Comparison of 3D structural characteristics of high and low resolution X-ray microtomographic images of paper
The detailed 3D structure of paper was revealed applying both high and low resolution X-ray microtomography. The qualityof the two techniques with respect to resolution and volume size was compared by measuring various structural andtransport properties of the digital volumes.
Some factors affecting the grades of technology students
In this study factors that affect the grades of Norwegian technology students have been investigated. The total data set contained 355.706 individual exams from 63 different engineering master programs during the 2010 to 2014 period. Regression analysis showed that the single factor having the largest impact on students’ grades at university was their average grade from high school. Students who had on average one unit better grade from high school got on average 1.4 to 1.7 units better grades in the first year at university and even on their master thesis they got 0.76 units better grades. Strong correlations in the awarded grades for single students were also observed between the differen…
