If the number of users with delay sensitive traffic is relatively large, then polling or contention-free access is inappropriate because of the large delay incurred in waiting for one's turn [17].
Because of the large delay which may lead to serious disasters [8, 11, 18, 24, 36, 47], such as monitoring of industrial boiler temperature and industrial furnace metallurgy, if the control is not timely, may lead to explosion of the boiler, the product quality does not meet the requirements and results in waste.
This is because for the large-delay-spread channel, the coherent bandwidth of the channel is relatively small, which drastically reduces the accuracy of subcarrier domain interpolation (i.e., frequency domain interpolation) estimation in the 2-D method.
In reality, using a single agent is not practical because of large delay, unbalanced load, and large accumulated size [21, 22].
Because of the large transport delay involved in the feedback loop of the AF-ratio controller, a simple PI controller would not be sufficiently accurate to guarantee an adequate response of the system.
However, it has become more and more difficult to improve their load change capabilities just through coordinated control system because of boiler's large delay.
That is partly because the larger developers have delayed many of their more complex titles until 2015, but also because many of the coders are showing off genuinely innovative titles that stand out from the torrent of shooters and luxury car racing games.
This approach is rarely used in NoSQL because it can result in large delays in the case of temporary loss or degradation of the connection.
Because U has a very large delayed neutron fraction (Table 8), replacing LEU with HEU reduces the fast fission portion of U and results, the value of βeff decreases.
It is also noted that polling is known to be very efficient throughput-wise, but leads to large delays because a user has to wait for his/her turn to transmit [17].
