Access control technology protects the cloud from being accessed illegally. However, traditional access control method cannot meet the new demands of the cloud environment. In order to improve the deficiency of the current multi domain access control method in timeliness and flexibility. This paper puts forward a dynamic access control policy on the basis of task driving mechanism. The new meth...

A new Multi-Stage Fuzzy (MSF) controller based on Multi-objective Harmony Search Algorithm (MOHSA) is proposed in this paper to solve the Load Frequency Control (LFC) problem of power systems in deregulated environment. LFC problem are caused by load perturbations, which continuously disturb the normal operation of power system. The objectives of LFC are to mini small size the transient deviati...

A randomized controlled trial (RCT) is used to study the safety and efficacy of new treatments, by comparing patient outcomes an intervention group with a control group. Traditionally, RCTs rely on statistical analyses assess differences between treatment groups. However, such are generally not designed impact at individual level. In this paper, we explore machine learning models in conjunction...

In this paper we present a decentralized gradient-based controller that optimizes communication between mobile aerial vehicles and stationary ground sensor vehicles in an environment with infeasible regions. The formulation of our problem as a MIQP is easily implementable, and we show that the addition of a scaling matrix can improve the range of attainable converged solutions by influencing tr...
