In this paper, a semi-empirical multiple-input multiple-output (MIMO) channel model is proposed for highspeed railway (HSR) viaduct scenarios. The proposed MIMO model is based on single-input single-output (SISO) wideband channel measurements under a viaduct on Zhengzhou-Xi'an HSR in China and a geometry-based stochastic model (GBSM) composed of a one-ring model and an elliptical model. Environment-related...
Carrier Aggregation (CA) is one of the important technologies to further improve the capacity of Long Term Evolution Advanced (LTE-A). When CA is conducted, a User Equipment (UE) will firstly select a Primary Serving Cell (PCell) for mobility support and then add Secondary Serving Cells (SCell) for higher experienced data rate. When and how to add/remove SCell is a very important issue, especially...
Originated in the 1970s, the theory of competence has become today's leading issue in the field of management and psychology. The current research interviewed 20 provincial grade and higher sports coaches relating to 8 sports events using the Behavior Events Interview (BEI) in Sichuan province, after which ldquoThe Competency Dictionary of Sports Coaches of Chinardquo was utilized to rate/code the...
Technological advancements in communication and embedded computing lead to the increasing application of decentralized structures in automation and control. The decentralization adds new behavior in the form of - often non-deterministic - delays to the resulting networked control systems (NCS). To analyze a closed loop control system including network communication, simulation is a viable approach...
In this paper we propose a component-based analytical performance model for IP-SAN. We model four key components within IP-SAN individually and they are IP network, cache, RAID and disks. We validate these component models and compose them to give an entire IP-SAN performance model. The entire IP-SAN model analyzes the performance of an IP-SAN configuration under multiple synchronous workloads by...
