Structural Strength and Fatigue Strength Analysis of Roller Arm

open access: yesAcademic Journal of Science and Technology, 2023
The cone reamer is used for underhole reaming, mainly through the impact crushing and cutting of teeth to complete rock breaking, easy to produce vibration. At the same time, the underground topography is complex and rock materials are changing. Therefore, the force of the cone reamer is complex and easy to damage.

ROSETTA lander Philae – soil strength analysis

open access: yesIcarus, 2016
Abstract The landing of Philae, the lander of ESA's ROSETTA-mission, on November 12th 2014 on Comet 67P/Churyumov–Gerasimenko, was planned as a descent with passive landing activating a damper system and anchoring by harpoons at touch-down. The lander was not fixed to the ground at touch-down due to failing harpoons.

Password Strength: An Empirical Analysis

open access: yes2010 Proceedings IEEE INFOCOM, 2010
It is a well known fact that user-chosen passwords are somewhat predictable: by using tools such as dictionaries or probabilistic models, attackers and password recovery tools can drastically reduce the number of attempts needed to guess a password. Quite surprisingly, however, existing literature does not provide a satisfying answer to the following ...
