Sampling strategies for forest aerial detection survey in Colorado
… my dissertation was to identify an appropriate sampling strategies to archive good estimates of total area damaged, to decrease survey cost, and to increase safety by reducing the amount of flights. To approach this goal, four sample designs for estimating total area damaged caused by various …

Cellar Dwellers: Historic Feature Sampling Strategies in Ontario Commercial Archaeology
This study will explore the logics of a particular practice in the commercial archaeology industry in Ontario. This practice is embodied within the standards and guidelines the provincial governing body released in 2011 for commercial archaeology in Ontario. One specific standard directs excavation …

Adaptive observations : idealized sampling strategies for improving numerical weather prediction
… network. In this study, we explore observation strategies in a simulated idealized system with a three-dimensional quasi-geostrophic model and a realistic data assimilation scheme. Several issues are addressed, including whether adapting observations has potential to improve forecasts, how …

Novel Mass Spectrometric and Sampling Strategies for Investigating Neuropeptide Processing and Distribution
… In some instances, however, alternative sampling approaches such as microseparation with MALDI MS detection are necessary to pre-concentrate and partially purify neuropeptides and to reduce ionization suppression effects. Here we describe the use of capillary electrophoresis (CE) coupled …

Sampling Strategies for Characterization of Neuropeptides Using Mass Spectrometry and Functional Implications Into Cell -Cell Signaling
The peptides with roles in the development of the pituitary were analyzed using transgenic mice. Hes1 KO is a genetically modified mouse that lives only e18.5 (embryonic days). Anterior pituitaries of Hes1 null mice exhibit hypoplasia due to increased cell death and reduced proliferation and in the …

Sampling strategies for characterization of neuropeptides using mass spectrometry and functional implications into cell-cell signaling
… there are developed different analytical strategies to discover and characterize mammalian brain peptides using small amount of tissues. The magnocellular neurons of rat supraoptic nucleus in tissue and cell culture served as the main model to study neuropeptides, in addition to …

Optimizing wastewater treatment sampling strategies through Markov Chain Monte Carlo Bayesian inference in Activated Sludge Model No. 3
… to sparse year-long programmes with weekly sampling were systematically evaluated, controlling measurement noise and system configuration. Three inference configurations were compared across all monitoring regimes: structured workflow employing sensitivity screening, identifiability …

Bayesian modelling and sampling strategies for ordering and clustering problems with a focus on next-generation sequencing data
… two parts focus on the development of models and sampling strategies specifically tailored for next-generation sequencing data. Most high-throughput measurements for single-cell data are destructive, resulting in the loss of longitudinal information. I developed a new, Bayesian, way of …

Toward enhancing metaheuristic optimization algorithms using center-based sampling strategies for solving single- and multi- objective large-scale problems
… metaheuristic algorithms have used stochastic strategies in their initialization as well as during the new candidate solution generation process where there is no a priori knowledge about the solution, which is a common assumption for any black-box optimization problem. In recent years, …

Investigations of Colorado potato beetle [Leptinotarsa decemlineata (Say)] pest management including: sampling strategies for insecticide resistance detection, development of a knowledge-based expert system and the physiology of cold tolerance
… beetle in the entire field. The probability of sampling potato beetles from one location which differed in mean mortality (P ≤ 0.05) from individuals collected in another location within the same field decreased as the number of locations sampled increased (i.e., the probability is 0.12 if three …

Leveraging Gaussian Process Sampling for Sensitivity Analysis and Optimization in Engineering Design
… challenge. GPs inherently facilitate efficient sampling strategies, enabling informed decision-making under uncertainty by extracting information from a subset of potential functions for the model of interest. Despite their widespread use in machine learning and scientific computing, and the …

Accelerating Physically-Based Light Transport Algorithms
… and introduce intelligent importance sampling strategies which adapt themselves to image content in an unbiased manner. We demonstrate that these techniques offer substantial improvement over the prior art and offer sufficient generality to be deployed in many path tracing-based light …

Exploring optimising strategies for sampling air-sea carbon dioxide flux in the southern ocean
… undertaken to investigate the optimization of sampling strategies for returning low-uncertainty sea-air CO₂ flux measurements in the Southern Ocean. Replicating Lenton et al. (2006) using the ORCA2/PISCES ocean biological model shows that sampling 4 times a year, every 2⁰ in latitude and every …

Use of numerical simulations to investigate the performance of a virtual acoustic Doppler current profiler in characterizing flow
… research investigates the spatial and temporal sampling strategies of a virtual acoustic Doppler current profiler (ADCP) in characterizing flow fields and mean velocity profiles from stationary and moving platforms. This was accomplished in part using a data set with high temporal and spatial …

Developing a strategy for identifying genetically important animals
… in a gene bank is a complex issue. A suboptimal sampling strategy can lead to biased results, the need for additional sampling, and can be costly. When using public funds (e.g., federal grant or federal appropriations) or member fees (e.g., breed association funds), we have a responsibility to …
