We utilize in this work a new class of random fields on some given set of sites, which are invariant under the action of a transit ion probability which synchronously updates the states of all sites. We illustrate, with an issue of image restoration, the usefulness of these models, and their feasibility for practical applications. We begin by a summary of the definition of p-periodic synchronou...

Inspired by potential applications to the smart grid, we develop a heuristic for sub-optimal, but acceptable, control of decentralized systems subject to non-quadratically invariant (non-QI) delay patterns. We do so by exploiting a recently developed solution to the decentralized H2 model matching problem subject to delays, which decomposes the controller into a centralized, but delayed, compon...

One of the current trends in computer science leads to the design of computing organizations based on the activity of a multitude of tiny cheap decentralized computing entities. Whether these chips are integrated into paintings or disseminated in open environments like dust, the fundamental problem lies in their cooperative operation so that global functions are obtained collectively. In this p...

Decentralized Object Location and Routing: A New Networking Paradigm

Recovery of interdependent infrastructure networks in the presence of catastrophic failure is crucial to the economy and welfare of society. Recently, centralized methods have been developed to address optimal resource allocation in postdisaster recovery scenarios of interdependent infrastructure systems that minimize total cost. In real-world systems, however, multiple independent, possibly no...

In this paper, learning-based algorithms for image restoration and blind image restoration are proposed. Such algorithms deviate from the traditional approaches in this area, by utilizing priors that are learned from similar images. Original images and their degraded versions by the known degradation operator (restoration problem) are utilized for designing the VQ codebooks. The codevectors are...

This article proposes two novel approaches to improve the superimposed frequency droop scheme for control of dc microgrids (MGs). Conventional voltage-based strategies suffer from issues such as undesirable voltage regulations, poor power sharing among sources, and negative effects line resistances on equivalent characteristics. To overcome these challenges, a has been introduced. However, this...
