six-sigma has some measures which measure performance characteristics related to a process. in most of the traditional methods, exact estimation is used to assess these measures and to utilize them in practice. in this paper, to estimate some of these measures, including defects per million opportunities (dpmo), defects per opportunity (dpo), defects per unit (dpu) and yield, a new algorithm ba...

the rapid scaling in modern cmos technology has motivated the researchers to design new analog-to-digital converter (adc) architectures that can properly work in lower supply voltage. an exchanging the data quantization procedure from the amplitude to the time domain, can be a promising alternative well adapt with the technology scaling. this paper is going to review the recent development in t...

    Six sigma,   Rolled throughput yield, Organizational performance Six Sigma is a well- established approach to improve the capability of business processes in order to gain satisfaction of customers. The performance assessment of a given process is essential to some phases of six sigma methodology. So far, different indicators are used to demonstrate the performance of a process, while many ...

section was performed by myself and the volvulus again reduced. To prevent a recurrence of the twisting, the colon was stitched to the abdominal parieties. It was greatly liypertrophied and harboured a mass of constipated feces which probably caused the volvulus. The patient gave a history of long continued obstinate constipation. He returned again in the following March when I performed abdomi...

"Some patients again are met with, whether in private or hospital practice, who either before or since the excision operation, are quite incapable, and cannot by any surgical method be made capable of wearing an artificial eye even if they desire it; such are the cases of irregular cicatrization within the lids caused by wounds or burns or ill surgery and producing obstinate entropion, strong c...

‎The symmetric doubly stochastic inverse eigenvalue problem (hereafter SDIEP) is to determine the necessary and sufficient conditions for an $n$-tuple $sigma=(1,lambda_{2},lambda_{3},ldots,lambda_{n})in mathbb{R}^{n}$ with $|lambda_{i}|leq 1,~i=1,2,ldots,n$‎, ‎to be the spectrum of an $ntimes n$ symmetric doubly stochastic matrix $A$‎. ‎If there exists an $ntimes n$ symmetric doubly stochastic ...
