The cellular users, on high speed railways and highways, travel at a very high speed and follow a nearly straight path, in general. Thus, they typically undergo a maximum frequency of handovers in the cellular environment. This requires a very fast triggering of the handover. In the existing method of handover in 5G cellular communication, for high speed users, neither the decision-making of handover nor the triggering of handover is sufficiently fast. This can lead to poor signal quality and packet losses and in the worst case, radio link failure (RLF) during a handover. This paper proposes a forward handover based method, combined with PN sequence detections, to facilitate a quicker handover for high speed users on railways and highways. The proposed method adds some complexity but can offer a significant improvement in the overall handover delay. A simplistic simulation is used to demonstrate the improvement of the proposed method.

Recording of krill swarms and the observations of the state of the sea and the force of wind were conducted on the M/T "Gemini" from 6 to 26 February, 1978, eastwards of the South Orkneys Archipelago. It has been found that a heavy sea and strong winds disperse krill swarms. At night krill swarms occur much more frequently than during the day.

The method of target strength measurement adopted for the krill's target strength determination is proposed. The relation between the length of krill's individual and its target strength, obtained at the laboratory conditions, is presented.
