مقدمه: درعلم آمارسنتی همه پارامترها بوسیله مدلهای ریاضی ومشاهده های تجربی تعریف می شد. بعضی وقتها به نظر می رسد چنین فرضهایی برای مسائل زندگی روزمره سختگیرانه باشد.مخصوصا درصورتیکه ما با داده های زبان شناسی یا احتیاجاتی که صریح نباشند سرکارداشته باشیم. برای اینکه این مشکل را ازبین ببریم ازروش فازی استفاده می کنیم. تعریف مسئله: درمرحله اول از تحقیق درباره انواع مختلف از پدیده(زیستی-فنی-فیزیک...
self-centering pier (scp) has been viewed as a remarkable accomplishment which is able to sustain major lateral loading with reduced structure damage in seismic engineering. stiffness deterioration observed in experiment is vital for the seismic performance of self-centering concrete pier. in this contribution, the associated stiffness deterioration with respect to the structural damage is mode...
in this paper, a production inventory model is developed for the business enterprise which consists of three wings. the first wing is for manufacturing new items, the second wing is for collecting the returned items, while third wing is for remanufacturing the returned item. in this model we consider the fact that the storage item is deteriorated during storage periods and salvage value is inco...
conclusions male gender, history of hypertension, high nyha score, and the presence of cad predict lvef deterioration in patients with lbbb. objectives the present study aimed to identify underlying factors that predict left ventricular ejection fraction (lvef) deterioration in patients suffered from complete lbbb. patients and methods in a retrospective case-control study, the data of 220 cons...
critical, because true progressors require a change in treatment, but pseudoprogressors should continue with adjuvant temozolomide. Currently, there are no definitive radiologic criteria to differentiate between true progression and pseudoprogression. The response criteria for brain tumours developed by the Response Assessment in Neuro-Oncology Working Group state that apparent radiologic progr...
This paper presents a luminosity conserving and contrast enhancing histogram equalization method for color images. The histogram equalization is one of the ordinary methods employed for enhancing contrast in TV and images for consumer electronics where unwanted subjective deterioration are frequently occur. Although there have been many solutions to overcome the drawback of histogram equalizati...
The nature of the services provided by IP Multimedia Subsystem (IMS) networks require a maximum quality, this will appear in service provisioning for differentiate between the added value of IMS and other classical case as well as Internet. Toward, the QoS management mechanisms focus primarily on resource reservation in service provisioning, all this specification are introduced by 3GPP standar...
In this article, an inventory model is developed to deal with the impreciseness present in the market demand and the various cost parameters. The presented model is developed in crisp and fuzzy environments. Signed distance method is used for defuzzification. In most of the classical models, constant demand rate is considered. But in practice purchasing deeds of the customers is affected by the...
In this paper, with China's economic and social development, energy shortage and environmental deterioration has become an acute problem. The promotion of green public building, palys a veryimportant role for building a resourceconserving and environment-friendly society in China. This paper analysis on the connotation of value engineering and green public building, demonstrates the value engin...
In this paper, a supply chain model with power form stock-dependent demand rate is developed, incorporating the effect of learning and inflationary environment. In order to bring their research closer to reality, all the cost parameters involved in the model are considered fuzzy in nature. The demand rate is assumed to be a polynomial form of current inventory level in Own-warehouse. To display...
