Fractal Metrology for biogeosystems analysis

Evaluation of fractal dimensions for analysis of aggregate stability

Fractal Metrology for images, signals and time series processing in Geosciences

The comparative study of Geosystems fractal behavior requires harmonizing statistics and integral information management. A core set of fractal parameters extracted from multiscale images and time series, as well as by signal processing, is uncertain, scale and measurement algorithm dependent, dynamic and variable in space. The aim of our research is to standardize the polifacetic information c...

analysis 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...

Geometrical Specification Model for Gear - Expression, Metrology and Analysis

To ensure the gear precision, industries need a coherent model to express, to analyse and to check geometrical specifications. Most gear tolerance representations are directly driven by the convenience of dimensional metrology and not by the convenience of the set of activities of the tolerancing process. Therefore, to ensure the coherence of all tolerancing process activities, there is a neces...

Metrology and Quantitative Analysis in ISO 15939

Measurement based on international standards for measurement (i.e. metrology) is not the same as the judgment-based quantification of implicit relationships across a mix of entities and attributes without due consideration of admissible mathematical operations on numbers of different scale types. This paper analyzes the Measurement Information Model in ISO 15939 and clarifies what in it refers ...
