Automatic Persistent Inspection of SkyTran Track System

The monitoring of the SkyTran track condition is imperative. Damaged tracks can cause a fatal crash that can even claim lives. A mechanism for an automatic persistent inspection of SkyTran track system is suggested. The paper suggests employing basic digital camera that can produce JPEG images for this task. If a damage track segment is detected, the traffic in this segment should be halted imm...

Namely, the weighting scheme, the use of stopwords, and the number of learners that contribute to the decision of which documents to ask the virtual assessor to review. We observed that the baseline was extremely strong and none of the runs signi...
