The explosive growth of micro-satellites has brought about increasingly saturated competition for low Earth orbit resources, and more complex potential needs of on orbit operations grow quickly. Aerospace robotic arms are still the most important optimal option to replace human beings to perform complex operation tasks for a long term. Faced with extreme requirements and environmental constraints different with on the ground, the miniaturization of the electronic system is the bottleneck that determines space robots' performance and energy efficiency ratio. This paper proposes an architecture of reconfigurable integrated processing microsystem for the application of micro space dual arm robotics. The core architecture design is studied from the task demand orientation, with processing, communication, sensing, execution, control and other functions in a highly integrated architecture, through system modeling, simulation and software hardware collaborative design. A corresponding assessment is provided for the subsequent implementation of hardware system miniaturization using the microsystem 3D integration process.

computer vision-based systems hold great potential for assisting experts during visual inspections of civil infrastructures. They can enhance efficiency and objectivity in detecting and characterizing anomalies, thereby supporting maintenance obligations. Here, we report on the image semantic segmentation of multiple bridge defects (Crack, Corrosion, Rebar Corrosion and Spallation) within a Vision Transformers (ViT)-Adapter framework. ViTs have shown outstanding performance on a variety of tasks provided they are correctly pre-trained. By capitalizing on publicly available datasets with self-supervised pre-training methods (DINO, iBOT, SupMAE), segmenter models were efficiently trained for each defect category with minimal annotation efforts. Self-supervised pre-training on a medium-scale specific dataset was found to outperform supervised pre-training on both a massive generalist dataset (SA-1B) and a small specific dataset. More specifically, SupMAE exhibited a propensity for preparing the segmenter to handle "stuff" defects (Crack, Corrosion, and Spallation), while DINO demonstrated better performance for "thing" defects (Rebar Corrosion).
Safety-critical systems are increasingly model-based, since model-based system engineering (MBSE) paradigm reduces the time-to-market and allows evolving systems at different abstraction levels. Different languages ha...

Designing a fallback authentication mechanism that is both memorable and strong is a challenging problem because of the trade-off between usability and security. This challenge is particularly pronounced for accounts that require infrequent authentication, where the authentication secrets must remain secure and easy to recall without frequent reinforcement. Inspired by people's strong visual-spatial memory and memory via association, we introduce a novel system AuthZit to help address this problem. AuthZit encodes authentication secrets as paths through a 3D map of places in real life navigated in the first person and birds-eye perspective, along with a textual secret tagged with this path. We evaluated the usability and security of our design in two dimensions: memorability after one month and speed through a user study with 20 participants. Our results suggest that (1) user authentication secrets in AuthZit are memorable, and (2) authentication using AuthZit was not significantly slower to enter.
