Context. The dynamics of the solar core cannot be properly constrained through the analysis of acoustic oscillation modes. Gravity modes are necessary to understand the structure and dynamics of the deepest layers of the Sun. Through recent progresses on the observation of these modes – both individually and collectively – new information could be available to contribute to inferring the rotati...

In this thesis, an integrated approach is developed for the regional renement of global gravity eld solutions. The analysis concepts are tailored to the in-situ type character of the observations provided by the new satellite missions CHAMP, GRACE, and GOCE. They are able to evaluate data derived from short arcs of the satellite's orbit and, therefore, oer the opportunity to use regional satell...

Due to the cumbersome nature of performing real microgravity—spaceflight research scientists have been searching for alternatives to perform simulatedmicrogravity or partial gravity experiments on Earth. For more than a century one uses the slow rotating clinostat as developed by von Sachs at the end of the nineteenth century. Since then, the fast rotating clinostat, the 3D clinostat or the ran...

This paper investigates means to benchmark methods for camera pose localization and tracking that in addition to a camera image make use of inertial sensor measurements. In particular the direction of the gravity has recently shown to provide useful information to aid vision-based approaches making them outperform visiononly methods. Obviously, it is desirable to benchmark the performance of su...

We assume that the fourdimensional quantum gravity is scale invariant at short distances. We show through a simple scaling argument that correlation functions of quantum fields interacting with gravity have a universal (more regular) short distance behavior. We consider the tetrads ea(x) as the basic variables for quantum gravity. We assume that correlation functions of ea(x) are scale invarian...

measuring field gravity in sea due to the accelerations introduced via waves and movements to the gravity measuring systems has a low accuracy since according to einstein's equalent principle, gravimeter isn't able to separate the gravity acceleration from another acceleration. ship borne gravimetery observations by means of like oscillations and accelerations of the ship motion, and ...
