BACKGROUND Standards for the reporting of factorial randomised trials remain to be established. We aimed to review the quality of reporting of methodological aspects of published factorial trials of complex interventions in community settings. METHODS We searched MEDLINE, EMBASE, PsychInfo and the Cochrane Controlled Trials Register to identify factorial randomised trials of complex intervent...
In predictive food microbiology, cardinal parameter models are often applied to describe the effect of temperature, pH and/or water activity on the microbial growth rate. To identify the model parameters, full factorial designs are often used, in spite of the high experimental burden and cost related to this method. In this work, the impact of the selected experimental scheme on the estimation ...
عملیات کشش عمیق یکی از کاربردی ترین روشهای شکل دهی ورقهای فلزی از گروه شکل دهی فلزات می باشد در این فرایند پارامترهای زیادی روی موفقیت فرایند و خواص قطعات تأثیر می گذارند. غیر از چین خوردگی و برگشت فنری یکی از عیوب اصلی قطعات در این فرایند، یکنواختی و کاهش ضخامت دیواره می باشد. که در نهایت می تواند پس از گلویی شدن منجرب به پارگی نیز گردد، کاهش ضخامت ورق در حین فرایند. خود به پارامترهای مختلف فر...
One of the problems in removing pollutants from water by photocatalytic methods is the separation of the catalyst from the solution. In this study, the catalyst stabilization method was used to solve this problem. Nano ZnFe2O4 supported on Copper Slag (CS) produced in this research is an environment-friendly, simple and cost-effective catalyst. ZnFe2O4</su...
Artificial neural networks have been used to support applications across a variety of business and scientific disciplines during the past years. Artificial neural network applications are frequently viewed as black boxes which mystically determine complex patterns in data. Contrary to this popular view, neural network designers typically perform extensive knowledge engineering and incorporate a...
