By the time a child is three, they should have mastered all the skills necessary to communicate with the adults and children in their environment. However, studies show that approximately seven per cent of all children in the UK do not develop those skills.

Hypercube communication delay with wormhole routing
IEEE Transactions on Computers, 1994Summary: We present an analytical model for the performance evaluation of hypercube computers. This analysis is aimed at modeling a deadlock-free wormhole routing scheme prevalent on second generation hypercube systems. Probability of blocking and average message delay are the two performance measures discussed here.

ON THE COMPLEXITY OF SCHEDULING WITH COMMUNICATION DELAY AND CONTENTION
Parallel Processing Letters, 1995We show the NP-Completeness of two processor scheduling with tasks of execution time 1 or 2 units and unit interprocessor communication latency. We develop a model of scheduling in the presence of communication contention, and show the NP-Completeness of two processor scheduling with unit execution time tasks in our model.

The Complexity of Scheduling Trees with Communication Delays
Journal of Algorithms, 1996Summary: We consider the problem of finding a minimum-length schedule on \(m\) machines for a set of \(n\) unit-length tasks with a forest of intrees as precedence relation, and with unit interprocessor communication delays. First, we prove that this problem is NP-complete; second, we derive a linear time algorithm for the special case that \(m ...

Abstract We present results from simulated deep-space exploration missions that investigated voice communication with significant time delays. The simulations identified many challenges: confusion of sequence, blocked calls, wasted crew time, impaired ability to provide relevant information to the other party, losing track of which messages have ...

Position Tracking Control of Remotely Operated Underwater Vehicles With Communication Delay
IEEE Transactions on Control Systems Technology, 2020Many marine missions demand a single remotely operated underwater vehicle (ROV) or multiple ROVs to achieve position tracking. However, the time-varying communication delay in water makes it challenging to achieve the tracking task.
