Superconducting electrical machine with two part rotor with center shaft capable of handling bending loads

A superconducting electrical machine includes a rotor and a stator. The stator defines a cavity. The rotor is configured to rotate about a longitudinal axis. The rotor is disposed at least partially within the cavity. The rotor includes a shaft configured to rotate with the rotor, a rotor active section including at least a rotor torque tube and a superconductor, and a first re-entrant end attaching the shaft to the rotor active section. At most a threshold fraction of a bending force applied to the shaft is communicated to the rotor active section.

Handling Skewed Emission Distributions in Natural Gas Systems

This work was presented at the American Center for Life Cycle Assessment (ACLCA) LCAXVIII Conference in Fort Collins, CO on September 26, 2018. The presentation showed how NETL's LCA program has gradually improved its methods for uncertainty characterization for upstream natural gas and associated power systems. An objective of uncertainty characterization is to understand the role of system variability without introducing more uncertainty to the data. Non-parametric statistical bootstrapping is one technique for accomplishing this objective and is especially useful for skewed, irregularly-shaped probability distributions. Stochastic modeling is effective at retaining data dependencies, even if specific correlations are not identified.

General Handling Calculations for the Modified Hospital Can

Containers are evaluated using a Monte-Carlo N-Particle transport code (MCNP). The code calculated keff is compared to critical experiment benchmarks to determine a bias. Additional margin of safety is added to the bias to establish an upper subcritical limit (USL). Modeled cases are considered subcritical if the neutron multiplication factor plus two sigma remains below the USL. Net weight limits allow for any amount of fissile/moderator mixture to exist so long as it meets the weight requirement, therefore all mixture types must be evaluated. Cases that exceed the USL must either be controlled against or have justification why that configuration cannot reasonably exist. Current and legacy loadings and container dimensions must be taken into consideration.

Plotting XPS Narrow Scans (and other Data) with MATLAB’s Powerful Plotting Capabilities, 2. An Introduction to Handle Graphics

The graphical representation of numerical data plays a vital role in chemistry, materials science, and every other scientific field. No matter how good your results are, poorly represented data can ultimately make your work confusing. Indeed, with an increase in the amount of data that is being gathered, e.g., by the Materials Genome Initiative, or in X-ray photoelectron spectroscopy (XPS) or time-of-flight secondary ion mass spectrometry (ToF-SIMS) depth profiles, the importance of effectively representing data has increased. Good figures also matter because many researchers will not look at more than the title, abstract, and perhaps a few key figures from a paper.

Device for residue handling minimization with vacuum-assisted separations

A device for collection of residue from separation columns. A manifold provides for multiple sample ports that are fluidly connected to a vacuum port by at least one channel. Residue from the separation columns is pulled through the sample ports, into the channel, and then to the vacuum port. From the vacuum port the residue can be moved, under the force of the vacuum, directly to a drain or to a collection vessel connected with a drain.

Algal Feedstock Logistics and Handling

The project aims to study wet, anaerobic storage to mitigate seasonal variation in algae productivity to reduce the risk of feedstock loos prior to conversion and to study how to enable the storage period to be used to add value to algae biomass without affecting the final fuel's yield or quality. This project will take the approach of engaging in stability research that addresses seasonal variability in production and that which provides opportunities to add value to algae biomass prior to conversion as well as to gain a fundamental understanding of post-harvest algae physiology to support cultivation gains.
