objective: the aim of the present study was to investigate the epidemiology of psychiatric disorders in ‎children and adolescents in five provinces of iran: tehran, shiraz, isfahan, tabriz and mashhad.‎ method: in the present study, we selected 9,636 children and adolescents aged 6-18 years through ‎multistage cluster random sampling method from tehran, shiraz, isfahan, tabriz and mashhad. ‎we ...

In this paper, borrowing the intuition in Rao et al. (2004), we introduce a cumulative version of the inaccuracy measure (CIM). Also we obtain interesting and applicable properties of CIM for different cases based on the residual, past and interval lifetime random variables. Relying on various applications of stochastic classes in reliability and information theory fields, we stu...

Abstract Wireless sensor networks (WSNs) are used in many different fields. One of the most recent and rapidly expanding applications is Internet Things (IoT), which enables connectivity numerous objects or devices over Internet. However, WSNs have a bigger concern about battery power than mobile ad hoc networks, shortens network's lifetime. As result, extensive research has been done on loweri...

Several previous studies have been performed which evaluate the power consumption of the Itsy pocket computer version 2, developed at Compaq Computer Corporation’s Western Research Laboratory (WRL). Attempts have been made by others to use the data from these studies to characterize the behavior of the Lithium-ion battery used for the Itsy. Although our previous studies correctly characterize t...

This paper addresses two versions of a lifetime maximization problem for target coverage with wireless directional sensor networks. The sensors used in these networks have a maximum sensing range and a limited sensing angle. In the first problem version, predefined sensing directions are assumed to be given, whereas sensing directions can be freely devised in the second problem version. In that...

BACKGROUND Mood Spectrum Self Report (MOODS-SR) is an instrument that assesses mood spectrum symptomatology including subthreshold manifestations and temperamental features. There are different versions of the MOODS-SR for different time frames of symptom assessment: lifetime (MOODS-LT), last-month and last-week (MOODS-LW) versions. OBJECTIVE To evaluate the psychometric properties of the MOO...

Comparison of the theory of Rabi oscillations with experiment [M. Wilczewski and M. Czachor, Phys. Rev. A 79, 033836 (2009)] suggests that cavity lifetime parameters obtained in measurements with many photons may be much smaller than those applicable to almost vacuum states of light. In this context, we show that the conclusion remains unchanged even if one takes a more realistic description of...
