the present study aimed to investigate the generic organization of research article introductions in local iranian and international journals in english for specific purposes, english for general purposes, and discourse analysis. overall, 120 published articles were selected from the established journals representing the above subdisciplines. each subdiscipline was represented by 20 local and 2...

Abstract Abstract Background: Availability and affordability of medicines are crucial to achieving success in prevention programs, particularly in developing countries. Objective: The aim of this study was to determine the availability and affordability of cardiovascular medicines for secondary prevention in Tehran province of Iran. Methods: A cross-sectional survey was conducted in Tehran pro...

background: as a disease of motor nervous system (motor neuron  disease), amyotrophic  lateral  sclerosis (als)  has  a great  impact  on  several  aspects  of  quality  of  life (qol). generic questionnaires of qol do not address all the especial features  of als and  therefore  translation  and  validation of disease specific questionnaires such as amyotrophic lateral sclerosis assessment  qu...

Face expression recognition is useful for designing new interactive devices offering the possibility of new ways for human to interact with computer systems. In this paper we develop a facial expressions analysis and synthesis system. The analysis part of the system is based on the facial features extracted from facial feature points (FFP) in frontal image sequences. Selected facial feature poi...

This paper addresses two fundamental research problems in the domain of context aware autonomic systems: the development of a generic context model that can be used to represent general purpose contexts in a system interpretable way and the autonomic context model management. The proposed context model uses two equivalent and synchronized ways of representing the context: a set based representa...

Most large cities are spanned by more than one transportation system. These different modes of transport have usually been studied separately: it is however important to understand the impact on urban systems of coupling different modes and we report in this paper an empirical analysis of the coupling between the street network and the subway for the two large metropolitan areas of London and N...

Interacting State Machines (ISMs) are used to model reactive systems and to express and verify their properties. They can be seen both as automata exchanging messages simultaneously on multiple buffered ports and as communicating processes with explicit local state. We introduce generic ISMs, extending the ISM formalism with global state. We give a typical instantiation, namely support for dyna...

This paper examines the generality of features extracted from heart rate (HR) and skin conductance (SC) signals as predictors of self-reported player affect expressed as pairwise preferences. Artificial neural networks are trained to accurately map physiological features to expressed affect in two dissimilar and independent game surveys. The performance of the obtained affective models which ar...

The modulational instability (MI) of plane waves in nonlocal Kerr media is studied for a general response function. Several generic properties are proven mathematically, with emphasis on how new gain bands are formed through a bifurcation process when the degree of nonlocality, sigma, passes certain bifurcation values and how the bandwidth and maximum of each individual gain band depends on sig...
