Timed Failure Propagation Graphs (TFPGs) have been widely used for the failure modeling and diagnosis of safety-critical systems. Currently most TFPGs are manually constructed by system experts, a process that can be time-consuming, error-prone, and even impossible for systems with highly nonlinear and machine-learning-based components. This letter...
Tato diplomová práce se zabývá návrhem systému aktivního řešení kosmické tříště. Kosmická tříšť, nebo také kosmický odpad, je pojem používaný v kosmonautice k popisu všech antropogenních, neaktivních vesmírných objektů, fragmentů a zbytků všeho, co vzniklo rozpadem kosmické technologie, která byla vypuštěna na oběžnou dráhu člověkem. Kosmická tříšť...
Technological evolution and mass production is impacting the Earth daily due to global warming caused by greenhouse gas emissions, where the biggest factor is the emission of carbon dioxide mostly caused by the burning of fossil fuel and industrial processes. Therefore, alternatives for substituting the use of fossil fuel in industries are extremel...
ABSTRACT The article explores the reuse of technical processes in the manufacturing of space systems, from the perspective of establishing a database of technical manufacturing processes for use by space organizations. It will be argued that the reuse of processes is made feasible when a database of processes is implemented and that the reuse of te...
Earth's magnetosphere is vital for today's technologically dependent society. The energy transferred from the solar wind to the magnetosphere triggers electromagnetic storms on Earth, knocking out power grids and infrastructure - e.g., communication and navigation systems. Despite occurring on our astrophysical doorstep, numerous physical processes...

Les satellites glacés de Jupiter sont d'un grand intérêt scientifique dans la recherche d'habitabilité au sein de notre système solaire. Elles abritent probablement toutes trois des océans d'eau liquide sous leur croûte glacée. Leurs surfaces présentent différents stades d’évolution – celle de Callisto est très ancienne et entièrement recouverte de...

Quantum key distribution (QKD) is a key exchange protocol which is implemented over free space optical links or optical fiber cable. When direct communication is not possible, QKD is performed over fiber cables, but the imperfections in detectors used at the receiver side and also the material properties of fiber cables limit the long-distance comm...
