In this paper, the controllability of differential systems with general conformable derivative is studied. By elaborating rank criterion and Gram criterion, sufficient necessary conditions to investigate that a linear system null completely controllable are given. We obtain full generalization fractional-order case. addition, Krasnoselskii’s fixed point theorem complete result for semilinear ap...

Lateral velocity has very backbone position in the railway vehicle wheelset dynamics as it usually becomes cause of derailment by sliding due to insufficient adhesion ratio. This impropriate balance is pretext owing to contamination and weather procures the disturbances. This perturbation makes hindrances in proper running of wheelset on track. To analyze the noise, Kalman filter is used based ...

In this paper, a double balanced radio frequency multiplier is presented which is customized for transmitted reference ultra wideband (UWB) receivers. The multiplier uses 90nm model parameters and exploits compensating transistors to provide controllable gain for a Gilbert core. After performing periodic and quasiperiodic non linear analyses the RF mixer (multiplier) achieves a voltage conversi...

Hydrodynamic and aerodynamic lubrication regimes in their controllable forms have been intensively investigated over the last two decades. With the aim of reducing friction and improving thermal, static, and dynamic characteristics of radial sliding bearings, different types of electro-mechanical actuators have been coupled to such bearings. Depending on (i) the actuator type; (ii) the actuatio...

In this article, we study some existence and controllability results for two classes of second order functional differential equations with delay random effects. To begin, employ a fixed point theorem stochastic domain to demonstrate the mild solutions. Next, prove that our problems are controllable. Finally, an example is given validate theory part.

In this paper, a new method is proposed to optimize a multi-response optimization problem based on the Taguchi method for the processes where controllable factors are the smaller-the-better (STB)-type variables and the analyzer desires to find an optimal solution with smaller amount of controllable factors. In such processes, the overall output quality of the product should be maximized while t...
