“…35 R-estimators have gained increasing attention in geodetic science. 36,37 Kargoll 38 described an algorithm for computing R-estimates of the parameters of a general linear model with satellite gravity gradiometer data. Duchnowski 39 adapted the theory of R-estimation to the adjustment of leveling networks with homoscedastic observations in the context of deformation analysis.…”

The terrestrial laser scanning technology is increasingly applied in the deformation monitoring of tunnel structures. However, outliers and data gaps in the terrestrial laser scanning point cloud data have a deteriorating effect on the model reconstruction. A traditional remedy is to delete the outliers in advance of the approximation, which could be time- and labor-consuming for large-scale structures. This research focuses on an outlier-resistant and intelligent method for B-spline approximation with a rank (R)-based estimator, and applies to tunnel measurements. The control points of the B-spline model are estimated specifically by means of the R-estimator based on Wilcoxon scores. A comparative study is carried out on rank-based and ordinary least squares methods, where the Hausdorff distance is adopted to analyze quantitatively for the different settings of control point number of B-spline approximation. It is concluded that the proposed method for tunnel profile modeling is robust against outliers and data gaps, computationally convenient, and it does not need to determine extra tuning constants.

“…As the vehicles becoming more and more important in city's life, VANETs put the road for offering services to users on wheels using the flexible vehicle-to-vehicle (V2V) or vehicle-to-infrastructure (V2I) communications [3][4][5]. Recently, with the development of large-scale Intelligent Transportation System (ITS) deployment, infotainment service has become a foreseeable trend in VANETs [6][7][8][9][10][11]. What is more, drivers will be alerted timely with precise information by using of multimedia technologies when there is a dangerous situation or an accident ahead.…”

Content dissemination over vehicular networks is a critical challenge due to its high intermittent connectivity. However, content cache and retrieval by exploiting the information-centric networking (ICN) paradigm did not get much attention. In this paper, in order to improve the efficiency of content retrieval, we propose a novel popularity-aware content caching and retrieving strategy in VANETs named P-CCR, which innovatively considers the ICN perspective into vehicles mobility and vehicular wireless communication in highway scenarios. At the same time, it supports to independently switch the retrieval modes between vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) according to the popularity of contents. Most notably, an actively caching mechanism is proposed in P-CCR, which can be triggered to inform surrounding volunteer vehicles to cache contents requested in a short time. Extensive simulations highlight that P-CCR significantly reduces RTT value and the amount of interest packets, which can lighten network loads and avoid wasting resources.
