We Should Have Already Had This: The Lithium-Ion Battery With Built-In Fire Suppression

On October 22, 2020, yesterday, Dexter Johnson posted The Lithium-Ion Battery With Built-In Fire Suppression. Within this topic, Dexter Johnson regards a Stanford University research team and the SLAC National Accelerator Laboratory (its former name was the Stanford Linear Accelerator Center[1]). Johnson stated:Now [Yi] Cui and his research team, in collaboration with SLAC National Accelerator Laboratory, have offered some exciting new capabilities for lithium-ion batteries based around a new polymer material they are using in the current collectors for them. The researchers claim this new design to current collectors increases efficiency in Li-ion batteries and reduces the risk of fires associated with these batteries.[2]Johnson was saying this: fires are a current Li-ion battery threat that has been realized, but a new design can secure client use-case safety, and this required this battery redesigned. As this technology approaches marketplace entry points, this shall confront Li-io…

A cutting-plane method for contiguity-constrained spatial aggregation

A Cutting Plane Method for a Special AggregationOn November 28, 2017 AD, the Institute of Geodesy and Geoinformation, University of Bonn, Germany accepted an article: by Johannes Oehrlein and Jan-Henrik Haunert, a cutting-plane method for contiguity-constrained spatial aggregation (link).

Planar Subdivisions are Geographic Space StructuresOehrlein and Haunert wrote that planar subdivisions are regular 'geographic space' structures. Oehrlein and Haunert used the same integer linear programs, but the constraints ensured contiguity differences. Next, Oehrlein and Haunert adapted a Shirabe model: on spatial unit allocation. After that, Oehrlein and Haunert wrote: area aggregation is an important map-generalization step; but it contains line simplication, selection, and displacement. Further, the cutting-plane methodOehrlein and Haunert used is a growth: on the ILP basis, the method parts are Objective, Constraints, and an exponent constraint number called contiguity constraints.
