Uncertain switched linear systems are known as an important class of control systems. Performance of these systems is affected by uncertainties and its stabilization is a main concern of recent studies. Existing work on stabilization of these systems only provides asymptotical stabilization via designing switching strategy and state-feedback controller. In this paper, a new switching strate...

  This study investigated the effect of gender and type of written corrective feedback (WCF) on Iranian pre-intermediate EFL learners’ writing. Four intact classes were assigned to experimental and two intact classes to control groups. The learners were homogenized using a pre-test which was followed by sixteen sessions lasting one hour and forty five minutes. After receiving instruction on how...

Bitcoin derivatives positions are maintained with a self-selected margin, which is often too low to avoid automatic liquidation by the exchange, without notice, especially during periods of excessive volatility. Indeed, according CryptoQuant, almost $80 billion on centralised exchanges were liquidated 2021, that an average over $200 million per day. So hedgers bitcoin price risk should account ...

We isolate a U.S. dollar currency premium by comparing corporate bonds issued in the and euro firms o utside t he U .S. nd e uro rea. make s everal empirical observations that dissect perceived advantage of borrowing dollar. First, while dominates global debt issuance, costs are more expensive without hedge about same with when compared to euro. This observed parity currency-hedged stands contr...

In this paper a new nonlinear guidance law with finite time convergence is proposed. The second order integrated guidance and control loop is formulated considering a first order control loop dynamics. By transforming the state equations to the normal form, a finite time stabilizer feedback linearization technique is proposed to guarantee the finite time convergence of the system states to zero...

In this paper, it is shown that by exploiting the explicit parametric state feedback solution, it is feasible to obtain the ultimate solution to minimum sensitivity problem. A numerical algorithm for construction of a robust state feedback in eigenvalue assignment problem for a controllable linear system is presented. By using a generalized parametric vector companion form, the problem of eigen...
