The ACORN multi-agent system
ACORN (Agent-based Community Oriented Routing Network) is a distributed multi-agent architecture for the search, distribution and management of information in networks. ACORN utilizes the concept of ‘information as agent’ together with an application of Stanley Milgram’s Small World Problem (the idea of Six Degrees of Separation) in order to route individual items of information around networks...
متن کاملACORN: a review.
The ACORN system was originally developed as a means of ab initio solution of protein structures when atomic resolution data were available. The first step is to obtain a starting set of phases, which must be at least slightly better than random. These may be calculated from a fragment of the structure, which can be anything from a single metal atom to a complete molecular-replacement model. A ...
متن کاملAcorn poisoning in cattle.
Ten cows in a suckler herd totalling 60 sickened after grazing parkland which was heavily covered with acorns. Two died. The main clinical signs were dullness, anorexia and constipation. The main pathological findings were severe nephrosis and some intestinal ulceration. After removal to an acorn-free pasture, the remaining eight animals made a full recovery.
متن کاملAcorn Production Patterns
Acorns—the fruits of oaks—are a key resource for wildlife in temperate forests throughout the Northern Hemisphere. Acorns are also economically important for extensive livestock rearing, and as a staple food have supported indigenous human populations. Consequently, differences in how individual trees and populations of oaks invest in acorn production, both in terms of the size of the acorn cro...
متن کاملSome results on ACORN
In this paper we obtain a weakness in the design specification of ACORN, which is a competitor of CAESAR competition. We show that there exists a probabilistic linear relation between message bits and ciphertext bits, which holds with probability greater than 12 . This is the first paper which finds a probabilistic linear relation between message and corresponding ciphertext bits of ACRON, and ...
