This paper presents a macroeconomic agent based model with endogenous innovation-driven growth and knowledge accumulation which aims to analyze the underlying causes of recent increase in market concentration, by focusing on interplay technical change power, resulting consequences terms higher inequality lower growth. The source concentration lies fact that heterogeneous firms do not have equal...

In this paper, we propose a technique which automatically estimates speakers’ agedness only with acoustic, not linguistic, information of their utterances. This method is realized by integrating GMM(Gaussian Mixture Model)-based speaker recognition techniques with modules for calculating prosody-based agedness scores. We firstly divided speakers of two databases, JNAS and S(senior)-JNAS, into t...

this paper is an attempt to explore the prepositions used to encode the agent in persian passive constructions. according to givón (1983) the main function of the passive constructions is to defocus the agent. as the general trend in persian is to omit this defocused agent, we will stylistically divide the passive constructions into two main sub branches, namely unmarked and marked passives acc...

agent oriented software engineering (aose) is an emerging field in computer science  and  proposes some systematic ideas for multi agent systems analysis, implementation and maintenance. despite the various methodologies introduced in the agent-oriented software engineering, the main challenges are defects in different aspects of methodologies. according to the defects resulted from weaknesses ...

The main aim of this research is to determine optimal leaching conditions; Eh, pH and complexing agent concentrations, for recovery of Copper from hydroxide sludges such as those produced by electroplating shops, metal finishers, treatment of acid mine drainage, and industrial wastewater in general. This has been preceded by a theoretical approach and numerical and computer calculation. Pot...

INTRODUCTION Adjunctive complex fractionated atrial electrograms (CFAE) ablation or ganglionated plexi (GP) ablation have been proposed as new strategies to increase the elimination of AF, but the difference between CFAE/GP ablation and pulmonary vein isolation (PVI), as well as the combined effect of CFAE/GP plus PVI ablation were unclear. This meta-analysis was designed to determine whether a...
