The reconstructed slice quality of flat-detector computed tomography (CT) is often disturbed by concentric-ring artifacts. Since concentric rings in CT slices appear as straight stripes when transformed into polar coordinates, a variation-based model proposed to suppress the stripes. method motivated two observations about coordinates: (1) ring artifacts attenuate gradually along radial direction, leading sparse distribution and (2) greatly distort image gradient across stripes, while...

Abstract A methane detection system based on tunable diode laser absorption spectroscopy (TDLAS) using LabVIEW platform was demonstrated. To suppress the noise interference in system, a wavelet denoising method studied and experiments with different parameters were carried out. With threshold of Hard, basis Coif5 rule Heursure, high frequency noises sensor can be effectively decreased harmonic amplitude increased. Experiments showed that, 1 σ minimum limit (MDL) 23.68 ppbv (part per billion...

An all-optical network (AON) is a in which data does not undergo optical-to-electrical and electrical-to-optical conversion within the network.

Accurate peeling off and transferring of microchips play a critical role in LED die sorting technology. Generally, efficiency more than 36 KUPH, an alignment deviation less 1 mil ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$25.4~\mu \text{m}$ </tex-math></inline-formula> ) is required. High precision position control cooperation multifactors should be implemented precisely. Among all the factors, film...

Semiconductor light-emitting die (LED) has now become one of the most popular lighting devices. Before dies are put into process package, they need be inspected and sorted strictly, so following waste will saved. Cost inspection sort is relatively high, it urgently needed to improve efficiency reduce time.

All dies are required to keep consistent angles in LED chip sorting. Usually, rectification orient real-time vision is used for this but it may decrease production efficiency greatly, because one correction need several adjustments. Considering that all be sorted adhesive wafer tape, each rotated, locations of other change. It a problem following positioning and To solve problem, an on-line angle method basing on translation compensation put forward. In way, deviations transformed as...

The initial excitation of interface crack large-size ultra-thin chips is one the most complicated technical challenges. To address this issue, reversible fracture characteristics a silicon-based chip (chip size: 1.025 mm × 0.4 0.15 mm) adhesive layer was examined by scanning electron microscope (SEM) tests, and cohesive zone model (CZM) unit were obtained through peel testing. fitting curve elastic bilinear in high agreement with experimental data, correlation coefficient 0.98. maximum...

All dies are required to keep consistent angles in LED chip sorting. It is a problem because all chips adhesive wafer tape, each rotated, and locations of other change. Usually, visual rectification used for this. While, correction needs several adjustments, it may decrease production efficiency greatly. To solve this problem, an on-line angle method put forward. Techniques including fast fitting rotating center with machine vision, reverse seeking offset translation distance correction,...

Chip declination correction is a difficult problem in LED chip sorting process. Usually use real-time vision to correct declination. In this way, once may need several adjustments.

This provides optimized template support library, decreases developing time script, implements defined function reuse, does aiming at different size. The experiment shows that it has higher efficiency than DDE framework.

The light-emitting diode (LED) is the world's most efficient light source being mass produced today. As LED industry becomes prosperous, short time consumption for single chip measurement particularly concerned by semiconductor manufacturers. Generally, in each test process, SMD transferred from conveyor line head vibrated with frequency about 5MHZ, and its position set to center of nozzle 40ms cycle. Because vibration adjacent extrusion, some chips may drop or get damage during transfer....

Storage system usually can reach its performance zenith under certain degree of workload in particular application environment. When working other conditions, I/O performs poor because lacking adaptation. This paper describes Heter-RAID (heterogenous RAID) which adjust itself to dynamic get averagely high performance.
