This Paper is an attempt to understand the problems associated with education imparted in distance learning mode by Bhoj Open University, Bhopal, Madhya Pradesh. The paper also deals with the tentative possible solutions to minimise the problems. A study was conducted on 80 students of 2centres of different regions and data was collected related to hub and(More)
We report the results of the electrical resistivity and Seebeck coefficient as well as thermal conductivity measurements on the stoichiometric CaAl(2)Si(2) and non-stoichiometric CaAl(1.75)Si(2.25), CaAl(1.9)Si(2.1), CaAl(2.1)Si(1.9), and CaAl(2.25)Si(1.75) compounds in the temperature range 10-300 K. It has been found that the magnitude of electrical(More)
The objective of the present paper is advancement of knowledge and theoretical understanding of the relations among variables for the study and development using data mining in higher education system and its solution for Madhya Pradesh state. New knowledge takes three main forms: Exploratory research: which structures and identifies new problems,(More)
We report the results of electrical resistivity, magnetic susceptibility and thermoelectric power measurements on the stoichiometric hole-doped La(0.8)Ca(0.2)MnO(3) and electron-doped La(0.8)Ce(0.2)MnO(3) manganites. The resistivity and thermopower data show a metal-insulator phase transition for both samples. Magnetic susceptibility measurement confirms(More)
