OBJECTIVE The aim of this study was to evaluate the left ventricular (LV) functional parameters calculated using quantitative electrocardiography (ECG)-gated myocardial perfusion single photon emission computed tomography (QGS). In addition to LV systolic parameters, diastolic parameters were compared with those by ultrasound echocardiography (UCG) and also with plasma B-type natriuretic peptid...

Many types of events such as concerts, festivals or sports events are spatially spread out, and user generated content (UGC) can be used to complement traditional broadcast capture. We address the issue of integrating user generated live streams into production environments by performing automatic content selection based on quality metadata. We demonstrate a system for capturing content togethe...

Abst_~'act ~hrlication Categorial Gtmmnar (t/:G) combines the syntactic iu.,;ights of Categoria[ Grammar with the semantic insights of I)i;course Representation Theory. The addition of uni/ication to these two frameworks allows a simple account of intexaction be,.wcen different linguistic levels within a constraining , monostraml theory. The resulting, computationaUy efticient, system provides ...

This study aimed to explore the dynamic variations of rumen fermentation characteristics and bacterial community composition during a 24 h in vitro fermentation. A total twenty-three samples were collected from original fluid (ORF, n = 3), at 12 (R12, 10), (R24, 10). Results showed that gas production, concentrations microbial crude protein, ammonia nitrogen, individual volatile fatty acids (VF...

The rise of user-generated content (UCG) as a source of information in the journalistic lifecycle is driving the need for automated methods to detect, filter, contextualise and verify citizen reports of breaking news events. In this position paper we outline the technological challenges in incorporating UCG into news reporting and describe our proposed framework for exploiting UGC from social m...

The underground coal gasification (UCG) technology converts into product gas and provides the option of environmentally economically attractive mining. Obtained syngas can be used for heating, electricity, or chemical production. Numerous laboratory trials have been performed in academic industrial fields. Lab-scale tests provide insight processes involved with UCG. Many UCG on ex situ reactors...

پایان نامه :وزارت علوم، تحقیقات و فناوری - دانشگاه یزد - دانشکده معدن 1390

روش ucg (گاززایی درجا از زغالسنگ در زیر زمین) در چند سال اخیر مجددا مورد توجه قرار گرفته است. این روش هنوز در کشور ما اجرا نشده و شناخت دقیق و کاملی از آن وجود ندارد. در این پایان نامه سعی شده ضمن معرفی و ارائه تاریخچه ucg روشهای مختلف در اجرای آن نیز به اختصار تشریح شود. در ادامه با انتخاب یک ناحیه (ناحیه زغالی تخت) به عنوان مورد مطالعاتی به تحلیل پایداری فضاهای استخراجی بین چاه های تولید و تز...

با وجود اینکه ایران از نظر برخورداری از منابع زغال سنگ در جایگاه دوازدهم جهان قرار دارد اما این منبع عظیم انرژی، تنها یک درصد در سبد انرژی کشور سهم دارد. در ایران، اقتصاد انرژی تحت تاثیر ذخایر نفت و گاز طبیعی قرار دارد و این موضوع سبب شده به منابع دیگر انرژی که سودآوری کلانی دارند، توجه چندانی نشود. فناوری نوین گاز کردن زیرزمینی زغال­سنگ (ucg) روشی برای تبدیل زغال­سنگ به گاز در زیرزمین است که س...

Underground coal gasification (UCG) is a clean mining technology without significant environmental impacts. This can also be used in deep, hard-to-reach seams or deposits affected by tectonic disturbances, where conventional impossible. Several techniques and methods have been investigated worldwide to support the process control of UCG. Global research focuses on UCG operating parameters stabi...
