Abstract. Purpose. The work’s aim is to study the horizontal supports stiffness impact, which simulate conditions for supporting domes upper tier on von Mises trusses' stability. Methodology. A three-hinged truss' deformed scheme under applying a concentrated vertical load in ridge joint was considered. An analytical method used obtain generalized equation stability criterion determine critical...
Process tolerancing based on the process capability studies is the optimistic and pragmatic approach of determining the manufacturing process tolerances. On adopting the define–measure–analyze–improve–control approach, the process potential capability index (C p) and the process performance capability index (C pk) values of identified process characteristics of connecting rod ...

in this research, a braiding-pultrusion production line is developed by modifying a conventional textile maypole braiding machine and adding it to a pultrusion line for production of braid-pultruded (bp) composite rods. in order to evaluate the mechanical properties of bp rods and study the effect of some braiding parameters, they were produced with different braid roving linear densities and b...
The calculation method of steel pipe support in current specifications is not uniform, and it unsafe to directly apply the stability coefficient vertical bar code, which leads frequent safety accidents fastener supports. Through field statistics initial defects pipe, found that bending values 3 m 6 pipes with largest size are larger L/400. table obtained by taking L/400 as defect, 43.15% smalle...
The inverse problem is posed of stabilizing a spherical pendulum (a mass point at the end weightless solid rod length l ) in given position using high-frequency vibration suspension point. determined by angle between and gravity acceleration vector. For any pendulum, series oblique parameters (amplitude velocity vector vertical) were found that stabilize this position. From obtained solutions, ...
background chronic hepatitis c virus (hcv) is associated with extra hepatic autoimmune disorders, while peg-ifna-2a/rbv combination therapy may exacerbate these conditions. autoantibodies to cytoplasmic structures, called rod and ring particles (rr), have strong associations with these patients and are identified by hep-2 cells. objectives our purpose was to study the correlation of autoantibod...
STUDY DESIGN Three types of anterior thoracolumbar multisegmental fixation were biomechanically compared in construct stiffness and rod-screw strain. OBJECTIVES To investigate the effects of rod diameter and rod number on construct stiffness and rod-screw strain in anterior thoracolumbar multisegmental instrumentation. SUMMARY OF BACKGROUND DATA No studies have been undertaken to investigat...
the coordinate transformation allows the exact calculation of some electrode configurations. in this paper the prolate spherical coordination transformation is used to calculate the field of a hyperboloiderod against plan electrode. the exact field is caculated using two new parameters: 1) electrodes spacing and 2) the radius of curvature of the tip of the rod electrode. the partial discharge i...
