One of the most important techniques in data preprocessing for data mining is feature selection. Real-world data analysis, data mining, classification and modeling problems usually involve a large number of candidate inputs or features. This paper proposes an ant colony optimization (ACO) algorithm for the feature selection problem. The goal is to find the set of features that reveals the best ...

Concrete is the most undisputable and indispensable material being used in infrastructure development throughout the world. The objective of this paper is to utilize marble, granite and Spent Fire Brick waste of different sizes in the manufacturing of concrete bricks, with partial replacement of conventional coarse and fine aggregates with Marble, Granite and Spent Fire Brick waste content up t...

Pulmonary alveolar proteinosis (PAP) is a rarely seen disease of the alveoli, characterized by accumulation of proteinous material, which stains positive with periodic acid Schiff, in the alveoli. Secondary PAP may develop as a result of occupational exposure to materials such as silica and indium. In the paper, together with a review of the relevant literature, we present an uncommon case of a...

I the article several unfinished and semi-finished Roman period artifacts made of Proconnesian marble have been described and discussed. They were discovered in the ancient cities of Odessos and Marcianopolis (in Moesia Inferior) and have been dated to the 2nd-3rd c. AD. Among them are gabled sarcophagi, a fluted capital and two statues: of Heracles and the Thracian Horseman. These finds eviden...

This article describes the use of an LVQ neural network for the clustering and classification of marble slabs according to their texture. The method used for the recognition of textures is based on the Sum and Difference Histograms, a faster version of the Co-occurrence Matrices. The input of the network is a vector of statistical parameters which characterize the pattern shown to the net, and ...

The main scope was the development of support code for a marble tile inspection machine. Marble tiles running on a conveyor belt are captured with a linear CCD camera, and the images are being used for geometrically inspection within 300 msec, which is the available time until the tile reaches the selection mechanism right after the inspection chamber. Supporting algorithm should be fully funct...

This paper builds up a bridge between the formal and cognitive modeling of human reasoning aspects. To this end, we focus on empirical studies on playing a certain game, namely marble drop, that involves reasoning about other minds, and build up a formal system that can model the different strategic reasoning methods employed by the participants in the empirical study. Finally, we show how the ...
