Designing autonomous systems to perform reconnaissance and surveillance missions is especially challenging. Platforms must coordinate, to make on-line decisions about what to sense, what to communicate and how to manoeuvre to achieve their mission goals. A first step in achieving consistent, coordinated decision making is to provide a means for rapid and efficient distribution of information be...

We describe Razor, a planning-based information-gathering agent that assists users by automatically determining which Internet information sites are relevant to their query, accessing those sites in parallel, and integrating the results. Razor uses a disjunctive graphbased plan representation. It then uses a novel and powerful form of local completeness reasoning in order to transform those pla...

Le travail de la traduction orale Bible (OBT) s’effectuant principalement en Afrique, conférence intitulée Oral Translation Global Gathering 2023 s’est tenue du 10 au 12 janvier à Entebbe, Ouganda. Plus 140 participants, issus 43 pays, représentant des organisations telles que Faith Comes by Hearing, SIL, Seed Company, Wycliffe Alliance, United Societies, Word for the World, ETEN et YWAM, pour ...

Measurement of a quantum system – the process by which an observer gathers information about it – provides a link between the quantum and classical worlds. The nature of this process is the central issue for attempts to reconcile quantum and classical descriptions of physical processes. Here, we show that the conventional paradigm of quantummeasurement is directly responsible for a well-known d...

Google is a powerful search engine. However, by combining Google features and creativity in construction query, it will return sensitive information that usually would not be found by casual users. Attacker could use Google to look for vulnerable targets and passively gather information about their targets to assist further attacks. This paper discusses ways to exploit Google to obtain valuable...

The gathering (or multi-agent rendezvous) problem requires a set of mobile agents, arbitrarily positioned at different nodes of the network to group within finite time at the same location, not fixed in advanced. The extensive existing literature on this problem shares the same fundamental assumption that the topological structure does not change during the rendezvous or the gathering; this is ...

We study the problem of coordinating a set of autonomous mobile robots that can freely move in a two-dimensional plane; in particular, we want them to gather at a point not fixed in advance (GATHERING PROBLEM). We introduce a model of weak robots (decentralized, asynchronous, no common knowledge, no identities, no central coordination, no direct communication, oblivious) which can observe the s...

In this paper we proposed a Cellular Automaton based local algorithm to solve the autonomously sensor gathering problem in Mobile Wireless Sensor Networks (MWSN). In this problem initially the connected mobile sensors deployed in the network and goal is gather all sensors into one location. The sensors decide to move only based on their local information. Cellular Automaton (CA) as dynamical sy...

BACKGROUND Wild plant gathering becomes again a popular and fashionable activity in Europe after gathering practices have been increasingly abandoned over the last decades. Recent ethnobotanical research documented a diversity of gathering practices from people of diverse socio-economic and cultural backgrounds who gather in urban and rural areas. Few efforts were though made to study the motiv...
