Mid-continent basin - methane emissions reconciliation: facility level emissions
Get PDFPresenter Dan Zimmerle, Energy Institute, Colorado State University; Principle Investigator: Dag Nummedal, Colorado School of Mines.Presented at the RPSEA Onshore Technology Workshop: Interactive Workshop Focusing on Emissions from Unconventional Resources Development Activity, May 26, 2016, Denver, CO.Summary of results methane emission reconciliation for facility-level emissions using several measurement techniques during a comprehensive measurement campaign in a mid-continent basin. Comparison of bottom up versus top down methodologies
METEC controlled test protocol: continuous monitoring emission detection and quantification
Get PDFThis testing will assess the performance of continuous monitoring (CM) systems which perform leak detection and quantification (LDAQ) under Single-Blind controlled release testing over a range of environmental conditions and emission rates. Testing will evaluate system-level performance measures including Probability of Detection and Detection Time. Additional metrics including accuracy and precision of localization and quantification estimates will be evaluated if applicable. Due to the dependence of methods on weather conditions, testing will require an extended period, typically months, with active emission and non-emissions periods to (1) allow each Experimental Design Point to operate for an extended duration, typically hours, and (2) assess performance across a wide range of meteorological conditions
METEC controlled test protocol: survey emission detection and quantification
Get PDFThis testing will assess the performance of survey methods which perform leak detection and quantification (LDAQ) under single-blind controlled release testing over a range of environmental conditions and emission rates. Testing will evaluate system-level performance measures including Probability of Detection and Detection Time. Additional metrics including accuracy and precision of localization and quantification estimates will be evaluated if applicable
Now I See: Video Supports for English Language Learners
Get PDFGeneral education teachers are often unprepared by teacher preparation programs and limited professional development opportunities to support English Language Learners (ELLs), despite the increasing number of ELLs entering US schools and the trend towards placing them in mainstream classrooms. Video resources offer one viable approach to supporting the language learning of ELLs, drawing upon theoretical frameworks such as dual-coding, constructivist theory, and sociocultural perspectives. This paper describes the use of video resources to assist general education teachers in effectively leveraging videos to support the language learning of ELLs in mainstream classrooms
