Abstract A mathematical model of the magnetic field in working gap a brushless motor is considered case rotor misalignment arising during manufacture, for example, due to defects end shields, or operation bearing wear. uniform (circular ring). The stator gearing taken into account on average using Carter coefficient, inhomogeneous air gap, created by magnets and winding current, assumed be plan...

abstract   background: fractures of the tibia are important for their commonness and controversy in their management. both conservative and surgical techniques have been introduced in an effort to speed time to :::::union::::: while minimizing the occurrence of complications. standard treatment for low-energy tibial shaft fractures includes closed reduction and cast immobilization. the purpose ...

We present a simple motorized rotation mount for half-wave plate that can be used to rapidly change the polarization of light. use device switch high power laser beam between different optical dipole traps in an ultracold atom experiment. The uses stepper motor with hollow shaft, which allows propagate along axis minimizing inertia and mechanical complexity. A machined adapter is wave plate. ch...

The compressive behavior of tapered piles, particularly those with circular cross-sections, has been investigated during the last few decades. However, tensile such piles rarely studied in literature. In this paper, 12 static axial tests, comprising six and were performed on instrumented uniform cross-sections using a geotechnical centrifuge. Three had correspondingly circular, square, X-shaped...

conclusions surgical and post-surgical findings showed that this segment was not related to the patient’s femur. the foreign segment may have belonged to the other victim of this trauma. introduction femoral shaft fracture is one of the typical bone fractures due to high energy trauma and may occur as an open fracture. some foreign materials may enter the fracture site such as sand, cloth parti...

Hollow slabs are of reinforced concrete in which voids allow the to be reduced size. This type slab results raw materials Consumption and increased insulating properties achieve sustainability goals. paper reported an experimental research program focused on study bending behaviour elements hollow normal-strength concrete. Three models one-way were cast, It had dimensions 1020 mm length, 420 wi...
