This paper describes third aircraft model with 2 degrees of freedom. The aim of this study is to develop a mathematical model for investigation of adoptable landing gear vibration behavior and to design Proportional Integration Derivative (PID) classical techniques for control of active hydraulic nonlinear actuator. The parameters of controller and suspension system are adjusted according to be...

In a well forgotten memoir of 1890, Andrei Markov devised a convergence acceleration technique based on a series transformation which is very similar to what is now known as the WilfZeilberger (WZ) method. We review Markov’s work, put it in the context of modern computeraided WZ machinery, and speculate about possible reasons of the memoir being shelved for so long.

This paper introduces Versat, a minimal Coarse-Grain Reconfigurable Array (CGRA) used as a hardware accelerator to optimize performance and power in a heterogeneous system. Compared to other works, Versat features a smaller number of functional units and a simpler controller. This stems from the observation that competitive acceleration can be achieved with a smaller array and more frequent rec...
