The migration method of a mobile agent affects the entire performance of the distributed system. Most of the existing migration methods have the slow-witted structures due to the fixed order migration that cause the subsequent accumulation of the task results. They can induce various problems such as the failure of host, network obstacles, service absence, and increased traffic resulting in the...

The algorithm may be programmed without multiplication or division instructions and is eficient with respect to speed of execution and memory utilization. This paper describes an algorithm for computer control of a type of digital plotter that is now in common use with digital computers .' The plotter under consideration is capable of executing, in response to an appropriate pulse, any one of t...

While growth has increased in Tanzania during the past five or six years, it is still too low to have a visible impact on poverty. Indeed, recent evidence suggests that the amount of both income and non-income poverty are roughly the same as they were a decade ago. Since debt relief provided under HIPC will free government resources, the initiative will potentially help reduce poverty through l...

Legged vehicles offer several advantages over wheeled vehicles, particularly over broken terrain, but are presently too slow to be advantageous for many tasks. Trotting, the precursor to galloping for many quadrupeds, employs high-speed actuation to coordinate the intermittent ground contacts for each leg. Compliant elements and high-power actuators combine to perform a complex interchange of p...

Overdispersion is a common feature of models of biological data, but researchers often fail to model the excess variation driving the overdispersion, resulting in biased parameter estimates and standard errors. Quantifying and modeling overdispersion when it is present is therefore critical for robust biological inference. One means to account for overdispersion is to add an observation-level r...

We analyze the distribution of PageRank on a directed configuration model and show that as the size of the graph grows to infinity it can be closely approximated by the PageRank of the root node of an appropriately constructed tree. This tree approximation is in turn related to the solution of a linear stochastic fixed point equation that has been thoroughly studied in the recent literature.

The history of science is often regarded today as the progressive accumulation of techniques and the refinement of quantitative methods in the study of Nature. Such a point of view considers the present conception of science to be the only valid one; it therefore judges the sciences of other civilizations in the light of modern science and evaluates them primarily with respect to their "develop...

In a wireless LAN, even if the coverage of the access point (AP) and the mobile terminals are the same, the hidden terminal problem can not be avoided. If the AP and all the mobile terminals have the same coverage with a radius R there will always be terminals in the coverage area of the AP which are hidden to one another. This paper introduces this phenomenon, that we refer to as the natural h...
