In order to acquire and share a better understanding architectural changes, researchers face the challenge of modelling and representing events (cause and consequences) occurring in space and time, and for which assessments of doubts are vital. This contribution introduces a visualisation designed to facilitate reasoning tasks, in which a focus view on evidence about what happens to artefact λ ...

the purpose of this study is to investigate the impact of bureaucratic structure on the employee engagement (ee). our study extends previous researches by considering bureaucracy from two points of view: enabling versus hindering. we study the extent to which these two types of bureaucracy are related to the two forms of employee engagement: organizational (oe) and work engagement (we). the vie...

Trajectory tracking of nonlinear dynamical systems with affine open-loop controls is investigated. The control task is to enforce the system state to follow a prescribed desired trajectory as closely as possible. We introduce exactly realizable desired trajectories as these trajectories which can be tracked exactly by an appropriate control. Exactly realizable trajectories are characterized mat...

This paper investigates the problem of enhancing a single desired speech source from a mixture of signals in multispeaker environments. A beamformer structure is proposed which combines a fixed beamformer with postfiltering. In the first stage, the fixed multiobjective optimal beamformer is designed to spatially extract the desired source by suppressing all other undesired sources. In the secon...
