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 […]

The black box of power in polycentric environmental governance

Publication ID: pub.1117367644

Keywords: Environmental Governance; Global; Polycentric Governance; Power

Failure to address unsustainable global change is often attributed to failures in conventional environmental governance. Polycentric environmental governance—the popular alternative—involves many centres of authority interacting coherently for a common governance goal. Yet, longitudinal analysis reveals many polycentric systems are struggling to cope with the growing impacts, pace, and scope of social and environmental change. Analytic […]

Effects of slag substitution on physical and mechanical properties of fly ash-based alkali activated binders (AABs)

Publication ID: pub.1114222784

Keywords: Alkali Activated Cement; Fly Ash; Granulated Blast-furnace Slag; Microstructure; Mixture Proportioning; UK

Neat fly ash-based alkali activated binders require high activator dosages and high temperature curing in order to develop satisfactory mechanical properties. Blending ground granulated blast furnace slag (GGBS) with fly ash can give medium to high strengths without the need for high temperature oven curing. An extensive investigation was carried out for understanding the effects […]
