DPEHS). This technique offers a very good compromise in terms of capacity and image quality preservation for...

In this paper a smooth control algorithm for gear shifting is proposed for improving longitudinal dynamic performance during dry dual-clutch engagements while shifting up or down takes place based on measurements of engine speed and clutch speed, and on estimation of the dual-clutch engaging torque. Simulation effort is made by Matlab/Simulink for transient responses of the overall propulsion s...
