By contrast, Republican candidate Paul Ryan seemed pedestrian and uncertain, falling back on rehearsed lines of attack.
PIT STOPS Lowe's officials seemed uncertain whether to reopen the pedestrian walkway that collapsed a week ago Saturday, injuring 107 people, three critically.
The study of the probabilistic response of pedestrian-excited structures as well as their reliability analysis need to take into account the influence of a large number of uncertain parameters ascribed to structural characteristics, single pedestrian walking features and pedestrian traffic phenomena.
Tijuana, a sprawling, bustling city, is long accustomed to the daily sight of a gate on the US side swinging open and deportees shuffling across a pedestrian walkway to an uncertain future in Mexico.
On Monday, the city announced a possible remedy for the uncertain: a new, $6 million network of pedestrian maps, oriented in the direction that the viewer is facing — so that someone looking east from Lower Manhattan, for instance, might find the Brooklyn Bridge at the top of the display.
So they are shifting into dollars now. Given the vast size of the foreign-exchange market, however, it is unlikely that criminal money, even Russian criminal money, is big enough to move exchange rates.A more plausible, if more pedestrian, explanation is that, in an uncertain global economic climate, the dollar has resumed its traditional role as a safe-haven currency.
If the characterization of pedestrians' equivalent dynamic parameters is assumed as uncertain, as revealed from a current literature review, then the paper provides a range of possible variations of the coupled system damping ratio and natural frequency as a function of pedestrians' parameters.
Amy Albano said she was uncertain how the city would differentiate "hiker" from other pedestrians.
However, the role of the other two components (i.e., exposure and risk of crash) remains uncertain, partially because it is difficult to determine the amount of exposure in pedestrians accurately (Clifton and Livi 2005; Keall 1995).
