The notion of limit condition that we propose is a generalization of the delay condition [1], [2], including the models of the delay circuits, of the C elements of Muller and of the combinational circuits.

Multihop networks must pass messages between source and destination nodes via intermediate links and nodes. Assuming propagation delay is ignored, the mean amount of time the average message stays in a multihop network is directly proportional to the mean distance, in hops, between nodes. Thus, the aggregate link capacity of the network is also directly proportional to this "mean internodal dis...

2D process and device simulators have been used to predict the performance of scaled MOSFETs spanning the 0.35m to 0.07m generations. Requirements for junction depth and channel doping are discussed. Constant-field scaling is assumed. MOSFET drive current remains nearly constant from one generation to the next and most of the performance improvement comes from the decreasing supply voltage. Gat...

Underwater wireless sensor network (UWSN) is a special kind of wireless sensor network which is composed of a large quantity number of wireless sensor nodes deployed in the water. While there are extensive studies on deploy-issue of terrestrial wireless sensor networks (WSN), UWSN has not been paid enough attention due to the challenges of UWSN, such as low available bandwidth, highly varying m...

A framework to adaptively perform delay fault diagnosis is introduced. We propose a methodology to perform diagnosis taking into account the effect of test vector on the propagation delay along a path. An ATPG capable of generating test vectors that cannot be invalidated due to process variations in the submicron technology is used for diagnosis purposes. The proposed framework also has the abi...

Abstmct-The effect that large Propagation delay has on the problem of network access is explored for the infinite population model with success-idle-collision feedback information, where the feedback information suffers a large propagation d&y N. A simple lower bound is given on the PrObeMlity that a packet is not successfully transmitted within N / 2 time units (not including the fomrd propaga...

In this paper we consider the problem of estimating the propagation delays and relative amplitudes of the transmitted signals as well as detecting the data bits in an asynchronous direct-sequence code division multiple access (DS-CDMA) system operating over a fading channel. A subspace based estimator is proposed for estimating the propagation delays. The path gains and data bits are estimated ...

The end-to-end (e2e) stability of Internet routing has been studied for over a decade, focusing on routes and delays. This paper presents a novel technique for uncovering the origins of delay variations by measuring the overlap between delay distribution of probed routes, and how these are affected by route stability. Evaluation is performed using two large scale experiments from 2006 and 2009,...

This paper addresses the lack of reliability within the Swedish rail network by identifying passenger train delay distributions. Arrival delays are analyzed in detail using data provided by the Swedish Transport Administration, covering all train departures and arrivals during 2008 and 2009. The paper identifies vulnerabilities by size, space and time in the network. Our results show that the d...
