For a numerical physical quantity v, because of the measurement imprecision, the measurement result ṽ is, in general, different from the actual value v of this quantity. Depending on what we know about the measurement uncertainty ∆v def = ṽ − v, we can use different techniques for dealing with this imprecision: probabilistic, interval, etc. When we measure the values v(x) of physical fields at ...

In this study we investigated an approach to the calculation of a Standardized Streamflow Index (SSI) that allows accurate spatial and temporal comparison of the hydrological conditions of a stream or set of streams. For this purpose the capability of six three-parameter distributions (lognormal, Pearson type III, log-logistic, General Extreme Value, Generalized Pareto and Weibull) and two diff...

r a 200 .005 dress: Ke , China. ail.ouc.e Summary The Changjiang (Yangtze River) has been effectively gauged since the 1950s and demonstrates the transformation of a river system due to intensified human activities in its drainage basin over the past 50 yr. However, the 50-yr measurements of water and sediment are inadequate to show the long-term trend of sediment flux from the river to the sea...

An non-contact type application on the permanent magnet and linear Hall-effect sensors gauging rotary system is introduced in this paper. For such a contactless system, there will be low wear exhaust. This leads to a longer life span in association, and in particular, high reliability to achieve continuous use. The main component of the angular gauge depends on the Hall voltage under the rotati...

We discuss a gauging procedure that allows us to construct lagrangians dictate the dynamics of an underlying Cartan geometry. In sense be made precise in paper, starting datum is Klein pair corresponding homogeneous space. What amounts construction geometry modelled on geometry, with gauge field defining connection. The lagrangian itself consists all gauge-invariant top-forms constructed from c...
