فرایند six sigma یکی از دست آوردهای مهم نظام مدیریت کیفیت جامع است که به طور فزاینده ای در شرکت های معتبر و موفق دنیا به کار گرفته شده است. این فرایند با تکیه بر اهداف زیر عمل میکند: ۱- رضایت مشتری ۲- تولید با خطای تقریبا صفر 3- صرفه جویی در منابع4- بازگشت سرمایه 5- نهادینه کردن کیفیت در سازمان 6-بهبود مستمر و حفظ فرایند بهبود شش زیگما به عنوان نوعی ابزار عملی قابل سنجش و تحلیل هوشمند، این امکا...
در این رساله به بررسی کران داری ضربگرهای لامبرت با برد عملگرهای ترکیبی روی فضاهای $l^p(sigma)$ می پردازیم. بر این اساس، برخی از ویژگی های عملگرهای امید شرطی را نسبت به زیرجبرهای $sigma$ از نوع صفر بررسی می کنیم. همچنین، به مطالعه ی عملگر ترکیبی وزن دار روی فضای فرم های دیفرانسیل اندازه پذیر می پردازیم. به علاوه، بعضی خواص این عملگرها مانند کران داری، تعلق به کلاس های به طور ضعیف ن...
In this note we characterize the compact weighted Frobenius-Perron operator $p$ on $L^1(Sigma)$ and determine their spectra. We also show that every weakly compact weighted Frobenius-Perron operator on $L^1(Sigma)$ is compact.
INTRODUCTION Health is an important dimension of welfare comparisons across individuals, regions and states. Particularly from a long-term perspective, within-country convergence of the health status has rarely been investigated by applying methods well established in other scientific fields. In the following paper we study the relation between initial levels of the health status and its improv...
Background: Sigma factors are proteins that regulate transcription in bacteria. Sigma factors can be activated in response to different environmental conditions. The rpoS (RNA polymerase, sigma S) gene encodes sigma-38 (σ38, or RpoS), a 37.8 kDa protein in Pseudomonas aeruginosa (P. aeruginosa) strains. RpoS is a central regulator of the general stress response and operates in both retroa...
in this research a three dimensional model is explained which simulate the oil spill behavior inseas. this model is the developed version of previous two-dimensional study of aghajanloo et al., 2013.because of three-dimensional nature of the oil dispersion/movement in water, this is a more realistic model of oil spill transport and fate in marine environment. the model is based on eulerian appr...
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...
Introduction: Health Care organizations, because of their special nature of Medical Services, impossibility of assessment by customers, and increasing of patients and customer expectation, have to apply different management approach. In recent decade Six Sigma has been considered as systematic and powerful to improve service quality and cost saving. Six Sigma is a statistical and systematic app...
