Hybrid CSA optimization with seasonal RVR in traffic flow forecasting
( Zhangguo Shen ),( Wanliang Wang ),( Qing Shen ),( Zechao Li ) 한국인터넷정보학회 2017 KSII Transactions on Internet and Information Syst Vol.11 No.10
Accurate traffic flow forecasting is critical to the development and implementation of city intelligent transportation systems. Therefore, it is one of the most important components in the research of urban traffic scheduling. However, traffic flow forecasting involves a rather complex nonlinear data pattern, particularly during workday peak periods, and a lot of research has shown that traffic flow data reveals a seasonal trend. This paper proposes a new traffic flow forecasting model that combines seasonal relevance vector regression with the hybrid chaotic simulated annealing method (SRVRCSA). Additionally, a numerical example of traffic flow data from The Transportation Data Research Laboratory is used to elucidate the forecasting performance of the proposed SRVRCSA model. The forecasting results indicate that the proposed model yields more accurate forecasting results than the seasonal auto regressive integrated moving average (SARIMA), the double seasonal Holt-Winters exponential smoothing (DSHWES), and the relevance vector regression with hybrid Chaotic Simulated Annealing method (RVRCSA) models. The forecasting performance of RVRCSA with different kernel functions is also studied.

The objective of this study was to get a comprehensive understanding of how genes in chicken shell gland modulate eggshell strength at the early stage of active calcification. Four 32-week old of purebred Xianju hens with consistent high or low shell breakage strength were grouped into two pairs. Using Affymetrix Chicken Array, a whole-transcriptome analysis was performed on hen's shell gland at 9 h post oviposition. Gene ontology enrichment analysis for differentially expressed (DE) transcripts was performed using the web-based GOEAST, and the validation of DE-transcripts was tested by qRT-PCR. 1,195 DE-transcripts, corresponding to 941 unique genes were identified in hens with strong eggshell compared to weak shell hens. According to gene ontology annotations, there are 77 DE-transcripts encoding ion transporters and secreted extracellular matrix proteins, and at least 26 DE-transcripts related to carbohydrate metabolism or post-translation glycosylation modification; furthermore, there are 88 signaling DE-transcripts. GO term enrichment analysis suggests that some DE-transcripts mediate reproductive hormones or neurotransmitters to affect eggshell quality through a complex suite of biophysical processes. These results reveal some candidate genes involved with eggshell strength at the early stage of active calcification which may facilitate our understanding of regulating mechanisms of eggshell quality.

In this paper, by means of adding nonsuperconductive phase silver into YBCO matrix, the superconductivity of Melted Texture Growth(MTG) YBaCuO was improved remarkably. In order to eliminate the crack in the YBCO and the weak link in the grain boundary, Ag contents from 2wt% to 18wt% were doped in the YBCO. It was found that Jc of YBCO increases with the increasing Ag content till 14wt%, over 14wt% of Ag contenr, the Jc tends to stable. The grain size of YBCO became fine when Ag was added in the YBCO and X-ray diffraction showed that the YBCO crystal prepared by the above technique had (001) oriention and growing plane of YBCO was a-b plane. Using Bean´s medel, the Jc was calculated and the best result was Jc = 76000 A/cm²(77K, 100Gs).

Water Caves of Liaoning in Northeastern China -Shenyang Water Cave and Benxi Water Cave-
( Dea Wha Soh ),( Zhangguo Fan ) 한국동굴학회 2004 동굴 Vol.65 No.-
To introduce the typical water caves of the northeastern district in China, the Shenyang Water Cave located in the Shenyang city and the Benxi Water Cave located in the Benxi city of the Liaoning province of the northeastern part of China are presented. The caves are very big and long, and the water flows in the cave to drive the motor boat for tourist watching the beautiful sight in the caves through the year. The geological information and the beautiful internal sight of views in the caves are introduced.

In this paper, a master-slave control system is proposed and applied in an intention-actuated exoskeletal robot to assist user locomotion and lower extremity rehabilitation simultaneously. In particular, to increase users’ sense of participation, the motion of the exoskeleton and the wheelchair, which is denoted as slave motion in this study, is actuated by the user’s intention, which is denoted as master motion and thus makes patients feel that they are moving the wheelchair. This master-slave motion control system can help to eliminate patients’ fear of medical apparatus and instruments. The bicycling motion actuated by one motor is implemented to realize the rehabilitation motion exercise. Experimental results validate a position-force control strategy for the exoskeleton motors, and show that the proposed method can help users to move around and to exercise their legs simultaneously and effectively.
