Internationalization of higher education： Challenges, strategies, policies and programs

In today＇s changing world, the idea of internationalization of higher education especially in developing countries has been deduced from globalization of education process. The international aspect of higher education is becoming increasingly important, composite, and confusing. The higher education has an effect on the society through policy-making, funding, and planning. The purpose of this paper is to analyze the meaning, definition, importance, necessity, and pre-requisites of internationalization of higher education. This paper also studies the programs and strategies of internationalization of higher education. Key challenges for the future direction of internationalization are identified in this paper.

Quantitative estimation of dust fall and smoke particles in Quetta Valley

INTRODUCTION Over the recent decades extensive research on atmospheric particles in urban environments was carried out. Most of the following papers refer to their authors’ contribution to air pollution and the effects on human health (Dzubay and Mamane, 1989; van Borm et al., 1989; 1990; Rojas et al., 1990; Paoletti et al., 1991; 1999; Al-Rajhi et al., 1996; McMurry et al., 1996; Querol et al., 1996; BéruBé et al., 1997; Esteve et al., 1997; Harrison et al., 1997; Zou and Hooper…     

Secure distributed Kalman filter using partially homomorphic encryption

In this paper, we present a secure distributed estimation strategy in networked systems. In particular, we consider distributed Kalman filtering as the estimation method and Paillier encryption, which is a partially homomorphic encryption scheme. The proposed strategy protects the confidentiality of the transmitted data within a network. Moreover, it also secures the state estimation computation process. To this end, all the algebraic calculations needed for state estimation in a distributed Kalman filter are performed over the encrypted data. As Paillier encryption only deals with integer data, in general, this, in turn, provides significant quantization error in the computation process associated with the Kalman filter. However, the proposed estimation approach handles quantized data in an efficient way. We provide an optimality and convergence analysis of our proposed method. It is shown that state estimation and a covariance matrix associated with the proposed method remain with a certain small radius of those of a conventional centralized Kalman filter. Simulation results are given to further demonstrate the effectiveness of the proposed scheme.     

Stable model predictive control for a nonlinear system

In this paper, a stable model predictive control approach is proposed for constrained highly nonlinear systems. The technique is a modification of the multistep Newton-type control strategy, which was introduced by Li and Biegler. The proposed control technique is applied on a constrained highly nonlinear aerodynamic test bed, the twin rotor MIMO system (TRMS) to show the efficacy of the control technique. Since the accuracy of the plant model is vital in MPC techniques, the nonlinear state space equations of the system are derived considering all possible effective components. The nonlinear model is adaptively linearized during the prediction horizon. The linearized models of the system are employed to form a linear quadratic objective function subject to a set of inequality constraints due to the system input/output limits. The stability of the control system is guaranteed using the terminal equality constraints technique. The satisfactory performance of the proposed control algorithm on the TRMS validates the effectiveness and the reliability of the approach.
