Ruiz del Solar, Javier; Palma Amestoy, Rodrigo; Marchant, Román; Parra Tsunekawa, Sebastián Isao; Zegers, Pablo (Elsevier, 2009)A methodology for the analysis and design of fall sequences of robots that minimize joint/articulation injuries, and the damage of valuable body parts is proposed. These fall sequences can be activated/triggered by the ...

Achurra, L. E.; Lacassie Reyes, Juan Pablo; Le Roux, Jacobus; Marquardt, C.; Belmar Urbina, Mauricio; Ruiz del Solar, Javier; Ishman, S. E. (Elsevier, 2009)Manganese nodules recovered from two stratigraphic horizons of Tortonian–Messinian (late Miocene) age in the Bahía Inglesa Formation of north-central Chile were studied using XRD, SEM and geochemical analysis. The dominant ...

Loncomilla, Patricio; Ruiz del Solar, Javier; Martínez, Luz (2016)The main goal of this survey is to present a complete analysis of object recognition methods based on local invariant features from a robotics perspective; a summary which can be used by developers of robot vision applications ...
-
Ruiz del Solar, Javier; Devia, Christ; Loncomilla, Patricio; Concha, Felipe (Springer-Verlag, 2008)In this article, a new approach to offline signature verification, based on a general-purpose wide baseline matching methodology, is proposed. Instead of detecting and matching geometric, signature-dependent features, ...

Jaimes, A.; Ruiz del Solar, Javier; Verschae, Rodrigo; Baeza Yates, Ricardo; Castillo, C.; Yaksic, D.; Davis, E. (Rinton Press, 2004)We propose a methodology to characterize the image contents of a web segment, and we present an analysis of the contents of a segment of the Chilean web (.CL domain). Our framework uses an efficient web-crawling architecture, ...
