Geological noise removal in geophysical magnetic survey to detect unexploded ordnance based on image filtering
This paper describes the application of three straightforward image-based filtering methods to remove the geological noise effect which masks unexploded ordnances (UXOs) magnetic signals in geophysical surveys. Three image filters comprising of mean, median and Wiener are used to enhance the location of probable UXOs when they are embedded in a dominant background geological noise. The study ar...
متن کاملa new approach to credibility premium for zero-inflated poisson models for panel data
هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولA numerical approach to solve eighth order boundary value problems by Haar wavelet collocation method
In this paper a robust and accurate algorithm based on Haar wavelet collocation method (HWCM) is proposed for solving eighth order boundary value problems. We used the Haar direct method for calculating multiple integrals of Haar functions. To illustrate the efficiency and accuracy of the concerned method, few examples are considered which arise in the mathematical modeling of fluid dynamics an...
متن کاملtepe ghabristan: geophysical survey report
in march 2004, a fluxgate gradiometer survey was conducted over tepe ghabristan, covering approximately 6ha of ground. it identified further areas of the iron age cemetery with possible grave pits (areas b and c). in addition, an irrigation channel was discovered which could be contemporary to these iron age graves (area d). the anomalies in area e can be interpreted as buried structural remain...
متن کاملKinematic modelling of disk galaxies I. A new method to fit tilted rings to data cubes
This is the first of a series of papers in which the kinematics of disk galaxies over a range of scales is scrutinised by employing spectroscopy. A fundamental aspect of these studies is presented here: the new publicly available software tool TiRiFiC (http://www.astro.uni-bonn.de/ ̃gjozsa/tirific.html) enables a direct fit of a “tilted-ring model” to spectroscopic data cubes. The algorithm gene...
