C.F. Møller Architects have collaborated with Kristin Jarmund Architects and Rodeo Architects in the design of a new urban realm at Oslo Central Station in Norway, comprising a square, hotel, and high-rise building. The scheme seeks to create an attractive recreational area around the transpor...
agency also has promised the mission will see a woman and person of color walk on the moon for the first time. In the fourth Artemis mission, Starship might dock at a moon-orbiting space station, theyet-to-be-commissioned Gateway, and ferry astronauts back and forth to the moon from ...
The taikonauts -- Chen Dong, Liu Yang and Cai Xuzhe, who are on a six-month stay in orbit, shared with the African youth their life and scientific work in the space station. The main venue of the event, titled "Talk with Taikonauts," was held at the headquarters of the African Union...
We therefore measured hemolysis markers in breath and blood samples from astronauts preflight, four times inflight and up to 1 year after their 6-month missions to the International Space Station (ISS). A total of 14 astronauts were recruited (11 men and 3 women; 45 ± 7 years) ...

The task of target recognition should be done autonomously to minimize the risk of collision in space13. The vision-based sensor such as camera2,14,15,16 is the most significant component in SSA to observe visual data and build data-driven AI solution. Various methods have been proposed in ...
Therefore, the modeling of power electronic circuits comes under non-linear structure systems as sudden changes are introduced in their differential equations [11,12,13,14]. The mathematical modeling of DC-DC converters is a crucial step in the design and analysis of these electronic devices. In...
