This paper deals with the description of a procedure to evaluate reliability of a complex diagnosis system. By a four steps procedure it will be shown how to compute a reliability function associated to the whole system starting from the statistical description of the exogenous faults and from the reliability of the diagnosis subsystems devoted to faults detection. A simple example taken from t...

Modelling techniques valid for ordinary hydrological conditions are often inadequate for catastrophic runoff conditions, as the majority of the parameters included in the modelling schemes are not necessarily applicable to flood conditions. To overcome this problem, using a stochastic self-training procedure (SSTP) is proposed. The procedure is based on the real water balance equation and the s...

We propose a procedure to handle the problem of Gaussian regression when the variance is unknown. We mix least-squares estimators from various models according to a procedure inspired by that of Leung and Barron [17]. We show that in some cases the resulting estimator is a simple shrinkage estimator. We then apply this procedure in various statistical settings such as linear regression or adapt...

The discussion of Fractional dimensional Hilbert spaces in the context of Haldane exclusion statistics is extended from the case [10] of g = 1/p for the statistical parameter to the case of rational g = q/p with q, p-coprime positive integers. The corresponding statistical mechanics for a gas of such particles is constructed. This procedure is used to define the statistical mechanics for partic...

In this paper we develop an approximate methodology for estimating the multidimensional quantum density associated with a statistical bundle of de Broglie-Bohm trajectories. The quantum density is constructed as a discrete sum of nonequivalent Gaussian components. We incorporate the ideas of Bayesian statistical analysis and an expectation-maximization procedure to compute an approximate quantu...

The quality of the waste sampling procedure and chemical analysis was evaluated in a research program on characterization of organic waste obtained after disc screening of source-separated organic household waste. The sampling procedures focused on a truckload of waste and involved several steps of subsampling including shredding, mixing, blending, high-speed-blending, drying and milling prior ...

introduction: dark or black coloured gingiva is an esthetic concern especially in subjects with high lip line or gummy smile. gingival depigmentation procedure is a type of perioplastic surgery where the gingival epithelium is excised with various techniques to lighten the colour of the gingiva. the aim of this study was to compare the clinical efficacy of gingival depigmentation procedure with...

Evaluation in visual information retrieval is usually performed by executing test queries and calculating recall and precision based on predefined media collections and ground truth information. This process is complex and time consuming. For the evaluation of feature transformations (transformation of visual media objects to feature vectors) it would be desirable to have simpler methods availa...

In the clinical trial designing stage, trial statisticians need to provide a reference sample size for conducting the trial. In general, this task could be completed by forming the main research question into a statistical procedure and then implementing the published formulae or software, such as n-query and STATA, to make the calculation. When more complex statistical procedures are involved ...
