The accuracy of measuring the crossing moment of a given signal to a specific reference voltage plays a crucial role in determining the bandwidth of the signal that could be converted by a level-crossing ADC. This timing accuracy is mainly determined by delay dispersion of the comparator and the accuracy of the time-to-digital converter (TDC) comprising the levelcrossing ADC. With the pico-seco...

While process technologists are obsessed to follow Moore’s curve down to nanoscale dimensions, design technologists are confronted with gigascale complexity. On the other hand, post-PC and post dotcom products require zero cost, zero energy yet software programmable novel system architectures to be sold in huge volumes and to be designed in exponentially decreasing time. How do we cope with the...

The process of land use change and urban sprawl has been considered as a prominent characteristic of urban development. This study aims to investigate urban growth process in Bandar Abbas city, Iran, focusing on urban sprawl and land use change during 1956-2012. To calculate urban sprawl and land use changes, aerial photos and satellite images are utilized in different time spans. The results d...

BACKGROUND Idiopathic hypercalciuria is an important cause of symptoms related to the urinary system. The urinary excretion of high sodium and low potassium is a risk factor for hypercalciuria and urolithiasis. The aim of this study was to compare the urinary excretion of sodium and potassium by children older than two with idiopathic hypercalciuria and healthy control children in Bandar-Abbas,...

This paper deals with the puzzle of sentences like (i.a), which denies (i.b). (i) a. The King of France is not bald, because there is no King of France. b. The King of France is bald. In previous analyses of such examples two problems are often overlooked: the first is that (i.a) is supposed to express denial of (i.b) specifically on the grounds that the existence of a King of France is its pre...
