Production cars are designed to understeer and rarely do they oversteer. If a car could automatically compensate for an understeer/oversteer problem, the driver would enjoy nearly neutral steering under varying operating conditions. Four-wheel steering is a serious effort on the part of automotive design engineers to provide near-neutral steering. Also in situations like low speed cornering, ve...

Axonal elongation involves the coordinated assembly and activation of molecular pathways in response to environmental signals. Neurons sense the environment at growth cones to decide on further growth, arborization or consolidation. The work by Ana Mingorance-Le Meur and Timothy P. O’Connor highlights the important role of neurite shaft dynamics in the consolidation process. The establishment o...

Electric vehicles (EVs) have gained the attention of many authorities, automakers and researchers due to their considerable energy saving and emission reduction. One of the main issues that must be considered in design of a road vehicle is the calculation of aerodynamic forces. This issue also must be scrutinized in the design of EVs. Installation of rear spoiler is one of the solutions propose...

The automated installation of hi-lok nuts by the robot is an effective way to replace tedious manual labor. For this purpose, appropriate end-effector needs be designed carry out feeding, alignment and fastening tasks. According process nuts, a motor driven tool with two parts: front nut runner rear driving shaft. task modeled based on force balances in screwing action, which present can rotate...

In front wheels driven vehicles, fuel economy can be obtained by summing torques applied to rear wheels. On the other hand, unequal torques applied to rear wheels provides enhanced safety. In this paper, a model with seven degrees of freedom is considered for the vehicle body. Thereafter, power-train subsystems are modeled. Considering an electrical machine on each rear wheel, a fuzzy controlle...

In this study, the entropy theory was used as evaluation standard of energy dissipation, and effect backflow clearance (the gap between motor rotor shell) on characteristics a full tubular pump investigated by 3D unsteady flow simulation. The calculated results validated through testing shows that produces additional head loss rotation requires more shaft power. losses lead to significant decli...

Single blade centrifugal pump is suitable for transporting sewage water with large obstacles in diameter, which required to achieve high performance. The inlet angle a parameter that affects the performance of single pump. However, selection frequently based on experiences and demonstrates certain arbitrariness. Therefore, six impellers different angles are designed using ANSYS Bladegen NX soft...

background:   although intramedullary nailing (imn) is an established and accepted operative treatment for femoral shaft fracture in patients younger than 60, there is a lack of data on the results of this treatment on those over 60. the purpose of this study was to determine if the outcome of imn for femoral shaft fracture in elderly patients is also acceptable. particular challenges in this g...

A typical passive magnetic bearing has been modeled and analyzed for its performance characteristics. The magnetic bearing studied in this work comprised of a Shaft, inner magnets sleeved over the shaft, and outer magnetic rings. A detailed analysis has been perform on the force exerted by a permanent magnet on the shaft nurture to restore the shaft to its equilibrium position when an eccentric...
