Leader failure is one of the most fundamental problems in distributed systems. This problem can be solved by Leader Election Algorithms (LEAs). These algorithms move the system from an initial state where all the nodes are in the same computation state into a new state where only one node is distinguished computationally (called leader) and all other nodes aware of this leader. This research ai...

this study aimed to examine key factors affecting rural female facilitators’ role in participatory rural development in tehran province. since the researchers intended to have a better insight into the facilitators’ role and employ inquiry as a learning forum for bringing about changes for all participants, they preferred to use a case study based upon an appreciative inquiry method. the study ...

We address the enumeration and the leader election problems over partially anonymous and multi-hop broadcast networks. We consider an asynchronous communication model where each process broadcasts a message and all its neighbours receive this message after arbitrary and unpredictable time. In this paper, we present necessary conditions that must be satisfied by any graph to solve these problems...

Flocking is the ability of a group of robots to follow a leader or head whenever it moves in the plane (two dimensional Cartesian space). In this paper we propose and prove correct an architecture for a self-organizing and stabilizing flocking system. Contrary to the existing work on this topic our flocking architecture do not relies on the existence of a specific leader a priori known to every...

protein aggregation and precipitation is associated with many debilitating diseases including alzheimer's, parkinson's, and light-chain amyloidosis. β-casein, a member of the casein family, has been demonstrated to exhibit chaperone-like activity to protect protein form aggregation. hofmeister salts (lyotropice series) are a class of ions which have an effect on the solubility and also the stab...

We study the parameterized control complexity of fallback voting, a voting system that combines preference-based with approval voting. Electoral control is one of many different ways for an external agent to tamper with the outcome of an election. We show that adding and deleting candidates in fallback voting are W[2]-hard for both the constructive and destructive case, parameterized by the amo...

This paper deals with the automated synthesis of implementations of knowledge-based programs with respect to two synchronous semantics (clock and synchronous perfect recall). An approach to the synthesis problem based on the use of symbolic representations is described. The method has been implemented as an extension to the model checker MCK. Two applications of the implemented synthesis system...

We study the leader election problem in single-hop multichannel wireless networks with single-antenna radio nodes. The objective is to elect leaders for all channels on which one or more nodes in the network can operate. We assume that nodes do not have collision detection capability. In this paper, we propose three algorithms for leader election: one deterministic and two randomized. The deter...

Election is very popular word in the universe. As per the definition, Election is a process to select suitable from a group of candidates. But the process and properties may vary for different sectors. It has different types. Like local election, legislative election, parliamentary election, presidential election, senate election or election in a small group / union. As election is very famous ...
