This paper presents an automatic diagnosis system for detecting breast cancer based on association rules (AR) and neural network (NN). In this study, AR is used for reducing the dimension of breast cancer database and NN is used for intelligent classification. The proposed AR + NN system performance is compared with NN model. The dimension of input feature space is reduced from nine to four by ...

In this letter, we established a traveling wave solution by using cosine function algorithm for Gardnerequation and (2+1)-dimensional breaking soliton system. The cosine method is used to obtain theexact solution.

When visual features in the periphery are close together they become difficult to recognize: something is present but it is unclear what. This is called "crowding". Here we investigated sensitivity to features in highly familiar shapes (letters) by applying spatial distortions. In Experiment 1, observers detected which of four peripherally presented (8 deg of retinal eccentricity) target letter...

The orthographies of several languages, such as Yoruba, Arabic, Tshivenda, Ciluba, French, German, and Dutch, use diacritics. These diacritics pose an additional challenge to a character recognition system. Using diacritically-marked uppercase Yoruba letters as a case-study, this paper presents one strategy for addressing this problem. In particular, we present a system for the automatic classi...

This study focuses on the effective pronunciation modelling of words from different languages encountered during the development of a Sepedi automatic speech recognition (ASR) system. While the speech corpus used for training the ASR system consists mostly of Sepedi utterances, many words from English (and other South African languages) are embedded within the Sepedi sentences. In order to mode...

This letter presents a point cloud based robotic system for arc welding. Using hand gesture controls, the scans partial views of workpiece and reconstructs them into complete 3D model by linear iterative closest algorithm. Then, bilateral filter is extended to denoise preserve important geometrical information. To extract welding seam from model, novel intensity-based algorithm proposed that de...

Automatic presentations, also called FA-presentations, were introduced to extend finite model theory to infinite structures whilst retaining the solubility of interesting decision problems. A particular focus of research has been the classification of those structures of some species that admit automatic presentations. Whilst some successes have been obtained, this appears to be a difficult pro...
