A WALKING DISTURBANCE INDEX SUGGESTIONS FOR OPTIMIZED PATH SEARCH FOR THE PEOPLE WITH REDUCED MOBILITY
AHP FUZZY LOGIC OPTIMIZED PATH FOR THE PEOPLE WITH REDUCED MOBILITY
2015/11/3
Recently, due to the increased penetration of smart devices and the development of geographic information system (GIS) technology, various route guidance services for pedestrians have been developed. ...
The problem of communication with disturbance constraints is introduced. The rate–disturbance region is established for the single constraint case. The optimal encoding scheme turns out to be the same...
