Background and Objectives: In recent years, new technologies have led to produce a large amount of data and in the field of biology, microarray technology has also dramatically developed. Meanwhile, the Fisher test is used to compare the control group with two or more experimental groups and also to detect the differentially expressed genes. In this study, the false discovery rate was investiga...
Grid computing environments include heterogeneous resources shared by a large number of computers to handle the data and process intensive applications. In these environments, the required resources must be accessible for Grid applications on demand, which makes the resource discovery as a critical service. In recent years, various techniques are proposed to index and discover the Grid resource...
The Web has become the most important information source for most of us. Unfortunately, there is no guarantee for the correctness of information on the Web. Moreover, different websites often provide conflicting information on a subject. Several truth discovery methods have been proposed for various scenarios, and they have been successfully applied in diverse application domains. In this paper...
Present study was designed to investigate the effects of three teaching- learning approaches including discovery, interactive and transmission approaches on the students learning performance in biology lesson. In this quasi- experimental research three experimental groups (N1=60, N2=71, N3=63) were used in order to identify any significant difference between the students learning performance wh...
aims of religion are goals that the god perused in all of orders or large number of these. basis end of the aims of religion is proving the basis and general of religion to use of these to inference religious rules. it should be prove certitude of these aims to receive to this end. but because certitude of the religion aims direct relation to detection methods of their discovery, should be prov...
the discovery of the antifertility activity of gossypol led scientists and researchers to the development of compounds with antifertility activity that can be used as male contraceptives. these studies resulted in discovery of the antifertility activity of several classes of compounds which have been reported in the literature. this article deals with the synthesis of four new analogues of pyri...
ارزیابی مزایای استفاده از پدیده ی زمان پرواز در تصویربرداری سه بعدی pet با استفاده از روش مونت کارلو
همانند اغلب سیستمهای تصویربرداری، کارآیی و کیفیت تصاویر در pet نیز با نویز آماری محدود شده است. با محاسبه دقیق زمان ورود دو فوتون با انرژیkev 511 در حلقه آشکارسازهای دور بیمار، مکان نابودی قابل محدود شدن در یک بازه است. این تکنیک که به طور قابل ملاحظه ای می تواند نویز آماری در مقادیر بازسازی شده را کاهش دهد، tof pet نامیده می شود. تعدادی دوربین pet با توانایی اندازه گیری tof در دهه 80 میلادی سا...
content discovery is one of the fundamental issues that determines the architecture and performance of content distribution networks based on peer-to-peer (p2p) networks. to administrate the costs and discoveries, peers of a p2p network communicate with each other by one or more overlay layers. the condition of node’s relations in overlay networks, have a great impact in efficiency of networks....
A challenge for organizations is to manage electronic information without exposing the organization to sanctions in a later lawsuit. Since organizations do not usually voluntarily disclose internal information, the recent amendments to the Federal Rules of Civil Procedure, applicable to the discovery process, can compel an organization to permit an examination of electronically stored informati...
The rules of civil procedure in common law countries have been amended to better deal with the requirements of electronic discovery. One of the key changes in case management is the scheduling of a meet-and-confer session where the parties to litigation must meet early in the case before any discovery procedures have begun to exchange information regarding the nature, location, formats, and per...
