In recent years, 3D printed arm casts can replace traditional to treat bones fractures. cast modelling often uses professional scanning systems capture data of the arm. These are very expensive and may not be available in many hospitals. order over-come this disadvantage, inexpensive methods should developed. This paper introduces a new collection method based on smartphones. The photos an were...

Aim: The purpose of this study was to evaluate the effects different extracoronal attachment lengths and designs on frictional resistance vertical force required create that in fixed partial dentures (FPD). Setting Design: Finite element analysis. Materials Methods: Four manufacturers were considered for FPD's attachments because their varying length options (3 mm, 3.5 4 4.5 5 mm). Catia V5 sof...

Involute spur gears are key machine elements for power transmission in various industrial sectors. During transmission, the teeth subjected to high stresses. Many design modifications used reduce these stresses, such as increasing drive side pressure angle and profile shifting factor. These change contact ratio center distance of gear pair. Changing tooth thickness is another solution stress. B...

UAV aircraft with a fixed wing configuration multi-rotor are capable of vertical take-off and landing (VTOL). In designing the structure aircraft, weight factor strength factors that need to be considered. The use sandwich composite materials on wings is expected able meet requirements namely having light weight, high rigidity strength. this study, comparative analysis balsa wood VTOL VX-2 was ...

The intake port of a CA4DD diesel engine was investigated by computational fluid dynamics (CFD) numerical simulation to enhance the swirl and improve flow characteristics in engine. uniform design method applied study influence guide vanes with different parameters on process at various valve lifts. Nine vane models were established compared base model using CATIA™ 3D CAD software. Numerical si...

This study aims to improve the vehicle vertical dynamics performance in sprung and unsprung state for in-wheel-motor-driven electric vehicles (IWMD EVs) while considering unbalanced magnetic force effects. An integrated vibration elimination system (IVES) is developed, containing a dynamic vibration-absorbing structure between IWM suspension. It also includes an active suspension based on delay...
