Insight into best practices: a review of long-term monitoring of the rocky intertidal zone of the Northeast Pacific Coast

Frontiers in Marine Science, 2023
On the shores of the Northeast Pacific Coast, research programs have monitored the rocky intertidal zone for multiple decades across thousands of kilometers, ranking among the longest-term and largest-scale ecological monitoring programs in the world ...

A design methodology to enable sampling PLLs to synthesise fractional-N frequencies [PDF]

, 2011
A novel design methodology is proposed to enable sampling phase-locked loops (SPLL) to synthesise fractional-N frequencies. To date, SPLL can only generate integer-N frequencies.

Sparse Polynomial Chaos Expansions via Compressed Sensing and D-optimal Design

, 2017
In the field of uncertainty quantification, sparse polynomial chaos (PC) expansions are commonly used by researchers for a variety of purposes, such as surrogate modeling. Ideas from compressed sensing may be employed to exploit this sparsity in order to

The Use of Sheep Movement Data to Inform Design and Interpretation of Slaughterhouse-Based Surveillance Activities

Frontiers in Veterinary Science, 2020
The design of surveillance strategies is often a compromise between science, feasibility, and available resources, especially when sampling is based at fixed locations, such as slaughter-houses.

The Network Nullspace Property for Compressed Sensing of Big Data over Networks

, 2018
We present a novel condition, which we term the net- work nullspace property, which ensures accurate recovery of graph signals representing massive network-structured datasets from few signal values.

A Near-Optimal Sampling Strategy for Sparse Recovery of Polynomial Chaos Expansions

, 2017
Compressive sampling has become a widely used approach to construct polynomial chaos surrogates when the number of available simulation samples is limited.
