target coverage is one of the important problems in visual sensor networks. the coverage should be accompanied with an efficient use of energy in order to increase the network lifetime. in this paper, we address the maximum lifetime for visual sensor networks (mlv) problem by maximizing the network lifetime while covering all the targets. for this purpose, we develop a simulated annealing (sa) ...
OBJECTIVE To estimate the prevalence, sociodemographic correlates, comorbidity, and rates of mental health service utilization of fire-setters in the general population. METHOD A face-to-face survey of more than 43,000 adults aged 18 years and older residing in households was conducted during the 2001-2002 period. Diagnoses of mood, anxiety, substance use disorders, and personality disorders ...
BACKGROUND/OBJECTIVES Repetitive mild traumatic brain injury (mTBI, also known as concussion) has been associated with a range of long-term mood and cognitive deficits, including executive dysfunction. Previous research in athletes suggests that cognitive and mood problems are associated with a history of repetitive mTBI. However, to date, no studies have examined the impact of a lifetime accum...
silicon nanowire (sinw) arrays were produced by electroless method on polycrystalline si substrate, in hf/ agno3 solution. although the monocrystalline silicon wafer is commonly utilized as a perfect substrate, polycrystalline silicon as a low cost substrate was used in this work for photovoltaic applications. in order to study the influence of etching time (which affects the sinws length) on d...
Background and Objectives: Using a random sample of women aged 15 to 50 years in Tehran, this study sought to estimate the lifetime prevalence of abortion (intentional and unintentional) and to identify its associated factors. Materials and Methods: The control data of a population-based case-control study conducted in 2014 in Tehran was used in the present study. Data from 544 randomly sel...
In this study, the aging and deterioration mechanisms in the plastic bonded explosives (PBXs) and their components as well as standard methods for their evaluating are presented. Also, the techniques developed for the prediction of chemical lifetime and service life of PBXs will be reviewed and analyzed. These methods cite the lifetime prediction methods based on weight/energy loss by thermal a...
Objectives: This study aimed to evaluate the three and six month clinical and demographic outcome predictors (recurrence rate, the rate of hospitalization, severity of illness and recovery rates) in a group of children and adolescents with type I bipolar disorders. Method: The participants of this longitudinal and prospective study were 80 children and adolescents admitted in Roozbeh Hospital, ...
Objectives This study was done to evaluate the clinical characteristics, function, quality of life, and premorbid adjustment of inpatient children and adolescents with First-Episode Psychosis (FEP) at Roozbeh psychiatric hospital. Methods During a two-year cohort study (2013-2014), all admissions in the child and adolescent psychiatric ward were evaluated. Diagnoses were made using clinical as...
In order to develop a structured and objective diagnostic instrument, authors completed: (1) the translation and back translation of the Korean version of the Kiddie-Schedule for Affective Disorders and Schizophrenia - Present and Lifetime Version (K-SADS-PL) and (2) the examination of its validity and reliability of the K-SADS-PL-Korean version (K-SADS- PL) when used with Korean children. A to...
