    • Delaunay based algorithm for finding polygonal voids in planar point sets 
      Alonso, R.; Ojeda, J.; Hitschfeld Kahler, Nancy; Hervías-Caimapo, Carlos; Campusano Brown, Luis (Elsevier, 2018)
      This paper presents a new algorithm to find under-dense regions called voids inside a 2D point set. The algorithm starts from terminal-edges (local longest-edges) in a Delaunay triangulation and builds the largest possible ...
    • Miscanti-1: Human occupation during the arid Mid-Holocene event in the high-altitude lakes of the Atacama ... 
      Nuñez Atencio, Lautaro; González Loyola, Rodrigo Alejandro; Cartajena, Isabel; Lopez, Patricio; Santander, Boris; Maldonado, Antonio; de Souza, Patricio; Carrasco, Carlos (Pergamon-Elsevier Science LTD, 2018)
      This paper presents an interdisciplinary study of the Miscanti-1 archaeological site, located in the Holocene terrace deposits accumulated on the eastern margin of Miscanti Lake (4120 m.a.s.1.), northern Chile (23.7 degrees ...
    • Radiation damage effects in space-borne CCD detectors operated in TDI mode 
      Terrazas Vargas, Juan; Corcione, L.; Lattanzi, M.G.; Gai, M. (IOP Publishing, 2017-07-01)
      We evaluate the astrometric and photometric implications of a series of laboratory tests conducted to study the effects of radiation damage caused by solar protons in space-borne charge coupled devices (CCDs). The photometric ...
    • Short time-scale variability in the Faint Sky Variability Survey 
      Morales Rueda, L.; Groot, P. J.; Augusteijn, T.; Nelemans, G.; Vreeswijk, Paul M.; Besselaar, E. J. M. van den (Blackwell, 2006)
      We present the V-band variability analysis of the point sources in the Faint Sky Variability Survey on time-scales from 24 min to tens of days. We find that about one per cent of the point sources down to V = 24 are ...
    • Socio-economic and geographic profiling of crime in Chile 
      Rivera Cayupi, Jorge; Núñez Errázuriz, Javier; Gutiérrez, Mauro (Naciones Unidas, 2009)
      Many empirical studies of crime assume that victims and perpetrators live in a single geographical unit, the implication being that the socio-economic characteristics of victims’ places of residence can be treated as ...
    • Statistically-based methodology for revealing real contagion trends and correcting delay-induced errors in ... 
      Contreras, Sebastián; Biron Lattes, Juan Pablo; Villavicencio, Andrés; Medina Ortiz, David; Llanovarced Kawles, Nyna Koyllor; Olivera Nappa, Álvaro (Elsevier, 2020)
      COVID-19 pandemic has reshaped our world in a timescale much shorter than what we can understand. Particularities of SARS-CoV-2, such as its persistence in surfaces and the lack of a curative treatment or vaccine against ...
