The so-called Mohorovičić discontinuity (or Moho) is the interface between the upper mantle and lower crust of the Earth and its determination and characterization is typically based on lithological information, seismicity, and gravity. While lithology and seismic waves suffer for sparsity and non-homogeneous spatial coverage data due to high costs...

Alpine glaciers are strongly suffering the consequences of the temperature rising and monitoring them over long periods is of particular interest for climate change tracking. A wide range of techniques can be successfully applied to survey and monitor glaciers with different spatial and temporal resolutions. However, going back in time to retrace t...

In this paper, three different methods for computing the terrain correction have been compared. The terrain effect has been accounted for by using the standard right parallelepiped closed formula, the spherical tesseroid and the flat tesseroid formulas. Particularly, the flat tesseroid approximation is obtained by flattening the top and the bottom...

One of the main benefits of Building Information Modelling is the capability of improving the decision-making process thanks performing what-if tests on digital twins of the building to be realized. Pairing BIM models to Building Energy Models allows designers to determine in advance the energy consumption of the building, improving sustainability...

The building sector plays a central role in addressing the problem of global energy consumption. Therefore, effective design measures need to be taken to ensure efficient usage and management of new structures. The challenging task for designers is to reduce energy demands while maintaining a high-quality indoor environment and low costs of constru...

The definition of a common global vertical coordinate system is nowadays one of the key points in Geodesy. With the advent of GNSS, a coherent global height has been made available to users. The ellipsoidal height can be obtained with respect to a given geocentric ellipsoid in a fast and precise way using GNSS techniques. On the other hand, the tra...

It is incontrovertible that an exchange of files is essentially required at several stages of the workflow in the architecture, engineering, and construction (AEC) industry. Therefore, investigating and detecting the capabilities/inabilities of building information modeling (BIM) software packages with respect to interoperability can be informative...

This paper investigates quality management (QM) during the execution phase of structural elements by proposing, developing, and testing a complete framework by integrating building information modeling (BIM) and augmented reality (AR) technology. QM during execution is boosted by BIM–AR integration through a dedicated web-based system aimed at redu...

In this study the cupola of San Gaudenzio’s Basilica in Novara, Italy, has been monitored by using two low-cost GNSS receivers located on the East and West side of the spire. Time series of daily solutions for an observation period of about one year have been collected and interpolated by cubic splines. The minimum description length criterion has...

This work aims at presenting the use of new technologies in the field of forensic engineering. In particular, the use of UAV photogrammetry and laser scanning is compared with the traditional methods of surveying an accident site. In this framework, surveys must be carried out promptly, executed in a short time and performed so that the greatest po...

A pure GNSS navigation is often unreliable in urban areas because of the presence of obstructions, thus preventing a correct reception of the satellite signal. The bridging between GNSS outages, as well as the vehicle attitude reconstruction, can be recovered by using complementary information, such as visual data acquired by RGB-D or RGB cameras....

In the last decades, low-cost GNSS receivers have been widely used for navigation purposes. Some of them deliver also raw data, allowing for a more sophisticated processing, such as the double-difference approach, and therefore a more accurate positioning, typically at the decimeter level. However, these accuracies can be generally achieved only wi...

Global Navigation Satellite Systems (GNSS) receivers are nowadays commonly used in monitoring applications, e.g., in estimating crustal and infrastructure displacements. This is basically due to the recent improvements in GNSS instruments and methodologies that allow high-precision positioning, 24 h availability and semiautomatic data processing. I...

National geoid models are frequently used in engineering applications to transform GNSS derived ellipsoidal heights into orthometric heights. The establishment of a unique International Height Reference System (IHRS) among neighboring countries requires the verification of the consistency between national geoids. The choice of different reference t...

The combination of altimeter data and gravity allows an effective estimation of the Mean Dynamic Topography (MDT) at sea. The MDT allows then estimating the oceanic currents, a crucial information in hydrological analysis and oceanographic studies. This is of particular interest in closed seas, such as the Mediterranean Sea, due to the impact that...
Article
Collocation has been widely applied in geodesy for estimating the gravity field of the Earth both locally and globally. Particularly, this is the standard geodetic method used to combine all the available data to get an integrated estimate of any functional of the anomalous potential T. The key point of the method is the definition of proper covari...

Non Local Means (NLM) filtering is a well-known image-processing algorithm for random noise attenuation. It is based on the assumption that coherent and non-coherent features can be identified and separated using a measure of similarity between adjacent samples. In this paper we review and extend previous work on the use of NLM in seismic data proc...

Collocation approach has been applied to get a global Moho model in spherical approximation based on a GOCE geopotential model. A simple single layer model, with known density contrast, has been considered and a linearized relationship between the spherical harmonic coefficients of the anomalous potential and those of the Moho depth has been derive...

When the results of geophysical models are compared with data, the uncertainties of the model are typically disregarded. This paper proposes a method for defining the uncertainty of a geophysical model based on a numerical procedure that estimates the empirical auto- and cross-covariances of model-estimated quantities. These empirical values are th...

We have measured the speed of muon neutrinos with the Borexino detector using short-bunch CNGS beams. The final result for the difference in time-of-flight between an E=17 GeV muon neutrino and a particle moving at the speed of light in vacuum is δt=0.8±0.7 stat±2.9 sys ns, well consistent with zero.

During May 2012, the CERN-CNGS neutrino beam has been operated for two weeks for a total of ~1.8 × 1017 p.o.t., with the proton beam made of bunches, few ns wide and separated by 100 ns. This beam structure allows a very accurate time of flight measurement of neutrinos from CERN to LNGS on an event-by-event basis. Both the ICARUS-T600 PMT-DAQ and t...

This project amis at a through monitoring of the evolution of the Belvedere Glacier, a debris-covered glacier in the Italian Alps. The project involves the use photogrammetry to extensively derive the 3D glacier evolution, with different spacial (10 cm - 1m) and temporal resolution (from multi-annual to daily) and with different platforms (UAVs, aerial photogrammetry, Terrestrial time-lapse cameras). Since 2015, annual UAV-photogrammetric surveys allowed for deriving annual average glacier flow and volume variations (Ioli et al, 2022). Historical (analog) aerial images were processed with a modern photogrammetric approach to derive the glacier 3D morphology in 1977, 1991 and 2001 (De Gaetani et al., 2021). Currently, two time-lapse cameras, permanently installed at the NW glacier terminus, are being used to derive daily 3D glacier movements and changes in the ice structures (such as ice falls and claving events).
