Distance Education in the Digital Era and Connectivism Theory
Background: With the arrival of the industrial Century, the educational system changed and different forms of education, including distance Education were created. Firstly, distance education based on traditional learning theories, but because that these theories are not able to respond and solve the challenges facing the education system in the modern century connectivism theory was creat...
متن کاملDigital Distance Relaying
Increasing interest is being shown in the use of microprocessor for protection, switching and data acquisition required in modern high voltage substations. One of the most difficult functions to fulfill is that of transmission line distance protection employing samples of the voltage and current waveform taken from high voltage transducer equipment at the usual relaying point. This paper examin...
متن کاملA Novel Algorithm for Digital Distance Relaying
Distance relays are used to protect EHV and HV Transmission lines. Over the past decades many algorithms have emerged for digital distance relays. These are based on the calculation of the transmission line impedance from the relaying to fault points. In this paper a novel method for digital distance relaying is proposed. In the method the tracking procedure is implemented. The method uses the ...

متن کاملReducing the distance in distance education
Tutor Marked Assignments (TMAs) are the major mechanism by which Open University (OU) students receive feedback on their academic progress. This paper shows how the OU has used ICT to improve both the quality of feedback and speed of response to student work, reduce feelings of isolation and make the university seem less remote. The paper examines the system for online submission and return of ...
