Whether the Troxler effect (TE) has to do with interocular suppression and/or summation was studied with dichoptically matched (binocular or dioptic) and unmatched (monocular) stimulus presentations. Perceptual disappearance was found to occur more slowly under the binocular condition (mean=14.2s) than the monocular condition (mean=8.4s), but much faster than predicted by probability summation ...

The chaotic characteristics and maximum predictable time scale of the observation series of hourly water consumption in Hangzhou were investigated using the advanced algorithm presented here is based on the conventional Wolf's algorithm for the largest Lyapunov exponent. For comparison, the largest Lyapunov exponents of water consumption series with one-hour and 24-hour intervals were calculate...

Implementations of the celebrated Gosper algorithm (1978) for indefinite summation are available on almost any computer algebra platform. We report here about an implementation of an algorithm by Karr, the most general indefinite summation algorithm known. Karr’s algorithm is, in a sense, the summation counterpart of Risch’s algorithm for indefinite integration. This is the first implementation...

Using Rogers’ nonterminating 6φ5 summation and elementary series manipulations, we give a simple proof of Bailey’s very-well-poised 6ψ6 summation. This proof extends M. Jackson’s first proof of Ramanujan’s 1ψ1 summation.

methanol steam reforming plays a pivotal role to produce hydrogen for fuel cell systems in a low temperature range. to accomplish higher methanol conversion and lower co production, the reaction was catalyzed by cuznfe mixed oxides. various ratios of fe and cu/zn were coprecipitated in differential method to optimize the cuznfe structure. the sample containing 45cu50zn5fe (wt. %) revealed its m...

Abstract The timing of short extreme rainstorm, which was usually thought to occur on midsummer afternoons, investigated improve future mitigation options for infrastructure and safety from localised flash flooding. Using a peak-over-threshold approach, the 10- 60-min events filtered high-resolution rainfall series assessing diurnal, seasonal, annual distributions analysed spatial variations pr...
