This paper studies the communication time-delay issue in islanded microgrids (MGs) with distributed secondary control architecture. Firstly, a time-delayed MG small-signal model is developed. Then, new weight-average-prediction (WAP) controller proposed to compensate delayed system states. By introducing differential term law, traditional transformed into neutral mathematic model. Based on deve...

PURPOSE The average delay from first seizure to diagnosis of psychogenic non-epileptic seizures (PNES) is over 7 years. The reason for this delay is not well understood. We hypothesized that a perceived decrease in seizure frequency after starting an anti-seizure medication (ASM) may contribute to longer delays, but the frequency of such a response has not been well established. METHODS Time ...

Under water sensor network protocol research is a hot research topic in the networking field. These protocols are designed on the basis of UWSN application requirements. Selection of protocol is depends on the basis of system requirement and its application. Real time applications are time variant and require reliability for communicating in side water. Average time to time Delay of nodes is th...

This paper studies the performance of a feedback control loop closed via an error-free digital communication channel with transmission delay. The system comprises discrete-time noisy linear time-invariant (LTI) plant whose single measurement output is mapped into its input by causal, but otherwise arbitrary, coding and scheme. We consider single-input multiple-output (SIMO) between encoder-cont...

We observe that the state-of-the-art power-saving mechanisms (PSM) for IEEE 802.16e is neither optimal in terms of delay nor in terms of energy consumption. We propose a new PSM which achieves the optimality in terms of the average buffering delay without increasing energy consumption. In order to do so, we derive a formula which relates the average buffering delay to sleep intervals. Simulatio...

Average delay is perhaps the most commonly used measure for characterizing the performance of signalized intersections. Current methodologies for estimating the average delay rely on the use of models based on volumes and green times. In practice, it is challenging to develop such real-time measurements of delay, due to the difficulty of accurately measuring vehicle arrivals and departures. How...

We analyse the average case complexity of evaluating all preexes of an input vector over a given semigroup. As computational model circuits over the semigroup are used and a complexity measure for the average delay of such circuits, called time, is introduced. Based on this notion, we then deene the average case complexity of a computational problem for arbitrary input distributions. For highly...

When transmitting stochastically arriving data over fading channels there is an inherent trade-off between the required average transmission power and the average queueing delay experienced by the data. This trade-off can be exploited by appropriately scheduling the transmission of data over time. In this paper, we study the behavior of the optimal power-delay trade-off for a single user in the...

We consider a network in which a set of vehicles is responsible for the pickup and delivery of messages that arrive according to Poisson process with message pickup and delivery locations distributed uniformly at random in a region of bounded area A. The vehicles are required to pickup and deliver the messages so that the average delay is minimized. In this paper, we provide lower bounds on the...
