Determination of light levels in a flat bed scanner using a gelatin-bromide photographic paper
The amount of light received by a document during a scanning or photocopying process has been addressed in different papers. The purpose of this study is to propose an alternative way to evaluate the irradiation that reaches the surface of the documents during these operations measuring the density produced on a photographic paper during the scanning. This method, requiring a densitometer and a...
متن کاملElectrospinning Nanofibers Gelatin scaffolds: Nanoanalysis of properties and optimizing the process for tissue engineering functional
Electrospinning has been recognized as an efficient technique for the fabrication of polymernanofibers. Recently, various polymers have successfully been electrospun into ultrafine fibers.Electrospinning is an extremely promising method for the preparation of tissue engineering scaffolds.In this study, nanofibers gelatin was electrospun at 20% v/v optimized content. To produce...
متن کاملUndesired light in a reconstructed hologram image caused by the nonlinearity of the photographic process.
Theory and experiment show that for a hologram object of two or more object points, the nonlinearity of the photographic process causes reconstructed images in addition to both the desired reconstructed image and the higher order reconstructed images. It is theoretically and experimentally shown that for a plane object parallel to the hologram plane, some of these undesired images may be focuse...
متن کاملOf the Recent Advances in Our Knowledge of the Photographic Process
While many materials are sensitive to light and can be used for making photographs, the present art of photography is based upon one specific process : The light-sensitive material is silver bromide in the form of extremely small crystals held in a layer of gelatin. These crystals are very sensitive to light when the reaction to light is made manifest by the process of development, that is, by ...
متن کاملمازاد سرمایه در زمان ورشکستگی در مدل ریسک کلاسیک با عامل اغتشاش on the surplus prior to ruin in the perturbed classical risk process
هدف این تحقیق در نظر گرفتن مدل ریسک کلاسیک که با عامل فرآیند وینر ، به مدل ریسک کلاسیک با عامل اغتشاش تبدیل می شود. در این تحقیق فرمول هایی صریح برای تابع چگالی احتمال توام و حاشیه ای مقدار مازاد سرمایه بلافاصله قبل و در زمان ورشکستگی و همچنین تابع چگالی احتمالی برای مقادیر و اندازه خسارت هایی که باعث ورشکستگی شده اند، بررسی می شود. نیاز برای چنین تحقیقی بدین سبب احساس می شود که در مدل ریسک کل...
