The benefit of 3D laser scanning technology in the generation and calibration of FEM models for health assessment of concrete structures

Yang, Hao; Xu, Xiangyang; Neumann, Ingo (Basel : MDPI AG, 2014)

Terrestrial laser scanning technology (TLS) is a new technique for quickly getting three-dimensional information. In this paper we research the health assessment of concrete structures with a Finite Element Method (FEM) ...
A framework based on reference data with superordinate accuracy for the quality analysis of terrestrial laser scanning-based multi-sensor-systems

Stenz, Ulrich; Hartmann, Jens; Paffenholz, Jens-André; Neumann, Ingo (Basel : MDPI AG, 2017)

Terrestrial laser scanning (TLS) is an efficient solution to collect large-scale data. The efficiency can be increased by combining TLS with additional sensors in a TLS-based multi-sensorsystem (MSS). The uncertainty of ...
Influence of the cutting tool compliance on the workpiece surface shape in face milling of workpiece compounds

Denkena, Berend; Hasselberg, E. (Amsterdam : Elsevier, 2015)

A currently common method to design high-performance workpieces is to combine two or more materials to one compound. In this way, workpieces can be composed of the most qualified materials according to local loads. When ...
Marker-free identification of turned, ground and deep rolled workpieces using wavelet transformation

Breidenstein, Bernd; Wichmann, Marcel; Voelker, Hendrik (Amsterdam [u.a.] : Elsevier, 2023)

This paper presents a marker-free component identification of cylindrical workpieces produced by the manufacturing processes turning, grinding and deep rolling. The position of unique features from a 2-D profile in the 3-D ...
Point-based and model-based geolocation analysis of airborne laser scanning data

Sefercik, Umut Gunes; Buyuksalih, Gurcan; Jacobsen, Karsten; Alkan, Mehmet (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)

Airborne laser scanning (ALS) is one of the most effective remote sensing technologies providing precise three-dimensional (3-D) dense point clouds. A large-size ALS digital surface model (DSM) covering the whole Istanbul ...
Polarisations-FTIR-Spektroskopie und SPA-LEED zur Wechselwirkung von Schwefeldioxid mit den Oberflächen CsF(100), NaCl(100), MgO(100) und MgO(110)

Henseler, Heiner (Hannover : Universität, 1998)

Terrestrial laser scanning technology for deformation monitoring and surface modeling of arch structures

Yang, Hao; Omidalizarandi, Mohammad; Xu, Xiangyang; Neumann, Ingo (London : Elsevier Ltd., 2017)

Terrestrial laser scanning (TLS) is capable to be a reliable deformation monitoring device with high-precision for concrete composite structures. Measurements based on TLS for an arch structure with monotonic loading is ...
TLS-based composite structure deformation analysis validated with laser tracker

Xu, Xiangyang; Bureick, Johannes; Yang, Hao; Neumann, Ingo (Amsterdam : Elsevier, 2017)

This paper focuses on the adjustment of B-spline approximation to terrestrial laser scanning (TLS) data and its contribution to deformation analysis of composite arched structures. The deformation of an arch structure under ...
