land cover map is important for many urban planning and management activities. in this study, in order to produce land cover map of arak city, digital image of liss-iii scanner acquired on 16 june 2006 were employed. first of all, geometric correction with rmse 0.58 pixel was applied. considering the mountainous condition of the study area, topographic correction was applied to the image. in su...

Gait disorders are common in individuals with Parkinson’s disease (PD) and the concurrent performance of motor and cognitive tasks can have marked effects on gait. The Gait Profile Score (GPS) and the Movement Analysis Profile (MAP) were developed in order to summarize the data of kinematics and facilitate understanding of the results of gait analysis. The aim of the present study was to invest...

Utilization of global positioning system (GPS) to analyze the movements of machinery during the asphalt paving process is a growing practice. However, the accuracy of GPS measurements is affected by a number of factors that lead to noise in the GPS data. Due to these missing accuracy in the GPS data the asphalt paving professionals have problems interpreting and using the data in their operatio...

It is interesting to observe unique challenges and opportunities faced in developing countries to solve a problem that has been extensively studied for years and acceptably resolved in the developed world. Map-matching is one of such areas of research. Existing well established map-matching algorithms are based on data mostly from the developed world where road networks are planned, GPS coverag...

The objective of this research was to develop an unmanned surface vehicle (USV) platform for autonomous navigation in the paddy field. The surface vehicle used in this research was a radio controlled air propeller vessel that had been modified into an unmanned surface vehicle platform. A GPS compass system was attached to the top of the USV platform as the navigation system to provide the posit...
