A simple statistical approach based on exponentially weighted moving average (EWMA) charts for monitoring quality of service (QoS) violations is presented in this paper. The monitoring is performed by checking the actual services performance against the QoS stated in Service Level Agreement (SLA). Our approach monitors their QoS attributes and reveals early forecasts of violations in customers' demands...
This study attempts to upgrade the service efficiencies of cloud management by proposing different quality approaches. We design two detecting mechanisms to search the early violation signal by a different quality level of confidence. This research attempts to prevent assignable variables existed in violation situations. We proposed and verified the Moving Range Chart and EWMA Chart by utilizing CLOUDSIM...
In green management, the quality control performs a key factor for chain materials and products in chain productions. Selecting the correct control chart is essential to effectively monitoring process shifts. In particularly, a nonparametric control chart is recommended over a traditional control chart when the quality characteristics of a process are unknown. This paper designs an intelligent genetic...
In order to improve the quality and efficiency of ground-to-air data communication, the improved two dimension markov model is put forward. Then the best Rth improved arithmetic, the best Fth improved arithmetic and the mixed best threshold arithmetic which introduces two mechanism are discussed, and the method is given. The new method provides theory idea for dispeling network performance paremeter...
In this paper, we present a low-cost airborne radar target simulator based on FPGA, which consists of three parts: control and video processing module, intermediate frequency (IF) processing module and radio frequency (RF) processing module. The system is capable of simulating target echoes with range, Doppler, direction and the other information in real time. We also elaborate the highlights of design...
