                      onboard the International Space Station enables us to
                      closely follow the evolution of outbursts of X-ray binaries
                      on a variety of time scales with high sensitivity data.
                      Using these observations we were able to study in detail the
                      evolution of quasi-periodic oscillations (QPOs) and noise
                      components in different outburst states and during state
                      transition. Our studies allowed us to gain further insights
                      in the evolution of QPOs and to follow in more detail the
                      formation and disappearance of the different types of these
                      oscillations. In addition to power-density spectra we also
                      studied the evolution of energy spectra. Based on
                      theoretical models we derived from the QPO properties and
                      spectral parameters radii of the different components of
                      X-ray binaries and followed their evolution during
                      outburst.We will present the results of our studies of the
                      evolution of timing and spectral properties in outbursts of
                      GX 339-4 and Swift J1727.7-1613 and discuss them in light of
                      different QPO models and what they tell us about the
                      accretion geometry.},
