A Traffic Light Recognition Algorithm Based On Compressive Tracking
Xuanru Zhou,Jiazheng Yuan,Hongzhe Liu 보안공학연구지원센터 2015 International Journal of Hybrid Information Techno Vol.8 No.6
According to the traffic light recognition problem of intelligent vehicle, this paper proposes a traffic light recognition algorithm based on compressive tracking. First, the candidate regions of traffic light are extracted. Second, after extracting the HOG feature of candidate regions, using the machine learning for classification and recognition, compressive tracking algorithm is used to track lights that have been identified a automatically. This algorithm combines feature recognition and tracking identification of traffic light and traffic light changes in scale and color can be identified normally. The algorithm proposed in this paper has been tested on actual road in intelligent vehicle; traffic light recognition effect is good.
Energy Aware Scheduling based on Two-phase Frequency Scaling for Parallel Tasks in Cluster
Aihua Liang,Jun Liang,Jiazheng Yuan 보안공학연구지원센터 2015 International Journal of Grid and Distributed Comp Vol.8 No.5
Improving the energy efficiency of high performance clusters has become important research issue. We proposed a new algorithm that reduces energy consumption of precedence constrained parallel tasks in power-scalable clusters. To reduce energy consumption without increasing the schedule length, our algorithm reclaims both static and dynamic slack time and employs different frequency adjusting techniques in different slack time. The optimal frequency is obtained through analyzing the precedence constraints of parallel tasks. We conducted extensive experiments to compare the proposed algorithm with two other existing algorithms, simulation results show that the proposed algorithm can get better energy efficiency without increasing the make span.

(±)-Decumicorine A ( 1 ) and (±)- epi -decumicorine A ( 2 ), two pairs of enantiomeric isoquinoline alkaloids featuring a novel phenylpropanoid-conjugated protoberberine skeleton, were isolated and purifi ed from the rhizomes of Corydalis decumbens . The separation of (±)- 1 and (±)- 2 was achieved by chiral HPLC to produce four optically pure enantiomers. The structures and absolute confi gurations of compounds (−)- 1 , (+)- 1 , (−)- 2 , and (+)- 2 were elucidated by spectroscopic analysis, ECD calculations, and X-ray crystallographic analyses. The two racemates were generated from a Diels-Alder [4 + 2] cycloaddition between jatrorrhizine and ferulic acid in the proposed biosynthetic pathways, which were fully verifi ed by a biomimetic synthesis. Moreover, compound (+)- 1 exhibited an antiviral entry eff ect on SARS-CoV-2 pseudovirus by blocking spike binding to the ACE2 receptor on HEK-293T-ACE2 h host cells.
