Full textAbstract:
The use of color coded prompts to influence students' food selections in choosing a balanced meal was investigated. Yellow, green, blue, and orange dots, representing the four major food groups, grains, fruit and vegetables, dairy, and meat respectively were displayed at the point-of-selection on food entree cards along the serving line of a college dining hall. Two grain servings, two fruit/vegetable servings, one dairy serving, and one meat serving, were suggested as the optimal combination for a balanced meal. The results indicated that the prompts, although noticed and understood by the majority of the students, did not significantly influence their food selections. These findings are inconsistent with earlier studies substantiating the effectiveness of color coded prompts at the point-of-selection in influencing food choices. Implications are discussed.

Uma das estratégias mais eficientes de alocação de registradores é baseada na coloração por grafos. Este trabalho descreve uma nova técnica, denominada color flipping, para trocar as cores em um grafo de interferência que minimiza a inserção de código spill. Para isso, um alocador Chaitin-Briggs foi desenvolvido de duas maneiras: com a etapa de troca de cores ativada e desativada. Foram realizados experimentos com um conjunto de 27.921 grafos de programas reais e experimentos com os benchmarks do SPEC CPU2006 no LLVM. Os resultados mostraram que em alguns casos foi possível reduzir a quantidade de spill em mais de 12%.Graph coloring is one of the most effectiveness approaches to perform register allocation. This work describes the color flipping technique a new approach to minimize spill code insertion. To evaluate the impact of using color flipping in the graph coloring register allocator, a Chaitin-Briggs allocator has been developed in two ways - with the color flipping and without the color flipping. Experiments with a set of 27,921 graphs of real programs and with the LLVM framework over the benchmarks of SPEC CPU2006 were performed. In some cases, our results showed over 12% of reduction in spill code insertion.

Full textAbstract:
A Benitaka é uva de mesa importante, mas apresenta deficiência no desenvolvimento da cor vermelha devido à inibição da produção de antocianinas quando cultivada em áreas subtropicais. A aplicação exógena de reguladores de crescimento, como o ácido abscísico (ABA), pode ser um dos métodos utilizados para superar esse problema. O objetivo deste trabalho foi estudar a ação do isômero do ácido (S) -cis-abscísico (S-ABA) sobre ao desenvolvimento de cor, concentração de antocianinas e melhoria da qualidade da uva de mesa 'Benitaka', e determinar o tempo mais adequado para aplicação do S-ABA para esta cultivar. Os experimentos foram conduzidos em um vinhedo comercial localizado em Marialva, PR, e as videiras foram treinadas em um sistema de treliça aérea, espaçadas em 3,0 × 6,0 m. Os testes foram realizados durante duas safras consecutivas (safra regular de 2015 e fora de época de 2016), e os tratamentos incluíram aplicações de S-ABA 400 mg.L-1, como segue: Controle (sem aplicação); Em pré-veraison (PRV) (7 dias antes de veraison); no momento do veraison (V); e no pós-veraison (POV) (7 dias após V). Uma segunda aplicação foi realizada para todos os tratamentos 10 dias após a primeira aplicação, exceto para o controle. O delineamento experimental foi em blocos ao acaso, incluindo: acúmulo total e diário de antocianinas, índice de cor de uvas vermelhas (CIRG) e desenvolvimento diário de CIRG, taxas semanais e diárias de acumulação de antocianinas, taxas semanais e diárias do CIRG, desenvolvimento da luminosidade (L *), croma (C *) e ângulo de matiz (h °), massa, comprimento, largura, firmeza, sólidos solúveis totais (SST), acidez titulável (TA), índice de maturação (SST / AT) e polifenóis totais de bagas . Os dados foram submetidos ao teste ANOVA e as médias comparadas pelo teste de Tukey a 5% de significância. A aplicação exógena de S-ABA no PRV ao POV pode aumentar significativamente os atributos de cor, bem como o teor total de antocianinas da uva de mesa 'Benitaka', mas as aplicações no PRV e no V fornecem uma maior resposta. Existe uma forte correlação entre o CIRG e a antocianina da casca das bagas, enquanto as características físico-químicas das bagas não são afetadas significativamente pelo uso de S-ABA. A firmeza da fruta varia ligeiramente em resposta à aplicação da S-ABA, mas não compromete a qualidade da baga para uso comercial. Durante as colheitas regulares e fora de época da uva de mesa 'Benitaka', a aplicação exógena de S-ABA em qualquer momento do V, especialmente em PRV ou V, pode melhorar significativamente a taxa semanal e diária de acumulação de antocianina, bem como cor no desenvolvimento das bagas. Outras propriedades químicas das uvas, isto é, a evolução de SST, AT e SST / AT, não são afetadas pelo uso de S-ABA e seguem um padrão previsível em relação aos dias de amadurecimento das bagas.Benitaka is an important table grape, but shows lack of color development due to anthocyanin inhibition when grown under subtropical areas. Exogenous application of growth regulators, like abscisic acid (ABA), is one of the methods used to overcome this problem. The aim of this work was to study the dynamics of (S)-cis-abscisic acid isomer (S-ABA) in relation to color development, anthocyanin concentration and quality improvement of Benitaka table grape, and to determine the exact timing for S-ABA application that is best suited for this cultivar. The experiments were conducted in a commercial vineyard located at Marialva, PR, Brazil, and the vines were trained in an overhead trellis system, spaced at 3.0 × 6.0 m. Trials were carried out during two consecutive seasons (regular season of 2015 and off-season 2016), and treatments included applications of S-ABA 400 mg.L-1, as follow: Control (no application); At pre-veraison (PRV) (7 days before veraison); At veraison (V); and At post-veraison (POV) (7 days after V). A second application was performed for all treatments 10 days after the first application, except for the control treatment. A randomized block design was used for both experiments and analysis included: total and daily anthocyanins accumulation, color index of red grapes (CIRG) and daily CIRG development, weekly and daily rates of anthocyanin accumulations, weekly and daily rates of CIRG development lightness (L*), chroma (C*) and hue angle (h°), mass, length, width, firmness, total soluble solids (TSS), titratable acidy (TA), index of maturation (TSS/TA) and total polyphenols of berries. The data was subjected to ANOVA test and the means were compared using Tukeys test at 5% level of significance. The exogenous application of S-ABA from PRV to POV can significantly enhances the color attributes as well as total anthocyanin contents of Benitaka table grape, but applications at PRV and at V provide a higher response. A stronger correlation exists between CIRG and anthocyanin of berry skin, whereas the physicochemical characteristics of berries are not affected significantly by the use of S-ABA. The berry firmness slightly varies in response to the S-ABA application, but not to the extent where it compromises the berry quality for commercial use. During both regular and off-season crops of Benitaka table grape, the exogenous application of S-ABA at any time of V, especially at PRV or at V, can significantly improve the weekly and daily rate of anthocyanin accumulation as well as color development of the berries. Other chemical properties of grapes, i.e., TSS, TA and TSS/AT evolution, are not affected by the use of S-ABA, and follow a predictable pattern in relation to days of berries ripening.

Full textAbstract:
Les travaux de cette thèse portent sur l'amélioration et l'optimisation de l'algorithme de suivi d'objet couleur Mean-Shift à la fois d’un point de vue robustesse du suivi et d’un point de vue architectural pour améliorer la vitesse d’exécution. La première partie des travaux a consisté en l'amélioration de la robustesse du suivi. Pour cela, l'impact des espaces de représentation couleur a été étudié, puis une méthode permettant la sélection de l'espace couleur représentant le mieux l'objet à suivre a été proposée. L'environnement de la cible changeant au cours du temps, une stratégie est mise en place pour resélectionner un espace couleur au moment opportun. Afin d'améliorer la robustesse dans le cas de séquences particulièrement difficile, le Mean-Shift avec stratégie de sélection a été couplé avec un autre algorithme plus coûteux en temps d'exécution : le suivi par covariance. L’objectif de ces travaux est d’obtenir un système complet fonctionnant en temps réel sur processeurs multi-cœurs SIMD. Une phase d’étude et d'optimisation a donc été réalisée afin de rendre les algorithmes paramétrables en complexité pour qu’ils puissent s’exécuter en temps réel sur différentes plateformes, pour différentes tailles d’images et d’objets suivi. Dans cette optique de compromis vitesse / performance, il devient ainsi possible de faire du suivi temps-réel sur des processeurs ARM type Cortex A9The work of this thesis focuses on the improvement and optimization of the Mean-Shift color object tracking algorithm, both from a theoretical and architectural point of view to improve both the accuracy and the execution speed. The first part of the work consisted in improving the robustness of the tracking. For this, the impact of color space representation on the quality of tracking has been studied, and a method for the selection of the color space that best represents the object to be tracked has been proposed. The method has been coupled with a strategy determining the appropriate time to recalculate the model. Color space selection method was also used in collaboration with another object tracking algorithm to further improve the tracking robustness for particularly difficult sequences : the covariance tracking which is more time consuming. The objective of this work is to obtain an entire real time system running on multi-core SIMD processors. A study and optimization phase has been made in order to obtain algorithms with a complexity that is configurable so that they can run in real time on different platforms, for various sizes of images and object tracking. In this context of compromise between speed and performance, it becomes possible to do real-time tracking on processors like ARM Cortex A9

The ability to read code is an important skill in programming, and is said to be affected by the coding environment and interface. This thesis investigates the impact of colour themes on code readability, comparing dark text on a light background to light text on a dark background. An experiment was performed where participants solved code comprehension tasks while recorded using eye tracking. Results indicated no significant differences in accuracy or time between the two colour themes. Similarly, the eye tracker recordings showed no significant difference in eye movement patterns between colour themes.Läsning av källkod är en viktig färdighet inom programmering och sägs påverkas av programmeringsmiljöns gränssnitt.

Full textAbstract:
It is well known that the colour preferences of ganglion and LGN cells do not match the four perceptually simple colours red, green blue and yellow. It is also known that although colour perception is distorted in the peripheral visual field, there are four hues that appear stable with eccentricity. These are defined as peripherally invariant hues. Both of these observations must in some way reflect the physiological substrate of neurons at different stages of the primary visual pathway. The experiments described here are aimed at understanding the link between the physiology and the perception of colour by studying the characteristics of peripheral colour visionThe following questions have been addressed; i) to what extent does colour matching rely on the retinal physiological substrate? ii) what is the reason for the discrepancy between invariant and unique green and how is cone contrast linked to this paradox? iii) how are the `special' hues (invariant and unique) related to human evolution? iv) how does peripheral colour vision vary between males and females?An asymmetric colour matching paradigm and a colour naming task have been employed. In the colour matching task, 24 chromatic axes of variable purity are used. Observers match the chromaticity of a 3 degree peripheral spot with that of a 1 degree parafoveal spot. The results are expressed in terms of hue rotation, saturation match and cone contrast. In the colour naming experiment the observers name 40 chromatic axes as either red, blue, green or yellow and colour naming functions are derived. The central maxima of these functions are defined as the unique hues. The results suggest that colour matching and cone opponency reflect the characteristics of the retinal neural network as they exhibit nasal-temporal asymmetries, similar to known physiological asymmetries. Although three of the peripherally invariant hues match the unique counterparts, invariant and unique green are markedly different for all observers. In an important control experiment unique hues are shown to be stable with eccentricity and purity. This confirms that these attributes are not confounding factors for the observed discrepancy between invariant and unique green. Unlike for the other 'special' hues the RMS cone contrast of invariant green differs markedly between parafoveal and peripheral targets. It is likely that the cone contrast remains unchanged only if the stimuli excite the same number of cones. Two invariant and two unique hues (blue and yellow) fall on the daylight locus suggesting that discrimination in these regions of the colour space is strongly influenced by terrestrial illumination. Moreover, the inter-individual variability is found to be minimised around the daylight locus showing that the blue-yellow system is more stable across colour normal populations than the red-green system. A statistically significant difference is demonstrated between the peripheral colour vision of males and females. This may be attributed to the M-cone polymorphism which in addition to X-chromosome inactivation, results in more than three cone types in the female retina.

Full textAbstract:
Contrast-enhanced magnetic resonance angiography (MRA) is used to obtain images showing the vascular system. To detect stenosis, which is narrowing of for example blood vessels, maximum intensity projection (MIP) is typically used. This technique often fails to demonstrate the stenosis if the projection angle is not suitably chosen. To improve identification of this region a color-coding algorithm could be helpful. The color should be carefully chosen depending on the vessel diameter.
In this thesis a segmentation to produce a binary 3d-volume is made, followed by a distance transform to approximate the Euclidean distance from the centerline of the vessel to the background. The distance is used to calculate the smallest diameter of the vessel and that value is mapped to a color. This way the color information regarding the diameter would be the same from all the projection angles.
Color-coded MIPs, where the color represents the maximum distance, are also implemented. The MIP will result in images with contradictory information depending on the angle choice. Looking in one angle you would see the actual stenosis and looking in another you would see a color representing the abnormal diameter.

Full textAbstract:
This research investigated both cognitive and affective influences of alternative color combinations in a search task paradigm. The effects of re-mapping the existing, comparatively arbitrarily color codes of baggage X-ray images, were explored. Alternative color-codes were evaluated for improving the economy of visual search in X-ray baggage screening. Using a 2 x 2 between-groups design, the perceptual aspects of color-codes varying in degree of visual agreeability (accordant or discordant) and color contrast (high or low) were examined in terms of effectiveness (detection accuracy) and efficiency (reaction time). Three hypotheses were put forth; two postulated main effects for color contrast and for visual agreeability, and a third postulated an interaction. Additionally, for comparison purposes, a fifth group of participants was presented with a stimulus condition that represented the current industry standard for colorizing X-ray images. Out of 100 volunteers, data were usable for 95 participants who had been randomly assigned to one of five conditions. All participants were exposed to the same screening task. The screening task required participants to view 153 X-ray images in random order. Of these images, 36 contained a single threat item (knife, scissor, gun) among clutter. Analyses of variance revealed significant differences between conditions with respect to detection accuracy. Implications are that high-color contrast improves detection accuracy; specifically with respect to correct rejections, and that this effect on performance can be moderated by psycho-emotional mechanisms. Specifically, the impact of color-contrast was significantly more pronounced under conditions of accordant color combinations. Theoretical underpinnings and applications to other domains are discussed.Ph.D.

Full textAbstract:
The aim of the thesis is a psychoanalytic and group analytic theorization of racism in general and colourracism in particular in the clinical context in Britain. Following a critical survey of the notion of race, it is suggested that of more significance than race, is the activity of racialization in which the notions of black and white play a central role. The definition of racism proposed is that racism is any use of the idea of race as an organizing principle. Next, explanations of racism are extracted from the theories of Freud, Klein, Fairbairn and Winnicott. This is followed by a critical review of the literature on racism and prejudice found in the main psychoanalytic journals. It is found that the psychoanalytic take on racism is limited in what it can achieve because it is too internalist and individualistic, and so cannot take account of the group phenomenon of racism. The study then gives abbreviated accounts of engagements with racism in the works of Adorno, Kovel, Wolfenstein, Fanon, Rustin and de Zulueta. The thesis now turns its attention from the level of the individual to the level of the group. The group analytic theory of S.H. Foulkes is introduced, in particular his description of the social unconscious. The ideas of Norbert Elias are used to extend group analytic theory to generate a psycho-social theory in which the structures of society are shown to be reproduced in the structure of psyches. The argument continues, that if society is colour-coded, then so is the psyche. Next, the semantic history of the terms black and white in the English language was traced. This included the use of these terms in the Authorized Version of the Bible. It was found that many of the associations with blackness which are taken to be timeless - death, anger, etc. - occur in the last few hundred years. The semantic evidence shows, that before blackness and whiteness could became the servants of racism, they were cathected with negativity and positivity. Following this they were increasingly used as parts-of-names as a way of signalling the value and status of the named. From the 1600's, the confluence of an increasing sense of negativity with the notion of blackness, the naming of non-European "thems' as black, when combined with the labelling of emotions and behaviours progressively designated as disagreeable as black, give credence to the idea that societies and psyches were being divided in colour-coded ways. A general theory of difference was developed based on the work of Matte-Blanco (bilogic), Foulkes (social unconscious), Elias (power-relations) and Winnicott (identity formation). The model of human beings that is generated by this theorization is one in which the forms of psyche are predicated on the forms of society, with the two in a recursive relationship to each other. Components of this model include an alternative model of the unconscious, and a problematizing of the notion of the whole. This theory was applied to the territory of race and racism. The resulting theory of racism is an integration of insights from three domains - the cognitive, the emotional and the sociological. Thus racism can no longer thought of as primarily a result of splitting and projection, but as a complex psycho-social phenomenon that is driven by the pragmatics of the power-relations in the world. Whilst psychological mechanisms play a critical role in this process, they are not elevated as causal agencies. Finally, some indication is given of the resulting modifications required of the practices of psychotherapy - in particular it is argued that the notion of the transference needs to be extended to include the historical relations between groups of people.

Full textAbstract:
Optical pose recognition of the hand is an extremely attractive method for user-computer interaction in many applications. The image of a hand in the frame of a video camera is processed and the pose it is making, its current finger configuration, is detected. Often combined with position tracking, it allows for a very natural way of giving commands. Furthermore, it alleviates the use of sometimes cumbersome pieces of hardware. Within immersive virtual reality systems, the liberty of movement of the commanding hand requires extra considerations not normally dealt with by typical optical hand posture recognition interfaces for desktop system applications. This research proposes an artificial neural network approach to the recognition of hand postures. The optical capture inside an immersive virtual reality workspace and the extraction of features of this hand are facilitated by the use of a specially coded color glove.

Full textAbstract:
Photographic Surface photometry in the Johnson B, R and I passbands of eighteen galaxies within 3° of the Virgo cluster 'core' is presented in this work. U.K. National facilities and STARLIKK common-user software were used to produce major and minor-axis luminosity profiles, colour-difference profiles, isophotal maps, equivalent profiles, and standard luminosity parameters for each galaxy in each passband. Standard techniques have been applied to the equivalent profiles to produce decomposed bulge and disk components for each galaxy. Solutions which are demonstrated to be realistic representations of the programme galaxies are amalgamated with previously-published independent data to construct homogeneous data sets. Nearly all the lenticular systems surveyed display vestigial disk structure or unusual features in the colour-difference profiles. Statistical analysis of the constructed data sets reveals no significant structural differences in the bulge components of disk systems as a function of morphological type, in contradiction with the earlier results of Dressier (1980). Significant differences in the disk components as a function of morphological type are found in the B-band data, but not the I-band data, in agreement with the results of Hamabe (1982) and Boroson et al. (1983b) respectively. The primary objections to the production of lenticular galaxies from spiral progenitors appear to have been discredited, together with several intrinsic-formation theories, and the results presented in this survey are considered strongly supportive of the hypothesis of a common origin of disk systems of all morphological types. The conclusion that at least some fraction of lenticular systems must have looked like spiral galaxies at some time in their history seems almost inescapable.

Full textAbstract:
This thesis introduces a new robust and high precision methodology and corresponding techniques for reconstructing three-dimensional (3-D) views of real objects from one single two-dimensional (2-D) image. The reconstruction process relies on obtaining the two dimensional image of a real object from a camera, on which a colour coded structured light is projected. The method does not require any a-priori knowledge of the absolute positioning or orientation of the camera and the projector which illuminates the scene with the colour coded structured light. Prior to the 3-D reconstruction steps, a calibration process is used to provide a high precision calculation of both the camera's and the projector's intrinsic and extrinsic parameters. These parameters are essential to the 3-D object reconstruction technique as introduced in this thesis. The structured light is used to determine unique patterns on the object's surface. The lines provide a series of control points which once extracted from the object's 2-D view, are used in the creation of Non-Uniform Rational B-Spline (NURBS) curves in 2-D. Those NURBS curves are then projected into space to eventually re-create a 3-D surface. The technique's precision depends on the structured light sampling rate adaptation on the object surface. In a recent test, a 7 tau (thousands of an inch) precision was achieved with a relatively smooth object.
The thesis will focus on the 3-D reconstruction of an object based on its single 2-D view. The approach proposed is end-to-end since it handles all the steps necessary to go from a 2-D view of an object to its modelization using NURBS curves and eventually to a surface in 3-D which can be manipulated with 3-D editing software on a computer monitor. The thesis's results are applicable to many domains. One of those domains is the CAD/SLA systems for manufacturing applications. Furthermore, NURBS surfaces can compress the 3-D image of a real object in a very efficient manner.

Full textAbstract:
The meaning of and motivations behind self-identification is a contentious topic within “the Black community.” The thesis examines the articulation of “Black” and/or “African” identities as means of gaining access to Nova Scotia’s Black Business Initiative (BBI), a state-funded organization mandated with “fostering a dynamic and vibrant Black presence” in the Nova Scotian business community. It is based on ethnographic fieldwork conducted in Halifax in 2013, including interviews with a diverse representation of 36 participants who self-identified as either "Black" or "African." Viewed as a rare redress effort directed toward and run by Blacks, the BBI is a highly visible site of contestation and competition between “indigenous Blacks” and more recently arrived “African Nova Scotians” from the African continent and Caribbean islands over the boundaries of native and foreign Blackness. The thesis argues that a group historically positioned as “Black” (i.e. Other) within a lasting narrative of displacement – both in the Americas in general, and academic diaspora discourse specifically – can be seen as adopting and adapting a discourse of indigeniety as an act of political and economic empowerment. Stuart Hall’s theoretical understanding of the articulation and positioning of Black identities is used to frame a discussion on the coupling of a distinct group’s lived experiences of subjugation and marginalization in place (i.e. Blackness) with a political and juridical ideology of belonging and entitlement to state recognition and resources (i.e. indigeniety) as a means of securing racially directed resources. It therefore challenges Paula Madden’s (2009) overly simplistic critique of this community as creating a hierarchy of Blackness and performing an erasure of Mi’kma’ki through its claims of Black indigeniety.

Full textAbstract:
Rates of survival of victims of sudden cardiac arrest (SCA) using cardio pulmonary resuscitation (CPR) have shown little improvement over the past three decades. Since registered nurses (RNs) comprise the largest group of healthcare providers in U.S. hospitals, it is essential that they are competent in performing the four primary measures (compression, ventilation, medication administration, and defibrillation) of CPR in order to improve survival rates of SCA patients. The purpose of this experimental study was to test a color-coded SMOCK system on:1) time to implement emergency patient care measures 2) technical skills performance 3) number of medical errors, and 4) team performance during simulated CPR exercises. The study sample was 260 RNs (M 40 years, SD=11.6) with work experience as an RN (M 7.25 years, SD=9.42).Nurses were allocated to a control or intervention arm consisting of 20 groups of 5-8 RNs per arm for a total of 130 RNs in each arm. Nurses in each study arm were given clinical scenarios requiring emergency CPR. Nurses in the intervention group wore different color labeled aprons (smocks) indicating their role assignment (medications, ventilation, compression, defibrillation, etc) on the code team during CPR. Findings indicated that the intervention using color-labeled smocks for pre-assigned roles had a significant effect on the time nurses started compressions (t=3.03, p=0.005), ventilations (t=2.86, p=0.004) and defibrillations (t=2.00, p=.05) when compared to the controls using the standard of care. In performing technical skills, nurses in the intervention groups performed compressions and ventilations significantly better than those in the control groups. The control groups made significantly (t=-2.61, p=0.013) more total errors (7.55 SD 1.54) than the intervention group (5.60, SD 1.90). There were no significant differences in team performance measures between the groups. Study findings indicate use of colored labeled smocks during CPR emergencies resulted in: shorter times to start emergency CPR; reduced errors; more technical skills completed successfully; and no differences in team performance.

The ideas within this thesis are meant to clarify my explorations, research and painting practice during my studies at Virginia Commonwealth University. I expand on my general statements about being fascinated by advancing technologies and concerned about the after effects of these advancements. The writing explores my curiosity about the internal, skeletal structure of things and how they operate. I explain how the paintings are idiosyncratic hybrids that evoke animation, imaginary scientific propositions, blueprints, maps, and advancing technologies. The work combines these interests with my observations of day-to-day experiences. Isolated events provide found compositions which I then manipulate: a seemingly mundane bike ride gets mapped into a well–ordered schematic of social interaction.

Full textAbstract:
Textile wastewater contains very high concentration of color, COD, suspended solids and other pollutants. Methods such as reverse osmosis, nano-filtration and ultrafiltration are known to be effective to remove some pollutants but these methods are very expensive. A new treatment approach which is the combination of freezing technology and Microbial Fuel Cell technology has been studied in this thesis work and seems to have great potential to remove color and COD from textile wastewater. Freezing splits a diluted stream into two different streams; one stream in which water is transferred into ice with a low pollutant concentration leaving a concentrated stream with pollutants. Microbial fuel cell uses the concentrated stream to convert biochemical energy into electrical energy. Three different types of substrates, KMnO4 solution, municipal wastewater and orange juice, were studied. Freezing technology can produce high quality water by neutralizing pH-value; close to 7.0, removal of COD is more than 95% and separating color by almost 100%. Similarly MFC can remove color, and COD by 88.8% and 73.6% respectively. The maximum generation of electrical power by MFC was estimated to 1.03 mW/m2 of electrode area. The findings suggest that this new approach of textile wastewater treatment can be a costeffective way to remove pollutants from textile wastewater while generating some electricity.

Nowadays, natural polymeric materials extracted from plants are the new alternatives for synthetic chemicals in water and wastewater treatment. The aim of this study is to evaluate the ability of Cassia fistula seed gum (CFG) as a coagulant aid with PAC in the treatment of textile wastewater. Jartest experiments were carried out to identify the optimal parameters of coagulation-flocculation for removing color and COD in synthesis wastewater containing Methyl blue and RB21 dyes, including pH, settling time, PAC dose, the optimal CFG dosage in comparing with the cationic polymer. After that, actual textile wastewater was treated by using PAC, PAC plus cationic polymer, and PAC plus CFG for evaluating the role of CFG. CFG supplementation has assisted the process effects at nearly 98% color, 85% COD for RB21 and 90% color, 70% COD for MB at the best dose of CFG 0.15 mL and 0.1 mL, respectively. The optimized parameters for the coagulation of real textile wastewater using PAC were pH = 6 and dose = 0.6 mL can removal 66% of color. By adding CFG to PAC, the efficient of treatment was increased about 70% even at the lower dosage of PAC and CFG (0.5 mL for each reagent). The yield of combining PAC and polymer was a little bit lower than PAC and CFG, for instant 68% color was decreased at the same condition. These achievements demonstrated a workable substitute of natural products such as Cassis fistula seed gum for synthetic chemical products in coagulation-flocculation process.Hiện nay các loại vật liệu sinh học chiết xuất từ thực vật đang được nghiên cứu ứng dụng trong xử lý nước và nước thải thay cho các chất hóa học. Mục tiêu của nghiên cứu này là đánh giá hiệu quả của việc sử dụng gum được chiết xuất từ hạt cây Muồng Hoàng Yến (MHY) làm chất trợ keo tụ trong xử lý nước thải dệt nhuộm. Thí nghiệm Jartest được tiến hành nhằm xác định các điều kiện tối ưu cho quá trình xử lý nước thải tổng hợp chứa thuốc nhuộm Methyle Blue (MB) và RB21 bao gồm pH, thời gian lắng, liều PAC, liều gum MHY và liều polymer. Sau đó tiến hành xử lý nước thải thật với các điều kiện thích hợp đã xác định nhằm đánh giá vai trò của gum MHY. Gum MHY làm tăng hiệu quả của quá trình xử lý, đạt gần 98% đối với độ màu, 85% COD đối với RB21, 90% độ màu và 70% COD đối với MB với liều lượng tương ứng là 0,15 mL và 0,1 mL. Các thông số tối ưu cho quá trình xử lý trên mẫu nước thải thật là pH = 6, liều PAC = 0.6 mL có thể làm giảm 66% độ màu. Bổ sung gum MHY làm chất trợ keo tụ giúp gia tăng hiệu quả xử lý màu lên 70% dù với liều lượng rất thấp là 0,5 mL. Hiệu suất xử lý khi sử dụng kết hợp PAC và polymer thấp hơn trong trường hợp sử dụng PAC và gum MHY, cụ thể khoảng 68% độ màu được xử lý ở cùng một điều kiện. Những kết quả này cho thấy tiềm năng của việc sử dụng các vật liệu gum tự nhiên nhằm thay thế cho các hợp chất hóa học trong các quá trình keo tụ tạo bông để xử lý nước thải.

Full textAbstract:
A coloring of a graph is an assignment of colors to its vertices so that no
two adjacent vertices are given the same color. The chromatic number of a
graph is the least number of colors needed to color all of its vertices. Graph
coloring problems can be applied to many real world applications, such as
scheduling and register allocation. Computationally, the decision problem
of whether a general graph is m-colorable is NP-complete for m ≥ 3.
The graph studied in this thesis is a well-known combinatorial object,
the k-dimensional hypercube, Qk. The hypercube itself is 2-colorable for all
k; however, coloring the square of the cube is a much more interesting problem.
This is the graph in which the vertices are binary vectors of length k,
and two vertices are adjacent if and only if the Hamming distance between
the two vectors is at most 2.
Any color class in a coloring of Q2k is a binary (k;M, 3) code. This thesis
will begin with an introduction to binary codes and their structure. One
of the most fundamental combinatorial problems is finding optimal binary
codes, that is, binary codes with the maximum cardinality satisfying a specified
length and minimum distance. Many upper and lower bounds have
been produced, and we will analyze and apply several of these. This leads
to many interesting results about the chromatic number of the square of the
cube.
The smallest k for which the chromatic number of Q2k is unknown is
k = 8; however, it can be determined that this value is either 13 or 14.
Computational approaches to determine the chromatic number of Q28 were
performed. We were unable to determine whether 13 or 14 is the true value;
however, much valuable insight was learned about the structure of this graph
and the computational difficulty that lies within. Since a 13-coloring of Q28
must have between 9 and 12 color classes being (8; 20; 3) binary codes, this
led to a thorough investigation of the structure of such binary codes.

Full textAbstract:
Audience Response Systems (ARS) give a facilitator accurate feedback on a question posed to the listeners. The most common form of ARS are clickers; Clickers are handheld response gadgets that act as a medium of communication between the students and facilitator. Clickers are prohibitively expensive creating a need to innovate low-cost alternatives with high accuracy. This study builds on earlier research by Gain (2013) which aims to show that computer vision and coloured poll sheets can be an alternative to clicker based ARS. This thesis examines a proposal to create an alternative to clickers applicable to the African context, where the main deterrent is cost. This thesis studies the computer vision structures of feature detection, extraction and recognition. In this research project, an experimental study was conducted using various lecture theatres with students ranging from 50 - 150. Python and OpenCV tools were used to analyze the photographs and document the performance as well as observing the different conditions in which to acquire results. The research had an average detection rate of 75% this points to a promising alternative audience response system as measured by time, cost and error rate. Further work on the capture of the poll sheet would significantly increase this result. With regards to cost, the computer vision coloured poll sheet alternative is significantly cheaper than clickers.

Full textAbstract:
INTRODUÇÃO: O ultrassom transcraniano colorido (UTC) é um eficiente método para avaliação da circulação intracraniana e do fluxo sanguíneo cerebral em diversas condições clínicas incluindo o acidente vascular isquêmico agudo. Uma das principais limitação deste método reside na incapacidade de insonação intracraniana adequada através da janela transtemporal em até 20% dos pacientes. Neste contexto, surge a necessidade do desenvolvimento de uma metodologia estruturada que permitisse caracterizar a qualidade da janela transtemporal de forma mais detalhada e objetiva. No presente estudo, objetivamos: determinar a frequência de visualização dos principais marcos anatômicos pela insonação com UCT utilizando-se a janela transtemporal em pacientes com AVCI agudo; classificar o grau de dificuldade na visualização da primeira porção da artéria cerebral média (ACM) ipsilateral ao lado insonado; determinar a influência da idade, sexo, etnia no na qualidade da janela transtemporal pelo UTC. METODOLOGIA: Avaliamos prospectivamente todos os pacientes adultos, consecutivos, com o primeiro e único episódio de acidente vascular isquêmico no período de julho de 2014 a janeiro de 2015 com um exame de UTC (modo B e Doppler colorido). Dois examinadores classificaram a qualidade da janela transtemporal pelo modo B utilizando uma escore baseado na qualidade da visualização de referencias anatômicas (osso temporal contralateral, asa menor do esfenoide ipsilateral e mesencéfalo) variando de 0 (janela ausente) a 9 (excelente janela). Os preditores independentes de uma boa visualização do sinal da ACM ao UTC foram identificados através de um modelo de regressão logística multivariada selecionado pelo método backward. A acurácia do escore do modo B foi avaliada através dos parâmetro de sensibilidade, especificidade e estatística C (curva ROC). RESULTADOS: entre os 200 paciente incluídos no estudo (55% do sexo masculino e com idade média de 61,17 ± 15,22 anos) o osso temporal contralateral não foi visualizado em 48,5% dos casos, o mesencéfalo foi visualizado em 65% e a asa menor do esfenoide foi visualizada em 66%. A porção proximal da artéria cerebral media (M1) foi visualizada em 62% dos casos. Na análise multivariada, a idade (OR: 0,95; IC95%:0,92 - 0,99; p=0,011) e a pontuação no escore do modo B (OR: 2,97; IC95%:1,93- 4,55; p<0,001) foram preditores independentes de visualização do sinal da ACM ao UTC. A pontuação no escore do modo B mostrou um preditor acudado para subsequente visualização da artéria cerebral médica pelo Doppler colorido com uma área sob a curva ROC de 0,896 (p<0,001). O escore de 2 apresentou uma sensibilidade e especificidade de 80 e 87% para este fim, respectivamente. CONCLUSÃO: O escore do modo B baseado na visualização de referência anatômicas intracranianas pelo modo B do UTC é uma ferramenta útil com boa acurácia para capacidade de visualização do fluxo da artéria cerebral media ipsilateral ao UTC. Este escore permite descrever de forma mais detalhada a qualidade de janela transtemporal ao UTC, em suas diferentes aplicações.INTRODUCTION: Transcranial Color-Coded Sonography (TCCS) is an widely-used method to assess the intracranial circulation and cerebral blood flow in several clinical conditions including acute ischemic stroke. One of the main limitations of this technic is related to the quality of the transtemporal window, which is poor in about 20% of cases. In this context, it is important to develop an structured approach to better define the quality of the transtemporal window. In this study we aimed to evaluate how frequently the main anatomic landmarks can be adequately visualized by TCCS in acute stroke patients using the transtemporal window; to assess the proportion of patients in which the ipsilateral middle cerebral artery of visualized by TCCS; and to identify the main predictors of a poor transtemporal window on TCCS. METHODS: We examined 200 consecutive acute ischemic stroke (AIS) patients, from July 2014 to January 2015. All patients underwent prospective TCCS evaluation. Visualization of the contralateral temporal bone (CTB), midbrain (MB) and lesser sphenoid wing (LSW) was scored on B-mode images. The resulting B-Mode Score varied from 0 (poor visualization) to 9 (perfect window). A multivariate logistic regression model (backward selection) was used to identify the independent predictors of visualization of the MCA signal by TCCS. The relationship between these B-Mode Score and visualization of the proximal portion of the ipsilateral MCA was assessed in terms of sensitivity, specificity, ROC curve and C statistics. RESULTS: Among 200 AIS patients (male 55%; mean age, 61.17 ± 15,22 years), CTB was invisible\' in 48,5%, the MB was visualized in 65%; and the LSW was seen in 66%. The M1 segment of the MCA was detected in 62% of cases. After multivariate analysis, age (OR: 0.95; 95CI%:0.92-0.99; p=0.011) and B-Mode score (OR: 2.97;95CI%:1.93-4.55; p<0.001) were independente predictors of visualization of MCA signal by TCCS. The BMode Score show good accuracy for the prediction of MCA visualization with an AUC of 0,896. (p<0,001) on the respective ROC curve. A cut-off of 2 on the B-mode score showed a sensitivity of 80% and a specificity of 87% for adequate MCA visualization by TCCS. CONCLUSION: The B-mode Score, which is based on the visualization of intracranial anatomical landmarks on B-Mode, appears to be a reliable way to characterize the quality of the transtemporal window, with a good accuracy as predictor for visualization of the ipsilateral MCA on TCCS. This score may allow more detailed characterization of the transtemporal window for different clinical applications of TCCS.

The landfill leachate is commonly treated for non-biodegradable organic matters, ammonia and colour. Experimental investigations using polyaluminium chlorite (PAC) and UV/O3 have been conducted for the determination of optimal pH value, reaction time and PAC concentration for the removal of chemical oxygen demand (COD) and colour. In pre-treatment coagulation stages, the highest COD and colour removal efficiencies were observed at the concentration of PAC ≥ 3,000 mglG1 and pH values between 7 and 8. However, these experiments also indicated significant removal efficiency for PAC starting with concentrations of 1,500 mglG1. The efficiency of COD and colour removal were approximately 30% and 70%, respectively. Similar efficiencies have been observed also during the second treatment stage where UV/O3 processes were used to treat coagulated leachate. After UV/O3 application, the pH of leachate reached the optimum value of 7.5 whereas the highest COD and colour removal efficiency was 55% and 72%, respectively, and the optimal reaction time was achieved after 80 minNước rỉ rác sinh ra từ bãi chôn lấp chất thải rắn cần được xử lý các thành phần chất hữu cơ khó phân hủy sinh học, xử lí amoni và độ màu.

Full textAbstract:
A straightforward, rapid method to create colloidally stable and brightly luminescent core/shell CdSe-based nanoplatelets (NPLs) with fluorescence quantum yields (QYs) up to 50% is demonstrated. A layer-by-layer deposition technique based on a two-phase mixture ‒ consisting of a nonpolar phase which includes the NPLs, and a saturated ionic polar phase ‒ to separate the reagents and hinder the nucleation of the shell material is used. The deposition of the first sulfur layer leads to a significant red-shift (by more than 100 nm) of the optical absorption and emission of the NPLs. Hence, by varying either the sulfur precursor content or the reaction time one can precisely and continuously tune the absorption and emission maxima from 520 to 630 nm. This evolution of the absorption onset during the shell growth is explained quantitatively using density-functional theory and atomistic statistical simulations. The emission can be further enhanced by exposure of the NPL solution to ambient sunlight. Finally, it is demonstrated that the core/shell NPLs can be transferred from the organic solution to aqueous media with no reduction of their QY that opens the door to a broad range of practical applications.

Os avanços em tecnologia multimídia ocasionou um grande crescimento da quantidade de imagens digitais, em consequência disso, cresceu também a necessidade de métodos mais eficazes e eficientes para armazenar e recuperar esse conteúdo multimídia. A maioria dos métodos propostos na literatura alcançam altos níveis de eficiência e eficácia (a cima de 70% de precisão), entretanto grande parte delas executam experimentos usando bases de imagens pequenas (menos de 10.000 imagens), previamente classificadas em categorias bem de nidas, facilitando assim a tarefa de busca e, consequentemente aumentando os níveis de precisão dos descritores avaliados. Por outro lado, quando esses métodos são avaliados em grandes coleções heterogêneas, o nível de precisão e relativamente baixo. Pensando nesse problema, esta dissertação propõe o descritor Local Color Pixel Classication (LCPC), um método baseado em análise local para busca em grandes bases de imagens. A abordagem proposta extrai características de cor, classificando os pixels como borda ou interior, usando o mesmo esquema de classificação do método Border/Interior Pixel Classication (BIC), através de um esquema de particionamento simples, mas muito eficiente e eficaz para incorporar informações espaciais sobre o conteúdo visual da imagem. Experimentos foram conduzidos usando três bases de imagens, incluindo uma com mais de 100.000 imagens coletadas da Web. Os resultados obtidos mostram que a abordagem proposta e bastante superior quando comparado com outros descritores visuais previamente apresentados na literatura, com ganhos em precisão média de 51% até 105%

QR Code is a popular 2-D bar code. Traditional QR Code is composed of black and white blocks. Therefore, the content is unknown before scanning. If a color icon, such as trademarks, can be embedded, the usability is better. Researchers proposed some methods to improve the appearance of QR Code, making QR Code itself provide a visual message. Referencing from other previous works, in order to avoid damaging the coding structure, the QR Code visual effects must accommodate the integrity of the coding structure to have a better accuracy. Nowadays, with the widely used of electronic displays, QR Code does not only appear on paper, but also appear in electric billboards. As a result, the color icon QR Code can be shown as animations dynamically, making economic value of QR Code higher. Generating dynamic color QR Codes which keeps the integrity of its structure, is the goal of this thesis. In this thesis, the halftone technology, and the concept of the center module is applied to get the black and white block QR Code. Some generated blocks will cover the embedded icon in the QR code, and is uncovered using the Gauss-Jordan elimination method. The characteristics of the QR reader is also considered to reduce the center module. Finally, a series of color icon QR Codes to are used to get the dynamic color icon QR Codes. Our method produces a number of color icon QR Codes and dynamic color icon QR Codes. Through the user scan experiment, we validated that the QR Code generated by our method can be identified by the scanning software commonly used in the market.

Abstract The Quick Response code (the QR code) is a two-dimensional matrix barcode which was invented by Denso Wave Japanese corporation. People utilize the smart phone to obtain information such as the URL, the text data, the image from the QR code. Reversible data hiding is a branch of steganography. The main characteristic of reversible data hiding is that the media (e.g., the pictures or the images) can be recovered to initial state after information is taken out. Reversible data hiding for QR code is a newly developed application in watermarking researches. In this issue, the presented method is to insert the QR code into the original image. After scanning the image containing the QR code, the QR code can be removed and the original image can be recovered by reversible data hiding. There are two key points in designing a reversible data hiding for QR code scheme: the lower hiding information and the reduced image distortion. This paper proposes a reversible data hiding in color image for QR code applications. The proposed method enables to embed the QR code into the color image to produce visible watermark. First, the embedding approaches are based on the changing pixels. After the embedding process, it is visible to human. Some information is embedded by using reversible data hiding. It can be extracted watermark and recovered the original image completely.

For thousands of years, the culture characteristics of Chinese clothing decoration has been the product of combination and interaction of colorful appearance and the concept of“human and nature in harmony”. This thesis selected the topic and concentrated the research in the garment coloring only. Since the use of colors in garment has based on the traditional philosophy thinking to attain the state of human and nature in one, so as to demonstrate the effect of garment decoration system significantly impact country’s political and judicial system. Western system has a specific subject of “color theory” to understand the effect of color and to study its application. In this subject, it studies the scientific effect of light source color combination or color pallet mixing to express the contrast of “original colors” and “mixed colors”. But this western subject matter also limited to the multi-facet effect study in human visual reaction and the aesthetic appearance. The effect of color code in thousands years of Chinese history not only included the same effect as in the West but also the exceptional impact on the political system. Given this contrast of East and West, it demonstrates the tremendous culture gap. This enormous difference inspired this research to study the role of color code in Chinese garment history. This research was expected to extend various previous works to further analyze the historical recording in the area of color code of Chinese traditional clothing system, systematically summarize the finding, and provide the proof to enhance the overall understanding in the subject. The author further categorized the finding in chapters to complete the study with a conclusion.

In this thesis, we propose a system to evaluate a user’s performance in a real-time manner. By utilizing the ability of Kinect V2 sensor to capture human motion, the system records a professional user’s motion. This recording can be used as a reference motion for novice users to practice. This way, the presence of the professional is not needed. Later on, the novice user can re-play the recording inside a 3-dimensional environment and follow through in order to practice the motion. In this 3-D environment, the system presents the motion by a 3-D character, retargeted according to the novice’s body. This retargeting system allows a novice user to view the motion using a 3-D model with the size relative to his/her own body size. This system also provides feedback by changing the color of the model to indicate the correctness of user’s motion. This way, the feedback can easily be recognized by the novice, thus making motion learning more effective.
