purpose : to determine add power (ap) and amplitude of accommodation (aa) in a sample of iranian population and its relationship with refractive errors methods : this cross-sectional study enrolled people of 35-70 years old by simple random sampling. exclusion criteria were myopia or hyperopia over 6 diopter (d) and astigmatism more than 0.75 d. those with a history of eye disorders and taking ...

Today every circuit has to face the power consumption issue for both portable device aiming at large battery life and high end circuits avoiding cooling packages and reliability issues that are too complex. It is generally accepted that during logic synthesis power tracks well with area. This means that a larger design will generally consume more power. The multiplier is an important kernel of ...

We investigate the large deviation behavior of the overlap probability density in the Sherrington–Kirkpatrick model using the coupled replica scheme, and compare with the results of a large scale numerical simulation. In the spin glass phase we show that generically, for any model with continuous RSB, 1/N log PN (q) ≈ −A ((|q| − qEA), and compute the first correction to the expansion of A in po...

With the appearance of high performance mobile devices, low cost and low power consumption have become important issues in high performance processors. To meet the needs, low cost and low power floating-point fused multiply-add unit is proposed in this paper. According to the area and power consumption analysis, the multiplication part in fused multiplyadd operation accounted for most power con...

In this paper power transient is investigated as function of add/drop wavelength and surviving channel wavelength. We have reported that power excursions varies with different wavelength allocations of the add/drop channels. Transient response is reduced by 73.39% in case when add/drop channels are taken in L band instead of C band. Also power transient response is calculated as a function of w...

We demonstrate a 1×4 coarse wavelength division-multiplexing (CWDM) planar concave grating multiplexer/demultiplexer and its application in re-configurable optical add/drop multiplexer (ROADM) system in silicon-on-insulator substrate. The wavelengths of the demonstrated concave grating multiplexer align well with the ITU-T standard. We demonstrate a prototype of ROADM comprising two such concav...
