Assessment of product stability
International Journal for Consumer and Product Safety, 1994Abstract In this paper the mechanical stability of consumer products is discussed from both a theoretical and a practical point of view. It is shown that the two methods of stability testing most often used in product safety standards (inclined plane and destabilizing force) can be used for determining a third important parameter, the overturning ...

This chapter describes the implementation of voltage and transient stability assessment tools at California Independent System Operator (CAISO). The architectural setup of the various real-time systems and data flow needed to achieve the implementation of real-time voltage and transient stability assessments that support the requirements laid out in ...

Assessing Biodiversity and Ecological Stability
Science, 2000Jocelyn Kaiser, in her News Focus article “Rift over biodiversity divides ecologists” (25 Aug., p. [1282][1]), repeats the conventional wisdom that Robert May's theoretical work in the 1970s showed that diversity works against stability.

On the Stability of Performance Assessments
Journal of Educational Measurement, 1993This study examined the stability of scores on two types of performance assessments, an observed hands‐on investigation and a notebook surrogate. Twenty‐nine sixth‐grade students in a hands‐on inquiry‐based science curriculum completed three investigations on two occasions separated by 5 months.

Assessing the stability of rolling
Steel in Translation, 2013By plotting histograms and calculating the variation coefficient of the primary drive’s torque in the cells of a continuous rolling mill, the stability of the process may be assessed. The elastic torques and motor torques in cells 5–7 of the 1680 mill in strip rolling were measured simultaneously at OAO Zaporozhstal’, and the results were statistically

Decision Trees for Voltage Stability Assessment
2020 IEEE International Conference on Communications, Control, and Computing Technologies for Smart Grids (SmartGridComm), 2020This paper proposes two different methods to train the DTs for voltage stability assessment, which in turn can aid in deriving preventive actions that can be given as recommendations to system operators or automatic load shedding schemes. In the voltage stability indices method, the DTs are trained on contingency cases that are classified based on ...

A Stability Assessment Methodology
IEEE Power Engineering Review, 1986Weak transmission boundaries are shown to cause steady state and transient stability problems. The weak boundaries are defined by a loss of controllability property of the transient stability model. The loss of synchronism for fault contingencies can occur across these weak boundaries [7] if this boundary is weak compared to the other cutsets that ...

Voltage stability indices for stability assessment: a review
International Journal of Ambient Energy, 2018Right through the past eras, behind numerous shutdowns voltage instability was the cause. Assessment of system voltage consistently ensures safe operation.

Marine Technology and SNAME News, 1980
This paper was originally prepared to provide discussion material for a proposed senior-level course in advanced stability considerations at the University of Michigan. The author has since revised and restructured the paper. The theory and history underlying existing intact stability criteria based on initial GM, righting moment balance and righting ...

Intraoperative Measurements and Tools to Assess Stability
Journal of the American Academy of Orthopaedic Surgeons, 2017Knee stability is the ability for the joint to maintain an appropriate functional position throughout its range of motion. Knee instability can be defined as excessive laxity during activities of daily living. Intraoperative knee laxity can be affected by implant design, alignment of components, and soft-tissue balancing. Soft-tissue balance is a major
