Very well-drained lands could have a positive impact in various soil health indicators such as erosion and texture. A drainage system is responsible for properly aerated soil. Until today, order to design system, big challenge remained find the subsurface drain spacing because many of hydraulic parameters present significant uncertainties. This fact also creates uncertainties overall physical p...

Recent years have seen a rise in state-sponsored malware. Advanced Persistent Threat groups (APTs) been waging covert war with little repercussions due to the clandestine nature of cyberconflict. For sanctions be imposed, malware attribution is an important stage attack analysis because exploitation known vulnerabilities via execution one methods APT attackers use establish foothold target’s ne...

This work aims to improve simulation performance by introducing fuzzy logic in the discrete event simulation. This paper attempts to develop a new approach to assess the duration of dynamical systems, especially the natural processes. To do, we have used the fuzzy logic theory and particularly the fuzzy inference system combined to the discrete event simulation (DEVS). The process simulation is...

Fuzzy set theory opens new vistas in computability theory and here I show this by defining a new computational metaphor—the fuzzy chemical metaphor. This metaphor is an extension of the chemical metaphor. In particular, I introduce the idea of a state of a system as a solution of fuzzy molecules, that is molecules that are not just different but rather similar, that react according to a set of ...

This paper presents a new observer based fuzzy terminal sliding mode controller design for a class of fractional order nonlinear systems. Robustness against uncertainty and disturbance, the stability of the close loop system and the convergence of both the tracking and observer errors to zero are the merits of the proposed the observer and the controller. The high gain observer is applied to es...

For reducing the steady state speed ripple, especially in high performance speed servo system applications, the steady state precision is more and more important for real servo systems. This paper investigates the steady state speed ripple periodic disturbance problem for a permanent magnet synchronous motor (PMSM) servo system; a fuzzy adaptive repetitive controller is designed in the speed lo...
