در فرایند نورد سرد فویلها، با توجه به ضخامت بسیار کم آنها (کمتر از ?m 50) از تغییر شکل الاستیک غلتکها در برابر تغییر ضخامت ورق نمی توان صرفنظر کرد. بنابراین با در نظر گرفتن سیستم فویل و غلتک به عنوان یک سیستم فنر با ضریب سختی متغیر در طول ناحیه کاری و استفاده از تنشهای تماسی هرتز می توان این تغییر شکل را به دست آورد. از طرف دیگر کاهش ضخامت در فویلها احتیاج به نیروی نورد بالایی دارد که برای کاهش...
As software systems become larger and more complex, developers require the ability to model abstract concepts while ensuring consistency across the entire project. The internet has changed the nature of software by increasing the desire for software deployment across multiple distributed platforms. Finally, increased dependence on technology requires assurance that designed software will perfor...
Date syrup powder is a new product which can be used as sugar substitute. First, the date syrupwas spread out on a foil and placed in the oven at 60°C for 24 hours. Date syrup was separated from the foil andgrinded. 2% agar and 2% starch were added and syrup with agar and starch that was in a lumpy shape werecrushed and spread on the foil and placed at 60°C for 24 hours. Powdered granules, agar...
This paper is concerned with FS-FOIL—an extension of Quinlan’s First-Order Inductive Learning Method (FOIL). In contrast to the classical FOIL algorithm, FS-FOIL uses fuzzy predicates and, thereby, allows to deal not only with categorical variables, but also with numerical ones, without the need to draw sharp boundaries. This method is described in full detail along with discussions how it can ...
In this paper, we aim to understand whether current language and vision (LaVi) models truly grasp the interaction between the two modalities. To this end, we propose an extension of the MSCOCO dataset, FOIL-COCO, which associates images with both correct and ‘foil’ captions, that is, descriptions of the image that are highly similar to the original ones, but contain one single mistake (‘foil wo...
The extent to which Chinese is represented phonologically or orthographically in verbal short-term memory was investigated using a short-term cued recall task (Tehan & Humphreys, 1998). In all conditions, proactive interference was induced by providing a retrieval cue (e.g. wild animal) that subsumed a to-be-recalled target word (e.g. leopard) and a to-beforgotten foil word (e.g. tiger), so tha...
there is a complicated relation between cold flat rolling parameters such as effective input parameters of cold rolling, output cold rolling force and exit thickness of strips. in many mathematical models, the effect of some cold rolling parameters has been ignored and the outputs have not a desirable accuracy. in the other hand, there is a special relation among input thickness of strips, the ...
the forging model for cold rolling is one of rolling models that is used in rolling calculations. in this model,the final rolling pressure is an average value and it is not an accurate model.also by using this model,the firction hill curves are plotted due to the central point of the rolling bite length while frictional stresses intersect at the neutral point.in this study, a new model based on...
strip tearing during cold rolling process has always been considered among the main concerns for steel companies. several works have been done so far regarding the examination of the issue. in this paper, experimental data from cold rolling tandem mill is used for detecting strip tearing. sensors are placed across the cold rolling tandem mill. they receive information on parameters (such as ang...
