Despite the significance of matched devices in analog circuit design, mismatch modeling for design application has been lacking. This paper addresses misconceptions about MOSFET mismatch for analog design. t mismatch does not follow a simplistic 1 ( area) law, especially for wide/short and narrow/long devices, which are common geometries in analog circuits. Further, t and gain factor are not ap...

In 2005, Railsback et al. proposed a very simple model (Stupid Model) that could be implemented within a couple of hours, and later extended to demonstrate the use of common ABM platform functionality. They provided implementations of the model in several agent based modelling platforms, and compared the platforms for ease of implementation of this simple model, and performance. In this paper, ...

Abstract: We present an experience of applying an extension of Formal Concept Analysis to UML class model restructuring. The Relational Concept Analysis (RCA) mines potentially useful abstractions from UML classes, attributes, operations and associations and therefore outscores competing restructuring techniques which usually focus exclusively on classes. Nevertheless, the complexity and the si...

Knowledge-intensive activities can typically not be modeled sufficiently by classical, static process models and workflows. To enable a process-oriented knowledge management approach under these circumstances, the concept of weakly-structured workflows has been developed. This approach integrates process modeling and workflow enactment and facilitates active information support in dynamically c...

The value of information technology (IT) is often realized when continuously being used after users’ initial acceptance. However, previous research on continuing IT usage is limited for dismissing the importance of mental goals in directing users’ behaviors and for inadequately accommodating the group context of users. This in-progress paper offers a synthesis of several literature to conceptua...

Experimental data from a spatially explicit dynamic commons dilemma experiment is used to empirically ground an agent-based model. Four distinct patterns are identified in the data. Two naïve models, random walk and greedy agents, do not match the patterns. A more comprehensive model is presented that explains how agents make movement and harvest decisions. Using pattern oriented modeling the p...

We present a pulmonary alveolar epithelial cell model and its simulation results aimed to provide mechanistic insight into biological principles that underlie alveolar morphogenesis in vitro. Primary human alveolar type II cells in 3D cultures have been shown to undergo processes of cell migration and aggregation to form hollow cystic structures that resemble human lung alveoli. Although variou...

Modeling crowd behavior is an important challenge for agent-based simulation. My overall goal is to provide a single computational cognitive mechanism that, when executed by individual agents, would give rise to different crowd behaviors, depending on the perceptions and actions available to each individual. I propose a novel model of crowd behavior, based on Social Comparison Theory (SCT), a p...

The adoption of new technology depends on various factors, such as the type of technology, the context or culture in which the technology is introduced, and the individual decisions by people within that culture. This work presents an approach that uses an agent-based model to encompass the detailed behavior of individuals and their immediate network of relationships, as well as an influence-ba...

Fine grained behavioural models of humans in a context, such as associates in an organization or a consumer group may allow us to both better understand existing behaviour as well as what would happen given various situations. We have been working on a behaviour compositional approach to this problem which creates realistic agent behaviour models that when run as a simulation allows us to under...
