The at least one memory and the computer program code may be configured to, with the at least one processor, cause the client device to: receive a measurement configuration from a first network node device, receive a preconfigured condition for the measurement configuration from the first network node device, and in response to the preconfigured condition for the measurement configuration being fulfilled, use the measurement configuration. A client device, a network node device, methods, and computer programs are disclosed.

Abstract: Audio video synchronization and alignment or alignment of audio to some other external clock are rendered more effective or easier by treating fragment grid and frame grid as independent values, but, nevertheless, for each fragment the frame grid is aligned to the respective fragment's beginning. A compression effectiveness lost may be kept low when appropriately selecting the fragment size. On the other hand, the alignment of the frame grid with respect to the fragments' beginnings allows for an easy and fragment-synchronized way of handling the fragments in connection with, for example, parallel audio video streaming, bitrate adaptive streaming or the like.

Abstract: A method is provided for determining a state of a distillation column having multiple column stages for separating a feed fluid stream into individual fluid components. The state is determined by means of a model in a manner dependent on pressure differences prevailing between adjacent column stages. In the model, both gaseous and liquid flows between adjacent column stages are brought about by the pressure differences prevailing between adjacent column stages. A substance quantity flow characterizing gaseous flow between two column stages is given by {dot over (N)}V·RV=CV·?pV. A substance quantity flow characterizing liquid flow between two column stages is given by {dot over (N)}L·RL=CL·?pL. ?pV,L is a total pressure difference between two adjacent column stages. RV,L is a coefficient of resistance between two adjacent column stages and CV,L is a conductance value of flow between two adjacent column stages.
