In material research, it is often highly desirable to observe images of whole microscopic sections with high resolution. So that micrograph stitching is an important technology to produce a panorama or larger image by combining multiple images with overlapping areas, while retaining microscopic resolution. However, due to high complexity and variety of microstructure, most traditional methods could not balance speed and accuracy of stitching strategy. To overcome this problem, we develop a method named very fast sequential micrograph stitching (VFSMS), which employ incremental searching strategy and GPU acceleration to guarantee the accuracy and the speed of stitching results. Experimental results demonstrate that the VFSMS achieve state-of-art performance on three types’ microscopic datasets on both accuracy and speed aspects. Besides, it significantly outperforms the most famous and commonly used software, such as ImageJ, Photoshop and Autostitch.

A suite of snow and ice penetrating radar arrays, used for polar remote sensing, have been developed by a team of University of Kansas and DARcorporation engineers in support of the NASA Operation Ice-Bridge program. This collaborative industry/academic partnership provided design, analysis, fabrication and testing of antenna fairings for the above mentioned radar array, as well as subsequent installation and flight testing on a Lockheed P-3 Orion aircraft. This installation has since flown multiple successful missions, generating in excess of 150TB of snow and ice data. This paper discusses the effect of the antennas on the aerodynamics, and performance, as well as the structure and manufacturing of the pylons and the antenna fairings.

This paper describes the preliminary design, structural layout, detailed sizing and manufacturing of an uninhabited air vehicle (UAV) that will primarily be used to measure changes in glacial conditions in Antarctica and Greenland. This includes a brief description of the requirements definition and preliminary configuration design. Preliminary component weight estimations are created using empirical formulas then compared to the results of structural sizing using finite element analyses. The goal of this effort is to design an aircraft capable of autonomous operation in extreme climates that can carry various sensors including radar depth sounders and magnetometers.
