In this paper, we propose an efficient scheduling algorithm for problems in which tasks with precedence constraints and communication delays have to be scheduled on an heterogeneous distributed system with an one fault hypothesis. Based on an extension of the Critical-Path Method CPM/PERT, our algorithm combines an optimal schedule with some additional tasks duplication, to provide fault-tolera...

Our society’s critical infrastructures (CI) — energy, water, transportation, communication, critical information infrastructure — lacks of resilience, typically losing essential functionality following adverse events. In the future, the number of climatic extremes may intensify or become more frequent, and building resilience becomes the optimal course of action for large complex systems. CI ar...

In this paper, we introduce a new notion called the dual function for studying Boolean functions. First, we discuss general properties of the dual function that are related to resiliency and additive autocorrelation. Second, we look at preferred functions which are Boolean functions with the lowest 3-valued spectrum. We prove that if a balanced preferred function has a dual function which is al...

Positive psychology as a field focuses on identifying and supporting internal strengths and external resources to promote optimal functioning, flourishing, and resilience in individual, organizations, and communities. Research and interventions from the field are helping people be happy, productive, and resilient. From this perspective, each person has a unique set of strengths, which when used...

This study presents an optimal framework for the operation of integrated energy systems using demand response programs. The main goal of integrated energy systems is to optimally supply various demands using different energy carriers such as electricity, heating, and cooling. Considering the power market price, this work investigates the effects of multiple energy storage devices and demand res...

This paper presents results from an experiment on the effects of retail-price recommendations (RPRs) on consumer and retailer behavior. Despite their non-binding nature, RPRs may influence consumers’ willingness to pay by setting a reference point. Loss averse consumers will then be reluctant to pay a price higher than the recommended one. Furthermore, at a given price level consumers will dema...
