Frequent-pattern mining is a common means to reveal the hidden trends behind data. However, most frequent-pattern mining algorithms are designed for DRAM, instead of the energy-economic nonvolatile memories (NVMs). Due to the huge differences between the characteristics of NVMs and those of DRAM, existing frequent-pattern mining algorithms suffer from serious overheads of write amplification or energy...
Ultra-dense networks (UDNs), which can provide extremely high throughput and data rates, have been considered as one of the key techniques for the fifth generation mobile networks. However, it may cause severe inter-cell interference and significant energy consumption due to numerous base stations (BSs) being randomly deployed. To mitigate the interference and boost energy efficiency (EE) of the UDN...
To analyze the multi-failure under incomplete information condition, the model based on concept lattice is constructed according to the binary relation between failure modes and basic function elements. Aiming at solving the problem caused by the incomplete information, the algorithm based on maximal confidence, function elements value expectation is designed, develop the extended discernibility matrix...
Random decision trees algorithm, which is no need to count images and has good portability, is a great prospective method for land cover remote sensing classification at present. An improved random decision trees algorithm with application to land cover remote sensing classification was proposed in this paper. Firstly, in accordance with the low operation efficiency of random decision trees algorithm,...
There are not enough algorithms for line clipping against concave polygon, linear time algorithm against concave polygon even does not exist. This paper presents a linear time algorithm for the line clipping against concave polygon (including concave polygon with a hole inside). Line segment was represented by parametric representation; firstly, calculate the intersection point (represented by parameter...
Topology control for maximizing network capacity for the practical power-fixed IEEE 802.11-based ad hoc networks is deeply investigated in this paper. Several interference-model-based algorithms have been proposed to maximize network capacity through reducing interference during recent years. However, most of those algorithms are based on node location and not practical in IEEE 802.11-based ad hoc...
Small and medium sized enterprises (SMEs) have been playing more and more important roles in modern economy. However, only a little attention has been paid to the SME oriented supply chain management research. Purchasing is one of the most important components of supply chain management. To profit from cooperative purchasing, this paper proposes a SME oriented multi-agent system (MAS), which constructs...
