A review of application of terrestrial laser scanning in building seismic damage analysis

open access: yes地震科学进展, 2023
Terrestrial Laser Scanning (TLS), as an emerging technology, is gradually being applied to various fields such as surveying, and it is the main way to obtain LiDAR high-precision data for ground-based targets.

Towards accurate individual tree parameters estimation in dense forest: optimized coarse-to-fine algorithms for registering UAV and terrestrial LiDAR data

open access: yesGIScience & Remote Sensing, 2023
Accurate quantification of individual tree parameters is vital for precise forest inventory and sustainable forest management. However, in dense forests, terrestrial laser scanning (TLS), which can provide accurate and detailed forest structural ...

Characterization of wavelength tunable lasers for future optical communication systems [PDF]

open access: yes, 2010
The use of tunable lasers (TL) in dense wavelength division multiplexed (DWDM) networks for optical switching, routing and networking has gained a lot of interest in recent years.

Germinal center reactions in tertiary lymphoid structures associate with neoantigen burden, humoral immunity and long-term survivorship in pancreatic cancer

open access: yesOncoImmunology, 2021
Pancreatic ductal adenocarcinoma (PDAC) has traditionally been thought of as an immunologically quiescent tumor type presumably because of a relatively low tumor mutational burden (TMB) and poor responses to checkpoint blockade therapy.

Multi-temporal analysis of morphologic changes applying geomatic techniques. 70 years of torrential activity in the Rebaixader catchment (Central pyrenees)

open access: yesGeomatics, Natural Hazards & Risk, 2019
The monitoring of morphologic changes in high-mountain environments is an important, but complex task. Terrestrial as well as airborne laser scanning (TLS and ALS) and digital photogrammetry (DP) using Unnamed Aerial Vehicle (UAV) can determine recent ...

A review of climatic and vegetation surveys in urban environment with laser scanning: A literature-based analysis [PDF]

open access: yesGeographica Pannonica, 2019
Laser scanning is a promising relatively new technology of land surveying and has different contributions to research areas and practical applications. We performed a review based on query terms in the Scopus database.

Terrestrial Laser Scanning to Detect Liana Impact on Forest Structure [PDF]

open access: yes, 2018
Tropical forests are currently experiencing large-scale structural changes, including an increase in liana abundance and biomass. Higher liana abundance results in reduced tree growth and increased tree mortality, possibly playing an important role in ...

Transit Least Squares: Optimized transit detection algorithm to search for periodic transits of small planets

open access: yes, 2019
We present a new method to detect planetary transits from time-series photometry, the Transit Least Squares (TLS) algorithm. TLS searches for transit-like features while taking the stellar limb darkening and planetary ingress and egress into account.

Low temperature dipolar echo in amorphous dielectrics: Significance of relaxation and decoherence free two level systems

open access: yes, 2012
The nature of dielectric echoes in amorphous solids at low temperatures is investigated. It is shown that at long delay times the echo amplitude is determined by a small subset of two level systems (TLS) having negligible relaxation and decoherence ...

Building Information Modeling (BIM) Utilization for 3D Fiscal Cadastre

open access: yesIndonesian Journal of Geography, 2019
Parcels data in Indonesia are still stored in 2-dimensional (2D) geometry which are integrated with other attribute data, such as the case with the Directorate of Land and Building Tax Indonesia.
