Catalytic processes are today practiced on a vast scale to convert basic feedstocks (today largely petroleum, gas, and coal based) into fuels, plastics, agricultural chemicals, pharmaceuticals, foods, paints/coatings, and numerous other materials that underpin our economy and well-being. Catalysts are also used extensively to provide a cleaner environment by treating automotive and industrial (...

Multibiometric systems are being increasingly deployed in many large scale biometric applications (e.g., FBIIAFIS, UIDAI system in India) because they have several advantages such as lower error rates and larger population coverage compared to unibiometric systems. However, multibiometric systems require storage of multiple biometric templates (e.g., fingerprint, iris, and face) for each user, ...

The use of Radio Frequency Identification (RFID) technology extends historically to the 1970’s, when the first commercial products emerged. The introduction of this technology motivated future research that sought to integrate RFID into various applications ranging from inventory control/monitoring to human/animal tracking. However, the practical significance of this technology was not fully re...

Ontologies in current computer science parlance are computer based resources that represent shared conceptualizations for a specific domain. This paper first introduces ontologies in general and subsequently, in particular, shortly outlines the DOGMA ontology leaning approach. The paper also introduces the reader in the field of Knowledge Discovery in Text before, in the main part, work in prog...

| We describe an algorithm for the detection of ellipse shapes in images, using the Randomized Hough Transform. The algorithm is compared to a standard implementation of the Hough Transform, and the Probabilistic Hough Transform. Tests are performed using both noise-free and noisy images, and several real-world images. The algorithm was found to give improvements in accuracy, and a reduction in...

CSVM (CSV with Metadata) is a simple file format for tabular data. The possible application domain is the same as typical spreadsheets files, but CSVM is well suited for long term storage and the inter-conversion of RAW data. CSVM embeds different levels for data, metadata and annotations in human readable format and flat ASCII files. As a proof of concept, Perl and Python toolkits were designe...

Obviously written against a broad background of experience and careful observation, this book relates a vast amount of current knowledge about children to the practical problems with which nurses are concerned. It comprises, essentially, a discussion of the behavior of children and parents; the psychological, physical, physiological, and social growth of children; the interpersonal relationship...

Collagen breakdown, and thus bone resorption, can now be assessed by measuring the urinary excretion of the collagen crosslinks, pyridinoline (Pyd) and deoxypyridinoline (Dpd). In a pilot study we measured Pyd and Dpd in 20 patients with breast cancer, ten with known bone metastases and ten with no recognised metastases in bone or elsewhere after 1 year's subsequent follow up. Eight out of the ...

Similarity measures based on distances are usually more or less sensitive to variations within a data distribution, or the dimensionality of a data space. The effects of the notorious ‘curse of dimensionality’ have been studied in data generated by one single mechanism. In this paper, we study the effects of this phenomenon on different similarity measures in the presence of several data distri...
