Summary: Exoskeleton robots have found applications in various areas such as neurorehabilitation, telemanipulation, and power augmentation. However, existing attachment concepts have imposed limitations on the performance of modern exoskeletons due to issues like insufficient stiffness, time-consuming adaption processes, and bulkiness. In this study, an augmented attachment system was proposed and compared to a conventional solution. The results showed that the proposed system significantly reduced the relative motion between the human and the robot, mitigated undesired contacts, and facilitated better alignment with the user's anatomy.

Summary: In this paper, the performance of a traditional PID controller in an autonomous vehicle is analyzed. The controller cannot accurately track ramp references, resulting in significant deviation from the desired vehicle behavior. To address this issue, a fractional controller is proposed, which allows for faster responses for small times while sacrificing response speed for larger times. By utilizing this controller, the vehicle is able to accurately follow variable speed references and significantly reduce the discrepancy between reference and actual vehicle behavior. The designed fractional PID controller outperforms the standard PID controller.

Summary: Disruptive technologies and novel aircraft generations are seen as potential solutions to achieve ambitious emission reduction goals in aviation. However, the introduction of innovative concepts can be time-consuming and may not produce the optimal design within the given timeframe. To overcome this, the Advanced Morphological Approach (AMA) was introduced, which involves decomposing design problems, evaluating alternatives, and projecting solutions onto a solution space. This paper focuses on integrating structured expert judgment elicitation (SEJE) techniques into conceptual aircraft design with AMA, and applies it to wing morphing architecture.

Summary: The corrosion behavior of 30CrMnSiA steel in different environments was investigated, and the results showed that corrosion was most severe in the outdoor environment, followed by the sheltered environment, and least severe in the storehouse environment. The corrosion current density decreased with exposure time, indicating a correlation between the density of corrosion products on the surface and the degree of corrosion.
