Konferensbidrag (refereegranskat)abstract
- The Visual Object Tracking challenge VOT2017 is the fifth annual tracker benchmarking activity organized by the VOT initiative. Results of 51 trackers are presented; many are state-of-the-art published at major computer vision conferences or journals in recent years. The evaluation included the standard VOT and other popular methodologies and a new "real-time" experiment simulating a situation where a tracker processes images as if provided by a continuously running sensor. Performance of the tested trackers typically by far exceeds standard baselines. The source code for most of the trackers is publicly available from the VOT page. The VOT2017 goes beyond its predecessors by (i) improving the VOT public dataset and introducing a separate VOT2017 sequestered dataset, (ii) introducing a realtime tracking experiment and (iii) releasing a redesigned toolkit that supports complex experiments. The dataset, the evaluation kit and the results are publicly available at the challenge website(1).

- The reduction kinetics of cold-bonded briquette prepared from return fines of sinter is studied. The results reveal that cold-bonded briquettes with coke (CBBC) have a higher reduction velocity index (RVI) value than cold-bonded briquettes without coke (CBB). Interfacial chemical reaction controls the early stages of the CBB reduction process at 900 and 950 °C, followed by both interfacial chemical reaction and internal diffusion. At 1000, 1050, and 1100 °C, the early and final stages of the CBB reduction process are controlled by interfacial chemical reaction and internal diffusion, respectively, while both interfacial chemical reaction and internal diffusion control middle stage. The apparent activation energies of the different stages are 46.20, 56.74, 38.24, and 40.74 kJ mol−1, respectively. The gasification of carbon reaction controls the reduction process of CBBC, and the apparent activation energy is 32.42 kJ mol−1. According to the Friedman method, the apparent activation energy of CBB and CBBC is reasonable. Coke promotes the phase transformation in CBBC. Scanning electron microscopy results show that the CBBC sample is more fully reduced than the CBB sample and that it has smoother corners and edges of the iron-bearing phase or the metallic iron phase than the CBB sample.

- In situ high-pressure angle-dispersive synchrotron X-ray diffraction and high-pressure mid-infrared (IR) spectrum measurements of C60H18 were carried out up to 32 and 10.2 GPa, respectively. Our diffraction data indicated that the fcc structure of C60H18 was stable up to 32 GPa. The bulk modulus B0 was determined to be 21 ± 1.16 GPa, about 40% higher than that of C60. The C−H vibrations still existed up to 10.2 GPa, and the vibrational frequencies decreased with increasing pressure. IR-active vibrational frequencies and their corresponding eigenvectors of C60H18 were simulated by DMOL3. The effects of the hydrogen atoms attached to the fullerene molecular cage on the stability of the structure under high pressure are discussed.
