This thesis proposal aims to provide a new approach to the study of complex adaptive systems in social sciences through a methodological framework for modeling and simulating these systems like artificial societies. Agent based modeling (ABM) is well fitted for the study of social systems as it focuses on how local interactions among agents generate emergent larger and global social structures ...
Organizations that make use of computer information systems (CIS) are prototypical complex adaptive systems (CAS). This paper shows how an approach from Complexity Science, exploratory agent-based modeling (ABM), can be used to study the impact of two different modes of use of computer-mediated communication (CMC) on organizational culture (OC) and performance. The ABM includes stylized represe...
This paper proposes the use of methods for network analysis in order to study the properties of a dynamic graph that model the interaction among agents in an agent-based model. This model is based on Multi Agent System definition and simulates a multicultural crowd in which proxemics theory and distance perception are taking into account. After a discussion about complex network analysis and cr...
In this paper, agent-based models of emergent ancient urban centers are constructed through the use of techniques from computational intelligence, agent-based modeling, complex systems, data-mining, and existing archaeological data from the prehistoric urban center, Monte Albán. The models are used to determine the extent to which the structure of ancient cities relates to the structural model ...
Overview While there is considerable diversity in the domain of complex adaptive systems modeling research Niazi (2013), there are only a handful of books in the market suitable for use in complexity-related courses. Existing books include Boccara’s “Modeling Complex Systems” Boccara (2010) and books with a focus on agent-based modeling including Macal and North’s textbook Macal and North (2007...
Interactions between people are the basis on which the structure of our society arises as a complex system and, at the same time, are the starting point of any physical description of it. In the last few years, much theoretical research has addressed this issue by combining the physics of complex networks with a description of interactions in terms of evolutionary game theory. We here take this...
Information and communication technology (ICT) products exhibit positive network effects.The dynamic process of ICT markets evolution has two intrinsic characteristics: (1) customers are influenced by each others’ purchasing decision; (2) customers are intelligent agents with bounded rationality.Guided by complex systems theory, we construct an agent-based model and simulate on complex networks...
To answer challenge of targeted and controlled drug release in oral delivery various materials were studied by different methods. In the present paper, controlled metal based drug (Pd(II) complex) release manner of β‑Lactoglobulin (β-LG) nanoparticles was investigated using mathematical drug release model in order to design and production of a new oral drug delivery system for gastrointestinal ...
A simple and sensitive extractive spectrophotometric method is described for determination of tropicamide. The method is based on the reaction of tropicamide and bromocresol green. The ion-paired colored complex was extracted with chloroform at pH 3. The extracted complex showed maximum absorbance at 423 nm. The complex was stable up to 2 days and obeyed Beer's law over the concentration r...
رآیند ردوکس زوج nadh/nad+ که در بیش از 330 آنزیم دی هیدروژناز است در سال های اخیر از موضوعات مهم تحقیقاتی بوده که دارای کاربردهای تجزیه ای و زیستی است. در این کار ما از الکترود کربن شیشه ای اصلاح شده با نانوصفحات گرافن و کمپلکس روتنیوم شامل لیگاند 1و 10 -فنانترولین 5و 6- دی اون به عنوان بستری مناسب برای اکسایش الکتروکاتالیتیکی nadh بکار گرفته شده است. رفتار الکتروشیمی الکترود اصلاح شده به وسیله...
