Due to asynchronous packet transmissions and rate mismatch among different coding flows in existing opportunistic network coding architectures, such as COPE, the amount of packets which can be coded together may be insufficient and thus the performance gain of network coding cannot be fully exploited. One feasible solution for this problem is to make coding nodepurposely delay some packet transmissions...
This paper presents a method to describe nonlinear oscillation of power system. Specifically, this paper uses the con trolling mode which is identified by the extended equal-area criterion (EEAC). The energy of center equal point (CEP) or far end point (FEP) in each swing is used to express the oscillation energy of the controlling mode, so the trend of swing energy variations can be used to show...
Person re-identification has been widely studied due to its importance in surveillance and forensics applications. In practice, gallery images are high-resolution (HR) while probe images are usually low-resolution (LR) in the identification scenarios with large variation of illumination, weather or quality of cameras. Person re-identification in this kind of scenarios, which we call super-resolution...
Existing network coding architectures such as COPE in wireless networks depend on opportunistic listening to improve network throughput. Data cache management for the purpose of decoding to enhance the performance gain of network coding has not been deeply investigated. In this paper, we present a general model to address this problem, aiming at improving decoding efficiency of network coding and...
Existing opportunistic network coding architectures relies on pseudobroadcast to deliver a coded packet to multiple receivers in a single transmission. In such situation, there is only one primary receiver who acknowledges the reception by synchronous MAC-layer acknowledgements (ACKs) and the other receivers receive it by overhearing and acknowledge the reception by asynchronous ACKs, which are usually...
In existing opportunistic network coding architectures, such as COPE, due to asynchronous packet transmissions and rate mismatch, the amount of packets which can be coded together may be insufficient. This may limit the performance gain of network coding. Purposely delaying some packet transmissions to accumulate more coding opportunities could be a feasible solution to this problem. However, excessive...
The theory of all-round development of human beings is an important component of Marxism system, and is also the theoretical basis of human resources management for colleges. The key to the personnel system reform of colleges should, on the basis of all-round development of human beings of Marxism and on the precondition of fully carrying out the scientific outlook on development, make human resources...
According to engineering geological conditions of one certain coal mine, YF20-3 fault of the mine is without water and not leading water by detection and analysis. In order to make full utilization of coal resources, fault pillar is optimized with FLAC3D software in this paper. Based on numerical simulation of fault pillar optimization in fully mechanized caving face, we analyzed dynamic failure mechanism...
