The current mainstream in economic research is intensively supplemented by new modelling paradigms that have been established only recently. Application of agent-based modelling in the realm of economic systems labelled as Agent-based Computational Economics (ACE) represents one rapidly evolving approaches. On the other hand, there is a lack of research focused on timebanks (TBs) as an economic...

background : to prepare safe and adequate blood supply to meet patients’ needs and ensure a sufficient number of regular blood donors, knowledge about factors encouraging people to donate blood regularly is essential. considering its importance, we aimed to identifying the effective factors of the return to blood donation in based on zero-inflated count regression models using bayesian approach...

A comparative workflow, including linear and non-linear QSAR models, was carried out to evaluate the predictive accuracy of models and predict the inhibition activity of a series of aryl-substituted isobenzofuran-1(3H)-ones. The data set consisted of 34 compounds was classified into the training and test sets, randomly. Molecular descriptors were selected using the genetic algorithm (GA) as a f...

The defining characteristic of wireless and mobile networking is user mobility, and related to it is the ability for the network to capture (at least partial) information on where users are located and how users change location over time. Information about location is becoming critical, and therefore valuable, for an increasingly larger number of location-based or location-aware services. One k...

Modeling Macroeconomies as Open-Ended Dynamic Systems of Interacting Agents Blake LeBaron and Leigh Tesfatsion, AER Papers & Proceedings, 98(2), 246-250 “All models are wrong, but some are useful.” G.E.P. Box (1979, p. 202) Macroeconomists seek to understand the structure and performance of economies at a national or regional level and the manner in which government policy makers attempt to inf...

Role-based access control is an important access control method for securing computer systems. A role-based access control policy can be implemented incorrectly due to various reasons, such as programming errors. Defects in the implementation may lead to unauthorized access and security breaches. To reveal access control defects, this paper presents a model-based approach to automated generatio...
