The report presents an augmented reality textbook for future blended education. The efficiency of blended learning is discussed. The characteristics of augmented reality technology are described. An experimental augmented reality textbook for mechanical engineering students’ blended training in the University of Ruse is presented.

Abstract Blended Palm Oil Fuel Ash (POFA) concrete has the potential for application in organic acid environments such as peat land. However, there is a need to improve resistance of blended POFA using silica fume pozzolanic material. There are limited studies admixed with exposure. In this study, compressive strength, porosity, and sorptivity been investigated by exposing samples water. Portla...

Under high ambient pressure (5 MPa) and different injection pressures (90, 120, 150 MPa), a high-speed imaging technique was carried out to comparatively investigate the macroscopic spray characteristics of diesel with three types blended fuel in constant volume chamber. The oxygenated fuels were n-butanol (B), pine oil (P), 2,5-dimethylfuran (DMF). All their blending ratio 20%. Results showed ...

Tire pyrolytic oil (TPO) obtained from thermal pyrolysis of scrap tires is not a diesel equivalent fuel which can be used directly in vehicles due to its high density, viscosity, sulfur content, low flash point and cetane index. It only limited way by mixing with (DF) amounts less than 30 %. In this study, the was carried out at heating rates 5 10?C min-1 range 450?600?C, using mixture hierarch...
