In this study, a multilayer composite rolling model consisting of a rolling wheel, a protective layer, a GCL, and a support layer was constructed by the discrete element method (DEM).Soil compaction and gravel migration, and their effects on the GCL, were analyzed from a fine viewpoint, and three key indexes for the safety assessment of the GCL wer
This paper is focused on the design of a mobile robot whose objective is to apply thermal insulation spray in underfloor voids, to improve the energy efficiency of buildings.Solving robustly the mapping and localization problems is crucial to achieve a high degree of autonomy during the development of this task.Nevertheless, underfloor voids consti
A low-cost and planar heterogeneously-integrated 340-GHz THz imager is proposed for lensless THz imaging applications.The proposed THz imager is composed of a $16 imes 16$ antenna array realized in an integrated-passive-device (IPD) technology, an IPD-to-CMOS THz interconnect, and a power detector implemented in a 0.18- $mu ext{m}$ CMOS technology
