Because some of the foregoing factors are probabilistic in nature and operate over time, the software reliability models are formulated in terms of random processes. The paper investigates the anticipatory property of software reliability models, focusing on the geometric family of reliability models.

As the complexity of such systems grows, the design of agent societies with a complete pre-defined behaviour is a significant challenge due to the dynamic interactions among agents and between agents and the environment. To overcome existing difficulties, agent systems with emergent behaviour are a fertile area of research and span a large range of applications. The paper presents an analysis of the anticipatory capabilities of multi-agent systems endowed with emergent behaviour, by considering both reactive multi-agent systems and cognitive multi-agent systems. Our approach in analysis is driven by the different levels on which predicted behaviour can be achieved and is illustrated by two scenarios, one for each case of agent system, grounding the view for the cognitive case in our previous related work on self-organizing systems with cognitive agents.

Splaiul Independentei 313, sector 6, 060042, Bucharest, Romania Image retrieval by content represents a part of a multimedia database management system. The components of the image retrieval by content could be seen as anticipatory processes. Each component could anticipate its own evolutionary or functional process or the evolutionary or functional process of other component. This paper presents the anticipatory aspects of the components of an image retrieval by content system.

The model uses negotiation objects and negotiation frames to separate the object of negotiation from the negotiation process. In order to negotiate strategically, the agents use a reinforcement learning algorithm applied on a specific state space representation of the negotiation process.

Many health problems, both acute and chronic, were solved worldwide using Bowtech which, most likely, triggers the body's healing mechanisms. As in many other types of treatment, the relation patient - therapist leads to an individual treatment model, based on both the patient and therapist models of the problem(s) to solve. All these three models include anticipatory aspects, related to the future states of both human systems involved - patient and therapist. The paper presents the authors view of Bowtech as an anticipatory system, including relevant examples from the authors practice.

The paper presents a case study of performance anticipatory analysis, in the context of various functional parameter changes, for the container terminal in Constantza. The results offer valuable information to the management team of the container terminal, in the decision-making process aiming to maximize the terminal efficiency and to offer attractive conditions to their actual or potential clients. The analysis process was conducted using a GPSS simulation model. Anticipated effects of individual and combined functional parameter changes yield by the simulation experiments are extensively discussed.

The paper presents an emotional reasoning model of artificial agents, called Belief-Desire-Emotion( BDE). The model is built upon the influential Belief-Desire-Intention agent architecture and follows the Ortony-Clore-Collin's cognitive appraisal theory of human beings. We describe the different stages of the emotion generation process and emphasize how this process influence theoretical reasoning, such as belief and desire revision, and practical reasoning, such as means-end analysis. Additionally, we propose a set of basic emotions, and we exemplify how they are generated and the way they influence the behavior of our BDE agents.

It points out the relation between the classical and incursive algorithms and shows the effect of incursion on the precision and stability.
