▼ An underlying assumption of contextual cueing experiments is that repetition of a display will elicit contextual cueing, irrespective of the particular arrangement of items in the display. However, there is reason to doubt this assumption; a number of display properties have been shown to predict response times in visual search experiments, including target eccentricity, target quadrant, visual crowding, and visual clutter. The effects of display properties may therefore limit the interpretability of contextual cueing effects that do not control for differences in these variables. Further, display properties may be linked to the memorability of a display. If this is the case, then it may be possible for displays with certain properties to facilitate or inhibit context learning, because such displays are more or less memorable. The present study sought to estimate the impact of the confounding influence of display properties on RTs in the contextual cueing task. A multiple regression analysis of a large contextual cueing data set confirmed that target eccentricity, target quadrant, and visual clutter impact response times in the contextual cueing task. The first simulation study showed that significant group-level contextual cueing effects are unlikely to arise in the absence of context learning. However, display properties can influence the size of effects analyzed at the level of individual displays. A second simulation study investigated a variety of parameters that may influence RTs in the contextual cueing task. Surprisingly, the strength of association between display properties and display memorability was not predictive of contextual cueing. However, the mean of the memorability score distribution, the probability of a learned display showing an effect, and the magnitude of the effect were all predictive of contextual cueing. Crucially, interactions between these variables suggest that contextual cueing may reflect small effects that occur somewhat frequently or larger effects that occur infrequently, but not somewhere in between.

Reference intervals (RIs) are sets of percentiles that outline the range of laboratory test results belonging to healthy individuals. They are essential for the interpretation of laboratory test results. A wide variety of factors affect the validity of RIs. Among them are the statistical methods used to estimate RIs. However, little investigation has gone into the effect that different statistical methods have on the resulting RIs. This is particularly needed as the complexity of paediatric data makes it difficult to estimate RIs. These difficulties, however, can be addressed using appropriate statistical techniques, provided that there is an outline of scenarios under which these techniques are truly “appropriate”. The objective of this thesis is to provide a thorough investigation into the effect of different statistical methods on RIs. A systematic review was first conducted with a focus on paediatric RIs. The results of this review revealed that critical analysis steps are often overlooked due to complicated paediatric data. Even though a guideline addressing the establishment of RIs is available, there is great heterogeneity in the statistical methods chosen to estimate paediatric RIs. An extensive simulation involving the three most commonly used approaches to estimate RIs (the parametric, non-parametric, and robust methods) was also conducted to investigate and compare the performance of the different methods. The simulation results show that, when data follows a Gaussian distribution, or close to it, the parametric method provides the best estimates. The non-parametric method did not provide the best estimates of RIs (compared to the parametric method) unless data was highly skewed and/or large sample sizes were used. In addition, the bias and MSE associated with the parametric method when data follows a Gaussian distribution was mathematically derived, which may lead to the development of a bias corrected and more precise approach in the future.

▼

In traditional meta-analysis, a random-effects model is used to deal with heterogeneity and the random-effect is assumed to be normally distributed. However, this can be problematic in the presence of outliers. One solution involves using a heavy tailed distribution for the random-effect to more adequately model the excess variation due to the outliers. Failure to consider an alternative approach to the standard in the presence of unusual or outlying points can lead to inaccurate inference. A heavy tailed distribution is favoured because it has the ability to down-weight outlying studies appropriately, therefore the removal of a study does not need to be considered. In this thesis, the performance of the t-distribution and a finite mixture model are assessed as alternatives to the normal distribution through a comprehensive simulation study. The parameters varied are the average mean of the non-outlier studies, the number of studies, the proportion of outliers, the heterogeneity and the outlier shift distance from the average mean. The performance of the distributions is measured using bias, mean squared error, coverage probability, coverage width, Type I error and power. The methods are also compared through an empirical study of meta-analyses from The Cochrane Library (2008). The simulation showed that the performance of the alternative distributions is better than the normal distribution for a number of scenarios, particularly for extreme outliers and high heterogeneity. Generally, the mixture model performed quite well. The empirical study reveals that both alternative distributions are able to reduce the influence of the outlying studies on the overall mean estimate and thus produce more conservative p-values than the normal distribution. It is recommended that a practitioner consider the use of an alternative random-effects distribution in the presence of outliers because they are more likely to provide robust results.

▼ A musculoskeletal model of the shoulder region, which uses kinematic data as an input an estimates muscle forces and joint loads as an output, can give valuable information on the pitching motion. This helps us to get more insight into the pitching motion and its biomechanical interactions and may also help in reducing the injury risk and increasing pitching velocity. Currently, there are three problems that impede proper simulations: the lack of proper kinematic recordings, the fact that maximum force of the model could be too limited and the extreme character of the motion. An experimental study was performed to create a dataset including upper limb kinematics and PCSA scaling factors to scale maximum force in the DSEM. An acromion cluster was used to track the scapula. PCSA scaling factors ranged from 1.11 to 2.02. Following the experimental study, a case study was performed simulating this dataset in the DSEM. During simulation, the main problem arose in the optimization of the clavicle and scapula angles relative to the thorax, because the optimized angles contained large jumps, which are not realistic. This impeded proper simulation, because the jumps in muscle length caused both unsolved frames in the kinematics as well as in the dynamic model. Using a soft constraint instead of a hard constraint reduced these jumps and allowed for a complete solution in the kinematic model and an increase in the number of frames solved by the dynamic model. PCSA scaling also increased the number of frames solved by the dynamic model, however still unsolved frames were present, even after extreme scaling. Because of a change in range of motion as reported for pitchers, optimum muscle length might be different. This has a large impact in the model. If this would be the case, scaling optimum muscle length is recommended. In addition, segment scaling used in combination with using the soft constraint is recommended to improve the match between input angles and optimized angles, while still being compatible to the model. To study the motion, the kinematic model of the DSEM was used to estimate muscle length and velocity for all muscles during the pitching motion. Comparing these values to the force-velocity and the active force-length relationship showed whether muscles were limited by one or both of these relationships to produce force. This was the case for the teres minor, triceps (all three heads), infraspinatus, anconeus and serratus anterior. The triceps showed a ‘stretch effect’, meaning shortening in the acceleration phase preceded by lengthening in the cocking phase. This means that there is a possibility for elastic energy to be stored for this muscle.

Indiana University-Purdue University Indianapolis (IUPUI)

There is a critical need for faculty, a shortage of clinical sites, and an emphasis on quality and safety initiatives that drive increasing use of simulation in nursing education. Debriefing is an essential component of simulation, yet faculty are not consistently prepared to facilitate it such that meaningful learning, demonstrated through clinical reasoning, occurs from the experience. The purpose of this exploratory, quasi-experimental, pre-test-post-test study was to discover the effect of the use of a simulation teaching strategy, Debriefing for Meaningful Learning (DML), on the development of clinical reasoning in nursing students. Clinical reasoning was measured in 238 participant students from a Midwestern university school of nursing taking an adult health course that uses simulation. Participants were assigned to either the experimental or control group where the DML was compared to customary debriefing using the Health Sciences Reasoning Test (HSRT) before and after the debriefing experience, and the Debriefing Assessment for Simulation in Healthcare©–Student Version (DASH©–SV) with four supplemental questions about the DML (DMLSQ) process, during the post-debriefing assessment. This research sought to understand if the DML debriefing strategy positively influenced the development of clinical reasoning skills in undergraduate nursing students, as compared to usual and customary debriefing. The data revealed that there was a statistical difference between total mean test scores measured by the HSRT. There was, additionally, statistical significance in the change in scores between pre-test and post-test for those who used the DML as compared to the control. There was also a difference in the student’s perception of the quality of the debriefing measured by the DASH©–SV with the DML rated statistically higher than usual debriefing. Finally, there was a significant correlation, demonstrated through regression analysis, between the change in HSRT scores and students’ perception of quality debriefing and the use of the DML. This study contributes to the growing body of knowledge about simulation pedagogy, provides tools for use in debriefing, and informs faculty on best practices in debriefing.

▼ The building envelope is one of the most important design parameters for determining how the indoor physical environment relates to thermal comfort, visual comfort, and even occupants’ working productivity. Thus, the building envelope significantly affects the energy usage of a building. In an effort to simultaneously consider and satisfy all of the various indoor comfort requirements, changing climatic conditions can generate conflicting conditions. Acclimated Kinetic Envelope (AKE) is a notion proposed in this research to address these types of situations. There have been a number of experimental designs and practices dealing with the potential benefits of AKE. However, there has yet to be a detailed comparison in terms of the various impacts on building energy, indoor comfort, and other human factors, especially in different climates. The general objective of this research was to evaluate AKE’s performance on energy usage and human factors, and compare that information to CEE's in office buildings in four different climatic zones. The research methodology had two key elements: energy simulations and mockup surveys. With respect to energy use, the research employed a parametric simulation to assess building heating and cooling loads, the effects of envelope assemblies, and the overall building energy use related to the two types of envelopes (AKE and CEE). With respect to human factors, the research adopted mockup tests and surveys to evaluate the visual qualities and human responses of the two types of blind systems strategies (AKE and CEE). This research determined the following: 1) Compared to the other referenced models, AKE technologies significantly reduced the heating and cooling loads and peak demands of buildings, even with regards to designs using highly-insulated glazing and walls, in the representative climates. 2) Kinetic windows played a more significant role in energy saving than other kinetic elements existing in the four representative climates; the savings were approximately twice as large as the savings from highly-insulated glazing. 3) Only cooling-dominated climate installations were able to obtain energy savings by setting up external movable blinds. 4) Mockup survey results showed that overall satisfaction with the visual quality created by external movable blinds was statistically higher than the satisfaction related to external static blinds. Similar trends were also found in the subjective responses to “Lighting Levels, Lighting Distributions, and Glare Sensation.” Advisors/Committee Members: Beltrán, Liliana O.

▼ Oxaliplatin is an anticancer drug widely used in cancer chemotherapy. This thesis evaluates whether a specific dose-banding scheme for oxaliplatin could replace the individual dosing method that is currently used in the oxaliplatin administration. Dose-banding was introduced into UK clinical practice in 2001, as it reduces delays in patients receiving their treatment and, through quality control and end-product testing, safeguards the infusion quality and patient safety. A range of studies were included in this thesis: an extended stability study on oxaliplatin infusions using a sequential temperature cycling design; studies on oxalate, a potential degradation product and metabolite of oxaliplatin which has been linked to oxaliplatin neurotoxicity and the development of an ex vivo pharmacokinetic (PK) simulation model to compare the effect of different oxaliplatin dosing methods on its therapeutic outcomes. The shelf-life of oxaliplatin infusions over a concentration range of 0.2 mg/mL – 0.7 mg/mL is extended to 84 days when stored at 2 – 8℃ plus a further 7 days after being left at room temperature (25℃) for 24 hours. This ensures the unused oxaliplatin infusions are safe to be re-issued to patients, which could reduce drug wastage. The oxalate study suggests that the dose-limiting neurotoxicity of oxaliplatin is unlikely to be directly related to the oxalate produced from oxaliplatin degradation in infusions or from the non-enzymic transformation of oxaliplatin in vivo because the oxalate levels from these routes are minor compared to the endogenous level. The safety and efficacy of dose-banding schemes was demonstrated by comparing the simulated PK characteristics gained from the ex vivo model. Dose-banding with the +10% maximum deviation was selected as the most promising dosing scheme for oxaliplatin. Finally, recommendations are made concerning the introduction of oxaliplatin dose-banding scheme into clinical practice, and on the benefits of harmonised dose-banding schemes.

▼ Many reservoirs are considered unsuitable candidates for Enhanced Oil Recovery. Surfactant-Foam flooding, also referred to as Low-Tension-Gas flooding, could be a solution to enhance the oil recovery in tight, saline or high temperature reservoirs. SF-flooding combines reduction of the oil-water interfacial tension by surfactant, with mobility control provided by foam. While coreflood experiments have been performed, no Surfactant-Foam model has been developed yet. Therefore, the objective of this research is to develop and evaluate a conceptual model for Surfactant-Foam flooding. Several available foam- and surfactant flooding models are analyzed. By comparing the various approaches, two models are selected based on the identified modelling objectives, model complexity and available experimental data. In this study a Surfactant-Foam model is developed that combines an implicit-texture foam model with a two-phase effective surfactant model. The model assumes foam is in local-equilibrium and correlates salinity and a minimum surfactant concentration with a lowered water-oil interfacial tension. The model does not explicitly model the micro-emulsion phase. Furthermore, the model includes surfactant adsorption and salt and surfactant dispersion. An attempt to model foam diversion with surfactant dispersion has been made, but results are limited due to numerical instability. For every coreflood the effective dispersion coefficient is determined by fitting the experimental effluent salinity data with a solution to the 1D advection-diffusion equation. The performance of the combined model is evaluated with a reservoir simulator. According to the simulation study the surfactant model affects the gas relative permeability through a correlation with the connate water saturation. The defined chemical connate water saturation always affects the gas mobility, either by reducing the gas relative permeability, or by minimizing the impact of the limiting capillary pressure. The results show that an experimentally applied salinity gradient, correlated with a decrease and increase in water-oil interfacial tension, cannot be modelled with capillary number dependent relative permeability curves. In this research it is assumed that the water-oil interfacial cannot increase, after it achieved an ultra-low value. According to the current desaturation approach, oil prefers to flow in the presence of water in stead of gas at ultra-low interfacial tension. More research is required to investigate if this can be related with physics, or if it is purely a modelling artifact. Furthermore, the simulation study shows that the foam matching parameters of the implicit-texture model require optimization for cores with a mutual difference in connate water saturation, due to variation of the impact of the limiting capillary pressure. Simulations are performed to history match experimental data and are aimed to match the measured pressure drop, oil production and effluent salinity profiles.

PowerWindow, a built-in Luminescent Solar Concentrator (LSC), is composed of a window glass with thulium doped coating and a CIGS PV-cell strip attached to one glass edge. LSCs can absorb part of the incoming sunlight and re-direct it to the edges, where PV-cells can produce electricity. Light transport efficiency is then determined by several characteristics of the glass waveguide and thulium as luminescent particles. The main objectives of this work were to find the most relevant characteristics of a LSC affecting its optical efficiency, and to optimize such parameters for a high performance. In the first part of this work, LightTools, a ray-tracing software, was tested to model a LSC based on red-dyes. Simulation results were compared with experimental measurements using a sample of PMMA doped with red-dye (Lumogen F 305). The optical efficiency of the red-dye model was 4.1%, and LSC sample had 4.5% of efficiency (measured in a previous thesis work [Overbeek, 2015]), meaning 0.4% of marginal error. Optical losses were identified and quantified; from them, specular transmission resulted in 25.5% losses, and 0.1% error compared to measurements. In this respect, LightTools was proven to be a useful tool for modelling LSCs and quantify accurately the optical efficiency. With these results, the ray-tracing method proposed was extended for thulium based LSCs. Two thulium LSC models were simulated in LightTools: A glass doped with thulium particles (model 1), and pure glass with thulium coating (model 2, PowerWindow design). From the tested variables, the mean free path (MFP) length, related to the luminophore concentration, is one of the main parameters affecting the optical efficiency and transmission losses. Moreover, the MFP ratio showed high relevance in the optical efficiency since it describes how large is the path length for photons in the emission range compared to blue (absorbed) photons. In both models, it was shown that large MFP ratio (ℛ = 10), high quantum yield (QY= 1), small area (25 cm²), and 5 mm of glass thickness provide optimum results. With these parameters, the optical efficiency of model 1 was 11%, and model 2 about 13%. However, a large scale model 2 of 1 m² had maximum optical efficiency below 1% with light transmission above 80%, and concentration factor of 1. Considering the optical efficiency of this large scale LSC model, and high performance CIGS PV-cells, the energy yield was estimated as only 1.4 kWh per year in the Netherlands. LSC performance might be improved by adding thin film layers in the glass, such as anti-reflection coating and selective filters to allow visible light and reflect NIR photons into the glass.

▼ Conventional stimulation strategies for retinal implants assume evenly distributed, round, grayscale phosphenes, whose intensity can be modulated to reflect different brightness levels in the image that is being presented to the implant recipient. However, it has become increasingly apparent from psychophysical studies that phosphenes can be very complex, varying in size, shape, and sometimes color. In this thesis, it is examined how a user can benefit from a strategy that uses more phosphene properties than just intensity to convey information. In particular, ways to harness the phosphene shape and orientation are investigated in terms of their usefulness to facilitate reading with a retinal implant and increase reading speed. A first focus was the investigation of visual saliency of the perception that retinal implant recipients may experience. The insights obtained through this approach led us to the development of a novel stimulation strategy that used phosphene shapes to add another layer of information to the visual stimulus. To test the novel strategy against a more conventional approach, normally sighted study subjects participated in psychophysical experiments using simulated bionic vision. The first part of this study was based on the assumption that the orientation of phosphenes can deliberately be changed using current steering techniques. Results show that participants perform significantly better in a letter recognition task, even when confronted with large phosphene dropout and phosphene location shift, simulating degraded conditions. In the second part of this study, phosphene shape and direction were modeled based on anatomical retinal ganglion cell data, which allows only for a minimal control over the phosphene appearance. Reading speed was investigated to compare different stimulation strategies operating under this model and to compare them to conventional and fully directional strategies. Results indicate that a fully directional strategy increases reading speed, and that not accounting for axonal stimulation increases the number of incorrectly read words. The directional strategy was found to significantly improve letter discrimination and reading speed in simulations and highlight the importance of accounting for phosphene shapes when designing a stimulation strategy. Our results provide new insights into how visual function performance with current and near-future retinal prostheses can be boosted through sophisticated stimulation strategies. The long term goal of this research focus on phosphene shape is not only to improve the reading performance of retinal implant recipients but also more generally to open new pathways of augmenting their visual perception. This thesis documents the following contributions to knowledge for prosthetic vision: • Visual stimuli lose their natural saliency when represented through phosphenes. In order to steer a patient’s gaze to important image content while maintaining intensity information, we need to make use of several phosphene dimensions.…

▼ With the penetration of PV on the distribution system continually increasing, new advanced simulation methods are necessary to model the potential technical impacts of PV to the equipment and operation of the distribution system. With distributed PV, a timeseries analysis approach is necessary to more fully capture the time-varying nature of solar energy and the interaction with distribution system operations. The objective of the research is to streamline the PV interconnection process by providing more accurate methods that require less time for both the PV interconnection screening criteria and the PV interconnection impact study process. To improve the computational speed of timeseries simulations, an equivalent circuit reduction method is developed to simplify the circuit to a reduced-order model. The reduced circuit is equivalent during timeseries simulations, but it solves in a fraction of the time. The algorithm works with unbalanced multi-phase complex distribution system models, and it is shown to have high accuracy when validated against the full feeder models. An advanced PV hosting capacity simulation tool is developed and used to quantify system impacts for many PV interconnection scenarios, configurations, and locations, which can be generalized to develop improved future interconnection screening criteria. The advanced tools quantify location-specific impacts and the locational hosting capacity of potential PV interconnection locations on the feeder, including PV impact signatures and zones. A set of 50 different real distribution systems is analyzed in detail to demonstrate the range of scenarios and impacts that can occur depending on the feeder characteristics and topology. Specific methods are developed for time-series analysis, faster simulation times, distribution system equivalent circuit reduction, and PV hosting capacity analysis. The advancements presented in this thesis assist in streamlining PV interconnection studies with faster interconnection analysis times and more accurate screening criteria.

▼ Extreme value theory has been used to develop models for describing the distribution of rare events. The extreme value theory based models can be used for asymptotically approximating the behavior of the tail(s) of the distribution function. An important challenge in the application of such extreme value models is the choice of a threshold, beyond which point the asymptotically justified extreme value models can provide good extrapolation. One approach for determining the threshold is to fit the all available data by an extreme value mixture model. This thesis will review most of the existing extreme value mixture models in the literature and implement them in a package for the statistical programming language R to make them more readily useable by practitioners as they are not commonly available in any software. There are many different forms of extreme value mixture models in the literature (e.g. parametric, semi-parametric and non-parametric), which provide an automated approach for estimating the threshold and taking into account the uncertainties with threshold selection. However, it is not clear that how the proportion above the threshold or tail fraction should be treated as there is no consistency in the existing model derivations. This thesis will develop some new models by adaptation of the existing ones in the literature and placing them all within a more generalized framework for taking into account how the tail fraction is defined in the model. Various new models are proposed by extending some of the existing parametric form mixture models to have continuous density at the threshold, which has the advantage of using less model parameters and being more physically plausible. The generalised framework all the mixture models are placed within can be used for demonstrating the importance of the specification of the tail fraction. An R package called evmix has been created to enable these mixture models to be more easily applied and further developed. For every mixture model, the density, distribution, quantile, random number generation, likelihood and fitting function are presented (Bayesian inference via MCMC is also implemented for the non-parametric extreme value mixture models). A simulation study investigates the performance of the various extreme value mixture models under different population distributions with a representative variety of lower and upper tail behaviors. The results show that the kernel density estimator based non-parametric form mixture model is able to provide good tail estimation in general, whilst the parametric and semi-parametric forms mixture models can give a reasonable fit if the distribution below the threshold is correctly specified. Somewhat surprisingly, it is found that including a constraint of continuity at the threshold does not substantially improve the model fit in the upper tail. The hybrid Pareto model performs poorly as it does not include the tail fraction term. The relevant mixture models are applied to insurance and financial applications which…

▼ Multistage tests (MSTs) have received renewed interest in recent years as an effective compromise between fixed-length linear tests and computerized adaptive test. Most MSTs studies scored the assessments based on item response theory (IRT) methods. Many assessments are currently being developed as mixed-format assessments that administer both standalone items and clusters of items associated with a common stimulus called testlets. By the nature of a testlet, a natural dependency occurs between the items within the testlet that violates the local independence of items. Local independence is a fundamental assumption of the IRT models. Using dichotomous IRT methods on a mixed-format testlet-based assessment knowingly violates local independence. By combining the score points within a testlet, researchers have successfully applied polytomous IRT models. However, the use of such models loses information by not using the unique response patterns provided by each item within a testlet. The three-parameter logistic testlet response theory (3PL-TRT) model is a measurement model developed to retain the uniqueness in response patterns of each item, while accounting for the local dependency exhibited by a testlet, or testlet effect. Because few studies have examined mixed-format MSTs administration under the 3PL-TRT model, the dissertation performed a simulation to investigate the administration of a mixed-format testlet based MSTs under the 3PL-TRT model. Simulee responses were generated based on the 3PL-TRT calibrated item parameters from a real large-scale passage based standardized assessment. The manipulated testing conditions considered four panel designs, two test lengths, three routing procedures, and three conditions of local item dependence. The study found functionally no bias across testing conditions. All conditions showed adequate measurement properties, but a few differences did occur between some of the testing conditions. The measurement precision was impacted by panel design, test length and the magnitude of local item dependence. The three-stage MSTs consistently illustrated slightly lower measurement precision than the two-stage MSTs. As expected, the longer test length conditions had better measurement precision than the shorter test length conditions. Conditions with the largest magnitude of local item dependency showed the worst measurement precision. The routing procedure had little impact on the measurement effectiveness.

▼

Une étude inter-annuelle (2000-2003) de la distribution de l’abondance, la biomasse et la composition des espèces phyto-planctoniques couplée aux facteurs environnementaux et le méta zooplancton a été réalisée dans cinq bassins de la saline de Sfax avec un gradient de salinité croissant. Les résultats indiquent une similarité inter-annuelle concernant les caractéristiques physiques de l'eau à savoir la température et la salinité. Les concentrations des éléments nutritifs diminuent avec l'augmentation de la salinité. Nous avons enregistré une nette variation spatiale de la communauté phytoplanctonique. Ainsi, les diatomées dominent dans les premiers bassins A1, A16 et C2-1, suivies par les dino flagellés. Les chlorophycées dominent dans les bassins hypersalésM2 et TS. Les cyanobactéries ont été relativement abondantes dans les bassins M2 et TS. Les abondances et les biomasses phytoplanctoniques les plus élevées ont été enregistrées dans les bassins hyper salés dues à la prolifération de la chlorophycée Dunaliella salina. En raison de la stabilité des facteurs environnementaux,l'étude inter-annuelle de la succession du phytoplancton dans la saline de Sfax a montré des différences légères.Compte tenu du stress salin important, la communauté phytoplanctonique demeure au stade pionnier juvénile.Afin de mieux comprendre les interactions entre les paramètres abiotiques et biotiques, plusieurs analyses statistiques (Test de corrélation Pearson, ANOVA, ACP, Co- inerties….) ont été réalisées. Les relations entre les différents paramètres physiques, chimiques et biologiques au niveau du premier bassin à tendance marine A1 (de salinité 45 p.s.u) semblent être utile pour une modélisation écologique développée pour la saline de Sfax. Ce modèle mis au point a été développé en se basant sur la biomasse de la communauté phytoplanctonique en interaction avec les éléments nutritifs particulièrement l’azote et le phosphore. Une comparaison entre les résultats des simulations et les observations a montré que le modèle écologique a pure produire d’une manière satisfaisante la dynamique saisonnière et inter-annuelle du phytoplancton. Ainsi, les résultats du modèle écologique sont en concordance avec les observations. D’après les simulations, la diminution des concentrations des nutriments, ainsi que l’augmentation du débit d’entrée d’eau dans le bassin A1, entraînent une diminution de la biomasse phytoplanctonique. Cependant, et suite à un réchauffement climatique, une perturbation de la dynamique de la biomasse phytoplanctonique pourrait être observée. De plus, les simulations montrent qu’une année de faible pluviométrie accélère les efflorescences du phytoplancton. Le modèle établi dans la présente étude donne de nouvelles perspectives pour simuler des combinaisons entre les scénarii qui peuvent être dépendants.

Les directives ROHS et WEEE banniront, dans les années qui viennent, le plomb de l’industrie électronique. Seulement, les assemblages électroniques de Schlumberger destinés à des applications hautes températures, tels que les ceux faisant intervenir des composants montés en surface, font intervenir des brasures à forte teneur en plomb. C’est pourquoi, Schlumberger investit énormément afin de trouver de nouvelles brasures sans plomb pour les remplacer. Ce projet, qui s’inscrit dans ce cadre, a pour objectif de prédire la durée de vie d’assemblages utilisant ces nouvelles brasures avec un substrat et des composants en céramique. Cette prédiction se fait en deux étapes. La première est expérimentale. Les assemblages sont soumis à des vieillissements accélérés thermomécaniques et isothermes. En plus de la durée de vie, ces tests apportent des connaissances sur les effets du vieillissement, sur les mécanismes et les zones de défaillances, sur l’interaction de ces brasures avec les finitions du substrat et des composants et enfin sur l’évolution de la microstructure et des phases d’intermétalliques créées lors du vieillissement.La seconde étape est la modélisation de ces assemblages afin de comprendre leur comportement sous sollicitations thermomécaniques. Les simulations aident à comprendre les phénomènes locaux qui apparaissent dans l’assemblage et à extraire des paramètres de fatigue pour diverses conditions thermomécaniques. Enfin, une corrélation entre les résultats de défaillance expérimentaux et la fatigue calculée grâce à la simulation va permettre d’estimer la durée de vie des assemblages pour différentes sollicitations thermomécaniques. Les simulations permettent donc de diminuer le nombre d’essais expérimentaux souvent chers et longs. Seulement, pour faire des simulations fiables, il est nécessaire de connaitre les paramètres mécaniques de tous les matériaux. Pour la brasure, cela veut dire le comportement élastique, plastique et en fluage. Donc, un bénéfice supplémentaire pour Schlumberger est la détermination de ses paramètres pour les nouvelles brasures.

Because of ROHS or WEEE directives, in a close future, lead materials will be banned from electronicindustry. Unfortunately, Schlumberger is using high-lead content solders for surface mount devices forhigh temperature applications. Considering this issue, Schlumberger puts in place high amount of investments to replace these solders by lead-free solders. The topic of the work is to study lead free candidates destined to support Schlumberger high temperature mission profiles. The device under test chosen for this project is a surface mount device composed of a passive component connected to a ceramic substrate by solder joints. The predictive study of reliability of these new assemblies for high temperature applications needs two complementary analyses. The first study is to characterize, experimentally, the life time of surface mount assemblies using these new lead free solders submitted to accelerated thermomechanical and isothermal aging tests. Hence,…

▼ In hydraulic fracturing, a proppant injection schedule practice typically applies a binary proppant mixture (for example: 100 Mesh sand following by 40/70 Mesh sand in well MIP-3H, Marcellus Shale). The former injection agent is finer in size or less resistant to stress, whereas the latter injection agent is coarser in size or more resistant to stress. This practice creates a special region inside the fracture, in which two injected proppant types co-exist and is defined as the mixture zone. This research concentrates on the variability of the mixture zone under impact of different factors, introduces novel semi-analytical modelling approach to better estimate the hydraulic conductivity inside the mixture zone, and further applies this novel approach to prove its efficacy in conductivity estimation and cumulative production prediction. Variability of the mixture zone is studied by an OAT (One at A Time) sensitivity analysis to examine the percentage of the mixture zone’s area over the total propped area under variability of different parameters, including reservoir properties, geo-mechanics, and different design parameters in a proppant injection schedule. The novel semi-analytical model is derived by independent modelling for proppant pack’s permeability and width. Permeability model is an improvement from Carman Kozeny equation, in which Internal Specific Area is re-derived to differ a binary mixture from a single proppant type. Fracture width model is derived from Hertzian contact theory under assumptions of parabola distributed stress, elastic behavior and dual-layer schematic. Trust-region method is applied to determine all coefficients in the permeability model, which complies with a non-linear least square problem. Coefficients in the width model are determined by linear approximation from an in-house fracture width database. Based on satisfied validation results (7.98%-21.82% MRE), trust-region algorithm determines the novel model’s coefficients using lab data of only two Weight Concentration Ratios. The novel model is expanded to predict binary mixture’s conductivity at arbitrary confining stress and Weight Mixing Ratio values, which avoids misleading experimental outcomes. Proppant particle size distribution between two discrete Mesh numbers, deformation complexity between particles (quadratic form) and proppant crush effect are prospective improvements for better modelling validation results. LWAM is proved to overestimate conductivity compared to the novel model. Overestimation degree, which can exceed 70%, is separated into 3 overestimation zones (≤20%, 20-60% and ≥60%) and examined by the comparison matrices. When contrast in density and Mesh size between proppant types in a mixture is clear (for example: mixture 40/70 sand - 20/40 ceramic), overestimation is extreme, and when internal contrast between proppant types in a mixture is reduced (for example: mixture 20/40 sand - 20/40 ceramic), overestimation is dampened.
