Energy and sampling constrained asynchronous communication [PDF]

open access: yes2013 IEEE International Symposium on Information Theory, 2013
The minimum energy, and, more generally, the minimum cost, to transmit one bit of information has been recently derived for bursty communication when information is available infrequently at random times at the transmitter. This result assumes that the receiver is always in the listening mode and samples all channel outputs until it makes a decision ...

RoboCast: Asynchronous Communication in Robot Networks [PDF]

open access: yes, 2010
This paper introduces the \emph{RoboCast} communication abstraction. The RoboCast allows a swarm of non oblivious, anonymous robots that are only endowed with visibility sensors and do not share a common coordinate system, to asynchronously exchange information.

From SOS to Asynchronously Communicating Actors [PDF]

open access: yes, 2020
Structural Operational Semantics (SOS) provides a general format to describe a model as a transition system with very powerful synchronization mechanisms. Actor systems are distributed, asynchronously communicating units of computation with encapsulated state, with much weaker means of synchronizing between actors.

Passive testing with asynchronous communications and timestamps [PDF]

open access: yesDistributed Computing, 2017
We develop a formal passive testing framework for software systems where parties communicate asynchronously. Monitors, placed in between the entities, check that a certain property holds over the observations of the interaction between users and the system under test (SUT).

Design and Implementation of a Novel Compatible Encoding Scheme in the Time Domain for Image Sensor Communication

open access: yesSensors, 2016
This paper presents a modulation scheme in the time domain based on On-Off-Keying and proposes various compatible supports for different types of image sensors. The content of this article is a sub-proposal to the IEEE 802.15.7r1 Task Group (TG7r1) aimed

Exploring Individual and Collaborative Dimensions of Knowledge Building in an Online Learning Community of Practice

open access: yesInformatics in Education, 2008
An exploratory study of students' engagement in online learning and knowledge building is presented in this paper. Learning in an online community, composed of students (pre-service teachers) and experts (experienced in-service schoolteachers and ...

The Strongly Asynchronous Massive Access Channel

open access: yesEntropy, 2022
This paper considers the Strongly Asynchronous, Slotted, Discrete Memoryless, Massive Access Channel (SAS-DM-MAC) in which the number of users, the number of messages, and the asynchronous window length grow exponentially with the coding blocklength with

Aide à l'apprentissage du discours oral dans un contexte de communication asynchrone

open access: yesALSIC: Apprentissage des Langues et Systèmes d'Information et de Communication, 2007
We have developed our VoiceForum software solution to solve a basic problem regarding how to help learners in L2 spoken interaction activities. In a task-based approach, which is facilitated by the present trend towards groupware solutions, we discuss ...

Reliance, liance et alliance : opérationnalité des concepts dans l'analyse du climat socio-relationnel de groupes restreints d'apprentissage en ligne

open access: yesALSIC: Apprentissage des Langues et Systèmes d'Information et de Communication, 2020
The aim of the research we are presenting here is to measure the link between the "socio-relational climate" of a small group in a collaborative work environment and the quality of the collective work they provide.

Efficiency of Asynchronous Systems That Communicate Asynchronously [PDF]

open access: yes, 2000
A parallel composition is introduced that combines nets (regarded as system components) by merging so-called interface places; the novel feature is a flexible typing of these places, which formulates assumptions a component makes about its environment.
