Travel-dependent businesses like hotels and car rental agencies would be hit hard.
To an extent not fully appreciated by policy makers, the organization says, business travel is dependent on fragile technological networks that have already shown the stresses of a sudden strain.
The rate of travel is dependent on the values of the distribution coefficients, the components interacting more strongly with the stationary phase requiring longer time periods for elution (complete removal from the column).
The distance that traffic noise can travel is dependent on the frequency of the noise, for example, the low frequency rumbling of heavy goods vehicles compared with the high frequency squeaking of brakes.
Locomotor activity of juvenile rats was affected by presentations of acoustic stimuli (see Fig. 2), since the distance travelled was dependent on a) whether acoustic stimuli were presented or not and b) which type of stimulus was presented.
Travel firms less dependent on package holidays are more optimistic.
If the size of the Hardest Hit march was relatively small compared with last autumn's student demonstrations (with police estimates ranging between 3,000 and 8,000), consider the hurdles facing many of the participants – the everyday problems of inaccessible public transport, and the high cost of rail travel for those dependent on disability benefits.
This new model formulation can deal with flow dependent travel times and is a generalization of the previously known strategy (hyperpath) based transit network equilibrium models.
In addition, we suggest an objective function to minimize the total travelled time on the network, which depends on link flow and arc queue length, that recognizes the Wardrop user equilibrium, where travel time is dependent on both flow and queue length on the arc.
The appropriate level of abstraction, and indeed the importance of air travel itself, is dependent on the disease being studied and the question being asked.
