Dynamic legged locomotion entails navigating unstructured terrain at high speed. The discontinuous foot-fall patterns and flight phases, which are pivotal for its unrivaled mobility, introduce large impulses and extended free-falls that serve to destabilize motion estimation. In a nod to biological systems, visual information, in the form of optical flow, is used with a hybrid estimator tuned t...

This paper proposes an efficient direction of departure (DOD) and arrival (DOA) estimation method for multi-input multi-output (MIMO) systems. For uncorrelated scenarios, the redundancy covariance matrix is first exploited by establishing its concise representation through reduction, which transforms original large-size into a smaller-size without loss useful angle information. Then, resulting ...

Introduction: Volumetric T1 mapping using two variable flip angle (VFA) acquisitions has become a popular clinical tool for T1 estimation due to short scan times and ease of implementation. The conventional approach to flip angle selection has been based on maximization of the signaldynamic range (S-DR) product for a single T1 value of interest (typically ≤ 1000 ms), with estimation accuracy an...

Mechanical machining processes are common manufacturing strategies to re-shape materials to desired specification. The mechanistic approach has revealed the mechanics of the machining processes with various parameters determined. The aim of this work is to investigate the impact of swept angle optimization and their influence on the specific cutting energy in milling AISI 1045 steel alloy. This...
