every year, many accidents leading to physical injuries in kindergartens, indicates that a very large percentage of them are related to the safety concerns and lack of hygiene in these places. families, due to their busy life style and working hours and also children needs of preschool education, are searching to find most suitable kindergartens for their children. selecting a kindergarten with...

one of the most important challenges in nonlinear, multi-input multi-output (mimo) and time variant systems (e.g., robot manipulator) is designing a controller with acceptable performance. this paper focused on design a new artificial non linear controller with on line tunable gain applied in the robot manipulator. the sliding mode fuzzy controller (smfc) was designed as 7 rules mamdani’s infer...

as it has proven the increase of mechanical strain could resulted to increase of bnp (protein brain natriuretic peptide) in blood stream of implanted patient pacemakers. we measured the bnp concentration in blood due to different mode and lead implantation location of pacemaker in the time period of three month. the aim of study was the investigation of change trend of bnp level after pacemaker...

در این مقاله، به‌منظور رفع برخی محدودیت‌های شناسایی ساختمان تصاویر چندطیفی، از دادة SAR به‌منزلة مکمل استفاده می‌شود. روش پیشنهادی، برای استفادة هم‌زمان اطلاعات مفید رادار و استراتژی مبتنی‌بر تلفیق تصاویر، با هدف ساختمان، مطرح همچنین، ازآن‌جاکه انتخاب ویژگی نقش بسزایی طبقه‌بندی عوارض دارد، اغلب روش‌های مرسوم رایج زمینه، مانند الگوریتم ژنتیک، نیازمند داده‌های آموزشی‌اند؛ اما دردسترس‌نبودن همیشگی...

caesarean section is considered as a major surgery which is accompanied by several complications. the present study aimed to determine the effect of behavioral intention model-based educational intervention on reducing the caesarean section among pregnant women. the present interventional study was conducted on 100 primiparous women in the third trimester of pregnancy who were covered by the he...

abstract the utility of carbon paste electrode for the determination of flavoxate hcl modified with flavoxate-tetraphenylborate (flx-tpb) and flavoxate-phosphotungestic acid (flx-pta) ion-pairs in batch mode is demonstrated. the electrodes revealed a nernstian response over a wide concentration ranges 1.39×10-5-1x10-2 mol l-1 and1×10-5-1x10-2 mol l-1 using flx-tpb and flx-pta, respectively. the...

in recent years, the application of composite materials in aircraft and space vehicle structural components has become increasingly popular. preventing failure of composite structural systems has been an important issue in engineering design. due to the lack of through-the-thickness reinforcement, structures made from laminated composite materials and adhesively bonded joints are highly suscept...

in this paper, a nonlinear model of the underactuated six degrees of freedom (6 dof) quadrotor helicopter was derived based on the newton-euler formalism. a new nonlinear robust control strategy was proposed to solve the stabilizing and path following problems in presence of external disturbances and parametric uncertainties. the proposed control structure consist of a sliding mode control base...
