Analysis of the Blade Boundary-Layer Flow of a Marine Propeller with RANSEJoão Baltazar
In this paper a comparison between RANSE simulations carried out with the k-\omega SST turbulence model and \gamma-Re_\theta transition model, and experimental measurements for marine propeller P4119 is made. The experiments were conducted at the David Taylor Model Basin and comprehended three-dimensional velocity components measurements of the blade boundary-layer and wake using a LDV system in uniform conditions. The present work includes an estimation of the numerical errors that occur in the simulations, analysis of the propeller blade flow, chordwise and radial components of the boundary-layer velocities and boundary-layer characteristics. From this comparison and depending on the selected turbulence inlet quantities, we conclude that the transition model is able to predict the extent of laminar and turbulent regions observed in the experiments.

Evaluating Dust Abatement Potential of Stocking Density Manipulation at Open-...LPE Learning Center
This study evaluated the potential for stocking density manipulation to reduce feedyard dust levels. Researchers blocked pens into control (normal 150 ft2/hd density) and treatment (double density of 75 ft2/hd) groups. Dust sampling found PM10 concentrations, emission fluxes, and emission factors were significantly lower in doubled density pens compared to controls, indicating increased stocking density can effectively reduce dust through manure compaction and moisture retention.

The document describes steps to calculate cable conductor dimensions based on IEC sizes. It first assigns standard cable sizes and calculates diameters using the cable areas. It then assigns cable numbers, sizes, diameters, and areas. Stranding factors are applied based on the number of strands to obtain the conductor outer diameter for different standard stranded cables. The stranding factors are calculated and applied to determine the final conductor diameters.

The document analyzes different geodata resolutions (1m, 5m, 10m) for coverage prediction accuracy in urban, suburban, and rural morphologies. For urban and suburban areas, 5m resolution is recommended as the delta between 1m and 5m predictions is marginal. For rural areas, 10m resolution can be considered as the deltas between 1m and 10m are smaller than in urban/suburban areas. The key factors analyzed are coverage prediction, histograms, statistics, and percentage deltas between resolutions.

3) Details are provided on velocity profiles for fully developed laminar flow in pipes, including the parabolic profile and equations for mean flow velocity. Constants are derived for the laminar flow profile equations.

The document concludes by describing Doosan's joint demonstration project with the Saline Water Conversion Corporation in Saudi Arabia to further develop HT MED technology for Gulf seawater conditions.
1. Sensitivity analysis determines how changes in input parameters impact the output measures of an economic analysis. Parameters like costs, salvage values, and lives can impact measures like net present worth.
2. Three common methods for analyzing sensitivity are: plotting parameter values against output measures, using a pessimistic, most likely, and optimistic estimate for each parameter, and determining the expected value when probabilities of different outcomes are known.
3. The expected value approach sums the product of each possible outcome and its probability to determine the long-run average outcome when variability exists. This allows decisions to account for economic uncertainty.
