Previous studies on inferring the origin of routing changes in the Internet are limited to failure events that generate a large number of routing changes. In this paper, we present a novel approach to origin inference of small failure events. Our scheme focuses on routing changes imposed on preferred paths of prefixes and not on transient paths triggered by path exploration. We first infer the ...

an interactive heuristic approach can offer a practical solution to the problem of linear integer programming (lip) by combining an optimization technique with the decision maker’s (dm) judgment and technical supervision. this is made possible using the concept of bicriterion linear programming (blp) problem in an integer environment. this model proposes two bicriterion linear programs for iden...

This paper proposes the visualization cube as a reference model for spatiotemporal trend information. The interactive visualization system for earthquake trend information was proposed at MuST in NTCIR-6 workshop, which defines earthquake trend information as spatiotemporal information and designs the interaction between different views so that temporal and spatial trend information can be effe...

The Model-View-Controller (MVC) software architecture pattern separates these three program components, and is well-suited for interactive applications where flexible human-computer interfaces are required. Separating data presentation from the underlying process enables multiple views of the same model, customised views, synchronisation between views, and views that can be dynamically loaded, ...

introduction: in the recent years, evaluation of websites has become one of the main organizational instruments for the relationship between provision of services for customers and beneficiaries. despite the high costs for design and implementation of websites, less attention has been paid to evaluation of these websites’ function. this might be due to the lack of appropriate instruments and fr...
