Motivated by interest in making delay announcements to arriving customers who must wait in call centers and related service systems, we study the performance of alternative real-time delay estimators for the delay before entering service of an arriving customer based on recent customer delay experience. We characterize performance by the bias and the mean squared error (MSE) We do analysis and ...

We show that the anomalously short delay times observed in barrier tunneling have their origin in energy storage and its subsequent release. The observed group delay is proportional to the energy stored. This delay is not a propagation delay and should not be linked to a velocity since evanescent waves do not propagate. The "Hartman effect", in which the group delay becomes independent of thick...

ABSTRACT The paper provides a complete analysis of the APS pixel and column circuit delay. Contrary to common belief, we show that shorter settling times can be achieved by reducing the bias current and hence reducing energy consumption. We then investigate the effect of non-idealities on the readout operation. We find that when the follower transistor channel length modulation is taken into co...

have also given a linear time algorithm to determine the set of possible root locations for a minimum diameter shortest path tree, and shown that any minimum diameter tree must pass through this region. When compared with the 1-Steiner algorithm, minimum diameter A-trees produced lower maximum and average delays, with slightly higher tree length. Consideration of the feasible center region resu...

Reliability issues, such as soft errors, process variations and Negative Bias Temperature Instability (NBTI), become dominant on Field Programmable Gate Arrays (FPGAs) fabricated in a nanometer process. We focus on aging degradation by NBTI, which causes threshold voltage shifts on PMOS transistors. We characterize delay degradation in the routing structures on FPGAs. The rising and falling del...

To design a routing protocol that saves sensor node energy while meeting the needs of different applications has become a research focus in wireless sensor network. In this paper, we propose Energy-Efficient and Delay-Constrained Routing (EEDCR) protocol, in which delay-sensitive packets are transmitted along the shortest path to minimize their end-to-end delay, while others are sent to the nex...
