TL;DR: This review paper provides a comprehensive set of design and analysis tools for designing unbiased FIR filters, predictors, and smoothers for slowly varying signals, i.e. signals that can be modeled by low order polynomials.

TL;DR: In this article, the authors used UAV data to generate displacement maps by image correlation techniques, to analyse surface lowering and accumulation processes, and to interpret the geomorphology base on shaded relief images.

TL;DR: In this paper, the Fast On-Orbit Recording of Transient Events (FORTE) derived TEC variabilities on a diurnal cycle, seasonal cycle, 11-year solar cycle, and 27-day solar cycle are compared with the TEC estimates from the Los Alamos ionospheric transfer function implemented with the International Reference Ionosphere model, the GPS-derived TEC maps from NOAA, GPS measurements made at Los AlamOS, and the ionosonde critical frequency data at the closest station, Boulder, Colorado.

TL;DR: A new possible approach to large-scale dimensional metrology based on wireless sensor networks based on a wireless network of optical devices that is portable, fully scalable with respect to dimensions and shapes and easily adaptable to different working environments is presented.
