a novel approach to determine optimal sampling locations under parameter uncertainty in a water distribution system (wds) for the purpose of its hydraulic model calibration is presented. the problem is formulated as a multi-objective optimisation problem under calibration parameter uncertainty. the objectives are to maximise the calibrated model accuracy and to minimise the number of sampling d...

expanded graphite nanosheets (eg-nanosheets) were used for adsorption of malachite green (mg) from aqueous solution. the influences of dye concentrations, absorbent dosage, ph values and the temperatures on the adsorption were investigated as well. the dye adsorption experiments were carried out by utilizing batch procedure. eg-nanosheets were initially characterized by scanning electron micros...

soil conservation service (scs) adjusted the kostiakovs infiltration model by adding a constant coefficient, for improvement of estimation. the improved model has three constant parameters, which are difficult to calculate. so scs has taken the third constant parameter as equal to 0.65-0.7 cm to simplify the estimation. this parameter varies in different soil and often outranges the scs estimat...

We present a new type of probabilistic model which we call DISsimilarity COefficient Networks (DISCO Nets). DISCO Nets allow us to efficiently sample from a posterior distribution parametrised by a neural network. During training, DISCO Nets are learned by minimising the dissimilarity coefficient between the true distribution and the estimated distribution. This allows us to tailor the training...

Customer Journey Maps (CJMs) summarize the behavior of customers by displaying the most common sequences of steps they take when engaging with a company or product. In many practical applications, the challenge lies in automatically discovering these prototypical sequences from raw event logs for thousands of customers. We propose a novel, probabilistic approach based on a mixture of Markov mod...

Building on a previous important work of Cachin, Crépeau, and Marcil [15], we present a provably secure and more efficient protocol for ( 2 1 ) -Oblivious Transfer with a storage-bounded receiver. A public random string of n bits long is employed, and the protocol is secure against any receiver who can store γn bits, γ < 1. Our work improves the work of CCM [15] in two ways. First, the CCM prot...

Often, at the time when a performance model is built, some of its input parameters are not known exactly. This can be for a variety of reasons, such as the system itself not having been completed, a benchmarking process not yet having been carried out, or that precise estimates for the parameters are very difficult to obtain. In these situations, interval values can be used to express the uncer...

In this paper, we address the problem of tolerating the adverse effects of input faults on the operation of a class of asynchronous sequential machines. Occurring to either the external input or the control input generated by the controller, input faults can cause unauthorized changes of the input value. In the framework of corrective control, we present the necessary and sufficient condition f...
