Investigation on RFI effects in bandgap voltage references

In this paper the susceptibility of integrated bandgap voltage references to Radio Frequency Interference (RFI) is investigated by on-chip measurements carried out on Kuijk and Tsividis bandgap circuits. These measurements highlight the offset in the reference voltage induced by continuous wave RFI and the complete failures which may be experienced by bandgap circuits. The role of the susceptibility of the startup circuit and of the operational amplifier which are included in such circuits is also focused.     

Comments on my critics.

Allan R. Buss responds to Bavelas' and Macdonald's criticisms of Buss's article (see record 1976-26634-001) on the evaluation of Canadian psychology departments. Buss says that Bavelas' (see record 2007-04411-001) criticisms are, in the main, important, insightful, and fundamentally correct and that Macdonald's (see record 2007-04410-001) criticisms are, in contrast to Bavelas', highly original, unimportant, and fundamentally incorrect.

Endurance time is joint-specific: A modelling and meta-analysis investigation

Static task intensity–endurance time (ET) relationships (e.g. Rohmert's curve) were first reported decades ago. However, a comprehensive meta-analysis to compare experimentally-observed ETs across bodily regions has not been reported. We performed a systematic literature review of ETs for static contractions, developed joint-specific power and exponential models of the intensity–ET relationships, and compared these models between each joint (ankle, trunk, hand/grip, elbow, knee, and shoulder) and the pooled data (generalised curve). 194 publications were found, representing a total of 369 data points. The power model provided the best fit to the experimental data. Significant intensity-dependent ET differences were predicted between each pair of joints. Overall, the ankle was most fatigue-resistant, followed by the trunk, hand/grip, elbow, knee and finally the shoulder was most fatigable. We conclude ET varies systematically between joints, in some cases with large effect sizes. Thus, a single generalised ET model does not adequately represent fatigue across joints.

Statement of Relevance: Rohmert curves have been used in ergonomic analyses of fatigue, as there are limited tools available to accurately predict force decrements. This study provides updated endurance time–intensity curves using a large meta-analysis of fatigue data. Specific models derived for five distinct joint regions should further increase prediction accuracy.
