Abstract:

Permanently sequestering carbon dioxide (CO2) in gas-bearing shale formations is beneficial in that it can mitigate greenhouse gas emissions as well as enhance gas recovery in production wells. This is possible due to the sorption properties of the organic material within shales and their greater affinity for CO2 over methane. The phenomenon of preferentially adsorbing CO2 while desorbing methane has been proven in coalbed reservoirs successfully, and is feasible for shale formations. The objective of this thesis is to explore the potential for enhanced gas recovery from gas-bearing shale f

Abstract:

Acute indoor concentrations of benzene and ethanol were evaluated in the California Polytechnic State University San Luis Obispo’s pilot winery workroom. Air samples were collected during four different wine-making activities: fermentation, fermentation with Brix content testing, post-alcoholic fermentation pressing, and storage/finishing. Average workroom benzene concentrations ranged from 0.05 to 0.12 mg/m3. Ethanol concentrations in the winery workroom varied with the activity, ranging from 0.9 to 12 mg/m3. Pressing and fermentation with Brix content testing both led to higher indoor ethano

Abstract:

The major part of mountain drainage networks is formed by high gradient channels and their nature and dynamics affect the features of sediment delivered to downstream channels, determining the quantity, timing and size of material transported by lowland rivers. Bedload is the transport process that regards the coarser particles, that are mobilized by rolling, sliding and saltating on the channel bed. In mountain environments, the analysis and quantification of bedload transport is of fundamental importance for hazard assessment, understanding the morphodynamics of higher order channels, planni

Abstract:

This thesis contributes work to the fields of runtime monitoring and specification mining. It develops a formalism for specifying patterns of behaviour in execution traces and defines techniques for checking these patterns in, and extracting patterns from, traces. These techniques represent an extension in the expressiveness of properties that can be efficiently and effectively monitored and mined. The behaviour of a computer system is considered in terms of the actions it performs, captured in execution traces. Patterns of behaviour, formally defined in trace specifications, denote the traces

This has created a challenge for the CMS collaborators in terms of data storage for analysis. To store only the interesting physics data the readout rate has to be reduced to 100 Hz where the data has to be ltered through a monitoring system for quality checks.

Hair has a number of advantages over more conventional sample types, such as serum, whole blood and urine, as an indicator of the intake and exposure to trace elements. While the analysis of these conventional sample types can only be used as a measure of recent exposure, hair, in contrast, can provide an historical record of exposure episodes. Furthermore the levels of trace elements in hair are higher than in blood and as a result small changes in intake are magnified. In addition, the collection of hair samples is non-invasive and the samples are easy to store. However, the difficulty in di

Soil erosion is a global problem, affecting much of the world’s agricultural land. As the world’s population increases, the pressures placed upon the land resource to provide space for food production, leisure, housing and industrial facilities also increases. Thus it is vital that the land resource is as productive as possible. As soil erosion is the major cause of soil degradation globally, it is vital that methods for accurately monitoring the degree of erosion from a site, and the effectiveness of any remediation attempts are available.

Abstract:

During the past decade, carbon capture, utilization, and storage (CCUS) has gained considerable recognition as a viable option to mitigate carbon dioxide (CO2) emissions. This process involves capturing CO2 at emission sources such as power plants, refineries, and processing plants, and safely and permanently storing it in underground geologic formations. Many CO2 injection tests have been successfully conducted to assess the storage potential of CO2 in saline formations, oil and natural gas reservoirs, organic-rich shales, and unmineable coal reservoirs.

Abstract:

Voltammetry is one of a few analytical methods, suitable for on-line monitoring of trace metals and is sufficiently sensitive in the low μg/L range for this purpose. The advantages of in-situ use of voltammetry are low cost and no or minimal sample change, since the sample is taken automatically and analysis is performed immediately without a need to collect a sample manually risking contamination and metal loss. Automatic monitoring is essential to record the natural variations of metal concentration in natural or industrial water and registration of accident due to natural or anthropogenic r

Abstract:

A new approach to the evaluation of the reliability of electrical systems is presented. In this approach a Graph Trace Analysis based approach is applied to integrated system models and reliability analysis. The analysis zones are extended from the traditional power system functional zones. The systems are modeled using containers with iterators, where the iterators manage graph edges and are used to process through the topology of the graph. The analysis provides a means of computationally handling dependent outages and cascading failures. The effects of adverse weather, time-varying loads,

Abstract:

Clinicians are becoming increasingly aware of the effect of various pathologies on the characteristics of saccadic eye movements. As such, an efficient and non-invasive means of measuring eye-movement in a clinical environment is of interest to many. The aim of this thesis is to investigate the clinical application of a non-invasive eye movement recording technique as a part of a clinical examination. Eye movements were measured using an IRIS 6500 infrared limbal eye tracker, which we customized for the direct recording of oblique eye movements as well as horizontal and vertical. Firstly, the

Abstract:

The use of two online sensors, the S::CAN and the FLD, was used to evaluate the treatment of synthetic wastewater by UV/H₂O₂ advanced oxidation. The UV dose and intensity for the flow through reactor was also determined using H₂O₂ actinometry. The total power of the lamps in the reactor was determined to be 139 W which, with the absorbance of the water, produced a UV dose of 39.4 mJ/cm². It was determined that the S::CAN was unable to differentiate between treatment of a particular water, however it could differentiate between different test waters. The FLD was very sensitive and was able to d

Abstract:

Cette thèse a pour objectif d’évaluer la distribution spatiale et les origines d’éléments trace anciens et émergents dans les sols de Nouvelle-Aquitaine en se basant sur le Réseau de mesures de la qualité des sols (RMQS). En premier lieu, six éléments trace anciens ont été ciblés (As, Cd, Cu, Cr, Ni, Pb), leur distribution spatiale a été estimée à partir des analyses de 356 échantillons issus de la première campagne RMQS. Les concentrations médianes régionales retrouvées sont proches des valeurs nationales. La comparaison entre les vibrisses régionales et nationales comme valeurs seuils d’anom

Abstract:

A UV Laser Induced Fluorescence (LIF) system, previously developed in our laboratory, was modified and used for a series of applications related to the development and optimization of UV LIF spectroscopic measurements of trace contaminants in drinking water and other water sources. Fluorescence spectra of a number of water samples were studied, including those related to the reverse osmosis water treatment and membrane fouling, domestic and international drinking water, industrial toxins, bacterial spores, as well as several fluorescence standards. Of importance was that the long term detectio
