1. COMPUTER SIMULATIONS IN METAPHYSICS: POSSIBILITIES AND LIMITATIONS
Abstract Computer models and simulations have provided enormous benefits to researchers in the natural and social sciences, as well as many areas of philosophy. However, to date, there has been little attempt to use computer models in the development and evaluation of metaphysical theories. This is a shame, as there are good reasons for believing that metaph

2. MULTI-AGENT BASED MODELING APPLIED TO PORTFOLIO SELECTION IN THE DOOM-LOOP OF SOVEREIGN DEBT CONTEXT*
ABSTRACT This study explores the self-fulfilling dynamic between sovereign debt risk and rational choices of neutral, risk-seeking and risk-averse investors, with implications to the systemic risk emergence. The agent-based model parameterization includes investment strategy (randomly selected assets, stock exchange participation, economic segment, and techn

3. Molecular Modeling, Structural Analysis and Evaluation of 1-Deoxy-D-Xylulose-5-Phosphate Reductoisomerase (DXR) as a Putative Drug Target For Theileria Parva
ABSTRACT The apicomplexan parasite Theileria parva, the causative agent of ECF, is an important pathogen affecting both domestic and wild animals, causing major economic losses in the world. Problems such as high cost of drugs, development of resistance, and absence of effective vaccines prevent effective combating of the pathogen. Thus, it is necessary to e

4. Simulating the behavior of patients who leave a public hospital emergency department without being seen by a physician: a cellular automaton and agent-based framework
The objective of this study was to develop an agent based modeling (ABM) framework to simulate the behavior of patients who leave a public hospital emergency department (ED) without being seen (LWBS). In doing so, the study complements computer modeling and cellular automata (CA) techniques to simulate the behavior of patients in an ED. After verifying and v

5. An agent-based simulation combined with group decision-making technique for improving the performance of an emergency department
This study presents an agent-based simulation modeling in an emergency department. In a traditional approach, a supervisor (or a manager) allocates the resources (receptionist, nurses, doctors, etc.) to different sections based on personal experience or by using decision-support tools. In this study, each staff agent took part in the process of allocating re

6. Racionalidade limitada e a tomada de decisão em sistemas complexos
RESUMO: Este artigo tem o objetivo de apresentar o modelo comportamental de racionalidade limitada proposto por Herbert Simon para analisar o processo de tomada de decisão dos agentes em sistemas complexos, marcados pela não ergodicidade e pelo desenvolvimento de trajetórias em aberto. O artigo apresenta a noção de escolha logicamente consistente em con

7. Planejamento, síntese e avaliação da atividade anti-T. cruzi de derivados furfurilidênicos com estruturas azometínica e oxadiazolínica / Design, synthesis, identification and anti-Trypanosoma cruzi activity evaluation of furfurylidene azomethine and oxadiazole derivatives
The search for alternative therapies for the treatment of Chagas disease presents great importance, since there are only two currently available drugs, nifurtimox and benznidazole. Both have considerable adverse effects and, in Brazil, is used only benznidazole. Nitro-heterocyclic compounds with activity against Trypanosoma cruzi, the causative agent of Chag

8. O setor de internet no Brasil : uma análise da competição no mercado de acesso / The internet sector in Brazil : an analysis of the competition in the access market
The objective of this dissertation is the study of the dynamics of competition in the access market of the Brazilian internet sector, through the application of a History-friendly agent-based simulation methodology, from a complexity theory perspective. The focus of research is the analysis of the processes of sectoral structure organization and change and t

9. Enhancing affective communication in embodied conversational agents through personality-based hidden conversational goals
Embodied Conversational Agents (ECAs) are intelligent software entities with an embodiment used to communicate with users, using natural language. Their purpose is to exhibit the same properties as humans in face-to-face conversation, including the ability to produce and respond to verbal and nonverbal communication. Researchers in the field of ECAs try to c

10. Business competition dynamics : agent-based modeling simulations of firms in search of economic performance
A intenção deste trabalho é explorar dinâmicas de competição por meio de “simulação baseada em agentes”. Apoiando-se em um crescente número de estudos no campo da estratégia e teoria das organizações que utilizam métodos de simulação, desenvolveu-se um modelo computacional para simular situações de competição entre empresas e observar

11. Multi-agent simulation modeling the collective behavior of crowds in panic / Simulação multi-agentes modelando o comportamento coletivo de pânico em multidões
Sociology deals with organized and institucionalized social behavior. However, a distinct type of behavior becomes more relevant in the social studies field. It is an non-institucionalized behavior called Collective Behavior. Since it is not dictated by norms and social rules, its understanding and the building of a computational model present as challenges.

12. Sistemas multiagentes na avaliação pedagógica e na detecção do perfil cognitivo dos alunos: proposta de modelo para uso em ambientes de ensino a distância / Multi-agent systems in learning evaluation and in detection of students learning styles: a proposed model for use in distance education environments.
The computer science is a great allied in the education process. Especially in distance education environment (DEE), the spread of new information and communication technologies have been critical to the broad expansion of this mode of education. These technologies include those in the field of artificial intelligence which have great capacity to adapt to th
