بحث عیب یابی ماشین آلات دوار یکی از موضوعات مهم و کاربردی در صنایع می باشد. تحلیل ارتعاشی قسمت های مختلف یک ماشین به عنوان ورودی یکی از روش های غیر مخرب و قابل اجرا در حین کار ماشین، روش مطمئن و ساده ای است که در بسیاری از موارد توصیه می شود. در این تحقیق پس از ساخت مدل ماشین دوّار چهار عیب متداول یعنی 1) نابالانسی 2) ناهمراستایی 3) خرابی یاتاقان 4) لقی مکانیکی را بطور جداگانه برروی دستگاه ایجا...

The disease-programming effects of a maternal low-protein (MLP) diet in rat pregnancy have been suggested to be attributable of hyperhomocysteinaemia. The aim of the present study was to determine whether MLP feeding impacted upon maternal and day 20 fetal homocysteine concentrations, with ensuing effects upon oxidant/antioxidant status. Sixty-four pregnant rats were fed either MLP diet or cont...

The Mlp (multicopy lipoproteins) family is one of many paralogous protein families in Borrelia burgdorferi. To examine the extent to which the 10 members of the Mlp family in B. burgdorferi strain 297 might be differentially regulated, antibodies specific for each of the Mlps were developed and used to analyze the protein expression profiles of individual Mlps when B. burgdorferi replicated und...

هدف از این تحقیق پیش بینی روند مصرف کاغذ چاپ و تحریر در ایران طی یک دوره زمانی 5 ساله با استفاده از روشهای کلاسیک و نوین پیش بینی است. به منظور انجام این پیش بینی، در ابتدا پیش بینی پذیر بودن سری زمانی با استفاده از آزمون های دوربین- واتسون و گردش مورد بررسی قرار گرفت. سپس به مقایسه مدل شبکه عصبی مصنوعی (پرسپترون چندلایه (mlp)) و مدل های کلاسیک تک متغیره و چندمتغیره از قبیل مدل های تک متغیره هم...

In this paper, we described and developed a framework for Multilayer Perceptron (MLP) to work on low level image processing, where MLP will be used to perform image super-resolution. Meanwhile, MLP are trained with different types of images from various categories, hence analyse the behaviour and performance of the neural network. The tests are carried out using qualitative test, in which Mean ...

The present paper deals with the continuous work of extending multi-dimensional limiting process (MLP) onto correction procedure via reconstruction (CPR). MLP, which has been originally developed in finite volume method (FVM), provides an accurate, robust and efficient oscillation-control mechanism in multiple dimensions for linear reconstruction. Recently, MLP has been extended into higher-ord...

The discrimination powers of Multilayer perceptron (MLP) and Learning Vector Quantisation (LVQ) networks are compared for overlapping Gaussian distributions. It is shown, both analytically and with Monte Carlo studies, that the MLP network handles high dimensional problems in a more eecient way than LVQ. This is mainly due to the sigmoidal form of the MLP transfer function, but also to the the ...

This paper presents a new derivation of Akcasu’s Modified Levermore-Pomraning (MLP) model for estimating the ensemble-averaged angular flux for particle transport problems in 1-D geometrically random media. The significant new feature of the MLP equations is that, unlike the earlier Levermore-Pomraning (LP) model, the MLP equations are exact for certain classes of problems with scattering.

Abstract A class of recurrent neural networks is developed to solve nonlinear equations, which are approximated by a multilayer perceptron (MLP). The recurrent network includes a linear Hopfield network (LHN) and the MLP as building blocks. This network inverts the original MLP using constrained linear optimization and Newton’s method for nonlinear systems. The solution of a nonlinear equation ...

Purpose We further optimized and evaluated the safety of the magnetic levator prosthesis (MLP) for temporary management of severe blepharoptosis, and compared efficacy and comfort against the ptosis crutch. Methods The interpalpebral fissure (IPF) of participants (n = 12) with ptosis was measured during attempted eyelid opening, volitional closing, and spontaneous closing with no device, ptos...
