Opis:: China’s Maritime Education and Training (MET) has been providing numerous talents for its shipping industry in the past decades. However, the traditional Chinese MET emphasized more on crew training but ignored shipping services’ fields. This paper firstly redefines the concept of MET from a broader perspective, then outlines the current status quo of MET in China from the new broader angle, consequently analyzes the main problems of Chinese MET, and finally proposes suggestions for regarding governments, institutions, as well as shipping companies, aiming to offer valuable ideas during the process of decision-making.

Opis:: Two different procedures for the study of the quenching of excited states by lanthanide complex ions on the surface of micelles are considered. In the first, excited Tb(pdc)$\text{}_{3}^{3-}$ (pdc = pyridine 2,6-dicarboxylate) complex ions are held in close proximity to other Ln(pdc)$\text{}_{3}^{3-}$ ions on the surface of cetyl trimethyl ammonium micelles. Efficient energy transfer is observed by the electric dipole-electric dipole mechanism with a mean interaction distance only slightly greater than that which exists in the crystalline complexes. In the second, the excited state of Tb(pdc)$\text{}_{3}^{3-}$ is depopulated by energy transfer to the coexcited lowest excited triplet state of phenanthrene which is thereby excited to the second triplet state.

Tematy:: multifocus image fusion

superior speed
Opis:: In order to improve and accelerate the speed of image integration, an optimal and intelligent method for multi-focus image fusion is presented in this paper. Based on particle swarm optimization and quantum theory, quantum particle swarm optimization (QPSO) intelligent search strategy is introduced in salience analysis of a contrast visual masking system, combined with the segmentation technique. The superiority of QPSO is quantum parallelism. It has stronger search ability and quicker convergence speed. When compared with other classical or novel fusion methods, several metrics for image definition are exploited to evaluate the performance of all the adopted methods objectively. Experiments are performed on both artificial multi-focus images and digital camera multi-focus images. The results show that QPSO algorithm is more efficient than non-subsampled contourlet transform, genetic algorithm, binary particle swarm optimization, etc. The simulation results demonstrate that QPSO is a satisfying image fusion method with high accuracy and high speed.

Opis:: In this research, sterile soil columns with different contents of biochar made from apple-tree residues (0, 1 and 5% w/w) at three levels of water filled pore space (40, 60, and 80%) were set up in the laboratory to study nitrous oxide diffusion and binding processes. The results indicated that nitrous oxide emission can be effectively mitigated at 5% biochar regardless of soil water content. However, 1% biochar stimulated nitrous oxide diffusion compared to the other biochar treatments, which was opposite to expectations due to the stronger aeration than adsorption effect, while 0% had a suppression effect between 1 and 5%. Nitrous oxide emissions increased with increasing water filled pore space due to concomitantly decreasing biochar tortuousity at high water content. The increase of nitrogen from 1.11 to 1.50% on the biochar surface in the 5% treatment, and from 1.11 to 1.46% in the 100% biochar treatment, suggested that the main abiotic mechanisms for mitigation of nitrous oxide emission is adsorption and subsequent reactions with C = C bonds on appletree biochar surfaces since C = O and C-O bonds both increased and C=C/C-C/C-H declined.

Opis:: Gully erosion is an important form of soil erosion, however, little was done on the effect of gully erosion controlling approaches. A program for controlling gully erosion was carried out in Heshan Farm in black soil region of northeast China from 1994 to 1996 include two approaches: "Soil fill" and "Vegetation cover". From the investigation at 2009, Soil fill approach can protect the original place of gully erosion well, but this apporach ignores the whole impact at the catchment scale, and may cause to new gully appear. "Vegetation cover" approach is better to control gully erosion than "Soil fill" approach, but has little effect on controlling the headcut retreat.

Opis:: To realize “seamless” connection of ocean port container multimodal transport, efficiently carry out “door-to-door” transport of ocean port containers and overcome the shortcomings of existing highway and railway vehicles, this study takes the standard for heavy-duty container vehicles in TB1335-1996 Railway Vehicle Strength Design and Test Identification Code as the design basis and designs a new ocean port container transport vehicle in combination with automatic guidance technology. This study innovatively designs the automatic lifting system of the bogie and the docking part of the vehicle, introduces the automatic guidance technology and the remote-control technology to optimize the car body structure, and uses the SAP software to carry out the finite element analysis of the car body load capacity and Flexsim software to carry out the simulation analysis on the operation of vehicles. The designed transfer vehicle can improve the transfer efficiency of ocean port containers, reduce the transit time of field and station equipment and container transport links, and improve the level of multimodal transport and comprehensive economic benefits.

Opis:: Thermal behavior and microstructure of $Fe_{81 - x}Co_{x}Zr_7Nb_2B_{10}$ (x = 2, 4, 6) alloys were investigated by differential thermal analysis and X-ray diffraction. Both the supercooled liguid region Δ $T_{x}$ and the first crystallization peak temperature $T_{p1}$ are the lowest and the span Δ $T_{p}$ between $T_{p1}$ and $T_{p2}$ is the highest when 4 at.% Fe is substituted by Co. The crystallization activation energy $E_{p1}$ for $Fe_{75}Co_6Zr_7Nb_2B_{10}$ alloy is the minimum for the heating rates ν = 5-20 K/min. $E_{p1}$ for $Fe_{77}Co_4Zr_7Nb_2B_{10}$ alloy is the minimum for the heating rates ν = 20 - 50 K/min. The crystallization processes of $Fe_{81 - x}Co_{x}Zr_7Nb_2B_{10}$ (x = 2, 4, 6) amorphous alloys are similar on the whole, which is as follows: amorphous → amorphous + α-Fe(Co) → α-Fe(Co) + $Fe_3Zr$ + $Fe_2Nb_{0.4}Zr_{0.6}$.

Opis:: Compression is one of the typical parameters measured in material mechanics. In this research, the compression displacement fields on the front and rear surfaces of an epoxy sample are measured by using a tilt depth-resolved wavenumber-scanning Michelson interferometer. The light source is a distributed feedback laser diode, the wavenumber of which can be modulated to about 1.017 × 10⁴ m^–1 by the temperature without mode hopping. A random-sampling Fourier transform is designed to evaluate the phase differences before and after the applied loads. Experimental results show that the depth-resolved measurement of the compression displacement field is of high accuracy. It can be used to analyze force propagation inside resin-based composites.
