ANALYSIS OF USING DIGITAL LEARNING MATERIALS IN ENGINEERING LABORATORY COURSES
Journal Title: Journal of Engineering Studies and Research - Year 2018, Vol 24, Issue 1
Abstract
The paper presents an analysis of the use of digital learning materials in engineering laboratory courses. Interviews have been conducted with lecturers from several engineering faculties of the University of Ruse ‘Angel Kanchev’, such as: the Faculty of Electrical Engineering, Electronics and Automation, the Faculty of Transport, and the Faculty of Mechanical and Manufacturing Engineering. The aim of the interviews is to investigate the capacity and understanding of the lecturers in respect to using digital learning materials in laboratory courses. The obtained results demonstrate that digital learning materials are perceived as a useful tool to achieve better engagement of students in the educational processes. This would require continuous additional efforts by the teaching staff and permanent updating of their specific and digital competences.
SENSITIVITY ANALYSIS OF AVALANCHE PHOTODIODE AND PIN DIODE DETECTORS IN OPTICAL RECEIVERS
This research explained how to establish the optical receiver sensitivity and the link power budget design in terms of quality factor, receiver power and bit error rate (BER) for several values of attenuation at 100km fi...
ARTIFICIAL NEURAL NETWORK IN THE MODELLING OF THE EFFECT OF CHROMIUM DOPANTS ON THE MECHANICAL PROPERTIES OF AL-4%CU ALLOY
Artificial Neural Network (ANN) was used to model the effect of Chromium dopants on the mechanical properties duralumin (Al-4 %Cu). The results showed that the hardness, yield strength, and ultimate tensile strength incr...
INTERACTIONS BETWEEN C6H4(CH2NH3)2[PhCO2]2, Et2NH2[Ph(OH)CO2] AND CuCl2, ErCl3 or SnPh3OH: AN INFRARED STUDY
The interactions of benzoic or salycilic acids salts with di-, trihalides or SnPh3OH have yielded four new complexes and adducts studied by infrared.The suggested structures are discrete or of infinite chain type, the an...
DEARYLATION IN THE INTERACTIONS BETWEEN (Et3NH)HC2O4 OR (Et3NH)2C2O4 AND SnPh3Cl: INFRARED STUDY
Five new oxalato, hydrogenoxalato and hydrogenocarbonato adducts (three) and complexes (two) obtained on allowing (Et3NH)HC2O4 or (Et3NH)2C2O4 to react with SnPh3Cl have been studied by infrared spectroscopy, then discre...
MODELING OF SOLAR RADIATION WITH A NEURAL NETWORK
Modeling of solar radiation with neural network could be used for real-time calculations of the radiation on tilted surfaces with different orientations. In the artificial neural network (ANN), latitude, day of the year,...
