With the development of machine learning and data mining, rapid design, verification manufacturing have become mainstream in machinery industry. In this paper, mapping function between mechanical properties hood its 11 dimensional parameters was mined using algorithms. By combining XGBoost LightGBM algorithms with bagging method, we proposed a hybrid model hyperparameters optimized by grey wolf...

In this paper, we focus on a packet scheduling algorithm exploiting multiuser diversity in wireless networks. We compare the delay performance of individual user under the scheduling algorithm exploiting multiuser diversity with that under the round-robin scheduling algorithm in order to reveal the characteristics of the scheduling algorithm exploiting multiuser diversity. For this purpose, we ...

In emerging high-speed integrated-services packet-switched networks, fair packet scheduling algorithms in switches and routers will play a critical role in providing the Quality-ofService (QoS) guarantees required by real-time applications. Elastic Round Robin (ERR), a recently proposed scheduling discipline, is very efficient with an O(1) work complexity. In addition, it has superior fairness ...

CPU scheduling is one of the most crucial operations performed by operating system. Different algorithms are available for CPU scheduling amongst them RR (Round Robin) is considered as optimal in time shared environment. The effectiveness of Round Robin completely depends on the choice of time quantum. In this paper a new CPU scheduling algorithm has been proposed, named as DABRR (Dynamic Avera...
