The presence of delay-inducing defects is causing increasing concern in the semiconductor industry today. To test for such delay-inducing defects, scan-based transition fault testing techniques are being implemented. There exist organized techniques to generate test patterns for the transition fault model and the two popular methods being used are Broad-side delay test (Launch-from-capture) and...

We demonstrate wavelength switching in a novel multicavity distributed Bragg reflector semiconductor laser diode. This new device, which uses an integrated saturable absorber and singlemode fiber Bragg gratings, digitally switches wavelength as a function of drive current between all possible binary combinations.

Composition, change and complexity have attracted ev- eryone’s attention towards Self-Adaptive systems. These systems, inspired by the human body, are capable of adapting to changes in the inner and outer environment. The main objective of this study is to achieve a more con- venient availability for e-banking services in the payment switch, using self-healing systems and focusing on the failur...

Wavelength routed optical switching promises low power and latency networking for data centres, but requires a wideband wavelength tuneable source (WTS) capable of sub-nanosecond at every node. We propose hybrid WTS that uses time-interleaved lasers, each gated by semiconductor amplifier, where the performance device is optimised using artificial intelligence. Through simulation experiment we d...

nanoparticles classified in 4 overall groups containing: metallic nanoparticles, ceramic nanoparticles, polymeric nanoparticles and semiconductor nanoparticles. these nanoparticles are used in some biomedical applications such as carrying medicine and photographing agents. with attention to different criteria which are both qualitative and quantitative, selecting the most suitable nanoparticles...

Experiments have been performed with a 100-kJ pulse-forming network (PFN) to characterize the transient behavior of semiconductor diodes serving as capacitor-protecting devices. In addition to the experiments, computer techniques are used to illustrate and predict the dynamic behavior ofPFN diodes. From analyses of the data collected, it was determined that in a PFN under specific loading condi...
