The PRISM4 (mid-Piacenzian) palaeoenvironmental reconstruction [PDF]
, 2016 The mid-Piacenzian is known as a period of relative warmth when compared to the present day. A comprehensive understanding of conditions during the Piacenzian serves as both a conceptual model and a source for boundary conditions and means of ...

On-Line Flatness Measurement in the Steelmaking Industry
Sensors, 2013 Shape is a key characteristic to determine the quality of outgoing flat-rolled products in the steel industry. It is greatly influenced by flatness, a feature to describe how the surface of a rolled product approaches a plane.

Markerless Real-Time Garment Retexturing From Monocular 3D Reconstruction [PDF]
, 2011 We present a fusion of augmented reality (AR) and virtual try on (VTO) that incorporates sparse 3D point recovery by exploiting distance constraints based on 2D point correspondences between a deformed texture in monocular video and a reference texture ...

Projective Reconstruction of Surfaces of Revolution [PDF]
, 2003 This paper addresses the problem of recovering the generating curve of a surface of revolution from a single uncalibrated perspective view, based solely on the object’s outline and two (partly) visible cross-sections. Without calibration of the camera’s internal parameters such recovery is only possible up to a particular transformation of the true ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
