Tracking and back‐tracking [PDF]
Progress in Photovoltaics: Research and Applications, 2011 AbstractThis paper presents a review of back‐tracking geometry not only for single axis but also for two‐axis tracking and analyses the corresponding energy gains. It compares the different back‐tracking strategies with the ideal tracking in terms of energy yield concluding, on the one hand, that back‐tracking is more useful for single horizontal axis ...

ESAIM: Control, Optimisation and Calculus of Variations, 2004 Summary: The problem of invariant output tracking is considered: given a control system admitting a symmetry group \(G\), design a feedback such that the closed-loop system tracks a desired output reference and is invariant under the action of \(G\). Invariant output errors are defined as a set of scalar invariants of \(G\); they are calculated with ...

Follow the Data! A Strategy for Tracing Infrastructural Power
Media and Communication, 2023 Recalling the well-known strategy of “following the money” when investigating the underlying power structures and business models of legacy media, this article argues that studies of digital political economies can benefit instead from following the data.

A novel method for estimating myocardial strain: assessment of deformation tracking against reference magnetic resonance methods in healthy volunteers [PDF]
, 2016 We developed a novel method for tracking myocardial deformation using cardiac magnetic resonance (CMR) cine imaging. We hypothesised that circumferential strain using deformation-tracking has comparable diagnostic performance to a validated method ...

Integrated design of ranging and DOR signal for China's deep space navigation
Open Astronomy, 2022 An integrated ranging and differential one-way range (DOR) signal design is implemented. The design utilizes the regenerative pseudo-noise ranging scheme and one pair of dedicated DOR tones for the deep space United X Band system.

On track to tenure‐track [PDF]
EMBO reports, 2009 A former South American politician once quipped that even a local election in his country resulted in more casualties than a revolution in Germany. His comments were not intended to address questionable political campaign techniques, but rather to comment on the inability of Germans to stage proper revolutions.
