Sensors and mathematical models have been used since the 1990's to assess the health of systems and diagnose anomalous behavior. The advent of the Internet of Things (IoT) increases the range of assets on which data can be collected cost ef...
Maintenance Costs and Advanced Maintenance Techniques in Manufacturing Machinery: Survey and Analysis [0.03%]
制造业机械的维护成本及先进维修技术：调研与分析
Douglas Thomas,Brian Weiss
Douglas Thomas
The costs/benefits associated with investing in advanced maintenance techniques is not well understood. Using data collected from manufacturers, we estimate the national losses due to inadequate maintenance and make comparisons between thos...
Long-Term Modeling and Monitoring of Neuromusculoskeletal System Performance Using Tattoo-Like EMG Sensors [0.03%]
基于纹身式的EMG传感器的神经肌肉骨骼系统长期建模与监测方法研究

Various factors are responsible for injuries that occur in the U.S. Army soldiers. In particular, rucksack load carriage equipment influences the stability of the lower extremities and possibly affects gait balance. The objective of this in...
Measurement and Evaluation for Prognostics and Health Management (PHM) for Manufacturing Operations - Summary of an Interactive Workshop Highlighting PHM Trends [0.03%]
制造操作的预测和健康管理（PHM）测量与评估交互式研讨会总结：关注PHM新趋势
Brian A Weiss,Michael P Brundage
Brian A Weiss
Personnel from the National Institute of Standards and Technology (NIST) organized and led a Measurement and Evaluation for Prognostics and Health Management for Manufacturing Operations (ME4PHM) workshop at the 2019 Annual Conference of th...
Verification of Prognostic Algorithms to Predict Remaining Flying Time for Electric Unmanned Vehicles [0.03%]
电动无人驾驶车辆剩余飞行时间预测的预报算法验证方法研究

Because valves control many critical operations, they are prime candidates for deployment of prognostic algorithms. But, similar to the situation with most other components, examples of failures experienced in the field are hard to come by....
A Computationally-Efficient Probabilistic Approach to Model-Based Damage Diagnosis [0.03%]
一种计算高效的基于模型的损伤识别概率方法
James E Warner,Geoffrey F Bomarito,Jacob D Hochhalter et al.
James E Warner et al.
This work presents a computationally-efficient, probabilistic approach to model-based damage diagnosis. Given measurement data, probability distributions of unknown damage parameters are estimated using Bayesian inference and Markov chain M...
Effects of Obesity and Fall Risk on Gait and Posture of Community-Dwelling Older Adults [0.03%]
肥胖和跌倒风险对社区居住老年人步态和姿势的影响
Thurmon E Lockhart,Christopher W Frames,Rahul Soangra et al.
Thurmon E Lockhart et al.
Epidemiological studies link increased fall risk to obesity in older adults, but the mechanism through which obesity increases falls and fall risks is unknown. This study investigates if obesity (Body Mass Index: BMI>30 kg/m2) influenced ga...
