Study: AI models fail to reproduce human judgements about rule violations（图）
人工智能模型 通用数据收集 机器学习模型 决策
2023/6/20
In an effort to improve fairness or reduce backlogs, machine-learning models are sometimes designed to mimic human decision making, such as deciding whether social media posts violate toxic content po...

Penn Researchers Establish Universal Signature Fundamental Glassy Materials Fail
2017/12/18
Dropping a smartphone on its glass screen, which is made of atoms jammed together with no discernible order, could result in it shattering. Unlike metals and other crystalline materials, glass and man...
Penn Engineers Show How “Perfect” Materials Begin to Fail
Penn Engineers Perfect Materials Begin to Fail
2015/6/18
Crystalline materials have atoms that are neatly lined up in a repeating pattern. When they break, that failure tends to start at a defect, or a place where the pattern is disrupted. But how do defect...
Penn Researchers Show Commonalities in How Different Glassy Materials Fail
Different Glassy Materials Fail
2014/12/30
Glass is mysterious. It is a broad class of materials that extends well beyond the everyday window pane, but one thing that these disparate glasses seem to have in common is that they have nothing in ...

This paper demonstrates the effectiveness of outer-cover of pressure vessel in order to prevent risk scenario by brittle fracture. The Fail-Safe design introducing the concept of a standby redundant s...
The purpose of this study was to illustrate that a systems approach to transit safety
can be used to develop a methodology to fail-safe or mistake-proof paratransit
operations. The fail-safe methodo...
Thick Film Fail-Safe Resistors
Thick Film Fail-Safe Resistors composition material a resistive path
2010/12/27
The investigations of low resistance thick film fail-safe resistors are presented. Particularly the shape of a resistive path; the temperature of the central part of the resistor while increasing the ...
