The performance of consensus and atomic broadcast algorithms using failure detectors is often affected by a trade-off between the number of communication steps and the number of messages needed to reach a decision. In this paper, we model the performance o ...
Consumer decision support systems (CDSSs) help online users make purchasing decisions in e-commerce Web sites. To more effectively compare the usefulness of the various functionalities and interface features of such systems, we have developed a simulation ...
Trust is the expectation of a person about another person’s behavior. Trust is important for many security related decisions about, e.g., granting or revoking privileges, controlling access to sensitive resources and information, or evaluating intelligence ...
In this exploratory paper we consider a robust approach to decisional problems subject to uncertain data in which we have an additional knowledge on the strategy (algorithm) used to react to an unforeseen event or recover from a disruption. This is a typic ...
[ 1] Retention in upstream storage dams results in modified riverine water and particle discharge patterns. Particularly, suspended solids input and intrusion dynamics in downstream lakes are affected by dam operations. In a case study, size-dependent part ...
Economic development policies such as the Enterprise Zone have been pursued with different designs by state and local governments in many countries. These programs can be defined by a double objective: to promote and control economic growth. This thesis in ...

In a service-oriented e-commerce environment, it is a crucial task to help consumers choose desired products efficiently from a huge amount of dynamically configured product candidates. Decision agents can be designed to provide interactive decision aids f ...
Product end-of-life treatment is unavoidable, no matter how well the product is designed. European regulations becoming stringent regarding the disposal of products, emphasis on end-of-life (EOL) issues at the conceptual design stage gained in importance. ...
Set agreement, where processors decisions constitute a set of outputs, is notoriously harder to analyze than consensus where the decisions are restricted to a single output. This is because the topological questions that underly set agreement are not about ...
