A radix-based digital self-calibration technique for multistage analog-to-digital converter(ADC) is presented. This technique can correct errors due to capacitor mismatch and finite opamp gain. The equivalent radix of each stage is extracted by measuring the discontinuity on the ADC transfer curve and iteratively adjusting the equivalent radix to minimize this discontinuity. A much more accurat...

The stateless deterministic ordered restarting automata accept exactly the regular languages, and it is known that the trade-off for turning a stateless deterministic ordered restarting automaton into an equivalent DFA is at least double exponential. Here we present a construction that yields an equivalent NFA of size 2 from a stateless deterministic ordered restarting automaton that works on a...

The structural scheme of an electromagnetoelastic actuator for nano biomechanics is found. has difference in the visibility energy conversion from Cady and Mason electrical equivalent circuits a piezo vibrator. electromagnetoelasticity equation differential are solved to construct actuator. obtained by using reverse direct piezoelectric effects. transfer functions written

The Residue Number System (RNS) is suitable for DSP architectures because of its ability to perform fast carry-free arithmetic. However, this advantage is over-shadowed by the complexity involved in the conversion of numbers between binary to RNS representations and have prevented the widespread use of RNS. Converting a number from a binary representation to its RNS equivalent is known as forwa...

this study was done with the aim of investigating the kinetics of available phosphorus changes in treated soils with municipal solid waste compost, fertilizer and the mixture of these in two levels of first and second percent in eight calcareous soil samples and in a period of zero to 3600 hours in incubation conditions (fc moisture and 250c). the results showed that with time increasing, extra...

We investigated the applicability of the repairable-conditionally repairable (RCR) model and the multi-target (MT) model to dose conversion in high-dose-per-fraction radiotherapy in comparison with the linear-quadratic (LQ) model. Cell survival data of V79 and EMT6 single cells receiving single doses of 2-12 Gy or 2 or 3 fractions of 4 or 5 Gy each, and that of V79 spheroids receiving single do...

objective(s): this paper describes synthesispolyvinyl alcohol/caf2:er nanofibers because of  its  photoluminescence properties.materials and methods:  first, caf2:er nanocomposite synthesized with co-precipitation method. in order to prepare polyvinyl alcohol (pva)/caf2:er nanofibers, caf2:er nanocomposites were added to the polyvinyl alcohol (pva) polymer. pva/caf2:er composite nanofibers were...
