The binding interaction between bovine hemoglobin (BHb) and a novel two-dimensional carbon nanomaterial, graphene oxide (GO), has been investigated in this work. It is found that GO strongly disturbs the secondary structure of BHb by forming BHb-GO aggregates. The binding affinity between the GO and BHb is shown to be mainly from non-covalent interactions including hydrophobic, hydrogen bonding, van...
Based on analyzing the situation of current underwater navigation, this paper presents an independent underwater navigation method, namely the terrain matching algorithm based on contour image. Firstly, according to multibeam bathymetric system data, the topographic contours are extracted out from the data and then form contour image. Secondly, the contour used for image matching is coded. The coding...
This paper presents a new method to fulfill the contour match of seabed topography through image match algorithms. Firstly, the generation of topographic contour image is studied. Then, the theory of image matching is introduced. Based on above, a complete matching process is given out. Finally, a positioning experiment is implemented by means of contour image match. Positioning accuracy is better...
Inertial navigation system (INS) is an independent navigation system, but is difficult to be used in far-distance and long-time navigation due to INS accumulation error. Thus, a new synthetic navigation system for underwater based on the integration of INS and multibeam bathymetric system (MBS) is studied and presented in the paper. Firstly, we introduce the composition of the underwater navigation...
