axial flux permanent magnet (afpm) machines are attractive candidates for electric vehicles (evs) applications due to their axial compact structure, high efficiency, high power and torque density. this paper presents general design characteristics of afpm machines. moreover, torque density of the machine which is selected as main objective function, is enhanced by using genetic algorithm (ga) a...

An expanding pin locks the assembly to its supports and bearings prevents any relative movements between surfaces in contact. In this study, diameter changes of bearing inner ring as a function pin’s tightening torque were studied. addition, required rotational moment set complete locked an solution was studied by exposing combination increasing radially outwards directed load from bolt torquin...

Radiofrequency (RF) and intense focused ultrasound (IFUS) are increasingly used to address skin laxity of the face and neck. Both nonablative RF and ultrasound create a heat-induced tissue response that leads to collagen remodeling and other ultrastructural changes. Although these treatments are not meant to replace surgical procedures, patient satisfaction in the majority of studies has been c...

Non-ablative skin tightening is a newer approach to tissue remodeling and skin rejuvenation employing noninvasive procedures. These procedures produce less dramatic effects in comparison to traditional ablative laser resurfacing, but also significantly less healing time and patient discomfort. A variety of non-ablative procedures have been developed to achieve skin tightening through dermal the...

As a simple and highly accurate axial force management method during manufacturing maintenance of bolt-tightened structures, we examined to calculate the from images bolt head. In this method, is calculated using strain on head measured by digital image correlation (DIC) technique relationship between finite element analysis (FEA). We through two comparisons. The first was compare DIC with gaug...

Monopolar radiofrequency (RF) devices are well established treatment modalities for tightening facial skin. A 60-year-old woman presented with a desire to tighten the lax skin and improve the appearance of both upper arms. A combination unipolar and bipolar RF device may provide volume reduction as well as skin tightening in the upper arm.

Paper focuses on biomechanics, specifically on locking cortical bone screws in angularly stable plates used for the treatment of bone fractures in the medical fields of traumatology and orthopaedics. During extraction of titanium-alloy implants, problems are encountered in an effort to loosen some locking bone screws from the locking holes of an angularly stable plate and the subsequent strippi...

Abstract The characterization of mechanical properties materials used in biomedical applications is essential for performance evaluation. In addition to quasi-static tests, dynamic tests extend the range methods and allow predictions failure, as well information on durability. Appropriate specimen grips according test sample geometry are crucial a reliable examination testing therefore valid ex...

This study aims to implement a system-on-chip (SoC) detection system for tool wear monitoring and alarms high-precision machining processes. The proposed deep learning approach is trained by the collected sensors from real performed in three-axial computer numerical control (CNC) machine center combined with different conditions of spindle speed tightening torque. corresponding vibrational soun...
