Application of XRF, XRD, thermal analysis, and voltammetric techniques to the study of ancient ceramics.
An in-depth chemical-analytical study has been performed on biscuit and mortar from 17th-18th century tiles from a mediaeval hermitage in the province of Valencia (Spain). Representative samples were chosen from the tile fragments available, using appearance, essentially color and consistency, as the criterion. The chemical composition was analyzed by X-ray fluorescence of the samples in the fo...
متن کاملAn Evaluation of Xrd and Xrf Methods Used in an Aluminium Bath Analysis
The paper deals with the application of X-ray fluorescence and diffraction for the routing control of a chemical content of an electrolysis cell in aluminum reduction plants. Among two approaches XRD meets technological requirements on accuracy, time limit and the cost of analysis. XRF demonstrates insufficient accuracy because of sample preparation problem.
متن کاملStructural Characterization of Steatite Vessels of Shadyakh by XRF, XRD and SEM Techniques
Using the stones to make tools and vessels dated back to Paleolithic and Neolithic periods. Stones so called soft stones, along with the alabaster, are one of the most famous stones that have been used to produce vessel in Near East, where they are in use currently in different applications. Soft stone vessels reach to highest level of flourishing during the Bronze Age and its geographical exch...
متن کاملSimultaneous Xrd/xrf with Low-power X-ray Tubes
A test bench instrument constructed at MOXTEK, Inc. is capable of simultaneously capturing X-ray diffraction (XRD) and X-ray fluorescence (XRF) information using a charge-coupled device (CCD) as the X-ray detector. NASA is funding the instrument’s construction because of its low-power consumption and compact size; it could be used for in-situ planetary exploration missions for mineral analysis....
متن کاملanalysis of ruin probability for insurance companies using markov chain
در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
