The design procedure of a second-generation wavelet packet decomposition, based on an evolutionary approach, is introduced for industrial fault detection. The procedure has been validated by means of an experimental case study for an induction motor used as traction machine in an elevator system. Preliminary results on three mechanical faults related to ball-bearing show encouraging performance.

We study the problem of checking whether a two-player reachability game admits more than a winning strategy. We investigate this in case of perfect and imperfect information, and, by means of an automata approach we provide a linear-time procedure and an exponential-time procedure, respectively. In both cases, the results are tight.

We describe a circular (radial) thin-layer chromatographic procedure for separating urinary oligosaccharides. Results were better than those obtained by a single linear development. Bands and specific patterns were finely resolved for various known oligosaccharidoses. The procedure provides a simple means of screening for these disorders.

The TIPS procedure is an endovascular operation guided by biplane fluoroscopy. The goal is to pass a needle from the hepatic vein through the liver into the portal vein. We are developing a software for real-time, 3D guidance of the procedure. This paper discusses means of automatically defining the needle from biplane fluoroscopic views.

Mass spectrometry (MS) is an important technique for chemical profiling which calculates for a sample a high dimensional histogram-like spectrum. A crucial step of MS data processing is the peak picking which selects peaks containing information about molecules with high concentrations which are of interest in an MS investigation. We present a new procedure of the peak picking based on a sparse...

Creation procedure of associative patterns ensemble in terms of formal logic with using neural network (NN) model is formulated. It is shown that the associative patterns set is created by means of unique procedure of NN work which having individual parameters of entrance stimulus transformation. It is ascertained that the quantity of the selected associative patterns possesses is a constant.

thyroglossal duct cysts are the most common congenital anomalies in thyroid development, which in less than 1% of cases are malignant. in most cases the diagnosis is made postoperatively. up to now, a few cases have been reported which had been papillary carcinoma. controversies exist concerning its nature and treatment. we present a 30 years old woman with papillary carcinoma of thyroglossal d...

The One-way Analysis of Variance (ANOVA) is a procedure for testing the hypothesis that K population means are equal, where K > 2. The One-way ANOVA compares the means of the samples or groups in order to make inferences about the population means. The One-way ANOVA is also called a single factor analysis of variance because there is only one independent variable or factor. The independent vari...

The degradation of two amorphous silicon-based photovoltaic (PV) modules, namely, single junction silicon (a-Si) and micromorph tandem (a-Si/ μ $$ \mu -Si), after 11 years exposure in the south Spain is analyzed. Their I-V curves were measured outdoors to study changes electrical parameters course three different periods: during initial days exposure, first year, subsequent 10-year period. tran...

In this paper we describe our approach to building dialog context sensitive language models for improving the recognition performance in spoken dialog systems. These methods were developed and successfully tested in the context of a large-scale commercially deployed system that takes in over ten million calls each month. Dialog sensitive language models are typically built by clustering dialog ...
