for detection of mild to moderate degrees of malnutrition, mid- arm-head circumference ratio of 458 of low income children of isfahan were studied. the percentage bf children with a mid-arm-head circumference ratio of above 0.310, between 0.310 and 0.280, between 0.279 and 0.250, and less than 0.250 were 31.00, 51.75, 15.28 and 1.97 respectively. a significant correlation was found between the ...

height measurement is an important part of nutritional assessment especially in children. however, in such cases as hospitalized or certain kinds of malformations or disabilities, height cannot be measured accurately. we aimed to determine appropriate height predictors in iranian healthy children for further use in disabled and/or hospitalized children. a total of 730 apparently healthy childre...

this study on the design of pid controllers for flexible single-arm robot system optimizationpso method is focused so that the coefficients of the pid controller are reduced. in this study,pid controller and pso algorithm have been described and then by using matlab, pidcontrol was simulated. then by pso algorithm, attempts to reduce the pid coefficients are givenby simulation. finally pid coef...

You know the power of words. We pass through periods dominated by this or that word it may be development, or it may be competition, or education, or purity or efficiency or even sanctity. It is the word of the time. Well just then it was the word Thrift which was out in the streets walking arm in arm with righteousness, the inseparable companion and backer up of all such national catch-words, ...

The outrigger arm system and belt truss with braced core in the center of the structure surrounded by belts truss, is an efficient and reliable system for high-rise buildings against severe lateral forces such as earthquake and wind. The purpose of this research is investigating the outrigger arm system and belt truss with the braced core under lateral loads. Another purpose of this research is...

Almost Perfect Nonlinear(APN) S-boxes are used in block ciphers to prevent differential attacks. The non-evidence of permutation APN S-box on even number of variables and the efficiency of power functions bring the importance of power APN S-boxes to use in block ciphers. We present a special class of 3-to-1 S-box on even number of variables. The power APN S-boxes on even number of variables fal...

This paper aims to develop a writing robot by recognizing the speech signal from the user. The robot arm constructed mainly for the disabled people who can’t perform writing on their own. Here, dynamic time warping (DTW) algorithm is used to recognize the speech signal from the user. The action performed by the robot arm in the environment is done by reducing the redundancy which frequently fac...
