Desenvolupament d'una draga per al mostreig de sòls marins

A l'empresa PRAESENTIS S.L. se li proposà la construcció d'una draga per utilitzar-la en el mostreig de sòls marins en expedicions científiques a mar obert. Segons les especificacions del projecte, la draga resultant haurà de ser capaç de recollir mostres d'una capacitat d'entre 60 i 80 l. amb una profunditat de cavat de fins a 20 cm., i haurà de poder assolir profunditats de treball de fins a 500 m. per sota el nivell del mar. El tipus de sòl en el qual es treballarà és de tipus arenós. La draga projectada és un mecanisme basat en una pala bivalva activada per un cilindre hidràulic que utilitza com a bancada una estructura que a l'hora fa la funció de xassís

Modeling object identification and tracking errors on image-based safety assessment of earthmoving operations

Object identification and tracking have become critical for automated on-site construction safety assessment. The primary objective of this paper is to present the development of a testbed to analyze the impact of object identification and tracking errors caused by data collection devices and algorithms used for safety assessment. The testbed models workspaces for earthmoving operations and simulates safety-related violations, including speed limit violations, access violations to dangerous areas, and close proximity violations between heavy machinery. Three different cases were analyzed based on actual earthmoving operations conducted at a limestone quarry. Using the testbed, the impacts of device and algorithm errors were investigated for safety planning purposes.
