description: Assuming the existence of a functional relation among the Standard Model (SM) couplings gauge $α_1$ and quartic $λ$, we determine the mass of the Higgs particle. Similar considerations for the top and bottom Yukawa couplings in the minimal supersymmetric SM lead to the prediction of a narrow window for $\tanβ$, one of the main parameters that determine the light Higgs mass.

Populism and the second crisis of incorporation in Latin America
Creators: name: Boyd, Jaimie Ann
Publisher: name: University of British Columbia

description: Beginning with the election of Hugo Chávez in 1998, populist leaders have come to power in many Latin American countries. I argue that this recent wave of populism results from demands for incorporation made by marginalized, unorganized groups. Their demands are a reflection of acute inequality and, when aggregated, lead to crisis. Populist movements, parties, and leaders tend to emerge during such crises because they are able to take advantage of the presence of groups that become de-incorporated or that were never incorporated and mobilize them within existing state structures. This is a distinctive pattern in highly unequal societies where a full set of rights and freedoms has not been universalized. I illustrate the usefulness of my approach by applying it to the rise of Chávez in Venezuela. I conclude that, where populism enables meaningful incorporation of marginalized groups, it may ultimately provide an improved basis for long-term democracy in Latin America.

description: Menaquinone (MK) serves as an essential membranous redox mediator in various electron transport chains of aerobic and anaerobic respiration. In addition, the composition of the quinone/quinol pool has been widely used as a biomarker in microbial taxonomy. The HemN‐like class C radical SAM methyltransferases (RSMTs) MqnK, MenK and MenK2 have recently been shown to facilitate specific menaquinone methylation reactions at position C‐8 (MqnK/MenK) or C‐7 (MenK2) to synthesize 8‐methylmenaquinone, 7‐methylmenaquinone and 7,8‐dimethylmenaquinone. However, the vast majority of protein sequences from the MqnK/MenK/MenK2 family belong to organisms, whose capacity to produce methylated menaquinones has not been investigated biochemically. Here, representative putative menK and menK2 genes from Collinsella tanakaei and Ferrimonas marina were individually expressed in Escherichia coli (wild‐type or ubiE deletion mutant) and the corresponding cells were found to produce methylated derivatives of the endogenous MK and 2‐demethylmenaquinone. Cluster and phylogenetic analyses of 828 (methyl)menaquinone methyltransferase sequences revealed signature motifs that allowed to discriminate enzymes of the MqnK/MenK/MenK2 family from other radical SAM enzymes and to identify C‐7‐specific menaquinone methyltransferases of the MenK2 subfamily. This study will help to predict the methylation status of the quinone/quinol pool of a microbial species (or even a microbial community) from its (meta)genome and contribute to the future design of microbial quinone/quinol pools in a Synthetic Biology approach.

description: Neuroblastoma is the most common extracranial solid tumour in infants and long-term survival for high-risk patients is below 50%. Generating antitumour immune responses have indicated potential. We hypothesized that sunitinib would modulate immune responses to improve oncolytic virus (VSVΔM51) productivity in the tumour and enhance the activity of antitumour immunity activated by VSVΔM51. Using an immunocompetent mouse model of neuroblastoma (neuro-2a), we found that VSVΔM51/sunitinib combination therapy elicited superior tumour regression and durable cure rates compared to either agent alone. We tested sunitinib’s ability to enhance infection in neuro-2a tumours, however, we found that infection with or without sunitinib was identical. We further tested whether sunitinib augmented antitumour immunity generated by VSVΔM51. We found that CD8+ T-cell depletion abolished the survival advantage elicited by VSVΔM51/sunitinib, indicating that sunitinib promoted adaptive immune responses. Collectively our results show that sunitinib improves VSVΔM51 therapy in neuro-2A tumours and is dependent on CD8+ T-cells.

description: A post-Markovian master equation has been recently proposed as a tool to describe the evolution of a system coupled to a memory-keeping environment [A. Shabani and D. A. Lidar, Phys. Rev. A 71, 020101 (R) (2005)]. For a single qubit affected by appropriately chosen environmental conditions, the corresponding dynamics is always legitimate and physical. Here we extend such situation to the case of two qubits, only one of which experiences the environmental effects. We show how, despite the innocence of such an extension, the introduction of the second qubit should be done cum grano salis to avoid consequences such as the breaking of the positivity of the associated dynamical map. This hints at the necessity of using care when adopting phenomenologically derived models for evolutions occurring outside the Markovian framework.

description: Eradication of code smells is often pointed out as a way to improve readability, extensibility and design in existing software. However, code smell detection in large systems remains time consuming and error-prone, partly due to the inherent subjectivity of the detection processes presently available. In view of mitigating the subjectivity problem, this paper presents a tool that automates a technique for the detection and assessment of code smells in Java source code, developed as an Eclipse plug-in. The technique is based upon a Binary Logistic Regression model and calibrated by expert's knowledge. A short overview of the technique is provided and the tool is described.

subject: Airport classification

description: Service quality in airport terminals is considered very important to multiple stake holders including passengers, airlines, airport operator, concessionaires and local community. A critical need for the airport industry is the availability of techniques for evaluating the service quality provided to passengers. Defining overall service quality standards is important in terms of designing, managing and benchmarking the service quality of a passenger terminal. Currently there is no technique capable of defining overall service quality standards for airport terminals using objectively defined service performance criteria. Objective measurement is defined as service performance measurements determined using quantitative measurements that cannot be subjected to value criticism. This thesis presents a comprehensive technique for determining standards of overall service quality at airport passenger terminals using objectively measured service performance criteria. Criteria for defining overall service quality standards is determined based on the value of relative importance of different service attributes at the passenger terminal. Passenger opinion was used to determine the value of attribute relative importance. A stated preference survey format was used to collect data from the passengers in order to calculate values of attribute relative importance. Advantages achieved with the technique are its versatility of recruiting respondents with a wider representation of the target population and the ability to cover a wider range of service attributes within the survey. Respondents were recruited at the main terminal of The Calgary International airport and online. Discrete choice modelling and generalised ordinal regression analysis were used as main analysis models. Finally a comprehensive evaluation scheme is developed as a tool to measure the overall service quality of a given airport terminal relative to the overall service quality standards defined by the study. The main contribution of the research is the development of a methodology to establish overall service quality standards and the evaluation scheme for overall service quality measurement at airport terminals. Future work is recommended to extend this methodology and develop a comprehensive industry application with industry wide consensus.
Regulating p21 Expression to Increase Chondrogenic Potential in Human Mesenchymal Progenitor Cells

description: Cartilage does not regenerate in humans, and therefore cartilage degeneration is a problem that affects a significant percentage of the population, including those with diseases such as Osteoarthritis (OA). The p21 knockout (p21-/-) mouse contains the only known single mutation in mammals that can induce a cartilage regenerative phenotype. Work in this thesis aims to identify p21 expression inhibitors for use in humans and to characterize their effects on human synovial mesenchymal progenitor cells (MPCs) during culture and chondrogenesis. I have identified one putative p21 expression inhibitor (acting through HSP90), that induces human synovial MPCs to display phenotypic properties similar to fibroblasts from p21-/- mice. Additionally, this inhibitor promotes cartilage formation in a mouse cartilage injury model. These results indicate that p21 inhibition through HSP90 may be a potential pharmaceutical target for stimulating chondrogenic regeneration for the treatment of cartilage defects or in cartilage degenerating diseases such as OA.

description: Diabetes and Ischemic Preconditioning (IPC) have been shown in literature to have similar metabolic and microscopic effects on intercellular coupling, conduction reserve, and the response to ischemia-reperfusion in ventricular tissue. Both diabetes and IPC cause reduced intercellular coupling; reduced conduction reserve; and provide cardio-protection to ischemia/reperfusion. To determine the whole heart similarities between IPC and diabetes both electrocardiograph (ECG) and optical mapping data was evaluated. Diabetes displayed different time dependent responses to ischemia/reperfusion from IPC and healthy animals; diabetic animals slow heart rate significantly compared to IPC and control animals during ischemia, while IPC slows conduction velocity. During pacing, IPC and diabetic animals showed similar slowing of conduction velocity though only diabetic animals showed significant slowing in response to reduced cellular excitability. This work suggests IPC and diabetes do not use the same mechanisms to provide cardio-protective effects.

description: Recent work suggests brain signal variability tracks maturational changes in information processing capacity. Evidence also suggests variability changes with task demands. Here, we investigate whether there is an interaction between age and task related changes in brain signal variability measured with electroencephalography (EEG). We looked at brain signal variability changes during different epochs within trial (i.e., before to after stimulus onset, and after response) and with task difficulty, in children (age 8-14) and adults (age 18-33). In the epochs within trial analysis, we found similar changes pre- to post-stimulus onset in both age groups, but a later return to baseline in children then adults. In the task difficulty analysis, variability changed with difficulty conditions only in children. Our data suggest that age-related differences in variability changes with task reflect differences in the cognitive processing performed by children and adults during task performance.
Phenotypic and Genotypic Evaluation of the Prairie Epidemic Strain (PES): A Transmissible Strain of Pseudomonas aeruginosa Found in Patients With Cystic Fibrosis

description: Epidemic strains of Pseudomonas aeruginosa have been found worldwide in cystic fibrosis (CF) patients. The recently described Prairie Epidemic Strain (PES) is found in patients attending several Western Canadian CF clinics. In this study, we characterized PES genotypically and phenotypically. The clonality of PES was first described using pulse-field gel electrophoresis. Here we confirm that observation with multi-locus sequence typing, where PES isolates from unrelated patients were identified to have ST192 consistently. As epidemic strains are associated with worse clinical outcomes, we assessed the pathogenic potential of PES relative to other epidemic strains (OES) and local non-epidemic isolates. We conducted a comparative analysis using fourteen phenotypic traits, including virulence factor production, biofilm formation, planktonic growth, mucoidy, and antibiotic susceptibility to characterize 118 P. aeruginosa isolates. The analysis indicated that the OES and local non-epidemic isolates had distinct phenotypic traits, but PES shared characteristics with both of the other groups. Strain replacement was identified amongst five patients whereby local non-epidemic isolates were displaced by PES. These PES isolates produced lower levels of proteases and elastases but were more resistant to antibiotics compared to the displaced non-epidemic isolates suggesting that virulence is not the sole factor involved in displacing previous colonizers. Simulations of super-infections using the Drosophila melanogaster model demonstrated that a PES isolate was able to attenuate virulence when co-infected with a local non-epidemic isolate, which suggested that bacterial competition was occurring with PES having a competitive advantage. This study aimed to elucidate potential mechanisms used in strain replacement and investigated the role of the type 6 secretion system (T6SS) by using a cell-dependent killing assay. These assays indicated that the T6SS is not likely the mechanism that the PES were using to outcompete the local non-epidemic isolates. This comparative analysis is the first to be done on a large scale between groups of epidemic and non-epidemic CF P. aeruginosa isolates. This work is significant because it aimed to better understand epidemic P. aeruginosa infections in the CF population.

description: We report on very high energy (E > 100 GeV) gamma-ray observations of V407 Cygni, a symbiotic binary that underwent a nova outburst producing 0.1-10 GeV gamma rays during 2010 March 10-26. Observations were made with the Very Energetic Radiation Imaging Telescope Array System during 2010 March 19-26 at relatively large zenith angles, due to the position of V407 Cyg. An improved reconstruction technique for large zenith angle observations is presented and used to analyze the data. We do not detect V407 Cygni and place a differential upper limit on the flux at 1.6 TeV of 2.3 \times 10^(-12) erg cm^(-2) s^(-1) (at the 95% confidence level). When considered jointly with data from Fermi-LAT, this result places limits on the acceleration of very high energy particles in the nova.

description: Gliomas are the most common primary adult brain tumors. Despite current treatment, including surgery radio- and chemotherapy, these tumors continue to progress and recur with a more aggressive and resistant phenotype. Recurrence is believed to be, in no small part, due to the presence within the tumors of Brain Tumor Initiating Cells (BTICs). These cells have stem-like properties, are resistant to therapeutic effort and demonstrate enhanced tumorigenic potential. The key molecular alterations sustaining growth and therapeutic resistance in gliomas are now well described. However, targeted therapies have so far failed to make significant impact in the clinic, perhaps due to the heterogeneity and rapid evolution characteristic of these tumors. A better understanding of the players driving recurrence and the molecular pathways to initiation and progression in gliomas is hence essential to developing novel therapeutic strategies and improve clinical outcome. Isocitrate dehydrogenase 1 or 2 (IDH1/2) mutation is found in grade II-III astrocytomas, oligodendrogliomas and in secondary glioblastomas (GBMs), but is completely absent from primary GBMs, thus reflecting a different origin and evolution. In the first section of this thesis, we study the IDH1/2 mutation in glioma and its contradictory roles during tumor initiation and progression. More specifically, we show that the IDH1/2 mutation is directly involved in downregulating glycolytic genes such as LDHA. We also report the selection of large chr2 deletions resulting in the loss of either the IDH1 wild-type or mutant allele. Although essential during initiation, we argue that the IDH1/2 mutation may be a limiting factor of tumor progression at later stages of tumorigenesis. Often considered a different disease, primary GBMs are the most aggressive and lethal primary brain tumors. In the second section of this thesis, we focus on these tumors through the study of primary GBM-derived BTICs. We report the existence of distinct precursor states (stem-like and progenitor-like) in BTICs predictive of survival and associated with GBM subtypes. Further, we highlight a STAT3-driven EMT-like process in progenitor-like BTICs, which may drive the progression towards more aggressive and resistant recurrent GBM.

Exploring Novel Strategies for Universal Detection in Chromatography
Creators: name: Scott, Andrea Ferelyth
Publisher: name: Graduate Studies
Year: 2016
Subjects: Chemistry--Analytical

description: This thesis presents novel strategies for the universal detection of polar analytes in chromatography. This included the further development of a universal detector that is compatible with organic solvents, as well as exploring separation techniques that are compatible with the universal Flame Ionization Detector (FID). For instance, the universal response of the Acoustic Flame Detector (AFD) was comprehensively compared to the FID, where a very close linear correlation (r2 of 0.9103) was found between them. A few minor exceptions were also observed, where the most notable differences occurred for organometallic compounds. Overall, results indicate that the AFD provides a uniform response toward most hydrocarbons that is qualitatively very similar to that of an FID. Interestingly, a novel response mode for alkali metals was also observed in a Subcritical Water Chromatography operating regime. Optimal hydrogen flame gas flow rates were found near 40 mL/min for hydrocarbon response and 80 mL/min for alkali response. KCl, NaCl, LiCl and ethanol each displayed a linear FID response with respective sensitivities of 7500, 980, 130 and 1 mV/µg of analyte. This was subsequently demonstrated to greatly alter the FID response of organic salts. Accordingly, their presence in analytical samples or mobile phases must therefore be accounted for when using this detector. Finally, a novel method of separating polar analytes in Supercritical Fluid Chromatography through dynamically controlling analyte retention by tuning the pH of a water stationary phase is presented. The method utilizes a change in mobile phase from N2 to CO2 to effectively reduce stationary phase pH and control the elution of organic acids from the column. This effect is also observed to be reasonably independent of column length and time. For example in the latter case, at 80oC, a hexanoic acid standard analyte can be readily eluted on demand from a 10 m column by switching to CO2 at any point over a run time of about 1 hour. The N2/CO2 switching system is used to analyze organic acids present in a variety of different samples and it is found that they can be eluted on demand with high selectivity over other matrix components.

description: We investigate the star cluster population in the outer parts of the starburst galaxy NGC 5253 using archive images taken with the Hubble Space Telescope's Advanced Camera for Surveys. Based on the F415W, F555W, and F814W photometry ages and masses are estimated for bona-fide star cluster candidates. We find three potentially massive ($\ge 10 \time 10^5$ \Msun) star clusters at ages of order of 1-2 Gyr, implying, if confirmed, a high global star formation rate in NGC 5253 during that epoch. This result underlines earlier findings that the current star burst is just one episode in an very active dwarf galaxy.

description: Although researchers have spent decades characterizing typical brain and motor development, limited research has bridged these two fields by examining the associations between brain structure and motor behavior. The current study uses both diffusion and T1-weighted magnetic resonance imaging (MRI) to investigate the relationships between brain microstructure, macrostructure, and motor abilities in 68 typically developing preschool children, aged 3 to 5 years. The Movement Assessment Battery for Children-2nd edition (MABC-II) was used to assess motor functioning in children. Associations between MABC-II total test standard scores and white matter anisotropy and diffusivity in callosal motor fibers (CC) and corticospinal tracts (CST) were examined. Associations of MABC-II scores and whole brain structural properties (i.e., cortical thickness and volume) in canonical motor regions were also examined. Motor scores were found to correlate with measures of anisotropy and diffusivity in CC motor fibers. No associations were found between motor performance and measures of anisotropy or diffusivity in either the left or right CST. Finally, no associations were observed between cortical and subcortical macrostructure and motor abilities in preschool-aged children. These findings suggest a relationship between callosal fiber white matter structure and motor performance in typically developing preschool-aged children, and that structural variation in callosal motor fibers but not corticospinal tracts, may partially account for the natural variability in motor performance seen across typically developing preschool children. Clarifying brain-motor behavior relationships in typically developing children could help to inform future studies on the etiology and physiology of developmental motor impairments in pediatric populations.

description: This study examined the fit of a continuum model of uncontrolled eating as extended to measures of food and eating addiction, and investigated associations of these constructs with clinical impairment. Participants were 544 adults recruited through an online crowdsourcing tool, and 358 students. We tested the fit of structural equation models depicting a continuum of uncontrolled eating, and examined relationships among self-report measures of food and eating addiction, emotional eating, power of food, binge eating, and clinical impairment. Results supported the convergent validity of food and eating addiction measures with measures of theoretically similar forms of eating pathology. Food addiction demonstrated incremental validity in explaining clinical impairment above the general uncontrolled eating factor in both samples, and was equivalently associated with all types of impairment. Eating addiction was more strongly associated with personal (i.e., emotional) impairment, but did not account for variance in impairment beyond the general uncontrolled eating factor.

Material examined (N=86). 2m, 9f, 12/VI/2004, St. 0 1 (MZUESC #651); 7m, 10f, 24/III/2005, St. 0 4 (MZUESC #730); 14m, 5f, 1ni, 25/III/2005, St. 0 5 (MZUESC #731); 2m, 1f, 1ni, 07/VIII/2005, St. 0 5 (MZUESC #743).
Distribution. Western Atlantic – from North Carolina to western Gulf of Mexico, Antilles (West Indies to Aruba), and Brazil (Rocas Atoll, oceanic banks off Ceará, and from Amapá to Alagoas, Espírito Santo, and São Paulo) (Williams 1984; Ramos-Porto & Coelho 1998; Calado & Sousa 2003).
Ecological notes. In sand and gravel bottoms, seagrass, tidepools, and in sponges. From shallow waters to 105 m (Ramos-Porto & Coelho 1990; Ramos-Porto & Coelho 1998; Calado & Sousa 2003).
Previous records in Bahia. None.
Remarks. This species was recently transferred from the genus Periclimenes Costa, 1844 to Kemponia erected by Bruce (2004). Although K. americana is known from several states in northern and northeastern Brazil, cited as P. americanus (Coelho & Ramos 1972; Ramos-Porto & Coelho 1990; Ramos-Porto & Coelho 1998; Calado & Sousa 2003), we found no literature records between the states of Alagoas and Espírito Santo. Hence, we record the species from Bahia for the first time.

description: The beaming effect (aka Doppler boosting) induces a variation in the observed flux of a luminous object, following its observed radial velocity variation. We describe a photometric signal induced by the beaming effect during eclipse of binary systems, where the stellar components are late type Sun-like stars. The shape of this signal is sensitive to the angle between the eclipsed star's spin axis and the orbital angular momentum axis, thereby allowing its measurement. We show that during eclipse there are in fact two effects, superimposed on the known eclipse light curve. One effect is produced by the rotation of the eclipsed star, and is the photometric analog of the spectroscopic Rossiter-McLaughlin effect, thereby it contains information about the sky-projected spin-orbit angle. The other effect is produced by the varying weighted difference, during eclipse, between the beaming signals of the two stars. We give approximated analytic expressions for the amplitudes of the two effects, and present a numerical simulation where we show the light curves for the two effects for various orbital orientations, for a low mass ratio stellar eclipsing binary system. We show that although the overall signal is small, it can be detected in the primary eclipse when using Kepler Long Cadence data of bright systems accumulated over the mission lifetime.

Modeling the 8-queens problem and Sudoku using an algorithm based on projections onto nonconvex sets
Creators: name: Schaad, Jason
Publisher: name: University of British Columbia
Year: 2010

description: We begin with some basic definitions and concepts from convex analysis and projection onto convex sets (POCS). We next introduce various algorithms for converging to the intersection of convex sets and review various results (Elser’s Difference Map is equivalent to the Douglas-Rachford and Fienup’s Hybrid Input-Output algorithms which are both equivalent to the Hybrid Projection-Reflection algorithm). Our main contribution is two-fold. First, we show how to model the 8-queens problem and following Elser, we model Sudoku as well. In both cases we use several very nonconvex sets and while the theory for convex sets does not apply, so far the algorithm finds a solution. Second, we show that the operator governing the Douglas-Rachford iteration need not be a proximal map even when the two involved resolvents are; this refines an observation of Eckstein.

description: SNO+ will search for neutrinoless double beta decay by loading 780 tonnes of linear alkylbenzene liquid scintillator with O(tonne) of neodymium. Using natural Nd at 0.1% loading will provide 43.7 kg of 150Nd given its 5.6% abundance and allow the experiment to reach a sensitivity to the effective neutrino mass of 100-200 meV at 90% C.L in a 3 year run. The SNO+ detector has ultra low backgrounds with 7000 tonnes of water shielding and self-shielding of the scintillator. Distillation and several other purification techniques will be used with the aim of achieving Borexino levels of backgrounds. The experiment is fully funded and data taking with light-water will commence in 2012 with scintillator data following in 2013.

description: We present the discovery of substellar-mass companions to three giant stars by the ongoing Penn State-Toruń Planet Search (PTPS) conducted with the 9.2 m Hobby-Eberly Telescope. The most massive of the three stars, K2-giant HD 240237, has a 5.3 MJ minimum mass companion orbiting the star at a 746-day period. The K0-giant BD +48 738 is orbited by a > 0.91 MJ planet which has a period of 393 days and shows a non-linear, long-term radial velocity trend that indicates a presence of another, more distant companion, which may have a substellar mass or be a low-mass star. The K2-giant HD 96127, has a > 4.0 MJ mass companion in a 647-day orbit around the star. The two K2-giants exhibit a significant RV noise that complicates the detection of low-amplitude, periodic variations in the data. If the noise component of the observed RV variations is due to solar-type oscillations, we show, using all the published data for the substellar companions to giants, that its amplitude is anti-correlated with stellar metallicity.

description: We map the full extent of a rich massive young cluster in the Cep OB3b association with the IRAC and MIPS instruments aboard the {\it Spitzer} Space Telescope and the ACIS instrument aboard the $\it{Chandra}$ X-Ray Observatory. At 700 pc, it is revealed to be the second nearest large ($>1000$ member), young ($< 5$ Myr) cluster known. In contrast to the nearest large cluster, the Orion Nebula Cluster, Cep OB3b is only lightly obscured and is mostly located in a large cavity carved out of the surrounding molecular cloud. Our infrared and X-ray datasets, as well as visible photometry from the literature, are used to take a census of the young stars in Cep OB3b. We find that the young stars within the cluster are concentrated in two sub-clusters; an eastern sub-cluster, near the Cep B molecular clump, and a western sub-cluster, near the Cep F molecular clump. Using our census of young stars, we examine the fraction of young stars with infrared excesses indicative of circumstellar disks. We create a map of the disk fraction throughout the cluster and find that it is spatially variable. Due to these spatial variations, the two sub-clusters exhibit substantially different average disk fractions from each other: $32% \pm 4%$ and $50% \pm 6%$. We discuss whether the discrepant disk fractions are due to the photodestruction of disks by the high mass members of the cluster or whether they result from differences in the ages of the sub-clusters. We conclude that the discrepant disk fractions are most likely due to differences in the ages.

description: Data plays an important role in our daily life. Thus, data collection, storage, maintenance and processing continue to attract considerable attention. Data may exist in various formats, ranging from unstructured to structured as the two extremes. Traditionally, researchers and practitioners cooperated and developed various data models which form the main foundation for existing database management systems. The relational data model is still dominating despite the rapid development in the techniques used for data collection, storage and processing. Further, a relational database management system supports a structured query language (SQL) for data processing, and it is not possible to access and retrieve data from a relational database without knowing how to use SQL. However, the wide usage of relational databases motivated researchers to develop more user friendly interfaces which would allow a larger population of users to access relational databases. Such interfaces range from visual to natural language based. This thesis contributes a question driven query model which falls under the natural language based category. The target is to make databases reachable by a larger population, especially after the Internet increased database availability. The proposed model supports fuzziness where every user is given the freedom to de ne his/her own understanding of fuzzy terms. The developed system absorbs the fuzzy understanding of each user to utilize it while deciding on the result to be communicated back as answer to the raised question. Data mining techniques are employed to guide users in de ning their fuzzy understanding. The developed model is intended to help users to retrieve the data they want from a relational database without expecting them to know SQL. In the current version only questions written in English are allowed. The system handles di erent types of questions, such as (1) simple questions, (2) complex questions with inner joins and where conditions, (3) questions that involves the usage of aggregate functions (e.g., min, max, etc.), and (4) questions with fuzzy terms. The reported test results demonstrate the e ectiveness of the developed system in handling various types of questions raised by a heterogeneous set of users ranging from professionals to naive.
Understanding Uncertainties Using Performance Predictive Models for Smart Waterflooding

description: Smart waterflooding involves an injection of water that contains an optimum concentration of electrolytes that are tailored to the rock-fluid characteristics of the target reservoir. The objective of this study is to identify uncertainties that could affect the performance of a smart waterflooding process and to determine how such risks can be diminished. To this end, the impact of parameters that contribute to uncertainties was investigated using a modeling approach. The key parameters identified as critical variables in the core-scale to field-scale analyses are the following: permeability, porosity, viscosity ratio, temperature, clay content, carbonate content, sodium, calcium, chlorine, calcite, dolomite, feldspar, pH, initial water saturation, heterogeneities, inter-well spacing, and production/injection pressure. These parameters have a significant effect on smart waterflooding performance. Many of these variables—temperature, mineralogy, aqueous composition, and pH—directly influence smart waterflooding process. However, the rest of the variables affect both the conventional and smart waterflooding processes. Furthermore, there is a significant binary interaction between variables. Each parameter effect was qualified and quantified by the normalized parameter method. Empirical predictive models for, (i) residual saturation, (ii) end-point water-relative permeability, and (iii) oil recovery were developed from a multivariable regression model with R-square prediction greater than 78%.
