Formal nonmonotonic systems try to model the phenomenon that common sense reasoners are able to “jump” in their reasoning from assumptions ∆ to conclusions C without their being any deductive chain from ∆ to C. Such jumps are done by various mechanisms which are strongly dependent on context and knowledge of how the actual world functions. Our aim is to motivate these jump rules as inference rules designed to optimise survival in an environment with scant resources of effort and time. We begin with a general discussion and quickly move to Section 3 where we introduce five resource principles. We show that these principles lead to some well known nonmonotonic systems such as Nute’s defeasible logic. We also give several examples of practical reasoning situations to illustrate our principles. [less ▲]

This paper contributes to a debate on linguistic identity and social participation in France by providing a critical reading of language policy and practice. It challenges the notion that France is a linguistically homogenous nation where a standardised French language is universally practiced and, rather, seeks to reframe linguistic diversity and heterogeneity as fundamental and legitimate constitutive features of French society. In exploring diversity from this critical perspective, the paper looks to the ways in which a number of artists and language activists are deliberately and consciously transgressing normative notions of French to affirm the legitimacy of their alterity and difference. The paper does not make an argument against the legitimacy or social value of standard French, but rather argues in favour of a more critical and inclusive approach to cultural and linguistic difference in France.

Within the framework of this thesis two apparatuses for an absolute measurement of gravity were designed, constructed, and tested for the purpose of detecting long-term variations of gravity, determining the absolute gravity value for metrological applications, and for research in fundamental physics. The work includes a stationary gravimeter, which functions as a highly accurate reference system and a portable gravimeter, which is aimed for field measurements. The principle these gravimeters use to determine the gravity value is based on the relation between the falling distance, the falling time, and the acceleration due to gravity. A Michelson interferometer measures the distance change between a falling object mirror and an inertial reference mirror with a Helium-Neon laser (633 nm). The whole fringe signal is digitized by a high-speed ADC, which is disciplined by a rubidium frequency standard. This fringe recording is novel compared to common gravimeters, which use an analogue zero-crossing determination. [less ▲]

Two experiments investigated the effect of encoding two standard intervals on the performance in a temporal generalization task. Previous research has suggested that when individuals compare current time intervals with a standard encoded within both the auditory and the visual modality, they apparently use both the auditorily and the visually encoded standard for comparison so that each interval was compared with a “mixture” of both standard representations. However, the results of this study showed that memory mixing also happened within a pure visual modality. Moreover, it could be shown that the occurrence of memory mixing depended on instructional ambiguity. If in the training phase both standard durations were erroneously declared to be the same, memory mixing did occur in the testing phase. If, however, both standard durations were described as being different, memory mixing was not observed. [less ▲]

Prior studies of the power spectra of GPS position time series have found pervasive seasonal signals against a power-law background of flicker noise plus white noise. Dong et al. (2002) estimated that less than half the observed GPS seasonal power can be explained by redistributions of geophysical fluid mass loads. Much of the residual variation is probably caused by unidentified GPS technique errors and analysis artifacts. Among possible mechanisms, Penna and Stewart (2003) have shown how unmodeled analysis errors at tidal frequencies (near 12- and 24-hour periods) can be aliased to longer periods very efficiently. Signals near fortnightly, semiannual, and annual periods are expected to be most seriously affected. We have examined spectra for the 167 sites of the International GNSS (Global Navigation Satellite Systems) Service (IGS) network having more than 200 weekly measurements during 1996.0–2006.0. The non-linear residuals of the weekly IGS solutions that were included in ITRF2005, the latest version of the International Terrestrial Reference Frame(ITRF), have been used. To improve the detection of common-mode signals, the normalized spectra of all sites have been stacked, then boxcar smoothed for each local north (N), east (E), and height (H) component. The stacked, smoothed spectra are very similar for all three components. Peaks are evident at harmonics of about 1 cycle per year (cpy) up to at least 6 cpy, but the peaks are not all at strictly 1.0 cpy intervals. Based on the 6th harmonic of the N spectrum, which is among the sharpest and largest, and assuming a linear overtone model, then a common fundamental of 1.040 ± 0.008 cpy can explain all peaks well, together with the expected annual and semiannual signals. A flicker noise power-law continuum describes the background spectrum down to periods of a few months, after which the residuals become whiter. Similar sub-seasonal tones are not apparent in the residuals of available satellite laser ranging (SLR) and very long baseline interferometry (VLBI) sites, which are both an order of magnitude less numerous and dominated by white noise. There is weak evidence for a few isolated peaks near 1 cpy harmonics in the spectra of geophysical loadings, but these are much noisier than for GPS positions. Alternative explanations related to the GPS technique are suggested by the close coincidence of the period of the 1.040 cpy frequency, about 351.2 days, to the ‘‘GPS year’’; i.e., the interval required for the constellation to repeat its inertial orientation with respect to the sun. This could indicate that the harmonics are a type of systematic error related to the satellite orbits. Mechanisms could involve orbit modeling defects or aliasing of site-dependent positioning biases modulated by the varying satellite geometry. [less ▲]
