  The stress response of ammonia-oxidizing bacteria (AOB) to oxygen deprivation limits AOB growth and leads to different nitrification pathways that cause the release of greenhouse gases. Measuring the stress response of AOB ...
• Deformation analysis using B-spline surface with correlated terrestrial laser scanner observations-a bridge under load 

  Kermarrec, Gaël; Kargoll, Boris; Alkhatib, Hamza (Basel : MDPI AG, 2020)

  The choice of an appropriate metric is mandatory to perform deformation analysis between two point clouds (PC)-the distance has to be trustworthy and, simultaneously, robust against measurement noise, which may be correlated ...
• On estimating the hurst parameter from least-squares residuals. Case study: Correlated terrestrial laser scanner range noise 

  Kermarrec, Gaël (Basel : MDPI AG, 2020)

  Many signals appear fractal and have self-similarity over a large range of their power spectral densities. They can be described by so-called Hermite processes, among which the first order one is called fractional Brownian ...
