Introduction: Mandibular continuity defects after pathologic resections or traumatic events are difficult cases for reconstruction. Defects involving both hard and soft tissue loss are more challenging, because of problems in soft tissue coverage. The role of the submental flap in this regard is presented. Materials and Methods: In a retrospective study from the archived files of Ghaem Hospi...
The purpose of this study was to determine the immediate effect of three types of shoe insoles, on electromyography activity of selected lower extremity muscles during running on treadmill. The electromyography activity of the rectus femoris, vastus lateralis, vastus medialis, biceps femoris, tibialis anterior and gastrocnemius lateralis muscles of 14 male athletes were recorded in non-insole,...
titanium nitride-copper (tin-cu) nanocomposite films were deposited onto stainless steel substrate using hollow cathode discharge ion plating technique. the influence of cu content in the range of 2-7 at.% on the microstructure, morphology and mechanical properties of deposited films were investigated. structural properties of the films were studied by x-ray diffraction pattern. topography of t...
تولید حرکت متعادل ربات دوپا در حرکت از مسیر شیبدار با استفاده از روش های soft computing مورد بحث و بررسی قرار گرفته است. در این تحقیق با در نظر گرفتن یک مدل دو بعدی 7 درجه آزادی در صفحه sagittal معادلات سینماتیکی و دینامیکی ربات استخراج شده است. سپس با استفاده از توانمندی الگوریتم ژنتیک در بهینه سازی و شبکه عصبی در یادگیری و حل بلادرنگ مسایل پیچیده، به برنامه ریزی حرکات پایدار برای ربات پرداخته...
Cherenkov radiation is generated when relativistic charged particles move in a medium with refractive index larger than unity. Although, the refractive index is generally smaller than unity in X-ray region, in the vicinity of atomic absorption edges, the refractive index may exceed unity and Cherenkov radiation can be generated in soft X-ray region with a narrow band width. In this paper, the s...
