Fundamentals of Noble Gas Thermochronometry

The ideal geochronometer would be a universally stable phase that quantitatively retains both parent and daughter isotopes. Though a few mineral systems such as zircon U-Pb dating come reasonably close to this ideal, most minerals are incompletely retentive of daughterproduct nuclides under crustal conditions. The mechanisms by which the daughter product can be lost from minerals include dissol...

hazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures

شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...

Working paper Weather, Storage, and Natural Gas Price Dynamics: Fundamentals and Volatility

This paper assesses how market fundamentals affect asset return volatility by drawing on evidence from the U.S. natural gas futures market. One of the novel features of this paper is the use of the deviation of temperatures from normal (weather surprise) as a proxy for demand shocks and a determinant of the conditional volatility of natural gas futures returns. I estimate a GARCH model using da...

Fundamentals of Pedestrian and Evacuation Dynamics

Multi-Agent Simulation is a general and powerful framework for understanding and predicting the behaviour of social systems. Here we investigate the behaviour of pedestrians and human crowds, especially their physical movement. Our aim is to build a bridge between the multi-agent and pedestrian dynamics communities that facilitates the validation and calibration of modelling approaches which is...
