Upgrade of the HadGEM3-A based attribution system to high resolution and a new validation framework for probabilistic event attribution
Publication ID: pub.1103680958
Keywords: Atmospheric and Land Model; Climate of the 20th Century Plus (C20C+) Project; Ensembles; Forcings Set; Global; HadGEM3-A Based Attribution System; MET Office; Model Performance; Probabilistic Attribution; Resolution; Upgrade; Validation Framework
We present a substantial upgrade of the Met Office system for the probabilistic attribution of extreme weather and climate events with higher horizontal and vertical resolution (60 km mid-latitudes and 85 vertical levels), the latest Hadley Centre atmospheric and land model (ENDGame dynamics with GA6.0 science and JULES at GL6.0) as well as an updated forcings […]
Heating in Great Britain: An incumbent discourse coalition resists an electrifying future
Publication ID: pub.1130180824
Keywords: Coalition; Discourse; Gas; Great Britain; Heat; Incumbency; Power; UK
The power of incumbent actors to affect sustainability transitions is increasingly recognised as a central issue associated with systemic change. However, incumbent’s approaches and the outcome of their influence is rarely examined in academic literature. Using a novel approach which combines the lens of ‘discourse coalitions’ with an explicitly critical discursive stance, in which the […]
System-focused risk identification and assessment for disaster preparedness: Dynamic threat analysis
Publication ID: pub.1001796684
Keywords: Critical Human Activity Systems; OR in Disaster Relief; Qualitative System Dynamics; Risk Analysis; Risk Management
Current approaches to risk management stress the need for dynamic (i.e. continuous, ongoing) approaches to risk identification as part of a planned resource application aimed at reducing the expected consequences of undesired outcomes for the object of the assessment. We contend that these approaches place insufficient emphasis on the system knowledge available to the assessor, […]
Performance assessment and life cycle analysis of potable water production from harvested rainwater by a decentralized system
Publication ID: pub.1093011632
Keywords: Decentralized; Exeter; Life Cycle Analysis; Potable Water Production; Rainwater Harvesting; UK; University of Exeter
Decentralized rainwater harvesting (RWH) from roof runoff can complement the centralized supply of mains (drinking) water for a range of contexts, to assist in alleviating issues of water security. However, treatment to potable standard of harvested rainwater is not widespread. Consequently a comparative life cycle analysis (LCA) of decentralized and centralized potable water supply has […]
Performance analysis of robust stable PID controllers using dominant pole placement for SOPTD process models
Publication ID: pub.1100748123
Keywords: Control Performance; Dominant Pole Placement; Gain/Phase Margin; Monaco; Monte Carlo; PID Controller Tuning; Robust Stable Controller; Second Order Plus Time Delay (SOPTD); Signal/System Norms; Stability Region
This paper derives new formulations for designing dominant pole placement based proportional-integral-derivative (PID) controllers to handle second order processes with time delays (SOPTD). Previously, similar attempts have been made for pole placement in delay-free systems. The presence of the time delay term manifests itself as a higher order system with variable number of interlaced poles […]
Introducing a localised spatio-temporal LCI method with wheat production as exploratory case study
Publication ID: pub.1030104323
Keywords: Cornwall; Helford; Life Cycle Assessment; Life Cycle Inventory; Spatio-temporal Model; UK
The use of dynamical information, which is temporally and spatially explicit, to quantify environmental impacts is gaining importance in recent years. Life Cycle Assessment has been applied to identify environmental impacts of, for example, wheat production. However, conventional Life Cycle Assessment is typically limited by its static nature and cannot explicitly consider temporal and spatial […]
