Advancements in network technology have led to the emergence of new computing paradigms that challenge established programming practices by employing weak forms of consistency and dynamic forms of

We study absolute and relative keys for XML, and investigate their associated decision problems.

We use a simplified version of the Policy Description Language PDL introduced in (Lobo, Bhatis, & Naqvi 1999) to represent and reason about policies.

The purpose of this paper is to provide insight into a systematic approach to designing the "linear channel" of a repeater for a digital fiber optic communication system.

This paper will apply the theory of Part I to illustrate in detail how the required received optical power in a digital fiber optic repeater varies with the parameters such as the desired error rat

Simulation and measurement show that the robustness of a transmission system to first-order polarization-mode dispersion (PMD) depends on the combination of modulation format and receiver character

We present a data-aided multi-symbol phase estimation scheme that improves the receiver sensitivities of direct-detection optical DQPSK and DQPSK/ASK. Sensitivity improvements of 1.

We propose a method to estimate the amplitude of an unexpected power loss which, leveraging on a calibration, enables the real-time monitoring of a network link.

In the multi-cell environment, the approaches that are suitable for the single cell scenario may cause excessive interference to other cells and become suboptimal.

We discuss advanced direct-detection receiver structures for a variety of optical amplitude- and phase-coded modulation formats, and point at format-specific design trade-offs.
