Reducing the locking time or settling time is one of the major challenges in the design of Delay Locked Loop (DLL) based frequency synthesizer. In this paper a common structure for DLL based frequency synthesizer is considered in which the number of delay cells in the direct path is specified. Then, the designed delay locked loop is optimized using genetic algorithm (GA). GA changes the phase-v...
estimation of delay at signalized intersections for mixed traffic conditions of a developing country
delay is one of the principal measures of performance used to determine the level of service (los) at signalized intersections and several methods have been widely used to estimate vehicular delay. very few studies only have been carried out to estimate delay at signalized intersections under mixed traffic conditions prevailing in developing countries like india. in the present study, various p...
objective the purpose of this study was to determine the prevalence and the most common risk factors of motor developmental delay in infants. materials & methods following ethical approval, a study was carried out on the prevalence and risk factors of infants with motor developmental delay. the first stage was conducted through a cross-sectional study to determine the prevalence of motor develo...
to provide the validated and standardized form of the persian version of the ages and stages questionnaires as an appropriate developmental screening tool for evaluation of iranian children's development.this was a cross-sectional study. translation and back-translation, content validity determination, cultural and lingual modifications, pilot study on 100 parents and inter-rater reliability de...
objective mental retardation (mr) or intellectual disability is one of three chronic and disabling neurological disorders of children and adolescents. its prevalence is estimated 1-3% of the population. mr is defined as significant sub-average intellectual functioning and adaptive behavior that become detectable before the age of 18. mr may come into view before 5 years as delay in at least two...
objectives: there are various developmental screening tools that are different in terms of psychometric characteristics and choosing the best one is challenging for the pediatrician. this research was designed to identify the validity and reliability of parents evaluation of developmental status, a developmental screening questionnaire, in 4-60 months-old children in the city of tehran. methods...
background: delayed reporting resulting in advanced stage disease is a common problem in indian cancer patients. this study analysed the impact of various sociodemographic and psychosocial factors on the delayed reporting to healthcare professional (hcp) in oral and oropharyngeal cancer patients. methods: this cross sectional observational study was conducted using a structured questionnaire. q...
among the issues that present a delay in the interpretation and understanding of the quran is considered. ayatollah javadi amoli great interpreter of those people who interpret the qur'an aspects it considers that in fact it leads to a better understanding of the verses which have been presented and delay. this paper presents analytical method to recognize and interpret ayatollah javadi am...
In this paper, stability for uncertain time variant linear systems with time delay is studied. A new sufficient condition for delay-dependent systems is given in matrix inequality form which depends on the range of delay. Then, we introduce a new direct computational method to solve delay systems. This method consists of reducing the delay problem to a set of algebraic equations by first expand...
Background: The aim of study was to determine the frequency of delay referring and related factors in patients with advanced breast cancer, in Imam Khomeini Hospital in the 2000. Materials and Methods: Successively 200 patients were entered the study if they were consentient. A questionnaire was constructed and information was obtained through interviewing. Results: From the cases, 64 patients ...
