The following problem arises in connection with checking the equivalence piecewise-linear (PL) sets. Consider two-variable polynomials with non-negative integer coe cients, and given two such polynomials, decide if they are equivalent to each other modulo the following equalities x = 2x + 1, y2 = 2y2 + y and y = x + y + 1. In this paper, we show that this problem can be solved in polynomials ti...

Abstract We prove that under the log-Hölder continuity condition of variable exponent $$p(\cdot )$$ p ( · ) , a new type maximal operators, $$U_{\gamma ,s}$$ U γ , s<...

introduction: the major target of this paper shows effect of selected decision variables in the steam system foroptimization of thermal combined cycle power plant.material and method: exergoeconomic, and other similar terms used to imply the combined thermodynamicand economic analysis of energy systems, which helps to increase the efficiency of a plant without jeopardizingits economic viability...

The seat suspension has a significant influence on riding comfort in many practical applications, such as heavy duty vehicles, military and high-speed crafts. This paper proposes equipped with variable equivalent inertance-variable damping (VEI–VD) device novel semi-active vibration control strategy. VEI–VD can its inertance by controlling two external resistors electric circuit. Especially, th...
