Upwinded finite difference schemes for dense snow avalanche modeling Avalanche dynamics models are used by engineers and land-use planners to predict the reach and destructive force of snow avalanches. These models compute t... G Sartoris,P Bartelt - 《International Journal for Numerical Methods in...
In summary, Homework Equations state that: -F=ma, where Fr=the torque created by the tires that will move the car and Iα=the angular acceleration of the car. -If we ignore the friction force, we get that τ-Fr=Iα and τ-mar=Ia/r. -To solve for a, we can ignore the ...

where the change in momentum is equal to the product of force and time interval (Δp=FΔt). It is commonly used in cases where the average force involved acts during a very short window of time, such as when a bat hits a baseball or when a car suddenly collides on a concrete barrie...
The essential prevalent characteristics to empirically test the model are: the oscillation frequency of the railway car in the model for low velocities, the critical velocity, supercritical bifurcations (Hopf bifurcation), chaos and the types of instability (reverse period doubling). Impact oscillators....
In addition, the present study accounts for the impact of hybrid boundaries, including crossed and parallel boundaries, by introducing a finite number of mirror bubbles for the former and an infinite number of mirror bubbles for the latter. Spark bubble experiments and numerical simulation are ...

For the distance between the site of jaywalking and the bus stop, the probability of jaywalking basically follows a normal distribution. The average distance gradually increases, with the increase of the car arrival rate. Additionally, location of the crosswalk has a great impact on the jaywalking...
