PNA Predictability at Various Time Scales

Evaluation of ABR traffic management under various system time scales

In this paper, the eeects of various time scales on the management of ABR (Available Bit Rate) traac using feedback based control is studied. Since delay tolerable, the ABR applications can be allocated the remaining resources after CBR (Constant Bit Rate) and VBR (Variable Bit Rate) applications have been accommodated. To avoid excessive losses the transmission rate of the ABR applications sho...

Modeling fast and slow earthquakes at various scales

Earthquake sources represent dynamic rupture within rocky materials at depth and often can be modeled as propagating shear slip controlled by friction laws. These laws provide boundary conditions on fault planes embedded in elastic media. Recent developments in observation networks, laboratory experiments, and methods of data analysis have expanded our knowledge of the physics of earthquakes. N...

Efficiently Measuring Bandwidth at All Time Scales

The need to identify correlated traffic bursts at various, and especially fine-grain, time scales has become pressing in modern data centers. The combination of Gigabit link speeds and small switch buffers have led to “microbursts”, which cause packet drops and large increases in latency. Our paper describes the design and implementation of an efficient and flexible end-host bandwidth measureme...

Brownian motion at short time scales

Time scales for fission at finite temperature

The concept of the ”transient effect” is examined in respect of a ”mean first passage time”. It is demonstrated that the time the fissioning system stays inside the barrier is much larger than suggested by the transient time, and that no enhancement of emission of neutrons over that given by Kramers’ rate formula ought to be considered.
