Agent-mediated electronic institutions belong to a new and promising field where interactions among agents are regulated by means of a set of explicit norms. Current implementations of such open-agent systems are, however, mostly using constraints on the behaviour of the agents, thereby severely limiting the autonomy of the agents. In this paper we propose an extension to electronic institution...

I will address a challenge to mentalistic theories of norms, such as that developed by Cristiano Castelfranchi and Rosaria Conte, namely, the existence of large normative systems, which successfully direct people’s thoughts and actions without being, in their entirety, mental contents of individual agents. I will argue that the cognitive attitudes and operations involved in compliance with norm...

norms in an institution specification Ins are subsumptions between descriptions stated in Lins, that is, elements of Γins\Γbridge or Ains\Abridge (see Definition 5.4). Concrete norms are, in contrast, subsumtpions between descriptions stated in Lbrute. The connections between the two is provided by the subsumptions of Ins to be found in Γbridge or Abridge. An example follows which clarifies the...

A comparison of different T-norms and S-norms for interval type-2 fuzzy number weights is proposed in this work. The interval type-2 fuzzy number weights are used in a neural network with an interval backpropagation learning enhanced method for weight adjustment. Results of experiments and a comparative research between traditional neural networks and the neural network with interval type-2 fuz...

abstract Let A be Hermitian and let the orthonormal columns of X span an approximate invariant subspace of X. Then the residual R = AX XM (M = X H AX) will be small. The theorems of this paper bound the distance of the spectrum of M from the spectrum of A in terms of appropriate norms of R.

Abstract. We prove a weak-type (1,1) inequality involving conditioned square functions of martingales in non-commutative L-spaces associated with finite von Neumann algebras. As application, we determine the optimal orders for the best constants in the non-commutative Burkholder/Rosenthal inequalities from Ann. Probab. 31 (2003), 948-995. We also discuss BMO-norms of sums of non commuting order...
