Given a set of robots with arbitrary initial location and no agreement on a global coordinate system, convergence requires that all robots asymptotically approach the exact same, but unknown beforehand, location. Robots are oblivious— they do not recall the past computations — and are allowed to move in a one-dimensional space. Additionally, robots cannot communicate directly, instead they obta...

the conceptualization of resilience as a general or multidimensional construct and recognizing the inhibitors and facilitators of it are the main issues in the resilience literature. therefore, the present study investigated the discriminant variables of educational resilient and emotional resilient groups in person-focused approach, to examine the general or multidimensional construct of resil...

The selection problem, where one wishes to locate the k smallest element in an unsorted array of size n, is one of the basic problems studied in computer science. The main focus of this work is designing algorithms for solving the selection problem in the presence of memory faults. These can happen as the result of cosmic rays, alpha particles, or hardware failures. Specifically, the computatio...

optimal level of regulation and regulatory reform seem to be an undisputed objective . however, in the context of financial regulation there are differences and disagreements over the optimal level of disclosure of information and capital adequacy standards. in this paper, instead of offering a substantive solution , we argue for a competitive process through which the optimal level of disclosu...

Millimeter-wave networks have the potential to supplement fiber in providing high-speed Internet access, as well as backhaul for emerging mobile 3G and 4G services. However, due to the high frequency of operation (70–90 GHz), such networks are highly susceptible to attenuation from rain. In this paper, we present several mechanisms to overcome the disruptive effects of rain storms on network co...

Resilience means different things in different disciplines. From a systems engineering perspective, we define resilience as the ability of a system to adapt affordably and perform effectively across a wide range of operational contexts, where context is defined by mission, environment, threat, and force disposition. A key issue in engineering resilient systems is the lengthy and costly upfront ...

Big cities in developing countries face many obstacles related to the built environment when confronted by socioeconomic inequalities, which is reflected uneven access basic living infrastructure, such as sanitation and housing. In light of new approaches traditional materials building techniques, this article aims investigate use digital fabrication tools production lightweight precast systems...

Structured peer-to-peer overlays provide a natural infrastructure for resilient routing via efficient fault detection and precomputation of backup paths. These overlays can respond to faults in a few hundred milliseconds by rapidly shifting between alternate routes. In this paper, we present two adaptive mechanisms for structured overlays and illustrate their operation in the context of Tapestr...
