the ability to perform rolling contact fatigue (rcf) experiments in wheel–rail material is provided by a new small–scale test rig, manifesting the actual dynamic behaviour of the railway system. in this paper, a multi-body dynamics (mbd) model is proposed, simulating the vibration behaviour of the prescribed rig. the new testing facility is modelled using a three-dimensional model of the vehicl...

Audio and video data have become critical components of information systems and these systems need to e ciently manage the large storage requirements of this type of data. However, there are no formal data models for audio video data. In this paper, we present an algebraic formalism which attempts to provide the underpinnings for the design and implementation of systems which organize and query...

Due to the complexity and requirements of modern real-time systems, multiple teams must often work concurrently and independently to develop the various components of the system. Since a team typically only knows the dependency relations between the components they wrote and those they directly use, keeping track of system-wide dependency relations is not possible for any individual team. To fu...

In this contribution we present new developments and results for the LIT track reconstruction package for CBM in the CbmRoot framework. The reconstruction package is organized to be flexible with respect to feasibility studies of different physics channels and to optimization of the detector geometries. The tracking software has been redesigned to make it more general and to simplify the suppor...
