Real-time damage detection for flexible structures using transient vibrational response.
Creators: name: De Abreu, Robert.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1999
Subjects: subject: Engineering, Mechanical.

description: Flexible structures are often composed of a number of flexible parts connected together by rivets or bolts. Over time, the connections can become loose, creating a danger of structural integrity failure. During system operation, real-time monitoring to detect structural damage is required. In this thesis, a new non-destructive testing method to detect damage in structural connections using piezoelectric actuating/sensing devices is proposed. A thin beam with one end fixed and the other subjected to a variety of boundary conditions is used to investigate the feasibility of this method. The method involves first flexurally exciting the beam and measuring its resulting transient vibrational response using piezoelectric devices, and then determining any change in its one variable boundary condition by comparing the measured response to that of a fixed-fixed (or secure) condition. The size of the difference in the responses indicates the extent of the boundary change. These differences are quantified by the use of damage indices. The proposed transient response approach uses information that cannot be obtained using current steady-state harmonic-based methods. Results of experiments and damage index analyses show that several of the differences in the transient responses of the beam are significantly and monotonically dependent on the level of damage of the connections.
Culture, participation and community development: A case study of Bangladesh.
Creators: name: Orange, Nevin.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1995
Subjects: subject: Sociology, Theory and Methods.

description: The objective of this thesis is to critically examine the notion that "participation" and the other catch phrases found within the language of grass roots development, namely "people's participation", "popular participation", "participatory democracy", "bottom-up" and "self-help" development, etc. are a panaces for development. The position that will be taken is that these concepts and ideas are often "western" in origin and are not always in accordance with the existing structures and socio-cultural values and realities of a given non-western society. In effect, this research will examine and analyse how culture can be seen (from a western perspective) to be an impediment or obstacles to the ideals of "participation" and "grass roots" development, and to critically question and reflect upon the concept of participation and grass roots development in Bangladesh.
Ameriscopia: The Kaleidoscopic Poetic of Edwin Torres between Sound, Language, Image
Creators: name: Polimante, Irene
Publisher: name: Iperstoria
Year: 2020

description: In 2014 the Arizona University Press published Ameriscopia, the last collection of poems by Edwin Torres, in the series “Camino del Sol” (a series completely devoted to latino and latina writers). In this volume, the poet-performer, who’d like to define himself as a lingualisualist, witty undertakes a demanding challenge. Torres offers several samples of performance pieces in print, while he tries to outline a new representation of the composite reality of New York, using his latino belonging as a starting point of an analysis of the contradictions of the whole country. Visions, memories, conversations, together with allusions and glimpses of the main sites of New York help the author to create an imaginary path through the multifaceted, wedge issue of Americanness. Since the language system is pivotal to convey identity, Torres’ linguistic investigation aims to explore the innumerable interconnections between representation and sense, sign and signified, in order to find new solutions for English and Spanish to inter-change, blur and melt into one another. At the core of this study there is a delicate equilibrium between image and sound inside the linguistic context. According to Torres, words, first of all, are images that go hand in hand with sounds and rhythms, and whose emotional and communicative power endorses the ability to create new language patterns. These linguistic models develop inside the margins and the fractures created into language, between languages and by collective consciousness. Moreover, they lay the foundation for Torres’ kaleidoscopic view of reality; for a different representation of a reality on an ongoing transformation and re-definition.

Volatile borders, violated identities: a process of cultural transition
Creators: name: Manzin, Gregoria
Publisher: name: Swinburne
Year: 2024

description: This brief paper will focus on a specific dilemma originated after World War II on the North-Eastern border of Italy. With the 1947 Paris Peace Treaty, the former Italian areas of Istria and Dalmatia were handed over to Tito's Yugoslavia. Some 350.000 Italian citizens left their hometowns to move within Italy's new borders in order to maintain their national identity. They left their homes and entered Italy as 'refugees': strangers in their own country, treated as strangers by fellow Italians. However, a small part of the Italian community in Istria and Dalmatia decided not to leave the area, becoming part of Tito's Socialist Yugoslavia. The Istro-Dalmatian community as a whole became homeless: a new socio-political scenario for the ones who stayed; the same country but a new local reality and a different social status for the one who left; and a new deep borderline to divide in two opposite sides the members of a formerly united local society. Giuliana Zelco and Nelida Milani - representatives of these two parties - raised their voices to call attention on an extremely contemporary issue: how deep can a geographical border cut into our concept of identity? The short stories Una terra nella pelle and L'osteria della Parenzana will be object of this paper: with the means of textual analysis and the support of Jacques Derrida's theories and observations, I will underline the effects that such a political decision triggered on the sense of identity of the individuals involved in the process.

description: In this thesis we present pvFPGA, the first system design solution for virtualizing an FPGA - based hardware accelerator on the x86 platform. The accelerator design on the FPGA can be used for accelerating various applications, regardless of the application computation latencies. Our design adopts the Xen virtual machine monitor (VMM) to build a paravirtualized environment, and a Xilinx Virtex - 6 as an FPGA accelerator. The accelerator communicates with the x86 server via PCI Express (PCIe). In comparison to the current GPU virtualization solutions, which primarily intercept and redirect API calls to the hosted or privileged domain’s user space, pvFPGA virtualizes an FPGA accelerator directly at the lower device driver layer. This gives rise to higher efficiency and lower overhead. In pvFPGA, each unprivileged domain allocates a shared data pool for both user - kernel and inter-domain data transfer. In addition, we propose the coprovisor, a new component that enables multiple domains to simultaneously access an FPGA accelerator. The experimental results have shown that 1) pvFPGA achieves close-to-zero overhead compared to accessing the FPGA accelerator without the VMM layer, 2) the FPGA accelerator is successfully shared by multiple domains, 3) distributing different maximum data transfer bandwidths to different domains can be achieved by regulating the size of the shared data pool at the split driver loading time, 4) request turnaround time is improved through DMA (Direct Memory Access) context switches implemented by the coprovisor.
title: Diego Rivera in the United States: "Working from Within the Enemy Camp"
Creators: name: Dehesa-Avelar, Sarahí

Year: 1998

description: The most notorious twentieth-century Mexican artist and politician, Diego Rivera, stepped up to the international pedestal of art in the late 1920s. Recognized for his revival of mural painting and undeniable compositional skill, the middle-aged Rivera was crowned a Michelangelo of modern art by artists, intellectuals, and admirers of the time. When Rivera traveled to the United States to show off his peacock's tail, the American media also participated readily in the servile flattery of the Mexican master. Yet, as was evident in print media, Rivera's art was revered more for its technical ability to depict Mexico and its culture, than for the revolutionary ideas it was trying to portray. In fact, the media manufactured a cultural argumentation about the artist that was blind to Rivera's desire to spread communism on the walls of capitalist buildings. Thus, when "the greatest living master of fresco painting" exposed a turkey's tail instead of a peacock's, the media changed the fawning to vitriol. As a result, Rivera's career in the United States was ephemeral.

Dubbing British Humour and Culture: A Re-reading of Four Weddings and a Funeral
Creators: name: Leotta, Paola Clara
Publisher: name: Iperstoria
Year: 2020
Subjects: humour; four weddings and a funeral; translation strategies

description: In the literature on the translation of humour, much attention is devoted to questions relating to its (un)translatability, especially of audio-visual texts, where the degree of difficulty increases because of their inherent characteristics, such as time or space limitation in dialogues and scenes. The aim of this paper is to explore the transposition of Verbally-Expressed Humour) in Four Weddings and a Funeral (Mike Newell 1994), from a pragmatic-discursive perspective (Chiaro 1992; 2007), which enables light to be shed also on the cultural factors (Toury 2012) behind the choices of the elements for translating humour. The analysis of a corpus of selected scenes is carried out by comparing the English and Italian (dubbed) versions, focusing on three main strategies (Pavesi 2005) followed by translator-adaptors in rendering humour in Italian, namely equivalence, downgrading/downtoning, and omission, which are discussed both qualitatively and quantitatively. For the purposes of this paper, I refer to figures of speech, lip synchronization, swear words, puns, idioms, proverbs, quotes from songs, film titles, famous celebrities, whenever they are used for humorous purposes. The hypothesis is that the difficulties inherent in the art of screen translation are an important vehicle in weaving relations of cultural identity and in conveying them to the audience from an intertextual perspective. What primarily emerges as a result is the translators’ preference for the strategy of equivalence as well as for that of “exemplification”. It is clearly shown that innovative thinking and creative decision-making on the part of translators can result in a successful translation, even with a culturally bound element in a contextually bound medium.

Subjects: subject: Anthropology, Cultural.

description: Pastoral nomadism as a way of life is no longer as prevalent as it once was, but it is still an important phenomenon in the Middle East. In the last few decades, the rate of sedentarization among nomads has increased as a result of technological progress in agriculture and pastoralism, as well as political, social, ecological, and economic factors. This study focuses on the Qashqa'i nomads of Iran and their migration as an example for the Middle East. It deals with both nomadic and sedentary Qashqa'i people and examines the causes and consequences of their migration. Push-pull theory, is used as an analytical framework for the research. As a part of the methodology, logit models are employed in statistical analysis. A survey questionnaire was administered in order to develop a comprehensive picture of nomadic people at the places of origin and destination. The research attempts to generate several 'general profiles' of nomads depending upon their location--either at the place of origin or at the place of destination. These profiles can be used to increase understanding of the causes and consequences of Qashqa'i migration, as well as the processes of cultural change which occur when nomadic people 'settle' in urban areas. For the Qashqa'i the major economic, social, and environmental push factors are poverty, lack of educational institutions, and hardship of climate. The main pull factors are centred around their desire to improve educational, job, and accessibility criteria. The research also revealed that Qashqa'i culture is slowly adapting to urban ways. An examination of public migration policy shows that a more systematic approach is needed to questions of inter- and intra-regional development and migration issues.
Delayed ettringite formation in Portland cement products.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1996
Subjects: subject: Engineering, Civil.

description: The thesis presents the results of an extensive research program on the deterioration of Portland cement concrete due to delayed ettringite formation (DEF). The study focuses on three aspects: (i) the mechanisms of DEF; (ii) a test method to determine the DEF potential of a given cement; (iii) some preventive measures to reduce the deterioration of portland cement products due to DEF. The research work indicates that C-S-H gel will adsorb sulfate fast at high temperature resulting in quick depletion of the gypsum phase in the portland cement-water system. Sulphate absorbed at high temperature is desorbed more slowly than that adsorbed at normal temperatures. Slower release of sulfate from an internal sulfate source may be a critical condition for DEF in high temperature cured Portland cement paste. Nucleation of a crystal requires less surface energy in a crack than in the cement paste matrix. Sulfate ions, after release from the C-S-H gel, will diffuse into the nearest microcrack and react with the Al-bearing materials in the crack to nucleate and crystallize ettringite. Growth of ettringite crystals opens the crack and damages the cement products. A test method to determine the expansion potential, due to delayed ettringite formation (DEF), of portland cements initially moist-cured at high temperatures was developed. Expansion of cement mortars made with eight different portland cements was investigated. Different test parameters, such as, curing temperature, type of sand, sand/cement ratio, specimen size and pre-treatment, were studied to select the optimal test conditions and procedures. Expansion/time criteria to evaluate the DEF potential of a given cement from the results of this test method are discussed. Siliceous materials can be used in portland cement products to reduce or eliminate deterioration due to DEF. Different siliceous materials have different characteristics relevant to the reduction of the deleterious expansion. The granulated blast-furnace slag, ggbs, and Class F fly ash are more effective in reducing the DEF expansion than Class C fly ash, silica fume and natural zeolite. The expansion of the mortar containing a siliceous material appears to be much delayed. Therefore long-term expansion should be considered in the selection of a siliceous material for use in a DEF-suspect cement. Microcracks play an important role in the expansion due to DEF. Control of microcracks using wollastonite micro-fibres should reduce the expansion of a DEF-suspect cement mortar.

description: Caffeic acid (CA) and chlorogenic acid (CGA) are phenolic compounds claimed to be responsible for the metabolic effects of coffee and tea consumption. Along with their structural similarities, they share common mechanisms such as activation of the AMP-activated protein kinase (AMPK) signaling. The present study aimed to investigate the anti-obesity potential of CA and CGA as co-treatment in human adipocytes. The molecular interactions of CA and CGA with key adipogenic transcription factors were simulated through an in silico molecular docking approach. The expression levels of white and brown adipocyte markers, as well as genes related to lipid metabolism, were analyzed by real-time quantitative PCR and Western blot analyses. Mechanistically, the CA/CGA combination induced lipolysis, upregulated AMPK and browning gene expression and downregulated peroxisome proliferator-activated receptor γ (PPARγ) at both transcriptional and protein levels. The gene expression profiles of the CA/CGA-co-treated adipocytes strongly resembled brown-like signatures. Major pathways identified included the AMPK- and PPAR-related signaling pathways. Collectively, these findings indicated that CA/CGA co-stimulation exerted a browning-inducing potential superior to that of either compound used alone which merits implementation in obesity management. Further, the obtained data provide additional insights on how CA and CGA modify adipocyte function, differentiation and lipid metabolism.

description: Misalignment of gas and stellar rotation in galaxies can give clues to the origin and processing of accreted gas. Integral field spectroscopic observations of 1213 galaxies from the Sydney-AAO Multi-object Integral field spectrograph (SAMI) Galaxy Survey show that 11 per cent of galaxies with fitted gas and stellar rotation are misaligned by more than 30 degrees in both field/group and cluster environments. Using SAMI morphological classifications and Sersic indices, the misalignment fraction is 45 +/- 6 per cent in early-type galaxies (ETGs), but only 5 +/- 1 per cent in late-type galaxies (LTGs). The distribution of position angle offsets is used to test the physical drivers of this difference. Slower dynamical settling time of the gas in elliptical stellar mass distributions accounts for a small increase in misalignment in early-type galaxies. However, gravitational dynamical settling time is insufficient to fully explain the observed differences between ETGs and LTGs in the distributions of the gas/stellar position angle offsets. LTGs have primarily accreted gas close to aligned rather than settled from misaligned based on analysis of the skewed distribution of PA offsets compared to a dynamical settling model. Local environment density is less important in setting the misalignment fractions than morphology, suggesting that mergers are not the main source of accreted gas in these discs. Cluster environments are found to have gas misalignment driven primarily by cluster processes not by gas accretion.

Year: 2023

description: There are inconsistencies in how newborns are managed following exposure to varicella, ranging from reassurance and observation to administration of varicella zoster immunoglobulin (VZIG) and admission to hospital for varying length courses of IV aciclovir. In this article, we review the evidence for risk to non-immune mothers, the fetus and newborns who had different types of exposure to varicella, with recommendations for management and treatment of confirmed neonatal chickenpox. Hospitalised preterm babies exposed to varicella should receive VZIG. Administration can otherwise be limited to pregnant non-immune women, or to newborns if there is development of maternal chickenpox from 5 days prior to delivery up to 48 hours post-delivery. Intravenous aciclovir is only recommended in cases of newborn disease despite VZIG, or in severe disease. The use of VZIG may not prevent varicella, but may reduce severity of disease.
Geotechnical characteristics of recycled glass in road pavement applications

Publisher: name: Swinburne

description: Current levels of natural aggregates production are under threat due to tighter restrictions on planning issues related to quarrying of virgin materials. There is now a developing emphasis on environmental management which has resulted in growing pressure to investigate the viability of reuse of all categories of waste materials. Recycled glass continues to be one of the principal waste products generated by the public and its reuse applications are urgently sought by the recycling industry. Recycled glass is a waste material produced in large quantities in municipal and industrial areas in Australia and worldwide. Currently in the state of Victoria, Australia, 186,000 tonnes of recycled glass are stockpiled annually and these stockpiles are growing. However, there is little known reuse application for recycled glass in pavement subbase applications due to limited knowledge concerning its geotechnical properties. The reuse of recycled glass in road pavement applications will provide an opportunity to reduce the unnecessary wastage of not only diminishing virgin materials stocks but also valuable land-fill space. Using recycled glass in road pavement applications would eliminate the need for expensive sorting offering an opportunity to use it as aggregate in locations where virgin aggregate sources are scarce. The geotechnical characteristics of up to 50% recycled glass (by mass) in blends with crushed rock and recycled crushed concrete were obtained from an extensive laboratory testing including high level of tests such as static triaxial tests and repeated load triaxial tests. The research also explores the performance of recycled glass blends in field trial pavement sections with up to 30% recycled glass as an additive into crushed rock and recycled crushed concrete mixes for pavement base applications. The research also explores the performance of granular materials using finite element modelling. The findings of this research suggest that up to 15% content of recycled glass with the maximum particle size of 4.75 mm could be safely added in blends with recycled crushed concrete and crushed rock. Test results show that the extent of breakdown occurring in the blends in excess of 15% recycled glass is on the limit of what would be acceptable for this material. It might be possible to increase the percentages of recycled glass but this depends on the results of future field trials.

description: The field of stem cell biology is continuously expanding, encompassing not only the traditional study of hematopoietic and fetal cells, but also the investigation of adult stem cells from a variety of tissue sources. The definitions and conventions adopted by the field of hematopoiesis have served as a framework for the more recent discoveries in adult stem cell biology. As such, stem cells are defined as immature progenitor cells capable of long term self-renewal and pluripotent differentiation. Using Fluorescence Activated Cell Sorter (FACS) analysis, a sub-population of distinct Hoechst dye-excluding cells, termed the 'side population' (SP), has been isolated from bone marrow (BM) (Goodell et al., 1996). These verapamil-sensitive cells are highly enriched in stem cell activity and have the capacity for lineage conversion. The potential for these cells to play a role in adult tissue maintenance and repair has been established in skeletal muscle, liver and brain. Here we report the existence of endogenous SP cells within the adult myocardium with similar but not identical characteristics to SPs from other adult tissues. These features include the capacity for cardiomyocyte differentiation and the expression of cell surface markers such as Sca-1 and CD34, but not hematopoietic lineage markers Gr-1, Mac-1 and CD4. Conversely, these cardiac-derived SP cells do not express the hematopoietic stem cell (HSC) markers c-kit and CD45. Furthermore, fusion but not transdifferentiation of these myocardial SP cells with skeletal myoblasts was observed. These results offer the first experimental evidence of a resident population of myocardial stem cells and suggest a potential for therapeutic applications in cardiac disease.

description: There are many software visualization tools available today to help software engineers to explore software systems. However, when a system is huge, some of these tools do not satisfy the exploration requirements. The big problem is that the techniques the tools use do not provide an effective display and access mechanism to handle huge information spaces within the limitations imposed by available screen space. To alleviate the problem, this thesis describes methods that help users to explore huge software systems. In particular, we apply dynamic browsing incorporating such details as an extra result box mechanism, plus pattern based searching to help users to handle large query results. Then the thesis introduces the algorithms we apply to generate the layouts. We propose the radial angle model to visualize the internal structures of rooted trees. Also we apply the spring model to visualize the external structures among rooted trees. Next, the thesis describes various animation methods we use to smooth the transitions, track the focus of exploration, clarify unexpected results, and illustrate complex operations. In addition, we modify traditional camera animation, and propose an animation timing scheme 'slow-in fast-out' to exaggerate the reality. Next, the thesis describes a series of experiments we conducted to assess the effectiveness of the browsing, layout algorithm and animation techniques we implemented. Finally the thesis describes how we use the analysis of the experiment results to guide our future research.
The attempted formation of quaternary centers via a novel intramolecular para-C-alkylation and the use of the aza-Ireland-Claisen rearrangement in the attempted formation of adjacent stereocenters

description: The formation of quaternary centers is a formidable challenge. Once these quaternary centers become part of a spirocyclic system, the project becomes even more challenging. The intramolecular para-C-alkylation has been previously used with success. However, no literature precedence is available for an asymmetric version of this reaction. The attempts in synthesizing molecules similar to 123 by using such methodologies are described herein.* Also described is a second project which involved the effective use of the aza-Ireland-Claisen rearrangement in constructing medium-sized rings. These rings can be easily hydrolyzed to produce useful, functionalized synthetic fragments 157 containing two adjacent stereocenters as shown below.* *Please refer to dissertation for diagrams.
Text classification on imbalanced data: Application to systematic reviews automation

description: Systematic Review is the basic process of Evidence-based Medicine, and consequently there is urgent need for tools assisting and eventually automating a large part of this process. In the traditional Systematic Review System, reviewers or domain experts manually classify literatures into relevant class and irrelevant class through a series of systematic review levels. In our work with TrialStat, we apply text classification techniques to a Systematic Review System in order to minimize the human efforts in identifying relevant literatures. In most cases, the relevant articles are a small portion of the Medline corpus. The first essential issue for this task is achieving high recall for those relevant articles. We also face two technical challenges: handling imbalanced data, and reducing the size of the labeled training set. To address these issues, we first study the feature selection and sample selection bias caused by the skewness data. We then experimented with different feature selection, sample selection, and classification methods to find the ones that can properly handle these problems. In order to minimize the labeled training set size, we also experimented with the active learning techniques. Active learning selects the most informative instances to be labeled, so that the required training examples are reduced while the performance is guaranteed. By using an active learning technique, we saved 86% of the effort required to label the training examples. The best testing result was obtained by combining the feature selection method Modified BNS, the sample selection method clustering-based sample selection and active learning with the Naive Bayes as classifier. We achieved 100% recall for the minority class with the overall accuracy of 58.43%. By achieving work saved over sampling (WSS) as 53.4%, we saved half of the workload for the reviewers.

description: Background: Lodgepole pine (Pinus contorta) and interior spruce (Picea glauca, Picea engelmannii, and their hybrids) are distantly related conifer species. Previous studies identified 47 genes containing variants associated with environmental variables in both species, providing evidence of convergent local adaptation. However, if the intensity of purifying selection varies with the environment, clines in nucleotide diversity could evolve through linked (background) selection that would yield allele frequency-environment signatures resembling local adaptation. If similar geographic patterns in the strength of purifying selection occur in these species, this could result in the convergent signatures of local adaptation, especially if the landscape of recombination is conserved. In the present study, we investigated whether spatially/environmentally varying purifying selection could give rise to the convergent signatures of local adaptation that had previously reported. Results: We analyzed 86 lodgepole pine and 50 interior spruce natural populations spanning heterogeneous environments in western Canada where previous analyses had found signatures of convergent local adaptation. We estimated nucleotide diversity and Tajima’s D for each gene within each population and calculated the strength of correlations between nucleotide diversity and environmental variables. Overall, these estimates in the genes with previously identified convergent local adaptation signatures had no similar pattern between pine and spruce. Clines in nucleotide diversity along environmental variables were found for interior spruce, but not for lodgepole pine. In spruce, genes with convergent adaption signatures showed a higher strength of correlations than genes without convergent adaption signatures, but there was no such disparity in pine, which suggests the pattern in spruce may have arisen due to a combination of selection and hybridization. Conclusions: The results rule out purifying/background selection as a driver of convergent local adaption signatures in lodgepole pine and interior spruce.

description: A β-cyclodextrin-decorated magnetic activated carbon adsorbent was prepared and characterized using various analytical techniques (X-ray diffraction (XRD), scanning electron microscopy–electron diffraction spectroscopy (SEM-EDS) and transmission electron microscopy (TEM)), and the adsorbent was used in the development of a magnetic solid-phase microextraction (MSPE) method for the preconcentration of estrone, β-estradiol, hydrocortisone and progesterone in wastewater and river water samples. This method was optimized using the central composite design in order to determine the experimental parameters affecting the extraction procedure. The quantification of hormones was achieved using high-performance liquid chromatography equipped with a photodiode array detector (HPLC-DAD). Under optimum conditions, the linearity ranged from 0.04 to 300 µg L−1 with a correlation of determinations of 0.9969–0.9991. The limits of detection and quantification were between 0.01–0.03 and 0.033–0.1 µg L−1, with intraday and interday precisions at 1.1–3.4 and 3.2–4.2. The equilibrium data were best described by the Langmuir isotherm model, and high adsorption capacities (217–294 mg g−1) were obtained. The developed procedure demonstrated high potential as an effective technique for use in wastewater samples without significant interferences, and the adsorbent could be reused up to eight times.

description: Neuroradiologists rely on scanned images of the human brain to diagnose many pathologies. The images, even those collected in 3-dimensions, are typically displayed as a 2-dimensional collage of slices and much of the intrinsic 3-D structure of the data is lost. Image Atlases are commonly used to delineate and label Volumes Of Interest (VOIs) in 3-dimensional, slice-type, medical data sets. They can serve many purposes: to highlight important regions, to quantify the size and shape of structures in the images, to define a surface for 3-D rendering and to help in navigation through a series of images. To perform these functions, an individual atlas is required for each data set. The purpose of this thesis is to develop a link between the volume data and the individual atlas associated with each set of images. An automatic method of building an individual atlas from the volume data is proposed. The method uses a data-driven, bottom-up segmentation to produce a primitive atlas followed by a knowledge-driven, top-down merging and labelling stage to refine the primitive atlas into an individual atlas. The system was implemented in software using an object-oriented approach which allowed for a high quality user interface and a flexible and efficient implementation of the concepts of an atlas and a VOI. Tests were performed to judge the quality of the segmentations and of the atlas labellings. The results prove that the individual atlases created using the proposed method are sufficiently accurate to aid in visualizing 3-D structures in medical data sets and to quantify the sizes of these structures.

description: A biometric system is designed to accurately identify people based on human physiological features such as face, iris, fingerprint and voice recognition. Iris recognition is considered to have the highest identification accuracy and commercial iris recognition systems have been deployed in many applications, like passports and border control. One of the key performance limitations in iris recognition is the low image quality, including rotated iris images, partial eyelash and eyelid occlusions. We developed an algorithm to accurately detect the eyelash occlusion and eliminate these eyelash occluded regions from the recognition. The resulting detection error tradeoff curve showed an improved error rate in most of the false match (FMR) rate range. We also examined two methods of rotational invariant feature extraction: one based on the covariance features and one based on the Fourier transform magnitudes. In addition, we evaluated the errors in the localizations of circles. The system performance after correction was re-evaluated, and a marginal improvement was observed, in terms of the rank-1 identification rate, the DET curve, and the cumulative match curve. Moreover, we tested a progressive segmentation scheme. It gradually increased the area of the iris region that was segmented for the inter-class and intra-class comparisons. It showed that in a particular range of an iris image area, the system performance improves rapidly. Overall, this thesis suggests that it is possible to improve the iris recognition with low quality iris images. It also provides several research directions for future work.

description: A MIMO-CDMA system with Nt transmit antennas can transmit Nt symbols on a given signaling interval, and those N t symbols are referred to as a message vector. In conventional MIMO-CDMA systems, a message group is spread by using orthogonal direct sequence spreading codes. In this thesis, less known and recently introduced the parity-bit-selected spreading and the permutation spreading techniques are used for MIMO-CDMA system. This thesis develops the closed form theoretical expressions for parity-bit-selected spreading and permutation spreading techniques. We also introduce new design strategies for permutation spreading technique. In the MIMO-CDMA system employing parity bit selected spreading, rather than assigning each transmit antenna with different spreading sequences, the message vector is input to a systematic block encoder whose output parity bits select the spreading sequence to be used. In other words, with a given message vector, all the transmit antennas would use the same spreading sequence. In the MIMO-CDMA system using permutation spreading, rather than using the parity bits to select one spreading sequence, the parity bits are used to select Nt different spreading sequences from a set of spreading sequences. A unique permutation of spreading sequences is assigned for different parity bits. Compared to MIMO-CDMA systems employing conventional spreading method, the simulation results show that, in frequency-nonselective Rayleigh fading channel, parity bit selected spreading improves the system performance, while permutation spreading can further improve the system performance in both single-user and multi-user environments.

description: The topic of autonomous driving currently draws much media attention, and automobile manufacturers and component suppliers are working on the realisation of autonomous vehicles. On the way to a fully autonomously driving vehicle, different levels of au- tomated driving have to be mastered as depicted in Tab. 1 and defined, for example, by [1]. With an increasing automation level, the execution, monitoring, and fallback performance are increasingly handled by the system and not by the human driver, in- creasing the requirements for the sensor system. As shown e.g. in [2] radar sensors are a key technology to enable Level 5 full automation. In contrast to video cameras and laser scanners, a radar sensor is nearly independent of severe weather and light conditions and even remains operational in complete darkness and snowfall. By exploiting the reflections of the electromagnetic waves between road surfaces and the underbody of vehicles it is even possible to detect hidden targets behind other vehicles.
