Ultra-lightweight, membrane primary mirrors offer a promising future for space telescope technology. However, the advantages of the lightweight structure of the mirror are restricted by an extremely high susceptibility to microyield. Hence, careful packaging of the membranes is required when transporting mirrors of this type into space. Four packaging models, a cylindrical roll, an umbrella mod...

One of the challenges of dealing with multiple contexts is the significant effort required to provide all necessary lifting rules so that statements in one context can be viewed and understood in other contexts. In this paper, we introduce the notion of structured contexts, where a lightweight ontology is used to provide a structure for representing contexts. With structured contexts, specializ...

The implementation of lightweight high-performance motion systems in lithography and other applications imposes lower requirements on actuators, amplifiers, and cooling. However, the decreased stiffness of lightweight designs increases the effect of structural flexibilities especially when the point of interest is not at a fixed location. This is for example occurring when exposing a silicon wa...

The table recognition model rows and columns aggregated network (RCANet) uses a semantic segmentation approach to recognize structure, achieves better performance in row column segmentation. However, this ResNet18 as the backbone network, has 11.35 million parameters volume of 45.5 M, which is inconvenient deploy lightweight servers or mobile terminals. Therefore, from perspective compression, ...

Abstract The application of diamond material significantly improves the heat dissipation capability liquid cooling microchannels, solving bottleneck problem for highly integrated electronic components and thus promoting development a new generation military equipment. In this study, microchannels with ultra-high flux density were reliably vacuum-brazed by using AgCuTi filler metal in high vacuu...
