Cognitive radio (CR) is considered as a key enabling technology for dynamic spectrum access to improve spectrum efficiency. Although the CR concept was invented with the core idea of realizing "cognition", the research on measuring CR cognition capabilities and intelligence is largely open. Deriving the intelligence capabilities of CR not only can lead to the development of new CR technologies,...
According to the characteristics of electronic evidence generated by malicious codes, a weighted FP-Growth frequent pattern mining algorithm was proposed for malicious code forensics. Different API call sequences were assigned different weights according to their threaten degree to obtain frequent patterns of serious malicious codes and more accurate analysis results. Based on the weighted FP-Growth...
Xinjiang Uygur's flower hat is famous all over the world, it leads the world of headwear of variou nationalities within China by the variety of styles, the various ways of how to emroider pattern design, and exquisite manufacture. It is unusual even in national costumes art of the world. The poupose of this paper is to analyze Uygur's headwear, study the rules of Uygur's headwear pattern, analyze...
The capacitated arc routing problem (CARP) arises in applications like waste collection or winter gritting. Exact algorithms are still limited to small problems and metaheuristics are required for large scale instances. The paper presents an improved genetic algorithm (GA) for solving an extended version of the CARP (ECARP) like prohibited turns or slop problem. This new algorithm improves the population...
