This paper presents the protective effects of shield wire coupled with Metal Oxide Varistor (MOV) arresters in a distribution network located in a severe lightning area. The presented test case is the IEEE 34-node radial distribution test feeder injected with multiple lightning strokes and simulated with the Alternative Transients Program/ Electromagnetic Transients program (ATP/EMTP). The resp...

Although nickel–titanium (NiTi) rotary files are invaluable tools in dentistry, the relationship between their properties and performance has not been elucidated. Herein, of gold heat-treated (ProTaper Gold ProfaTaper Gold), controlled memory (CM)-wire (HyFlex CM V Taper 2H), T-wire (2Shape), R-phase (K3XF) NiTi was evaluated; non-heat-treated ProFile used as control. The bending, buckling, cyc...

AIMS To determine whether the computerised version of the new aniseikonia test (NAT) is a valid, reliable method to measure aniseikonia and establish whether aniseikonia occurs in patients with epiretinal membranes (ERM) with preserved good visual acuity. METHODS With a computerised version of the NAT, horizontal and vertical aniseikonia was measured in 16 individuals (mean 47 (SD 16.46) year...

A numerical method is described that has been used for predicting the dynamic behaviour of a trolley wire overhead contact system when disturbed by the pantograph on the train roof. The vertical motion of the trolley wire is given by the solution of a fourth order partial differential equation and that of the pantograph is given by the solution of ordinary differential equations, these two solu...

the effects of steel wire patenting process parameters on very fine interlamellar spacing in the pearlitic steel wire were investigated and the optimized condition of the process was achieved. in this work, the initial nanopearlitic structure was obtained in a 0.72 wt% carbon steel wire before the wire drawing process. the results were the minimum interlamellar spacing of 35 nm and maximum ulti...

Two real-time, in situmethods tomeasure the breaking force of fine bondingwireswhile on thewire bonder are reported and compared. The firstmethod uses a special test chipwith a piezoresistivemicrosensor integrated next to the bonding pad. A 25 m diameter Au wire piece is attached with a ball bond to the test pad of the microsensor. The wire piece between the ball bond and the lower edge of the ...
