For each of the possible orientations; (i) front (relative angle equal to 0 between current heading and the obstacle), (ii) left (relative angle equal to 45 between current heading and the obstacle on the left), and (iii) right (relative angle equal to 45 between current heading and the obstacle on the right); a table is populated indicating the obstacle's direction and distance.
The opportunity analysis focuses on the improvement of working procedures and working environment and threats indicate the obstacles in job and problems which affect productivity.
See Figure 1, where the shaded rectangle indicates the obstacle defined on one-dimensional (1D) interval ([x_{0},x_{5}]): varphi (x)=left { textstylebegin{array}{l@{quad}l} 0 &mbox{if }x_{0}le x< p, 1 &mbox{if }ple xle x_{5}, end{array}displaystyle right.
Among these, half preferred an obstacle warning consisting of a short sentence indicating the location of the obstacle relative to the user (e.g., "obstacle in front") while the rest wanted the distance of the obstacle to be reported in addition to this warning (e.g., "Obstacle in front at 1 m/4 steps").
It also indicates the political obstacles to bureaucratic restructuring.
The findings indicate the main obstacles for BIM-implementation is related to the lack of normative pressure while the main driving forces were primarily driven by the subjective positive or negative evaluation of BIM by individuals, instead of external pressure from clients and partners or with respect to the internal capacity and knowledge to use BIM.
The study's practical relevance lies in its explorative nature: decision makers are provided with ample evidence indicating the potential advantages and obstacles vocational education teachers face in their attempt to work more efficiently.
As Samir Amin indicated: The real obstacle to the United States hegemony came from the Afro-Asian national liberation movement.
The commonly used medicine called palibe kantu literally means 'there is nothing' indicating that the obstacle to deliver has been removed.
A non-null value is then associated to these cells (i.e. higher values represent cells nearest to the obstacles) according to the following functions: Val ( ObsF, c ) = max { 0, r ob - dist ( c obs, c ) }. Figure 1c represents obstacle field in which lightest values indicate the approaching to the obstacles (in red).
