Zusammenfassung: A novel measuring method for the battery state is presented to supplement the usual methods on the basis of electrical measurements and computational battery models. Measurement setup and procedure for observing the change in the electrode material during the storage and removal of lithium ions are presented in detail. The ion intercalation of the electrochemical process can be made visible by means of a test cell with a transparent window and continuous image recording and processing. The change in reflectance and color on the surface of a lithium iron phosphate electrode was found to closely correlate with the charge state calculated from cell current. Furthermore, we discovered that an electrochromic marker introduced into the electrode material significantly enhances the optical effect. Observing the electrode allows for the analysis of the ion intercalation within the electrode. The spatially resolved information could be used to determine the parameters of the reaction kinetics and material characteristics. Image recording on optical test cells was used for comparative materials testing in various geometries. The aim is to develop a sensor that can be used in commercial battery cells. For this purpose, preliminary experiments with optical fibers have been conducted. The optical fibers are to be prepared so that the transmitted light interacts with the electrode material, and inserted into the cell structure. This fiber sensor could provide a complementary battery management function to calculate the state-of-charge and as a redundant safety level to avoid critical battery conditions.

Towards a Rigorous Methodology for Measuring Adoption of RPKI Route Validation and Filtering
Sigcomm Computer Communication Review, 48(1):19–27

Zusammenfassung: A proposal to improve routing security---Route Origin Authorization (ROA)---has been standardized. A ROA specifies which network is allowed to announce a set of Internet destinations. While some networks now specify ROAs, little is known about whether other networks check routes they receive against these ROAs, a process known as Route Origin Validation (ROV). Which networks blindly accept invalid routes? Which reject them outright? Which de-preference them if alternatives exist? Recent analysis attempts to use uncontrolled experiments to characterize ROV adoption by comparing valid routes and invalid routes. However, we argue that gaining a solid understanding of ROV adoption is impossible using currently available data sets and techniques. Our measurements suggest that, although some ISPs are not observed using invalid routes in uncontrolled experiments, they are actually using different routes for (non-security) traffic engineering purposes, without performing ROV. We conclude with a description of a controlled, verifiable methodology for measuring ROV and present three ASes that do implement ROV, confirmed by operators.
