Temperature compensated digital inertial sensor

A circuit which maintains the inertial element of a gyroscope or accelerometer at a constant position by delivering pulses to a rebalancing motor is discussed. The circuit compensates for temperature changes by using a temperature sensor that varies the threshold of inertial element movement required to generate a rebalance pulse which reacts to changes in viscosity of the flotation fluid. The output of the temperature sensor also varies the output level of the current source to compensate for changes in the strength of the magnets of the rebalancing motor. The sensor also provides a small signal to the rebalance motor to provide a temperature dependent compensation for fixed drift or fixed bias

Discussion of "Bayesian Models and Methods in Public Policy and Government Settings" by S. E. Fienberg

Fienberg convincingly demonstrates that Bayesian models and methods represent a powerful approach to squeezing illumination from data in public policy settings. However, no school of inference is without its weaknesses, and, in the face of the ambiguities, uncertainties, and poorly posed questions of the real world, perhaps we should not expect to find a formally correct inferential strategy which can be universally applied, whatever the nature of the question: we should not expect to be able to identify a "norm" approach. An analogy is made between George Box's "no models are right, but some are useful," and inferential systems [arXiv:1108.2177].Comment: Published in at http://dx.doi.org/10.1214/11-STS331A the Statistical Science (http://www.imstat.org/sts/) by the Institute of Mathematical Statistics (http://www.imstat.org

Temperature compensation of digital inertial sensors

Heaters for thermal stabilization are unnecessary when analog dc voltage provided by gyroscope temperature sensor is used to change outputs to compensate for temperature variations. Sensor is normally installed on all precision gryoscopes

CFD assessments within strongly transient domains

Assessments based on CFD snapshots of stable conditions within strongly transient domains do not address many aspects of performance associated with occupant interventions, control actions or changing climate. Such domains (e.g. double skin façades) are characterised by transient flow patterns due to changing weather patterns, actuation of dampers intermittent opening of façade windows and operation of building environmental systems. Importing boundary conditionsfrom whole building simulation is an improvement but it discounts the impact of the flow predictions on the building domain. A transient approach is suggested which is fully coupled to flow and thermal solvers for the building fabric, environmental control systems and air flow regime. The paper reviews a number of patterns of flow evolution in strongly transient domains in response to changes in ambient conditions, damper actuation, façade openings and intermittent flow from mechanical ventilation systems

Rape myth acceptance, victim blame attribution and Just World Beliefs: a rapid evidence assessment

Background: Rape is underreported, potentially because individuals self-blame and/or are blamed by others. Research predominantly illustrates male-perpetrated stranger-rape of females; thus, there may be a perception that rape myth acceptance (RMA) and victim-blaming are most prevalent in males. The purpose of this rapid evidence assessment was to investigate the availability of high-quality research into the effects of Just World Beliefs, perpetrator/victim gender, and stranger- and acquaintance/marital-rape scenarios on victim-blaming and RMA. Methods: Several electronic databases were searched for empirical papers using terms including: ‘victim blame’, ‘rape myth acceptance’, ‘Just World Beliefs’, ‘type of rape’ and ‘gender’. Gough's (2007) weight of evidence framework was used to assess quality prior to inclusion. Findings: Studies retained after filtering and quality assessment suggested that RMA was predictive of victim-blaming with both male and female ‘victims’. Rape myth acceptance is more prevalent in males even in male ‘victim’ scenarios, and Just World Belief was positively associated with RMA. Greater victim-blaming was attributed in stranger- vs. acquaintance-rape scenarios. Discussion: There are no absolute conclusions regarding the role of gender or situational factors and rape-supportive/victim-blaming attitudes. Further empirical research is required to understand the prevalence of RMA in perceptions of marital rape and, particularly, homosexual marital rape

The Wilson Loop in Yang-Mills Theory in the General Axial Gauge

We test the unified-gauge formalism by computing a Wilson loop in Yang-Mills theory to one-loop order. The unified-gauge formalism is characterized by the abritrary, but fixed, four-vector $N_\mu$, which collectively represents the light-cone gauge $(N^2 = 0)$, the temporal gauge $(N^2 > 0)$, the pure axial gauge $(N^2 < 0)$ and the planar gauge $(N^2 < 0)$. A novel feature of the calculation is the use of distinct sets of vectors, $\{ n_{\mu}, n_{\mu}^{\ast} \}$ and $\{N_{\mu}, N_{\mu}^{\ast}\}$, for the path and for the gauge-fixing constraint, respectively. The answer for the Wilson loop is independent of $N_{\mu}$, and agrees numerically with the result obtained in the Feymman gauge.Comment: 12 pages, 2 figure
