Abstract: Background: In This Paper, We Propose A Solution To Image Completion Using Deep Neural Networks Has Become A Hot Research Area. As Structure And Texture Are Two Indispensable Parts Of Images, Completion Algorithms Must Deal With Them Appropriately To Produce Realistic Results. However, Many Current Methods Use The End-To-End Framework To Repair An Image, Which Do Not Pay Special Attention To Texture And Structure. Therefore, They Often Generate Distorted Structures And Inconsistent Textures. To This End, We Propose A Novel Image Completion Method Comprising A Sketch Completion Network Followed By A Texture Completion........

Abstract: In a two-dimensional plane, for a target in uniform linear motion, a stationary single station is assumed to be able to acquire the orientation information of the target in three consecutive equally spaced steps along the target's travelling path. Firstly, the trigonometric relationship is used to arrange the defining equation, from which the path difference between radial distances is obtained. Then the angle of arrival of the target relative to the detection station is determined with the help of the single-base midpoint direction finding formula, and then the heading angle of the target can be obtained from the relationship between the internal and external angles. The error analysis shows that the measurement accuracy obtained with the further help of single base mid-point direction finding method based on trigonometric fixed solution equations is better than that based on trigonometric method only.

Abstract: A new realization of the ground segment sub systems of an existing telecommand system for balloon borne payloads, using modern technology is described in this paper. Existing telecommand system (Ghosh & Tandon, 1982), has been working from last many years during TIFR 100 cm (T100) far infrared balloon flights (Mookerjea B. et al., 2003; Kaneda et al., 2013; Suzuki et al., 2021). This system was designed and realized for on line payload control during balloon flight campaigns. Upgradation for the ground system is required considering the fact that, the older system uses many of the discrete components and some of the components are obsolete. Sometimes it becomes difficult to debug and repair the system in certain situations considering the lack of support of outdated and obsolete compilers.....
