Video telephony has recently gained its momentum and is widely adopted by end-consumers. But there have been very few studies on the network impacts of video calls and the user Quality-of-Experience (QoE) under different network conditions. In this paper, we study the rate control and video quality of Skype video calls. We first measure the behaviors of Skype video calls on a controlled network testbed...
This paper mainly introduces the use of 1∶10000 magnetic measurement data for geological structure Huailai area and its interpretation. Through the region to deal with the geomagnetic data, the method further summarized the conditions and sign the application. In the data processing, the use of Surfer8.0 software grid for data preprocessing. Use of conventional gravity and magnetic data processing...
To uncertain linear neutral systems with time-invariant lumped delays, this paper introduces a method of designing state feedback H∞ reliable controller with actuator mixed fault model of actuator failures, in terms of LMI, and gives a sufficient condition which satisfies that reliable H∞ norm non-exceed a specified positive number. A reliable H∞ controller will be given via solving LMI. A numerical...
As Modern Service Industry (MSI) improves with economic restructuring in China, emerging user-central applications bring enormous challenges to current communication networks characterized with heterogeneity. In this paper, an advanced mobility management architecture with three main function modules in the next generation heterogeneous network (NGHN), is presented to support personal mobility and...
Next generation communication will offer a wide range of services available to users anywhere at any time, which needs the heterogeneous network to support. Enabling users access service resource effectively across heterogeneous network enhance the users experience. This paper presents an intelligent handover control model based on selection strategy for aiding users handover in this'one user with...
Given a set of connecting nodes in a signal net on different layers for 3D ICs, based on the concept of hidden Steiner-point assignment on the same layer or different layers, a merging-based approach is proposed to construct a timing-driven 3D rectilinear Steiner tree. Compared with a spanning-tree-based approach, the experimental results show that our proposed approach has 9.7%~16% improvement in...
