Enhanced data mining analysis in higher educational system using rough set theory

  One of the biggest challenges that higher education faces today is predicting the behavior of students. Institutions would like to know, something about the performances of the students group wise. Behrouz–Minaei-Bidgoli (2004) investigated a web based educational system using data mining techniques. He proposed a problem to investigate the performances of the students when the large data base of...

Comparison of electron-plasmon scattering effect on low-field electron mobility in ZnO and SiC

  Iterative technique is used to solve Boltzmann transport equation for calculating temperature and doping dependencies of electron mobility in ZnO and SiC materials. The two-mode nature of the polar optic phonons is considered jointly with deformation potential acoustic, piezoelectric, ionized impurity and electron-plasmon scattering. Band non-parabolicity, admixture of p functions, arbitrary...

Cluster analysis of improved cassava varieties cultivated at Onne, Nigeria by the international institute of tropical agriculture

  Secondary data on proximate composition of “fufu” flour taken from forty three cassava mosaic disease (CMD) resistant varieties were used for this work. Agglomerative hierarchical cluster analysis was performed on the squared Euclidean distance matrix. The distance coefficients generated between the forty three CMD resistant varieties ranged from 0.000 to 89.120. Six (6) distinct groups were...
