a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
The aim of this paper is to discuss the "Framework for M&S with Agents" (FMSA) proposed by Zeigler et al. (2000, 2008) in regard to the diverse epistemological aims of agent simulations in social sciences. We first show that there surely are great similitudes, hence that the aim to emulate a universal "automated modeler agent" opens new ways of interactions between these two domains of M&S with...
abstract: research purpose: the purpose of this research is to identify academic databases assessment factors and criteria at law and political science majors. the necessity of this research is to distinguish academic databases assessment factors and criteria and to identify the most important ones and rank them in order to select an appropriate database according to students’ and faculty memb...
We present a new agent-based model for the simulation of tax compliance and tax evasion behaviour (SIMULFIS). The main novelties of the model are the introduction of a ‘behavioural filter approach’ to model tax decisions, the combination of a set of different mechanisms to produce tax compliance (namely rational choice, normative commitments, and social influence), and the use of the concept of...
As an emerging approach to explore the dynamics of voter preference, agent-based modeling (ABM) highlights new opportunities for intellectual exchange across disciplines, such as mathematics, political science, communication studies, and computer science. By aiming to contribute to cross-disciplinary communication for a better application of this approach, this paper summarizes what scholars ha...
This paper employs meta-analysis to determine the influence of computer-based scaffolding characteristics and study and test score quality on cognitive outcomes in science, technology, engineering, and mathematics education at the secondary, college, graduate, and adult levels. Results indicate that (a) computer-based scaffolding positively influences learning (g = 0.53), (b) studies with zero ...
The evaluation problem in the empirical literature on the impact of pharmaceutical reference pricing
The objective of this paper is to describe empirical studies evaluating the impact of reference pricing interventions in pharmaceutical markets, and to assess the quality of their evaluation method. A total of ten studies were included in the review. The nature of the intervention, the nature of the data available, the nature of the question to be answered, and the requirements of the evaluatio...
Honing and Ladinig (2008) make the assertion that while the internal validity of web-based studies may be reduced, this is offset by an increase in external validity possible when experimenters can sample a wider range of participants and experimental settings. In this paper, the issue of internal validity is more closely examined, and it is agued that there is no necessary reason why internal ...
