As part of the "ESA_Lab@" initiative, a Concurrent Engineering facility has been constructed at the Mechanical Engineering department of Technical University Darmstadt. Concurrent Engineering is a well-proven concept for designing complex space systems and missions in the pre-phase 0/A mission phase. The Concurrent Engineering methodology and processes are enabled by a multidisciplinary team and specific infrastructure in terms of both hardware and software, which generate an effective and time efficient design management system. The university's "Concurrent Engineering Lab" provides an environment for both researchers and students to explore and apply the Concurrent Engineering approach in areas such as (model-based) systems engineering, Industry 4.0/Space 4.0, and space traffic management. Furthermore, collaboration with the European Space Operations Centre - also located in Darmstadt - regarding the application of Concurrent Engineering for Ground Segment & Operations has been started. The first addition to the university's curriculum centered around the Concurrent Engineering Lab will be a "Concurrent Engineering Tutorial", an opportunity to introduce the Concurrent Engineering methods and tools via hands-on experience to students of the newly established master's degree program "Aerospace Engineering". "Tutorials" are elective block courses of the degree program which offer practical learning experiences in many different fields, awarding 4 credit points upon successful completion. Building on the lectures "Fundamentals of Space systems" and "Space systems and Space Operations", the week-long "Concurrent Engineering Tutorial" will challenge students to use their acquired knowledge to develop a preliminary design for a predefined CubeSat mission. This Tutorial will not only provide a closer understanding of the individual subsystems of the space segment of a mission, the Concurrent Engineering process and the relevant software "COMET" by RHEA Group but will also
The standard edge detection method via fourier single-pixel imaging encodes the scene with Fourier patterns modulated by Sobel operators, which can directly reconstruct the object edges instead of the complete scene. ...
