Variation in the management of Ductal RC046 Carcinoma In Situ (DCIS) of the breast occur at both national and international levels.The aim of this study is to determine the degree of, and reasons behind, this variation in the workup and treatment of DCIS among Canadian surgeons.We developed a 35-question survey involving the pre-, peri, and post-op
Frequency is an important factor influencing the fatigue behavior.Regarding to the dwell fatigue, it corresponds to the effect of rise and fall time, which is also an important issue especially for the safety evaluation of structure parts under dwell fatigue loading, such as the engines of aircrafts and the pressure hulls of deep-sea submersibles.I
A fading mechanism during Heart Wooden Plaque casting of treated Al-B-Sr master alloys in an aluminium-silicon cast alloy was investigated.Two different master alloys, the Al-3%B-3%Sr and Al-4%B-1%Sr were demonstrated for the efficiency test both grain refinement and modification microstructure.From experimental result, the addition of Al-3%B-3%Sr
The 3D maps are used for self-positioning estimation and path planning for the autonomous navigation of robots in urban areas.This paper presents a framework that generates globally consistent 3D maps from the pose graph of existing simultaneous localization and mapping (SLAM) methods.Our approach corrects a pose graph by performing a 3D alignment
