An ex-situ experiment to assess the metal extractive potential of fourteen agriculture plants (Vigna unguiculata, Gossypium hirsutum, Jatropha curcas, etc.) was conducted on Magnesite mines which had above permissible levels of Cadmium and Lead. There was no much difference in the total chlorophyll a and b, carbohydrate and protein contents in the plants grown in the mining soil and adjacent co...

The one of the most time consuming steps for association rule mining is the computation of the frequency of the occurrences of itemsets in the database. The hash table index approach converts a transaction database to an hash index tree by scanning the transaction database only once. Whenever user requests for any Uniform Resource Locator (URL), the request entry is stored in the Log File of th...

the conventional tunneling procedures for example drilling, charging, blasting, loading and supporting, are highly developed. new tunneling machines have recently come into operation and others are under construction or development. impactors are used in large numbers in the coal mining industry. face-heading machines are successfully used in new tunneling procedures in both soft and medium-har...

We classify polycyclic dimension groups, i.e. dimension groups with the underlying group Z and n ≥ 4. Our method is based on geometry of simple geodesic lines on the Riemann surface of genus g ≥ 2. The main theorem says that every polycyclic dimension group can be indexed by single real parameter α, where α is a positive irrational modulo the action of GL(2,Z). This result is an extension of th...

Flow type suspension and homotopy suspension agree for attractor-repellor homotopy data. The connection maps associated in Conley index theory to an attractor-repellor decomposition with respect to the direct flow and its inverse are SpanierWhitehead duals in the stably parallelizable context and are duals modulo a certain Thom construction in general.

This study examined the longitudinal trends of mobile learning (M-Learning) research using text mining techniques in a more comprehensive manner. One hundred and forty four (144) refereed journal articles were retrieved and analyzed from the Social Science Citation Index database selected from top six major educational technology-based learning journals based on Google Scholar metrics in the pe...

It is a known fact that the Wiener index (i.e. the sum of all distances between pairs of vertices in a graph) of a tree with an odd number of vertices is always even. In this paper, we consider the distribution of the Wiener index and the related tree parameter “internal path length” modulo 2 by means of a generating functions approach as well as by constructing bijections for plane trees.

Because of the inherent computational complexity, mining the complete frequent itemset in dense datasets remains to be a challenging task. Mining Maximal Frequent Itemset (MFI) is an alternative to address the problem. Set-Enumeration Tree (SET) is a common data structure used in several MFI mining algorithms. For this kind of algorithm, the process of mining MFI’s can also be viewed as the pro...
