Storage Capacity of Opportunistic Information Dissemination Systems

Information storage capacity of discrete spin systems

What is the limit of information storage capacity of discrete spin systems? To answer this question, we study classical error-correcting codes which can be physically realized as the energy ground space of gapped local Hamiltonians. For discrete spin systems on a D-dimensional lattice governed by local frustration-free Hamiltonians, the following bound is known to hold; kd 1/D ≤ O(n) where k is...

Information dissemination in social-featured opportunistic networks

Multimedia data dissemination in opportunistic systems

Opportunistic networks (OppNets) are human-centric mobile ad-hoc networks, in which neither the topology nor the participating nodes are known in advance. Routing is dynamically planned following the store-carry-and-forward paradigm, which takes advantage of people mobility. This widens the range of communication and supports indirect end-to-end data delivery. But due to individuals’ mobility, ...

Information Storage Capacity

The storage of information in biological memory relies on changes in neuronal circuits, termed plasticity. Synaptic contributions to plasticity, which are an important component, may be divided into changes in existing synapses, and changes in interneuronal connectivity through formation and elimination of synapses. Interneuronal connectivity changes may be further divided into contributions as...

Library and dissemination of health information

Purpose: The aim of this research is to determine the role of public and academic libraries in disseminating of health information and comparing of the two types of libraries with each other. Method: The research method is applied with descriptive-survey. The sample size was determined by using the Morgan table, 379 people. The questionnaires were distributed using Quotas sampling method. ...
