Abstract Designing vibrating systems is challenging due to component interaction. One approach reduce the resulting complexity top-down design where requirements on components are formulated such that overall system achieves goal. Previous work showed how derive quantitative and solution-neutral of a system, expressed as permissible ranges impedance. This adapts methodology practical use case p...

in this research, a first order markov chain model was applied to simulate soil salinity in nine standard depths and 10 classes in the cultivated pistachio areas of ardakan city. transition probability matrix, kernel and uniform distribution were used to simulate 500000 soil profiles. results indicate kernel function could reproduce soil salinity values with statistical criteria (i.e. mean, sta...

the photoanthropometric method was used to study the facial features in 136 iranian children with down syndrome, aged 4 to 14 years. nineteen parameters were investigated and compared to an age related control group of 100 normal iranian children. the obtained measurements were related to reference values in the same faces. the normal range was defined by age related index values between the 20...

objectives: down syndrome is the most common chrosomal disorder in which the fine and gross motor skills due to lack of proper sensory experience are disturbed. the role of dexterity in activity of daily living, interaction with environment and independency is quiet crucial in down syndrome. therefore, the aim of this study was to investigate the effects of simultaneous application of superfici...

Objectives: Down syndrome (DS) is the most common multiple congenital anomaly syndrome associated with a developmental disability. Children with Down syndrome have delay in both motor and mental age. This study carried out to explore relationship between mental and motor age of children with DS. Methods: A cross-sectional study was conducted on 60 participants with DS (5 to 7 years old) usin...
