The maximum speed of dynamical evolution
 Physica D
, 1998
"... We discuss the problem of counting the maximum number of distinct states that an isolated physical system can pass through in a given period of time—its maximum speed of dynamical evolution. Previous analyses have given bounds in terms of ∆E, the standard deviation of the energy of the system; here ..."

The Maximum Speed of Dynamical Evolution
, 1996
"... this paper. This question can be asked with various levels of sophistication. Here we will discuss a particularly simple measure of speed: the maximum number of distinct states that the system can pass through, per unit of time. For a computer, this would correspond to the maximum number of operatio ..."

Distributed Counting at Maximum Speed
, 1997
"... this paper, we propose an efficient linearizable counter. The definition of efficiency for distributed data structures in general and for a distributed counter in particular is not as immediate as in the uniprocessor case. The number of messages exchanged among processors, or the time needed from th ..."

is bound to be a hot spot that slows the system down. Decentralization is therefore an important explicit criterion [WW97b]. Whenever a theoretical analysis is difficult and one must resort to experiments, speed (measured in throughput, latency, and the like) is the measure of choice that subsumes all

Achieving Maximum Speed on Parallel Buses
, 2001
"... This application report compares two approaches for synchronous bussystem designs. The focus of the report is the comparison of a system using centralsynchronous system clock (CSSC) with a system operated with a sourcesynchronous system clock (SSSC). The basic characteristics of lines, key factor ..."

This application report compares two approaches for synchronous bussystem designs. The focus of the report is the comparison of a system using centralsynchronous system clock (CSSC) with a system operated with a sourcesynchronous system clock (SSSC). The basic characteristics of lines, key factors that influence the bus line delay, and the impedance of bus lines are described. The theoretical advantages of an SSSC system over a CSSC system are based on a comparison of timing budget calculations. Theoretical results are confirmed by measurements, using the GTLP demonstration backplane. In the SSSC mode, the systemclock frequency is, with a clock frequency of 120 MHz, about
Maximum speed of quantum gate operation

It is shown that the minimum operation time of the), where h is Planck’s constant, E is the average over time of the quantummechanical aver ..."

A Simple, Fast, and Accurate Algorithm to Estimate Large Phylogenies by Maximum Likelihood
, 2003
"... The increase in the number of large data sets and the complexity of current probabilistic sequence evolution models necessitates fast and reliable phylogeny reconstruction methods. We describe a new approach, based on the maximumlikelihood principle, which clearly satisfies these requirements. The ..."

of the topology and branch lengths, only a few iterations are sufficient to reach an optimum. We used extensive and realistic computer simulations to show that the topological accuracy of this new method is at least as high as that of the existing maximumlikelihood programs and much higher than the performance

During the application process of a turbocharger, calculations are performed to estimate the life of the compressor impeller, which takes into account the maximum shaft speed and the number of cycles that cause fatigue damage.
