Optimal pathway towards building EPC rating improvements align with building energy performance certificate programme
… efficiently adopting Energy Efficiency Measures (EEMs). With buildings contributing approximately 40\% of global energy consumption and 36\% of carbon dioxide emissions, enhancing energy performance is critical. EPCs have been introduced globally to assess and promote energy efficiency in …

Effect of harmonics on the efficiency of a three phase energy efficient and standard motors
… and the economics of energy efficient motors (EEMs) and standard motors (STMs). In this research, the skin effect impedance model that incorporates the skin effect in the rotor bars is used to study the motor’s behavior under harmonics. The characteristic behavior of the motors are simulated …

Dissolved organic material in groundwater and application of fluorescence spectroscopy coupled with EEM PARAFAC models as a means of site characterisation
… Analysis of excitation emission matrices (EEMs) and absorption data demonstrated that the increased DOC and an increase in relative molecular weight of dissolved organic matter (DOM) was likely due to biofilm shearing. The fourth stage split a set of EEMs from the research site, based on …

Spatio-temporal characterization of a complete algal bloom event using fluorescence spectroscopy in tandem with conventional physico-chemical methods
… and 3-D excitation emission matrixes (EEMs) in a waterbody experiencing an algal bloom with intensive monitoring. Furthermore, the correlations between the EEMs and other physical and chemical parameters of blooms have not been elucidated till date. The Milford Gathering Pond in Geary …

Organic matter fluorescence properties of some U.K. fresh and waste waters
… and effluent fluorescent organic matter using EEMs. I identify the likely origins and bioavailability of common fluorophores and the applicability of fluorescence as a technique for measuring the polluting potential of organic carbon in waters. I also determine changes in sample character and …

Improving operational effectiveness of Tactical Long Endurance Unmanned Aerial Systems (TALEUAS) by utilizing solar power
… of an Electrical Energy Management System (EEMS) that safely collects and distributes the energy onboard. The electrical energy is supplied by the semi-rigid mono crystalline silicon solar cells, which are embedded into the skin of the glider’s wings without distorting the airfoil. To …

Straight pipes and household wastewater discharges into the rural Alabama and impact on watershed water quality with wetland land-uses
… parameters. Excitation-emission matrixes (EEMs) Parallel Factor Analysis (PARAFAC) was used to identify and classify fluorescence emitting organic substances based on fluorescence peak location. Three fluorescence components, terrestrial humic-like, microbial humic-like, and protein-like …

Total N-nitrosamine Precursor Adsorption with Carbon Nanotubes: Elucidating Controlling Physiochemical Properties and Developing a Size-Resolved Precursor Surrogate
… water fluorescence excitation-emission matrices (EEMs). TONO precursor surrogates were discovered, capable of predicting changes in TONOFP in WWTP samples that have undergone oxidation (R2 = 0.996) and sorption (R2 = 0.576). Importantly, both surrogates only require just 2 mL of sample volume to …

Comprehensive Analysis of Effluent Organic Matter from Five Wastewater Treatment Plants in Connecticut and Comparison to Natural Organic Matter
<p>Natural organic matter is an important driver of biotic and abiotic processes in aquatic environments. Wastewater treatment plants discharge a substantial amount of organic matter into the environment; however effluent organic matter has not been well studied. In this study, traditional organic …

The terrestrial carbon cycle in transition: tracking changes using novel tracers on multiple timescales
Soils store more carbon than the atmosphere and terrestrial vegetation combined, therefore, changes in soil carbon storage can affect the global carbon budget. One of the forms in which carbon is exported from soil is as dissolved organic carbon (DOC). Upon release from soil, components of DOC can …

Behaviour of trace organics and dissolved organic matter in granular activated carbon filters for drinking water supply
Granular and biological activated carbon (GAC and BAC) filters are widely used to remove organic compounds from drinking water sources during municipal drinking water treatment. Common uses of GAC filters include removal of taste and odour (T&O) causing compounds such as geosmin and …
