description: Organizations own data sources that contain millions, billions or even trillions of rows and these data are usually highly dimensional in nature. Typically, these raw repositories are comprised of numerous independent data sources that are too big to be copied or joined, with the consequence that aggregations become highly problematic. Data cubes play an essential role in facilitating fast Online Analytical Processing (OLAP) in many multi-dimensional data warehouses. Current data cube computation techniques have had some success in addressing the above-mentioned aggregation problem. However, the combined problem of reducing data cube size for very large and highly dimensional databases, while guaranteeing fast query response times, has received less attention. Another issue is that most OLAP tools often causes users to be lost in the ocean of data while performing data analysis. Often, most users are interested in only a subset of the data. For example, consider in such a scenario, a business manager who wants to answer the crucial location-related business question. "Why are my sales declining at location X"? This manager wants fast, unambiguous location-aware answers to his queries. He requires access to only the relevant ltered information, as found from the attributes that are directly correlated with his current needs. Therefore, it is important to determine and to extract, only that small data subset that is highly relevant from a particular user's location and perspective. In this thesis, we present the Personalized Smart Cube approach to address the abovementioned scenario. Our approach consists of two main parts. Firstly, we combine vertical partitioning, partial materialization and dynamic computation to drastically reduce the size of the computed data cube while guaranteeing fast query response times. Secondly, our personalization algorithm dynamically monitors user query pattern and creates a personalized data cube for each user. This ensures that users utilize only that small subset of data that is most relevant to them. Our experimental evaluation of our Personalized Smart Cube approach showed that our work compared favorably with other state-of-the-art methods. We evaluated our work focusing on three main criteria, namely the storage space used, query response time and the cost savings ratio of using a personalized cube. The results showed that our algorithm materializes a relatively smaller number of views than other techniques and it also compared favourable in terms of query response time. Further, our personalization algorithm is superior to the state-of-the art Virtual Cube algorithm, when evaluated in terms of the number of user queries that were successfully answered when using a personalized cube, instead of the base cube.

description: In 1946 the magazine "La Fiera letteraria" hosted two important essays dedicated to psychoanalysis and poetry. The first, written by Benedetto Croce, was a few pages letter, which substantially rejected the claims of novelty and originality of "Freudianism", especially in philosophy. The other was a much more detailed and articulate response by poet Umberto Saba, which instead appreciated the psychoanalysis (and not only as therapy).We decided to republish these two texts by preceding them with two other brieg contributions by Benedetto Croce on psychoanalysis. The first is a review of the French translation of Freud's text on dream of 1903, and the second is a critical contemptuous of the "so-called stylistic criticism", that is put in relation with the Montessori method and to psychoanalysis
description: Nel 1946 “La Fiera letteraria” ospitò due importanti interventi dedicati a psicoanalisi e poesia. Il primo, per mano nientemeno che di Benedetto Croce, era una lettera di poche pagine, di sostanziale chiusura nei confronti delle pretese novità e originalità del “freudismo” soprattutto in ambito filosofico. Il secondo era la risposta, molto più dettagliata e articolata di un poeta come Umberto Saba, che invece alla psicoanalisi (e non solo come terapia) credeva e teneva molto. Riproponiamo qui questi due testi, preceduti da altri due brevi interventi di Croce sulla psicoanalisi: il primo è una recensione alla traduzione francese del testo di Freud sul sogno del 1903; il secondo è una critica sprezzante nei confronti della “cosiddetta critica stilistica”, che viene messa in relazione al metodo Montessori e appunto alla psicoanalisi.

description: This paper proposes a new theoretical model in which pure energy self-organizes through geometric resonance into matter, simultaneously driving cosmic expansion. This theory, rooted in the principles of spiral motion, vibration, cymatics, and higher-dimensional geometry, aims to bridge the gap between general relativity and quantum mechanics by introducing a dual-spiral framework for matter formation and the propagation of dark energy. Central to this model is the role of the tesseract (4D hypercube) as the energetic container through which energy stabilizes into form. This paper explores the idea that dark matter is the structural geometry that holds spiraling energy in place. In contrast, dark energy is the outward spiral pressure, the expansive force released as a byproduct of the formation of matter.

description: Immigrant entrepreneurship’s social and political dimensions remain largely overlooked in leisure studies scholarship. In Canada, investigations of immigrant entrepreneurship have, with very few exceptions, been limited to the economic sphere. Through the theoretical work of Michel Foucault, critical discourse analysis, semi-structured interviews, and participant observation, in this dissertation I expose and explore the intersections between multicultural citizenship discourses and leisure-oriented non-European immigrant entrepreneurship in the Windsor-Essex region of southwestern Ontario. Written in the publishable paper format, this dissertation is comprised of three stand-alone papers: paper one illustrates how citizenship discourses produced and exercised through Canada’s Multiculturalism Act (Canada, 1988) simultaneously inhibit and enable immigrants’ leisure pursuits; paper two demonstrates how non-European immigrants use leisure-based entrepreneurship to affirm and resist constraints exercised through multicultural citizenship discourses; finally, paper three demonstrates how non-European immigrants use leisure-based entrepreneurship to expand their possibilities for recognition and equal rights in the social, cultural, and political spheres of Canadian society. My findings indicate that leisure-based entrepreneurship is an important site for immigrant minorities’ civic engagement. It is a space and a medium to express and sustain distinctive cultural traditions and practices. Further, it serves as a strategy for immigrant minorities to break down barriers and create opportunities for themselves and others to participate in and experience a wide range of leisure traditions and practices. In short, through this dissertation I show that leisure-based entrepreneurship is a technique employed by immigrant minorities to assert their membership in Canadian society and to lay claims to full and equal citizenship rights. Leisure-oriented immigrant entrepreneurship, I argue, is an important site for active citizenship.

description: Maternal smoking during pregnancy has often been associated with numerous adverse outcomes for the offspring. However, its long-term effects are not well established. Given the high prevalence of maternal smoking during pregnancy, an understanding of these effects is essential. Therefore, the aim of the present dissertation was to shed light on the long-term neurophysiological effects of prenatal nicotine exposure on three different executive functioning processes by assessing participants in young adulthood, using functional magnetic resonance imaging (fMRI). Participants imaged were members of the Ottawa Prenatal Prospective Study, a longitudinal study that collected a unique body of information on participants from infancy to young adulthood, which allowed for the measurement of an unprecedented number of potentially confounding drug exposure variables. The dissertation consists of three separate original manuscripts. In manuscript 1, participants completed a response inhibition task, in manuscript 2 participants completed a verbal working memory task and in manuscript 3 participants completed a visuospatial working memory task. Taken together, results from all three manuscripts showed that prenatal nicotine exposure leads to altered neural functioning during executive functioning processing that continues into young adulthood. These significant results highlight the need for education about the repercussions of women smoking during pregnancy.

description: Nanocelluloses, both cellulose nanofibrils and cellulose nanocrystals, are gaining research traction due to their viability as key components in commercial applications and industrial processes. Significant efforts have been made to understand both the potential of assembling nanocelluloses, and the limits and prospectives of the resulting structures. This Review focuses on bottom-up techniques used to prepare nanocellulose-only structures, and details the intermolecular and surface forces driving their assembly. Additionally, the interactions that contribute to their structural integrity are discussed along with alternate pathways and suggestions for improved properties. Six categories of nanocellulose structures are presented: (1) powders, beads, and droplets; (2) capsules; (3) continuous fibres; (4) films; (5) hydrogels; and (6) aerogels and dried foams. Although research on nanocellulose assembly often focuses on fundamental science, this Review also provides insight on the potential utilization of such structures in a wide array of applications.
Marketing students' perceptions of online recorded lectures

description: Students enrolled in two on-campus marketing units were surveyed about their claimed attendance at face-to-face lectures and tutorials and their access to online recordings of the lectures. Only around 30% of students claim they attend all lectures, with tutorial attendance higher for both student cohorts. Most students claim they listen to at least eight (out of twelve) of the online recorded lectures, although there does not appear to be a correlation between accessing these recordings and actual attendance - we had expected that nonattendees would claim the highest rates of listening to the recordings. Students appear to access the recordings more for revision or translation purposes, rather than to catch up lectures they have missed.
High-order well-balanced methods for systems of balance laws: a control-based approach

description: In some previous works, two of the authors have introduced a strategy to develop high-order numerical methods for systems of balance laws that preserve all the stationary solutions of the system. The key ingredient of these methods is a well-balanced reconstruction operator. A strategy has been also introduced to modify any standard reconstruction operator like MUSCL, ENO, CWENO, etc. in order to be well-balanced. This strategy involves a non-linear problem at every cell at every time step that consists in finding the stationary solution whose average is the given cell value. So far this strategy has been only applied to systems whose stationary solution are known either in explicit or implicit form. The goal of this paper is to present a general implementation of this technique that can be applied to any system of balance laws. To do this, the nonlinear problems to be solved in the reconstruction procedure are interpreted as control problems: they consist in finding a solution of an ODE system whose average at the computation interval is given. These problems are written in functional form and the gradient of the functional is computed on the basis of the adjoint problem. Newton's method is applied then to solve the problems. Special care is put to analyze the effects of computing the averages and the source terms using quadrature formulas. To test their efficiency and well-balancedness, the methods are applied to a number of systems of balance laws, ranging from easy academic systems consisting of Burgers equation with some nonlinear source terms to the shallow water equations or Euler equations of gas dynamics with gravity effects.

description: This thesis analyzes representations of female resistors of the Mojahedin-e Khalq or People’s Mojahedin Organization of Iran within contemporary schools of academia and western/Iranian medias. Theoretically informed by critical discourse analysis and feminist thought this project identifies common stereotypes attributed to women involved in proscribed violence. Furthermore, this dissertation tests for the presence of normative and ‘gendered’ portrayals of female resistors in popular discourse, evaluates their sufficiency, and presents a more accurate portrait based on interviews and a close analysis of the organization’s history and policies. In other words, it critically examines how female resistors of the MEK/PMOI are captured by the common portrait and through the study of experiential authorship and interviews demonstrates the need to re-evaluate the narratives used to misrepresent an organization and its members who have radicalized notions of gender equality and its relationship to revolution and democratization. Cette thèse analyse les représentations des femmes dans la résistance des Moudjahiddines-e khalq ou l’Organisation des moudjahiddines du peuple iranien dans les écoles contemporaines du monde universitaire et des médias occidentaux / iranienne. Théoriquement informé par l'analyse critique du discours et par la pensée féministe, ce projet identifie les stéréotypes courants attribués aux femmes impliqués dans la violence proscrite. En outre, cette thèse cherche la présence de représentations normatives et «genrées» des femmes dans la résistance de la MEK/ OMPI dans le discours populaire, évalue leur suffisance, et présente un portrait plus précis basé sur des entrevues et une analyse approfondie de l'histoire et des politiques de l'organisation. En d'autres termes, il examine de manière critique comment les femmes dans la résistance de la MEK / OMPI sont capturés par le portrait commun et à travers l'étude des textes rédigés à la première personne par ceux qui ont vécu les expériences et des entrevues démontre la nécessité de réévaluer les récits utilisés pour représenter faussement une organisation et ses membres qui ont radicalisés les notions de l'égalité des sexes et sa relation à la révolution et à la démocratisation.
Cardiac Sympathetic Innervation and PGP 9.5 Expression by Cardiomyocytes in Rats After Myocardial Infarction. Effects of Central MR Blockade

description: Central mechanisms involving aldosterone - mineralocorticoid receptor (MR) activation mediate the increase in sympathetic tone after myocardial infarction (MI). We hypothesized that an increase in cardiac sympathetic activity (CSA) post MI facilitates cardiac sympathetic axonal sprouting, and that central MR blockade attenuates CSA and reduces cardiac sympathetic hyperinnervation post MI. Western blotting and qRT-PCR were used to assess protein and gene expression, and fluorescent immunohistochemistry was used to study changes in sympathetic innervation. Tyrosine hydroxylase (TH) and Norepinephrine transporter protein content in the non-infarcted base of the heart remained unaltered. In contrast, protein gene product (PGP 9.5) protein was significantly increased 2 fold in the base of the heart, and 6 fold in the peri-infarct area at 1 wk post MI, and associated with increased ubiquitin expression. Cardiac myocytes rather than sympathetic axons were identified as the main source of elevated PGP 9.5 expression. At the infarct border sympathetic hyperinnervation was observed with a 4 fold increase in growth associated protein 43 (GAP 43), a 2 fold increase in TH and a 50% increase in PGP 9.5 positive fibers when compared to the epicardial side of the left ventricle in sham rats. Central infusion of the MR blocker eplerenone at 5 ug/day for 9 days post MI markedly attenuated the increase in TH, GAP 43 and PGP 9.5 nerve densities at the infarct border. Central MR blockade may attenuate sympathetic hyperinnervation by several mechanisms, including decreasing CSA post MI, or affecting expression or function of nerve growth factor protein. Marked PGP 9.5 expression occurs in cardiomyocytes early post MI, which may contribute to the increase in ubiquitin and the early cardiac remodeling post MI.

description: The thesis was designed to gain insight into how Alzheimer’s disease influences selfhood from first-personal accounts of illness. The focus of the study was narrowed further by concentrating on the autobiographies of individuals diagnosed with Early-Onset Alzheimer’s disease (EOAD). The purpose of this thesis was to analyze the autobiographies of individuals with EOAD with the aim of understanding their selfhood. In this thesis I argue that, Alzheimer’s disease may influence a change in self, however, the self is not lost entirely. This thesis draws on the philosophical conception of narrated self as it allows for one perpetually constructed self, whereby a change in self does not necessarily mean the self is lost entirely. Through an interpretive analysis of six autobiographical accounts of Alzheimer’s, this thesis demonstrates that Alzheimer’s disease influences a loss of sense of self but that autobiography enables individuals with Alzheimer’s to (re)construct self.

Partition of the Chi-Squared Statistic in a Contingency Table
Creators: name: Colas, Jo Ann
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2014

description: The Pearson statistic, a well-known goodness-of fit test in the analysis of contingency tables, gives little guidance as to why a null hypothesis is rejected. One approach to determine the source(s) of deviation from the null is the decomposition of a chi-squared statistic. This allows writing the statistic as the sum of independent chi-squared statistics. First, three major types of contingency tables and the usual chi-squared tests are reviewed. Three types of decompositions are presented and applied: one based on the partition of the contingency table into independent subtables; one derived from smooth models and one from the eigendecomposition of the central matrix defining the statistics. A comparison of some of the omnibus statistics decomposed above to a χ2(1)-distributed statistic shows that the omnibus statistics lack power compared to this statistic for testing hypothesis of equal success probabilities against monotonic trend in the success probabilities in a column-binomial contingency table.
Ageing population and key workers in health and community services: the role of housing affordability in three areas of Melbourne

description: Many local governments in Victoria have difficulty in attracting home and community care (HACC) staff. Generally understood in local government as a skills shortage, we thought it warranted examination in relation to housing affordability. We surmised that as they are low income workers, declining housing affordability in inner and middle suburbs of Melbourne would influence where HACC staff worked. AHURI (2006) research found that care and aid workers were experiencing housing affordability problems but recommended against occupational-based housing strategies. We decided to investigate the ageing of the population issue, the implications for the supply of 'key workers' in aged care, and the role of housing affordability in that supply. To do this we utilised the health and community services occupation category of the 2006 Census (excluding child care) for three Melbourne metropolitan local governments: inner-city Boroondara and the suburban fringe councils of Casey and Melton. We also examined ABS data for population trends and the Victorian Department of Human Service 2009 Rental Report.

description: Diabetes mellitus (DM) and hyperglycemia contribute to sympathetic nervous system (SNS) activation and cardiovascular dysfunction. SNS activation and increased norepinephrine levels downregulate cardiac β-adrenergic receptors (β-AR). The ADMIRE-HF trial identified reduced cardiac SNS innervation as an independent prognostic marker in heart failure. The β-AR antagonist [3H]-CGP12177 was used to quantify cardiac β-AR in ex vivo biodistribution studies in streptozotocin (STZ)-treated rats after 8 weeks of sustained hyperglycemia, and in the Zucker Diabetic Fatty (ZDF) rat model of type-2 diabetes at the onset of hyperglycemia (10 weeks of age) and after a sustained period of hyperglycemia (16 weeks of age). In some STZ rats, insulin was provided at the onset of hyperglycemia, or after a sustained period of hyperglycemia. Insulin treatment at both time points prevented reduced [3H]-CGP12177 binding (33-38% compared to controls) observed in STZ hyperglycemics. ZDF β-ARs were intact at 10 weeks but became reduced (16-25% relative to the Zucker leans) following 6 weeks of hyperglycemia. This work supports that cardiac β-AR are reduced in models of DM and that restoring insulin signalling to maintain glycemic control can normalize β-AR density whether provided early or after a period of sustained hyperglycemia.

description: With the continuous expansion of data availability in many large-scale, complex, and networked systems, such as surveillance, security, the Internet, and finance, it becomes critical to advance the fundamental understanding of knowledge discovery and analysis from raw data to support decision-making processes. Existing knowledge discovery and data analyzing techniques have shown great success in many real-world applications such as applying Automatic Target Recognition (ATR) methods to detect targets of interest in imagery, drug activity prediction, computer vision recognition, and so on. Among these techniques, Multiple-Instance (MI) learning is different from standard classification since it uses a set of bags containing many instances as input. The instances in each bag are not labeled | instead the bags themselves are labeled. In this area many researchers have accomplished a lot of work and made a lot of progress. However, there still exist some areas which are not covered. In this thesis, we focus on two topics of MI learning: (1) Investigating the relationship between MI learning and other multiple pattern learning methods, which include multi-view learning, data fusion method and multi-kernel SVM. (2) Dealing with the class imbalance problem of MI learning. In the first topic, three different learning frameworks will be presented for general MI learning. The first uses multiple view approaches to deal with MI problem, the second is a data fusion framework, and the third framework, which is an extension of the first framework, uses multiple-kernel SVM. Experimental results show that the approaches presented work well on solving MI problem. The second topic is concerned with the imbalanced MI problem. Here we investigate the performance of learning algorithms in the presence of underrepresented data and severe class distribution skews. For this problem, we propose three solution frameworks: a data re-sampling framework, a cost-sensitive boosting framework and an adaptive instance-weighted boosting SVM (with the name IB_SVM) for MI learning. Experimental results - on both benchmark datasets and application datasets - show that the proposed frameworks are proved to be effective solutions for the imbalanced problem of MI learning.

The basis of these methods is a well-balanced reconstruction operator. Moreover, they introduced a procedure to modify any standard reconstruction operator, like MUSCL, ENO, CWENO, etc., in order to be well-balanced. This strategy involves a non-linear problem at every cell at every time step that consists in finding the stationary solution whose average is the given cell value. In a recent paper, a fully well-balanced method is presented where the non-linear problems to be solved in the reconstruction procedure are interpreted as control problems. The goal of this paper is to introduce a new technique to solve these local non-linear problems based on the application of the collocation RK methods. Special care is put to analyze the effects of computing the averages and the source terms using quadrature formulas. A general technique which allows us to deal with resonant problems is also introduced. To check the efficiency of the methods and their well-balance property, they have been applied to a number of tests, ranging from easy academic systems of balance laws consisting of Burgers equation with some non-linear source terms to the shallow water equations -- with and without Manning friction -- or Euler equations of gas dynamics with gravity effects.

description: Background: Blood donation policy in Canada for gay, bisexual and other men who have had sex with men (gbMSM) has changed progressively in the last decade from indefinite deferral to 3-month deferral from last male-to-male sex. Driven by safety data and overseen by the national regulator, more inclusive policies continue to redress the disparity in donation for gbMSM. At the same time, the need for source plasma to prepare fractionated blood products is growing worldwide. The collection and processing of source plasma ensures greater safety compared to whole blood donation with respect to transfusion-transmitted infection. This greater safety offers an opportunity to evolve policies for gbMSM from time-based to behaviour-based deferral using revised eligibility criteria. However, changing policies does not in itself necessarily guarantee that gbMSM will donate or that staff in donor clinics are ready to support them to do so. In anticipation of a move to behaviour-based donation screening for gbMSM in Canada, we aim to assess the acceptability of and perceived barriers and enablers to source plasma donation using revised screening criteria for gbMSM among key stakeholders to inform policy implementation strategies. Methods: This mixed-methods feasibility study will involve gbMSM and donor centre staff to understand modifiable barriers to implementing more inclusive eligibility criteria. Key informant interviews and surveys will be rooted in the Theoretical Domains Framework to identify modifiable factors associated with source plasma donation motives in gbMSM and training needs in donation centre staff. We will use an integrated knowledge translation approach involving a partnership between researchers, the national blood operator and gbMSM, situating knowledge users as key research team members to ensure their perspectives inform all aspects of the research. Discussion: Our integrated knowledge translation approach will provide a more comprehensive and collaborative understanding of blood operator and gbMSM needs while accelerating the implementation of study findings. Given the historical backdrop of the decades of exclusion of sexually active gbMSM from blood donation, this study has the potential not only to inform a process and policy for gbMSM to donate source plasma, a blood product, but also offers opportunities for new relationships between these knowledge users.

description: The adoption of Artificial Intelligence (AI) in the healthcare service industry presents numerous ethical challenges, yet current frameworks often fail to offer a comprehensive, empirical understanding of the multidimensional factors influencing ethical AI integration. Addressing this critical research gap, this study introduces the Multi-Dimensional Ethical AI Adoption Model (MEAAM), a novel theoretical framework that categorizes 13 critical ethical variables across four foundational dimensions of Ethical AI Fair AI, Responsible AI, Explainable AI, and Sustainable AI. These dimensions are further analyzed through three core ethical lenses: epistemic concerns (related to knowledge, transparency, and system trustworthiness), normative concerns (focused on justice, autonomy, dignity, and moral obligations), and overarching concerns (highlighting global, systemic, and long-term ethical implications). This study adopts a quantitative, cross-sectional research design using survey data collected from healthcare professionals and analyzed via Partial Least Squares Structural Equation Modeling (PLS-SEM). Employing PLS-SEM, this study empirically investigates the influence of these ethical constructs on two outcomes Operational AI Adoption and Systemic AI Adoption. Results indicate that normative concerns most significantly drive operational adoption decisions, while overarching concerns predominantly shape systemic adoption strategies and governance frameworks. Epistemic concerns play a facilitative role, enhancing the impact of ethical design principles on trust and transparency in AI systems. By validating the MEAAM framework, this research advances a holistic, actionable approach to ethical AI adoption in healthcare and provides critical insights for policymakers, technologists, and healthcare administrators striving to implement ethically grounded AI solutions.

description: A randomised controlled trial was conducted to evaluate the administration of the Health Improvement Card (HIC) on lifestyle practices and biometric variables in community-dwelling Chinese participants. Adults living in Shanghai were randomly assigned to either the HIC-intervention or control group. Measurements/assessments were conducted at baseline and three-month follow-up. Supervised physiotherapy students administered the HIC and four standardised questionnaires related to health and wellbeing. Both groups received a health promotion education pamphlet. Based on participants’ HIC biometric and lifestyle scores, students prescribed lifestyle, and exercise advice to the HIC-intervention group. 171 individuals (39 men, 132 women) (mean age 68.4 ± 9.7 y) participated. At follow-up, body mass index (BMI) and waist circumference decreased significantly in the HIC-intervention group. Furthermore, the number of participants in the HIC-intervention group categorised as low risk regarding their physical activity and dietary practices, increased by 32.2% and 20%, respectively. Changes in standardised questionnaire scores did not meet minimum clinically importance differences in either group. This is the first study to demonstrate that HIC-informed health promotion education can improve people’s lifestyle practices, thereby, objective biometric variables. Evaluation of the effect of HIC-informed lifestyle education on some biometric parameters (blood pressure and BMI) may warrant a longer timeframe.
A Recipe for Colonisation: The Impact of Seventeenth-Century Ireland on English Notions of Superiority and the Implications for India

description: This dissertation seeks to consider the colonial experiences of Britain in Ireland and India in a comparative context – to contrast their encounters with, and explorations of, early modern Ireland with the late seventeenth- and eighteenth-century Indian subcontinent. The early experience in Ireland helped shape the developing British belief in their own superiority, leading them to draw distinctions between themselves and other peoples. This laid the groundwork for later endeavours, notably in India. While separated by time and space, these British colonial experiences shared several important characteristics. Early modern Ireland provided the British with important guidelines and models for behaviour, many of which were later adopted in India. The manipulation of history in Ireland, the description of the Gaelic Irish in travel accounts and the application of the law as a tool of reform all provided valuable patterns for the ways in which the British structured their later empire in India.
An Aperture Synthesis Technique for Cylindrical Printed Lens/Transmitarray Antennas with Shaped Beams

description: Printed lens antennas offer the possibility of realizing shaped beam patterns using no more complexity than is required for pencil beam patterns. Shaped beam patterns can be obtained by appropriately determining the complex transmission coefficient required for each cell (or element) of the printed lens, taking into account the varying feed field over the input surface of the lens. Certain ranges of transmission coefficient amplitude and phase are undesirable (eg. too low an amplitude implies a large reflection at the lens input surface). It would be preferable to constrain the range of values that the transmission coefficient can take as an integral part of the lens synthesis procedure, and thus the transmission coefficient itself needs to be the synthesis variable. In this thesis a synthesis technique for doing this is developed based on the method of generalized projections, modified to “operate” in the space of transmission coefficients. This makes it possible to immediately perceive what influence constraints on the actual transmission coefficients have on the possible radiation pattern performance. In addition, an approach that allows one to constrain the transmission coefficient to values that must be selected from an available database of transmission coefficients is incorporated into the synthesis technique.
Juan Tomás Ávila Laurel: Revisiones literarias en la era poscolonial y digital

description: Taking into account an indigenous pre-colonial, a European colonial and a hybrid postcolonial history, in addition to cruel post-independence authoritarian regimes, postcolonial literatures reflect very often the difficult experiences of nations who struggle to find their identities. This is the case of Equatorial Guinea, whose writers, many of them in exile, use their works to raise both national and international awareness about the miserable conditions of a people suffering the consequences of colonialism and two dictatorships. One of these writers is Juan Tomás Ávila Laurel (1966), the subject of this thesis. This dissertation explores how Ávila Laurel’s writings dialogue with Western literary tradition to represent a postcolonial society still in the process of nation-building. In the second chapter, we study Avión de ricos, ladrón de cerdos (2008) as a picaresque novel, and in the third, Arde el monte de noche (2009) as a Bildungsroman. After presenting an overview of the main characteristics of these genres, we demonstrate the similarities of Ávila Laurel’s narratives with the canonical texts, and at the same time, how their rewriting in a postcolonial context leads to fundamental revisions. The final chapter is devoted to Ávila Laurel’s blog Malabo that he has been publishing in the digital journal FronteraD since 2009. We understand his blog as the author’s effort to write political essay, a genre with a longstanding tradition, benefitting from the advantages the new media and communication tools provide. As we argue in this thesis, the author uses Western literary genres that also surfaced in times of deep social and political crisis, to protest against poverty, corruption and abuse of authority, and to denounce hypocrisy and the persistence of colonial and neocolonial structures in Equatorial Guinea. Writing from a hybrid “third space,” Ávila Laurel’s works are, above all, a desire to tell a collective story and create an archive for generations to come.

description: The realizations of the basic representation of the affine general linear Lie algebra on (r x r) matrices are well-known to be parametrized by partitions of r and have an explicit description in terms of vertex operators on the bosonic/fermionic Fock space. In this thesis, we give a geometric interpretation of these realizations in terms of geometric operators acting on the equivariant cohomology of certain Nakajima quiver varieties.
