Ellipsoidal outer-bounding under model uncertainty is a natural extension of state estimation for models with unknown-but-bounded errors. The technique described in this paper applies to linear discrete-time dynamic systems. Many difficulties arise because of the non-convexity of feasible sets. Analytical optimal or suboptimal solutions are presented, which are counterparts in this context of u...

This discussion paper is/has been under review for the journal Hydrology and Earth System Sciences (HESS). Please refer to the corresponding final paper in HESS if available. Abstract In this paper, a technique is presented for assessing the predictive uncertainty of rainfall-runoff and hydraulic forecasts that conditions forecasts uncertainty on the forecasted value itself, based on retrospect...

This paper analyses the uncertainty in the estimation of shape from different cues, specifically motion, stereo, and texture. It is shown that there are computational limitations of a statistical nature that previously have not been recognized. Because there is noise in all the input parameters, we cannot avoid bias. The analysis of shape from multiple views rests on a new constraint which rela...

In this paper, filtering algorithms are derived for the least-squares linear and quadratic estimation problems in linear systems with uncertain observations coming from multiple sensors with different uncertainty characteristics. It is assumed that, at each sensor, the state is measured in the presence of additive white noise and that the Bernoulli random variables describing the uncertainty ar...

Purpose Experiments are the backbone of development process data-driven predictive models for scientific applications. The quality experiments directly impacts model performance. Uncertainty inherently affects experiment measurements and is often missing in available data sets due to its estimation cost. For similar reasons, very few compared other sources. Discarding based on uncertainty value...

natural hazards such as earthquakes have threatened the life of human beings during the history.as a consequence, the vibration mitigation of structures has caught great importance. activecontrol of structures is one of the rapidly emerging areas in the concept of structural control. thispaper presents a control method to deal with this subject when the dynamics of the structure ishysteretic an...

slope stability analysis is a geotechnical engineering problem characterized by many sources ofuncertainty. in slope stability computations, some of these sources are encountered, such as geologicaldetails missed in the exploration program, estimation of soil properties that are difficult to quantifyand many other relevant factors. therefore, accurate reproduction of the spatial variability in ...
