load modeling is widely used in power system studies. two types of modeling, namely, static and dynamic, are employed. the current industrial practice is the static modeling. static modelss are algebraic equations of active and reactive power changes in terms of voltage and frequency deviations. in this paper, a component based on static modeling is employed in which the aggregate model is deri...

The spread of rumors, which are known as unverified statements of uncertain origin, may threaten the society and it's controlling, is important for national security councils of countries. If it would be possible to identify factors affecting spreading a rumor (such as agents’ desires, trust network, etc.) then, this could be used to slow down or stop its spreading. Therefore, a computational m...

We live in a very complex world where we face complex phenomena such as social norms and new technologies. To deal with such phenomena, social scientists often use reductionism approach where they reduce them to some lower-lever variables and model the relationships among them through a scheme of equations. This approach that is called equation based modeling (EBM) has some basic weaknesses in ...

in knowledge-based economy, knowledge has a public good and non-rivalry nature. firms build their own knowledge stock not only by means of internal r&d and collaboration with partners, but also by means of previously spilled over knowledge of other firms and public research laboratories (such as universities). firms based on their absorptive capacity, and level of intra-industry and extra-i...

Although the UML and RUP have artifacts to represent components, their emphasis is on deployment and at best, implementation. They do not have full life-cycle support for analysis, architectural and detailed design needed to create componentware. In this tutorial we explore simple extensions to the RUP that have been applied to multiple project engagements and provide workproduct(artifact) and ...

This paper is the first step of an exploration of the possibilities offered by the application of UML to agent-based software. Starting from UML definitions of use cases and actors we discuss their correspondence to agents and external entities of the environment. An example is also presented that starts form a classical well–known case of study.

We use regulatory focus theory to derive specific predictions regarding the differential relationships between regulatory focus and commitment. We estimated a structural equation model using a sample of 520 private and public sector employees and found in line with our hypotheses that (a) promotion focus related more strongly to affective commitment than prevention focus, (b) prevention focus r...

In this paper we will discuss why in some circumstances people express their intentions indirectly: the use of Indirect Speech Acts (ISA). Based in Parikh’s game of part information and Franke’s IBR model, we develop a game-theoretic model of ISA, which is divided into two categories, namely non-conventional ISA and conventional ISA. We assume that non-conventional ISA involves two types of com...

Non-linear, stochastic, thermodynamic, agent based or network modelling are powerful tools brought from other fields into economics. Applied in almost every sub-field of economics, these tools had however substantial success only in the analysis of financial markets. We suggest that the reason for this is less the insufficiency of these technical tools but rather the incapacity of mainstream ec...

We propose using community-centered analyses and agent-based models of scientific gatherings such as conferences, symposia and workshops as a way to understand how scientific practices evolve and transition between local, community, and systems levels in science. We suggest using robotics as a case study of global, cross-cultural, interdisciplinary scientific practice. What is needed is a set o...
