Tracking battery state-of-charge in a continuous use off-grid electricity system [PDF]

open access: yes, 2013
The growing importance of batteries in the delivery of primary energy, for example in electric vehicles and isolated off-grid electricity systems, has added weight to the demand for simple and reliable measures of a battery’s remaining stored energy at ...

FMI Compliant Approach to Investigate the Impact of Communication to Islanded Microgrid Secondary Control

open access: yes, 2017
In multi-master islanded microgrids, the inverter controllers need to share the signals and to coordinate, in either centralized or distributed way, in order to operate properly and to assure a good functionality of the grid.

Photon Avalanching Nanoparticles: The Next Generation of Upconverting Nanomaterials?

open access: yesAdvanced Functional Materials, EarlyView.
This Perspective outlines the mechanistic foundations that enable photon‐avalanche (PA) behavior in lanthanide nanomaterials and contrasts them with emerging application spaces and forward‐looking design strategies. By bridging threshold engineering, energy‐transfer dynamics, and materials engineering, we provide a coherent roadmap for advancing the ...

Memory-based parallel data output controller [PDF]

open access: yes, 1984
A memory-based parallel data output controller employs associative memories and memory mapping to decommutate multiple channels of telemetry data. The output controller contains a random access memory (RAM) which has at least as many address locations as

One Leg Control Strategy in Single-Phase Five-Level Inverter

open access: yes2019 International Symposium on Electrical and Electronics Engineering (ISEE), 2019
The use of power inverter technology with low harmonics content is rapidly growing. For decades, researchers have conducted investigations to minimize its harmonics content, leading to the creation of a five-level inverter.

BACH, a Bayesian Optimization Protocol for Accurate Coarse‐Grained Parameterization of Organic Liquids

open access: yesAdvanced Functional Materials, EarlyView.
We present a fully automated Bayesian optimization (BO) protocol for the parameterization of nonbonded interactions in coarse‐grain CG force fields (BACH). Using experimental thermophysical data, we apply the protocol to a broad range of liquids, spanning linear, branched, and unsaturated hydrocarbons, esters, triglycerides, and water.

Amyloidogenic Peptide Fragments Designed From Bacterial Collagen‐like Proteins Form Hydrogel

open access: yesAdvanced Functional Materials, EarlyView.
This study identified amyloidogenic sequence motifs in bacterial collagen‐like proteins and exploited these to design peptides that self‐assemble into β‐sheet fibers and form hydrogels. One hydrogel supported healthy fibroblast growth, showing promise for biocompatible materials. Our work demonstrates that bacterial sequences can be harnessed to create

Digital interface for bi-directional communication between a computer and a peripheral device [PDF]

open access: yes, 1984
For transmission of data from the computer to the peripheral, the computer initially clears a flipflop which provides a select signal to a multiplexer.
