Landslide risk analysis using artificial neural network model focussing on different training sites

This paper presents landslide hazard and risk analysis using remote sensing data, GIS tools and artificial neural network model. Landslide locations were identified in the study area from interpretation of aerial photographs and from field surveys. Topographical and geological data and satellite images were collected, processed, and constructed into a spatial database using GIS and image processing. These factors were...

Application of discriminant analysis to predict the class of degree for graduating students in a university system

In this Paper, discriminant analysis was used to predict the class of degree obtainable in a University system. The conditions for predictive discriminant analysis were obtained, and the analysis yielded a linear discriminant function which successfully classified or predicted 87.5 percent of the graduating students’ class of degrees. The function had a hit ratio of 88.2 percent when generalized, as a valid tool...

Effects of household wastes on surface and underground waters

The impact of indiscriminate dumping of waste, particularly household wastes within certain locality in Ondo State, in the western part of Nigeria on the quality of surface water and underground water (that is, wells with rings and without rings) were investigated. The water was analyzed for some physico-chemical parameters and some heavy metals using the standard methods. The results show that wells without rings are...

Study of the electrochemical redox characteristics of some triazolopyrimidines

An electrochemical study related to the redox characteristics of Ethyl-3-acetyl-6-methyl-1,4-diphenyl-4,3a-dihydro-1,3,4-triazolino[3,4-a] pyrimidine-5-carboxylate ester and its derivatives (1a-f) and (2a-e) in nonaqueous solvents such as 1,2-dichloroethane (DCE), dichloromethane (DCM), acetonitrile (AN), dimethylsulphoxide(DMSO) and tetrahydrofurane (THF) using 0.1 mol dm-3 tetrabutylammonium perchlorate (TBAP) as a...

The possible role of dynamic pressure from the interplanetary magnetic field on global warming

Quantitative analyses suggest that the increase in global warming by about 1°C over the last century is related to the increase in geomagnetic activity. Maintained small increases in dynamic pressure in the order of a nanoPascal from the solar wind due to the expansion of the solar magnetic corona may be sufficient to produce the energy that has resulted in the increase of surface temperatures on the Earth and Mars....
